Most scientists agree that every modern house has some kind of indoor pollution, which can cause a person to feel tired, to suffer eye pain, headache and other problems. Believe it or not, some pollutants can cause breathing diseases of blood and even cancer.
What made us feel relieved is that there’s growing concern about the problem now. It is true that when builders began constructing houses and offices they did not want to waste energy. To do this they built buildings that prevented or limited the flow of air between inside and outside. For the same purpose, man-made building materials were employed to build houses, which are now known to let out some harmful gases.
Facing the serious challenge, scientists have been searching for a way to handle the problem. To everyone’s delight, they discovered a natural pollution control system for building—green plants, though they do not really know how plants control air pollution. Scientists suppose that a plant’s leaves absorb or take in the pollutants and in exchange gives out oxygen through its leaves and tiny organizations on its roots. Therefore they recommend that all buildings should have one large plant or several small plants inside for every nine square meters of space. Because studies indicate that different plants absorb different chemicals, the most effective way to clean the air is to use different kinds of plants. In conclusion, having green plants inside your house can make it a prettier and healthier place. Why not try?

To learn more about how captivity(监禁) affects elephants, a team of international scientists led by Mason, a biologist, compared the life spans of female elephants born in zoos with female elephants living outdoors in the wild. Zoos keep detailed records of all the animals in their care, documenting factors such as birth dates, illnesses, weight and death. These records made it possible for the researchers to analyze 40 years of data on 800 elephants in zoos.
The team found that female elephants born in zoos lived an average of 16.9 years. Their wild counterparts（同类事物） who died of natural causes lived an average of 56 years——more than three times as long.
Scientists don"t yet know for sure why wild elephants seem to live so much better than their zoo-raised counterparts. Mason thinks stress and obesity(肥胖) may be to blame. Zoo elephants don"t get the same kind of exercise as they do in the wild, and most are very fat. Elephant social lives are also much different in zoos than in the wild, where they live in large groups.
Another finding from the study showed that elephants born in zoos were more likely to die earlier than elephants captured in the wild and brought to zoos. Mason suggests stress in the mothers in zoos might cause them to have babies that are less likely to survive.
The study raises some questions about acquiring more elephants to keep in zoos. While some threatened and endangered species living in zoos reproduce successfully and keep healthy populations, that doesn"t appear to be the case with elephants.
小题1:The text tells us that zoo elephants are different from other zoo animals because they________
| A．develop health problems. |
| B．1ive to a ripe old age. |
| C．are not afraid of predators. |
| D．have difficulty eating food. |
| A．Female elephants live longer than male elephants. |
| B．Female zoo elephants die earlier than their wild counterparts. |
| C．Female zoo elephants live longer than their wild counterparts. |
| D．Both elephants in zoos and those in the wild live in large herds. |
| A．Zoo-born elephants should be attended more carefully |
| B．Elephants are no longer an endangered species. |
| C．It may not be a wise policy to keep elephants in the zoo. |
| D．Zoos should keep more animals except elephants. |
| A．Comparison between two species of elephants |
| B．Longer lives for wild elephants |
| C．Female elephants suffer from poor health. |
| D．Longer lives for zoo animals. |
There are four main food groups altogether. The dairy group has food like milk, cheese and sour milk. The other three groups are the meat and fish group, the fruit and vegetable group, and the bread and rice group. Each meal should have at least one food from all four main groups. With all these food together, you will be given enough energy during the day.
It is easy to get into bad eating habits. You may eat your breakfast in a hurry to get to school on time. Or you may not have time for a good lunch. It may seem easy to finish your supper with fish and chips all the time. But you will find yourself tired in these days and you can not think quickly.
Watching what you eat will help keep your body healthy and strong. It is also good to take some exercise. It will help you eat more if you take a walk or play games in the open air. Having a good eating habit with some exercise is the key to your health.
小题1:Which of the following diets do you think is the best one?
| A．Eggs, tomatoes and chicken. |
| B．Milk, bread, cabbages and beef. |
| C．Corn, fish, cream and pork. |
| D．Rice, bean curd（豆腐）, apples, fish and chicken. |
| A．Going to school without any breakfast |
| B．Eating fish and chips for supper all the time. |
| C．Eating your lunch in a very short time. |
| D．Having at least one food from all four groups in each meal. |
| A．the food made out of cows such as milk and butter |
| B．the shop that sells milk and butter |
| C．a farm where cows are kept |
| D．a place where milk products are made. |
| A．enough energy helps people think more quickly |
| B．taking exercise can keep your body strong |
| C．every person needs food to grow well |
| D．right kind of food with exercise will keep you healthy |
Animals are natural resources(资源) that people have wasted all through our history.
