Tears are nature's way of making us feel more comfortable. When our eyes is made uncomfortable by some small pieces of pollution, or when we are cutting onions, or when we are exhausted and “red –eyes” from over work and late hours, tears form in our eyes to clean and re-flesh 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 uniquely（唯独）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 make up 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 animal is the end product of a long evolutionary process that began in the sea.
And it is clear that, in addition to（除了） the emotional benefits（好处）, 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 create 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.

The connection shared by grandparents and grandchildren is something very special and despite the changing family situation, it still remains strong across generations. For most of us, our grandparents were our first best friends, the ones with whom we shared our secrets and our pain.
In majority of the cases, grandparents would have babysat their grandchildren while parents were busy working and didn't have much time for their children. Even as a kid grows up, the love and affection for grandparents never dies, and for many teens, visiting grandparents or living with them in the same house is a pleasure. Kedar Patwary, a mass communication student, says, "I often end up having long conversations with my grandfather about the evolution of Indian society and I really admire him for the patience with which he answers all my questions. "
Many teenagers feel that their parents treat them as grown-ups, while their grandparents give them much freedom.
Leela Narayanan, a grandmother. says that she loves to pamper her grandchildren and cook favorite dishes for them. She further adds that her eldest granddaughter, who is now 19, was brought up by her till she was four and the closeness they shared remains the same even now。
At times, the gap m generations plays a negative role, when grandparents find it difficult adjusting to the modern lifestyle. Technology is what works against this relationship. Youngsters' eing crazy about with gadgets leaves them with no time for their loved ones.

Almost anywhere in the world, you can probably see graffiti (涂鸦画). Although it’s usually more common in big cities, it can be found in almost any community, big or small.
The problem with graffiti art is the question of whether it’s really art. This isn’t always an easy question to answer, simply because there are so many different types of graffiti. While some simply consists of collections of letters, known as tags, with little artistic value, such examples are easy to find, especially on larger spaces such as walls.
If it weren’t for the fact that most graffiti is placed on private property without permission, it might be more commonly recognized as a legal form of art. Most graffiti, however, annoys the property owner, who is more likely to paint over it or remove it than accept it as art.
Many ways of removing graffiti have been developed, such as paints that dissolve graffiti paint, or make it easy to remove. Community groups and government departments often organize graffiti-removal teams.
It hardly makes sense to encourage artists to deface (丑化) private or public property; but perhaps there are ways to work with them rather than just oppose them. Graffiti artists can, for example, create murals (壁画) for property owners, and get paid for them.
Maybe we need to start at a very basic level, and find a way to encourage the creation of graffiti art on paper or canvas rather than on walls. After all, who would remember Monet or Picasso if they’d created their masterpieces on walls, only to have them painted over the next day? Finding a solution to such a complex problem is never going to be easy, but with more and more graffiti art being recognized in galleries around the world, we do need to try.What would be the best title for this passage?
| A．How to Be a Good Graffiti Artist. |
| B．Stop Removing Graffiti! |
| C．Do You Like Graffiti? |
| D．Is Graffiti Art? |
The reason why people remove graffiti is that it ______.
| A．makes buildings ugly | B．has no artistic value at all |
| C．robs private property | D．takes up too much space |
In Paragraph 4, the underlined word "dissolve" is closest in meaning to ______.
| A．change | B．flow | C．remove | D．freeze |
The example of Monet and Picasso are mentioned in the passage to indicate that ______.
| A．they are world-famous artists |
| B．they are good at graffiti |
| C．walls are right places to keep their masterpieces |
| D．their works, if painted on the wall, might not be kept long |
The writer’s attitude toward graffiti is that graffiti ______.
| A．should be removed by more countries |
| B．should be saved on larger spaces |
| C．should be created only on paper or canvas |

