         If you don't use your arms and legs for some time, they  1  (become) weak. When you start using
them again, they slowly become strong again. Everyone   2   (know) that. Yet many people don't seem to
know that memory  3  (work) in the same way.
        When someone says that he has a good memory, he really means that he keeps his memory in practice
by using it. When someone says his memory is poor, he really means that he 
 4   ( not give) it enough chance to become strong.
        If a friend says that his arms and legs are weak, we know that it is his own fault. (错误) But if he tells
us that he has a poor memory, many of us think his parents may   5  (blame), few of us  6  (know) that it

     1970 was the World Conservation (保护) Year. The United Nations wanted everyone to know that the
world is in danger. They hoped that governments (政府) would act quickly in order to conserve nature. Here
is one example of the problems. At one time there were 1 300 different plants, trees and flowers in Holland,
but now only 860 remain (留下). The others have been destroyed (毁灭) by modern man and his technology
(技术). We are changing the earth, the air, the water, and everything that grows and lives. We can't live
without these things. If we go on like this, we shall destroy ourselves.
     What will happen in the future? Perhaps it is more important to ask "What must we do now?" The people
who will be living in the world of tomorrow are the young people today. A lot of them know that conservation
is necessary. Many are helping save our world. They plant trees, protect wild animals, and so on. In a small
town in the United States a large group of girls cleaned the 11 kilometer-long banks of the river. Young people
may hear about conservation through a record called "NO ONE'S GOING TO CHANGE OUR WORLD".  It
was made by the Beatles, Cliff Richard and other singers. The money from it will help to conserve wild
animals.

     Some people may think too much sunlight can lead to cancer, so they always keep themselves away
from sunlight. But experts believe that proper exposure (暴露) to sunlight is good for us.
     For example, scientists think sunlight can help stop some diseases. They say that wearing sunscreen
(防晒油) all the time makes the body short of vitamin D.
     Vitamin D in fact stops us from more than 25 diseases and keeps bones and teeth healthy. However,
around 60% of the population are short of vitamin D in their blood. One of the easiest ways to get it is to
expose your skin to sunlight. Your body makes vitamin D from the sun faster than it takes in from food.
What's more, safely getting enough sunlight can make you look younger.
     However, not everybody likes sunlight. Some people should not be exposed to the sun without a strong
sun protection. Experts advise that just ten minutes of daily exposure to sunlight should be enough to give
us vitamin D we need.
