On Monday, the Centers for Disease Control and Prevention predicted that 42% of Americans could be overweight by 2030. Our expanding waistlines lead to not only a medical problem, but according to a recent article in The New York Times, it could also endanger personal situations 一 in an airplane crash, for example.
The New York Times’ Christine Negroni reports that engineers and scientists are questioning whether airplane seats are adequately constructed to protect overweight travelers. Government standards for airplane seat strength (强度）first set more than 60 years ago一 require that the seats be made for a passenger weighing 170 pounds (77kg). Today, the average American man weighs nearly 194 pounds (88 kg) and the average woman 165 pounds (75 kg). Negroni reports:
“If a heavier person completely fills a seat, the seat is not likely to behave as intended during a crash,” said Robert Salzar, the leading scientist at the Center for Applied Biomechanics at the University of Virginia. “The energy absorption that is built into the aircraft seat is likely to be overpowered and the passengers will not be protected properly. "
“Nor would the injury be limited to that passenger only,” Dr. Salzar said “ If a seat or a seat belt fails,” he said, “those people who are seated nearby could be endangered by ‘ the uncontrolled movements of the passenger’.”
Most complaints about airplane seats focus on their lack of comfort and high ticket price and whether overweight passengers should be made to buy two seats. But The New York Times’ article brings up another reason to feel anxious about flying. Investigators of the issue got in touch with the airplane seat and seat belt makers, but they refused to comment on the problem. Experts agreed that crash testing should be done with overweight dummies (人体模型). Both airplane seats and seat belts should be tested, they said.
Fortunately, however, according to Nora Marshall, a senior adviser at the National Transportation Safety Board, the board’s investigators have never seen an accident involving a commercial plane in which the weight of a passenger is a problem.
1.What is the article in The New York Times mainly concerned with?
A. The size of airplane seats and seat belts.
B. Safety of overweight airplane passengers.
C. Airplane crashes involving commercial planes.
D. A medical problem caused by being overweight.
2.Robert Salzar would probably agree that ______ .
A. overweight passengers should buy two seats
B. the government should help produce bigger planes
C. standards for airplane seat strength should be raised
D. passengers should know how to protect themselves
3.We can learn from the text that ______ .
A. airplane seat makers have taken action now
B. there are few complaints about airplane seats
C. those seated near the overweight may suffer too
D. only a small number of airplane accidents involve the overweight
4.What is the best title for the text?
A. Why do passengers feel anxious about flying?
B. Will 42% of Americans be overweight by 2030?
C. When will the overweight enjoy their flight?
D. Are airplane seats safe enough for the overweight?

On Monday, the Centers for Disease Control and Prevention predicted that 42% of Americans could be overweight by 2030. Our expanding bodies not only lead to a medical problem, but also endanger personal safety in some situations—in an airplane crash, for example, according to a recent article in The New York Times.
The New York Times’ Christine Negroni reports that engineers and scientists are questioning whether airplane seats are designed to protect overweight travelers. Government standards(标准) for airplane seat strength—first set more than 60 years ago---require that the seats be made for a passenger weighing 170 pounds. Today, the average American man weighs nearly 194 pounds and the average woman 165 pounds. Negroni reports:

The Centers for Disease Control and Prevention (CDC) recently announced trends in fruit and vegetable consumption(食用) among adults. Since 2000, the CDC has made efforts with goals of getting 75% of Americans to eat two or more servings of fruit a day and 50% of Americans to eat three or more servings of vegetables a day. Unfortunately, Americans aren’t meeting these modest targets.
Although a diet high in fruit and vegetables can reduce the risk of many diseases, Americans just aren’t getting enough. In fact, since 2000, the amount of vegetables Americans are eating has stayed the same and the amount of fruit Americans are eating has gone down. The CDC also finds that only about a third of adults are eating their expected servings of fruit, and just over a quarter of adults are eating their expected servings of vegetables.
So why aren’t Americans getting their expected servings of fruit and vegetables? It turns out that Americans might be spoiled when it comes to their produce. A national survey conducted by Fruit2day reveals that nearly half of Americans leave fruit in their fridges until it rots with people in Boston among the worst and those in New York and Los Angeles among the best. Sadly, most Americans admit to leaving fruit in the fridge for more than a week.
There are many reasons why Americans don’t eat their fruit or vegetables, including the inconvenience of having to wash or peel it. Fruit2day offers consumers a surprising and convenient way to enjoy the goodness of fruit.
“With no added sugar, natural juices and two full servings of fruit, our Fruit2day line has really captured the imaginations of health-conscious consumers who are actively looking to get more fruit in their diets,” said Hanno Holm, president and chief executive officer of Hero-White Wave. “Fruit2day makes getting more fruit in one’s diet easier for any daily snack routine.”
1.For 4 million American adults, how many of them are eating two or more servings of fruit a day?
A．About 1.3 million. B．About 2 million. C．About 3 million. D．About 1 million.
2.We can learn from the first two paragraphs that __________ .
A．Americans have been eating fewer vegetables since 2000.
B．most Americans eat less fruit to reduce the risk of diseases.
C．most Americans prefer fruit to vegetables.
D．over 25% of adults are eating three or more daily servings of vegetables.
3.In which city are people most likely to leave fruit in their fridge?
A．In Boston. B．In New York. C．In Los Angeles. D．Not mentioned.
4.With the help of Fruit2day, Americans can __________ .
A．easily get rid of their bad eating habits
B．conveniently have more fruit in their diets
C．add sugar and natural juices to their diets
D．find another excuse for not eating healthily
5.Americans don’t eat their fruit or vegetables because __________ .
A．they are relatively forgetful
B．they are too busy with their work
C．they don’t think it convenient to eat them
D．they prefer daily snacks with added sugar

