4.合作探究与展示

1）.合作释疑

since 后接时间点或从句（一般过去时），表示某动作或状态是从哪个时间开始持续到现在；也可以接“时间段+ago”, 可与“for+时间段”替换。

常见句型有：sb. have/has done sth. for +时间段/ since+时间段+ago / since + 时间点或者从句，意为“某人已经做某个动作或持续状态至今已经有多长时间了”。

也可用于句型It is / It has been+时间段+since+从句（一般过去时）中，意为“某个动作或状态持续至今已经有多长时间”。

【练一练】Amy已经回家乡十天了。

(1) Amy has been back to her hometown since _____________________.

(2) Amy has been back to her hometown for _____________________.

(3) It __________________________ since Amy came back to her hometown.

★持续性动词的现在完成时：若时间状语表示为时间段时，要用持续性动词。如：

I have come here for 3 years. (×) →I have been here for 3 years. (√)

与现在完成时有关的句型转换：

(4)She borrowed the book two weeks ago. →She _________________ the book since two weeks ago.

(5) Kate bought the radio 3years ago. →Kate _________________ the radio for 3

years.

(6) They left/went one year ago. →They _________________ for a year.

(7) They came to/arrive at this school in 1990. →They _________________ this school since 1990.
