七年级上现在完成时专题
现在完成时
定义:
表示过去发生的动作到①持续到现在或者现在结束②对现在造成的影响或结果。
结构:
主语+have/has+动词过去分词+其他。
时间状语:
already(已经),yet(已经),just(刚刚、仅仅),ever(曾经),never(从不),before(以前),since+时间点(自从…),for+一段时间,inthepastfewyears(在过去的几年中),sofar(到目前为止)等等。
【知识梳理1】
肯定句变否定句:
现在完成时构成否定句时,只需在助动词have/has后面加not就行。
havenot,hasnot的缩略式分别为haven't,hasn't。
另外,肯定句中有ever,already时,改为否定时要分别改成never,yet,yet放句尾。
【例题精讲】
例1.Ihavealreadyfinishedmyhomework.→Ihaven'tfinishedmyhomeworkyet.我还没有完成我的作业。
例2.Wehaveeverspokentoaforeigner.→Wehaveneverspokentoaforeigner.我们从来没有和外国人说过话。
【巩固练习】
1.Shehasalreadydoneherhomework.→
2.Ihaveeveraskedhimtowritetohisfriend.→
3.翻译:
他从来都没有告诉过我关于他的家人。
4.Hehasalreadycompletedthecomposition.(否定句)
He________completedthecomposition________.
5.翻译:
我的爷爷从来都没有去过北京。
【知识梳理2】
陈述句变一般疑问句:
把陈述句中的have或has放到句首,句末打问号,同时把句中的some,already改为any,yet就构成了一般疑问句。
肯定回答用“Yes,主语+have/has.否定回答用“No,主语+haven't/hasn't.”有时也可以用“No,notyet./No,never./No,notevenonce.”等,当陈述句中有never时,变一般疑问句时要把never变成ever。
