题目内容
13.-At present,one of the best ways to study is working in groups.-More chances ________ to students to learn from each other.( )
| A. | offer | B. | are offered | C. | have offered | D. | are offering |
分析 目前,最好的学习方式之一是小组合作.给学生们提供了更多互相学习的机会.
解答 答案:B此题中主语是谓语动词的承受者,即主语more chances与谓语动词offer是被动的关系;结合上文时间状语at present可知,此句要用一般现在时态.故谓语动词要用一般现在时的被动语态.一般现在时的被动语态的结构是is/am/are+动词的过去分词,根据主语是more chances为名词复数故动词be 为are,offer的过去分词为offered,故选B.
点评 在完成此类题目时,要通过主语与谓语动词之间的关系来判断句子的语态,是主动结构还是被动结构;然后再根据时间状语判断句子的时态,即可选出正确答案
