一 复合不定代词
不指明代替任何特定名词或形容词的代词叫不定代词，它们有some, any, much, many等以及由every-, some-, any-, no-加上-thing, -body, -one构成的复合不定代词。下面我们主要学习有关复合不定代词的内容。

2. 复合不定代词作主语时，谓语动词常用单数形式。如：

频度副词表示事情发生的频率。常见的频度副词有always, sometimes, hardly ever, usually, often, never等。
◆常见的频度副词的频率大小如图所示：

◆ 频度副词的位置: 频度副词通常放在实义动词之前，系动词、助动词或情态动词之后，但有些频度副词如sometimes，often等位置比较灵活，还可以放在句首或句尾。如：
David usually gets home at about this time. 
My sister doesn't always read in the library.
(注意：always 与not连用，表示部分否定，意为“并非总是”。若要表示全部否定，应用never。)
My father sometimes / often works at the weekend.
Sometimes / Often my father works at the weekend.
My father works at the weekend sometimes / often.
◆ 当对频度副词及表示事件发生频率的短语提问时，常用how often，意为“多久一次”。如：

  →How often does Bill go to the cinema?

三 形容词、副词的原级和比较级
大多数形容词和副词有三个等级：原级、比较级和最高级。本单元我们主要学习形容词、副词的原级和比较级的构成及其用法。
◆ 原级
形容词、副词的原级即原形。
1. 原级可用于句型“主语+ be / 行为动词+ as + 形容词 / 副词原形+ as +比较对象.”，该句型表示两者在某一方面相同。当表示一方在某一方面不及另一方时，常用句型“主语+ be + not + as / so + 形容词原形+ as +比较对象.”或“主语+ don't / doesn't / didn't + 行为动词原形+ as / so +副词原形+ as +比较对象.”。如：
This dress is as beautiful as that one.
Tom isn't as / so tall as me.
2. 原级前可用very，quite，too等副词修饰。如：
I'm very hungry.
◆ 比较级构成
一．形容词比较级的变化
1. 规则变化
（1）在形容词后直接加-er。如：tall-----taller，short------shorter等。
（2）以不发音的字母e结尾的只需在末尾加-r。如：nice------nicer，large-------larger等。
（3）以“辅音字母+y”结尾的形容词，要先把y变成i，然后再加-er。
如：heavy------heavier，happy------happier等。
（4）若以重读闭音节结尾且只有一个辅音字母，先双写这个辅音字母，然后再加-er。
如：fat------fatter，hot------hotter等。
（5）多音节和部分双音节的形容词，可不是在末尾变化，而是在前面加more。
如：careful-----more careful，athletic-------more athletic等。
2. 不规则变化
good /well------better bad /badly-------worse many /much-------more few /little------less
二．形容词比较级的用法
在描述单个的某人或某物所具有的特征时，需要用形容词原级形式，当把两者进行比较时，就用比较级，常见的表示这类用法的句型有：
1.“A+be+比较级+than+B”表示“A在某方面超过B”。如：
This book is dearer than that one. 这本书比那本书贵
2.“Which /Who(se)+be+比较级, A or B?”意思是“A和B，哪个更…….”。如：
Which is bigger, the sun or the earth? 太阳和地球，哪个更大？
Whose bag is heavier, yours or mine? 谁的包重些，你的还是我的？
3.“A+be+the+比较级+of the two(……)”意思是“A是两者中较…….的一个。”这时前面一定要加the，表示特指。如：
Lily is the taller of the twins. 莉莉是双胞胎中个子较高的那个。
三．常与比较级连用的词
1. 前面可以加上a little，a lot，much，even，still等程度副词作修饰语。如：
She is much more careful than her brother. 她比她哥哥细心多了。
2. 前面还可以加表示数量、倍数的修饰语。如：
My brother is two years older than I. 我哥哥比我大两岁。
This room is twice bigger than that one. 这个房间比那个房间大两倍。

