Question

两道英语选择题，帮我将详细一点 超谢谢！

1.If the work____by the end of the week is delayed ,the meeting will have to be put off.
A.will have been finished
B.to be finished
C.is finished
D.has been finished

定语从句
2.The house_____the windows face east in my grandma's
A.of that
B.of which
C.which
D.whose

对于第2个问题，是选B，1.为什么选B？2.老师说如果选D后面应该接名词（whose+n),那么是不是把“house_____the windows ”中的"the"去掉就可以选D了？3.on which和in which和at which 有什么区别和相同点?
列：Mary is playing in the garden,in which there are many trees and flowers 中的in which 用at which 代替行不行？为什么？
...问题有点多 希望大家耐心帮帮我...
多谢了 在线等 好的追加分。

Answer 1

第2题若去掉the可以用whose
Mary一句中which指代garden，in the garden是固定搭配
以上仅供参考
