两道高一英语定语从句问题（求解析）

The reason is ______he is unable to operate the machine.答案是 that 求 主句和从句是什么 That tree,______branches are almost bare ,is vary old .答案是whose 求of which 为什么不对

Answer 1

1.the reason is that....这句话是一个表语从句（放在be动词后面的句子为表语从句），主句为the reason is,从句为that he is unable to operate the machine.
2.第2题答案是whose的原因是：branches的前面没有the，其实就相当于....,whose branches are almost bare,is very old=....,of which the branches are almost bare,is very old(总结为of which the+n=whose +n）

Answer 2

The reason is ______he is unable to operate the machine.答案是 that 求 主句和从句是什么 :是同位语从句，that 在he is unable to operate the machine中不做成分。

That tree,______branches are almost bare ,is vary old .答案是whose 求of which 为什么不对 ：
whose branches= the branches of which

Answer 3

主句是 the reason is…… 从句是 that he is unable to operate the machine
我个人认为是对滴 如果一定要说错的话 也许是因为 如果是of which 应该没有逗号
