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) ⑵How long is it since we left Beijing?(自从我们离开北京已有多久了 4.祈使句+and (那么)... eg.Go straight on and you’ll see a school. =If you go straight on, you’ll see a school. 5.祈使句+or...否则... eg.Work hard, or you will fall behind the other students. =If you don’t work hard, you’ll fall behind the other. 6. The+比较级...，the+比较级... 越...越... eg.⑴The more, the better. 越多越好。 ⑵The harder you work on it, the better you’ll be at it.(你越用功，你就越好。) (责任编辑：admin) |
