Only humans speak using words. But all kinds ...

Only humans speak using words. But all kinds in the animal world can communicate in one way or another. Maybe you have heard about the way bees dance around to send messages to each other and the way dogs bark in different ways to give warnings, to be friendly or to be playful. But did you know about infrasonic communication used by elephants? This is how it works:

Humans hear low sounds like thunder rumbling in the sky. But we don’t hear sounds lower than this. However, animals such as elephants and hippos can hear much lower sounds than humans can. And what’s more, they can make those low sounds as well, and they use them to communicate with each other. This is known as infrasound.

The amazing thing about infrasound is that it travels over several kilometers. Higher-level sounds like the one people can hear, don’t travel well through walls, leaves, trees and so on, which is why we can’t hear sounds from more than 100 meters away. But infrasound is much stronger and things like grass and trees have no influence on it. Therefore, it can travel much further. Elephants can hear infrasonic calls from four kilometers away!

There have been reports of people watching groups of elephants feeding or resting and then the elephants suddenly all stopped what they were doing for no reason at all. They obviously heard a warning call from a long way away, but the people didn’t hear a sound. In places like a zoo or wildlife park where you can get nearer to animals, it is a bit easier to sense when infrasonic sounds are made. When you stand near mother elephants with their babies in a zoo, you may notice a slight rumbling in the air every few minutes—not loud or strong, but clearly noticed. This is infrasonic communication—the mother elephants “talking” to their babies.

1.Why does the writer mention bees and dogs in Paragraph1?

A. Because they use infrasonic communication.

B. Because they communicate like the elephants.

C. Because they are examples of animal communication.

D. Because people want to learn how they communicate.

A. Humans can hear infrasound easily.

B. It travels nearly several kilometers.

C. It sounds low but can’t travel very far.

D. It travels well through walls, leaves and so on.

3.In places like zoos, ________.

A. elephants don’t need to make infrasonic sounds

B. it is easier for elephants to make infrasonic sounds

C. mother elephants don’t let people stand near their babies

D. humans can easily sense infrasonic sounds when they are made

4.Which would be the best title for the passage?

A. Talking to humans　　 B. Talking to animals

C. Playing with humans　　 D. Playing with elephants

A person has two ears but only one mouth. That means we should listen, not just speak. The word "listen" has the same letters as the word "silent". Listening silently is a good quality that we should have. Then why is it important to be a good listener?

Listening is really helpful.

When someone is sad or angry, he wants to express his poor feelings. At this moment, we need to listen silently first until he gets calm (冷静的). Then we may have a good talk with him. Maybe it is a good way to help him out.

Listening is a kind of love.

For example, we may think our parents are always talking too much. But in fact, they do so because they are anxious about our health, study and so on. If we listen patiently, our parents will feel we care about them. A loving silence is often more powerful (有力量的) than words.

Listening is polite behavior.

Sometimes, we just want others to listen to us but forget to listen to others. In fact, that's not polite. In order to show our respect(尊重) for others, we had better listen to them first. Then we can express our ideas.

Listening sounds easy， but it's not. Every head is a world. So we should learn to listen with our ears, eyes and hearts as much as we can, and try to make ourselves good listeners from now on.

1.When someone is sad or angry, we should _____ first.

A. listen to him silently

B. express our poor feelings

C. talk too much with him

Humans are social animals. They live in groups all over the world. As these groups of people live apart from other groups, over the years and centuries they develop their own habits and ideas, which form different cultures. One important particular side of every culture is how its people deal with time.

Time is not very important in non industrial societies. The Nuer people of East Africa, for example, do not even have a word TIME that is in agreement with the abstract thing we call time. The daily lives of the people of such non industrial societies are likely to be patterned around their physical needs and natural events rather than around a time schedule (时间表) based on the clock. They cook and eat when they are hungry and sleep when the sun goes down. They plant crops during the growing seasons and harvest them when the crops are ripe. They measure time not by a clock or calendar(日历), but by saying that an event takes place before or after some other event. Frequently such a society measures day in terms of “sleeps” or longer periods in terms of “moons”. Some cultures, such as the Eakinos of Greenland measure seasons according to the migration of certain animals.

