Thats bad for the soil. But this kind of pollution is difficult to stop.Hope for the futureThese problems are very serious for our future, so all of us should do something to improve our environment.

What do you hear? You may hear many different sounds. Some of those sounds may be noise. Noise is a loud or unwanted sound.Noise can be caused by many kinds of machines, such as motorcycles, jet planes (喷气式飞机), farm tractors, and power motors. And, to some people, rock music is also a noise.What happens to people who live near noisy machines or use them over a period of time? Doctors have found that these people have trouble in sleeping. And most importantly, constant (连续的) loud noise can cause loss of hearing.Scientists use a unit of measure called a decibel(分贝) to measure the loudness of a sound. The sound of a quiet room, for example, measures 35 decibels. Talking measures between 40 and 65 decibels. Sounds from traffic and from some rock bands measure over 120 decibels. Noise at such high level causes the greatest hearing loss.根据短文内容，判断正(T)误(F)。( )31.According to the passage, noise is all sounds that you can hear.( )32.A “decibel” is a machine that makes loud noise.( )33.Loud noise can help people sleep better.( )34.Not all people think that rock music is a noise.( )35.We can infer (推断) from the passage that noise is a serious problem.（C）Trees are useful to man in three very important ways.The first important way is that they provide man with food, wood and other products（产品）. Trees provide man and animals with food to live on the earth. Its not easy for man to live on the earth without trees.The second important way is that trees give us shade. On a hot summer day, people are eager to (急于) have a rest under the shade of a tree after they have walked a long way. You can imagine how important the shade of a tree is to man and animals.The third important way is that trees help to prevent droughts and floods. However, in many parts of the world, man has not realized the third important way. He has cut trees down in large numbers. In the end, he finds that he has lost the best friends he had.根据短文内容填空，每空一词。36.Trees give food to _ man _ animals.37.Trees are _ and _ to man.38.On a _ summer day, if we sit under the _ of a tree, we can feel quite cool.39.In many parts of the world, man has not realized that trees help to prevent _ and _.40.If we dont want to lose our best friendstrees, we must stop others from _ _ too many of them.(D) In western countries, more and more foods have additives in them. What are additives? Additives are chemicals which are put into foods to give them color and taste, to stop them going bad and so on. But doctors say that some additives can be very bad for our health.Now lets look at how additives can be bad for our health. Take this for example, a little English girl called Sally Jones is two years old and quite ordinary (普通的). But when she was younger, she never went to sleep at night. She never got tired. Her parents were very worried. Finally, Sallys parents took her to a special doctor.The doctor said that she must never eat food with additives in it. He was sure that the additives had a very bad effect on her body, and made her too active. He was quite correct. As soon as Sally started to eat foods with no additives, she began to sleep well at night.Now she is the same as other little girls, except that she cant eat many foods that other children love, such as ice-creams, because they have additives in them.根据短文内容，回答下列问题。51.Whats the Chinese meaning of the word “additive”?_52.What are the functions (功能) of the additives?_53.Did Sally like sleeping at night before she went to see the doctor?_54.What happened to Sally when she stopped eating the foods with additives?_55.Why cant Sally eat ice-creams?_五.书面表达。（10分）人类只有一个地球。根据提示，以“Saving the Earth”为题，写一篇80词左右的短文。提示: 1.如何保护环境已成为世界最大难题之一；2.各种污染破坏环境，损害健康；3.不要乱倒垃圾，乱排废水；4.我们应该保护环境，使我们的家园更加美丽。
