He, along with his brothers, ______ how serious the situation is.
A.haven’t realizedB.hasn’t realized
C.don’t realizeD.didn’t realize
B

試題分析:考查時(shí)態(tài)和主謂一致。本題的主語(yǔ)是He, along with his brothers,謂語(yǔ)動(dòng)詞應(yīng)該與he保持一致,故使用單數(shù)的形式。另外本題中沒(méi)有出現(xiàn)過(guò)去時(shí)的時(shí)間狀語(yǔ)。句意:他和他的兄弟已經(jīng)意識(shí)到了情況是多么的嚴(yán)重。根據(jù)句意說(shuō)明使用現(xiàn)在完成時(shí)的時(shí)態(tài)。故B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。
