为什么表语从句中who+whom+which+不能既连接从句又充当主语宾语
您好,表语从句中的 who,whom,which 是连接代词,在句中可以充当主语、宾语、表语和定语的。比如:
1)The question is who will clean the room.
这里的 who 引导的就是(表语从句),在(表语从句)中充当(主语),此时 who 既是引导词,又充当主语。
2)The problem is whom we can trust.
这里的 whom 引导的也是(表语从句),在(表语从句)中充当(宾语),此时 whom 既是引导词,又充当宾语。
3)The issue at hand is which of us should finish the work.
这里的 which 引导的也是(表语从句),在(表语从句)中充当(主语),此时 which 既是引导词,又充当主语。
4)The argument is which one we are to buy for her as a birthday present.
这里的 which 引导的也是(表语从句),在(表语从句)中充当(定语),修饰宾语 one。
引导表语从句的连接代词除了 who, whom, which 以外,还有 whose,what,whoever,whomever,whichever,whatever等共9个引导词可以使用。
