All living things on the earth need other living things to live with.  1  Sometimes one living thing kills
another. Each kind of life eats another kind of life in order to live, and together they form a food chain
(食物链).  2  while others are not. But all food chains begin with the sun, and all food chains become
broken if one of the links disappears.
     All life needs sunlight to live on.  3  They make food from sunlight, water, air and so on. Animals can
only use the sun's energy after it has been changed into food by plants. Some animals feed directly on plants.
Others eat smaller animals. Meat-eating animals are only eating plants indirectly. 
      4  We are members of many food chains. We eat wheat, rice, vegetables, fruit and so on. We also eat
meat and drink milk. But people often break up the food chains. They kill wild animals. They also make rivers,
lakes and seas dirty.  5  the fish in them cannot be killed. If people eat the fish, they will get strange
diseases. Each form of life is linked to all the others. Breaking the links puts all life in danger.
A. When these rivers, lakes and seas are polluted,
B.  But only plants can use sunlight directly.
C.  Some food chains are simple,
D. What about human beings?
E.  Nothing lives alone.

Dear Liu Mei,
     I have got a chance (机会) to travel to USA. I am very happy. I went to USA by plane with my
parents. This is the first time for me to go abroad (出国). So I felt exciting. In America, I have learnt
many methods (方法) to cook western food such as smoothie or milk shake. And also learned a lot
about American holidays.
     Children in America like Halloween very much. In the evening on the 31st of October, they put on
special clothes. Sometimes they dress like witches and ghosts. sometimes they dress like kings and
queens. They go to their neighbor's house and knock at the door. The neighbor opens the door. The
children say, "Trick or treat!" The neighbor gives them  chocolate or some fruit. Sometimes people
don't give the children any food. Then the children play a trick on them. They put soap on their windows. Children like this special day. They like their large bags of sweets.
     I hope that you can come to America quickly. Then I will take you to visit many interesting places.
                                                                                                                            Yours,
                                                                                                                             Lin Lin
