All living things on the earth need other living things to live. Nothing lives alone. Most animals must live in a group, and even a plant grows close together with others of the same kind. Sometimes one living thing kills another, one eats and the other is eaten. Each kind of life eats another kind of life in order to live, and together they create a food chain (链条). Some food chains are simple, while others are not. But all food chains begin with the sun, and all food chains become broken up if one of the links (链接) disappears.

All life needs sunlight to live on. But only plants can use sunlight directly. Plants are ‘factories’. They make food from sunlight, water and things in the soil (土壤) and air. Plants feed all other living things. Animals can only use the sun’s energy after it has been changed into food by plants. Some animals feed directly on plants, others eat smaller animals. Meat-eating animals are only eating plants indirectly.

What about humans? We are members of many food chains. We eat rice, vegetables, and fruits and so on. We also eat meat and drink milk. But we often break up the food chains. We kill wild animals and also make rivers, lakes and seas polluted. When these rivers, lakes and seas are polluted, the fish in them can not be eaten. If we eat the fish, we will get strange illnesses.

Each form of life is linked (关联的) to all others. Breaking the links puts all life in danger.

1.Which living things can use the sun’s energy directly?

2.Who often destroy the food chains?

3.Which of the following would be the best title for this passage?

All our food comes from the soil(土壤). Some of us eat meat, but animals live on plants. If there are no plants, we will have no animals and meat. So the soil is necessary for us to live.

The top of ground is usually covered with grass or other plants. Plants grow in soil, which has a dark color. This dark soil is humus. Dead leaves, dead plants and animals’ waste make it, but this takes a long time. When the humus has been made, plants can grow well in it.

All soil needs food. If we don’t give it any, the plants will be weak. 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 is better to have a different crop. A change of crop and the use of a good fertilizer will keep the land in good condition.

When the soil is dry, the wind blows it away. Sometimes heavy rain carries the humus down to a river. People should grow more and more trees and grass to stop wind from carrying the humus (腐殖土壤)away. It takes hundreds of years to make humus, and so we must save every bit of it. Without soil, where can we grow food?

1. From the text, we know people live on ___________.

A. animal B. plant

C. meat　　　 D. soil

2. We should ___________ to keep the soil.

A. give more fertilizers

B. grow a different crop every year

C. make more humus

D. grow more trees and grass

3. We should save every bit of humus, because ___________.

A. it takes a long time to make humus

B. sometimes the wind will blow the dry soil away

C. the chemical fertilizers are expensive

D. animals waste is the best food for the soil

4.From the passage, we know that soil is ___________ to people.

A. not helpful　　　　 　　 B. necessary

Frogs are animals that can live both in water and on land. There are more than 5,000 kinds of frogs on the earth. The earliest known frogs lived about 190 million years ago and the frogs today still look the same. Here are some fun things that you might not know about frogs. Enjoy!

The Biggest and the Smallest Frogs

Some frogs can be very big. The biggest kind of frog is the Goliath Frog in West Africa. Its body can be nearly 30cm long, about the size of a large cat. The Gold Frog and the Poison Frog are the smallest frogs in the world. They are less than 1cm long. Though the Poison Frog is very small, it is not weak at all. It is dangerous. Any animal that eats it will die very soon.

The Best Jumpers

Frogs are very good at jumping. They developed jumping legs so that they would not be eaten by other large animals. Using their big strong legs, more frogs can jump over 20 times their own length. The Australian Rocket Frog can even jump over 2m, which is 50 times its body length (5.5 cm). That might be the reason why frogs are called the best jumpers on the earth.

The Cryogenic Animal

Some frogs like the Common Wood Frog have a special ability to live in very cold places. When the temperature goes down, they become ice frogs. 2/3of their body water freezes. Their hearts stop, and their breathing stops too. You may think they are dead, but in fact they are not. Maybe we humans can learn the way that the frogs do for medical purpose.

1.The earliest frogs lived about ________ million years ago.

A．20

B．30

C．50

D．190

2.________ can jump over 2m.

Computers can help us in many ways, but they cannot think or do things on their own. Humans have to feed them with information and tell them what　　 to do. They cannot come up with any new information, but they can save much time and work. For example, all the information and the office files (文件) can be stored in a computer’s “memory”.

The first computers were huge and expensive. They filled up almost the whole floor of large offices. Later, scientists found ways to produce cheaper and smaller computers. They invented chips (芯片) which made it possible to store more information in less space.

Today, computers are not only cheaper, but also more compact. They can just be placed on top of an ordinary writing table. They can even be carried from place to place easily. Computers are not only used in offices by companies, but are used at home by families who can afford them.

Robots are only moving parts controlled by computers. A robot can do the same work as a person for 24 hours without complaining or getting tired.

In Japan and some places in America, robots are used in factories to assemble (装配) cars. As computers become more and more common in businesses and factories, people fear that one day computers and computer-controlled robots will put human workers out of work.

1.What were the first computers like?

A.Small and cheap B.Huge and expensive C.Small and expensive D.Huge but cheap

2.The underlined phrase “more compact” can be replaced by “　　”.

A.larger B.brighter C.smaller D.heavier

3.Which of the following is NOT true according to the passage?

A.Robots are controlled by computers. B.Robots can do the same work as humans.

C.Robots do not get tired of working. D.Robots are used to sell cars in China.

4.Humans fear that one day computers and robots 　　.

A.will be busier than humans B.will be cleverer than humans

C.will make humans jobless D.will make humans become blind

5.The BEST title for this passage can be 　　.
