Not all think laughter is the best medicine, but it seems to help．So scientists carried on a new study of diabetes （糖尿病） patients who were given a good dose of humor for a year to prove it．
Researchers divide 20 high-risk diabetic patients into two groups．Both groups were given standard diabetes medicine．Group L viewed 30 minutes of humor of their choice, while Group C, the control group, did not．This went on for a year of treatments．
By two months into the study, the patients in the laughter group had lower level of the hormones epinephrine （肾上腺素）, considered to cause stress, which is known to be deadly．After the 12 months, HDL cholesterol rises 26 percent in Group L but only 3 percent in Group C．In another measure, C-reactive proteins, a maker of heart disease, drop 66 percent in the laughter group but only 26 percent in the control group．
“The best doctors believe that there is a physical good brought about by the positive emotion, happy laughter,” said study leader Lee Berk of Loma Linda University．And other research has found that humor makes us more hopeful．Still, more study is needed, Berk said．The research by Berk found that humor can bring about similar changes in body chemistry, which was proved in the new study．The research result will be presented this month at the meeting in the US．Research at the University of Maryland School of Medicine shows that laughter causes the inner lining of blood vessels to expand, increasing blood flow in a way thought to be healthy．
“Lifestyle choices have an important effect on health and these are choices which we and patients should pay attention to, rather than prevention and treatment,” Berk said in a statement this week．Why did the scientists carry on the new research?
| A．To find out if laughter was good to health． |
| B．To discover the best medicine to cure diabetes． |
| C．Because the number of diabetic patients is the largest in the world． |
| D．Because diabetic patients need more laughter than other patients． |
After 12 months into the study, ___________．
| A．C-reactive proteins increase 66 percent in Group C |
| B．the level of the hormones epinephrine stays the same in both groups |
| C．the level of the hormones epinephrine has dropped |
| D．C-reactive proteins reduced 66 percent in Group L |
The underlined part “HDL cholesterol” in Paragraph 3 must be _______．
| A．something bad to our health | B．something good to our health |
| C．a kind of wonderful medicine | D．a kind of dangerous disease |
In what way does laughter benefit people’s health?
| A．Blood is made thick by laughter． |

There once was a very honest shopkeeper whose business was to provide goods to the local people. He would open his shop at 8:00 a.m. after having his breakfast and at 1:00 p.m. he would go for lunch. In the evening at 8:30 p.m. he closed his shop to complete his daily routine.
However, to get time for lunch was really difficult because he didn’t have anybody to help him at that time. Therefore, it was his daily practice that whichever customer was shopping at 1:00 p.m. would be asked to oversee (看管) the shop until the shopkeeper returned from lunch.
One day, a group of four thieves planned to steal from his shop while he was gone for lunch. One of the thieves went at 1:00 p.m. to be the customer that would be asked to oversee the shop.
The thief, pretending to be a customer, went in at 1:00 p.m. and started buying several items. As planned, the shop-keeper asked the thief to sit on his chair for thirty minutes until he returned from lunch.
Then, the other three thieves quickly came and told the pretended customer to help, but something had changed within him and he knew deeply in his heart that if he was given responsibility for the shop, he should not perform any dishonest acts during that time. His friends did not agree. As the now honest man tried to stop them, they resisted (抵抗) and a fight started. And at the same time the shopkeeper returned and asked why there was a fighting. The now honest man explained the entire plan.

A young man returns to his hometown of Aractataca, Colombia. He visits the house where he lived as a child. Here, he remembers the most important memories of his childhood. Standing in front of his old house, the young man makes an important decision. He says to himself, “I will start my life over again. I will become a writer.”
This man is the world famous writer, Gabriel Garcia Marquez.
Gabriel Garcia Marquez was born on March 6, 1928. During his early life, Garcia Marquez’s grandmother and grandfather told him many stories. His grandmother would tell him legends as if they were real. Garcia Marquez says that his grandmother’s way of storytelling later influenced his own methods.
When Garcia Marquez was about 20 years old, he left Aractataca and attended university in Bogota. He began studying law because this was what his father wanted him to study. However, Garcia Marquez was not happy.
During this time Garcia Marquez returned to Aractataca. It was on this visit that he realized he must stop studying law. And he recognized that he must return to the dream of his childhood-writing. For the next few years, Garcia Marquez wrote for many different newspapers. And in 1955, he published his first book called “Leaf Storm”.
For many years, Garcia Marquez knew he wanted to write about his grandfather’s house in Aractataca. To write this book, Garcia Marquez and his wife had to sell almost all of their possessions to survive. But their act was worth it. The book, “One Hundred Years of Solitude” was immediately successful. And this book created a path for Garcia Marquez’s future success.

