You know eating fruit and vegetables does good. But do you know it can also make you look good? People who increased their intake over just six weeks developed a healthy glow and appeared more attractive, researchers found. Scientists at St Andrews University found eating them slightly increased yellow and red pigments in the volunteers' skin. They monitored the food intake of 35 people and took pictures of their faces, arms and hands using a sensitive camera at the start, and after three and six weeks. Increasing their intake of greens by 2.9 portions a day was found to make the person look more healthy and an extra 3.3 portions could enhance their attractiveness, when their photographs were rated by others.
Fruit and vegetables are rich in carotenoids(类胡萝卜素)，which are known to protect against cell damage from pollution and UV rays, and can also prevent age-related diseases including heart disease and cancer. But while it was known eating extreme amounts of certain vegetables such as carrots could turn skin orange，it was not known a small increase was perceptible(被觉察）to others—and was seen as appealing.
A camera measured changes to the skin's redness, yellowness and lightness, and found it significantly changed in people who naturally increased their intake. These changes were not evident in three weeks. Using light sensors, the researchers showed these red and yellow hues were linked with the levels of carotenoids in their skin. There are hundreds of carotenoids but those thought to have the most dramatic effect are lycopene(番茄红素)—which gives tomatoes and red peppers their red colour—and beta-carotene found in carrots as well as broccoli, squash, and spinach. Skin colour is also affected by chemicals called polyphenols(多元酚)，found in apples, blueberries and cherries, which cause blood rush to the skin surface.What do we know from the research?

One hot night last July, when our new baby wouldn’t or couldn’t sleep, I tried everything I could think of : a warm bottle, songs gentle rocking. Nothing would settle him. Guessing that I had a long night ahead of me, I brought a portable TV into his room, figuring that watching the late movie was as good a way as any to kill of the hours till dawn. To my surprise, as soon as the TV lit up, the baby quieted right down, his little eyes focused brightly on the tube. Not to waste an opportunity for sleep, I then tiptoes out of the room, leaving him to watch the actors celebrate John Bellushi's forty-fifth birthday.
My wife and I heard none of the baby that night, and the next morning when I went into his room, I found him still watching TV himself.
I found in my baby's behavior a symbol of the new generation. My wife and I had given him some books to examine, but he merely spit upon them. When we read to him, he did not feel comfortable. And so it is in the schools. We find that our students don't read and they look down upon reading and scold those of us who teach it. All they want to do is watch TV. After this experience with the baby, however, I have reached a conclusion: “Let them watch it!” If television is that much more attractive to children than books, why should we fight about it? Let them watch it all they want! Why did the author bring a TV set into his son's room?
| A．To make his son keep quiet. |
| B．To spend the night by watching TV programs. |
| C．In order not to let his son feel lonely. |
| D．To make his son go to sleep as soon as possible. |

Our particular parenting style reflects our own way of “looking”. Here’s a great piece of writing reflecting parent’s particular ways on the parenting style that have become known humorously as helicopter parenting and submarine parenting.
Helicopter parents hover over their children, managing every aspect of their child’s life. On the contrary, submarine parents remain “hidden” coming to the surface when guidance is needed.
While helicopter parents may have the best intentions, in reality, they are raising children with few problem solving skills. Children with hovering parents never get the chance to face disappointment and build up their ability to recover from misfortune.
Think about your typical submarine. Submarines usually remain underwater. In case of a need for emergency surfacing, submarines can rise so quickly. They are driven partially out of the water. Submarine parents also remain out of sight, yet able to appear in the case of an emergency.
I admit I’m a submarine mom. My job as a parent is to have fun with my daughters while letting them explore and learn natural consequences. 
My older daughter found herself acting in commercials and making more than minimum wage as a teen. To give her a sense of the real world, I insisted she spend three weeks every summer, picking strawberries and earning $3.50 on a good day.
When my youngest daughter Sondra was six, she wanted a very expensive American Girl Doll. I cut the full color 18" picture out of the American Girl catalogue and had it laminated (压膜). “Here’s your American Girl Doll.” I said “When you turn nine, I’ll buy you the 3D doll on your birthday.” Sondra played with her flat doll for months, making clothes and furniture for her. She learned creativity. I saved $88.00.What is the text mainly about?
| A．Various means of transportation. |
| B．Funny experiences of a mom. |
| C．Humorous stories about parents. |

