语法精讲——现在完成时
（1）构成：现在完成时由助动词have + 过去分词构成，助动词have 有人称和数的变化。第三人称单数用has，其余用have.
现在完成时的否定式直接在助动词后面加上not、疑问式是把助动词提到主语之前。以study 为例，其否定式、疑问式和简单回答形式如下：
否定式
疑问式
I have not (haven’t) studied….
Have I studied…?
You have not (haven’t) studied….
Have you studied…?
He has not (hasn’t) studied….
Has he studied…?

否定疑问式
简单回答（肯定/否定）
Have I not (Haven’t I) studied…?
Yes, you have. No, you haven’t.
Have you not (Haven’t you) studied…?
Yes, I have. No, I haven’t.
Has he not (Hasn’t he) studied…?
Yes, he has. No, he hasn’t.

（2）用法：
①表示过去发生的动作，但此动作对现在留下了某种影响和结果。
-Would you like to have lunch with me?
-No, I've had it. (现在不饿了)
My daughter has just gone out. 我女儿刚出去。
I’m sure we’ve met before. 我肯定我们以前见过面。
②表示从过去开始的动作，此动作一直持续到现在，有可能到目前停止，也可能继续进行。往往和包括现在在内的表示一段时间的状语连用，如recently, already, just, lately, for…, since…,yet等。
He has taught here since 1981.他自1981年就在这儿教书。（可能还要继续教）
I haven’t seen her for four years.我有四年没见到她了。
We haven’t seen you recently.最近我们没有见到你。
They have been away for two years.他们离开已经两年了。
★注意：
1）since和for的区别
since后接时间点，如1993，last term, yesterday, the time I got there
for后接一段时间，表示“长达多久”，如ten years, a while, two days等。

（3）have been to/ have gone to/ have been in区别
have been to 曾经去过某地，现在不在那地方了（已经回来），后可加次数 如：once ,twice,
three times,表示去过某地几次，也可和just,never ,ever连用。
eg: He has been to China twice.
have gone to 去了…（没回来）
eg: He has gone to school, so he isn’t at home.
have been in （表示在某地呆了多少时间）常与时间状语连用
eg: He has been in China for there years. 他到中国已经有三年了.

（4）现在完成时不能和表示过去的时间状语连用，如yesterday, last year, in 1976, two days ago, just now, when I came in，但可以和already, yet, sometimes, always, often, before, just (放在句中),lately, recently, once, twice, ever, never等连用。例如：
She has already come. 她已经来了。（already 用与肯定句中）
I haven’t read it yet.我还没读过这个。（yet用与疑问句和否定句中）
I have met him before.我从前曾见过他。（before放在句末）
Ma Hong has always been a good student.马红一直是个好学生。
They have never been to Yan’an.他们从未去过延安。
I haven't seen him lately.我近来没看到他。
I have been there twice.我去过那里两次。（twice几次等放在句末表示经历，前面要用一般现在完成时态）

（5）现在完成时和一般过去时的区别
现在完成时和一般过去时都表示在过去完成的动作,但现在完成时强调的是这一动作与现在的关系,如对现在产生的结果或影响等，而一般过去时只表示动作在过去某一时刻发生，不表示和现在的关系。
试比较：
I have lost my new book. 我把新书丢了。（解析：现在还未找到）
I lost my new book yesterday. 我昨天把新书丢了。（解析：昨天丢的，现在找到与否没说明）
（6）延续性动词和非延续性动词的用法
现在完成时表示“动作从过去某个时候开始一直持续到现在”或“在某一时间段内动作一直持续”，谓语动词需要用延续性动词。
现归纳总结一下由非延续性动词（短暂性或瞬间动词）到延续性动词的转换：
buy→have
borrow→keep
die→be dead
come back→be back
leave →be away
begin(start)→be on
arrive→be here
join→be in或 be a member of
eg: He has been in the army for three years.他参军三年了。(be in )
His father has been dead for two years.他父亲去世二年了。(be dead)
The film has been on for ten minutes.电影已开始十分钟了。(be on )
注意:在现在完成时态中,瞬间或短暂性动词不能和for引导的段时间连用。
例：He has bought the book for 3 years.(错) 解析：因为这个瞬间性动词不能和一段时间连用，应改正为：
He has had the book for 3 years.( 解析：用延续性动词have代替buy)
He bought the book 3 years ago.(解析：也可以改为一般过去时，使句子的意思不变)

