Chocolate is good for your heart, skin and brain. Usually, people think that chocolate is bad for their health. They describe chocolate as “something to die for” or say “death by chocolate”．Now they should bite their tongues! Evidence(证据) is showing that some kinds of chocolate are actually good for you in the following ways:
A happier heart
Scientists at Harvard University recently examined 136 studies on cocoa—the main ingredient in chocolate and found that it does seem to strengthen the heart．Studies have shown heart benefits from increased blood flow．These benefits are the result of cocoa’s chemicals, which seem to prevent both cell damage and inflammation(炎症)．
Better blood pressure
If yours is high, chocolate may help．Jeffrey Blumberg from Tufts University recently found that people with high blood pressure who ate 3.5 ounces of dark chocolate per day for two weeks saw their blood pressure drop quickly．
Muscle magic
Chocolate milk may help you recover after a hard workout(锻炼)．In a small study at Indiana University, people who drank chocolate milk between workouts did better on a tiredness test than those who had some sports drinks．
Better for your skin．German researchers gave 24 women a half-cup of special cocoa every day．After three months, the women’s skin was moister(滑润的)and smoother．The research shows that chocolate helps protect and increase blood flow to the skin, improving its appearance．
Brain gains
It sounds almost too good to be true, but research suggests that chocolate may improve your memory, attention span, reaction time, and problem-solving by increasing blood flow to the brain．Which of the following is wrong?
| A．Coca’s chemicals can prevent both cell damage and inflammation. |
| B．Chocolate may help you lower your blood pressure. |
| C．People early know chocolate is good for their health. |
| D．chocolate may improve your memory, attention span, reaction time, and problem-solving. |

Perhaps you think you could easily add to your happiness with more money. Strange as it may seem, if you're unsatisfied, the issue is not a lack of means to meet your desires but a lack of desires—not that you cannot satisfy your tastes but that you don't have enough tastes.
Real riches consist of well-developed and hearty capacities (能力) to enjoy life. Most people are already swamped(淹没) with things. They eat, wear, go and talk too much. They live in too big a house with too many rooms, yet their house of life is a hut.
Your house of life ought to be a mansion (豪宅) , a royal palace. Every new taste, every additional interest, every fresh enthusiasm adds a room. Here are several rooms your house of life should have.
Art should be a desire for you to develop simply because the world is full of beautiful things. If you only understood how to enjoy them and feed your spirit on them, they would make you as happy as to find plenty of ham and eggs when you're hungry.
Literature, classic literature, is a beautiful, richly furnished room where you might find many an hour of rest and refreshment. To gain that love would go toward making you a rich person, for a rich person is not someone who has a library but who likes a library.
Music like Mozart's and Bach's shouldn't be absent. Real riches are of the spirit. And when you've brought that spirit up to where classical music feeds it and makes you a little drunk, you have increased your thrills and bettered them. And life is a matter of thrills.
Sports, without which you remain poor, mean a lot in life. No matter who you are, you would be more human, and your house of life would be better supported against the had days, if you could, and did, play a bit.
Whatever rooms you might add to your house of life, the secret of enjoying life is to keep adding.The author intends to tell us that____________.
| A．true happiness lies in achieving wealth by fair means |
| B．big houses are people's most valued possessions |
| C．big houses can in a sense bring richness of life |
| D．true happiness comes from spiritual riches |
The underlined sentence in the second paragraph probably implies that__________.
| A．however materially rich, they never seem to be satisfied |
| B．however materially rich, they remain spiritually poor |
| C．though their house is big, they prefer a simple life |
| D．though their house is big, it seems to be a cage |
Larry was on another of his underwater expeditions(探险)but this time, it was different. He decided to take his daughter along with him. She was only ten years old. This would be her first trip with her father on what he had always been famous for.
Larry first began diving when he was his daughter’s age. Similarly, his father had taken him along on one of his expeditions. Since then, he had never looked back. Larry started out by renting diving suits from the small diving shop just along the shore. He had hated them. They were either too big or too small. Then, there was the instructor. He gave him a short lesson before allowing him into the water with his father. He had made an exception. Larry would never have been able to go down without at least five hours of theory and another similar number of hours on practical lessons with a guide. Children his age were not even allowed to dive.
After the first expedition, Larry’s later diving adventures only got better and better. There was never a dull moment. In his black and blue suit and with an oxygen tank fastened on his back, Larry dived from boats into the middle of the ocean. Dangerous areas did not prevent him from continuing his search. Sometimes, he was limited to a cage underwater but that did not bother him. At least, he was still able to take photographs of the underwater creatures.
Larry’s first expedition without his father was in the Cayman Islands. There were numerous diving spots in the area and Larry was determined to visit all of them. Fortunately for him, a man offered to take him around the different Spots for free. Larry didn’t even know what the time was, how many spots he dived into or how many photographs he had taken. The diving spots afforded such a wide array of fish and sea creatures that Larry saw more than thirty varieties of creatures.
Larry looked at his daughter. She looked as excited as he had been when he was her age. He hoped she would be able to continue the family tradition. Already, she looked like she was much braver than had been then. This was the key to a successful underwater expedition.What can be inferred from Paragraph2?
| A．Larry had some privileges. |
| B．Larry liked the rented diving suits. |
| C．Divers had to buy diving equipment. |
| D．Ten-year-old children were permitted to dive. |
Why did Larry have to stay in a cage underwater sometimes?
| A．To protect himself from danger. |
| B．To dive into the deep water. |
| C．To admire the underwater view. |
| D．To take photo more conveniently. |
Recordings of angry bees are enough to send big, tough African elephants running away, a new study says. Beehives (蜂窝)-either recorded or real-may even prevent elephants from damaging farmer's crops.
In 2002, scientist Lucy King and her team found that elephants avoid certain trees with bees living in them. Today, Lucy wants to see if African honeybees might discourage elephants from eating crops. But before she asked farmer to go to the trouble of setting up beehives on their farms, she needed to find out if the bees would scare elephants away.
Lucy found a wild beehive inside a tree in northern Kenya and set up a recorder. Then she threw a stone into the beehive, which burst into life. Lucy and her assistant hid in their car until the angry bees had calmed down. Next，Lucy searched out elephant families in Samburu National Reserve in northern Kenya and put a speaker in a close to each family.
From a distance, Lucy switched on the pre-recorded sound of angry bees while at the same time recording the elephants with a video camera. Half the elephant groups left the area within ten seconds. Out of a total of 17 groups, only one group ignored the sound of the angry bees. Lucy reported that all the young elephants immediately ran to their mothers to hide under them. When Lucy Played the sound of a waterfall (瀑布) instead of the angry bees to many of the same elephant families, the animals were undisturbed. Even after four minutes, most of the groups stayed in one place.
Lucy is now studying whether the elephants will continue to avoid the sound of angry bees after hearing it several times. She hasn't tested enough groups yet to know, but her initial (最初的) results were promising enough to begin trials with farmers. She has now begun placing speakers in the fields to see if elephants are frightened away.As mentioned in the passage, Lucy

