帮忙看看英语作文有没有什么错误

LZ我给你改啦,我觉得不对的地方都在后面用括号加注释了,那个错的地方我都给你改了,有问题的地方也写出来了..您马马虎虎看看吧
The pku library is a six-floor building.Each floor has its special application.
The first floor is used as a（少量词） lastest-book reading room.The books which have become（这个词的过去完成时就是它本身,became一般是过去式） the collection of the library less than a year may be stored（被动式哟） here.These lastest books（去掉横线要不单复数还真不好说） are so hot that we have to return them in two weeks.（句意稍微有点不通,最好再加上个in case other people want to read them.）
The second floor contains an information retrieval reading room and a teacher’s reading room.In the information retrieval reading room we can search on（少介词滴哟） the internet.However the undergraduates are not admitted（多了个d奈） to enter（少动词哟,我给你填上个enter哈） the teacher’s reading room.
The third floor abounds with newspapers and journals.We are not allowed to bring our bags少s into it.
The fourth floor is used as Chinese technology（话说technology就可以,名词做定语嘛） reading room.We can often discover books which are（介个,书是一般存在的东西,不用用过去式滴） published 20 or 30years ago.In some of them we can find “long live Chairman Mao” in bold print.
The fifth floor has（时态不对哦,改成has了） being decorated these days.Probably another information retrieval reading room will be opened to readers next year.
The sixth floor is study hall.Many students used to study there,especially the one（时态前后不对应给你把ones改成one了啊） who wants to pass the entrance（这个词是通道的意思,LZ是不是用错词了） exams for postgraduate schools.
Whether amusement or learning,everyone can get what he needs in pku library.
