who在名词性从句中有表示疑问“谁”的意思(此点与定从不同)
如:The question is who will be the next speaker. 问题是谁接着发言。
what无疑问语气,如:That’s just what I want. 这正是我想要的。
特别注意what可相当于the thing/time/person/place/amount/number that
其次,what并不一定指物,如He is ____is known as a hacker- he likes to show off on the Internet and attack websites. 此处用what,因为无疑问语气
望采纳
连接代词在句中既保留自己的疑问含义、又起连接作用,在从句中充当主语的成分。who指人,what指物。
What he wants to tell us is not clear. 他要跟我们说什么,还不清楚。
Who will win the match is still unknown. 谁能赢得这场比赛还不得而知。
Theshopkeeperdidnotwanttosellfor______hethoughtwasnotenough.(2005山东)A.whereB.howC.whatD.which【答案及解析】C本题考查关系代词的使用。what在引导名词性从句时“身兼二职”,既起连结作用,又在从句中作一个句子成分,其他几个选项绝无此功能。这里名词性从句whathethoughtwasnotenough.做介词for的宾语。
