[文法] 關係代名詞的用法

[McCarthy (麥卡錫)]

大家好
請問第一個句子:
This is a topic about which I know very little.
是否可以改成以下2句呢?

1.This is a topic which(that) I know about very little.
2.This is a topic which(that) I know very little about.

------------------------------------------
另外,這二個句子:
This is a good place in which we can sit for a chat.
可以改成以下2句嗎?

3.This is a good place which(that) we can sit in for a chat.
4.This is a good place which(that) we can sit for a chat in.

麻煩大家了,感謝!
