☆重点句型☆

1. 英语句型中的否定转移

在英语中，如果主句的动词是think, suppose, expect, believe, imagine 之类的动词，其否定形式应转移到主句。构成反意疑问句时，主语是第一人称，以从句为准；主语是其它人称，以主句为准。 i don"t think you"re right, are you? 我认为你不对，不是吗？

mary doesn’t expect she can have a long holiday, does she?

练习：a. i don"t suppose i shall be back until 9 o"clock, ________________?

b. they all think that english is very important, _______________?

c. i don’t believe he can afford to buy an apartment, _____________?

d. he didn’t think that the news was true, ________________?

e._________________________________________我认为你的答案是不对的，不是吗？

反义疑问句的回答是根据实际情况来回答的。肯定回答：yes, i do.否定回答：no, i don"t. 注意: 要前后保持一致，切不可说成“yes, i don"t.”或“no, i do.

(1) ---his sister didn’t attend the meeting, did she?

---______. she fell ill that day.

a. yes, she did. b. no, she did. c. yes, she didn’t d. no, she didn’t

(2) ----he likes playing football, doesn’t he?

---______. he does it every day.

a.yes, he doesn’t. b. no, he doesn’t. c. yes, he does. d. no, he does.

2. pierre and i did have a very good time at the ball. 皮埃尔与我确实在舞会上玩得很开心。

助动词do / does / did + 动词原形表示 “确实，的确，一定”。常常用在肯定句或祈使句中，起加强语气的作用。有人称和时态的变化。例如：

_______send me e-mail immediately you arrive at beijing. 你一到北京，一定要给我发电子邮件

he __________ smoke two packs of cigarettes every day. 他确实每天抽两包烟。

you ________look nice today. 你今天看起来真漂亮。

we ________need help those days. 在那些日子里我们的确需要帮助。

____ careful while crossing the street.

a. your being b. to be c. do be d. being

3. be (was / were) to do 此结构表示安排、命令、职责、义务、用途、可能性、命中注定等。

you are to be back by 11 o"clock. 你得在11点钟前回来。(命令)
