Some time people call each other “scared-cat”,but have you ever thought about this expression? When a cat is frightened,its heart starts beating faster,its muscles get tense,and there are changes in the chemicals in its bloodstream.Although the cat doesn't realize this,its body is getting ready for action.If the danger continues,the animal will do one of two things:It will defend itself,or it will run away as fast as it can.

Something like this also happens to people.When we are excited,angry,scared,or aroused by other emotions (feelings),our bodied go through many physical changes.Out hearts beat faster,and our muscled get tense.All of these changes make us more alert and ready to react.We,too get ready to defend ourselves or run.

Human beings,however,have a problem that animals never face.If we give way to our feelings and let them take over,we can get into trouble.Have you ever said something in anger—or hit somebody—and regretted it later? Have you ever shouted at a teacher,told somebody you were lonely,or said you were in love,and then wished later you had kept your mouth shut? It isn't always wise to express your feelings freely.

Does this mean that it's smarter always to hide our feelings? No! If you keep feelings of anger,sadness,and bitterness hidden away or bottled up inside,your body stays tense.Physical illness can develop,and you can feel churned up inside.It can actually be bad for your health.(It isn't good to keep pleasant feelings inside either;all feelings need to be expressed.)

Feelings that you keep all bottled up inside don't just go away.It's as if you bought some bananas and stuck them in a cupboard.You might not be able to see them,but before long you'd smell them.And if you opened the cupboard,chances are you'd see little fruit flies hovering all over them.They'd be rotten.

You can try to treat emotions as if they were bananas in the cupboard.You can hide them and you can pretend they don't exist,but they'll still be around.And at last you'll have to deal with them,just like those bananas.

Early people had very little effect on the environment. They lived in caves in very small “clan” groups. They collected or killed only enough for the clan’s survival. Early clans were nomadic, which mean that they didn’t stay in one place. Instead, they moved around, following the animals that were their main food source and seeking areas where seasonal plants grew wild. Moving around seasonally helped to protect the environment. The land had time to recover and animals had time to breed (繁殖)before the clan returned for the next season..

As time went by, these small family clans joined with others to form larger groups for protection. Joining with other clans gave them more hunters and more women to help cut up the meat and share it between families. Eventually, people tamed(驯养)wild animals such as dogs and horses. People settled around rivers and fertile plains to share responsibilities and duties. Then, people began to plant crops instead of moving to areas where the plants grew. This development changed the environment.

Traditional forms of work also changed. Some people were better at performing a particular task than other clan members, so then began to specialize in things they were good at doing. This also meant that they began to exchange their goods for things that others produced.

People began to communicate with distant tribes. Land was cleared for roads. Foreign plants and animals were transported to places where they had not existed before. Specialization also give people more free time. So art ,dance and music became important ways of expressing feelings and thoughts. This was how many great civilizations started.

Compared to the past, modern civilization has experienced many changes to become the highly developed society that exists today. Populations have increased rapidly. Forests have been cleared for farms. Inventions and technology have made work easier.

However, pollution and other serious problems have also resulted from human progress. As concerned citizens, it is up to us to learn from past mistakes and to help maintain and improve our environment.

A .they kept animals for themselves B they ate only vegetables

C they loved animals D they killed only enough for food

The main purpose for small clans to join together was_____

A to hurt animals B to seek safety

C to share caves D to protect environment

According to the passage ,we can learn that_____

A early people moved to new places looking for new sources of food

B modern civilization began when people started to live together in big groups

C modern advancements are always good for the environment

D people began to exchange goods because they didn’t have enough money

It can be concluded from the passage that_____

A human progress has brought civilization to the society

B civilization has improved traditional forms of work

C early people understood environmental protection

D our environment has been affected by human progress

Emotions Affect Our Bodies

Sometimes people call each other“scaredy-cat”, but have you ever thought about this expression?When a cat is frightened, its heart starts beating faster, its muscles get tense, and there are changes in the chemicals in its blood stream.

Although the cat doesn’t realize this, its body is getting ready for action.

If the danger continues, this animal will do one of the two things. It will defend itself or it will run away as fast as it can.

Something like this also happens to people. When we are excited, angry, scared, or aroused by other emotions, our bodies go through many physical changes. Our hearts beat faster, and our muscles get tense. All of these changes make us more alert and ready to react. We, too, get ready to defend ourselves or run.

