重要提醒：
think,believe,suppose等接賓語從句，表示否定時要否定主句。變為反意疑問句時，若主語是第一人稱，簡短問句與賓語從句的主謂語保持一致，若主句主語是其他人稱，與主句主謂語保持一致。例句①變為反意疑問句應為：I can't believe she is right,is she?
9. such+名詞性詞組+that...;so+形容詞/副詞+that... 如此……以致……
如：
①She is such a good teacher that we all love her.她是一個好老師,我們都愛她。
②It was such a hot day that they didn't go out for a walk as usual.這么熱的天氣,他們沒有像往常一樣去散步。
重要提醒：
(1)“such+a(an)+形容詞+名詞+that...”，可以改寫成“so+形容詞+a(an)+名詞+that...”，例句①可以改寫成：She is so good a teacher that we all love her.
(2)在“such+形容詞+名詞復數或不可數名詞+that...”結構中，形容詞如果是many/few或much/little時，用so不用such，即：so+many/few+可數名詞復數+that... ，so+much/little+不可數名詞+that...。如：
①There are so many people in the room that I can't get in.
房間里人太多,我進不去。
②The man has so much money that he can buy a car.

③Either you or I am leaving for Shanghai. 要么你去上海，要么我去上海。
④Neither you nor he is right. 你和他都不對。
⑤Both Jack and Tim are English. Jack和Tim都是英國人。
重要提示：
當這幾個句型連接主語時，謂語動詞的人稱和數要遵循“就近原則”。對比both... and...來記憶，both... and...連接主語時視為復數。
11. enough+名詞+to do... 有足夠的……做某事;
形容詞/副詞+enough+to do... 足夠……做某事。如：
①There is enough room to hold these people to have a meeting. 有足夠的地方容下這些人開會。
②The boy is strong enough to carry the heavy box. 這個男孩兒力氣夠大,能搬動這只箱子。
重要提示：
enough作副詞修飾形容詞或副詞時，放在所修飾詞的后面，句子可以用so... that...句型改寫。例句②可以改寫為：The boy is so strong that he can carry the heavy box.
12. enjoy doing sth.喜歡(愛好)做某事;
