【易錯點睛】

在現(xiàn)在完成時的考查中，以現(xiàn)在完成時與一般過去時的辨析較為常見。兩者有如下區(qū)別。

1.兩者都表示在過去發(fā)生的動作。但現(xiàn)在完成時側(cè)重過去的動作對現(xiàn)在造成的影響。而一般過去時側(cè)重于表過去的動作，與現(xiàn)在無關(guān)。如：

YesterdayI went to the zoo.昨天我去了動物園。(僅說明昨天去了動物園，與現(xiàn)在無關(guān))

LiLei has read the book.李磊已看過那本書。(說明李磊了解那本書的內(nèi)容)

2.連用的時間狀語不同：與現(xiàn)在完成時連用的時間狀語有already,yet, still, just, so far, in the last/past…, before, ever, never,since或for引出的時間等。而一般過去時則常與ago,yesterday, last…, in 2000, just now等連用。

Haveyou ever picked flowers or steeped on the grass in a park?你們曾在公園里摘過花或踩過草地嗎?

Fatherbought that watch ten years ago.爸爸十年前買了那塊手表。

Ihave never seen the film before.我以前從沒看過這部影片。

【易錯考點回顧】

1.—______ 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

【錯因分析】題干中有個yet，這是現(xiàn)在完成時常用的副詞，如果考生忽視了這一點，就容易錯選，而答語中有個amoment ago，這是一般過去時的常用時間狀語，所以在做時態(tài)題的時候，需把握住題干中的時間狀語，否則容易錯選。

【思路點撥】把握住現(xiàn)在完成時的使用特點，抓住題干中的關(guān)鍵詞和時間狀語即可快速的判斷出正確答案。

【正確答案】正確答案為B。句意：——你做完作業(yè)了嗎?——是的。我剛才做完的。根據(jù)問句中的yet可知應(yīng)該用現(xiàn)在完成時態(tài)，根據(jù)答語中時間狀語amoment ago可知應(yīng)該用一般過去時。故選B。

1.(2017北京中考)Lilyis my classmate. We _____ each other since she came to our school.

A.know B. knew C. have known D. will know

】

【答案C

解析：考查動詞的時態(tài)。since引導(dǎo)時間狀語從句時，從句用一般過去時，主句應(yīng)用現(xiàn)在完成時。故選C。

2.(2018青島)—It’stime to work now.

—OK,I’ll wake Carl up. He ______ for an hour.

A.has fallen asleep B. has been asleep C. fell asleep D.falls asleep

】

【答案B

解析：根據(jù)foran hour可知，這是一個表示一段時間的時間狀語，通常用于現(xiàn)在完成時中，并且動詞應(yīng)用延續(xù)性動詞，而fallasleep是瞬時性動詞，在完成時中應(yīng)變成持續(xù)性的狀態(tài)，故選B。

3.(2017常德)I______ Anna since three years ago.

A.knew B. know C. have known

答案：C

解析：根據(jù)句中的時間狀語sincethree years ago可知要用現(xiàn)在完成時，其結(jié)構(gòu)是have/has+過去分詞，故選C。
