语法与词汇
The boy spent as much time watching TV as he______ studying.
【正确答案】
D
【答案解析】在比较状语从句中助动词或情态动词应和主句谓语动词相符合。在这里did用以代替主句中的 spent time。例如:We,too,born to freedom and believing in freedom,are willing to fight to maintain freedom.We,and all others who believe as deeply as we do,would rather die on our feet than live on our knees.我们也是生来自由、坚信自由的,我们愿为捍卫自由而战。我们,还有同我们一样深信自由的人们,宁愿站着死,也不愿跪着生。
