Part 3 精讲精练
知识点01：原句：We drink water and use water to clean things every day.
我们每天喝水并用水清洗东西。
【语法解析】
(1)考点：use sth. to do sth. 用......做
= do sth. with sth.
例如：We use water to wash hands.我们用水洗手。
=We wash hands with water.
提醒:“主语 + use + sth + to do sth.”表示某人使用某物做某事。谓语动词use的形式要根据主语和时态的变化而变化。动词不定式在句中作目的状语。
(2)【拓展】use和with都有用的意思，use是动词，with是介词，用法不同
“和” I played football with my brother last Sunday.
with的用法: “长着” The boy with a big nose is my brother.
“拥有” I have a new house with a big garden.
“用” Make a sentence with “egg”.
注：句中有谓语动词时，选介词“with”表示用，句中无谓语动词时，选动词“use”。
【牛刀小试】
用所给词的适当形式填空。
1.--There ________ (be) a lot of paper on the desk just now. But now there ________ (be) many paper bags on it. What happened
--Nancy ________ (use) the paper ________ (make) these bags.
2.Mr White (use) the telephone (call) people long long ago.

me
知识点02：原句：We should not waste water. 我们不应该浪费水。
【语法解析】
1.用法·情态动词should表示命令、建议、义务、责任，意为“应当，应该”。
·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。
2.情态动词should引导的几种常见句式：
(1)肯定句结构：主语 + should + 动词原形(+其他).
例如： You should save water. 你(们)应该节约用水。
(2)否定句结构: 主语 + shouldn’t+ 动词原形(+其他).
例如： You shouldn’t waste water. 你(们)不应该浪费水。
(3)一般疑问句结构：Should + 主语 + 动词原形(+其他)
例如： Should we go there tonight 我们今晚应该去那里吗
(4)特殊疑问句结构：特殊疑问词 + should + 主语 + 动词原形(+其他)
例如： What should we do to protect the Earth 我们应该做什么来保护地球

知识点03：原句：Most of our energy comes from coal and oil. 我们的大部分能源来自煤炭和石油。
【语法解析】
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。
【牛刀小试】
根据中文提示完成句子。

知识点04：原句：We should not cut down too many trees. 我们不应该砍伐太多的树木。
【语法解析】
cut down 意为“砍伐,砍掉”, cut的过去式形式还是 cut。

知识点05：原句：易混淆 home, house 和 family 的用法。
【语法解析】
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。
