When we see well, we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are.
People who are near-sighted can only see things that are very close to their eyes. Everything else seems blurry (unclear). Many people who do a lot of work, such as writing, reading and sewing become near--sighted.
People who are far-sighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm’s length. If they want to do much reading, they must get glasses, too.
Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism (散光). This, too, can be corrected by glasses. Some people’s eyes become cloudy because of cataracts (白内障). Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.
Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle. To prove this to yourself, look at an object out of one eye; then look at the same object out of your other eye. You will find the object’s relation to the background and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distance as people with two eyes.We should take good care of our eyes ___ .
| A．only when we can see well |

Dr Wiseman started “the laugh lab” project in September 2001. It is the largest study of humour. Participants(参加者)are invited to log onto the laugh lab website, give a few personal details, tell their favourite jokes and judge the jokes told by other people.
The project will last for a year, and the organizers hope to finally discover the world's funniest joke. But there is also a serious purpose. The researchers want to know what people from different nations and cultures find funny. And they want to find out the differences between the male and female sense of humour. The idea is that if we want to understand each other, we have to find out what makes us laugh.
This is a subject that has long interested psychologists(心理学家)and philosophers(哲学家). Most of the time, people are not completely honest. We do things that society expects us to and say things that help us get what we want. But laughing cannot be controlled. When we laugh, we tell the truth about ourselves.
By December 2001 over 10,000 jokes had been submitted. This gave the scientists enough evidence(证据)to make early conclusions. It seems that men and women do have different senses of humor, for instance.
“Our findings show the major differences in the ways in which males and females use humour，”said Dr Wiseman. “Males use humour to appear superior(优越)to others, while women are more skilled in languages and prefer word play.”
Researchers also found that there really is such a thing as a national sense of humour. The British enjoy what is usually called “toilet humor”. But the French like their jokes short and sharp：“You're a high priced lawyer. Will you answer to questions for $ 500？”“Yes. What's the second question？”
The Germans are famous for not having a sense of humor. But the survey found that German participants were more likely to find submitted jokes funny than any other nationality. Perhaps that provides the point. Is this joke funny? I don't know, but let's say yes, just to be safe.
Dr Wiseman and his workmates also submitted jokes created by computer. But none of those who took part in the survey found any of them amusing. Perhaps this is relief. Computers already seem like they can do everything. At least they should leave the funny stuff to us.Scientists started “the laugh lab” project________.
| A．to find the funniest joke in European countries. |
| B．to know what funny people are from different nations and cultures |
| C．to find out the differences between the male and female sense of humor |
| D．to get more personal details about participants |

| B．psychologists and philosophers take interest in “the laugh lab” project |
| C．ordinary people are not interested in “the laugh lab” project at all |

In early October, thousands of people around the globe stepped outside to gaze at their local night sky. As part of an event called the Great World Wide Star Count, adults and kids of looked for one of two constellations(星群)—Cygnus in the Northern Hemisphere and Sagittarius in the Southern Hemisphere. The observers recorded how many stars they saw and how bright the stars were, and then posted their results online.
The Star Count was part of global effort to help scientists learn more about how light pollution affects our view of the night sky. Whether participants saw thousands of stars—or just a dozen—depended a lot on whether they were surrounded by darkness or by twinkling city lights.
Dark spots on the map, above, show the locations of people who participated in the first annual Great Worldwide Star Count. Over 2 weeks, people in 64 countries made 6,624 observations.
On a clear night, with no clouds, moonlight, or artificial lights to block the view, people can see more than 14,000 stars in the sky, but when people are surrounded by city lights they're lucky to see 150 stars.
If you've ever driven toward a big city at night and seen its glow from afar, you're witnessed light pollution. It occurs when light from streetlights, office buildings, signs, and other sources streams into space and illuminates the night sky. This light makes many stars invisible to people on Earth.
Dust and particles of pollution from factories and industries worsen the effects of light pollution. When these particles float into the atmosphere, light ricochets(跳飞)off of them and scatters even more.
Light pollution doesn't fly affect star visibility. It can harm wildlife too. Scientists don't entirely understand how animals navigate at night, but it's clear that artificial light can attract them, making them go off course. There's increasing evidence, for example, that migrating birds use sunsets and sunrises to help find their way.Why did do many people look at the local sky?
| A．To enjoy the beauty of the stars. |
| B．To develop their interest in Astronomy. |
| C．To help scientists do a research on light pollution. |
| D．To get the exact number of star in the sky. |
When people are surrounded by artificial lights, ________.
| A．they can find more stars in the sky |
| B．the stars might appear more clearly |
| C．the stars seem to be bigger |
| D．they can find far fewer stars |
What does the word “illuminates” probably means in this passage?
| A．make...bright |
| B．make...invisible |
| C．make...beautiful |
| D．make...clear |
How does light pollution affect birds?
| A．It does great harm to their eyes at night. |
| B．It mistakes them the way when they migrate. |
| C．It can enable them to see their routes clearly. |
| D．It can make them find their way easily. |
According to the maps above, which continent has fewest participants in the Star Count?
| A．North America. |
| B．Australia. |
| C．South America. |
| D．Africa. |

