初中英语重要短语和句型结构
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?
①There is going to _____ a football match this afternoon.
A.have B.watch C.be D.play
②They were sure that they were going to ____ a rest.
A.be B.have C.be on D.on
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)
⑵How long is it since we left Beijing?(自从我们离开北京已有多久了
