16.I was watching TV__________my brother was writing an e-mail at home at this time last night.(  )
A.as soon asB.afterC.untilD.while

分析 昨天晚上這個(gè)時(shí)候,當(dāng)我哥哥在家里寫(xiě)電子郵件的時(shí)候,我在看電視.

解答 答案:D;
根據(jù)設(shè)空處前后的句子都用了過(guò)去進(jìn)行時(shí),可以推斷本句的句意是"昨天晚上這個(gè)時(shí)候,當(dāng)我哥哥在家里寫(xiě)電子郵件的時(shí)候,我在看電視.",表示主句的動(dòng)作和從句的動(dòng)作同時(shí)發(fā)生且持續(xù)進(jìn)行,用while引導(dǎo)時(shí)間狀語(yǔ)從句,while"當(dāng)…時(shí)",通常與延續(xù)性動(dòng)詞連用,表示兩個(gè)動(dòng)作同步發(fā)生,故選D.

點(diǎn)評(píng) 聯(lián)系前后語(yǔ)境,在準(zhǔn)確把握前后句關(guān)系的基礎(chǔ)上,先推測(cè)出大體句意;再結(jié)合關(guān)鍵詞利用其固定用法選出正確答案.