Tears are nature's way making us feel comfortable. When our eyes are made uncomfortable by some small pieces of pollution, or when we are cutting onions, or when we are exhausted and “red-eyes” from overwork and late hours, tears from in our eyes to clean and refresh them.
Tears are also a sign of strong emotion. We cry when we are sad and we cry when we are happy.
And tears seem to be uniqueness(唯一)of human. We know that animals also experience emotion—fear, pleasure, loneliness—but they do not shed(流)tears. From this we can conclude that tears are closely related to the emotional and biological makeup of the human species.
Biologically speaking, tears are actually drops of saline fluid, which is a little bit salty, produced by a gland(腺)in the body. Because salt is an important component, tears may actually constitute the most conclusive evidence that the human animals are the end product of a long evolutionary(进化的)process that began in the sea.
And it is clear that, in addition to(除了)the emotional benefits, the shedding of tears has a specific biological function as well. Through tears, we can eliminate from our body certain chemicals which build up in response to stress and cerate a chemical imbalance in the body. Crying actually makes us feel better by correcting that imbalance and making us feel good again. And thus the emotional and the biological functions of tears merge(合并)into one and make us even more “human” than we would otherwise be.According to the passage, human beings may have originated in________.
| A．the sea |
| B．the salt |
| C．chemicals |
| D．animals |
Which of the following is NOT a function of tears?
| A．Biological. |
| B．Emotional. |
| C．Political. |
| D．Chemical. |
According to the article, which of the following is unique to humans?
| A．The feeling of loneliness. |
| B．The state of feeling good. |
| C．The ability to shed tears. |
| D．The feeling of fear. |
The word “eliminate” probably means________.
| A．add |
| B．produce |
| C．replace |
| D．remove |

The human nose has given to the language of the world many interesting expressions. Of course this is not surprising. Without the nose we could not breathe or smell. It is the part of the face that gives a person special character. Cyrano De Bergerac said that a large nose showed a great man—brave, polite, manly, and bright. A famous woman poet wished that she had two noses to smell a rose. Blaise Pascal, a French philosopher(哲学家)made an interesting comment about Cleopatra's nose. “If it had been shorter，”he said，“it would have changed the whole face of the world.”Historically, man's nose has had an important role in his imagination. Man has referred to the nose in many ways to express his feelings. Expressions about the nose refer to human weakness, anger, pride, jealousy(嫉妒)and revenge(报复). In English there are a number of phrases about the nose. For example, “To_hold_up_one's_nose” expresses a basic human feeling—pride. People can hold up their noses at people, things and places. The phrases, to be led around by the nose, shows man's weakness. A person who is led around by the nose lets other people control him. On the other hand, a person who follows his nose, lets his instinct guide him.
For the human emotion of rejection, the phrase to_have_one's_nose_put_out_of_joint is very descriptive. The expression applies to persons who have been turned aside because of a competitor. Their pride is hurt and they feel rejected. This expression is not new. It was used by Erasmus in 1542.

Camp memories last forever! We make sure they are unforgettable!
Shadow Ridge Summer Camps offer so many exciting things for campers to do. Unlike other camp programs that include horses as a small part of their program, at Shadow Ridge horses ARE the program! We are 100% horse from stable(马厩)management, nature walks, and track rides to bedroom furnishings.
Horses help us achieve many of our aims. Girls can learn to develop responsibility, self-confidence and personal connections in their lives while having fun. Using horses as a wonderful tool for education, our camps offer an interesting place for growth and learning.
Imagine each girl having her very own horse to spend time with and a best friend to love and take care of. Each camper is responsible for a horse for the week. Our riding program provides a lot of riding and lesson time. Campers will learn how to take care of the horse and the tack(马具), as well as how to ride. Days are filled with horse-related activities to strengthen the connection between each girl and horse, as the girls learn to work safely around the horses.
At Shadow Ridge we try to create a loving, caring family atmosphere for our campers. We have “The Bunkhouse”(4 girls), the “Wranglers Roost”(4 girls), and “The Hideout”(2 girls)in our comfortable 177yearold farm house. All meals are home cooked, offering delicious and healthy food for the hungry rider.
Our excellent activities create personalized memories of your child's vacation. Each child will receive a camp T-shirt and a photo album(usually 300～500 pictures)of their stay at camp.
