Unit 7 Protect the Earth
语法梳理:不可数名词与情态动词should精讲精练(含答案)
不可数名词
解析:根据表示的事物性质的不同,可将名词分为可数名词和不可数名词。
可数名词可以计数,有单复数的区分。而不可数名词是不可以直接计数的名词,没有复数形式。当不可数名词作主语时,谓语动词要用第三人称单数形式。例如:
The soup is too hot. 汤太烫了。
不可数名词可以分为物质名词和抽象名词。
物质名词举例: water, coal, oil, rice 等。
抽象名词举例:homework, time, housework,news等。
*有一些不可数名词表示泛指时是不可数,表示种类时是可数,但含义大多数不发生变化。例如:fruit-fruits, food-foods。一般我们使用它们的不可数形式。
有的单词有时可数,有时不可数,例如 chicken 和 fish
作为餐桌上的鸡肉、鱼肉时,是不可数名词;
作为动物鸡、鱼时,是可数名词(同时注意 fish 作为可数名词时,单复数同形,只有在强调不同种类的鱼时,才用 fishes)。
不可数名词前面可以用some, any, a lot of等修饰,但不能用many修饰。
不可数名词前还可以用“数词+单位词+of”表示数量。例如:a cup of tea 一杯茶。
对不可数名词的量提问时用 how much;对不可数名词前的“单位词”提问时,疑问词用how many。例如:How much tea is there on the table 桌上有多少茶
How many cups of tea are there on the table 桌上有几杯茶

·情态动词should与动词原形搭配使用,
·其否定形式是should not,should not可缩写为shouldn’t。
易错点提醒:should为情态动词,没有人称和数的变化。
情态动词should引导的几种常见句式:

重难点讲解
We drink water and use water to clean things every day.
我们每天喝水并用水清洗东西。
解析:use…to do sth意为“用……做某事”,带to的动词不定式在此处作状语,表示目的。
句中的 use water to clean things还可以用含有with 的结构来表达,即clean things with water。
【例句】We use the old newspapers to make boxes.我们用旧报纸来制作盒子。
【练习】用所给词的适当形式填空。
You can use it (carry) big things.
【答案】to carry
We should not waste water. 我们不应该浪费水。
解析:should 是情态动词,意为“应该,应当”
通常用来表示现在或将来的责任或义务,没有人称或数的变化,后接动词原形
其否定形式是在后面加 not,即 should not,也可缩写为shouldn't。
【例句】(1) Everyone should protect the Earth and keep it clean.
每个人都应该保护地球,并使它保持干净。
(2) You shouldn't drive after drinking. 你不应该酒后驾车。
【练习】单项选择。
( )(1) We smoke in the restaurant.
A. should B. shouldn't C. can
( )(2) You do your homework in time.
A. shouldn't B. can’t C. should
【答案】(1) B (2) C
Most of our energy comes from coal and oil. 我们的大部分能源来自煤炭和石油。
解析:most of 表示“大部分的”,其后接可数名词复数或不可数名词。
当“most of+名词”作主语时,谓语动词的形式由of后名词的单复数所决定。
此句中的 energy 是不可数名词,意为“能源”,谓语动词用其第三人称单数形式 comes。
【例句】(1) Most of my friends live abroad.我的大部分朋友住在国外。
(2) Solving the energy problem is very important.
解决能源问题是很重要的。
【练习】根据中文提示完成句子。
(1) 地球上有很多能源吗
there energy on Earth

It's warm the time in spring here.
【答案】(1) Is, much (2) most of
We should not cut down too many trees. 我们不应该砍伐太多的树木。
解析:cut down 意为“砍伐,砍掉”, cut的过去式形式还是 cut。
【例句】They cut down the big tree.他们砍掉了那棵大树。
【练习】单项选择。
( ) Please use a sharp axe(斧) the wood.
A. to cut down B. cut down C. to cutting down
【答案】A
Let’s make a poster and tell them about it.
让我们制作一张海报并告诉他们关于这方面的事情。
解析:tell sb about sth意为“告诉某人关于某事”。
【例句】John told everyone about the secret.
约翰把这个秘密告诉了所有人。
【练习】单项选择。
( ) Let me tell you how to reuse old cloth(布料).
A. to B. and C. about
【答案】C
易错易混全解
易混淆 many 与 much 的用法。
【例题】单项选择。
( )(1) We shouldn't use plastic.
A. too many B. too much C. so many
( )(2) We shouldn't use plastic bags.
A. so much B. too much C. too many
【答案】(1) B (2) C
点拨:many 和 much 都表示“很多”,用来修饰名词。many用来修饰可数名词,后接可数名词的复数形式;much用来修饰不可数名词。
第(1)小题,设空处后的 plastic 是不可数名词,要用too much 修饰,故选 B。第(2)小题,设空处后的 plastic bags 是可数名词复数,要用too many修饰,故选C。
易错用 useful前的不定冠词。
【例题】选词填空。
I've got (a/an) useful book.
【答案】a
点拨:不定冠词a与an的用法区别在于:a用于读音以辅音音素开头的单词前, an用于读音以元音音素开头的单词前。此题设空处后的 useful 的发音是以辅音音素/ju /开头的,故填a。
易混淆 home, house 和 family 的用法。
【例题】单项选择。
( ) All my like watching films.
A. home B. house C. family
【答案】C
点拨:home主要指家庭成员所居住的环境与房屋;house 主要指家庭成员所居住的建筑物;family主要指家庭成员,一般不涉及居住的房屋,当 family作整体概念的“家庭”讲时是单数名词,而当作“家人”讲时是复数名词。此题的句意为“我们全家人都喜欢看电影。”要用family表示“家人”,故选C。
We should not cut down too many trees because trees help keep the air clean. (P69)
We use plastic to make bags and bottles, but too much plastic is bad for Earth.
太多
