Today we live in a world where GPS systems, digital maps, and other navigation apps are available on our smart phones. 1 of us just walk straight into the woods without a phone. But phones 2 on batteries, and batteries can die faster than we realize. 3 you get lost without a phone or a compass, and you 4 can’t find north, a few tricks to help you navigate 5 to civilization, one of which is to follow the land... When you find yourself well 6 a trail, but not in a completely 7 area, you have to answer two questions: Which 8 is downhill, in this particular area？ And where is the nearest water source？ Humans overwhelmingly live in valleys, and on supplies of fresh water. 9 , if you head downhill, and follow any H2O you find, you should 10 see signs of people. If you’ve explored the area before, keep an eye out for familiar sights—you may be 11 how quickly identifying a distinctive rock or tree can restore your bearings. Another 12 : Climb high and look for signs of human habitation. 13 , even in dense forest, you should be able to 14 gaps in the tree line due to roads, train tracks, and other paths people carve 15 the woods. Head toward these 16 to find a way out. At night, scan the horizon for 17 light sources, such as fires and streetlights, then walk toward the glow of light pollution. 18 , assuming you’re lost in an area humans tend to frequent, look for the 19 we leave on the landscape. Trail blazes, tire tracks, and other features can 20 you to civilization. 1.

第3题

Crime is a very serious problem in Britain. One sort of crime which particularly worri

es people is juvenile delinquency—that is, crimes committed by young people. For some years juvenile delinquency had been increasing. There are two main sorts of juvenile crimes: stealing and violence. Most people do not understand why young people commit these crimes. There are, I think, a large number of different reasons.

These crimes are not usually committed by people who are poor or in need. Young people often dislike and hate the adult world. They will do things to show that they are rebels. Also in Britain today it is easier for young people to commit crimes because they have more freedom to go where they like and more money to do what they like.

There are two other possible causes which are worth mentioning. More and more people in Britain live in large towns. In a large town no one knows who anyone else is or where they live. But in the village I come from crimes are rare because everyone knows everyone else.

Although it is difficult to explain, I think the last cause is very important. Perhaps there is something with our society which encourages violence and crime. It is a fact that all the time children are exposed to films and reports about crime and violence. Many people do not agree that this influences the young people, but I think that young people are very much influenced by the society they grow in. I feel that the fault may be as much with our whole society as with these young people.

6. From the passage we know that many British people are confused about ().

A. the cause of juvenile crimes

A. young people nowadays do not like adult world

B. young people in Britain today are freer than before

C. too many young people have come to live in big cities

D. young people are influenced by crime and violence in films and newspapers

第6题

Mobile phones are the items that a lot of people are having today. However，do we really

need to have a mobile phone by our side？

We could start with the advantages of mobile phones. There are many things that we could do with mobile phones. With the advancement of technology，more and more features are being added to the mobile phones which make them more useful. In addition to making calls，mobile phones also support a wide variety of other services such as text messaging，email，Internet access，business applications，gaming and photography. We can bring them everywhere，and can be reached by others anytime. They make the world smaller，bringing people together no matter where they are.

But we could have some risks when using our mobile phones. We may have accidents when we use them while driving. Some studies show that mobile phones can do harm to our bodies;and materials in mobile phones could damage our environment.

Since there are so many risks，why do we still have mobile phones？This is because these risks or disadvantages can be overcome. For example，while we are driving we can easily pull up our car if we really need to use the phone. Mobile phone manufacturers are reducing the radiation of mobile phones to avoid health risks.

Though there are both pros and cons of using mobile phones，we could easily see that there are more advantages than disadvantages. Moreover，mobile phones are becoming cheaper，which might be another reason why mobile phones are increasingly used today.

1. Which of the following functions is NOT mentioned in the passage？

A. Text messaging.

B. Camera.

C. GPS.

2. What risks might mobile phones cause？

A. Traffic accidents and health problems.

B. Environmental damage.

C. Both A and B.

3. What are mobile phone manufacturers doing to prevent mobile phone users from health risks？

A. They are reducing the radiation of mobile phones.

B. They are trying to persuade people to use mobile phones less.

C. They are developing new models of mobile phones.

4. Why do people still use mobile phones despite their disadvantages？

A. Because people don’t believe that mobile phones have any disadvantages.

B. Because the disadvantages of mobile phones can be avoided.

C. Because people cannot live without mobile phones.

5. According to the last paragraph，why are mobile phones increasingly being used today？

A. They are safer.

B. They have more functions.

C. They are becoming cheaper.

第8题

Have you wished for a magic pill or magic formula that would let you live happily fore

ver？ If you have, don’t feel alone! It’s a very common, natural wish that has a long history.Spanish explorers of the sixteenth century even tried to find a fountain of youth in what is now the state of Florida.The water the this legendary fountain, which no one has yet found, was believed to restore youth and good health to those who drank it.

Biologists today don’t expect that anyone will find a magical fountain of youth.Growing older is a natural part of the life cycle that can’t be reversed.As human beings grow older, organs such as the heart and lungs may stop functioning properly.Sight and hearing may become weak.And the human body becomes more likely to come down with serious illnesses from which it cannot recover.

Considered together, changes that bring about the decline of an organism are called aging.Because of aging, many biologists believe that there may be a maximum age limit to which even the healthiest organisms can live.For human beings, this maximum age limit is about 110 years.

Perhaps the most important thing that you can learn from your study of human biology is that you have a lot of control over the aging process in your own life.In fact, within our control are many physical and mental factors that have much to do with aging.For example, each of us, as recent research indicates, can do many things to help prevent heart and vessel disease, which causes half the death each year in the United States.We can avoid eating a lot of fatty meat.Eating too much of these types of animal fats can lead to the clogging and hardening of blood vessels.We can cut back on smoking and hopefully quit entirely.We can limit the amount of alcohol we drink and the amount of sugar we eat.We can exercise regularly and strengthen the heart and other organs.And we can remember to take time out each day for ourselves, time just relax.Exercise, recreation and relaxation all reduce stress – inner tension that is hard on all body organs.

One final thing we can do is to try to keep aware of advances made in health education.Information is often available free of charge from health clinics or schools.

1.Which of the following is the leading cause of death in the United States？

A.Heart disease.

B.Cancer

C.Alcohol

D.Smoking

2.What happens as people grow older？

A.They dream of a magic pill to help them live a happy and long life

B.They come down with serious illnesses

C.Their organs become weak and may stop working properly

D.Their blood vessels become clogged

3.In the opinion of biologists, _________.

A.the aging process can be reversed

B.the aging process can be controlled and slowed down

C.the aging process can be got rid of

D.the aging process can go beyond its limit

4.We can slow down the weakening of all our body organs by ______.

A.not eating animal fat

B.limiting drinking and smoking

C.exercise, recreation and relaxation to reduce stress

D.preventing the clogging and hardening of blood vessels

5.Besides physical and mental factors, which of the following also contributes to living a long and healthy life according tot the passage？

A.Health education

B.Traditional medicine

C.artificial organs

D.The invention of magic pills
