Question

Is this book_____ you bought

Is this book_____ you bought the other day?
A.that Bwhich Cthe one
答案选C，但是为什么不选B 可不可以把它还原成陈述句之后 理解成一个表语从句呢？this book is which you bought the other day .把which you bough理解成表语.....求解

Answer 1

首先，这是一个定语从句，the one 后面其实省略了一个that，that在定语从句中，作为从句中的bought的宾语，可以省略。再者，the one 是特指the other day 这一天借的书，不能省。最后，This is which you bought the other day，是不正确，应该是 This is what you bought the other day。因为which 不仅仅坐表语，还作为 bought 的宾语。

Answer 2

which you bought 的正确用法是
Is this book (the one which) you bought the other day?
which 通常可以省略，所以
正确答案是 C. the one

Answer 3

当你用which后面的句子就变成附加句，整句话的意思变了。
Is this book which you bought the other day? = Is this book? which you bought the other day.

Answer 4

which 不能单独用来指代前面的the book ，其实C选项就像楼上说的，是相当于： the one which, 其中which可以省略，但是你总不能省了 the one, 这样先行词都没了，怎么构成从句。
另外你理解成表语从句，which 应该改为what， bought which 是不合语法的。

Answer 5

如果作表语应该是this book is what you bought the other day .同时 可改写为this book is the one which/that you bought the other day .因为the one 在定语从句中作宾语，which/that 可省略,为this book is the one you bought the other day ,
