Step 5

问题探究

1．我买这本书三周了。

I_have_had_this_book_for_three_weeks. 现在完成时态还表示过去发生的动作或存在的状态，一直持续到现在，也许还将继续下去，可以和表示从过去某一时刻延续到现在的一段时间的状语连用，即：for ＋时间段；since＋时间点/从句；in(during) the last(past) ten years等，谓语只可用延续性动词．

2．我借这本书两个星期了。

①I have kept the book for two weeks. ②I have kept the book since two weeks ago. 现在完成时中

for 与

since的区别：

for ＋

段时间，常与延续性动词的现在完成时连用

since有四种用法：

①since＋时间点

eg：since last night ②since＋时间段＋ago

eg：since two years ago ③since ＋从句(用一般过去时态)

eg：since they came to China ④

It's (has been) ＋一段时间＋since 从句
