The production of coffee beans is a huge, profitable business, but, unfortunately, full-sun production is taking over the industry and bringing about a lot of damage. The change in how coffee is grown from shade-grown production to full-sun production endangers the very existence of, certain animals and birds, and even disturbs the world’s ecological balance.
On a local level, the damage of the forest required by full-sun fields affects the area’s birds and animals. The shade of the forest trees provides a home for birds and other special(物种) that depend on the trees’ flowers and fruits. Full-sun coffee growers destroy this forest home. As a result, many special are quickly dying out.
On a more global level, the destruction of the rainforest for full-sun coffee fields also threatens(威胁)human life. Medical research often makes use of the forests' plant and animal life, and the destruction of such species could prevent researchers from finding cures for certain diseases. In addition, new coffee-growing techniques are poisoning the water locally, and eventually the world's groundwater.
Both locally and globally, the continued spread of full-sun coffee plantations (种植园)could mean the destruction of the rainforest ecology. The loss of shade trees is already causing a slight change in the world's climate, and studies show that loss of oxygen-giving trees also leads to air pollution and global warming. Moreover, the new growing techniques are contributing to acidic(酸性的) soil conditions.
It is obvious that the way much coffee is grown affects many aspects many aspects of life, from the local environment to the global ecology. But consumers do have a choice. They can purchase shade-grown coffee whenever possible, although at a higher cost. The future health of the planet and mankind is surely worth more than an inexpensive cup of coffee.What can we learn about full-sun coffee production from Paragraph 4?
| A．It limits the spread of new growing techniques. |
| B．It leads to air pollution and global warming. |
| C．It slows down the loss of shade trees. |
| D．It improves local soil conditions. |

When I first entered high school, I knew no one at my school. All my friends in middle school went to other schools. I wanted to make some new friends. However, I was shy and wasn’t good at making new friends. On my first day at school, I looked at others who were talking in groups happily. How I wish I were one of them!
I guess I was very lucky then. At lunch in the dinning hall, when I was eating at a table alone, a girl came to me. “Excuse me, is this seat taken?” she asked. I immediately shook my head. She smiled and sat down opposite(面对) to me. I felt a little awkward and didn’t know what to say at all, but I really wanted to communicate with her. It was a good opportunity to make friends with her. When I looked up, I found she was smiling at me. Her smile calmed me down. “I really like this school. It’s beautiful, but I don’t know anyone here. All my friends went to other schools,” said the girl. Hearing her words, I immediately said, “my friends are not here either. Can we be friends?” I was surprised. I couldn’t believe I would say something like that, and to my surprise, that girl immediately said “yes”. We both smiled.
We became very good friends. Now it’s the beginning of a new term again. Many students may have no friends at their new schools.

Throughout the world, clothing has many uses. It is used to provide protection from cold. It is also worn to prevent others from seeing specific parts of one’s body. However, the parts of the body that must be covered vary widely throughout the world. Some clothing is worn to provide supernatural protection. Wearing a lucky shirt to take an exam is calling for supernatural assistance.
People in all cultures use clothing and other forms of bodily decoration to communicate status(身份), intentions and other messages. In North America, we dress differently for business and various leisure activities. North American women usually are much more knowledgeable of little difference in messages communicated by clothes than men. At times, this leads to silly mistakes of understanding of female intentions on the part of men. Of course, clothing styles also are intended to communicate messages to members of the same gender（性别）.
Long before we are near enough to talk to someone, their appearance tells their gender, age, economic class, and often even intentions. We begin to recognize the important cultural clues at an early age. The vocabulary of dress that we learn includes not only items of clothing but also hairstyles, jewelry, and other body decoration. In most cultures, however, the same style of dress communicates different messages depending on the age, gender, and physical appearance of the individual wearing it.
Putting on certain types of clothing can change your behavior and the behavior of others towards you. This can be the case with a doctor’s white lab coat, or an army uniform. Most uniforms are clearly symbolic so that they can rapidly and unmistakably communicate status. For instance, the strange hairstyle and clothing of the English “punks” are essential aspects of their uniforms.
There are many forms of body decoration other than clothes that are used around the world to send messages. These include body and hair paint, and even body deformation. When doctors put braces on teeth, they are actually doing the same thing – deforming or reforming a part of the body to make it more attractive.Which of the following is the best title for this passage?

Most young people enjoy some forms of physical activities. It may be walking, cycling or swimming, or in winter, skating or skiing. It may be a game of some kind, football, hockey, golf, or tennis, it may be mountaineering.
Those who have a passion for climbing high and difficult mountains are often looked upon with astonishment. Why are men and women willing to suffer cold and hardship, and to take risks on high mountaineering? This astonishment is caused probably by the difference between mountaineering and other forms of activity to which men give their leisure.
Mountaineering is a sport and not a game. There are no manmade rules, as there are for such game as golf and football. There are, of course, rules of a different kind, which would be dangerous to ignore, but it is this freedom from manmade rules that makes mountaineering attractive to many people. Those who climb mountains are free to use their own methods.
If we compare mountaineering with other more familiar sports, we might think that one big difference is that mountaineering is not a “game”. We would be mistaken in this assumption. There are, it is true, no “matches” between “teams” of climbers, but when climbers are on a rock face linked by a rope on which their lives may depend, there is obviously teamwork.
The mountain climber knows that he may have to fight forces that are stronger and more powerful than man. He has to fight the forces of nature. His sport requires high mental and physical capacities.
A mountain climber continues to improve in skill year after year. A skier is probably past his prime by the age of thirty, and most international tennis champions are in their early twenties. But it is not unusual for a man of fifty or sixty to climb the highest mountains in the Alps. They may take more time than younger men, but they probably climb with more skill and less wasted effort, and they certainly experience enjoyment.Mountaineering is a sport which involves all the following things EXCEPT ______.
| A．hardship | B．comfort |
| C．physical risk | D．cold |

It is difficult for doctors to help a person with a damaged brain. Without enough blood, the brain lives for only three to five minutes. More often the doctors can’t fix the damage. Sometimes they are afraid to try something to help because it is dangerous to work on the brain. The doctors might make the person worse if he operates on the brain.
Dr. Robert White, a famous professor and doctor, thinks he knows a way to help. He thinks doctors should make the brain very cold. If it is very cold, the brain can live without blood for 30 minutes. This gives the doctor a longer time to do something for the brain.
Dr. White tried his idea on 13 monkeys. First he taught them to do different jobs, and then he operated on them. He made the monkeys' blood go through a machine. The machine cooled the blood. Then the machine sent the blood back to the monkeys' brains. When the brain’s temperature was 10°C, Dr. White stopped the blood to the brain. After 30 minutes he turned the blood back on. He warmed the blood again. After their operations the monkeys were like they had been before. They were healthy and busy. Each one could still do the jobs the doctor had taught them.The biggest difficulty in operating on the damaged brain is that _______.
| A．the time is too short for doctors |
| B．the patients are often too nervous |
| C．the damage is extremely hard to fix |
| D．The blood cooling machine might break down |
The brain operation was made possible mainly by _______.
| A．taking the blood out of the brain |
| B．trying the operation on monkeys first |
| C．having the blood go through a machine |
| D．lowering the brain’s temperature |
With Dr. White’s new idea, the operation on the damaged brain ______.
| A．can last as long as 30 minutes |
| B．can keep the brain’s blood warm |
| C．can keep the patient’s brain healthy |
| D．can help monkeys do different jobs |
