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 (接触) with each other, but who are not related at all are likely to have similar degree of intelligence.

A.At birth | B.Through education |

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 |
A.No education can help make a genius. |
B.Personality is important as intelligence which was given to people at birth. |

When do you think of a forest, what do you see? Just trees? Or do you see many other things, such as singing birds, colorful plants and wild flowers?
The forest is a whole world of its own. It is full of many different living things(生物). But even though they are all different, they have one thing in common: they all need each other in order to live on.
The trees feed the forest “people” by making food in their leaves; by using sunlight to join water and minerals(矿物) from the soil and air. Their deep network of roots joins the soil together and stops it from dying out, making it possible for living things to live in it.
Human beings(人类) are like the living things in the forest. We need one another in order to live. We need the farmers to grow our food, railroad and truck drivers to bring it to our shops and clerks(售货员) to sell it to us. We need people to prepare our food and cook it and others to take our waste things away. Then, of course, we need doctors, nurses, government leaders, mailmen, telephone operators, and many others.
We also need other human beings in another way. We need people for friendship, to talk over our problems, exchange ideas. Think how lonely and unhappy you would be if you lived all alone.
Life is a matter of giving and taking. We need to help other people as much as we need other people to help us. Think what a good feeling you have when you have done something for someone else!
小题1:According to the text, colorful plants and flowers live on _____.
A.the leaves of the trees | B.water and minerals |
C.the soil and air | D.all of the above |
A.trees | B.birds | C.plants | D.farmers |
A.different from | B.like | C.dislike | D.unhappy with |
A.we need people for friendship |
B.we need one another in order to live |
C.the forest is a whole world of its own |
D.the forest is full of different living things |
A.We can see trees in the forests. |
B.We like the living things in the forest. |
C.We need farmers to grow our food in the forest. |
D.We are the same as the forest; We need each other to live on. |
What will the house look like in the future? Could it have gardens on its walls, or a pool with fish for dinner? Architects(建筑师) believe that they are all possible. The only thing for sure is that the houses will be as green as possible.
The tree house
Many architects in the world would like to build a “tree house.” Like a leaf, the surface of the house collects sunlight during the day. The energy can be used to heat water, produce electricity, and even create fresh air for the home. The “root” (根) of the house is deep under the ground. It uses the soil (土壤) to keep the home’s temperature.
The Lizard house
Like a lizard (蜥蜴), changing color with the weather is the most important design of a lizard house. When it’s in the bright sun, the cover of the house will turn dark to protect it from strong heat. During dark days, it turns white and takes in as much light and heat as possible to produce energy.
Meals at home
This design is perhaps as much about the future of food production as architecture (建筑风格). It has gardens on the outside wall of the house. People can plant tomatoes, carrots and green tea on them. So every day in the morning, you just need to walk outside and collect your meals.
Learning from the past
Looking to the future isn’t the only way to be green. Sometimes, ancient techniques (古老的技术) can also help cut down energy use. For example, a chimney (烟囱) can be a useful air conditioner because it is easier to flow out hot air from the chimney.
小题1:What is the best title (标题) of the passage?
A.Green house of the future | B.The greener, the better |
C.How to build green houses | D.Changes of the houses |
A.with the root of a leaf | B.with the energy from sunlight |
C.with the soil under the ground | D.with gardens on its walls |
A.It will take in light. | B.It will produce energy. |
C.It will turn dark. | D.It will turn white. |
A.will be more delicious | B.need more cooks |
C.cost as much as possible | D.will be greener |
A.pollution | B.accident | C.noise | D.techniques |
Do you get angry when your friends sing loudly? Or when your best friend does not wait for you after school?
If you do, you need to control(控制) your feelings and stop getting angry so easily. Getting angry easily can make you lose friends.
Gary Egeberg, an American high school teacher, wrote My Feelings are Just Like Wild Animals to help you control your feelings. It tells teens how to stay cool when bad things happen to them. The book says that getting angry only makes problems worse. It can not make them better. “Getting angry is not a natural way to act”, the book says. It is just a bad habit, like smoking. The book says you can control your anger easily, and all you have to do is to tell yourself not to be angry.
When a baby falls over, it cries only when people are watching it. Like a baby, you can only get angry if you are sure it is the right thing to do.
The book gives many suggestions to help you if you get angry easily. Here are the top three.
①Keep a record. Every time you get angry, write down why you are angry. Look at it later and you will see you get angry too easily.
②Ask your friends to stop talking to you when you get angry. This will teach you not to be angry.
③Do something different. When you get angry, walk away from the problem and go somewhere else. Try to laugh!
小题1:The writer wants to tell us ____.
A.not to get angry easily | B.to work hard at school |
C.to do more exercises | D.to help each other |
A.get ill very easily | B.lose your friends |
C.put on weight easily | D.eat less |
A.story | B.book | C.picture | D.film |
A.what to read | B.how to read |
C.how to stay cool | D.how to learn English well |
A.the book | B.anger | C.habit | D.the baby |
All soil needs food. If we do not give it any, the plants will be weak. Farmers found that animals’ waste is the best food for the soil, but chemical fertilizers(化肥)are also very useful. The same crop(庄稼)should not be grown in the same place every year, it’s better to have a different crop. A change of crop and the use of a good fertilizer will keep the land good.
小题1:Which of the following is true?
A.All our food comes from the soil. |
B.Most of our food comes from soil. |
C.None of our food comes from the soil. |
D.All our food comes from animals. |
A.Leaves, plants, grass and waste live on each other. |
B.There would be no animals without meat. |
C.There would be no plants without animals. |
D.People, animals, plants and soil live on each other |
A.Chemical fertilizers. | B.Plants and grass. |
C.Animals’ waste. | D.Different crops. |
A.Because we can keep the soil rich this way. |
B.Because we don’t have enough land. |
C.Because we want to have a different food. |
D.Because we do this as a habit(习惯). |