Important Sentences structures.
1. The soldier came down the stairs-two at a time.
at a time表示“依次，逐一，每次”的意思。
e. g. Take the pills two at a time. 每次服两粒。
She ran up the stairs two at a time. 她一步两阶地跑上楼梯。

2. Outside the main gates of the city stood a huge wooden house.
(1)此句为倒装句，应为A huge horse made of wood stood outside the main gates of the city.
英语中，倒装句表示强调或引起注意。
e. g. The door opened and in came a middle-aged woman. 门开了，进来一位中年妇女，
(2)a huge horse made of wood木制的大马
made of wood为过去分词短语作名词的定语，通常放在这一名词的后面。

3. It's so big that they couldn’t take it with them.
so… that如此……以至于……（中间使用形容词或副词，引导结果状语从句）
e. g. They are so excited that they have forgot to go home. 他们是如此高兴以至于忘记了回家。
It rained so heavily that we had to stay at home. 雨下得如此大，以至于我们不得不呆在家中。
【知识拓展】
(1)so…that…后接肯定句可转换成enough to的结构，变成简单句。
e. g. I am so tall that I can reach the shelf. =I am tall enough to reach the shelf.
(2)so…that…后接否定句可转换成too…to的结构，变成简单句。
e. g. The box was so heavy that he couldn't carry it.=The box was too heavy for him to carry.

4. So the Trojans dragged it into the city with ropes.
drag…with ropes中with表示“以……方式，用……手段”。
e. g. write…with a pen用笔写，…cut…with a knife用刀切……
【知识拓展】with还可解释为“带有，具有”。
e. g. She is a beautiful girl with long hair. 她是一位有着长头发的漂亮女孩。
The lady got on the bus with a baby in her arm. 这位女士手里抱着一个小孩上了公共汽车。
with还可解释为“随着”。
e. g. With the development of computer science, you can know almost everything without going out.
随着计算机科学的发展，你可以不用出门就可以了解天下。

5. No guards stopped them as they opened the main gates.
句中的as解释为“当……时，正值……”。
e. g. As I walking clown the street I noticed a police car.当我在街上走的时候，我看到了一辆警车。
作为从属连词，三者都有“当……的时候”的意思，但用法稍有不同。
(1) as强调主从句动作或事情同时发生或进行，常译为。一边……一边……”，此时as也可换作when或while。
e. g. As (When/While)I was walking along the road, I noticed a police car in front of a shop.
当我沿着公路行走时，我注意到一家商店门口停着一辆警车。
如果表示两个短时间动作或事件同时发生，最常用as(just as)。
e. g. As I sat down on the chair, he gave me a cup of tea. 就在我在椅子上坐下时，他给了我一杯茶。
(2)when和while意为“当……时候”，when可以表示时间点，也可以表示一段时间，谓语动词是终止性和延续性动词都可。而while只表示“在某一段时间里”，因此它引导的句子中的动词必须是延续性的。
e. g. While(When) we were in Beijing, we saw him twice. 我们在北京的时候，看到过他两次。
When the clock struck twelve, all the lights went out.(不能用while)当钟声敲响12点时，所有的灯都熄灭了。
【友情提示】while还可用作并列连词，表对比，意为“而，然而”，when也可作并列连词，表示“恰在此时，
就在这时候”，as引导时间状语从句时还可表示“随着”。
I like P. E. , while she likes music. 我喜欢体育，而她喜欢音乐。
I was about to leave when the phone rang. 我刚要离开，这时电话铃响了。
As the time went on, his theory proved to be true. 随着时间流逝，他的理论证明是正确的。

