知识精讲
知识点01 invented的用法
【课文详解】When was it invented？它是什么时候发明的
【句型剖析】…was invented …句意为“某物被发明……”，是被动句式。例如：
The abacus was invented in the sixteenth century by the Chinese.
算盘在十六世纪由中国人发明的。
Who was the light bulb invented by？灯泡是由谁发明的？
【拓展】
被动语态的结构是：主语+be done（及物动词的过去分词），be是随人称和时态变化而变化的。
（1）一般现在时的被动语态：am/ is/ are done 例如：
The blackboard is cleaned by the students every class.
黑板每节课都被学生擦干净。
（2）一般过去时的被动语态：was/ were done 例如：
The computer was invented last century.
电脑是上个世纪被发明的。
（3）一般将来时的被动语态：shall/will be done 例如：
A new school will be built in our village next year.
明年一所新的学校将在我们村庄建设。
（4）现在进行时的被动语态：am/is/are being done 例如：
A sports meeting is being held in our school now.
运动会正在我们学校举行。
（5）现在完成时的被动语态：have/has been done 例如：
All of the work has been finished since I came here.
自从我来这里以来，所有的工作都已经完成。
（6）含有情态动词的被动语态：can/may/must/should be done 例如：
Your homework must be handed in after school.
你们的家庭作业必须在放学后交上。
（7）复合宾语的被动语态：原来的句子是“主语＋谓语＋宾语＋宾语补足语”，在变被动语态的时候只能将宾语变为被动语态的主语，宾语补足语变为被动语态的主语补足语。主动语态中宾语补足语是省掉to的不定式时，在被动语态中需要还原to。
They heard her sing an English song at the party.
他们在晚会上听到她唱了一首英语歌。
变为被动语态是：She was heard to sing an English song at the party.
【即学即练】It’s said that tea __________ by accident about five thousand years ago.
A．was invented B．is invented C．will be invented D．were invented
【答案】A
【详解】句意：据说茶是大约5000年前偶然发明的。
考查被动语态。分析句子可知tea和invent之间是被动关系，根据“five thousand years ago.”可知句子应用一般过去时的被动语态：was/were+done，且tea是不可数名词，be动词应用was，故选A。
知识点02 such的用法
【课文详解】Is it really such a great invention? 它真的是如此了不起的一项发明吗？
【句型剖析】such用作形容词，修饰名词。主要用法有：
(1)such＋a(an)＋adj.＋单数可数名词＋that从句。
He got such a bad cold that he coughed day and night.他得了如此重的感冒以至于整日整夜咳嗽。
(2)such＋adj.＋不可数名词＋that从句。
She has made such great progress that many people like her. 她取得如此大的进步，许多人都喜欢她。
(3)such＋adj.＋名词复数＋that从句。
They are such interesting books that we all like them. 它们是如此有趣的书，我们都喜欢它们。
such (a/an) + adj. + n. 意为＂如此……的(一个)……＂。
Why do you buy such expensive clothes?
【即学即练】It’s ________ a nice invention that I’m wondering who ________ it.
A．so; invented B．such; invented
C．so; did invent D．such; did invent
【答案】B
【详解】句意：这是一项很好的发明，我想知道是谁发明的。
考查such … that …句型和过去时。在“so … that”和“such … that”句型中，so后边可加形容词或副词，而such后要用名词，第一空要修饰的是名词invention，故应用such，A、C选项可排除。第二空根据语境可知，此处在问是谁发明了它，动作发生在过去，故应用动词过去式，故选B。
知识点03 mention的用法
【课文详解】For example, it mentioned that zipper was invented by Whitcomb Judson in 1893.例如,它提到拉链是1893年由惠特科姆·贾德森发明的。
【句型剖析】mention作及物动词,意为“提到;说到”,后面可接名词、代词、动名词或that从句作宾语。
mention+that从句
用法 mention sb./sth.(to sb.)(向某人)提起某人/某事
mention doing sth.提到做某事
He mentioned that the food was invented by a Chinese.
他提到这种食物是由一个中国人发明的。
Nobody mentioned it to me.没人向我提过这事。
Whenever I mention having dinner together, he says he's too busy.
无论何时我提起一块儿吃饭,他都说太忙。
【拓展】 “Don't mention it.”常用于口语中,多用作回复他人道谢或道
歉时的答语,意为“不用谢;没关系”
—Thank you very much.多谢你了。
—Don't mention it.不客气。
—I'm sorry to have troubled you.抱歉打扰你了。
—Don't mention it.没关系。
【即学即练】—How could I thank you enough?
—________! Any other man in that case would have done that.
A．Don’t mention it B．No problem
C．It depends D．Of course not
【答案】A
【详解】句意：——我该怎么感谢你才好呢？——不用谢！在那种情况下，其他任何人都会那样做。
考查情景交际。Don’t mention it别客气；No problem没问题；It depends 看情况而定；Of course not当然不会。根据“How could I thank you enough?”可知，对别人的感谢应说不客气，故选A。
知识点04 be used的用法
【课文详解】But at that time, it wasn’t used widely.但在当时，它并没有被广泛使用。
【句型剖析】 sth. be used…是被动语态句式，表示“某物被使用……”。常用如下搭配：
（1）be used for 意思是“被用来做某事”，for是介词，它的后面用名词或者动名词作宾语。例如：
Knives are used for cutting things. 刀是用来割东西的。
（2）be used as意思是“被作为……使用”，as是介词，意思是“作为”。 它强调被当作工具或者手段来使用。例如：
Our classroom is used as a reading-room. 我们的教室被用来当阅览室使用。
（3）be used by意思是“被……使用”，by后面跟人或者物，表示强调动作的使用者。
This radio is often used by my mother. 这台收音机经常被我的妈妈使用。
（4）be used to do something意思是“被用来做某事”，和be used for doing是同义词短语。
It is used for learning English.＝It is used to learn English. 它是被用来学习英语的。
【即学即练】Last month Tencent Meeting(腾讯会议) ________ to study by us at home.
A．is used B．used C．was used D．was using
【答案】C
【详解】句意：上个月，我们用腾讯会议在家学习。
考查时态和语态。根据“Last month”可知，应该使用一般过去时；根据“Tencent Meeting”和“use”之间构成被动语态，所以应该使用一般过去时被动语态。故选C。
知识点05 It is said that的用法
【课文详解】It is said that a Chinese ruler called Shen Nong was the first to discover tea as a drink.据说,有一位叫作神农的中国统治者最早发现茶可以饮用。
【句型剖析】It is said that…是一个固定搭配的句型，it是形式主语，真正的主语是后面的that从句。它的
思是“据说……”。例如：
It is said that Mary is very happy in London. （主语从句）
= They say that Mary is very happy in London.（宾语从句）
据说玛丽在伦敦是非常幸福的。
【拓展】
另外类似的句型有：It is believed…（人们相信），It is reported that …（据报道），It is supposed that… （据猜测）It is known that...众所周知......。例如：

