     [1] What do you do to take care of the books in your library? Some collectors refuse to read the

books in their collection; so the books remain in good condition. Others buy two copies of a book: they

read one, and leave the other untouched. However, many readers must read their books, but they still want to protect and care for the volumes. Here are some tips to remember if you want your books to remain in good condition.

     [2] Avoid Writing. You may have been told to write in your books, or even to underline words,

phrases, and paragraphs. But if you plan to keep the book, add it to your library, or even sell it - don't

write in the book. The ink may damage your book forever. Use a notebook to take notes or use pieces of paper. If you are required to write in your book, use a pencil, and remove the markings later.

     [3] Avoid Food and Drinks. Food and drinks are things that may be dangerous to your books, so the

best way is to avoid eating or drinking while you read. If you need to read while you eat, make sure your

fingers are clean and dry as you hold the book or turn the pages. Also, keep the book well away from the

food and drinks.

     [4] Take Care. When you handle your book, hold it with care. When you read the book, don't fold

down the corners of the pages (use a bookmark instead). Don't place your book with the book open,

face-down. You'd better use a book cover to keep your book in the best condition.

     [5] Put it on the Shelf. If you want to take care of your books, keep your books on a shelf when

____________. But, also, take care that the books should be placed in an upright(竖亍钴)position.
