题目内容
9.It is important to remember that success __________ a sum of small efforts made each day and often __________ years to achieve.( )A. | is; takes | B. | are; takes | C. | are; take | D. | is; take |
分析 成功是每天做的一点小努力的总和,而且经常要花费多年的时间才能实现,记住这点很重要.
解答 答案:A
and并列两个分句,前一个是主、从复合句,宾语从句的主语是success,为不可数名词,谓语用单数,这样排除B、C两项;后一个分句省略了主语success,谓语仍用第三人称单数,又排除D项,故选A.
点评 考查动词时,根据句子的时态和主语确定动词的形式.
