题目内容
20.______a certain doubt among the parents as to the necessity of children's doing so much home-work.( )A. | There existed | B. | There had | C. | It existed | D. | It had |
分析 父母对孩子做这么多家庭作业的必要性存在疑问.
解答 A 考查固定句型.there be句型本身就是完全倒装句.其中be可以换成其他动词如;there lives/lived…;there lies/lay…;there stands/stood;there exists/existed等等,用现在时还是过去时是根据句子的时态要求而定的.根据句意:父母对孩子做这么多家庭作业的必要性存在疑问.所以答案选A.
点评 "There be"是英语中最常见的又是非常重要的句型,意思是"有",表示"人或事物的存在"或"某地有某物",不管在口语中还是在书面语中,there be 句型的使用频率是很高的.但是对there be句型的多变的特点及其特殊结构的复杂性的了解,是解答there be 句型的关键.