Some cultures which do not have a written language or keep written records have developed interesting ways of “telling time”. For example, when several Australian aborigines want to plan an event for a future time, one of them places a stone on a cliff or in a tree. Each day the angle of the sun changes slightly. In a few days, the rays of the sun strike the stone in a certain way. When this happens, the people see that the agreed - upon time has arrived and the event can take place.

In contrast (成对比), exactly correct measurement of time is very important in modern, in detribalized societies. This is because industrialized societies require the helpful efforts of many people in order to work. For a factory to work efficiently (well, quickly and without waste), for example , all of the workers must work at the same time, Therefore, they must know what time to start work in the morning and what time they may go home in the afternoon. Passengers must know the exact time that an airplane will arrive or depart. Students and teachers need to know when a class starts and ends. Stores must open on time in order to serve their customers. Complicated (复杂的) societies need clocks and calendars. Thus, we can see that if each person worked according to his or her own schedule, a complicated society could hardly work at all.

1.By saying “Humans are social animals”, the author means ________.

A.they live all over the world.

B.they are different from other animals

C.they live in one area as a whole

D.they are divided into many groups

2.Time is not very important in non industrial societies. This is because people in those societies ________.

A.don’t have the word TIME in their languages

B.don’t get used to using clocks and other timepieces

C.don’t measure time in their daily lives

D.don’t need to plan their daily lives around an exact time schedule

3.The Australian aborigines’ way of “telling time” is based on ________.

A.the change of the sun rays

B.the movement of the earth in relation to the sun

C.the position of the stone

D.the position of the tree or the cliff

4.Which of the following night be the best title for this passage?

A.Time and Culture

B.The Measurement of Time

C.Time schedule and Daily Life

D.Clock, Calendar and Society

九年级英语单选题简单题查看答案及解析

Humans are land animals, but we are also closely connected to the sea. In history, the sea has given a lot to mankind. The sea has provided man with food and a better way to travel to different parts of the world.

In the modern world, the sea offers many resources to help mankind survive. Resources on land are going to meet the end. The sea, however, still can be hoped to satisfy man's needs.

The list of riches of the sea to be developed by man's technology is amazing. Oil and gas explorations have been carried out for nearly 30 years. Valuable minerals on the ocean floor are ready to be mined(开采).

Fish farming promises to be a good way to produce plenty of food. The culture of fish and shellfish is an ancient skill practiced in the past mainly by eastern people.

Besides oil and gas, the sea may offer new sources of energy. Experts believe that the warm temperature of the ocean can be used in a way similar to the steam(蒸汽) in a steamship. Ocean waves offer possible use as a source of energy.

Technology allows man to explore more deeply under the sea. The development of strong, new materials has made this possible.

The technology to harvest the sea continues to improve. Scientists believe that by the year 2050 the problems that prevent us from making full use of the food, minerals, and energy sources of the sea will be largely solved.

1.According to the passage, which is not in the list of the riches of the sea?

A. Ocean winds B. Minerals C. Fishes and shellfishes D. Oil and gas

2.When will the problems to explore the deeper sea largely possibly be solved?

A. In the next century. B. At the end of the 20th century.

C. By the middle of the 21st century. D. In a couple of years.

3.Why does the writer mention a steamship in paragraph 5?

A. To show that a steamship is better than other kinds of ships.

B. To explain that man can make use of sources of energy from the sea.

C. To argue that man should use steamships.

D. To describe that it is warmer in the ocean than on land.

4.What is the best title for the passage?

A. Needs of Man. B. Sea and Sources of Energy.

C. Sea Exploring Technology. D. Sea Harvest and Food.

5.We can conclude(得出结论) from the passage that ______.

A. harvesting rice in the sea will be made possible
