Smoking is harmful. But as soon as you quit the habit, everything will be OK, right?

Wrong

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 non-smokers. Scientists compared their genes and found that more than 7,000 genes of smokers had changed—a number that is one-third 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 day-to-day 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.

1.The function of Paragraph 1 is to ________.

A. show the main idea of the passage　　 B. give an example

C. make an argument　　 D. introduce the topic of the passage

2.Most genetic changes happen because of ________.

A. people’s condition at birth　　 B. people’s bad living habits

C. environmental pollution　　 D. heart disease and cancer

3.The underlined word “it” in Paragraph 6 refers to ________.

A. the genetic change　　 B. the cement

C. the harmful effect　　 D. the footprint

4.Which of the following statements is true?

A. The findings are the fruit of more than three years’ research.

B. The findings have prevented more people from starting smoking

C. The findings help to find cures for genetic damage caused by smoking.

D. The findings offer evidence that a damaged gene can heal itself.

WASHINGTON — Money can buy happiness, but only if you spend it on someone else, according to researchers.

Spending as little as $5 a day on someone else could significantly boost happiness, the team at the University of British Columbia and Harvard Business School found on Thursday.

Their experiments on more than 630 Americans showed they were measurably happier when they spent money on others --- even if they thought spending the money on themselves would make them happier.

“We wanted to test our theory that how people spend their money is at least as important as how much money they earn,” said Elizabeth Dunn, a psychologist at the University of British Columbia.

They asked their 600 volunteers first to rate their general happiness, report their annual income and detail their monthly spending including bills, gifts for themselves, gifts for others and donations to charity.

“Regardless of how much income each person made, those who spent money on others reported greater happiness, while those who spent more on themselves did not,” Dunn said in a statement.

Dunn’s team also surveyed 16 employees at a company in Boston before and after they received an annual profit-sharing bonus of between $3,000 and $8,000.

“Employees who devoted more of their bonus to pro-social spending experienced greater happiness after receiving the bonus, and the manner in which they spent that bonus was a more important predictor of their happiness than the size of the bonus itself,” they wrote in their report, published in the journal Science.

“Finally, participants who were randomly (随机地) required to spend money on others experienced greater happiness than those required to spend money on themselves,” they said.

They gave their volunteers $5 or $20 and half got clear instructions on how to spend it. Those who spent the money on someone or something else reported feeling happier about it.

“These findings suggest that very minor adjustment in spending allocations (分配) --- as little as $5 --- may be enough to produce real gains in happiness on a given day,” Dunn said.

This could also explain why people are no happier even though US society is richer.

“Indeed, although real incomes have increased dramatically in recent decades, happiness levels have remained largely flat within developed countries across time,” they wrote.

1.

Dune’s experiment on 630 Americans was to ________.

A. help people make careful plans for their money                 B. encourage people to be generous to others

C. see how to spend money is important to happiness               D. test whether $5 is enough to buy happiness

2.

What can we conclude according to the experiment?

A. Happiness largely depends on the size of your bonus money.

B. Happiness, as a matter of fact, has nothing to do with money.

C. The more money you give away, the happier person you will be.

D. Spending money for the good of society will make you happier.

3.

How many different ways are used by the researchers to test their theory?

A. Two.               B. Three.             C. Four.            D. Five.

4.

The last sentence of the passage means _______.

A. happiness does not necessary increase as money grows

B. people in richer countries actually have more problems

C. fast economic growth has a bad effect on people’s life

D. great increase of income contributes to keeping happiness level stable

How can you find out what is going on inside a person’s body without opening the patient s body up? Regular X-rays can show a lot. CAT scans can show even more. They can give a complete view of body organs.

What is a CAT scan? CAT stands for a kind of machine. It is a special X-ray machine that gets a 360-degree picture of a small area of a patient’s body.

Doctors use X-rays to study and determine diseases and injuries within the body. X-rays can find a foreign object inside the body or take pictures of some inside organs to be X-rayed.

A CAT scanner，however，uses a group of X-rays to give a cross-sectional (横截面) view of a specific part of the body. A fine group of X-rays is scanned across the body and around the patient from many different directions. A computer studies the information from each direction and produces a clear cross-sectional picture on a screen. This picture is then photo-graphed for later use. Several cross sections, taken one after another，can give clear “photos” of the entire body or of any body organs. The latest CAT scanners can even give clear pictures of active，moving organs，just as a fast-action camera can “stop the action”，giving clear pictures of what appears unclear to the eye. And because of the 360-degree pictures, CAT scans show clear and complete views of organs in a manner that was once only shown during operation or examination of a dead patient.

Frequent appearance before X-rays can cause skin burns, cancer or other damage to the body. Yet CAT scans actually don’t cause the patient to more radiation than regular X-rays do. CAT scans can also be done without getting something harmful into the patient, so they are less risky than regular X-rays.

CAT scans provide exact, detailed information. They can quickly find such a thing as bleeding inside the brain. They are helping to save lives.

1.The underlined words “a foreign object” in Paragraph 3 most probably refer to　　　　 .

A. a badly injured part inside the body

B. a new thing that is unknown to the doctor

C. a strange cell that has grown in the body

D. a thing that gets inside the body by chance

2.What is the special use of the latest CAT scanners?

A. It can take pictures of inside organs.

B. It provides clear photos of moving organs.

C. It won’t cause serious skin bums, cancer or other damage to the body.

D. It helps to find out illness inside a person’s body without opening it up.

3.What can we infer from this text?

A. Patients in front of CAT may suffer a bit of radiation,

B. Doctors need no opening-up of the body with CAT scanners.

C. CAT scanners are more expensive than regular X-ray machines.

D. CAT scanners can take photos of either the whole body or a part of it.

4.What can be the best title of this text?

A. The newest medical invention

B. A special X-ray machine to save lives

C. How to avoid the damage from X-rays

D. Advantages and disadvantages of CAT scanners
