試題分析:考察時(shí)態(tài)和語(yǔ)態(tài)。句意:史密斯先生一直在寫一本為高中生使用的語(yǔ)法書,很快就要完成了。根據(jù)句意說(shuō)明這本書還沒(méi)有寫完,在過(guò)去這段時(shí)間里他一直都在寫。使用現(xiàn)在完成進(jìn)行時(shí)表示從過(guò)去到現(xiàn)在的一段時(shí)間里一直在做的事情,故A正確。
點(diǎn)評(píng):英語(yǔ)中的時(shí)態(tài)主要由動(dòng)詞的形式?jīng)Q定,因此在學(xué)習(xí)英語(yǔ)時(shí)態(tài)時(shí),要注意分析動(dòng)詞形式及具體語(yǔ)境,想象在那個(gè)特定的時(shí)間動(dòng)作所發(fā)生的背景,這個(gè)動(dòng)作是經(jīng)常性動(dòng)作、一般性動(dòng)作、進(jìn)行性動(dòng)作、完成性動(dòng)作還是將要發(fā)生的動(dòng)作。