6. It had returned in the darkness when the citizens were celebrating inside.
return=come back，go back意为“回来，回去”。return还可作“归还”讲，等于give back，所以return不能与back相连。
e. g. Your mother will return in a moment. 你的母亲一会儿就回来，
Do not forget to return my key. 不要忘记还我的钥匙。

7. Now the army entered the city.
Enter=come into，go into意为“进入”，所以enter不能与into相连。
e. g. When the teacher entered the classroom, the students stopped talking. 当老师走进教室时，学生们停止说话。

8. Then the Trojans made sure all the gates of the city were securely locked, and they all went to sleep, including the gate guards.
make sure表示“确信”，go to sleep表示“入睡，睡着”，注意：including在本句中是介词用法。
e. g. All animals including men feed on plants or other animals.
包括人类在内的所有动物都以植物或其他动物为食。
I’ve got three days, holiday including New Year’s Day. 包括元旦在内我有三天假。

9. For ten years, they could not capture the city by fighting.
by在这里解释为“通过”，后跟名词或动名词。
【知识拓展】by还可以在不同的情况下连接宾格、反身代词、时间或地点。
e. g. My wallet was stolen by a thief. 我的钱包被一个小偷偷了。
Can you finish it by yourself? 你能自己完成吗？
By the end of last term, I had learned 800 English words.到上学期期末为止，我已经学会了800个英语单词了。
They were fishing by the river. 他们正在河边钓鱼。

Marco Polo was one of the world’s most famous explorers. He was born in Venice, Italy in 1254. When he was seventeen years old, he went on a trip to Asia that lasted 24 years. Marco Polo’s travel later affected many people.
In 1271, Marco Polo left Venice with his father and uncle and set out for Asia. The purpose of their trip was to meet with Kublai Khan who ruled a large part of Asia. On their way to meet the king at his palace in China, they traveled through much of the Middle East and Central Asia.
In 1275, they finally arrived at the palace of Kublai Khan. Kublai Khan grew to like Marco Polo very much. In fact, he liked him so much that he wanted Marco Polo to work for him. So the king sent Marco Polo to different places in China, India and Myanmar. Marco Polo stayed in China with Kublai Khan for 17 years. Over that time, he collected many jewels (宝石) and lots of gold.
Marco Polo returned to Venice with his father and uncle in 1295. People often went to Marco Polo’s home to hear stories about his travels. He became a great storyteller. Marco Polo was known as “the man with a million stories”. He later met a writer who was crazy about his stories. The writer liked them so much that he wrote a book about Marco Polo’s travels.
The book about Marco Polo’s travels taught Europeans about places in Asia they knew little about. The book also taught people about the geography of Asia. Some of these people were explorers who used the information in Marco Polo’s book on their own journeys. The best known of these explorers was Christopher Columbus.

二、阅读回答问题

You might think that Olympic sportsmen are the healthiest people in the world. It’s true that many are.
However, it’s also true that quite a few Olympic sportsmen had to overcome illnesses early in their lives.
One excellent example is Wilma Rudolph. She competed in track-and-field (田径) events in the 1960 Olympics. She didn’t win just one gold medal. She won three. At the time, people called her “the fastest woman in the world”.
As a young child, Wilma Rudolph could not take part in sports because she had several kinds of serious illnesses. At the age of 4, she even got polio (小儿麻痹症). She lost the use of her left leg, and the doctors said she would never walk again.
The people in Rudolph’s family did everything they could to help her walk again. Wilma and her mother often travelled 100 miles to get medical help for her leg. Four times a day, her brothers and sisters took turns helping her do special exercises for her leg. Amazingly, by the time Rudolph was 9 years old, she was able to walk again. Before long, she started playing basketball and running. In high school, she was a track star, and then she went to the Olympics. Wilma Rudolph left her job as a runner when she was 22 years old. She then became a teacher and track coach.
Wilma Rudolph later did a lot of things for the poor children. Many magazines reported her story to the public. She was a fine example for a lot of people. Her story encouraged many people to work hard to overcome difficulties.
