Question

The weather was very sunny the following day, ___

The weather was very sunny the following day, _______ was what we had expected.
这个明显是空格处作非限制性定语从句的主语，答案填了which。但是这句难道不是这样翻译吗？
「第二天的天气晴朗，正如我们所预期的那样。」
这样的话，主句和从句就有了“正如”的关系，为什么不能填as？是答案给漏了吗？

Answer 1

也可以填as 原因如下：
( As引导的非限制性定语从句指表示积极的意义，与主句是顺理成章的关系，绝不能与之矛盾。若非限制性定语从句表示一种消极的意义，则只用which。如：

He has succeeded in his career, as / which we all hope. 他在事业中成功了，这正是我们大家所希望的。

Her grandma died last week, which made her very sad. 她的奶奶逝世了，这使得她很悲伤。

Answer 2

which不是做主语了吗代替天气好的这种情况，要是as的话可以作主语吗，反正我感觉用as的话怪怪的

追问

as可以引导非限制性定语从句，能做主语宾语表语啊

追答

我给你搜了一下.当从句的谓语动词是be或相当于联系动词的seem, become等时，可
用as或which作主语。但当从句的谓语是行为动词时，只能用which作主语。例如：
He married her, as (正确) was / seemed natural. Which （正确） He saw the girl, as (错误) delighted him. Which （正确
AS;WHICH引导一个非限制性的定语从句，表示主句整句话的内容，AS代表整个句子内容，并在定语从句中充法主语时，从句的谓语动词必须是系动词，若定语从句的谓语动词是行为动词时，只能用WHICH来引导定语从句
My
sister is so beautiful as your sister.
It rained hard yesterday ,which
perevented me from going to the
park.
AS引导非限制性定语从句，可以代替主句的全部或部分内容，常表示说话人关于说话人的依据、态度、评论、看法，常译成
正如.....一样，好像.....一样，定语从句AS可以放于句首，句中、句末
