[答案]

思考：

(1)哪些词可以用来表示“大量的”？

________________________________________________________________________

(2)哪些量词短语去掉of可以充当状语？

________________________________________________________________________

(3)the number of...和a number of...有何不同？

________________________________________________________________________

[答案]

(1)修饰可数名词复数的量词短语有：a (large) number of，(large) numbers of，all kinds of等；

既可修饰可数名词又可修饰不可数名词的短语有：a lot of，lots of，plenty of，a (large) quantity of，(large) quantities of，a pile of，piles of等；

只能修饰不可数名词的短语有：a great deal of，a large amount of，large amounts of等。

另外：“a quantity of / quantities of ＋ n.＋谓语”以及“a large amount of / large amounts of ＋ n.＋谓语”，其中谓语的单复数形式分别与quantity和amount的单复数形式保持一致。

A large quantity of air conditioners has been sold since the summer came.

译：目前的世界人口与1800年相比已经增长了六倍，这个数字现在是70亿！

(1)[population 的句型]

population 的句型小结如下：

The population of...is large / small.(注意：不用many / few，且谓语动词用单数)；

80% of the population here are farmers.(注意：这里population为集合名词，表示“居民”，谓语用复数)；

What's the population of... (注意：不用How many / How much提问)；

...with a population of... 介词短语，“拥有……人口”；

has a population of... 动词短语，“拥有……人口”

英语中倍数的表达方式：

A.“...times ＋ 形容词 / 副词的比较级＋ than...”

B.“...times ＋ as ＋ 形容词 / 副词的原级＋ as...”

C.“...times ＋ the ＋ 名词(如：size，height，weight，length，width 等)＋ of...”

D.“...times ＋ more ＋名词＋ than...”

E.“...times ＋ as many (或 much)＋名词 ＋ as...”

F.“...times ＋ what 从句”

例如：

Line AB is three times longer than Line CD.＝Line AB is four times as long as Line CD.

线段 AB比(线段) CD长三倍。

This table is three times as long as that one.

这张桌子是那张桌子的三倍长。

今年我们生产的棉花比十年前多了一倍。(汉语中的多一倍实际上指两倍一样多。)

The length of the road is four times what it was three years ago.

这条路的长度是三年前的四倍。

选择填空：

①I like this sweater better than that one，but it cost 　　　　　　(three times as much / three times as many).

②That company pays me three times 　　　　　　(than/what) I earned and hopes that I will go there to work.

[答案与解析]

①three times as much。句尾省略了as that one。根据倍数表达法，且钱为不可数名词，可知应填three times as much。

②what。倍数表达方式“...times＋what从句”，故填what。

思考：常用的倍数的表达方式还有哪些？

________________________________________________________________________

[答案]

倍数还可以用以下方式表达：

1)“...times＋up / on / over...”；

2)“...＋by ＋...times”；

3)“...times ＋ compared with ＋被比较对象”；

4)“...times ＋ that of ＋ 被比较对象”。

3.Ms Lin suggested we should cut back on the quantity of things we produce in order to save the environment.(P23，L40­41)

译：林女士建议为了保护环境我们应该削减我们所生产的东西的数量。

[suggest后接从句的用法]

与suggest (建议)相关的从句用“(should)＋动词原形”的形式充当谓语。

例如：

I suggest that he (should) not spend too much time playing computer games.

我建议他不要花太多时间玩电游。

My suggestion that he (should) not spend too much time playing computer games has been accepted.

我建议他不要花太多时间玩电游，他接受了。

It is suggested that he (should) be sent to the rural areas to gain experience of managing a farm.有人建议把他送到农村地区去获取经营农场的经验。

His suggestion was that we (should) wait for another two days.他的建议是，我们再等两天。

中译英：

　　　　　　 that we (should) set up a reading club.

有人建议我们成立一个读书俱乐部。

[答案]

It is suggested

思考：

a.suggest除了表示“建议”外，还有什么用法？

________________________________________________________________________

b.像suggest这样有双重用法的词，在高中英语中还有哪个？

________________________________________________________________________

c.英语中表示“建议”“命令”“要求”“提议”的词有哪些？

________________________________________________________________________

[答案]

a.suggest还可表示“显示”“说明”“暗示”。这时其用法与普通动词用法一致。

例如：What he said suggested that he was satisfied with our homework.

他的话说明他对我们的家庭作业(的完成情况)很满意。

b.insist也有两个词义，一是表示“坚持要求……”；一是表示“坚持认为(某一事实)”，这里其后的宾语从句不用(should)＋动词原形的形式。

例如：He insisted that he hadn't taken your book.他坚持认为他没有拿你的书。

c.英语中常见的表示“建议”“命令”“要求”“提议”的词有：suggest / suggestion， advise / advice， order， insist， propose / proposal， recommend / recommendation， require / requirement， demand， request等。

3.The results of the medical check­up suggested that my father 　　　　　　(be) in poor health， so the doctor suggested that he 　　　　　　(give) up smoking and take more exercise.

4.This river is three times the 　　　　　　(deep) of that one.

[答案与解析]

1.the。句意：和去年相比，今年出国留学的学生人数增长了20%。短语the number of“……的数目”谓语动词用单数形式。

2.that。考查比较级中that用法。当比较级than后面内容与前文重复时，可以用that代替相同内容。

3.was； (should) give。考查固定结构。suggest当“暗示，表明”讲时，后面宾语从句用陈述语气；当“建议”讲时，用(should)＋动词原形的虚拟语气。句意：医疗检查的结果表明我的父亲健康状况很差，所以医生建议他应该戒烟，多锻炼。第一个suggest当“表明”讲，用陈述语气，用was；第二个suggest当“建议”讲，用should＋ give up，should可省略。

4.depth。考查倍数的表达方式。句意：这条河是那条河的三倍深。此处应运用“倍数＋the＋名词＋of”结构。
