I'm so tired,I want to find a room to live是填at?
I'm so tired, I want to find a room to live in. 按照习惯我们都会说In the room 而不是at the room. 所以这里要填in.不过这句话有点语法问题.I'm so tired 按照英语语法来说已经是一个简单句了,后面I want to find a room to live in也是一个简单句.两个简单句放在一起,中间用逗号是不符合英语的语法的.这里可以把这两个简单句合并成并列句,或者复合句.
I'm so tired that I want to find a room to live in.
I'm so tired and I want to find a room to live in.
或者中间用分号：I'm so tired; I want to find a room to live in.
