5、ished) her homework?She hasnt done (finished) her homework.要表達“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。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，兩者都用于肯定句，在否定句中則要用yet,表示“還（未）”。如：The scientists havent heard from it yet. have been to

6、 與have gone to 的區(qū)別 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。可與just, ever, never等連用。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. 瑪麗從未去過長城。 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