Who do you think breaks the law in our society? If you believe that only tough guys commit crimes, you may have to think again. Unlike in the movies, we can’t divide the world into bad guys and model citizens. Real life is much more complex. In the same way that diseases range from the common cold to fatal forms of cancer, crimes vary in degree. For example, smoking in an elevator will inconvenience people, but much less than threatening them with a gun.
In addition to breaking the law themselves, people tolerate various levels of crime. Why can we tolerate some crimes? It may be that, by seeing others do something, we accept it more easily. For instance, most people will find it easier to speed on a highway when everybody else is driving over the speed limit. When people celebrate a sports championship, if they see someone breaking store windows, they might start breaking windows themselves or even steal from the store. So the people around us influence how much law-breaking we can tolerate.
We must also wonder whether seeing violence on television or reading about it in the newspapers every day makes us tolerate crime more than we should. We become used to seeing blood on the news on television, or in full color in newspapers and magazines. Because we see thousands of dead people on TV, maybe we just try to ignore the situation behind the violence.
If so many citizens tolerate violence and crime, or even commit crimes themselves, it may simply be because of the human mind. Our minds may not care about specific laws. Instead, our minds may have a system of values that usually prevents us from hurting other people to improve our own lives. Yet, when it comes to respecting the rights of a mass of anonymous (不知名的) individuals, we might not be so responsible. While most people would not steal a wallet containing $50, they may not mind cheating on taxes, because cheating on taxes does not hurt any one person. It hurts society, but “society” remains an abstract idea that is not as real as a neighbor or a friend’s friend.
When we realize that so many people have misunderstandings of law-breaking, it is not surprising that so many people tolerate crimes, or even break laws, including me. But how could we improve the level of honesty in our society? Would strict laws help make our society better? Probably not. Honesty will have to come from social pressure: in the family, at school, on the job, each and every one of us can encourage honesty by showing which behavior is unacceptable. And teaching respect should become everyone’s responsibility. According to the author, “Real life is much more complex.” probably means .
| A．there is a wide range of people and crimes in the real life |

A Charlotte N.C. man was charged with first-degree murder of a 79-year-old woman whom police said he scared to death. Can the guy be held responsible for the woman’s death? Prosecutors (公诉人) said that he can under the state’s murder rule, which allows someone to be charged with murder if he or she causes another person’s death while committing or fleeing from a severe crime—even if he or she doesn’t kill someone on purpose.
But, medically speaking, can someone actually be frightened to death? We asked Martin Samuels, chairman of the neurology department at Brigham and Women’s Hospital in Boston.
Absolutely, no question about it.
The body has a natural protective method called the fight-or-flight response, which was originally described by Walter Cannon，chairman of Harvard University’s physiology department from 1906 to 1942. If, in the wild, an animal is faced with a life-threatening situation, the automatic nervous system responds by increasing heart rate, increasing blood flow to the muscles, and slowing digestion, among other things. All of this increases the chances of succeeding in a fight or running away from an aggressive beast. This process certainly would be of help to early humans. However, in the modern world there is obvious decline of the fight-or-flight response.
The autonomic nervous system uses the chemical messenger to send signals to various parts of the body to activate the fight-or-flight response. This chemical is poisonous in large amounts; it damages the organs such as the heart, lungs, liver and kidneys. It is believed that almost all sudden deaths are caused by damage to the heart. There is almost no other organ that would fail so fast as to cause sudden death.
By the way, any strong positive or negative emotions such as happiness or sadness can cause the same result. There are people who have died in excitement or in religious passion. There was a case of a golfer who hit a hole in one, turned to his partner and said, “I can die now”, and then he dropped dead. What is Martin Samuels’ attitude to the possibility of being frightened to death?
| A．Approval. | B．Disapproval. | C．Doubtful. | D．Indifferent. |
What can we learn about the fight-or-flight response according to the passage?
| A．The fight-or-flight response was raised and proved by Martin Samuels. |
| B．It is a natural protective method that can’t be found in all creatures but humans. |
| C．The ancient humans had a better fight-or-flight response than modern ones. |
| D．The fight-or-flight response is beneficial to both our actions and organs. |
What activity can we infer is less likely to damage the organs?
| A．Winning an unexpected fortune. |
| B．Missing a dead family member. |
| C．Watching a horror movie. |
| D．Listening to a sweet song. |
The purpose of the passage is ______.
| A．to explain why people will die of a heart attack |
| B．to offer some advice on protecting us from heart failure |
| C．to compare different kinds of feelings to cause a death |
| D．to show strong emotions can cause a sudden death |