四 形容词、副词的最高级
当三者或三者以上(人或物)进行比较，其中有一个在某一方面超过其他几个时用最高级，最高级表示“最……”。
◆构成
1.形容词最高级的构成
（1）规则变化
1)在形容词后直接加-est，如：tall-----tallest，short-----shortest 等。
2)以不发音的字母e结尾的只需在末尾加-est，如：nice-----nestest，large------largest等。
3)以辅音字母+y结尾的形容词，要先把y变成i，然后再加-est，如：heavy-----heaviest，happy-----happiest。
4)若以重读闭音节结尾且末尾只有一个辅音字母，先双写这个辅音字母，然后再加-est， 如：fat----fattest， hot-----hottest等。
5)多音节和部分双音节的形容词，可不是在末尾变化，而是在前面加most。如：careful -----most careful athletic------most athletic等。
（2）不规则变化
good /well-----best bad /badly -------worst many /much -------most little /few ------least
2.形容词最高级的用法
当需要对三者或三者以上的人事物进行比较，表示“最………”的含义时，需要用形容词的最高级。在使用最高级时应注意以下几点：
（1）最高级通常要加定冠词，但前面有物主代词、名词所有格等修饰时，则不用定冠词。如：
Jim is Mike’s best friend. 吉姆是迈克最好的朋友。
（2）常与介词in或of引导的短语连用。in后面是比较范围，of后面是比较对象。如：
She is the oldest of these children. 她是这些孩子中年龄最大的。
Lily is the youngest in her class. 莉莉在她班里年龄最小。
（3）最高级前可用序数词，二者共同修饰后面的名词，其结构为：the+序数词+形容词最高级+名词单数。如：The Yellow River is the second longest river in China . 黄河是中国的第二长的河。
（4）最高级前可加one of ，即：one of +the +形容词最高级+名词复数，表示最……..的之一。如：
He is one of the smartest students in this school. 他是这所学校中最聪明的学生之一
（5）有时被最高级修饰的名词前还可用不定冠词，但这时不含比较的意思，只是表示非常，很。如：
Their performance was a greatest success. 他们的演出非常成功。

五 初识不定式
不定式有两种形式：一种是带to的不定式，即to + 动词原形；一种是不带to的不定式，即动词原形。不定式(短语)在句中不能单独用作谓语，但可以用作主语、表语、宾语、定语、状语等。在本单元我们主要学习带to的不定式(短语)作宾语的用法。
◆带to的不定式(短语)在句中可作宾语。如：
Tina hopes to arrive at about 4 p.m.
Peter expects to travel to Hong Kong.
◆目前学过的可跟带to的不定式（短语）作宾语的动词有like, love, want, hope, wish, expect, decide, try, plan, forget, remember, start, help, need, learn, seem等。

◆ 结构：be going to后接动词原形，其中be根据主语的变化而变化。如：
I am going to buy a bike next year.
The wind is blowing hard. It's going to rain.
They are going to visit the museum tomorrow.
◆ 否定式及疑问式：be going to结构的否定式是在be后面加not；疑问式是将be提到主语前面。如：
Bob isn't going to drive to Beijing tomorrow morning.
The Browns are going to move to their new house this weekend. → Are the Browns going to move to their new house this weekend? 
【温馨提示】
当be going to结构用于含时间状语从句的复合句中时，主句用 be going to结构，从句常用一般现在时表示将来。如：

