British researchers are looking for volunteers willing to eat a piece of chocolate daily for a year in the name of science. The trial(实验) will explore whether flavonoids (类黄酮) found in chocolate and other foods can reduce the risk of heart disease.
“We are looking at a high risk group first,” said Aedin Cassidy, a biochemist who will lead the study.
Previous studies have suggested dark chocolate is rich in the beneficial flavonoids linked with heart health, but experts note the high sugar and fat content of most commercially available chocolate might cancel out some of the advantages. Other research has also shown dark chocolate appears to lower blood pressure, improve the function of blood vessels (血管)and reduce the risk of heart attack.
This has encouraged companies to market specific products containing dark chocolate. Mars Inc has introduced Cocoa Via, a line of dark and premium chocolates that plays up such health advantages.
Cassidy said her team will also publish findings in the American Journal of Clinical Nutrition showing that flavonoids found in soy and cocoa appear to have the strongest effects of reducing risk of heart disease.
The next step will organize 150 women volunteers with a specific illness. The researchers will look at whether flavonoids help reduce blood pressure, cut cholesterol levels and improve the condition of blood vessels.
Half the women in the year-long study will eat chocolate containing 30 grams of flavonoids found in soy, cocoa and other fruits and vegetables. The others will get chocolate without the active flavonoids.
“This could help doctors give advice to patients on the type and amount of foods to eat to reduce heart disease risk—and it does not necessarily need to be chocolate,” Cassidy said. “If this trial works we will be able to advise on a whole range of foods. People won't have to go around eating specially designed chocolate.”

Elizabeth Mitchell’s new “Liberty’s Torch” is the fascinating story of how the Statue of Liberty came to be. The Statue of Liberty’s rough history is explored in “Liberty’s Torch”.
Frederic Auguste Bartholdi is an all-but-forgotten figure in American history. He was, however, responsible for one of the most enduring symbols of the United States: the Statue of Liberty. A Frenchman from Alsace, he designed and built the Statue of Liberty which stood on Bedloe’s Island in New York Harbor. How this statue came to be is the fascinating subject of Elizabeth Michell’s new book “Liberty’s Torch”.
The power of Mitchell’s narrative is convincing(令人信服的). We recognize the Statue of Liberty now as a symbol of hope and opportunity for a nation of immigrants. At the time, though, people could not see that－nor did they even imagine that. Instead, the construction of the statue was born of one man’s desire to set up a great monument.
For this reason, perhaps, “Liberty’s Torch” relies on Bartholdi as the connecting thread. Bartholdi went to Egypt to make photographic copies of the main monuments. On the boat, Bartholdi met and began a lifelong relationship with Ferdinand de Lesseps, the man who would build the Suez Canal. Maybe it was this friendship, or maybe it was seeing Egypt’s huge monuments, but finally the trip inspired Bartholdi’s dream to create the largest statue ever built. Failure to bring this to completion in Egypt, followed by his exile (流放) from Paris, led Bartholdi to sail to America.
By explaining the Statue of Liberty’s hard history and showing Bartholdi’s brave spirit, Mitchell has done a great service. It can be inferred from the text that ________.
| A．American people have never forgotten Frederic August Bartholdi |
| B．the Statue of Liberty wasn’t originally regarded as a symbol of hope |
| C．Bartholdi finished the Suez Canal |
| D．Bartholdi was a famous architect from Egypt. |
What was the main reason for Bartholdi to build the Statue of Liberty?
| A．To finish his education in the arts. |
| B．To mark his friendship with Ferdinand. |
| C．To create something better than Egyptian monuments. |
| D．To achieve his dream to create the largest statue. |
What type of writing is the passage?
| A．A travel guide. | B．A book review |
| C．An announcement | D．An architecture report. |
Hello. I’m Jan from Mrs. Lake’s class. My class wants to work together to help the public. We think we have found a great way to do this. Last month we did a class project on the highways near our town. We learned about the Adopt-a-Highway Program. This program brings people together to pick up litter along the roads. We think it would be a great idea for all students in our school to join the program and adopt a highway.
Adopting a highway is not like adopting a pet. When a highway is adopted, only part of the highway is cared for by a group of people. The group agrees to work every week to keep its part of the highway clean. Each group gets its own sign that has the name of the group printed on it. The sign is put up at the side of the road. This sign lets drivers know who is keeping that area of the road clean.
The Adopt-a-Highway Program is a great way for people to help their environment look nicer. Also, the government does not have to send out as many road workers. This saves money. Finally, people may try harder to keep roads clean if they see people, especially teenagers like us, cleaning them up.
We will need helpers to care for our adopted highway. If you want to feel great and keep our roads clean，please come with your parents to the meeting next week. We will meet in Mrs. Lake’ room on Wednesday at 6:00 P.M. At the meeting, we will talk about which roads are the dirtiest as a result of people's unkind acts. Then we' ll
try to pick an area to adopt and clean.
I look forward to seeing you at the meeting. Remember to keep our roads clean!What is the Adopt-a-Highway Program about?
| A．Giving names to the highways. |
| B．Drawing pictures of highways. |
| C．Picking up litter along the roads. |
| D．Putting up signs near the roads. |
What should the students do first if they want to join the program?
| A．Pick a spot to care for. |
| B．Call Mrs. Lake next week. |
| C．Write a letter to their parents. |
| D．Go to a meeting on Wednesday. |
What is the purpose of this speech?
| A．To encourage students to join the program. |
| B．To introduce the traffic system. |
| C．To show drivers how to drive safely. |
| D．To tell a story about adopting a pet. |
Which of the following can be the best title for the passage?
| A．Adopt-a-Pet |
| B．Adopt-a-Highway |
| C．Ways to Protect the Environment |
| D．Volunteers on Roads |

