  Do you know sotriething about tree rings (年轮)? Do you know they can tell us what the weather was like, sometimes even hundreds of years ago?

  A tree will grow well in a climate with lots of sunshine and rainfall. And little sunshine or rainfall will limit the growth of a tree. We can see the change of climate by studying the tree rings. For example, to find out the weather of ten years ago, count the rings of a tree from the outside to the inside, if it is near to the eleventh ring, then the climate that year was bad.

  Tree rings are important not only for studying the history of weather but also for studying the history of human. Many centuries ago there lived a lot of people at a place in New Mexico. But now you can find only sand there --- no trees and no people. What happened?

  A scientist studied the rings of dead trees there. He found that the people had to leave because they had cut down all the trees to make fires and buildings. As all the trees had gone, the people there had to move.

  How many books are students allowed to borrow at once? Kindergarten and Grade One:Children are allowed to borrow one book a week.Grade Two and Up:Students in Grade Two and up are allowed to borrow two books a week.

  How long is the loan? Books are loaned for about a week,however the school is on a 5-day cycle.Books are due on the cycle day.A book borrowed on Day 1 is due on the next Day 1,even if it is not the same day of the week.A book borrowed on Tuesday may be due on a Wednesday,if there is a holiday between when the book is borrowed and when it must be returned.

  May I renew my book? Our computer system does not allow us to renew books,so they must be returned and checked out again.We ask students to return their books at the beginning of the day with their bookmark/library card inside and sticking out.We will check the book in and put it aside for the student to get when he returns with his class.

  How much is the fine if I return a book late? There are no fines for children in grades K-6.However students who have an overdue book may not borrow another book.

If I have the right to borrow two books and I have returned one,may I take out another book?

If the book you have left at home is not yet overdue,you may take out another book.However,if it is overdue,you will not be allowed to take out another book.

If you lose a book,we will give you time to look for it.

  Some good places to look for books:

  In another basket in the classroom

  Under a bed

  Under a sofa or chair or cushion

  Behind the couch

In your locker or school bag

  If you can't find the book,we will ask you to pay for it.Since it will probably cost more to replace the book than we originally paid,we will charge you the full replacement cost,including tax and other costs.
