New research has found that even if you give up smoking, the damage it has done to your genes (基因) will stay there for a much longer time.

In the research, a team of US scientists studied the blood of 16, 000 people. Among them, some were smokers, some used to smoke, and the rest were non­smokers. Scientists compared their genes and found that more than 7, 000 genes of smokers had changed—a number that is one­third of known human genes.

According to NBC News, both heart disease and cancer are caused by genetic changes. Some people may have had the changes when they were born, but most people get them in their day­to­day lives while doing things like smoking.

When you stop smoking, a lot of these genes will return to normal within five years. This means your body is trying to heal (治愈) itself of the harmful effects of smoking. But the changes in some of the genes stay for longer. They can stay for as long as 30 years. It’s almost like leaving a footprint on wet cement (水泥) — it will always be there, even when you’ve walked away and when the cement becomes dry.

Although the study results may make people unhappy, there is a bright side:the findings could help scientists invent medicine to treat genetic damage caused by smoking or find ways to tell which people have heart disease or cancer risks.

Can storms in Africa cause asthma(哮喘) in the Caribbean(加勒比)? Islanders point to the desert insects that land on beaches after a 5,000-kilometer flight across the Atlantic. If they can use winds to get from one continent to another, so can clouds of dust that carry disease.

Scientists think that as Africa becomes drier, dust from expanding deserts is being blown away into Caribbean islands. A study in Barbados shows that asthma has increased 17 times since Africa’s drought(干旱) began in 1973.

Other forms of life are suffering, too. Among them are the Caribbean’s famous coral reefs( 珊瑚礁), which began dying in large numbers in the 1900s. Eugene Shinn of the U.S. Geiological Sudrvey(USGS) in Florida went to the virgin Islands to study the reefs. The tests he and his colleagues carried out showed that the coral was dying of disease caused by Africa microbes(微生物) from across the ocean.

William Sprigg of the University of Arizona is studying the problem as part of a major UN project. He says that dust is causing problems in the U.S., too.

“We are just beginning to collect the evidence of airborne(空气传播的) dust influences on human health,” he told The Washington Post.

1.Which of the following can be the best title for this passage?

2. Where does the dust talked about in this passage come from?

3. The increase of asthma in the Caribean is probably related to _____ according to scientists.

4.Which of the following is NOT true about the Caribbean coral reefs?

5. Which of the following is TRUE about William Sprigg?

However, as for the more severe cases, people have gone on to develop viral（病毒性的） pneumonia, and all the deaths have been among those people.

Who does this virus attack?

As we can see, older people are ending up in hospital with the virus. Most of the affected people are usually over 40 years old. 3.. Basically their immune(免疫) systems are not very strong, and they’re going to find it very hard to fight off a virus.

There are a lot of people who are overweight all over the world. What causes obesity? If you get the gene(基因), well, probably you are going to be a few more pounds heavier compared to the rest of your classmates or friends. 1. Obesity can not only make a person look heavy, and not in the usual sense of being handsome, but can also lead to serious health conditions and life-threatening diseases.

2. Indeed, junk food has been blamed for the prevalence(流行）of obesity. It is called junk food, because hamburger, pizza and the like contain high calories. If you eat a Big Mac (a super hamburger), an order of large fries, and a large Coke, you will need to walk non-stop for six hours to burn off the calories you have gained. And don’t be fooled by soft drinks, which are high in sugar and are a major cause of obesity.

3. Popular sugary drinks, of course, include Coca Cola, Pepsi(百事) Cola, and many new brands that appear on the market every couple of days.

4. Just one 20-ounce (about 567g) bottle of soda can have 250 calories, which are equal to more than 16 teaspoons of added sugars. Even a lemon-flavored iced tea can have 210 calories.

5. Next time, when you are ready to eat that huge Mac and to drink that two-liter bottle of Pepsi, probably it’s a good idea to give it a second thought.

A. Obesity is more common in women than men.

B. Most people don’t realize how easy it is to gain weight from drink sugar-sweetened beverages(饮料)

C. When we talk about obesity, the first thought that comes to mind is: junk food.

D. The unburnt calories will put weight on you.

E. Keeping healthy is our own responsibility.

F. Because of their high content of sugar, soft drinks are also called sugary drinks.

G. However, the most common cause of obesity is eating too much, especially too much junk food.
