题目内容
13.This machine needs once a year in order to work properly.( )| A. | to check | B. | checking | C. | check | D. | checked |
分析 这台机器需要每年检修一次,以便于能够正常工作.
解答 答案:B.
根据语境推测句意是"这台机器需要每年检修一次,以便于能够正常工作.",根据句子中的need 判断此题考查句式"需要做某事"; 由于主语this machine和动词check之间是动宾关系,所以应该是need doing 所以选B.
点评 need to do 表示主动意义,need 接动名词主动形式,表示被动意义、这时动名词和主语之间有动宾关系,need doing 可转换为 need to be done 结构,意思相同.
