10、ng faster and faster. 当主语是表示“人口的百分之几、几分之几”时，谓语动词用复数形式。 e.g.About seventy percent of the population in China are farmers. 有时population可用作可数名词，其前可用不定冠词。 e.g.China has a population of about 1.3 billion. =There is a population of about 1.3 billion in China.表示人口的“多”或“少”,不用“much”或“little”,而要用“large”或“smal
11、l”。 e.g.India has a large population.

13、ave left there. 他们当中约有三百万人离开了那儿。 当不与具体数字连用，而是表示不确定的泛指数时，则不仅要用复数，而且要后接介词of，然后才能接名词。 e.g.A careless mistake cost the company millions of pounds. 一个粗心的错误使公司蒙受数百镑的损失。 拓展：与million有相同用法的数词还有：hundred（百）, thousand（千）, billion（十亿）。本节课主要学习形容词的比较级的规则变化及用法。 （1）规则变化： 类别 构成方法 原级 比较级 单音节词和少数双音节词 一般直接加-erlongtalllo

16、taller of the twins. 表示“越来越”，用比较级重叠结构，即“比较级+and+比较级”，多音节词和部分双音节词时用“more and more+形容词原级”。 e.g.Its getting warmer and warmer in spring.Our home town is becoming more and more beautiful. 表示“越就越”时，用“the+比较级，the+比较级”结构。 e.g.The busier he is, the happier he feels.

18、三者以上的人或物进行比较时，用最高级形式。形容词最高级前必须加定冠词the，句末常跟一个in/of短语来表示范围。（of表示同范围，in表示不同范围） e.g.He is the strongest of the three boys.Shanghai is the biggest city in China. 表示在三者或三者以上的人或物进行选择时，用“Which/Who is+the+最高级，A，B or C？”结构。 e.g.Which city is the most beautiful, Beijing, Shanghai or Fuzhou？ 表示“最的之一”时，用“one of
19、the+形容词最高级”结构，该形容词后面的名词要用复数形式。 e.g.Zhou Jielun is one of the most popular singers. 形容词最高级前面可以加序数词，表示“第几最”。 e.g.The Changjiang River is the first longest river in China. 形容词最高级前面可以有物主代词，指示代词，名词所有格等修饰，但此时不能再用定冠词the。 e.g.This is our last lesson today. 形容词比较级结构可以表示最高级含义。 e.g.Li Lei is the tallest studen
20、t in his class.=Li Lei is taller than any other student in his class.=Li Lei is taller than the other students in his class.=Li Lei is taller than anyone else in his class.Module 5 Lao She Teahouse重点知识讲解 1offer （1）做动词，意思是“提供；提议；提出”。常用的搭配： offer sth. e.g.Many people willingly offered their blood. 很多人

23、 sb.”结构。 你有一支钢笔，请给我看看。 You have a new pen, please show it to me. You have a new pen, please show me it. 意为“带领”，常构成短语show sb. to, 意为“带某人去”；show sb. around，意为“带某人参观”。e.g.Please show me to your school. 请带我到你们学校去。 Uncle Wang is going to show us around his farm. show+ that从句 看出或者显示说明 e.g.Your homework sh

