2、yet?PresentationGrammar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。 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)She / He / It / 或sb.的单数形式has done sth.I/We/You/

3、They或sb.的复数形式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：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.她还没有完

4、成作业。你父母曾经坐船去大连旅游过吗？她已经完成作业了吗？Have your parents travelled to Dalian by ship?Has she finished her homework?She hasnt finished her homework.要表达“刚刚做完某事” “已经做完某事”时，我们同样可以用现在完成时。例如:I have just heard the news.Astronauts have already been to the moon.可以看出，just 用来表示“刚刚”，already 用来表示“已经”，一般置于have/has之后，两者都用于肯

5、定句，在否定句中则要用yet,表示“还（未）”。例如：The scientists havent heard from it yet. 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. 玛丽从未去过长

6、城。（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。 2. 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。与现在完成时连用的几个副词：肯定句:疑

7、问句和否定句: yet 常置于句末already, never, ever, just一般置于助动词have/has之后，过去分词之前。already, just, ever, yet, never already, just ever, yet, neverA: Have you ?B: Yes, / No, (using already, just, ever, yet, never)Spaceship on Mars Astronauts have _ been to the moon but they have not been to any other planets.However
