We_______on this project for four hours. Let’s have a rest.
A.a(chǎn)re working | B.have been working | C.worked | D.had worked |
B
解析試題分析:考查時態(tài)。本題的關(guān)鍵詞是for four hours,描述的是聯(lián)想工作了4個小時,通常與現(xiàn)在完成進(jìn)行時連用。句意:我們已經(jīng)連續(xù)工作了4個小時了,讓我們休息一下吧!現(xiàn)在完成進(jìn)行時表示動作從過去開始,一直持續(xù)到現(xiàn)在,而且強(qiáng)調(diào)正在發(fā)生。故B正確。
考點:考查時態(tài)
點評:英語中的時態(tài)主要由動詞的形式?jīng)Q定,因此在學(xué)習(xí)英語時態(tài)時,要注意分析動詞形式及具體語境,想象在那個特定的時間動作所發(fā)生的背景,這個動作是經(jīng)常性動作、一般性動作、進(jìn)行性動作、完成性動作還是將要發(fā)生的動作。
