Twenty students want to attend the class that aims to teach to read first.A. what B. who C. how D. why
我选了B,答案是C

是read fast

没错 how to read first .如何读得最快。read 在这里是不及物动词，

how to read fast 意思是：如何快速阅读 这句话的意思是：20名学生想参加那堂教如何快速阅读的课。 明显不应该用Who，只有how最符合题义了。

C. how

how to read fast 如何读得快 how to read first 如何读得最快 通常（没有语境时），which 不引导名词性从句，但它做定语时可以。即：通常 which 不单独引导名词性从句。 Which book will be given to him is unknown. (主语从句） I don't know which book will be given to him.（宾语从句） His puzzle is which book will be given to him. (表语从句） I will make his puzzle clear which book will be given to him. （同位语从句） There are many books here. I really don't know which (book) I should choose.

因为后面是 read first，所以是how how问的是方式 who问的是人 why问的是原因

你好！ 是不是题干有误？ 应该是 how to read fast 祝你学习愉快！ (*^__^*) 请及时采纳，多谢！ 记得给问豆啊！