25、if引导的条件状语从句。if是连词，意思是“如果；若”。主句是you can enjoy them at the teahouse，从句是you like the Beijing opera, traditional music or magic shows。 思考：如何使用if条件状语从句呢？ 在句中做条件状语的从句是条件状语从句，可以放在句首，也可以放在句末。常见的if条件状语从句表示在某条件下，某事很可能发生。紧跟在if后面的句子是从句。 e.g.If you ask him，he will help you 另外，if从句还表示不可实现的条件或根本不可能存在的条件，也就是一种虚拟的条件
26、或假设。从句多用一般过去时或过去完成时，表示对现在或过去的一种假设。 e.g.If I were you，I would invite him to the party if：当“是否”讲时，引导宾语从句。 e.g.I dont know if he will be free tomorrow.注意：if引导的条件状语从句中，如果主句使用的是一般将来时，或含有情态动词的句子或祈使句，从句通常用一般现在时。 e.g.If it rains tomorrow, we will not go to the zoo.如果明天下雨的话，我们将不去动物园。 If he comes, let me know
27、.如果他来，让我知道。 （从句用一般现在时，主句是祈使句）难点知识讲解：动词不定式（I） （1）动词不定式的含义 We decided to stay for a cup of tea.I tried to understand the words.I want to go to the teahouse.这三个句子中使用了decide to do sth.，want to do sth.，try to do sth.的表达方式，即行为动词后的动词都采用了“to+动词原形”的结构。我们把这种结构称为动词不定式。其否定形式是“not to do”。 （2）动词不定式作宾语的用法 常见的后面接“t
28、o十动词原形”作宾语的动词有：plan, decide, hope, want, agree, offer, try, like, love等。口诀（接不定式作宾语的动词）想要学习 早打算（ want learn plan）快准备 有希望（ prepare hope wish expect）同意否 供选择（agree offer choose）决定了 已答应（decide determine promise）尽力去 着手做（manage undertake）别拒绝 别假装（refuse pretend）失败不是属于你（fail）e.g.Tom refused to lend me his pe
29、n.We hope to get there before dark.The girl decided to do it herself.注意：某些及物动词可用-ing也可用动词不定式作宾语，但意义不同的有：Module 6 Animals in danger1.形容词变成副词的规律。 一般在形容词的词尾加-ly可以变成副词。例如：quickquickly, slowslowly, loudloudly, suddensuddenly等。 特殊情况： 构成方法 例子 一些以“辅音字母+y”结尾的形容词，要把y改为i再加-ly。 happyhappily,angryangrily有些以-ble或
30、-le结尾的形容词，去掉e加-y。 possiblepossiblyterribleterribly少数以e结尾的形容词，要去掉e再加-ly。 但绝大多数以e结尾的形容词仍然直接加-ly。 truetrulypolitepolitelywidewidely以-l结尾的形容词变为副词时仍然要在词尾加-ly，而不是只加-y。除非是以-ll结尾的才在词尾只加-y。 carefulcarefullyusefulusefullyfullfully温馨提示：副词修饰行为动词这一点。如： He is very _(careful).He does everything _(carefully)第一句中是作表
31、语，用形容词careful；第二句中修饰行为动词does用副词carefully。 常考的形容词和副词辨析有：hard 努力hardly 几乎不；late迟的，晚的lately 近来；deep 深deeply 深深地；near靠近nearly 差不多；wide 宽widely 广泛地；high高的highly 高度地；close 靠近的closely 密切地； free免费的freely 自由地。 典例剖析： Tom studies _ but his sister _ studies.Ahard，hardBhardly，hardlyChard，hardlyDhardly，hard4-ing形
32、容词和-ed形容词的区别。 -ing形容词 -ed形容词 例句 interesting有趣的 interested感兴趣的 I have an interesting book.He is interested in science.exciting令人兴奋的 excited感到兴奋的 Have you heard of the exciting news？ We are excited about the traveling.moving令人感动的 moved受感动的 Titanic is a moving film.We are moved by Hong Zhanhui deeply.表
33、示主动意义，多指事物对人的影响，一般修饰事物。 表示被动意义，多指人对事物的感受，主语一般是人，常用于“sb.+-ed形容词+介词”结构。 We are all interested in the interesting story.M7 A famous story1. a girl called Alice. 此处called为过去分词，修饰girl，放在名词之后。相当于named.2.fall down 跌倒，掉下 fall behind 跟不上，落在后面 fall into 落入中 fall off 从上掉下来 fall back 退回fall asleep 入睡 fall ill 生

36、strange作后置定语，修饰不定代词nothing。在英语中，当形容修饰不定代词somethinganythingnothingeverything等时，形容词必须放在不定代词后面，作后置定语。11. hear sb do sth 听到sb 做sth(此处是省略to的动词不定式作宾语补足语，类似的有makelethavehelp sb do sth 等) hear sb doing sth 听到sb 正在做sthEg：I heard her play the piano in the next room just now.

40、过去时，过去进行时等)；l 当主句为过去时态时，宾语从句表示一种客观真理、事实时，用一般现在时。Eg：I know (that) you met him yesterday. He asked if I would come. I dont understand what you say. He said there were no classes yesterday afternoon.
