Scientists are trying to make the deserts into good land again. They want to bring water to the deserts， so people can live and grow food. They are learning a lot about the deserts. But more and more of the earth is becoming desert all the time. Scientists may not be able to change the desert in time.
Why is more and more land becoming desert？ Scientists think that people make deserts. People are doing bad things to the earth.

Without plants， the land can become desert more easily.

Everybody knows that words can carry messages. People communicate with words. Books, magazines, TV, radio and films all help us to communicate with others. They all help us to know what is going on in the world and what other people are thinking about.
Do you think you can communicate without words? A smile on your face shows you are happy or friendly. Tears in your eyes tell others that you are sad. When you put up your hand in class, the teacher knows you want to say something or ask a question. You shake your head, and people know you are saying “No”. You nod and people know you are saying “Yes”.
Other things can also carry messages. For example, a sign at the bus stop helps you to know which bus to take. A sign on the wall of your school helps you to find the library. Signs with arrows on doors tell you where to go in or out. Have you ever noticed that there are a lot of signs around you and that you receive messages from them all the time?

Are you a problem shopper? The answer is “Yes”, if you or someone else thinks that you sometimes get carried away with shopping. In other words, do you or does someone else think you are occupied in extreme shopping? If people have regrets later about their shopping, or have an “out-of-control” feeling about the quantities of what they buy or the amount of credit they use, they may be considered to be problem shoppers.
Extreme shopping can lead to a more serious problem — addictive shopping. Addictive shoppers feel driven by the desire to shop and spend money. They experience great tension which drives them to shop and spend money and they feel a “rush” during the time they are occupied with the shopping activity.
Extreme or addictive shopping may result from long-time unpleasant feelings, of which anxiety, pain and shame are common ones. When we feel bad inside, we often do something to make ourselves feel better. In this case, we often go shopping.
A few people shop to relieve their boredom or emptiness. For some people, the motivation is a desire for status, power, beauty or success. Some love to shop as it makes them feel valued in the eyes of the shop assistants. Others shop simply because it makes them forget, at least temporarily, tension, fear or unhappiness in their life.
Besides, shopping malls are designed to encourage continual shopping. For instance, there are some malls where you can’t see clocks displaying the time because they don’t want you to become too aware of the time you spend there.What’s more, food courts, coffee shops and restrooms are provided, so you don’t have to leave the mall because of your physical needs.
Therefore, once you become aware of how market forces work, you will certainly come to control your shopping behavior.For example, how much time you will spend and what areas you will visit can be decided before you enter the mall. Keep a written account of what items you will buy and how much money you will spend. Make a plan for what you are going to buy before you feel the urge to shop and then stick to it. That is vital for gaining self-control. Which of the following people may not be problem shoppers?
| A．Those who cannot control the amount of credit they use. |
| B．Those who just walk around the shopping malls. |
| C．Those who are occupied in too much shopping. |
| D．Those who feel sorry for their shopping. |
According to the passage, what may not result in addictive shopping?
| A．The awareness of how market forces work. |
| B．The desire for status, power, beauty or success. |
| C．Boredom, emptiness, tension, fear or unhappiness in people’s life. |
| D．Long-time bad feelings of anxiety, pain and shame. |
What does the author suggest to control our shopping behaviour?
| A．Never going to the shopping malls because there are many tricks. |
| B．Applying for a credit card before we go shopping. |
| C．Making the shopping time as short as possible. |
| D．Making a shopping list before we go shopping. |

Are you nervous about climbing because you think it’s too dangerous? Do you feel you’re not fit enough to climb? Do you know how to start climbing?
Let’s consider the idea that climbing is dangerous. Being afraid is natural, but if you use suitable ropes and other climbing equipments you will feel completely safe. Climbers are usually very careful because they know what they are doing is dangerous. Accidents happen, but when they do, they tend to attract a lot of publicity. As a result, people think there are many more accidents than there are in reality.
You cannot expect to start climbing straight away. Climbing is a challenge and challenges take time. It is necessary first of all that you achieve a good level of fitness. Begin as soon as you become interested in climbing—go to the gym, go swimming, take up jogging and continue to do so throughout your training period.
Discover as much as you can about climbing. Visit the library and find books especially for beginners or buy climbing magazines and look for articles which describe your situation. Look up information on the Internet. Find out about equipment, methods and places to go.
Next, take a course on a climbing wall. There are plenty of climbing walls all over the country which have trained and qualified people as instructors. Call your local leisure centre to find out if there is one in your area. These training sessions are a quick way to get experience and you are likely to meet other beginners. After this, you can do an outside course or join a club where you can meet climbers of all abilities and eventually join in group-climbing events.
At first you may not understand the importance of a good training period, but after you have completed your first climb and you are standing safely at the top of a rock feeling thrilled, then you will know it was the right thing to do.The article is written by ______.
| A．a doctor | B．an experienced climber |

In February 2006, Lydia Angyiou and her two sons were walking through their village in northern Canada. The sound of children shouting made her turn around. To her horror, Lydia saw a 700-pound polar bear behind her eyeing her seven-year-old son. Getting between the bear and her child, Lydia yelled at the children to run away. She then began hitting and kicking the animal as hard as she could. A neighbor who heard all the noise came and shot the bear. But everyone agreed it was Lydia who had saved her children’s lives. A local policeman described it this way: “… I guess when your back is up against the wall, … we come up with super-human strength.”
Where does this “super-human strength”, courage and quick thinking come from? Experts say it comes from stress! In stressful situations, the body releases chemicals that prepare it to take action. These chemicals give people the speed and strength they need to fight danger or run away from it.
When we think of stress, we usually think of its negative effects. Studies, though, show that moderate levels of stress are actually helpful. In fact, the way we perform is usually affected by the amount of stress we feel.
Stress causes the brain to release adrenaline(肾上腺素) which in turn increases our energy and excitement. The chemical gives us clearer minds and helps us to do more. This is why some people say they work better under a deadline.
Adrenaline that is not released for long periods of time can cause us to increase and strengthen our abilities instead of weakening them. We sometimes turn out our very best work when we push ourselves to the limit. Stress can also make us more confident. Handling small amounts of stress now prepares us for handling serious situations in the future. Who knows? Today’s stress may even prepare for the next polar bear that comes along!In the first paragraph, the case of Lydia Angyiou is mentioned to______.
| A．introduce the topic to be followed |
| B．remind us of the unexpected danger of life |
| C．praise Lydia Angyiou for her bravery |
| D．show the importance of super-human strength |
What does the policeman probably mean by saying “your back is up against the wall”?
| A．You are helped. | B．You are inspired. |
| C． You are confident. | D．You are cornered. |
What would be the best title for the passage?
| A．Brave Mother | B．The Cause of Stress |
| C．The Benefit of Stress | D．Super-human Strength |
