求救几道英语选择题

1.B 过去住在上海
2.C 现在完成时

1.B used to do过去常做某事
be/get used to doing习惯于做某事
2.C根据题意，应该是指做过的事，所以用过去完成时

1.I ( ) to live in Shanghai when I was a boy.
A was used B used
C got used D used not
Key:B
use to do sth:曾经做某事
be used to doing sth:过去习惯做某事
be used to do sth:被用来做某事
在考试中这三个意思经常一起考的.注意区分哦^-^
2.( ) your best? It's not satisfactory ,I'm afraid you will have to do it again.
A Do you try B Were you trying
C Have you tried D Have you been trying
Key:C
这里应该选现在完成时,表示动作从过去开始一直延续到说话的时候,可能停止也可能继续.
