一道有关定语从句的高中英语题

The Greens will move into the new house next Monday,( )it will be completely finished.
A.by the time B.by which time C.by that time D.by this time
括号中应选择哪个选项？为什么？这道题在考察什么？

Answer 1

你好！
The Greens will move into the new house next Monday,( B )it will be completely finished.
A.by the time B.by which time C.by that time D.by this time
考点：介词+关系代词引导的定语从句
翻译：格林一家下周一就会搬到新房子里，到那时房子就全建好了。
答案解析：定语从句 by which time it will be completely finished 修饰 next Monday，该从句的完整句是：it will be completely finished by next Monday. 变从句是，将next Monday提前成为先行词，并用关系代词which time (when也可以) 代替原句成分，将介词+关系代词（by which time) 作为引导。

希望对你有帮助。祝你学习进步！

Answer 2

选b,这也是个非限定性定语从句,先行词是前面的整个句子 排除a和d ,by是介词不能用that

Answer 3

选B。考的是非限制性定语从句的引导词，不能用that,只能用which。
