不一定,当who在句中作主语时谓语动词要用三单形式,疑问词作主语时,谓语动词一定用单数第三人称形式,叫做“状况不明,视为单数”。当who在句中作宾语时,根据主语的形式决定。
who作表语who后面的动词用什么形式、宾语时,根据主语确定谓语。 如who is he? who are they?who does he work for?who do you work for? 所以who要根据划线的主语的单复数来确定谓语形式。
who在定语从句中用法:
先行词为anyone,one,ones以及先行词为those,he和people时,这些词代替指人,whom在定语从句中指人,“who”和“that”既可作主语又可作宾语(作宾语可以省略,who作宾语变为whom),that可以指人也可以指物,who不可指物。在从句中所起作用如下:
1.Is he the man who/that wants to see you?他是那个想见你的男人吗?(who/that在从句中作主语)
2.He is the man (whom/that) I saw yesterday.他就是我昨天见到的那个人。(whom/that在从句中作宾语)
3.The man whom you spoke to just now is our English teacher.刚刚和你说话的那个男人是我们的英语老师。(whom在从句中作宾语)
注:who在定语从句中指人,作主语和宾语,作宾语时可省略;做及物动词或介词的宾语,可省略。
