“某人已经做了某事”等意思时,英语要用“现在完成时”来表达。6否定句Ihavenotworked.He/Shehasnotworked.Theyhavenotworked.

肯定句Ihaveworked.He/Shehasworked.Theyhaveworked.haven’thasn’thaven’t现在完成时的结构：has/have+done(动词过去分词)7She/He/It/或sb.的单数形式hasdonesth.I/We/You/They或sb.的复数形式havedonesth.现在完成时的一般疑问句形式是：Hasdonesth.?she/he/it/或sb.的单数形式Havedonesth.?I/we/you/they/或sb.的复数形式现在完成时的肯定形式是：8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。MyparentshavetravelledtoDalianbyship.Shehasfinishedherhomework.Myparentshaven’ttravelledtoDalianbyship.9她还没有完成作业。你父母曾经坐船去大连旅游过吗？她已经完成作业了吗？HaveyourparentstravelledtoDalianbyship?Hasshefinishedherhomework?Shehasn’tfinishedherhomework.10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:Ihavejustheardthenews.Astronautshavealreadybeentothemoon.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，两者都用于肯定句，在否定句中则要用yet,表示“还（未）”。例如：Thescientistshaven’theardfromit

yet.11

havebeento

与havegoneto

的区别

1.（1）have/hasbeento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：I’ve

just

beento

thepostoffice.我刚才去邮局了。Have

youever

beento

Hangzhou?你曾经去过杭州吗？Mary

has

never

beento

theGreatWall.玛丽从未去过长城。12（2）have/hasbeento后面可接次数，表示去过某地几次。I’ve

beento

Beijingthreetimes.我去过北京三次。They

havebeento

thatvillageseveraltimes.他们已经去过那个村庄好几次了。132.have/hasgoneto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：

—WhereisTom?——汤姆在哪里？

—He

hasgoneto

thebookshop.——他到书店去了。14与现在完成时连用的几个副词：肯定句:疑问句和否定句: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