Shyness is the cause of much unhappiness for a great many people. Shy people are anxious and self-conscious; that is, they are concerned with their own appearance and actions too much. Negative thoughts are constantly occurring in their minds: What kind of impression am I making? Do they like me? Do I sound stupid? Am I wearing unattractive clothes?
It is obvious that such uncomfortable feelings must affect people unfavorably. A person's self-concept is reflected in the way he or she behaves and the way a person behaves affects other people's reactions. In general, the way people think about themselves has a deep effect on all areas of their lives.
Shy people, who have low respect, are likely to be passive and easily influenced by others. They need faith that they are doing "the right thing". Shy people are very sensitive to criticism. It makes them feel inferior（自卑）.They also find it difficult to be pleased by praises because they believe they are unworthy of praise. A shy person may respond to a praise with a statement like this one: "You're just saying that to make me feel good, I know it's not true.” It is clear that, while self-awareness is a healthy quality, overdoing it is harmful.
Can shyness be completely got rid of, or at least reduced? Fortunately, people can overcome shyness with determination since shyness goes hand in hand with lack of self respect. It is important for people to accept their weakness as well as their strengths. Each one of us has his or her own characteristics. We are interested in our own personal ways. The better we understand ourselves, the easier it becomes to live up to our chances for a rich and successful life.The first paragraph is mainly about______.

| D．have nothing to do with lack of self respect |
Roughly half of college students will have some degree of depression at some point during their time in school. Even more startling, 6.2 percent of college students surveyed in 2012 considered suicide and 1.3 percent attempted it, according to an American College Health Association study released this spring. If you’re feeling depressed on campus, you may find the following tips helpful.
Exercise: Physical activity releases endorphins – chemicals that produce an overall positive feeling within the body, which fight depression naturally. Mental health experts claim that exercise is a solution to those feeling mild or moderate depression. However, for those severely depressed, simply doing sports is not enough.
Use school counseling services: Campuses don’t employ mental health experts simply to throw thousands of dollars down the drain. Their job is to help students, so experts recommend you use them. Most students, however, are hesitant to take a trip to their college’s counseling center, fearing being laughed at by peers. As a result, some schools like Texas Christian University, are testing students for mental health problems when they get sick and visit the campus health clinic.
Take advantage of technology: Staying in touch with family members and friends from childhood and high school has become easier than ever with the coming of Facebook and video chat services like Skype. While mental health experts insist that it’s important to make friends in your new environment and be involved in the college community, it’s also significant to keep in touch with the people you knew before college.
Go to sleep: Following a fairly regular sleep pattern can defend you against depression. In college, many students’ sleep patterns are irregular thanks to late-night studying and partying, which is harmful to their mental health. Research strongly suggests that sleep is the key to learning and memory formation.According to the passage, physical activity __________ .
| A．is regarded as the best way to fight depression |
| B．contributes to the release of endorphins |
| C．can’t help the seriously depressed students |
| D．improve people’s ability to learn and memorize |
It can be inferred from the 3rd paragraph that __________ .
| A．employing mental health experts on campus is a waste of money |
| B．students with mental health problems can’t get on well with others |
| C．going to college’s counseling center for help requires a lot of courage |
| D．sick students in Texas Christian University must take psychological tests |
Taking advantage of technology is encouraged because it ____
| A．enables students to get involved in college life |
| B．helps students stay in contact with others |
| C．offers students a way to make new friends |
| D．provides a way to avoid getting bored |
which of the following can NOT help one reduce depression?
| A．Taking exercise regularly every week |
| B．Chatting with old friends with Skype |
| C．Turning to mental health experts for advice |
| D．Holding parties deep into the night to relax |