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.
"Orange fruits and vegetables also play a part in preventing cancer, particularly of the lungs and stomach. Foods that contain the color orange are: Carrots, mangoes, sweet potatoes, pumpkins, etc.The passage tries to tell us that ______.
| A．colors mean a lot to people and their health |

| C．carotene | D．vitamin K |
It can be inferred from the passage that _______.
| A．all grapes help lower the risk of high blood pressure and cancer |
| B．lung cancer can be prevented by eating red-colored foods |
| C．green-colored foods contain a lot of vitamin A which is good for eye health |
| D．tomatoes should be eaten cooked so that we can benefit the most |
More and more people take part in marathons these days – over 30,000 people will run the London Marathon this weekend, for instance. But it’s not just the 26 miles and 385 yards that could be a daunting prospect. “I have to admit to being completely frustrated by the blocking and for 18-19 miles was just keeping away from people and being held up,” one participant grumbled after the 2012 London Marathon. “I had to overtake a lot of people and ended up with bruised（淤肿的）forearms from all the elbows,” said another.
How do such crowding problems arise, and could they be reduced? Some researchers believe that we can find the answers through a more familiar system in which jams appear – road traffic flow. Martin Treiber, of the Technical University of Dresden in Germany, has previously developed models for traffic flow. One of the first attempts to model traffic flow was made in the 1950s by James Lighthill and his collaborator Gerard Whitham of Manchester University. They considered the traffic as a kind of liquid flowing down a pipe, and looked at how the flow changes as the fluid gets denser(浓稠). At first the flow rate increases as the density increases, since you simply get more stuff through in the same period of time. But if the density becomes too high, there’s a risk of jams, and the flow rate drops sharply.
Treiber’s model of a marathon uses this same principle that the flow rate first increases and then decreases as the density of runners increases, thanks to an sudden switch from free to crowded flow. He assumes that there is a range of different preferred speeds for different runners, which each maintains throughout the race. With just these factors, Treiber can calculate the flow rate of runners, knowing the “carrying capacity”(承载能力)at each point on the route.
This allows Treiber to figure out how blocking might depend on the race conditions – for example, for different starting procedures. Some marathons start by letting all the runners set off at once (which means those at the back have to wait until those in front have moved forward). Others assign runners to various groups according to ability, and let them start in a series of waves.
Treiber has applied the model to the annual Rennsteig half-marathon in central Germany, which attracts around 6,000 participants. The traditional route had to be changed in 2013, because the police were no longer willing to close a road to ensure that runners could cross safely. It could pass either over a 60m wooden bridge or through a tunnel. Treiber used his model to predict the likely blocking caused in the various options. The model predicted that a mass start would risk an overload of runners if the bridge were to be used. Only by moving the starting point further back from the bridge could the danger be avoided – and even then, if some of the numbers assumed in the model were only slightly inaccurate, there was still a risk of jams at the bridge. On the other hand, no dangerous blocking seemed likely for the tunnel route. The run organizers consulted Treiber’s team, and eventually chose this option.What is the worst thing while running a marathon?
| A．The long distance. |
| B．Too many participants. |
| C．The dangerous blocking. |
| D．Serious injuries in forearms. |
Which of the following statements is true?
| A．James Lighthill is the first expert trying to model traffic flow. |
| B．The denser the flow is, the faster the flow rate becomes. |
| C．The flow rate increases in the beginning because fewer people passed together. |
| D．The flow rate increases first and then decreases later when the flow is too denser. |
What is NOT true about the Rennsteig?
| A．It has much less participants than the London Marathon in 2014. |
| B．It has a shorter distance than the London Marathon. |
| C．The route was changed because the traditional one is not safe any longer. |
| D．The participants running this marathon will pass a tunnel because this choice is safer. |
What’s the main idea of the passage?
| A．Make a comparison between marathon and road traffic. |
| B．Running a marathon is somewhat dangerous if it is not well organized. |
| C．Introduce a new technology to solve the blocking problem in marathon. |