八 可数名词和不可数名词
名词分为可数名词和不可数名词两大类。大多数名词为可数名词，有单复数之分，而不可数名词没有复数形式。
1.可数名词变复数分为规则变化和不规则变化两种：
(1)规则变化
1)一般名词变复数时，直接加-s。如：book----books pen-----pens hat-----hats
2)以字母-s，-x，-sh，-ch结尾的名词，在词尾加-es。如：
bus----buses glass----glasses class-----classes box------boxes fox------foxes watch------watches brush-----brushes dish------dishes wish------wishes
3)以-f，-fe结尾的，把f，fe变为v，再加-es。如：
leaf-----leaves half-----halves self-----selves wife-----wives knife-----knives wolf------wolves shelf------shelves thief------thieves life------lives
可把以上九个以-f，-fe结尾的词串成这样的一句口诀记忆：
树叶(leaf)半数(half)自己(self)黄，妻子(wife)拿刀(knife)去杀狼(wolf)，架(shelf)后小偷(thief)逃命(life)忙。
注意：有些词虽然也是以-f结尾，但复数形式却是直接加-s。如：
roof(屋顶)-----roofs belief(信仰)------beliefs proof(证据)------proofs handkerchief(手帕)------handkerchiefs
4)以“辅音字母+-y”结尾的，先变y为i，再加-es。如：family-----families lady-----ladies city------cities
5)以-o结尾的，有时加-es，有时加-s
加-es的可串成口诀记忆： 黑人(Negro)英雄(hero)爱吃西红柿(tomato)和土豆(potato)。
注意：千克的复数形式为kilos。如：I weight 52 kilos. 我的体重是52公斤。
(2)不规则变化
有些名词变复数时属于不规则变化，这种变化是通过改变单词中的某个字母或在词尾加后缀构成的。
1)该a为e型：
man------men woman------women Englishman------Englishmen Englishwoman-------Englishwomen Frenchman-------Frenchmen Frenchwoman------Frenchwomen policeman------policemen policewoman------policewomen
2)该oo为ee型：foot------feet tooth------teeth goose------geese
3)在词尾加-ren。如：child------children
4)其他特殊变化。如：mouse-----mice
2.不可数名词及其量的表示法：
(1)不可数名词包括：
物质名称：食物：bread meat rice cheese fish beef
饮料：milk water cola coffee wine tea
自然物质：air soil sand wood
抽象名词：情感：love peace friendship joy happiness
概念：exercise knowledge energy population
学科：math geography physics chemistry
(2)不可数名词的量的表示法：
如果要表达出不可数名词具体的数量，可以通过“计量词+of+不可数名词”来表示。若想表达量的复数概念，只需把计量词变为复数形式即可。如：
a piece of paper 一张纸 ten pieces of paper 十张纸 a cup of coffee 一杯咖啡 two cups of coffee 两杯咖啡
a piece of news 一条消息 two pieces of news 两条消息 a drop of ink 一滴墨水 three drops of ink三滴墨水
a bottle of milk 一瓶牛奶 five bottles of milk 五瓶牛奶 a bag of rice 一袋大米 twenty bags of rice 二十袋大米
(3)可数名词与不可数名词的区别及其应用：
1)可数名词单数可用修饰，复数可用基数词及some，any，few，a few，many，a lot of等来修饰。
不可数名词不能直接用数词修饰，需用“基数词+计量词+of”结构，也可用some，any，little，a little，much a lot of来修饰。
2)用how many询问可数名词数量的多少。用how much询问不可数名词数量的多少。
3)单个单数名词作主语，谓语动词用单数；多个单数名词或复数名词作主语，谓语动词要用复数。
不可数名词作主语，谓语动词用单数。但当其前有“基数词+计量词+of”时，谓语动词依计量词而定。
特别提醒：有些名词既是可数名词，又是不可数名词，但两种情况下的含义是不同的。如fish作可数名词表

九 再识情态动词can
七年级下册我们已经学过情态动词can表示能力。本单元我们主要学习情态动词can表示请求和可能性。
◆can表示请求时，可用来发出邀请，相当于Would you like to ...?，这时答语比较灵活。如果接受邀请，答语可用Sure, it sounds great. / Sure, I'd love to.等；如果拒绝邀请，答语可用Sorry, I must / have to ... / I'm afraid not. / Sorry, I can't. / I'd love to, but ...等。如：
—Can you go to the zoo with me?
—Sure, I'd love to. / Sorry, I have to study for my tests.
◆can还可表示一种“可能性”，可用来询问打听第三方能否参加某项活动。其句型为Can he / she / they ...?，这类问句的肯定答语为Yes, he / she / they can.；否定答语为No, he / she / they can't. / No, he / she is / they are not available.等。如：

十 if引导的条件状语从句
含有if引导的条件状语从句的复合句表示假如有从句动作的发生，就会有主句动作的发生。
★ 通常情况下，如果主句用一般将来时，if引导的条件状语从句用一般现在时。如：
If he misses the last bus, he'll have to walk home.
★ 如果主句是祈使句或者主句的谓语部分含有情态动词，if引导的条件状语从句也常用一般现在时。如：
If anyone calls, tell them I'm very busy.
【链接】本单元我们还学了连词unless，可意为“除非；如果不”，通常可以和if ... not互换使用。
He won't go to sleep unless you tell him a story. 
=He won't go to sleep if you don't tell him a story.
