1做题时,有没有什么简洁的方法能够马上判断出这句句子是定语从句还是同位语从句?
2 the reason 后面什么情况下跟that/why/for
3.我无法把握什么时候用being,having been done,
past form,到底什么样的句子一定要有明显的先后次序?
eg.___ their economic situations, they got some relief fund from the government.
　　a. Considering b. Considered
　　c. Having been considered d. Being considered
4.what do you think when....中的do you think能否换成
you think 为什么能或不能?

1做题时,有没有什么简洁的方法能够马上判断出这句句子是定语从句还是同位语从句?
===》看从句的引导词在从句中作不作成分：要作成分---定语从句；不作成分---同位语从句。
如： 1. The news that they had wun the game finally came.
（that不作成分---此句为同位语从句）
2. The new that I gave him is a little surprising.
（that作成分---此句为定语从句）
2 the reason 后面什么情况下跟that/why/for
1. I don‘t know the reason why he was late.
2. This is the reason I gave him last night.
3. I don’t know the reason for his being late.
看完上面3个小题后是否明白了？
后面跟that---reason在从句中作宾语/主语
后面跟why---reason在从句中作状语
后面for---reason后面是名词
3.我无法把握什么时候用being,having been done,
being done-----表示正在进行的被动动作/或这个被动动作和主句谓语同时进行。
being,having been done已经完成的被动动作

eg.___ their economic situations, they got some relief fund from the government.
　　a. Considering b. Considered
　　c. Having been considered d. Being considered
这里选 A。但与前面的解释无关。这里是现在分词的独立结构。
4.what do you think when....中的do you think不能换成you think...
如：What do you think we have a rest over there？如果按你所说就不是疑问句了
