Unit 10 It’s important to have a healthy lifestyle 知识点讲解与练习

Unit 10
重点难点解析
Section A
1. 【经典习题】
(1) 改为同义句。
He got up early in order that he could catch the first bus.
He got up early _______ ______ _______ catch the first bus.
(2) 改错。
He studies very hard in order that go to college. ____________
【原句再现】In order to be healthy, teenagers need to get enough sleep.
【要点点拨】in order to与in order that 意思相同，均意为“为了”（主语为同一人时）； in order to后跟动词不定式，in order that后跟目的状语从句。
2. 【经典习题】
(1) 选词填空。
It’s necessary ______ (for/of) us to study English well.
(2) 根据所给汉语将下列句子补充完整（每空一词）。
对约翰来说，按时完成这项工作很难。
It was very difficult John ______ the work on time.
【原句再现】I think it’s important for teenagers to talk problems over with someone.
【要点点拨】It is/was +adj. +for sb.+ to do sth.意为“对某人来说做某事是……的”。这样的形容词通常是表示客观情况的词。如：easy, hard, difficult, important, necessary, impossible, interesting等。如：It’s hard for a 10-year-old child to do such a thing.对一个十岁的孩子来说做这样一件事很难。
【拓展延伸】
It + be +adj. +of + sb. + to do sth. 意为“某人做某事是……的”。这些形容词通常是表示主观感情或态度的词。如：good, kind, nice, wise, clever, foolish, right, wrong, careful, careless等。如：It’s very kind of you to think so much of others.你能为别人着想真是太好了。有时这样的句型可以转换成一个用不定式作状语的句子。该句可改为：You are very kind to think so much of others.
3. 【经典习题】
(1) 单项选择。
Don’t look out of the window. Please pay attention?_____?what your teacher says in class. ? A.?to B. / ?C.?of D.?for
(2) 根据句意，用所给单词的适当形式填空。
We should pay more attention to _______ (improve) agriculture.
【原句再现】But in school he doesn’t pay attention in class, and his parents always tell him to try harder.
【要点点拨】pay attention 意为“注意， 集中精力”； pay attention to 中的to是介词，后接v.-ing形式。
Section B
4. 【经典习题】根据所给汉语将下列句子补充完整（每空一词）。
我需要骑自行车去吗？
Do I ______ ______ ______ by bike?
【原句再现】I need to do my homework more carefully.
【要点点拨】need的主语执行need后的动作，这时need后跟动词不定式。如：We need to work harder. 我们需要更加努力地工作。
【拓展延伸】need的主语和need 后的动作存在动宾关系，这时need 后用动名词。如：The car needs repairing.这辆小汽车需要修理。（need doing=need to be done）因此该句可写作The car needs to be repaired.
5.【经典习题】
(1) 改为同义句。
At last the young man gave in.
At last the young man ______ _______.
(2) 根据句意，用所给单词的适当形式填空。
I think you should give up _______ (smoke).
【原句再现】I’ve given up junk food.
【要点点拨】give up 作不及物短语动词，与give in同义，意为“放弃，让步”；作及物短语动词时后接名词或动名词。
6. 【经典习题】 选词填空。
(1) He is _____ (so/such) good a teacher that we all like him.
(2) He is _____ (so/such) a good teacher that we all like him.
(3) There are _____ (so/such) many books in the library.
(4) ______ (So/Such) good books are easy to open our eyes.
【原句再现】And he shouldn’t listen to such loud music.
【要点点拨】（1）so 和such修饰的词不一样，so 用来修饰形容词或副词，such修饰名词。我们可通过冠词的位置来判断。（2）若名词为复数或不可数名词时一般用such，但名词前有many, much, few, little等表示数量多少的词修饰时要用so。

7.【经典习题】根据所给汉语将下列句子补充完整（每空一词）。
我认为你不适合这份工作。
I_______ _______ you ________ right for this job.
【原句再现】I don’t think they understand me as well as we do.
【要点点拨】I think引导的复合句经常用来否定主句，这叫“否定转移”，即否定主句。和汉语表达习惯不同，这一点我们要特别注意。
【拓展延伸】I think/ believe引导的复合句要反问从句。反问部分与从句的助动词、be动词、情态动词和主语保持一致。如：I think he is a good a student, isn’t he?
8.【经典习题】根据所给汉语将下列句子补充完整（每空一词）。
她是个八岁的女孩。
She is _______ ______ girl.
【原句再现】Even a ten-minute nap lunchtime can allow us to work better in the afternoon.
【要点点拨】在英语中，长、宽、高可用复合形容词表达，即“数字+量词（单数）+long/wide/high/old…”，中间为连字符，常用作前置定语。eight-year-old意为“八岁的”，ten-minute意为“十分钟的”；a ten-minute nap意为“十分钟的小憩”。

动词不定式

从方框中选择适当的动词并用其适当形式填空完成句子。

1. It is not an easy thing _________ a language.
2. Nobody knew what _________ next.
3. I heard a girl _________English songs in the next room last night.
4. His wish is _________ a doctor.
5. Would you like something _________?
6. The girl is too tired ______ to the top of the hill on time..
【总结】
本单元的主要语法是动词不定式。动词不定式是非谓语动词，它具有名词的一些特点，因此在句中可作主语、宾语、表语、定语、状语和补语。在英语中，当主语较长时，常用it作形式主语，而将动词不定式放在谓语后边。动词不定式作宾语后面若有补语时，也常用it作形式宾语，把不定式后置；在使役动词及感官动词后，用不带to的不定式作宾补。
