上一期介紹了英語語法：現(xiàn)在完成時(shí)的基本用法，這一期介紹英語語法：現(xiàn)在完成時(shí)的錯(cuò)誤用法。

現(xiàn)在完成時(shí)

動(dòng)名型have(has) +過去分詞

系表型have(has)been+表語

1.瞬間動(dòng)詞，不能與表示時(shí)間長度的狀語連用

他們已到達(dá)這里兩小時(shí)了。

×They has arrived here for 2 hours.

√They has been here for 2 hours since she got here.

這們小說家已經(jīng)死了10年了。

×The novelist has died for 10 years.

√The novelist has been dead for 10 years.

他的任務(wù)已經(jīng)完成兩天了。

×He has finished my task for two days.

√He has been finished my task for two days.

√He has been two days since I finished my task.

2.容易錯(cuò)誤地給現(xiàn)在完成時(shí)加明確的過去時(shí)間狀語。如果要強(qiáng)調(diào)明確的過去時(shí)間，一般都必須改為過去一般時(shí)。

例如：

他們昨天下午就已經(jīng)到達(dá)這里。

×They have arrived here yesterday afternoon.

√They arrived here yesterday afternoon.

我在1995年就已經(jīng)畢業(yè)了。

×I have graduated in 1995.

√I graduated in 1995.

3.有些地點(diǎn)狀語也不能用于現(xiàn)在完成時(shí)中，因?yàn)楝F(xiàn)在完成時(shí)不強(qiáng)調(diào)地點(diǎn)狀語。若有地點(diǎn)狀語，通常要改為過去一般時(shí)。

我已經(jīng)在上海見過小王。

×I have met Xiao Li in Shanghai.

√I met Xiao Li in Shanghai.

他在家鄉(xiāng)就已把發(fā)型改了。

×He has changed his hairstyle in her hometown.
