1、Six years ______ since I had begun studying English. A. passed by B. has passed by C. had passed by D. passing by
A. were to sit B. sat C. were sitting D. would sit
A. has written/has written B. has been writing/wrote C. is writing/wrote D. has been writing/has written
A. you put B. you have put C. have you put D. did you put
A. had come B. came C. would come D. comes
1、A passed 发生had begun 之后,故用过去时passed。例如;Since he had died, the town changed a lot. 2、D would do sth. 有时表示“过去往往做某事”,如:Whenever his boss came in, he would stand up. 3、D “三年来一直写”,而且“现在仍在写”,故用现在完成进行时has been writing 。“到现在已经写了”文章,故用现在完成时has written 。再如:He has been working as manager for fourteen years and he has signed a hundred contracts. 4、C 句子说“现在找不到”(can't find), 故put 用现在完成时(have put), 表示与现在有关。 5、D “知识来自实践”是真理,故用现在时。例如:Practice makes perfect. /Time and tide wait for no man. |