A．will hold B．was held C．will be held
【答案】C
【详解】句意：据了解，2024年夏季奥运会将在巴黎举行。
考查一般将来时的被动语态。主语是动作的承受者，根据“2024”可知，此处用一般将来时的被动语态。故选C。
知识点06 smell的用法
【课文详解】It produced a nice smell so he tasted the brown water.它散发出一股香味,因此他尝了一下这棕色的水。
【句型剖析】 smell
(1)作名词,意为“气味”,常与of连用,表示“......的气味”。
There's a delicious smell coming from the kitchen.厨房里传来一阵香味。
The air was filled with the smell of flowers.空气中弥漫着花香。
(2)作动词时有两种用法:表示“发出......的气味”时,smell是连系动词,表示“闻到”时,smell是及物动词,不用于进行时。
The fish smells delicious.鱼闻起来很香。
Can you smell something?你闻到什么气味了吗?
【归纳】feel,look, sound, smell, taste这五个动词均可作连系动词，后面接形容词作表语,说明主语所处的状态,其意思分别为“感觉”,“看”,“听”,“闻”,“尝起来”。
I'm feeling terrible.我感到难受极了。
The soup tastes delicious.这汤味道不错。
These flowers smell very sweet.这些花闻起来很香。
【即学即练】— Tim, have you ever heard the song Together for a Shared Future?
— Yes, it ________ beautiful.
A．smells B．sounds C．feels D．looks
【答案】B
【详解】句意：——蒂姆，你听过《一起向未来》这首歌吗？ ——是的，听起来很美。
考查系动词。smells闻起来；sounds听起来；feels摸起来；looks看起来。根据“have you ever heard the song Together for a Shared Future?”可知，《一起向未来》是一首歌曲，应该是听起来很美。故选B。
知识点07 until的用法
【课文详解】 In England, tea didn’t appear until around 1660, but…在英国，茶直到1660年左右才出现，但…

