这两个词的区别我懂，"Which"用于非限定性从句，提供额外的信息，通常用逗号与主句隔开。"That"用于限定性从句，提供必要的关键信息，不使用逗号分隔。给大家简单总结了两个词的含义、发音以及用法，先大概的了解一下~~
接下来让我们看下which和that的其他区别：
1. "Which"和"that"在限定性和非限定性从句中的使用：
- "Which"用于非限定性从句，提供额外的信息，通常用逗号与主句隔开。
- "That"用于限定性从句，提供必要的关键信息，不使用逗号分隔。
例句：
- I have two dogs, which are both rescue animals.
（我有两只狗，它们都是被救助的动物。）
- The book that I bought yesterday is really interesting.
（我昨天买的那本书非常有趣。）
2. "Which"和"that"在修饰物品时的区别：
- "Which"用于修饰具体的物体，无论是生物还是非生物，可以替代整个从句。
- "That"用于修饰特定的物体，通常用于指示或强调特定的人或事物。
例句：
- I found my necklace, which was missing for a week.
（我找到了我的项链，已经失踪了一周了。）
- Pass me the pen that is on the table.
（把桌子上的笔给我。）
3. "Which"和"that"在修饰人时的区别：
- "Which"不常用于修饰人，除非与非限定性从句结合使用，强调陈述的信息。
- "That"通常用于修饰人时，提供关键的身份或特征信息。
例句：
- She is the doctor which/that I saw at the hospital yesterday.
（她是我昨天在医院见到的那位医生。）
- The man that I met at the party is a famous actor.
（我在派对上遇到的那个人是一位著名的演员。）
4. "Which"和"that"在修饰抽象概念时的区别：
- "Which"通常用于修饰抽象概念，强调对整个情况或情感的陈述。
- "That"同样可用于修饰抽象概念，但更常用于指示某一特定的方面或细节。
例句：
- They had a great time at the party, which made them very happy.
（他们在派对上玩得很开心，这让他们非常快乐。）
- The fact that she won the competition surprised everyone.
（她赢得比赛的事实让每个人都感到惊讶。）
5. "Which"和"that"在非限定性从句中的主观倾向：
- "Which"在非限定性从句中有一种较为客观的倾向，提供额外的信息，不强调主观观点。
- "That"在非限定性从句中有一种较为主观的倾向，强调陈述的事实或个人观点。
例句：
- My car, which is black, needs to be cleaned.
（我的车是黑色的，需要清洁。）
- She made a statement that she would never forget.
（她发表了一番话，她将永远不会忘记。）
which可以引导非限定性定语从句，如果去掉which，主句的意思仍然清楚。that则用于引导限定性定语从句，如果去掉that，主句的意思就不完整。这里就给大家总结了一个只用that不用which的表格，可以先简单了解一下先：
区别一：限定性和非限定性定语从句的区别
which可以引导非限定性定语从句，如果去掉which，主句的意思仍然清楚。that则用于引导限定性定语从句，如果去掉that，主句的意思就不完整。
例句：
①The book, which is on the table, is mine. 那本在桌子上的书是我的。
②The book that is on the table is mine. 那本在桌子上的书是我的。
区别二：与介词的搭配不同
which可以和介词一起使用在句尾，而that不能和介词一起使用在句尾。
例句：
①The chair on which you are sitting is broken. 你坐的那把椅子是坏的。
②The chair that you are sitting on is broken. 你坐的那把椅子是坏的。
区别三：指代对象不同
which和that都可以指代物，但在指代人时，只能使用that。
例句：
①The car which is parked outside is mine. 停在外面的那辆车是我的。
②The man that helped me is my teacher. 帮助我的那个人是我的老师。
区别四：在非限定性定语从句中不同
在非限定性定语从句中，只能使用which，不能使用that。
例句：
①My car, which I bought last year, is very comfortable. 我去年买的车非常舒适。
②My brother, that is a doctor, lives in New York. 错误的例句，应该使用who而不是that。
区别五：在同位语从句中的使用
which可以引导同位语从句，而that不能。
例句：
①The fact which we cannot ignore is that he is talented. 我们不能忽视的事实是他很有才华。
②The fact that we cannot ignore is that he is talented. 我们不能忽视的事实是他很有才华。
在定语从句中which和that用法区别：
在定语从句中，which 和that 在指代事物时，一般可以互换使用，但并非在任何情况下都是这样，几种宜用that,而不宜用which 的情况如下：
1、先行词为不定代词,all,much,something,everything,anything,nothing,none,the one等。
2、先行词被only, any, few, little, no, just, very, one of等词修饰时。
3、先行词是序数词时或被序数词修饰时。
4、先行词是最高级或被最高级修饰时。
5、先行词既有人又有物,用which和who都不适合,这时宜用that。
6、被修饰词为数词时。
7、如果有两个从句,其中一个关系代词已用which ,另一个关系代词宜用that,以避免语言的单调或重复。
8、疑问词是who或which,关系代词宜用that,以避免重复。
9、主句是There be 结构,修饰其主句的定语从句宜用that 作关系代词。
10、被修饰成分为表语时,或者关系代词本身是定语从句的表语时,该关系代词宜用that。
定语从句中宜用which而不宜用that 的情况：
1、当关系代词的前面有介词时。
2、在非限制性定语从句中。
3、在一个句子中有两个定语从句,其中一个定语从句的关系代词用了that, 另一个宜用which。
4、当关系代词后面带有插入语时。
5、先行词本身是that, 宜用which。
6、先行词是those+复数名词。
