初中第一英语知识点总结【1】
1.There be结构
a.这是英语中常见的一种结构，表示“某地有某物”其含义为“存在有”。
eg.There are twenty girls in our class.have也解释为“有”但是与there be有区别，它的含义是“所有，属有”，其主语为某人。eg.I have a nice watch.
b.There be结构中的be动词要和后面所跟名词保持一致。
c.There is a river near our school.
否：There is not a river near our school.
问：Is there a river near our school.
回答：Yes,there is.No,there isn’t.
划⑴How many rivers are there near our school?
⑵What’s near our school?
d.there be结构的一般将来时，同学们较难掌握，其正确形式为：there is going to be
e.反意疑问句的构成：There is no water in the glass,is there?
2.so,neither引导的倒装句,为了避免和前一句话的内容重复，英语中习惯用so,neither引导的倒装句。
a.So+be(助动词，情态动词)+主语。表示某人也是如此。
eg.Mike has bought some foreign stamps.
So has Bob.=Bob has bought some,too.
b.Neither+be(助动词，情态动词)+主语，表示某人也不。
eg.Mother has never been to Japan.
Neither has Father.=Father has never been to Japan,either.
c.So+主语+be(助动词，情态动词)。表示果真如此(赞同),请同学们与a.区别。
eg.A:Mike is right in the classroom.
B:So he is.=He is really in the class room.
3.It’s+时间+since动词过去式。自从...起已有...时间了。
⑴It’s two weeks since we met last.(自从我们上次见面已有两个星期了)

请注意:中文意思否定在从句中,但是英语的表达否定在主句中。
15.prefer A to B=like A better than B更喜欢A不怎么喜欢B.
eg.I prefer fish to chicken.=I like fish better than chicken
16.had better do sth.最好干某事.
否定:had better not do sth.
特别注意:had better后面跟be动词词组,不可漏掉be.

=sb.spend some time on sth.(in)doing sth.
eg.It took me half an hour to do the work.=I spent half an hour in doing the work.

pay的过去式为paid而不是payed.
eg.I paid thirty yuan for the coat.
