I think this book is better than the one I read last time.

(2) it 所代替的是前面提到的同一事物，既可以代替可数名词，也可以代替不可数名词；还可以代替上文中的某个句子或句中的一部分。

eg.I need the bike but I have no money to buy it.

He has gone out of his way to help us. We won't forget it.

(3)that 也可以代替前面所提到过的名词，用与于特指，相当于"the + 名词"，其复数形式为those。

eg. Her attitude to me was that of a friend.

The problem is more difficult than those we have met with before.
