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.”

The month of May is not only a graduation month in the US, but also a month when some families hold reunions．Have you ever considered why it is important that families get together in one place for a particular time? I believe the reason is honor．
Family reunions are a time we can take out of our busy schedules and spend quality time with our extended families（大家庭）．It is a time when we can make our sisters, brothers, aunts, uncles, grandparents, and others we love a priority （首要事情）in our life．
Some reunions take place over a picnic lunch and some last a whole weekend．They can be costly and are sometimes crazy．But the truth is, when people you love grow up and move away, getting together for a family reunion and holding that family bond together is so important．
Family reunions build a renewed closeness as we mix with our relatives．We sit and talk about old times and listen to the stories that our older and wiser relatives love to share．As the children run and play and get to know each other, we sit and revisit our childhood memories and enjoy the short time we have together．
The best part of a family reunion is the time spent simply being around the people you care about A reunion shows how important it is to take time for each other．When you receive a family reunion invitation, make it a priority in your life．It's a great chance to see your relatives once again, give them a big hug and enjoy the time you have with them．Life is too short not to!What would be the best title for the passage?

Teenagers who do not get enough of the nutrients commonly found in fruits and fish are easier to have bad lungs, coughing and wheezing （喘息）．Teens who eat the least of fruit and especially vitamin C have weaker lungs compared to the others．
Teens who take in less vitamin E, found in vegetable oil and nuts, are more likely to have asthma（哮喘）, Jane Bums at the Harvard School of Public Health found.
Based on these findings．Bums said that current recommended dose（一剂）of vitamin C, 85 mg a day, may not be enough for teens to have healthy lungs．Teens who eat less fruit and don't take in enough fatty acids （脂肪酸） are more likely to have asthma and the signs of breathing difficulty．
Proper amounts of fatty acids are protective, Bums said, though fish, the best source of fatty acids, is particularly unpopular with teenagers．Fatty acids are also found in some nuts as well as some green vegetables'．Smokers who avoid vitamin C will increase their chances of coughing, wheezing and developing phlegm（痰）．
More than 80 percent of teens are getting their recommended doses of vitamin C - mainly from fruit drinks．"I wouldn't approve of drinking them, but at least they're getting their vitamin C from somewhere," Burns said．
Burns added that there are several different ways to get the necessary nutrients．"I think vitamin supplements are fine．I think adding vitamin D to orange juice is fine．But I do think there are added benefits that we don't fully understand of eating whole foods like fruits and vegetables and fish," she said．The researchers did not account for poverty and other factors that often distinguish less-healthy eaters and may explain their findings．According to the passage, what is the problem with teens who don't get enough nutrients?

"Hey, Dad," one of my kids asked the other day, "what was your favourite fast food when you were growing up?"
"We didn't have fast food when I was growing up," I informed him．"All the food was slow．" "Where did you eat?" "It was a place called 'at home'．" I explained．"Grandma cooked every day and when Grandpa got home from work, we sat down together at the dining table, and if I didn't like what she put on my plate I was allowed to sit there until I liked it．"
Some parents never owned their own houses, set foot on a golf course, travelled out of the country or had a credit card．
My parents have never driven me to soccer practice．This was mostly because we never had heard of soccer．I had a bicycle that weighed probably 50 pounds, and only had one speed．We didn't have a television in our house until I was 11．I was 13 when I tasted my first pizza; it was called "pizza pie"．When I bit into it, I burned the roof of my mouth and the cheese slid off, swung down, plastered（粘贴）itself against my chin and burned that, too．It's still the best pizza I ever had．
I delivered newspapers, six days a week ．The paper cost 7 cents, of which I got to keep 2 cents．I had to get up at 4:00 a．m．every morning．On Saturday, I had to collect the 42 cents from my customers．My favourite customers were the ones who gave me 50 cents and told me to keep the change．

As the new term starts, freshmen around the world are asking the same question: how can I make the best of four years at college? The New York Times received suggestions recently from PhD students and seniors at some of the top universities . Here is their advice.
“Many young people today are raised in a protective cocoon(茧)”, wrote Tim Novikoff, a PhD student at Comell. “College is a time to explore the world beyond and a chance to learn new things about yourself. Take classes in different subjects. Try lots of different clubs and activities.”
Remember also to take some time away from campus, suggested Willie Lin, a student at Washington University. “If you spend all of your time in school, then it becomes too easy to let criticism from an unkind professor or a conflict with a roommate take up large proportions.”
Try to find work assisting a researcher or a professor---this is the advice from Aman Singh Gill, a PhD student at Stony Brook University. And he also said, “With a window into the world of research, you will find yourself thinking more critically, accepting fewer states at face value and perhaps developing a brave sense of what you can accomplish.”
Many young people can’t imagine even a single day without devices such as computers and cell phones. But try to keep yourself off them, cautioned Christine Smallwood, a PhD student at Columbia University.
Start by scheduling a few Internet-free hours each day, with your phone turned off. It’s the only way you’ll be able to read anything serious. “This will also have the benefit of making you harder to reach, and thus more mysterious and fascinating to new friends and acquaintances(熟人),” she suggested.The underlined sentence in Paragraph 3 means we should _________.
| A．spend more time at school | B．take some time out of school |
| C．listen to criticism more | D．not argue with roommates |
Who thinks it is important to consider something critically?
| A．Aman Singh Gill | B．Christine Smallwood |
| C．Tim Novikoff | D．Willlie Lin |
As for modern information devices, the last two paragraphs mean to tell us ________.
| A．to keep ourselves off them forever not to use them |
| B．to turn them off |
| C．to make a schedule to use them |
| D．not to use them |
This passage is mainly about _________.
| A．tips from some students for college life |
| B．ways to read something serious regularly |
| C．days without cell-phones and computers |
| D．chances to go to university you really like |
