八年级上Unit 2课文疑难解析

发布时间:2017-12-20 编辑:互联网 手机版

  1. It might be because you have too much yin. 这可能是因为你有太多的“阴”。

  问:might是may的过去式,这句话说的是过去吗?be动词后面怎么不用形容词或名词作表语呢?

  答:might是may的过去式。但是本句中的might并不表示过去。只是表示口气的缓和、委婉。can的过去式could也有这种用法。例如:

  -Who can it be? 可能是谁呢?

  -It might be Mr Yang. 可能是杨先生。

  -Could you lend me your bike?你能把你的自行车借给我吗?

  -Yes, I can. 可以。

  I could talk about Chinese names. 我可以谈谈中国的姓名。

  七年级的时候,我们多认为be动词后面接的表语通常为名词、形容词等。能做表语的例子还很多,这里我就不说了。如介词短语就可以做表语。看例子:

  All the students are on the playground. 所有的同学都在操场上。

  一个完整的句子也可以做表语。例如:

  The fact is that he isn't Japanese. 事实上他不是日本人。

这样看来because引起的这个句子做表语就不稀奇了。你来说一个句子试试:

这就是他昨天迟到的原因。

你不能说:This is because he was late for school.

你该说:This is why he was late for school. 哈哈!why的从句不也做了表语吗?

2. Eating Dangshen and Huangqi herbs is also good for this. 吃一些党参和黄芪也对此有好处。

问:又不是“正在吃”,用eating干吗?;“对……有好处”用be good to对吗?

答:eating这种V-ing形式确实有“进行”的意思,尤其是与be动词在一起的时候(这是现在进行时态的基本形式)。

你可能不知道,V-ing形式还具有名词的特征。它是把那个动词名词化了。例如:

Getting up early is good for your health. 早起对你的健康有益。

再如:

Seeing is believing. 眼见为实。

从例子中还可以看出,以V-ing形式做主语,总是与单数的谓语动词对应。

这种V-ing形式既然具有名词词性,当然就可以做宾语了。这次由你来做一道题。汉语是:乔总是喜欢踢足球。

Joe always likes playing football. (对了!)

这个V-ing和前面的用法一样。

be good for...意思是“对……有好处”。有时我们会读到be good to...,但是它多半是表示“对某人善良、友好”。如果你看到的是be good at...,那就是“擅长做某事”的意思了。

读下面的句子:

My father is good to me.

Her help is good for me.

I'm good at English.

翻译出来不成问题吧!

课本重点与中考考点“新密接触”

  【课本重点】The students are listening______their teacher very carefully.

  A. to B. on C. for D. at

  【解析】listen是不及物动词,后不能直接接宾语,后接宾语时,要加上介词to。故该题选A。

  【课本重点】What's the matter?

  【中考考点】-______.

  -I have a headache, doctor.

  A. What's the trouble?

  B. What worry with you?

  C. What's your name?

  【解析】当看出某人有不舒服的情况时,可以亲切地询问对方What's wrong (with you)?/What's the matter (with you)?/What's the trouble (with you)?,故该题应选A。

  【课本重点】He shouldn't eat anything for 24 hours.

  【中考考点】I'm hungry. I would like to have______nice to eat.

  A. any B. anything C. something D. some

  【解析】any和some用作形容词时,不能用来修饰形容词。anything一般用于疑问句或否定句,something一般用于肯定句。当形容词修饰不定代词时须放在不定代词之后。因此,该题只能选C。

  【课本重点】It will make you sick.

  【中考考点】下面句子的A、B、C、D中有一处错误,请找出并改正,但不能改变句子的原意。错处的序号和改正的部分,填写在左边的横线上。

  His words(A) at(B)the meeting yesterday made(C) all of us very angrily(D).

  【解析】make sb. / sth. +形容词表示“使……处于……状态”,形容词在句中作宾语补足语,对宾语作补充说明。angrily是副词,其形容词形式是angry。该题的正确答案是将angrily改为angry。

  【课本重点】Well, I hope you're enjoying my school in New York.

  【中考考点】Do you enjoy______football? I hear there will be a football match tomorrow.

  A. playing B. play C. played D. to play

  【解析】enjoy意为“喜欢,欣赏”,后可接名词或代词作宾语。如果其后是接动词,则只能接动词的V-ing形式。故该题只能选A。

  【课本重点】I think I'm getting a cold too.

  【中考考点】-What's the matter with you?

  -I caught______bad cold and have to stay in______bed.

  A. a; (不填) B. a; the C. a; a D. the ; the

  【解析】get(a) cold, take(a) cold和catch (a) cold都是表示“感冒”,其中的不定冠词a在没有形容词修饰cold时常可省略,但cold之前有形容词修饰时则不能省略。而have a cold也可以表示感冒,但其中的a在任何情况下都不能省略。又因为躺在床上习惯说stay in bed,故该题的正确答案是A。

1. What's the matter?

语境: 当看到一个人气色不好、或面带憔悴等时,我们可以用此句询问对方,表示“你怎么不舒服?”、“出了什么事?”、“为什么不高兴?”等。下面请本期的两位嘉宾主持给大家演示一下:

1)卡丁奇奇: What's the matter with you, Tom?

馋嘴胖胖: I have a headache.

2)卡丁奇奇: What's the matter? You look so pale.

馋嘴胖胖: I'm not feeling well. I have a cold, I think.

相关连接:问某人有何不舒服时,英语中还可用What's wrong with...?/What's up with...?/What's the trouble with...?等句型,前面或后面通常还要加上You look pale./You don't look well.等类的句子。

2. You should...

语境: 当婉转地提出一个建议时常用此句型。

实例:

1)卡丁奇奇: I have a toothache.

馋嘴胖胖: Maybe you should see a dentist.

2)卡丁奇奇: I have a fever.

馋嘴胖胖: You should drink lots of water.

相关连接:

类似此说法还有You'd better.../Perhaps you should.../You need...等。注意它们的否定形式是You'd better not.../You shouldn't.../You needn't...。