Human beings, however, have a problem that animals never face. If we give way to our feelings and let them take over, we can get into trouble. Have you ever said something in anger—or hit somebody—and regretted it later? Have you ever shouted at a teacher, told somebody you were lonely or said you were in love, and then wished later you had kept your mouth shut? It isn’t always wise to express your feelings freely.

Does this mean that it’s smarter always to hide our feelings? No! If you keep feelings of anger, sadness and bitterness hidden away or bottled up inside, your body stays tense. Physical illness can develop, and you can feel churned up inside. It can actually be bad for your health.

Feelings that you keep all bottled up inside don’t just go away. It’s as if you bought some bananas and stuck them in a cupboard. You might not be able to see them, but before long you’d smell them. And if you opened the cupboard, chances are that you’d see little fruit flies hovering all over them. They’d be rotten.

You can try to treat emotions as if they were bananas in the cupboard. You can hide them and you can pretend they don’t exist, but they’ll still be around. And at last you will have to deal with them, just like those bananas.

Most people around the world are right-handed. This also seems to be true in history. In 1799, scientists studied works of art made at different times from 1,500 B.C. to the 1950s. Most of the people shown in these works are right-handed, so the scientists guessed that right-handedness has always been common through history. Today, only about 10% to 15% of the world’s population is left-handed.
Why are there more right-handed people than left-handed ones? Scientists now know that a person’s two hands each have their own jobs. For most people, the hand is used to find things or hold things. The right hand is used to work with things. This is because of the different work of the two sides of the brain. The right side of the brain, which makes a person’s hands and eyes work together, controls the left hand. The left-side of the brain, which controls the right hand, is the centre for thinking and doing problems. These findings show that more artists should be left-handed, and studies have found that left-handedness is twice as common among artists as among people in other jobs.
No one really knows what makes a person become right-handed instead of left-handed. Scientists have found that almost 40% of the people become left-handed because their main brain is damaged when they are born. However, this doesn’t happen to everyone, so scientists guess there must be another reason why people become left-handed. One idea is that people usually get right-handed from their parents. If a person does not receive the gene(基因) for right-handedness, he / she may become either right-handed or left-handed according to the chance and the people they work or live with.
Though right-handedness is more common than left-handedness, people no longer think left-handed people are strange or unusual. A long time ago, left-handed children were made to use their right hands like other children, but today they don’t have to.

It’s really true what people say about English politeness: it’s everywhere. When squeezing (挤过去) past someone in a narrow passage, people say “sorry”. When getting off a bus, English passengers say “thank you” rather than the driver. In Germany, people would never dream of doing these things. After all, squeezing past others is sometimes unavoidable, and the bus driver is only doing his job. I used to think the same way, without questioning it, until I started traveling to the British Isles, and here are some more polite ways of interacting (交往) with people in UK.

People thank each other everywhere in England, all the time. When people buy something in a shop, customer and shop assistant in most cases thank each other twice or more. In Germany, it would be exceptional to hear more than one thank you in such a conversation. British students thank their lecturers when leaving the room. English employers thank their employees for doing their jobs, as opposite to Germans, who would normally think that paying their workers money is already enough.

Another thing I observed during my stay was that English people rarely criticize (批评) others. Even when I was working and mistakes were pointed out to me, my employers emphasized several times but none of their explanations were intended as criticism. It has been my impression that by avoiding criticism, English people are making an effort to make others feel comfortable. This also is showed in other ways. British men still open doors for women, and British men are more likely to treat women to a meal than German men. However, I do need to point out here that this applies to English men a bit more than it would to Scottish men! Yes, the latter are a bit tightfisted.

1.What is the author’s attitude towards English politeness?

A．He thinks it is unnecessary.	B．He thinks little of it.
C．He appreciates it very much.	D．He thinks it goes too far.

2.What can be inferred from the passage?

A．German men never treat a woman to dinner.

B．The author think it’s unnecessary to say “thank you” to the bus driver.

C．In Germany, employers often say “thank you” to employees for their job.

D．Germans think it is unnecessary to thank workers because payment is enough.

3.We can learn from the last paragraph that Scottish men ______.

A．like to fight with each other

B．treat women in a polite way

C．are as generous as English men

D．are unwilling to spend money for women

4.The author develops the text through the method of ______.

A．making comparisons	B．telling stories
C．giving reasons	D．giving examples