Did you get a flu shot this year? For the first time, the Centers for Disease Control and Prevention in the US is recommending that all children ages 6 months through 18 years receive the flu vaccine.
Vaccines battle diseases caused by bacteria and viruses. A weakened form of the germ is introduced into the body. The body makes special substances called antibodies to fight the germs. If the actual germs were to attack, the antibodies would fight them.
Because there are many kinds of flu viruses, scientists must create a new vaccine formula (配方) each year. Researchers must make a prediction.
“The flu vaccine is not as effective as the polio (小儿麻痹症) vaccine or the measles(麻疹) vaccine,” says Dr. William Schaffner of Vanderbilt University School of Medicine.
“It’s not a great vaccine, but it is quite a good vaccine.”
But a flu vaccine doesn’t work for everyone. There are certain people who should be careful about taking it. Because the vaccine is produced from eggs, those who are allergic (过敏的) to eggs should not take it. If you have a fever, you should wait until you recover.
Some people are afraid that they might get the flu from the flu shot. Scientist say that it is not possible, because the viruses in the flu shot are inactivated (灭活的). But some minor side effects such as low-grade fever and body aches could occur. If they do, they begin soon after the shot and usually last only one to two days.
1.What is an antibody?
A. An antibody is a vaccine formula
B. An antibody is a germ that is introduced into the body
C. An antibody is a vaccine that fights diseases.
D. An antibody is a special substance to fight germs.
2.Which of the following statements is NOT true?
A. Not everyone is suitable for the flu vaccine.
B. The flu vaccine is not so effective as the measles vaccine
C. Flu viruses create new vaccine formulas each year.
D. People can’t take the flu vaccine at anytime.
3.It can be inferred from the text that _____.
A. scientists should change the vaccine formula each year
B. vaccines can battle diseases caused by bacteria and viruses
C. all children ages 6 months through 18 years can receive the flu vaccine
D. scientists are responsible for the side effects of the flu vaccine
4.Which of the following would be the best title for the text?
A. The flu vaccine B. Side effects of the flu vaccine
C. How to prevent the flu D. Not everyone can get the flu shot

Stressed About Coronavirus? Monitor Your Body Language
The Centers for Disease Control and Prevention (CDC), and other health professionals, have maintained that the recent coronavirus can be spread by touching people or surfaces infected by the virus, and then touching your face-particularly your mouth, nose, and eyes, where the virus can gain access to your body. No doubt, fears of this potentially deadly virus is causing people around the world a great deal of stress. 1.
You may have seen clips of health professionals warning about face-touching in press conferences, but then absent-mindedly touching their own faces-even licking a finger to turn a page on their written speeches! 2. Unfortunately, stress can increase the incidence of face-touching behavior.
A common body reaction to stress is self-touching. Some of that might consist of chin or cheek rubbing, which can bring infected fingers dangerously close to the mouth. Of course, there is also nail-biting, which provides the virus with direct access to the mouth.
Research on nonverbal signals of lying has focused on common body language signals connected with stress. 3. Stress from telling a lie has been associated with people touching their noses or faces. It has been suggested that temporary increases in tension or stress-such as when someone is telling a lie-may cause the nose to itch (发痒). This leads to response of scratching or rubbing the nose
Stress may also lead to dry eyes, mainly because the automatic reaction to fear-induced stress is to widen the eyes and blink less frequently, thus drying out our eyes. Our responses can include eye rubbing behavior-opening the way for the virus to enter our bodies.
Don’t get me started talking about greetings. 4. However, greeting behaviors such as touching hands (handshaking), cheek-kissing and hugging all open the door for viral transmission (病毒传播). Moving to more safe forms of greeting -waves, fist-bumps, or even bowing-should become the norm during these troubling times.
5. We need to become more aware of our nonverbal behavior and go into social situations more mindfully.
A.To sum up, what should we do?
B.Some of these same signals could lead to infection.
C.It is probably because they have been under too much stress.
D.In other words, nonverbal signals of stress might lead to infection.
E.That is why people may touch their noses or faces when telling a lie.
F.In social gatherings people almost automatically extend their hands or hug.
G.What’s worse many of our unconscious reactions to stress can lead to infection.

