When the lazy days of summer arrive and the schedule is filled with swimming, camp, and family vacations, it can be a challenge to find time for learning. But kids' reading skills don't have to grow cold once school's out. Here are some ways to make reading a natural part of their summer fun：
Explore your library. Visit your local library to borrow books and magazines that your kids haven't seen before. Many libraries have summer reading programs, book clubs, and reading contests (竞赛)for even the youngest borrowers. With a new library card，a child will feel extra grown­up by borrowing books.
Read on the road. Going on a long car trip？Make sure there are some books at the back seat. When you stop driving, read the books aloud. Get some audio books in libraries and listen to them together during driving time. Make your own books. Pick one of your family's favorite parts of summer — whether it's baseball, ice cream, or the pool — and have your child draw pictures of it or cut out pictures from magazines. Stick(粘贴)the pictures onto paper to make a booklet(小册子) and write text for it. When you're done, read the book together. Reread it whenever you like! Keep in touch. Kids don't have to go away to write about summer vacation. Even if your family stays home，they can send postcards to tell friends and relatives about their adventures. Ask a relative to be your child's pen pal and encourage them to write each week. Keep up the reading habits. Even if everything else changes during the summer，keep up the reading habits around your house. Read with your kids every day—whether it's just before bedtime or under a shady tree on a lazy afternoon. And don't forget to take a book to the beach！Just brush the sand off the pages — it's no sweat!
5．The purpose of the passage is to ________.
A. encourage parents to read
B. give advice on raising kids
C. raise a good summer reader
D. suggest places for vacations

6．If you drive on a long trip in summer, you can ________.
A. visit the local library and join book clubs
B. borrow some audio books to listen to
C. keep in touch with friends by sending postcards
D. read your own picture books with your son
答案与解析　B　文章第三段中可以找到答案，B项正确。
7．By saying “Just brush the sand off the pages — it's no sweat”， the author means ________.
A. taking away the sand on the book is very difficult
B. a special book is needed when you're reading on the beach
C. one can remove the sand on the book with a brush easily
D. there's no trouble reading even on the beach
答案与解析　D　文章最终一段说无论是在睡前、树荫下，还是在沙滩上都可以阅读。即使在沙滩上，“阅读只是用手拂去书上的沙粒——根本不费劲！”。D项正确。
8．Who are the possible readers of the passage?
