No one would much like the idea of eating 61 pounds of tomatoes a day. But if their goodness was put into an easy-to-swallow pill that you were told might prevent strokes(中风) and heart attacks you would probably be putting in an order tomorrow.
Researchers believe they may have come up with just that after trials. The daily pill contains a chemical called lycopene (番茄红素) which makes tomatoes red and is known to break down fat in the vessels(血管). A Cambridge University study found taking the pills improved blood flow and the lining of vessels in patients with pre-existing heart conditions. It also increased the flexibility(灵活性) of their vessels by 50 percent. The scientists believe it could limit the damage caused by heart disease-responsible for 180,000 deaths a year, and help cut the 49,000 deaths a year from strokes. They also hope it could benefit those with arthritis(关节炎), diabetes(糖尿病) and even slow the progress of cancer.
Each pill is equal to eating around 61 pounds of ripe tomatoes. Studies have shown eating a Mediterranean-style diet rich in tomatoes fish, vegetables, nuts and olive oil can significantly reduce cholesterol(胆固醇) and help prevent cardiovascular disease.
Preliminary (预先的) results from a two-month trial, in which the pill was given to 36 heart disease patients and 36 healthy volunteers with an average age of 67, were presented at a meeting of the American Heart Association. It was shown to improve the function of the layer of cells lining blood vessels. It also improved their sensitivity to nitric oxide(氧化氮), the gas which causes the enlargement of the vessels in response to exercise.
Ian Wilkinson, head of Cambridge University’s clinical trials unit, said “These results are potentially very significant and it meets the goal, but we need more trials to see if they translate into fewer heart attacks and strokes.”
Further studies are planned, with researchers hoping it could offer a choice for heart disease sufferers who can not take the cholesterol-lowing drugs.
Mike Knapton, head of the British Heart Foundation, said, “Although this showed lycopene improved blood flow in people with heart disease, that’s a long way from demonstrating that taking it could improve outcomes for people with heart disease. The best way to get the benefits of a good diet is to eat plenty of fresh fruit and vegetables.”
1.What can we infer from Paragraph 1?
A. We can eat too much tomato food.
B. Tomatoes are helpful to strokes and heart attacks.
C. Tomatoes will lose healthy elements when were put into pills.
D. We had better not eat tomatoes.
2.We can learn from the passage that the pills ____.

Like many new graduates, I left university full of hope for the future but with no real idea of what I wanted to do. My degree, with honors, in English literature had not really prepared me for anything practical. I knew I wanted to make a difference in the world somehow, but I had no idea how to do that. That’s when I learned about the Lighthouse Project.
I started my journey as a Lighthouse Project volunteer by reading as much as I could about the experiences of previous volunteers. I knew it would be a lot of hard work, and that I would be away from my family and friends for a very long time. In short, I did not take my decision to apply for the Lighthouse Project lightly. Neither did my family.
Eventually, however, I won the support of my family, and I sent in all the paperwork needed for the application. After countless interviews and presentations, I managed to stand out among the candidates(候选人) and survive the test alone. Several months later, I finally received a call asking me to report for the duty. I would be going to a small village near Abuja, Nigeria. Where? What? Nigeria? I had no idea. But I was about to find out.
After completing my training, I was sent to the village that was small and desperately in need of proper accommodation. Though the local villagers were poor, they offered their homes, hearts, and food as if I were their own family. I was asked to lead a small team of local people in building a new schoolhouse. For the next year or so, I taught in that same schoolhouse. But I sometimes think I learned more from my students than they did from me.
Sometime during that period, I realized that all those things that had seemed so strange or unusual to me no longer did, though I did not get anywhere with the local language, and returned to the United States a different man. The Lighthouse Project had changed my life forever.

3.In his application for the volunteer job, the author____.
A. went through challenging survival tests
B. participated in many interviews
C. wrote quite a few papers on voluntary work
D. faced strong competition from other candidates
4.What can we infer from the author’s experiences in Nigeria?
A. He had learned to communicate in the local language.
B. He found some difficulty adapting to the local culture.
C. He had overcome all his weaknesses before he left for home.
D. He was chosen as the most respectable teacher by his students.

