2、mmar现在完成时用在什么地方呢？当我们要表达“某人曾经做过某事”,“某人已经做了某事”等意思时,英语要用“现在完成时”来表达。第4页/共26页5 否定句I have not worked.He/She has not worked.They have not worked.肯定句I have worked.He/She has worked.They have worked.haventhasnthavent现在完成时的结构：has/have+done(动词过去分词)第5页/共26页6She/He/It/或sb.的单数形式has done sth.I/We/You/They或sb.的复数形式

3、have done sth.现在完成时的一般疑问句形式是：Has done sth.?she/he/it/或sb.的单数形式Have done sth.?I/we/you/they/或sb.的复数形式现在完成时的肯定形式是：第6页/共26页7我父母曾经坐船去大连旅游。她已经完成作业。我父母未曾坐船去过大连旅游。My parents have travelled to Dalian by ship.She has finished her homework.My parents havent travelled to Dalian by ship.第7页/共26页8她还没有完成作业。你父母曾经坐

5、，在否定句中则要用yet,表示“还（未）”。例如：The scientists havent heard from it yet.第9页/共26页10 have been to 与 have gone to 的区别 1.（1）have/has been to意为“曾经去过某地”，表示现在已经不在那里了。可与just,ever,never等连用。例如：Ive just been to the post office.我刚才去邮局了。Have you ever been to Hangzhou?你曾经去过杭州吗？Mary has never been to the Great Wall.玛丽从未去

6、过长城。第10页/共26页11（2）have/has been to 后面可接次数，表示去过某地几次。Ive been to Beijing three times.我去过北京三次。They have been to that village several times.他们已经去过那个村庄好几次了。第11页/共26页122.have/has gone to 意为“到某地去了”，表示到了某地或正在去某地的途中。总之，说话时该人不在现场，一般不用第一、第二人称代词作句子的主语。例如：Where is Tom?汤姆在哪里？He has gone to the bookshop.他到书店去了。第12
