現(xiàn)在完成時態(tài)與一般過去時態(tài)的區(qū)別

1、現(xiàn)在完成時態(tài)與一般過去時態(tài)的區(qū)別1）一般過去時態(tài)表示過去某時發(fā)生的動作或單純敘述過去的事情，強調(diào)動作；現(xiàn)在完成時態(tài)中動作為過去發(fā)生的，強調(diào)過去的事情對現(xiàn)在的影響，強調(diào)的是影響。如:i saw this film yesterday. （強調(diào)看的動作發(fā)生過了） i have already seen this film.（強調(diào)對現(xiàn)在的影響，電影的內(nèi)容已經(jīng)知道了） i havent finished my work yet. (強調(diào)對現(xiàn)在的影響，還有工作要做，不能去玩) when did you finish your homework? (詢問過去的動作所發(fā)生的時間，與現(xiàn)在無關(guān))2）一般過去時態(tài)

2、表示動作在過去已經(jīng)停止；現(xiàn)在完成時態(tài)可以表示過去開始的動作一直延續(xù)到現(xiàn)在。如：ann visited her uncle last weekend.(visit這個動作在過去已經(jīng)停止) they have lived here since 1983.(live here 這個動作從1983年開始，一直延續(xù)到現(xiàn)在)3）一般過去時態(tài)常用非延續(xù)性動詞，如borrow, buy, come, go, leave, start, die, finish, become等?，F(xiàn)在完成時態(tài)可表示持續(xù)到現(xiàn)在的動作或狀態(tài)，與時間段連用時，動詞一般是延續(xù)性的，如keep, have, live, teach, le

3、arn, work, study, know, be等。如：he joined the league three years ago .(join是短暫動詞）he has been in the league for three years.（be in表狀態(tài)，在團內(nèi)的狀態(tài)可延續(xù)）he has been a league member for three years. （是團員的狀態(tài)可延續(xù)）4）一般過去時態(tài)常與具體的時間狀語連用，而現(xiàn)在完成時態(tài)通常與模糊的時間狀語連用，或無時間狀語。一般過去時態(tài)的時間狀語：yesterday, last night/week/month/year，ago, i

4、n1980, just now等，皆為具體的時間狀語.現(xiàn)在完成時態(tài)的時間狀語：for+時間段, since+過去的時間點/一般過去時態(tài)的句子, so far, , up to now, in the past .years, 等，皆為不確定的時間狀語。如：tim wrote a letter to his brother last night.（last night 為具體的過去時間狀語，所以用一般過去時態(tài)）ive learned english for three years. （for three years為時間狀語，是個時間段）一、用since和for填空。1._ two years2