After shopping for deals in stores on “Black Friday”, or online on “Cyber Monday”, Americans and people worldwide are preparing for newly popular “Giving Tuesday”. Starting in 2012, now the global event that is celebrated annually on the Tuesday after Thanksgiving is the brainchild of 92nd Street Y, a cultural center in New York City and the United Nations Foundation.
As the name indicates, “Giving Tuesday” is meant to restart the charitable season and therefore observed by raising funds for local nonprofits and schools, organizing food and clothing drives, and conducting random acts of kindness. In 2015, 700,000 people from 71 countries came together to donate $116.7 million in cash. An additional $1.08 million was spent on gifts.
While the easiest way to participate is by donating to your favorite charity, this day can be celebrated in many other ways too. You can give back by volunteering at your local shelter or food bank, or even by donating blood. If all else fails, a purchase from the growing number of organizations that give a portion of their sales to charity will do the trick.
But perhaps the best way to celebrate the day is by helping those nearest and dearest to you. Assist a family member with a simple chore like folding laundry, cooking dinner, or even reading to a younger sibling. No matter what you do, be sure to share your good deed on social media and inspire others to celebrate “Giving Tuesday” as well!
1.What’s the main purpose of “Giving Tuesday”?
A.To persuade more people to shop online.
B.To make Thanksgiving Day enjoyable.
C.To encourage more people to do charity.
D.To get voluntary work better known.
2.Why does the author advise sharing good deeds on social media?
A.To donate money to local schools.
B.To keep a record of one’s experience.
C.To help people make new friends.
D.To make “Giving Tuesday” more popular.
3.Which section of a website does the text probably come from?
A.Business. B.Culture. C.Education. D.Lifestyle.

Health experts are calling for action to increase cancer care and control in the developing world. A medical research paper says cancer was once thought of as a problem mostly in the developed world. But now cancer is a leading cause of death and disability in poor countries as well. Experts from Harvard University and other organizations urge the international community to fight cancer actively, saying it should be fought in the way HIV/AIDS has been fought in Africa.
Cancer kills more than 7.5 million people a year worldwide. Almost two-thirds are in low-income and middle-income countries.
They discover cancer kills more people in developing countries than AIDS, tuberculosis (肺结核) and malaria (疟疾) combined. But the world spends only 5% of its cancer resources in those countries.
Felicia Knaul from Harvard Medical School was one of the writers of the paper. She was in Mexico when she was found to have breast cancer. She received treatment there and her experience showed her the sharp difference between the rich and the poor in treating breast cancer.
Felicia Knaul says, “And we are seeing how this is attacking young women. It’s the number two cause of death in Mexico for women thirty to fifty-four. All over the developing world, it’s the number one cancer-related death among young women. I think we have to again say that there is much more we could do about it than we are doing about it.”
Professor Knalul met community health workers during her work in developing countries. They were an important part of efforts to reduce deaths from the cancer. They were able to persuade people to get tested to prevent the illness. The experts say cancer care does not have to be costly. For example, patients can be treated with lower-cost drugs.
1.What would be the best title for the passage?
A. Cancer – a leading cause of death in poor countries
B. What should we do in preventing and treating cancer?
C. What makes the first killer in developing countries?
D. Experts urge more efforts to fight cancer.
2.Felicia Knaul’s experience in Mexico shows that ________.
A. many Mexican women suffer from breast cancer
B. there is not enough medicine for cancer there
C. many Mexican women can’t afford medical care
D. patients with breast cancer are treated differently
3.From what Felicia Knaul says, we can draw the conclusion that ________.
A. breast cancer is a great threat to young women
B. people don’t pay enough attention to breast cancer
C. breast cancer is the second killer among women in Mexico
D. patients can be treated effectively in developing countries
4.Who plays an important part in preventing the cancer in developing countries?
A. The cancer patients. B. The health experts.
C. Community health workers. D. Young women.
5.Which of the following is TRUE according to the passage?
A. The number of cancer cases is decreasing.
B. HIV/AIDS is not being taken seriously in Africa.
C. Over 7.5 million people die of cancer every year.
D. It is very expensive to treat cancer.
