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.”

2. What’s the purpose of the trial?

3. From Paragraph 3 we can infer that __________.
A. Cassidy’s team has done several studies on chocolate
B. dark chocolate has proved beneficial to health
C. people should eat much chocolate with high sugar and fat
D. most commercially available chocolate doesn’t contain flavonoids
4. Which of the following statements is TRUE according to the passage?

Ed Jocelyn and Andy McEwen might have appeared to be a bit mad---the two set off on their own “Long March” through the remotest regions of China on October 16. The idea was to take a year to retrace one of the epic movements of modern military history.
The two British men in their mid-30s were working as editors in Beijing when they decided to reexperience the tales of the original marches. “We hold these people in such respect,” McEwen says.
They plan to keep diaries but will not share the contents during the trip. “When we get to the end we’ll put our heads together and try and come up with a book,” Jocelyn said.
Their trip has had some auspicious beginning, they have already met two Long March veterans(老战士) in less than a month of travel.
In this modern version, the pair are aided by high-tech equipment including a satellite phone, mini-computer, video camera and solar panels to recharge batteries. A mountain tent and portable stove will help them in the remoter stretches.
They plan to average 35-40 kilometers a day, and rest about every third day. Ed admitted that their trip would be very tough.
If they succeed, they will be the first foreigners to complete the entire Long March route since Otto Braun, the German military advisor who accompanied the Red Army on the Long March.
This text is mainly about .
A．high-tech equipment helpful to the Long March
B．first foreigners to walk the Long March
C．British recall of the Long March spirit
D．British editors’ adventure original in China
The underlined word “auspicious” most probably means .
A．friendly B．favourable C．strange D．surprising
Which of the following statements is NOT true about the two foreigners?
A．They will use anything modern on the way.
B．They will do some cooking by themselves.
C．They’re planning to have a book published one year later.
D．They will send off news about what happens day by day.

In our life, we have rarely expressed our gratitude to the one who lived those years with us. In fact, we don't have to wait for anniversaries to thank the ones closest to us and the ones so easily overlooked. If I have learned anything about giving thanks, it is this: give it now! While your feeling of appreciation is alive and sincere, act on it. Saying thanks is such an easy way to add to the world's happiness.
Saying thanks not only brightens someone else's world, it brightens yours. If you're feeling left out, unloved or unappreciated, try reaching out to others. It may be just the medicine you need. Of course, there are times when you can't express gratitude immediately. In that case, don't let embarrassment sink you into silence and speak up the first time you have the chance.
Once a young minister, Mark Brian, was sent to a remote parish(教区)of Kwakiutl Indians in British Columbia. The Indians, he had been told, did not have a word for thank you. But Brian soon found that these people had unusual generosity. Instead of saying thanks, it is their custom to return every favor with a favor of their own, and every kindness with an equal or superior kindness. They do their thanks. I wonder if we had no words in our vocabulary for thank you, would we do a better job of communicating our gratitude? Would we be more responsive, more sensitive, more caring?
Thankfulness sets in motion a chain reaction that transforms people all around us－including ourselves. For no one ever misunderstands the melody(旋律)of a grateful heart. Its message is universal; its poems transcend(超越)all earthly barriers; its music touches the heaven.
【小题1】Who do we easily forget to express our thanks to according to the writer?
| A．Friends not meeting for a long time. | B．Former teachers and friends. |
| C．People we want to get close to. | D．Our family members and good friends. |
| A．benefits the people who do something for us |
| B．is good for both us and people who help us |
| C．wastes our and our friends' time at the same time |
| D．does harm to both us and people who help us |
| A．The only way to thank others is to express by your own words. |
| B．The best way to thank others is to do something for them. |
| C．We can thank people who help us in various ways. |
| D．We can thank people who help us in two ways. |
| A．to help and appreciate others | B．to ask others to help us |
| C．to remind others of our helping them | D．to ask someone to help others |
