In the UK, most children have their lunches at school, but in some schools, parents can choose what their children eat. The children can have a school dinner-a hot, cooked meal; or they can take a packed(包裝的) lunch with them, which usually includes cold food like sandwiches.
Often parents know what their children want. Cath, a mother of three children, told us, “My children have packed lunches because they say they don’t like to have school dinners. So I make three packed lunches every morning.”
However, another mother, Susan, made a different choice. She said, “My daughters have a always had school dinners. I think they probably get healthier food at school than a few sandwiches I make for them.”
But how healthy are school dinners? Kaz, a father, thought poorly of them. He said, “Fizzy(起泡的) drinks were offered and I think there were a lot of chips.”
Jamie Oliver spent a year working in a school kitchen. He was worried about the unhealthy food which included burgers, pizzas and chips. So he tried to cook healthy food such as good stews and curries for the children instead.
So Jamie improved the school dinners, and trained the dinner ladies to cook healthy food in that school. Then he advised the government to improve school food across the country. And it seems that the changes have begun.
Anna, a pupil, told us, “We used to have a fast food window where you got chips and coke, but they stopped that this year. There’s a salad restaurant, which is good, so it’s healthier than it was.”
根據(jù)材料內(nèi)容選擇最佳答案,并將其標(biāo)號填入前括號內(nèi)。

The world itself is becoming much smaller by using modern traffic and modern communication means(交流方式). Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest is pollution. To pollute means to make things dirty. Pollution comes in many ways. We see it, smell it, drink it and even hear it.
Man has been polluting the earth. The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. When the land was used up or the river was dirty in a place, men moved to another place. But this is no longer true. Man is now slowly polluting the whole world.
Air pollution is still the most serious. It’s bad to all living things in the world, but it is not only one kind of pollution. Water pollution kills fish and pollutes drinking water. Noise pollution makes us become angry more easily.
Many countries are making rules to fight against pollution. They stop the people from burning coal in houses and factories in the city, and from blowing dirty smoke into the air.
The pollution of SO2 is now the most dangerous problem of air pollution. It is mostly caused by heavy traffic. It is certain that if there are fewer people driving, there will be less air pollution.
The earth is our home. We must take care of it. That means keeping the land, water and air clean. And we must try to control the growth of population at the same time.

The human body is a living machine, and, like all machines, it needs “fuel” to supply it with energy. This is provided by the food we eat. But how much do we need to stay healthy?
The energy value of food is usually measured in calories(卡). A calorie is the amount of heat required to raise the temperature of 1 kg of water by 1℃. The number of calories people need per day is different, as the picture shows. Also, the number of calories you use at any one moment normally depends on the activity you are in. For example, you need more calories for standing than for sitting, more for running than for walking, and so on.
The energy in food is in the form of three kinds of chemical materials—carbohydrate(碳水化合物), protein(蛋白質(zhì)) and fat. Carbohydrate provides 3.8 Cal /gm of the energy, protein 4.0 Cal/gm, and fat 8.8 Cal/gm. Each food contains different amounts of these materials, as the round pictures show.
(P= protein      C= carbohydrate    F=fat)
小題1:How many calories are needed to raise the temperature of 5kg of water from 35℃ to 90℃?
A.55.B.175.C.325.D.275.
小題2:Which of the following contains the most amount of calories?
A.Milk.B.RiceC.Peanuts.D.Milk or peanuts.
小題3:Who needs the most amount of calories each day?
A.A woman.B.An office worker.C.A farmer.D.A boy aged 16.
小題4:Which of following is True?  
A.You need more calories for swimming than for mountain climbing.
B.A child aged 8 needs the same amount of calories every day as a man over 70 does.
C.A woman feeding baby needs over 4 times the amount of calories that a baby does.
D.Everyone needs the same amount of calories per day.
小題5:This passage mainly tells us ______.
A.a(chǎn)ll the energy is in food
B.the human body needs energy
C.the number of calories depends on your activity
D.we must only eat peanuts to get calories

Are some people born clever, and others born stupid? Or is intelligence (智力) developed by our environment and our experience? Strangely enough, the answer to these questions is yes. In some degree, our intelligence is given to us at birth, and no education can make a genius (天才) out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich environment. Therefore, the limits of person’s intelligence are fixed at birth, whether or not he reaches those limits will depend on his environment. This point of view, now is held by most experts.
It is easy to show that intelligence is something that we are born with. The closer the blood relationship between two people, the closer they are likely to be intelligence. If we take two strangers by chance from the population, it seems that their degree of intelligence will be completely different. If, on the other hand, we compare two twins, they will very likely be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depends on birth.
Imagine now that we take two twins and put them in different environments. We might send one, for example, to a university and the other to a factory separately where the work is boring. We would soon find differences in intelligence developing, and this shows that environment as well as birth plays an important role. This conclusion is also suggested by the fact that people who live in close contact (接觸) with each other, but who are not related at all are likely to have similar degree of intelligence.
小題1:How is man’s intelligence given?
A.At birthB.Through education
C.Both at birth and through educationD.Neither at birth nor through education
小題2:What does the underlined word mean in the first paragraph?
A.穩(wěn)固B.確定C.修理D.安排
小題3:According the passage, if a child is born with low intelligence, what might happen to him later?
A.Become a genius.
B.Still become a genius if he should be given special education.
C.Reach his intelligence limits in rich environment.
D.Never reach his intelligence in his life.
小題4:What can we learn from the example of the twins going to a university and to a factory?
A.The importance of their intelligence.
B.The role of environment on intelligence.
C.The importance of their jobs
D.The part that birth plays
小題5:What statement is TRUE according to the passage?
A.No education can help make a genius.
B.Personality is important as intelligence which was given to people at birth.
C.People who have similar degree of intelligence must be relatives.
D.Environment influences people in intelligence developing.

Different weather makes people feel different. It influences (影響) health, intelligence (智力) and feelings.
In August, it is very hot and wet in the southern part of the United States. People there have heart trouble and other kinds of health problems during this month. In the Northeast and the Middle West, it is very hot at some times and very cold at other times. People in these states have more heart trouble after the weather changes in February or March.
The weather can also influence intelligence. For example, in a 1983 report by scientists, IQ (智商) of a group students were very high when a very strong wind came, but after the strong wind, their IQ was 10% below. The wind can help people have more intelligence. Very hot weather, on the other hand (另一方面), can make it lower. Students in many schools of the United States often get worse on exams in the hot months of the year (July and August).
Weather also has a strong influence on people’s feelings. Winter may be a bad time for thin people. They usually feel cold during these months. They might feel unhappy during cold weather. But fat people may have a hard time in hot summer. At about 18C, people become stronger.
Low air pressure (氣壓) may make people forgetful. People leave more bags on buses and in shops on low-pressure days. There is a “good weather” for work and health. People feel best at a temperature of about 18 centigrade (攝氏度).
Are you feeling sad, tired, forgetful, or unhappy today? It may be the weather’s problem.
小題1:People may have more intelligence when _____ comes.
A.a(chǎn) rain B.very hot weather
C.a(chǎn) strong wind D.low air pressure
小題2:Low air pressure may make people _______.
A.forgetful B.sad C.a(chǎn)ngry D.tired
小題3:In “good weather” of 18 centigrade, _______.
A.people are very forgetful
B.people can’t do their work well
C.thin people feel cold
D.people are in better health
小題4:The writer wants to tell us that _______.
A.hot and cold weather influences all people in the same way
B.weather influences people’s lives
C.IQ never changes during weather changes
D.There is a good kind of weather for people’s work and health
