3.小组展示，仿造编写对话
【质疑互究】
一.And check out these soft toys and board games for younger kids.
1.check out意为_____________
2. 翻译：察看一下所有的儿童书籍______ _______all the books for children.
二.现在完成时中for+时间段的用法:
I have had the book for three months.这本书我已经买了三个月了。
现在完成时表示过去已经开始,持续到现在的动作或状态,可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,如for+时间段、since+过去的时间点、疑问词how long。
注意:此种用法中表示持续动作或状态的动词必须是延续性动词(否定句除外)
短暂性动词 ―――延续性动词
buy---have, borrow---keep, leave---be away, come---be in.
1.他加入“绿色中国”已经三年了。
He the Greener China for three years.
2.He died 10 years ago.(改为同义句)
He for 10 years.
三．since的用法:
1.since,后接某一确定的时间点,也可接句子,句子一般用过去时,主句谓语动词是持续性动词,常与现在完成时态、现在完成进行时态连用。
2.“It is(has been)+时间+since+短暂性(持续性)动词的过去时”,表示“自从(不)……以来到现在已有(多久)”。
用since或for填空。
