(一)句型(一)
　such+名词性词组+that…
So+形容词/副词+that…——如此……以致……
例如：(1)She is such a good teacher that we all love ，咱们都爱她。
　(2)It was such a hot day that they didn’t go out for a walk as ，她们没有像往常同样去散步。
注意点：
+a+形容词+名词+that…，可以改写成：so+形容词+a+名词+that…，例句(1)可以改写成：She is so good a teacher that we all love her.
+形容词+名词复数或不可数名词+that…构造中，形容词如果是many/few或much/little时，用so不用such，即：so+many/few+可数名词复数+that…，so+much/little+不可数名词+that…
(1)There are so many people in the room that I can’t get ，我进不去。
(2)The man has so much money that he can buy a ，她能买一辆小汽车。
句型(二) （就近一致）
There be…，either…or…，neither…nor…，not only…but also…

(3)Either you or I am leaving for ，要么我去上海。
(4)Neither you nor he is 。
　(5)Both Jack and Tim are English.
Jack和Tim是英国人。
注意点：
当这几种句型连接主语时，谓语动词人称和数要考虑“就近原则”，对比both…and… 来记忆，both
…and…连接主语时视为复数。

形容词/副词+enough+to do …——足够……做某事
　例如：(1)There is enough room to hold these people to have a 。

注意点：
enough做副词修饰形容词或副词时，放在所修饰词背面，句子可以用so…that…句型改写。例句(2)可以改写为：The boy is so strong that he can carry the heavy ，能搬动这只箱子。
句型(四) too .... to .....
too+形容词/副词+to do…——太……以致不能……
例如：(1)I was too excited to say a 。
