问题: choose*_*
1. Many things ____ impossible in the past are common today. A considered B being considered C considering 2. the noise of desks ___ could be heard out in the street. A being opened and closed B opened and closed C to be opened and closed (为什么两个都选A)
解答:
1. Many things ____ impossible in the past are common today. A considered B being considered C considering
considered为过去分词,相当于which were considered; 在定语从句中,consider与many things之间的关系为被动(动宾),所以通常选择过去分词来做定语.
2. the noise of desks ___ could be heard out in the street. A being opened and closed B opened and closed C to be opened and closed
这几个选择都用动词的被动形式(过去分词)来做定语;但是还是有区别的.首先,C用不定式形式常用于表示将来; B是可以完成句子的,但是A是"最佳": B表示"被开、关的桌子的声音",A表示"正在被开、关的桌子的声音".