| B．To make a video of elephants. |
| C．To see if elephants would run away. |
| D．To find out more about the behavior of bees. |
Which of the following is true according to the passage?
| A．Young elephants ignore African honeybees. |
| B．Waterfalls can make elephants stay in one place. |
| C．Elephants do not go near trees with bees living in them. |

The idea of being able to walk on water has long interested humans greatly. Sadly, biological facts prevent us ever accomplishing such a thing without artificial aid --- we simply weigh too much, and all our mass pushes down through our relatively small feet, resulting in a lot of pressure that makes us sink.
However, several types of animals can walk on water. One of the most interesting is the common basilisk Basilicus basilicus, a lizard（蜥蜴）native to Central and South America. It can run across water for a distance of several meters, avoiding getting wet by rapidly hitting the water’s surface with its feet. The lizard will take as many as 20 steps per second to keep moving forward. For humans to do this, we’ll need huge feet that we could bring up to our ears in order to create adequate “hitting.”
But fortunately there is an alternative: cornflour. By adding enough of this common thickening agent to water (and it does take a lot), you can create a “non-Newtonian” liquid that doesn’t behave like normal water. Now if the surface of the water is hit hard enough, particles（粒子）in the water group together for a moment to make the surface hard. Move quickly enough and put enough force into each step, and you really can walk across the surface of an adequately thick liquid of cornflour.
Fun though all this may sound, it’s still rather messy and better read about in theory than carried out in practice. If you must do it, then keep the water wings handy in case you start to sink --- and take a shower afterward!What do we know about Basilicus basilicas from the passage?
| A．It is light enough to walk on water. |
| B．Its huge feet enable it to stay above water. |
| C．It can run across water at a certain speed |
| D．Its unique skin keeps it from getting wet in water |
What is the function of the cornflour according to the passage?
| A．To create a thick liquid. |
| B．To turn the water into solid. |
| C．To help the liquid behave normally. |
| D．To enable the water to move rapidly. |
What is the author’s attitude toward the idea of human’s walking on water?
| A．It is risky but beneficial. |
| B．It is interesting and worth trying |
| C．It is crazy and cannot become a reality |
| D．It is impractical though theoretically possible |
According to the dictionary definition of "create "，ordinary people are creative every day. To create means " to bring into being, to cause to exist"-something each of us does daily.
We are creative whenever we look at or think about something in a new way. First, this includes an awareness （意识）of our surroundings. It means using all of our senses to become aware of our world. This may be as simple as being aware of color and texture（质地），as well as taste, when we plan a meal. Above all, it is the ability to notice things that others might miss.
A second part of creativity is an ability to see relationships among things. If we believe the expression，"There is nothing new under the sun，" the creativity is remaking or recombining（重组）the old in new ways. For example, we might do this by finding a more effective way to study or a better way to arrange our furniture, or we might make a new combination of camera lenses and filters to create an unusual photograph.
A third part of creativity is the courage and drive to make use of our new ideas, to ask for them to achieve some new results. To think up a new idea is one thing; to put the idea to work is another.
These three parts of creativity are included in all the great works of geniuses, but they are also included in many of our day-to-day activities.Which of the following activities is NOT a creative one according to the passage?
| A．To prepare for a meal. |
| B．To arrange the furniture in a special way. |
| C．To buy some books from a bookstore. |
| D．To "write" a letter with the computer. |
"There is nothing new under the sun" really implies that __________.
| A．a new thing can only be created at the basis of earliest things |
| B．a new thing is only a tale |
| C．we can seldom create new things |
| D．we can hardly see really new things in the world |
What does the author think about the relationship between a new thought and its being put into practice?
| A．It's more difficult to create a new thought than to use it in practice. |
| B．To find a new thought will clearly lead to the production of a new thing. |
| C．A man with an excellent ability of practice can easily become an inventor. |
| D．One may come up with a new thought, but cannot put it into practice. |
The best title for this passage is __________.
| A．How to Cultivate One's Creativity |
| B．What Is Creativity |
| C．The Importance of Creativity |
| D．Creativity a Not Faraway Thing |