Like most Oregonians, Stephanie McRae was used to driving in bad weather. Although rain still beat the window of her car, the worst of the day’s storm seemed to have passed as she drove her 11-year-old daughter, Maggie, home from a church at 8:30 p.m. Two little children sat into their car seats in back.
When crossing over Fawcett Creek (小河), McRae found the road just ahead had been washed away. The storm had turned Fawcett Creek into a 100-feet-wide river. Water began to go into the car and the four of them had to climb onto the car’s roof. The car was floating about and was being swept toward the Tillamook River only a few miles ahead. Suddenly it stopped when hitting a logjam (浮木阻塞).The water swept over them, rising higher and higher. Stephanie screamed into the rainy night, almost crying.
“Mom, I have to go and get help,” her 11-year-old daughter Maggie cried.
Stephanie realized if she went by herself, Maggie couldn’t hold on to the other two babies. But Maggie was still recovering from foot surgery. How could she manage? Finally she shouted, “I’m proud of you. Be careful!”
As Maggie McRae struggled to reach the shore, she was all wet. The sixth grader started running to the nearest house. Inside, the neighbors immediately called 911 and were told that firefighters were making their way toward another trapped car. Maggie joined the neighbors, and helped the rescue team point out where her mother was. Thefirefighters saved McRae and her children by using a 35-foot-long ladder.

Eating different colored foods can keep you healthy, as well as change your mood and behavior. Here is a list of colors, which can change your life.
Blue/Purple
Blue is considered to be peaceful and calming and it has the same effect on our health. The blue / purple color in food is due primarily to their anthocyanins which are antioxidants (抗氧化剂) that are particularly heart healthy and may help support healthy blood pressure. Out of all the blue and purple foods available, blueberries are considered to have the highest antioxidant level. An analysis of the latest data from the National Health and Nutrition Examination Study found that people who eat purple and blue fruits and vegetables are at a reduced risk for high blood pressure and are less likely to be overweight.
A food and health expert says that blue and purple color foods can prevent blood mass formation, and they also lower the risk of cancer.
Foods that contain blue and purple colors are: reddish eggplant (especially the skin), blueberries, blackberries, purple grapes, etc.
Green
We all know that we should eat green as green symbolizes nature. The green foods are rich in isothiocyanates, which help resist cancer.
Dr. Ashok Agarwal, a food and nutrition specialist, explains, "They are excellent sources of folic acid, vitamin K, as well as carotene （胡萝卜素）. Diets high in those above are associated with lowered blood pressure."
Foods that contain the green color are: broccoli, cabbage, cucumbers, etc.
Red
Lycopene (番茄红素) in reddish fruits and vegetables is a powerful antioxidant that has been associated with a reduced risk of some cancers, and also provides protection against heart attacks.
Dr. Smiths says, "Cooked tomato sauces are associated with greater health benefits as compared with the uncooked version as the heating process allows lycopene to be more easily absorbed by the body. Obtaining the most benefit from food depends on proper selection, storage and cooking of the produce."
Foods that contain red color are: Tomatoes and tomato products, watermelon, guava, red onions, red chili, red apples, red grapes, cherries, etc.
Orange
The orange foods are also rich in carotene, which are particularly good antioxidants. These foods are commonly considered eyesight foods because they contain vitamin A.

How far would you be willing to go to satisfy your need to know? Far enough to find out your possibility of dying from a terrible disease? These days that’s more than an academic question，as Tracy Smith reports in our Cover Story.
There are now more than a thousand genetic(基因的)tests，for everything from baldness to breast cancer，and the list is growing．Question is do you really want to know what might eventually kill you? For instance，Nobel Prize-winning scientist James Watson，one of the first people to map their entire genetic makeup, is said to have asked not to be told if he were at a higher risk for Alzheimer’(老年痴呆症)．
“If I tell you that you have an increased risk of getting a terrible disease，that could weigh on your mind and make you anxious，through which you see the rest of your 1ife as you wait for that disease to hit you．It could really mess you up．”Said Dr．Robert Green，a Harvard geneticist.
“Every ache and pain，”Smith suggested，could be understood as“the beginning of the e nd．”“That’s right．If you ever worried you were at risk for Alzheimer's disease，then every time you can’t find your car in the parking lot，you think the disease has started．”
Dr．Green has been thinking about this issue for years．He led a study of people who wanted to know if they were at a higher genetic risk for Alzheimer’s．It was thought that people who got bad news would，for lack of a better medical term，freak out．But Green and his team found that there was “no significant difference”between how people handled good news and possibly the worst news of their lives．In fact，most people think they can handle it．People who ask for the information usually can handle the information，good or bad，said Green．The first paragraph is meant to ．
| A．ask some questions | B．introduce the topic |
