　參考答案&解析：

　　1、A　passed 發(fā)生had begun 之后，故用過去時passed。例如;Since he had died, the town changed a lot.

　　2、D　would do sth. 有時表示“過去往往做某事”，如：Whenever his boss came in, he would stand up.

　　3、D　“三年來一直寫”，而且“現(xiàn)在仍在寫”，故用現(xiàn)在完成進行時has been writing 。“到現(xiàn)在已經(jīng)寫了”文章，故用現(xiàn)在完成時has written 。再如：He has been working as manager for fourteen years and he has signed a hundred contracts.

　　4、C　句子說“現(xiàn)在找不到”(can't find), 故put 用現(xiàn)在完成時(have put), 表示與現(xiàn)在有關(guān)。

　　5、D　“知識來自實踐”是真理，故用現(xiàn)在時。例如：Practice makes perfect. /Time and tide wait for no man.
