About a third of all common cancers in the United States, China and Britain could be prevented each year if people ate healthier food, drank less alcohol and exercised more, health experts said on Friday.
Reports from the World Cancer Research Fund (WCRF) suggest that making simple lifestyle changes could prevent some 40 percent of breast cancers alone in Britain and the United States, as well as tens of thousands of stomach cancers.
“Even in 2011, people are dying unnecessarily from cancers that could be prevented through keeping a healthy weight, diet, physical activity and other lifestyle factors,” said a WCRF medical and scientific adviser.
WCRF findings are supported by World Health Organization (WHO) reports, which say regular exercise can prevent many diseases such as cancers and heart diseases.
Cancer is a leading cause of death around the world and its incidence(发病率) is rising. Each year around 12.7 million people discover they have cancer and 7.6 million people die from some form of the disease. There are about 200 known types of cancer.
Rachel Thompson, the WCRF’s head of science, said that while the message was simple — that not smoking, eating good food and being a healthy weight can help ward off many cancers — it was still a difficult one to get across.
The WHO says adults should do at least 150 minutes of exercise a week. This could be done by walking for 30 minutes five times per week or by cycling to work every day.
Peter Baldini, head of the World Lung Foundation, also called on all governments to introduce smoke-free laws and raise the price of cigarettes. Tobacco kills millions of smokers every year, and tobacco-related lung cancers also kill hundreds of thousands of people who don’t smoke but have been exposed to it second-hand.
“There isn’t a magic bullet to cure all forms of cancer, but we have the opportunity and the duty to protect people from developing cancer wherever possible,” Baldini said.
1.Which of the following words can best take the place of the phrase “ward off” in the sixth paragraph?
A. protect B. prevent C. develop D. cure。
2.Which of the following statements is Not true according to the text?
A. Exercising and eating healthily can help to reduce cancer risk.
B. Each year about 12.7 million people are diagnosed with cancer around the world.
C. Every year millions of people die from smoking and lung cancers.
D. Adults should walk for fifty minutes three times per week.
3.Which of the following can be the best title of this text?
A. Simple life changes could stop millions of cancers
B. Cancer is a leading cause of death
C. Our bad lifestyle caused many diseases
D. The incidence of common cancers is rising
4.By writing the passage, the author mainly intends to ____.
A. advise people to develop healthier lifestyle.
B. warn people of the danger of cancers
C. explain why many people die from cancers every year.
D. introduce the ways to protect people from developing cancers
5.We can infer from Peter Baldini’s opinion in the last two paragraphs that ____.
A. all the lung cancers are linked to smoking
B. there is no medicine to cure the cancers but it’s our duty to find one
C. all governments should take measures to control smokers and protect people’s health

More than one-third of adults in the United States are obese(肥胖). In fact, over obesity has reached such proportions that one big-city mayor has gone about banning large-sized, sugary soft drinks and the First Lady has been on a campaign to control the dietary offerings in public schools.
Even many adults who do not fit the clinic definition of obesity are still overweight, and a large percentage are looking for the best ways to lose weight.
Reducing pounds largely comes down to the two-sided factors of diet and exercise. Not carrying out the first one enough, and not getting enough of the second one, ends up giving the individual a recipe for being overweight.
Advising someone to eat less and exercise more might be the easiest advice possible, but it’s also, partially, an oversimplification. Dieting has more to do with the types of food you eat than how much you eat. Reduce the amount of red meat in your diet. If you don’t want to eliminate red meat altogether, choose cuts of meat with less fat content. Limit your intake of salt and starches. If you’ve got to have potato chips alongside your sandwich at lunch, choose the baked potato chips that contain less fat than the deep-fried chips. You might find you’re really not sacrificing that much in terms of taste.
A diet rich in fruits, vegetables, egg whites, fish and nonfat dairy products will certainly aid in the mission of losing weight. Drink more water and less sugary drinks. If you have to have a soda, a diet soda is a better option, but seltzer is an even better choice than that.
It’s important—if not always easy—to make sure you get at least some physical activity each and every day. If your feet won’t allow for a regular jogging regimen, then make sure you take lots of walks. Next time you need to mail a letter, walk to the mailbox instead of driving. Try to work in a daily walk in your neighborhood.
1. You should when you want to lose weight
A. try not to fit the clinic definition of obesity
B. diet as well as exercise enough
C. get little exercise every day
D. focus your attention on diet only
2.The First Lady has started a movement to .
A. raise people’s awareness of healthy diet
B. control the public school dietary supplying
C. ban the sugary soft drinks
D. realise the importance of dieting
3. What can we learn from the fourth paragraph?
A．We must keep far away from fat and ignore our taste.
B．The simplest and best way to lose weight is to eat and exercise more.
C．We should remove the red meat in our diet completely to reduce weight.
D．When it comes to diet, no one needs to starve themselves in order to lose weight.

People elect a mayor (市长) to help run a city in the United States. The mayor must keep track of all city activities. 1. They run the city government with the help from city council (市议会).
Mayors may be “weak” or “strong.” In cities that use a weak-mayor system, the city council has most of the power. Under this system, people elect council members and leaders of some departments, or city offices. 2. A city may have many boards and committees, which are groups that make decisions. Each group manages one city department. Although people elect the mayor, he or she has little power. The weak mayor may suggest leaders for city departments. However, the council must approve these suggestions.
In a strong-mayor system, the elected mayor chooses the leaders of each department. 3. The elected city council doesn’t have the power to approve the leaders that the mayor chooses. Strong mayors check the work of many different city departments. These departments plan the way that the city will grow and develop.
