When,What,Where,Which,That引导非限制性定语从句，和引导限制性定语从句时用法有什么不同？在单选题中又该如何区别呢？请老师给予详细的解答！
解题思路： 如下
解题过程：
注意：what不能引导定语从句。
英语语法中的非限制性定语从句 一、 非限制性定语从句通常不能用that引导。如：
1. I like the book, which was bought yesterday. 我喜欢这本书，这是昨天买的。
2. I like the book which / that was bought yesterday. 我喜欢昨天买的那本书。
二、 非限制性定语从句不能用why引导。要用for which代替why。如：
1. I had told them the reason, for which I didn't attend the meeting. 我已经把理由告诉了他们，为此我没有去开会。
2. I had told them the reason why I didn't attend the meeting. 我告诉了他们我不去开会的理由。(限制性定语从句“the reason why...”是常见搭配。)
三、 非限制性定语从句置于句首时，不能用which引导。关系代词as引导非限制性定语从句位置比较灵活，可以放主句前，也可以放主句后。如：
1. As I expected, he didn't believe me. 正如我所预料的，他不相信我。
2. She heard a terrible noise, which brought her heart into her mouth. 她听到一个可怕的声音，这让她把心都提到嗓子眼了。
四、 非限制性定语从句由“介词+关系代词”引导时，其中的关系代词不能用as。如：
1. He bought the car for more than $20,000, with which his father was angry. 他花两万多美元买了这辆车，他父亲对此很生气。
2. I finished my work ahead of time, after which I sat some time reading the newspaper. 我提前干完了我的活，随后我坐着看了一会儿报纸。
五、 在非限制性定语从句中，指人的关系代词作宾语时，只能用宾格whom; 不能用who替换，也不能省略。如：
1. Do you know Tom, whom we talked about? 你认识汤姆吗? 我们谈到过他。
2. This book, which you can get at any bookshop, will give you all the information you need. 这本书会给你提供所有你需要的资料，它在任何一家书店都能买到。(非限制性定语从句中引导词在从句中作宾语，无论指人还是指物都不能省略。)
限制性定语从句和非限制性定语从句的区别：
1) 定语从句有限制性和非限制性两种。限制性定语从句是先行词不可缺少的部分，去掉它主句意思往往不明确；非限制性定语从句是先行词的附加说明，去掉了也不会影响主句的意思，它与主句之间通常用逗号分开，例如：
This is the house which we bought last month. 这是我们上个月买的那幢房子。（限制性）
The house, which we bought last month, is very nice.这幢房子很漂亮，是我们上个月买的。（非限制性）
2) 当先行词是专有名词或物主代词和指示代词所修饰时，其后的定语从句通常是非限制性的，例如：
Charles Smith, who was my former teacher, retired last year. 查理·史密斯去年退休了，他曾经是我的老师。
My house, which I bought last year, has got a lovely garden. 我去年买的的那幢房子带着个漂亮的花园。
This novel, which I have read three times, is very touching. 这本小说很动人，我已经读了三遍。
3) 非限制性定语从句还能将整个主句作为先行词, 对其进行修饰, 这时从句谓语动词要用第三人称单数，例如：
He seems not to have grasped what I meant, which greatly upsets me. 他似乎没抓住我的意思，这使我心烦。
Liquid water changes to vapor, which is called evaporation. 液态水变为蒸汽，这就叫做蒸发。
说明：关系代词that和关系副词why不能引导非限制性定语从句。
最终答案：略