例如：
She stayed there until 9 o’clock. 她一直等到9点钟。
We waited until the rain stopped. 我们等到雨停了。
(2) until用在肯定句中，多与持续性的动词连用。如：stand/wait/stay等，表示主句动作的终止时间。
(3) until可用于否定句中，即not…until…意为“直到……才”，常与非延续性动词连用。如：open/start/leave/arrive等，强调主句动作开始的时间。例如：
The child didn’t go to bed until his father came back.
直到父亲回来，那个孩子才睡觉。
【即学即练】It ________ discovered ________ the 17th century.
A．wasn’t; until B．didn’t; until
C．didn’t; before D．doesn’t; till
【答案】A
【详解】句意：直到十七世纪它才被发现。根据语义可知，主语与谓语之间是被动关系，因而使用被动语态：be+动词的过去分词。discovered是discover的过去分词。故选A。
知识点08 doubt的用法
【课文详解】Even though many people now know about tea culture, the Chinese are without doubt the ones who best understand the nature of tea.即使现在许多人知道茶文化,但中国人无疑是最懂茶之本质的人。

考法04 pleasure相关单词

A．fit B．noisy C．friendly
【答案】C
【详解】句意：——Sally，你觉得爱丽丝怎么样？——她是一个令人愉快的女孩，她总是对别人很好。我非常喜欢她。

考法05 take place与happen相关词组辨析
【辨析】take place与happen
take place
不能用于被动语态；常指事先安排或事发有因的事情。
happen
不及物动词，不能用于被动语态，常指偶然发生的事情。
【典例】—Hey, Tim. Our sports meeting has been put off. When will we have it again?
—I think our sports meeting ________ as soon as the rain stops.
A．takes place B．happens C．will take place D．will happen
【答案】C
【详解】句意：——嘿，蒂姆。我们的运动会延期了，我们什么时候再举行？——我想我们的运动会将在雨停后举行。结合语境理解可知，运动会还没有举行，要用一般将来时态来表达，首先排除A,B；happen / take place它们都可以表示“发生”，但是在用法上有区别，happen常指具体事件的发生，特别指偶然的或未能预见的事情；如要指事先安排或有准备的事情或活动发生时，通常要用take place，另外take place还有“举行”的意思。结合句意，故答案为C。
分层提分
题组A 基础过关练
1．（2021·河北·中考真题）These gifts ________ by children in their last summer holidays.
A．made B．were made C．make D．are made
【答案】B
【详解】句意：这些礼物是孩子们在上一个暑假里做的。
考查一般过去时的被动语态。主语gifts与谓语make之间为被动关系，故应用“be动词+过去分词”的被动语态结构，且根据last summer holidays提示，句子应用过去时，故空格处应用一般过去时的被动语态结构，故选B。
2．This pair of shoes________Mom, and it________very comfortable.
A．was made with; is felt B．were made from; is felt
C．were made by; feels D．was made by; feels
【答案】D
【详解】句意：这双鞋是妈妈做的，穿起来很舒服。
考查一般过去时的被动语态和动词的第三人称单数形式。be made with用……制作的/和……一起制作的；be made from由……制成；be made by由某人制成的。this pair of shoes表示这双鞋，作主语时谓语用单数，根据空后的Mom可知是由妈妈做的，故第一个空用was made by；第二个空表示穿起来很舒服，feel系动词，用主动语态表达被动含义。故选D。
3．I never doubt_______ he can do the job well, but I doubt_______ he will get here in time.
A．if; if B．that; that C．that; if D．if; that
【答案】C
【详解】句意：我从不怀疑他能把工作做好，但我怀疑他是否能及时赶到这里。
英语中引导的宾语从句中，如果doubt前有否定词时后面用that引导，而前面没有否定词时，要用whether或if或特殊疑问词来引导，表达疑问，故选C。
4．（2018·江苏南京·中考真题）---Simon, do you know who invented the kite?
---Sure! It ____ by Mozi over 2,000 years ago.
A．is invented B．invented C．was invented D．will be invented
【答案】C
【详解】句意：Simon，你知道谁发明了风筝吗？---当然，它是于2000多年前被墨子发明的。by引出动作的发出者，而前面的主语it（代指风筝）与选项动词之间是被动关系，事件发生于2000多年前，故句子用一般过去时态的被动语态来表达，答案选C。
【点睛】初中英语教材中出现了五种时态的被动语态及带有情态动词的被动语态。
（1）一般现在时被动语态的构成：助动词am/is/are + 及物动词的过去分词
English is spoken in many countries.
(2) 一般过去时被动语态的构成：助动词was/were + 及物动词的过去分词
Was this novel written by his father?
(3) 一般将来时构成：will/be going to do + be + 及物动词的过去分词
The baby will be taken good care of in the hospital.
(4) 现在完成时被动语态的构成：助动词have/has + been + 及物动词的过去分词