Controlling your food longings and dropping pounds fast is easy: Just eat breakfast. The editors of Eat This, Not That! carried out researches to determine some best breakfast food for weight loss.
Black Beans
Protein, per 1/2 cup: 7g
Black beans will not only fill you up for hours but also help slim you down. Wake Forest Baptist Medical Center researchers found that with black beans consumed daily, study participants’ fat reduced by 4 percent over two years.
Peanut Butter
Protein, per 2 tbsp: 7—8g
While processed peanut butter is filled with sugar and oils, the real stuff is made with just two ingredients: salt and peanuts. The peanut is filled with heart-healthy monounsaturated fats. Nutritionist and personal trainer Kristin Reisinger suggests using the healthy fat in an AM smoothie.
Almond Butter
Protein, per 2 tbsp: 7—8g
“Almond butter is high in protein, fiber and monounsaturated fats,” says Martha McKittrick, RDN, CDE. “Studies have also shown that people who eat nuts are less likely to become overweight than those who avoid them, likely because it helps you feel fuller.” To get the benefits at breakfast, McKittrick suggests spreading some nut butter on the whole grain toast.
Eggs
Protein, per two large eggs: 13g
“Eggs are an excellent source of protein and other healthy nutrients including fat-burning choline(胆碱),” says McKittrick. Choline, also found in lean meats, seafood and collard greens, attacks the gene mechanism that causes your body to store fat around your liver, according to Zero Belly Cookbook. The more eggs you eat, the less egg-shaped you get.
1.Which two foods contain the same amount of protein?
A. Black beans and eggs
B. Almond butter and eggs
C. Black beans and peanut butter
D. Peanut butter and almond butter
2.How does Almond Butter help control weight?
A. It helps people sleep better B. It offers people more protein
C. It makes people feel fuller D. It makes people burn more calories

Would you jump off the Great Wall of China for 300 pounds a day?
A stunt (特技表演)person is a man or woman who does all the dangerous bits of acting work in films or on TV. This can be anything from a simple fall into a swimming pool, or walking off the top of a tall building. It sounds like a job that you would have to be made to try, but there are actually lots of people who want to do it.
Sarah France, twenty-four, is one of Britain’s sixteen professional stunt women ---there are one hundred and sixty stunt men in the country. We asked Sarah how she came to be a stunt woman.
“When I was young I was trained to be a dancer, and for seven years after school I was hardly out of work. A dancer’s life is pretty short, though, and my father suggested I should think about doing stunt work after I’d given up dancing. I thought about it for the next two years and decided to have a go. For six months, I worked really hard every day. I had to learn different skills---swimming, jumping, horse -riding, etc.”
Sarah finished the course in just five months and applied to the office which decides whether you’re accepted as a professional stunt person or not. Two weeks after she was accepted, Sarah was throwing off the Great Wall of China in Superman IV.
“I was very lucky to get work so quickly. I had a small part, playing a traveler who fell off the Wall after an earthquake. The traveler’s life was saved by Superman, of course! Actually, I fell forty-five feet into a pile of cardboard boxes! You can’t use anything softer than that or you will be brought back into view of the cinema. Instead you just have to learn to fall properly. It’s quite dangerous but I enjoy it.”

A. they are mad B. they don’t think them dangerous

4.Which of the following words best describes Sarah?

Nicolai Calabria has already become one of the best 106-pound wrestlers. He has successfully climbed to the top of the highest mountain in Africa, and most importantly, he's changed the attitude of any normal person who watches him compete.
The 17-year-old teenager has one leg. He was born that way, but his goal is to show it's not the one thing that defines him. He would also be the first one to tell you that he just wants to prove to others and himself that he's just like other normal ones.
When Calabria was young, his parents tried different prostheses(假肢)to find out which was most comfortable for their son as he tried to keep up with a family, who has a preference for sports.
At first, the Calabrias had their middle child in a prosthesis that looked and functioned like a “real” leg, but soon they decided to choose a different path when they found it wasn't beneficial to his movement. Then the family moved him to arm crutches(手杖) and from there a new burst of energy was found.
Getting others to believe that he could take off on the soccer field took a little bit longer. When the Calabrias moved to Concord, they had a hard time convincing the town soccer program to allow a child like him to compete with able-bodied kids. After months and months of debates and meetings, the family received the answer they were looking for. Since then, witnessing a young man on crutches who competes against those with two legs has become a fixed event in the Concord community.
“At that time I had nothing but discouragement working with the soccer community, however, now I have nothing but admiration for the fact that he's been allowed to play, and people see that he adds value to game,” his father said, “I just think it's a great result.”
1.This passage shows us a boy with one leg ________.
A. can do what a normal teenager can
B. is realizing as many dreams as he can
C. can make a sport event more valuable
D. can add value to society
2.We can learn from Paragraph 5 that ________.
A. Calabria proved to be the most excellent player of the team
B. it was not easy for Calabria to be accepted to the town's soccer team
C. Calabria's parents didn't allow him to play soccer at first
D. there are some other disabled children in the soccer team
3.In Paragraph 5, the underlined part “a fixed event” probably means “________”.
A. a must-see
B. a planned program
C. an extra game
D. a special occasion
4.It is implied in the last paragraph that Nicolai's father ________.
A. has been discouraged since Nicolai played soccer
B. thinks that Nicolai is playing a key role in the team
C. is very delighted that Nicolai can play soccer in the team
D. hasn't expected that Nicolai can be allowed to play soccer
