2.反意疑问句

①否定陈述句＋肯定提问如：She doesn’t come from China, does she?

You haven’t finished homework, have you?

①提问部分用代词而不用名词如：Lily is a student, isn’t she?

①陈述句中含有否定意义的词，如little, few, never, nothing, hardly等。其反

意疑问句用肯定式。

如：He knows little English, does he?他一点也不懂英语，不是吗？

2）as + 形容词或副词原级+ as 表示双方在某个方面一样。如：

5.辨析beat/win

相同点：都是动词，表示“赢”

不同：beat+人/win+比赛，竞赛，战争等名词。如：

We played very well, and beat them. 我们发挥得很好，击败了他们。

They won the match this time. 这次他们赢了这场比赛。

6.care about意为“关心；在意”，期中care是动词如：

We should care about the old people.我们应该关心老年人。

care for表示“喜欢”，“关心”之意，后接名词或v-ing形式作宾语，take care of

也有这个意思。

He cared nothing for skating. 他对滑冰没有兴趣。

In our class, we care for each other. 在我们班上，我们相互关心。 Maria takes good care of everybody. 玛丽亚很关心大家。

【友情链接】care for 还可以表示“照顾”，“照料”，相当于take care of 或look after 。

=You must look after yourselves. 你们要照顾好自己。 The children are well cared for in the nurseries.

两朵花都很漂亮。

both…and…两者都……（复数谓语） 反义词组：neither…nor…两者都不……（谓语单复数按照就近原则） 【友情链接】 both 与 all

both 指代两者； all 指代三者或三者以上 如： My parents are both fine 。 我父母都好。 We are all here 。 我们都在这儿。

10. be like 意为“像”，这里的like 是介词。如：

She is like her mother 。 她长得像他妈妈。 like 做动词，意为“喜欢”，构成短语 like sth./ sb. 喜欢某物/某人

like to do sth. 喜欢做某事 如：I like to have friends who are like me.

我喜欢交像我一样的朋友。

like diong sth. 11. need 是动词，需要。

need sth.需要…… Plant needs water 。

need to do sth. 需要做…… You didn’t need to tell him the news ，

it just made him sad

need doing sth.=need to be done 需要被怎么样 Flowers need watering 。 【拓展】need 作情态动词时，后面+动词原形，意思是必要，必须。这时need 多用于疑问句，否定句或条件状语从句中。如： You needn’t talk so loud. 你不必这么大声说话。 11. As long as 只要；既然。如：You don’t need a lot of friends as long as they’re good.

你不需要很多朋友，只要他们好就可以了。

12.It’s not necessary to be the same.完全一样是没有必要的。

我的系行车和你的不一样。

14. serious 意为“严肃的；认真的；严重的” 如：

他对那件事很认真。

对你来说没那么严重。

16. be talented in music 有音乐天赋
