求__she took a walk in the park,she found very strange thing.

題目：

求__she took a walk in the park,she found very strange thing. A.since B.until C.as D.while
爲什麼選C不選D as和while表示當.時候 有什麼區別?

解答：

1.A.(it在這裡做形式賓語.考試只會考這種情況(初中).)
2.A.這裡的one指代了前面的a big cake.
如果選B的話那後面那句應該是:Can you give it to me.
C不選因爲表數量時another是與one搭配的,即:one...another...
D.any是一些(前面說的是a big cake,一個).並且只用於否定句中.
3.A.Yes,he did.有一個口則:肯定句(即Andy stole Mary's sheep)
肯定回答,否定反對.(他偷了,Yes he did;他沒偷,No he didn't.)
若題目是:Andy didn't steal Mary's sheep,did he?回答則是:No he didn't.
分析如下:否定句(Andy didn't steal Mary's sheep)
否定回答,肯定反對.(他偷了,No,he didn't;他沒偷:Yes,he did)
這個口則很有用.做題的時候很方便:
總結,即:肯定句,肯定回答,否定反對
否定句,否定回答,肯定反對.