(5) 现在进行时被动语态的构成：am/is/are + being + 及物动词的过去分词

— Yes, I think he wanted to train their abilities of deep thinking.

【答案】D
【详解】句意：——你注意到在张先生的课堂上，学生们被问了一些为什么的问题吗？——是的，我想他是想训练他们的深度思考能力。
考查一般过去时的被动语态。主语the students是动作ask的承受者，根据“Did you notice”可知，时态是一般过去时，所以用一般过去时的被动语态，结构为was/were done。故选D。
6．—Do you know the song Gangnan Style?
—Of course. It interesting.
A．tastes B．smells C．sounds D．feels

考点：考查动词辨析。
7．（2019·北京·中考真题）My advice on how to save paper by my class last Monday.
A．accepts B．accepted C．was accepted D．is accepted
【答案】C

（2017·福建·中考真题）No one knows when the first kite was made. The first record of a kite was more than 2,000 years ago in China. Han Xin, the leader of an army, wanted to bring down a king. He decided to dig a tunnel (隧道）into the king’s palace. He flew a kite over the wall of the palace to make sure the length (长度）of its string (线).In this way, he could determine how long the tunnel should be.His men in the tunnel took the kite string with them. When they reached the end of the string, they knew to dig up.
Kites have been flown in Japan for hundreds of years. In the 1700s, kites were flown in autumn to give thanks for a good harvest. They were also flown to send good wishes to couples who had their first son. Today in Japan, kites are often flown as part of a celebration, such as the beginning of a new year. And kite festivals are held each year in many parts of the country.
Kites have been used for scientific purposes in the western world. In 1752，Benjamin Franklin tied a key to a kite and flew it in a storm to find out that lightening was a form of electricity. In the 1890s，Lawrence Hargrave invented the box kite to test ideas about flight. From 1898 until 1933，the United States Weather Bureau (气象局） used box kites to collect weather data. The Wright brothers also experimented (试验）with kites. What they learnt helped them make the first airplane flight in 1903.

