what changes后面用单数还是复数?
看这句
we hope that the robot fish can find what changes ___(take)place in the sea and report the information to people.
填的为什么是has taken place而不是have taken place.
还有,changes要用单数还是复数
单复数和what有关吗,暂时就这些
看这句
we hope that the robot fish can find what changes ___(take)place in the sea and report the information to people.
填的为什么是has taken place而不是have taken place.
还有,changes要用单数还是复数
单复数和what有关吗,暂时就这些
这句话的结构如下： 主句：We hope宾语从句：that the robot fish can find what changes ___(take) place in the sea and report the information to people. 其中—— 【嵌套主句】he robot fish can find 【嵌套宾语从句】what changes ___ (take) place in the sea and report the information to people 嵌套宾语从句中的 what是形容词,用作定语,修饰后面的名词 changes,它与被修饰名词的单复数没有关系. what 修饰复数名词 changes 的意思是“一些什么样的变化”,后面应该跟动词原形与复数名词的 changes 保持数的一致.就本题来说,因为宾语从句的主语是复数,所以要用 have taken,即 We hope that the robot fish can find what [changes (have taken )] place in the sea and report the information to people.what 修饰单数名词 change 的意思是“一个什么样的变化”,后面应该跟单数第三人称的动词与单数名词 change 保持数的一致.如果用 has taken,那么应该把本题的 changes 改为单数,即We hope that the robot fish can find what [change (has take) ] place in the sea and report the information to people.
再问： Great changes （）in China since the People‘s Republic of China was founded in 1949 这句也有人说填has taken place，他认为changes做主语可用单数也可用复数， 到底是怎么一回事呢
