We had an anxious couple of weeks, ____ for the results of the experiment.
A.waitB.to be waitingC.waitedD.waiting
D

試題分析:考查現(xiàn)在分詞做伴隨狀語(yǔ):句意:我們幾周都很焦慮,等待實(shí)驗(yàn)結(jié)果。逗號(hào)前面的是簡(jiǎn)單句,后面應(yīng)該是非謂語(yǔ)動(dòng)詞做狀語(yǔ),we和wait是主動(dòng)關(guān)系,用現(xiàn)在分詞做伴隨狀語(yǔ)。選D。
點(diǎn)評(píng):當(dāng)分詞做狀語(yǔ)的時(shí)候,如果構(gòu)成分詞的動(dòng)詞與句子的主語(yǔ)構(gòu)成主動(dòng)關(guān)系,就使用現(xiàn)在分詞做狀語(yǔ);當(dāng)二者構(gòu)成被動(dòng)關(guān)系,使用過去分詞做狀語(yǔ)。如果分詞的動(dòng)作發(fā)生在謂語(yǔ)動(dòng)詞之前,就使用分詞的完成式。如果分詞與句子的主語(yǔ)沒有關(guān)系,可以使用狀語(yǔ)從句或者獨(dú)立主格結(jié)構(gòu)。