点睛：词义猜测题阅读理解中常见的一种题型，所猜测词汇可以是生词，也可以是熟词新义，还可以是人称代词的指代内容。词义猜测题主要考查考生根据上下文推测词义和语义的能力，突出考查对语境的分析和把握能力。常见的猜词法有： (1)利用上下文语境。猜测任何词义都离不开上下文，所以要借助上下文对需要猜测的词或短语进行合乎逻辑的推测。 (2)利用定义或解释性的线索。阅读文章中的有些生词往往在其后会有对该词进行解释说明的短语或句子，利用它们猜词义较容易。 (3)利用文章的逻辑关系答题。如并列、对比、因果、转折关系等。这些逻辑关系往往通过一些相应的词或短语表达出来，如but, or, however, so, because等。 (4)利用构词法知识答题。熟记一些前缀、后缀所表达的意思，不仅可以扩大词汇量，而且帮助我们猜测词义。第2小题的词义猜测题就是利用第1种解题方法。
（2018·天津·中考真题）In the 13th century. Marco Polo the world known Italian travelled saw many wonderful things in China. One of the things he discovered was money made of paper. People in the West did not have such kind of money until the I5th century. However the Chinese began to use it in the 7th century
Paper was invented by a Chinese man called Cai Lun almost 2,000 years ago. But it was not made in Europe until the year I 100. Four hundred years later, a German discovered that he could make the best paper from trees. After that countries rich in forests, such as Canada Sweden. America. Finland became the most important ones in paper making
Paper can be used in many ways. The common uses include newspapers magazines and books. But do you know that paper can be used for keeping warm? In Finland. the farmers wear paper boots to keep their feet warm in the snow. And even houses can be insulated(使绝缘)from heat or cold with paper.
However. we have to understand that paper still comes from trees now. If we keep on wasting so much paper, there will not be any trees left on the earth some day in the near future. Every day people throw away about 2, 800 tons of paper in our city. It takes 17 trees to make one ton of paper. This means that we are cutting down nearly 48.000 trees every day. The fact is that it takes more than 10 years for a tree to grow.
So we must start saving paper right now. We can use both sides of every piece of paper. We can make useful things out of used paper. We can use china cups instead of paper ones. When shopping, we can use fewer paper bags and reuse them if we have some
In short, we should keep a balance (平衡)between using paper and protecting trees, and do it now before it is too late.
21．When did the Chinese begin to use paper money?
A．In the 5th centum B．In the 6th century
C．In the 7th centum D．In the 15th century
22．Why did Canada become an important country in paper making?
A．Because it was a large country B．Because it had lots of forests
C．Because it was a very rich country D．Because the inventor was from Canada
23．In Finland. paper is used for______.
A．making beds B．reducing waste
C．making umbrellas D．keeping warm
24．According to the passage. how many trees are needed to make one ton of paper?
A．10 B．17. C．2,800 D．48,000
25．Paragraph 5 mainly talks about______
A．how paper boots are made B．how paper was invented
C．how we can save paper D．how we can make useful things

（2018·山东临沂·中考真题）(2018·山东临沂)What was discovered by accident? The answer is penicillin (青霉素). It kills germs. By killing germs, it saves lives. Suppose you are sick. You go to a doctor. She examines you. She says you have a “staph” infection (葡萄球菌感染). She gives you some medicine. You take it. The medicine knocks out the staph. Soon you are well. Before penicillin, this would not happen. Staph was almost sure death.
Everyone wanted a medicine. Laboratories worked day and night. They grew the staph in small dishes. Then they tried to kill it. Nothing worked.
The laboratory dishes had covers on them. They kept things from falling into dishes. Molds (霉菌) were a big worry. They are always in the air. You can’t see them. They’re too small. There are thousands of different molds. Molds can make an experiment (实验) fail. That’s why dishes are covered.
Dr. Alexander Fleming was working to kill the staph germ. He worked for years. One day he took a cover off a dish. He looked inside. There was a thick growth of staph germ. There was also some mold. Then he saw something strange. Where the mold was, there was no growth of staph. This is what Fleming probably thought. “By accident, I found a mold to kill the dreaded staph.”
This is how penicillin was found. But here’s the real miracle (奇迹). There are thousands of kinds of molds. But only one kind can kill staph. The mold must have fallen into the dish a few days before. The cover was probably off only a few seconds (秒). In those few seconds the right mold fell into the right dish. Another man might have thrown the dish away. But Fleming was very careful and smart. He understood what the mold did. How lucky the humans were!

