英语选择When asked what they would volunteer to do
When asked what they would volunteer to do,（）said they were willing to do something they could.
A。half of which B.half of whom
请解释一下
答
B 后面那句话的主语是人，所以用whom。人才能said啊。
老师祝你学习进步！
望采纳，多谢！^_^
答
答案是half of them,前面有when从句，后面是主句，要用them 做主语的
答
选B，先行词是人
答
应该选C.half of them。一眼上去容易误解为是定语从句，其实不是。逗号前面是when引导的一个时间状语从句，缺少的是主语。
答
用half of whom ,whom做of的宾语,翻译为他们之中一半的人.
