题目内容
2.In most middle schools,students never seem to have time to enjoy themselves until after 6:00pm,_____ many adults have gone home.( )A. | whose time | B. | that time | C. | by which time | D. | on which time |
分析 句意:在大多数中学,孩子们(学生们)似乎直到晚上6点才有时间开心地玩,而到那个时候,许多大人们(成年人)都已回家了.
解答 答案C.
分析句子结构可知,逗号之前是主句,逗号之后是非限制性定语从句.句中先行词是主句中的"after 6:00pm",根据句意"而到那个时候"可知,这里是由by which time 引出的是一个非限制性定语从句,其中 by which time 相当于 and by that time many adults have gone home,因此C项符合语境,故选C.
点评 本题考查非限制性定语从句.解答此类题目首先要分析句子结构,非限制性定语从句中逗号是一个明显的标志,然后分析非限制性定语从句中的成分,如果缺成分用关系代词,如果不缺成分用关系副词.