知识精讲
知识点01 invented的用法
【课文详解】When was it invented？它是什么时候发明的
【句型剖析】…was invented …句意为“某物被发明……”，是被动句式。例如：
The abacus was invented in the sixteenth century by the Chinese.
算盘在十六世纪由中国人发明的。
Who was the light bulb invented by？灯泡是由谁发明的？
【拓展】
被动语态的结构是：主语+be done（及物动词的过去分词），be是随人称和时态变化而变化的。
（1）一般现在时的被动语态：am/ is/ are done 例如：
The blackboard is cleaned by the students every class.
黑板每节课都被学生擦干净。
（2）一般过去时的被动语态：was/ were done 例如：
The computer was invented last century.
电脑是上个世纪被发明的。
（3）一般将来时的被动语态：shall/will be done 例如：
A new school will be built in our village next year.
明年一所新的学校将在我们村庄建设。
（4）现在进行时的被动语态：am/is/are being done 例如：
A sports meeting is being held in our school now.
运动会正在我们学校举行。
（5）现在完成时的被动语态：have/has been done 例如：
All of the work has been finished since I came here.
自从我来这里以来，所有的工作都已经完成。
（6）含有情态动词的被动语态：can/may/must/should be done 例如：
Your homework must be handed in after school.
你们的家庭作业必须在放学后交上。
（7）复合宾语的被动语态：原来的句子是“主语＋谓语＋宾语＋宾语补足语”，在变被动语态的时候只能将宾语变为被动语态的主语，宾语补足语变为被动语态的主语补足语。主动语态中宾语补足语是省掉to的不定式时，在被动语态中需要还原to。
They heard her sing an English song at the party.
他们在晚会上听到她唱了一首英语歌。
变为被动语态是：She was heard to sing an English song at the party.
【即学即练】It’s said that tea __________ by accident about five thousand years ago.
A．was invented B．is invented C．will be invented D．were invented
【答案】A
【详解】句意：据说茶是大约5000年前偶然发明的。
考查被动语态。分析句子可知tea和invent之间是被动关系，根据“five thousand years ago.”可知句子应用一般过去时的被动语态：was/were+done，且tea是不可数名词，be动词应用was，故选A。
知识点02 such的用法
【课文详解】Is it really such a great invention? 它真的是如此了不起的一项发明吗？
【句型剖析】such用作形容词，修饰名词。主要用法有：
(1)such＋a(an)＋adj.＋单数可数名词＋that从句。
He got such a bad cold that he coughed day and night.他得了如此重的感冒以至于整日整夜咳嗽。
(2)such＋adj.＋不可数名词＋that从句。

(3)such＋adj.＋名词复数＋that从句。

such (a/an) + adj. + n. 意为＂如此……的(一个)……＂。

【即学即练】It’s ________ a nice invention that I’m wondering who ________ it.
A．so; invented B．such; invented
C．so; did invent D．such; did invent
【答案】B
【详解】句意：这是一项很好的发明，我想知道是谁发明的。
考查such … that …句型和过去时。在“so … that”和“such … that”句型中，so后边可加形容词或副词，而such后要用名词，第一空要修饰的是名词invention，故应用such，A、C选项可排除。第二空根据语境可知，此处在问是谁发明了它，动作发生在过去，故应用动词过去式，故选B。
知识点03 mention的用法
【课文详解】For example, it mentioned that zipper was invented by Whitcomb Judson in 1893.例如,它提到拉链是1893年由惠特科姆·贾德森发明的。

mention doing sth.提到做某事
He mentioned that the food was invented by a Chinese.
他提到这种食物是由一个中国人发明的。
Nobody mentioned it to me.没人向我提过这事。
Whenever I mention having dinner together, he says he's too busy.
无论何时我提起一块儿吃饭,他都说太忙。
【拓展】 “Don't mention it.”常用于口语中,多用作回复他人道谢或道
歉时的答语,意为“不用谢;没关系”
—Thank you very much.多谢你了。
—Don't mention it.不客气。
—I'm sorry to have troubled you.抱歉打扰你了。
—Don't mention it.没关系。
【即学即练】—How could I thank you enough?

