☆重點句型☆
1. 英語句型中的否定轉移
在英語中，如果主句的動詞是think, suppose, expect, believe, imagine 之類的動詞，其否定形式應轉移到主句。構成反意疑問句時，主語是第一人稱，以從句為準；主語是其它人稱，以主句為準。 i don't think you're right, are you? 我認為你不對，不是嗎？
mary doesn’t expect she can have a long holiday, does she?
練習：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._________________________________________我認為你的答案是不對的，不是嗎？
反義疑問句的回答是根據實際情況來回答的。肯定回答：yes, i do.否定回答：no, i don't. 注意: 要前后保持一致，切不可說成“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. 皮埃爾與我確實在舞會上玩得很開心。
助動詞do / does / did + 動詞原形表示 “確實，的確，一定”。常常用在肯定句或祈使句中，起加強語氣的作用。有人稱和時態的變化。例如：
_______send me e-mail immediately you arrive at beijing. 你一到北京，一定要給我發電子郵件
he __________ smoke two packs of cigarettes every day. 他確實每天抽兩包煙。
you ________look nice today. 你今天看起來真漂亮。
we ________need help those days. 在那些日子里我們的確需要幫助。
____ careful while crossing the street.
a. your being b. to be c. do be d. being
3. be (was / were) to do 此結構表示安排、命令、職責、義務、用途、可能性、命中注定等。
you are to be back by 11 o'clock. 你得在11點鐘前回來。(命令)
