He hit him on the head with a book
用书───Books;头───head
My suitcase was full of books.───我的提箱装满了书。
These books must be very old.───这些书一定年头很久了。
His books are not well known.───他写的书不太有名。
As the books began to accumulate, the librarian felt obliged to throw some useless books away, for there was no enough room in the library.───随着书越来越多，图书管理员感到有必要把没用的书扔掉，因为图书馆里的空间不足。
It's amazing, it's always been a dream to come out here, you see all the stuff on TV, you read it in books, but it becomes reality.───来到这里一直是我的梦想，你从前都是在电视上看到这些景象，在书里读到它们，但现在都成真了。
When you walk into the bookstore and see a table filled with books on dieting , you know it must be January.───当你走进书店，映入眼帘的是琳琅满目的减肥书，你就能肯定这一定是一月份。
Read not books alone, but men.
Books, like friends, should be few and well chosen.
Books and friends should be few but good.
The books sat unread on the shelf for years.
My library books are a week overdue.
