現(xiàn)在完成時(shí)及其考點(diǎn)
考點(diǎn)一：考查基本概念
例 Both his parents look sad . Maybe they _________what's happened to him .（呼和浩特）
Ａ. knew Ｂ. have known Ｃ. must know Ｄ.will know
簡(jiǎn)析：現(xiàn)在完成時(shí)主要強(qiáng)調(diào)過(guò)去發(fā)生的動(dòng)作對(duì)現(xiàn)在造成的影響，或過(guò)去發(fā)生的動(dòng)作還未結(jié)束，一直持續(xù)到現(xiàn)在或?qū)?lái)，重點(diǎn)在于對(duì)現(xiàn)在的影響。這種考查難度較大，往往無(wú)時(shí)間狀語(yǔ)，需要從上下文分析、推理才行。故上兩側(cè)根據(jù)上下文分析、推理，正確答案是Ｂ。
考點(diǎn)二：考查時(shí)間狀語(yǔ)
例1. He has _______ been to Shanghai , has he ?
Ａ. already Ｂ.never Ｃ.ever Ｄ. still
例2. Have you met Mr Li ______？
Ａ. just Ｂ. ago Ｃ.before Ｄ. a moment ago

Ａ. is writing Ｂ.was writing Ｃ.wrote Ｄ.has written
例4.-Our country ______ a lot so far . -Yes . I hope it will be even ______ .
Ａ. has changed ; well Ｂ. changed ; good

Ａ. was ; studying Ｂ. will ; study Ｃ. has ; studied Ｄ. are ; studying

Ａ. know Ｂ. had known Ｃ. have known Ｄ. knew
例7. Harry Potter is a very nice film .I_______ it twice .
Ａ. will see Ｂ. have seen Ｃ. saw Ｄ.see
簡(jiǎn)析：現(xiàn)在完成時(shí)的時(shí)間狀語(yǔ)常有如下四類：
⑴現(xiàn)在完成時(shí)常與already（已經(jīng)），just（剛剛，正好），ever（曾經(jīng)），never（從來(lái)，也不；從不），before（以前），yet（仍然）等連用。故例1應(yīng)選B；例2應(yīng)選C。
⑵現(xiàn)在完成時(shí)常與recently（近來(lái)），so far（到目前為止），in the past/“l(fā)ast + 一段時(shí)間”等時(shí)間狀語(yǔ)連用。因?yàn)樯鲜龆陶Z(yǔ)表示的是從現(xiàn)在起往前推算的一段時(shí)間，句中的動(dòng)作是從過(guò)去某一時(shí)間或時(shí)刻開始持續(xù)到現(xiàn)在的。故例3應(yīng)選D，例4應(yīng)選C。
⑶現(xiàn)在完成時(shí)時(shí)常與“for +時(shí)間段或since +過(guò)去時(shí)間點(diǎn)”連用（含從句，從句過(guò)去時(shí)）。故例5應(yīng)選C，例6應(yīng)選C。
⑷現(xiàn)在完成時(shí)還與once（一次），twice（兩次），three times（三次），several times（幾次）等表示重復(fù)次數(shù)的詞語(yǔ)連用。故例7應(yīng)選B。
考點(diǎn)三：考查與一般過(guò)去時(shí)的區(qū)別
例1. -These farmers have been to the United States .
-Really ? When _____ there ?
Ａ. will they go Ｂ. did they go
Ｃ. do they go Ｄ. have they gone
例2.-______ you ___ your homework yet ? -Yes . I _____ it a moment ago .
Ａ. Did ; do ; finished Ｂ. Have ; done ; finished
Ｃ. Have ; done ; have finished Ｄ. will ; do ; finish
簡(jiǎn)析：現(xiàn)在完成時(shí)與一般過(guò)去時(shí)容易混淆，就是因?yàn)樗鼈兯硎镜膭?dòng)作都發(fā)生在過(guò)去，但二者又有區(qū)別：一般過(guò)去時(shí)表示過(guò)去某個(gè)時(shí)間發(fā)生的事、存在的狀態(tài)或經(jīng)常發(fā)生的動(dòng)作，說(shuō)話的側(cè)重點(diǎn)在于陳述一件過(guò)去的事情，與現(xiàn)在沒(méi)有關(guān)系；現(xiàn)在完成時(shí)表示與現(xiàn)在有關(guān)系的發(fā)生在過(guò)去的動(dòng)作，它不與表示過(guò)去的時(shí)間狀語(yǔ)（如yesterday , last week , a moment ago等）連用。故例１、２的正確答案皆為B。
考點(diǎn)四：考查非延續(xù)性動(dòng)詞的用法
例1. His father ______ the Party since 1978 .
Ａ. joined Ｂ. has joined Ｃ. was in Ｄ. has been in
例2.-Do you know him well ?
- Sure .We _________ friends since ten years ago .
Ａ. were Ｂ. have been Ｃ. have become Ｄ. have made
例3.-How long have you ____ here ?-About two months .
Ａ. been Ｂ. gone Ｃ. come Ｄ. arrived
例4. Hurry up! The play __________ for ten minutes .
Ａ. has begun Ｂ. had begun
Ｃ. has been on Ｄ. began
例5. His uncle died two years ago .（改變句子，句意不變）
His uncle has _______ for two years
例6. Her mother has been a Party member for three years .（同義句）
Her mother _______ the Party three years ________ .
例7. It _____ ten years since he left the army .
Ａ. is Ｂ. has Ｃ. will Ｄ. was
簡(jiǎn)析：現(xiàn)在完成時(shí)中，非延續(xù)性動(dòng)詞不能與for和since引導(dǎo)的表示一段時(shí)間的狀語(yǔ)連用，通常是用相應(yīng)的延續(xù)性動(dòng)詞來(lái)代替。常用的非延續(xù)性動(dòng)詞及替代形式如下：
close-→be closed, put on→wear , open-→be open
get up-→be up, finish/end-→be over , lose-→be lost ,
marry-→be married(to), fall asleep/ go to sleep -→be asleep ( sleep ) ,
get to know-→ know come/arrive-→be here/in ,
come/get back-→be back , go/leave-be away , become -→be ,
borrow -→keep , buy-→have , begin/start-→be on ,
die-→be dead , join-→be in/be a ember of．．． ,
catch a cold-→ have a cold等，
故例1、2、3、4的正確答案依次為：D、B、A、C。例5應(yīng)填been dead 。其次，可以用相應(yīng)的延續(xù)性動(dòng)詞的過(guò)去時(shí)表示，故例6應(yīng)填joined；ago。再次，還可用“It is + 一段時(shí)間＋since從句”來(lái)表示，故例７應(yīng)選A。
考點(diǎn)五：考查詞組have/has been in / to與have/has gone to的區(qū)別
例1. Miss Green isn't in the office . she_______ to the library .
Ａ.has gone Ｂ. went Ｃ.will go Ｄ. has been
例2. My parents ______ Shandong for ten years .
Ａ. have been in Ｂ. have been to
Ｃ. have gone to Ｄ.have been
簡(jiǎn)析：“have/has gone to + 地點(diǎn)”表示“某人去了某地（還未回來(lái)）”，指主語(yǔ)所指的人不在這兒。“have/has been in + 地點(diǎn)”表示“在某地呆了多長(zhǎng)時(shí)間”，常與表示時(shí)間的狀語(yǔ)連用。“have/has been to +地點(diǎn)”表示“曾經(jīng)去過(guò)某地（但現(xiàn)在已不在那兒）。”故例1、2的正確答案皆為A。
