　　参考答案&解析：

　　1、C　“去年去”当然用过去时态(went)。又如：He has been writing for ten years and he wrote another story last week.

　　2、A　will 有时当情态动词用，意思是“愿意”，此时它不表示将来，如：If he will give us a hand, we will be grateful.

　　3、D　“现在正在练”(is practicing)，故用现在进行时。又如：He does physical exercise after six in the morning but he is doing it now at noon.

　　4、C　“过去坐下”，所以用过去时。seat 是及物动词，用在“主语 + 及物动词 + 宾语”句型里。此句中seat 是过去分词形式，作表语用，表示状态，它来自被动语态的过去分词。例如：I went in and was seated (= seated myself 或sat down) on a bench.

　　5、B　“知道”是感知动词，没有进行时。此句中的“知道”是现在的事实，故用现在时。又如：I think you know French.