Animals have been killed for their fur and feathers(羽毛), for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the earth forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger.
Why should people care? Because we need animals. And because once they are gone, there will never be any more.
Animals are more than just beautiful or interesting. They are more than just a source of food. Every animal has its place in the balance (平衡) of nature. Destroying one kind of animal can create many problems.
For example, when farmers killed large numbers of hawks(鹰), the farmers’ stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice. With no hawks to keep down their numbers, the rats and mice multiplied(繁殖) quickly.
Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger.
Quite a few countries have passed laws. These laws forbid(禁止) the killing of any animal or plant on the danger list. Slowly, the number of some animals in danger is growing.
小题1:Animals are important to us mainly because __________.
| A．they give us a source of food |
| B．they are beautiful and lovely |
| C．they keep the balance of nature |
| D．they give us a lot of pleasure |
| A．About 170 kinds of animals have disappeared forever. |
| B．Thousands of kinds of animals are gone forever. |
| C．A few kinds of animals have died out. |
| D．All kinds of animals are in danger. |
| A．They kill animals for something they need. |
| B．They kill animals to raise some money. |
| C．Animals destroy their natural resources. |
| D．Animals create many problems. |
| A．Animals in danger will be kept away from people. |
| B．Animals in danger will not be killed any more. |
| C．The number of some animals in danger will increase. |

With my load of magazines I headed toward Belleville Avenue. The crowds were there. There were two gas stations on the corner of Belleville and Union. For several hours I made myself highly visible, making sure everyone could see me and the heavy black letters on the bag that said THE SATURDAY EVENING POST. When it was suppertime, I walked back home.
“ How many did you sell, my boy?” my mother asked.
“ None.”
“ Where did you go?”
“ The corner of Belleville and Union Avenues.”
“ What did you do?”
“ Stood on the corner waiting for somebody to buy a Saturday Evening Post.”
“ You just stood there?”
“ Didn’t sell a single one.”
“ My God, Russell!”
Uncle Allen put in, “ Well, I’ve decided to take the Post.” I handed him a copy and he paid me a nickel. It was the first nickel I earned.
Afterwards my mother taught me how to be a salesman. I would have to ring doorbells, address adults with self-confidence, and persuade them by saying that no one, no matter how poor, could afford to be without the Saturday Evening Post in the home.
One day, I told my mother I’d changed my mind. I didn’t want to make a success in the magazine business.
“ If you think you can change your mind like this,” she replied, “ you’ll become a good-for-nothing.” She insisted that, as soon as school was over, I should start ringing doorbells, selling magazines. Whenever I said no, she would scold me.
My mother and I had fought this battle almost as long as I could remember. My mother, dissatisfied with my father’s plain workman’s life, determined that I would not grow up like him and his people. But never did she expect that, forty years later, such a successful journalist as me would go back to her husband’s people for true life and love.
小题1:Why did the boy start his job young?
| A．He wanted to be famous in the future. | B．The job was quite easy for him. |
| C．His mother had high hopes for him. | D．The competition for the job was fierce. |
| A．excited | B．interested | C．ashamed | D．disappointed |
| A．She forced him to continue. | B．She punished him. |
| C．She gave him some money. | D．She changed her plan. |
| A．The early life of a journalist. |
| B．The early success of a journalist. |
| C．The happy childhood of the writer. |
| D．The important role of the writer in his family. |
Languages do not just have different sounds, they are different in many ways. It’s important to master(掌握) the rules for word order in the study of English, too. If the speaker puts words in a wrong order, the listener can’t understand the speaker’s sentence easily. Sometimes when the order of words in an English sentence is changed, the meaning of the sentence changes, But sometimes the order is changed, the meaning of the sentence doesn’t change. Let’s see the difference between the two pairs of sentences.
“She only likes apples.” “Only she likes apples.”
“I have seen the film already.” “I have already seen the film.”
When you are learning English, you must do your best to get the spirit(精神实质) of the language and use it as the English speaker does.
小题1:From the passage we know that _______when we are learning English.
| A．we shouldn’t put every word into our own language |
| B．we should look up every word in the dictionary |
| C．we need to put every word into our own language |
| D．we must read word by word |
| A．difficult to understand different sounds |
| B．necessary to remember the word order |
| C．important to master the rules in different ways |
| D．easy to master the rules for word order |
| A．the meaning of an English sentence always changes with the order of the words |
| B．The order of words can never change the meaning of an English sentence |
| C．sometimes different order of words has a different meaning |
| D．if the order of words is different, the meaning of the sentence must be different |
| A．is the same as “Only she likes apples.” |
| B．is different from “Only she likes apples.” |
| C．means “She likes fruit except apples.” |
| D．means “She doesn’t like apples.” |
