I can’t remember when I started collecting litter(垃圾). But it was when I got tired of seeing litter near my home and realized that no one else was going to pick it up.
I live close to a forest in Ohio, America. I can walk there in three minutes! I used to love going there to play with my dog. But one day there was so much litter there that I became very unhappy. I decided to clean up the forest. I wanted to feel happy going there again.
I made my first trip to clean the forest that afternoon. I took a big black rubbish bag with me. Ten minutes after starting to pick up litter, my bag was full! It had cans, bottles, broken glass and newspapers in it.
Since that first trip three years ago, I’ve gone to the forest four times a year to pick up litter. I’m often there for three hours. It makes me feel great to do something for the environment.
After each trip, I look at all the litter I’ve found. If any of it is recyclable(可回收的), I keep it. I can’t understand why people drop litter. But I will keep picking it up until they stop dropping it.
I know I can only do a small bit to help the earth, but I still think it is important.

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) 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?

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.

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.

American Classroom Rules
1. If the teacher asks a question, you should give an answer. If you do not understand the question, you should put up your hand and ask the teacher to repeat the question. If you don’t know the answer, it’s all right to tell the teacher that you don’t know. Then he or she knows what you need to learn.
2. There is no excuse for not doing your homework. If you can not go to school, you should call your teacher or your classmate and ask for the homework. It is your responsibility(責任)to find out what homework you have missed. It is not the teacher’s job to remind you of missed homework.
3. You must not be absent(缺席) on a test day. If you are badly ill, call and let the teacher know you will not be there for the test. If your teacher allows you to take a makeup, you should take the test within one or two days after you return to class. Bad illness is the only reason for missing a test.
4. Be on time! It’s not polite to be late. Also, it bothers other students. If you must come in late, be sure to do it quietly. Have your books out of your bag before you come into the classroom.

The robots were moving on a surface where they could slide(滑行). A team from California won the competition.
A second competition involved building a robot that could travel on uneven(不平坦的) surfaces, move objects with unusual shapes and withstand(承受) physical stress.
Another competition was for younger students, aged nine to fourteen years old. Eighty-four teams from twenty-seven countries competed with robots made with LEGO products. They had to design, build and program robots to explore the Earth’s climates.