考查情景交际。Don’t mention it别客气；No problem没问题；It depends 看情况而定；Of course not当然不会。根据“How could I thank you enough?”可知，对别人的感谢应说不客气，故选A。
知识点04 be used的用法
【课文详解】But at that time, it wasn’t used widely.但在当时，它并没有被广泛使用。
【句型剖析】 sth. be used…是被动语态句式，表示“某物被使用……”。常用如下搭配：

It is used for learning English.＝It is used to learn English. 它是被用来学习英语的。
【即学即练】Last month Tencent Meeting(腾讯会议) ________ to study by us at home.
A．is used B．used C．was used D．was using
【答案】C
【详解】句意：上个月，我们用腾讯会议在家学习。
考查时态和语态。根据“Last month”可知，应该使用一般过去时；根据“Tencent Meeting”和“use”之间构成被动语态，所以应该使用一般过去时被动语态。故选C。
知识点05 It is said that的用法
【课文详解】It is said that a Chinese ruler called Shen Nong was the first to discover tea as a drink.据说,有一位叫作神农的中国统治者最早发现茶可以饮用。
【句型剖析】It is said that…是一个固定搭配的句型，it是形式主语，真正的主语是后面的that从句。它的
思是“据说……”。例如：
It is said that Mary is very happy in London. （主语从句）
= They say that Mary is very happy in London.（宾语从句）
据说玛丽在伦敦是非常幸福的。
【拓展】

知识点06 smell的用法
【课文详解】It produced a nice smell so he tasted the brown water.它散发出一股香味,因此他尝了一下这棕色的水。
【句型剖析】 smell
(1)作名词,意为“气味”,常与of连用,表示“......的气味”。
There's a delicious smell coming from the kitchen.厨房里传来一阵香味。
The air was filled with the smell of flowers.空气中弥漫着花香。

The fish smells delicious.鱼闻起来很香。
Can you smell something?你闻到什么气味了吗?
【归纳】feel,look, sound, smell, taste这五个动词均可作连系动词，后面接形容词作表语,说明主语所处的状态,其意思分别为“感觉”,“看”,“听”,“闻”,“尝起来”。
I'm feeling terrible.我感到难受极了。
The soup tastes delicious.这汤味道不错。
These flowers smell very sweet.这些花闻起来很香。

(2) until用在肯定句中，多与持续性的动词连用。如：stand/wait/stay等，表示主句动作的终止时间。
(3) until可用于否定句中，即not…until…意为“直到……才”，常与非延续性动词连用。如：open/start/leave/arrive等，强调主句动作开始的时间。例如：
The child didn’t go to bed until his father came back.
直到父亲回来，那个孩子才睡觉。

（2017·福建·中考真题）No one knows when the first kite was made. The first record of a kite was more than 2,000 years ago in China. Han Xin, the leader of an army, wanted to bring down a king. He decided to dig a tunnel (隧道）into the king’s palace. He flew a kite over the wall of the palace to make sure the length (长度）of its string (线).In this way, he could determine how long the tunnel should be.His men in the tunnel took the kite string with them. When they reached the end of the string, they knew to dig up.
Kites have been flown in Japan for hundreds of years. In the 1700s, kites were flown in autumn to give thanks for a good harvest. They were also flown to send good wishes to couples who had their first son. Today in Japan, kites are often flown as part of a celebration, such as the beginning of a new year. And kite festivals are held each year in many parts of the country.
Kites have been used for scientific purposes in the western world. In 1752，Benjamin Franklin tied a key to a kite and flew it in a storm to find out that lightening was a form of electricity. In the 1890s，Lawrence Hargrave invented the box kite to test ideas about flight. From 1898 until 1933，the United States Weather Bureau (气象局） used box kites to collect weather data. The Wright brothers also experimented (试验）with kites. What they learnt helped them make the first airplane flight in 1903.

