2、yet?PresentationGrammar現(xiàn)在完成時用在什么地方呢？當(dāng)我們要表達(dá)“某人曾經(jīng)做過某事”, “某人已經(jīng)做了某事”等意思時, 英語要用“現(xiàn)在完成時”來表達(dá)。 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現(xiàn)在完成時的結(jié)構(gòu)：has/have + done (動詞過去分詞)She / He / It / 或sb.的單數(shù)形式has done sth.I/We/You/

3、They或sb.的復(fù)數(shù)形式have done sth.現(xiàn)在完成時的一般疑問句形式是：Has done sth.?she / he / it / 或sb.的單數(shù)形式Have done sth.? I / we / you / they / 或sb.的復(fù)數(shù)形式現(xiàn)在完成時的肯定形式是：我父母曾經(jīng)坐船去大連旅游。她已經(jīng)完成作業(yè)。我父母未曾坐船去過大連旅游。My parents have travelled to Dalian by ship.She has finished her homework.My parents havent travelled to Dalian by ship.她還沒有完

4、成作業(yè)。你父母曾經(jīng)坐船去大連旅游過嗎？她已經(jīng)完成作業(yè)了嗎？Have your parents travelled to Dalian by ship?Has she finished her homework?She hasnt finished her homework.要表達(dá)“剛剛做完某事” “已經(jīng)做完某事”時，我們同樣可以用現(xiàn)在完成時。例如:I have just heard the news.Astronauts have already been to the moon.可以看出，just 用來表示“剛剛”，already 用來表示“已經(jīng)”，一般置于have/has之后，兩者都用于肯

5、定句，在否定句中則要用yet,表示“還（未）”。例如：The scientists havent heard from it yet. have been to 與 have gone to 的區(qū)別 1. （1）have/has been to意為“曾經(jīng)去過某地”，表示現(xiàn)在已經(jīng)不在那里了?？膳cjust, ever, never等連用。例如：Ive just been to the post office. 我剛才去郵局了。Have you ever been to Hangzhou? 你曾經(jīng)去過杭州嗎？Mary has never been to the Great Wall. 瑪麗從未去過長

6、城。（2）have/has been to 后面可接次數(shù)，表示去過某地幾次。Ive been to Beijing three times. 我去過北京三次。They have been to that village several times. 他們已經(jīng)去過那個村莊好幾次了。 2. have /has gone to 意為“到某地去了”，表示到了某地或正在去某地的途中?？傊?，說話時該人不在現(xiàn)場，一般不用第一、第二人稱代詞作句子的主語。例如： Where is Tom? 湯姆在哪里？ He has gone to the bookshop.他到書店去了。與現(xiàn)在完成時連用的幾個副詞：肯定句:疑

7、問句和否定句: yet 常置于句末already, never, ever, just一般置于助動詞have/has之后，過去分詞之前。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
