高一的定语从句could you tell me from --- you borrowed this book这句话填

1、could you tell me from (where) you borrowed this book?
可以用.where 除了副词用法外,还可以用作代词,如：
Where have you come from?你刚从哪里来?——作介词 from 的宾语
Where are you going to?你打算上哪儿去?—— 作介词 to 的 宾语
2、Do you still remember the place (where) we visited last week?
句子中的 place 指的是一块不确定边界的地方,如果用 in which,则表示在一个有确定边界的处所里面,因此此处只能用关系副词 where .
3、it was about 600 years ago (that) the first clock with a face and an hour hand was made.
1）这是一个强调句,此处强调的是时间状语 about 600 years ago,还原回不强调句则为：the first clock with a face and an hour hand was made about 600 years ago.
2）强调句的结构为：it is/was + 强调部分 + that + 其余部分
4、Who (else) knows he wants to make friends with him?
else 常用于疑问代词 who、what 和 which 或不定代词之后表示“另外的.../其他的.../ 别的...”,本句话的意思是“还有谁知道他想和他交朋友呢?”.另如：
* What else did she say?她还说了些什么?
* Would you like anything else to drink?你还要喝点别的什么吗?