点睛：词义猜测题阅读理解中常见的一种题型，所猜测词汇可以是生词，也可以是熟词新义，还可以是人称代词的指代内容。词义猜测题主要考查考生根据上下文推测词义和语义的能力，突出考查对语境的分析和把握能力。常见的猜词法有： (1)利用上下文语境。猜测任何词义都离不开上下文，所以要借助上下文对需要猜测的词或短语进行合乎逻辑的推测。 (2)利用定义或解释性的线索。阅读文章中的有些生词往往在其后会有对该词进行解释说明的短语或句子，利用它们猜词义较容易。 (3)利用文章的逻辑关系答题。如并列、对比、因果、转折关系等。这些逻辑关系往往通过一些相应的词或短语表达出来，如but, or, however, so, because等。 (4)利用构词法知识答题。熟记一些前缀、后缀所表达的意思，不仅可以扩大词汇量，而且帮助我们猜测词义。第2小题的词义猜测题就是利用第1种解题方法。
（2018·天津·中考真题）In the 13th century. Marco Polo the world known Italian travelled saw many wonderful things in China. One of the things he discovered was money made of paper. People in the West did not have such kind of money until the I5th century. However the Chinese began to use it in the 7th century
Paper was invented by a Chinese man called Cai Lun almost 2,000 years ago. But it was not made in Europe until the year I 100. Four hundred years later, a German discovered that he could make the best paper from trees. After that countries rich in forests, such as Canada Sweden. America. Finland became the most important ones in paper making
Paper can be used in many ways. The common uses include newspapers magazines and books. But do you know that paper can be used for keeping warm? In Finland. the farmers wear paper boots to keep their feet warm in the snow. And even houses can be insulated(使绝缘)from heat or cold with paper.
However. we have to understand that paper still comes from trees now. If we keep on wasting so much paper, there will not be any trees left on the earth some day in the near future. Every day people throw away about 2, 800 tons of paper in our city. It takes 17 trees to make one ton of paper. This means that we are cutting down nearly 48.000 trees every day. The fact is that it takes more than 10 years for a tree to grow.
So we must start saving paper right now. We can use both sides of every piece of paper. We can make useful things out of used paper. We can use china cups instead of paper ones. When shopping, we can use fewer paper bags and reuse them if we have some
In short, we should keep a balance (平衡)between using paper and protecting trees, and do it now before it is too late.
21．When did the Chinese begin to use paper money?
A．In the 5th centum B．In the 6th century
C．In the 7th centum D．In the 15th century
22．Why did Canada become an important country in paper making?
A．Because it was a large country B．Because it had lots of forests
C．Because it was a very rich country D．Because the inventor was from Canada
23．In Finland. paper is used for______.
A．making beds B．reducing waste
C．making umbrellas D．keeping warm
24．According to the passage. how many trees are needed to make one ton of paper?
A．10 B．17. C．2,800 D．48,000
25．Paragraph 5 mainly talks about______
A．how paper boots are made B．how paper was invented
C．how we can save paper D．how we can make useful things

（2018·山东临沂·中考真题）(2018·山东临沂)What was discovered by accident? The answer is penicillin (青霉素). It kills germs. By killing germs, it saves lives. Suppose you are sick. You go to a doctor. She examines you. She says you have a “staph” infection (葡萄球菌感染). She gives you some medicine. You take it. The medicine knocks out the staph. Soon you are well. Before penicillin, this would not happen. Staph was almost sure death.
Everyone wanted a medicine. Laboratories worked day and night. They grew the staph in small dishes. Then they tried to kill it. Nothing worked.
The laboratory dishes had covers on them. They kept things from falling into dishes. Molds (霉菌) were a big worry. They are always in the air. You can’t see them. They’re too small. There are thousands of different molds. Molds can make an experiment (实验) fail. That’s why dishes are covered.
Dr. Alexander Fleming was working to kill the staph germ. He worked for years. One day he took a cover off a dish. He looked inside. There was a thick growth of staph germ. There was also some mold. Then he saw something strange. Where the mold was, there was no growth of staph. This is what Fleming probably thought. “By accident, I found a mold to kill the dreaded staph.”
This is how penicillin was found. But here’s the real miracle (奇迹). There are thousands of kinds of molds. But only one kind can kill staph. The mold must have fallen into the dish a few days before. The cover was probably off only a few seconds (秒). In those few seconds the right mold fell into the right dish. Another man might have thrown the dish away. But Fleming was very careful and smart. He understood what the mold did. How lucky the humans were!
