【题目】Nowadays,science is developing at a high speed.With the development of science,many countries have improved their economy and raised their people's living standards.Therefore,science is of great benefit to our daily life.
If we look at the things around us,we'll find how closely our everyday life is related to science.In one case,at home we can turn on the central heating or air conditioner when we feel cold or hot,and we can watch TV or listen to the tape recorder for entertainment,and we can use a gas stove to cook our meals,and we have computers to help us with our work when we are working in the office,and we also have cars,buses,even planes as traffic tools when we go out.All these things are the results of the scientific development,it goes without saying that without science our society cannot make rapid progress and our life cannot be comfortable and convenient.
Now that science is so significant in our daily life,we should try to make as many contributions as possible to the development of science.As college students,we must first of all study hard to gain useful scientific knowledge,and then put what we have learnt into practice.We should make the most of science to serve our society.

【题目】If you can find a tree which has been cut down,you will see many rings,or circles,on the base of the trunk.By learning to read these rings,you can find out about the tree's life.
The number of rings tells you how old the tree is.Each year,new wood is formed on the outside of the tree.This new wood is light in color when the tree is growing in spring and summer,and dark in winter when the tree is not growing much.So,if you count the rings of darkorlight colored wood,you can often find out how old the tree is.
You can also tell which years have been good years and which years have been bad years.When the lightcolored rings are very wide,it means that the tree has been growing quickly that year.If the rings are narrow,it has been growing slowly.If the rings on a tree trunk were greatly magnified,you would be able to see why the rings are lightcolored when the tree is growing quickly and darkcolored when the tree is growing slowly.The tree trunk is made up of microscopic tubes,like some pipes,carrying water from the soil,through the trunk,and up to the leaves.They are wide and thinwalled when the tree is growing quickly and they are carrying a lot of water.They are narrow and stuck together when the tree is not growing so quickly.
When a tree is old,the tubes in the centre of the tree don't carry water.The walls of the tubes have become thick with materials which have stuck along them over the years,forming a kind of wood called“heartwood”.This kind of wood is darker in color than the young,growing wood on the outside of the tree.
You don't very often see whole tree trunks which have been cut across.But once you learn to read a cross section of the wood,you can see much more in wood which has been used to make boxes,houses and other things.
In most wood,instead of seeing the trunk cut across,you are seeing it cut along its length.Because you don't see the whole tree,you can't tell how old it is.
