An estimated 60 percent of cats and 50 percent of dogs in the U. S. are overweight or obese, so chances are that your pet needs to lose weight rather than pack on some pounds. It's not always easy to tell if your pet could afford to lose few, but there are some other signs that can tip you off. One important factor the waist, "Most people don't know what a normal cat should look like," says Romine. "But cats should have waists, too." The vet says you should be able to feel your pet's ribs（肋骨） through its coat, and when you look down at them, they should have an hourglass（沙漏）shape---just like person.

"For some overweight pets, you may want to switch to new food entirely; foods with 'light' or 'healthy weight' labels usually have an increased fiber content to help the dog or cat feel fuller," Romine notes. "Another option is to feed them less of the food they currently cat," Freeman suggests. "Make sure you're reducing table scraps（残羹剩饭）and high-calorie treats like pet biscuits," she says.

It's important to figure out what your pet's ideal weight is as you're helping them to lose. Romine advises working with your vet to get the right number, and if you're following the portion guidelines often printed on food labels, feed them the amount of food associated with the weight you want them to be, rather than the weight they currently are.

Food isn't the only factor that can impact your pet's weight. Romine stresses the importance of exercise in keeping your pet healthy. For cats, just 10 minutes of indoor play each day can make a difference. For dogs, letting them out in the backyard to do their business is not enough. You'll have to exercise with your dog to really get them moving.

Doctors in Britain are warning of an obesity time bomb, when children who are already overweight grow up. So, what should we do? Exercise more? Eat less? Or both? The government feels it has to take responsibility for this expanding problem.

The cheerful Mr. Pickwick, the hero of the novel by Charles Dickens, is seen in illustrations as someone who is plump and happy. In 18th century paintings, beauty is equated （使…等同） with rounded bodies and soft curves. But nowadays being overweight is seen as indicating neither a cheerful character nor beauty but an increased risk of heart disease, stroke and diabetes.

So what do you do? Diet? Not according to England's chief medical officer, Sir Liam Donaldson. He says that physical activity is the key for reducing the risks of obesity, cancer and heart disease. And the Health Secretary John Reid even said that being inactive is as serious a risk factor in heart disease as smoking.

So, having bought some cross trainers, how much exercise should you do? According to Sir Liam Donaldson, at least 30 minutes of moderate activity five days a week. Is going to the gym the answer? Luckily for those who think that running machines are boring, the Health Development Agency believes that physical activity that fits into people's lives may be more effective. They suggest taking the stairs rather than the lift, walking up escalators, playing active games with your children, dancing or gardening. And according to a sports psychologist, Professor Biddle, gyms "are not making the nation fit", and may even cause harm.

There's new scientific evidence that too much exercise may actually be bad for you. Scientists at the University of Ulster have found that unsuitable exercise releases dangerous free radicals that can adversely （oppositely） affect normal function in unfit people. The only people who should push their bodies to that level of exercise on a regular basis are trained athletes.

So, should we forget about gyms and follow some expert's advice to reduce sedentary （久坐不动的） activities and increase exercise in our daily life? After all, getting off the bus a stop early and walking the rest of the way can't do any harm! One final thought. How come past generations lacked gym facilities but were leaner and fitter than people today?

1.Mr.Pickwick and the paintings of the 18m century are used as examples to show that_____.

A. beauty should be overweight

B. a fat man is usually a cheerful character

C. fatness was considered something good at one time

D. fatness leads to an increased risk of disease

2.According to Sir Liam Donaldson, we should_____.

A. go on a diet                  B. do regular physical activity

C. give up smoking                            D. go to the gym

3.The underlined phrase cross trainers probably refers to _____.

A. people who help you do exercise                   B. places where you can do exercise

C. a kind of shoes                               D. a form of vehicles

4.At present being overweight indicates _____.

A. an increased risk of diseases                   B. a happier life

C. a cheerful character                          D. a beauty

5.What is the passage mainly about?

A. how to keep fit and avoid fatness.          B. increased risks for overweight people.

C. the dangers of exercise in the gym.                 D. the benefit of a balanced diet.

People who are slightly overweight or mildly obese(肥胖的) have a lower risk of early death than normal weight individuals(个人;个体), according to a new analysis of nearly 100 international studies.

The studies, most conducted within the past decade, included about three million adults from around the world. The result of these studies by researchers at the National Center for Health Statistics in Maryland, part of the U.S. Centers for Disease Control and Prevention, shows that slightly overweight or obese people were six percent less likely to die from all causes compared to people of normal weight. But the researchers found that seriously obese individuals were still at a 30 percent greater risk of death compared to healthy-weight individuals.

Study lead author Katherine Flegal says she was not surprised that overweight people would not have a higher death risk. “Because we'd actually already read a lot of this literature and realized that death rates for overweight would be at least not higher than normal[weight," she said. “I guess l was a little bit surprised that it was definitely lower. And l was also surprised that the lower rates of obesity didn't seem to differ from normal weight."

But Flegal stresses the difference in death rates appear to be small between normal-weight people and overweight and mildly obese individuals.

The finding by Flegal and colleagues have raised new questions about the reliability(可靠性)of the so-called "body mass index" or BMI, a measurement of body fat as a ratio(比例，比率)of height to weight, that has become popular in recent years among public healthexperts to measure potential health risks.

But Heymsfield warns that individuals should not conclude that it's okay to put on extra kilograms, since being at a healthy weight lowers the risk for heart disease and diabetes.

1.Katherine Flegal feels surprised at the fact that____.

A. obese people have higher death rates

B. slightly obese people have lower death rates

C. obese people tend to die early

D. death rates have nothing to do with body weight

2.What do we learn from the fifth paragraph?

A. BMI may not be so reliable.

B. The study provides further evidence for BMI.

C. BMI tells nothing about potential health risks.

D. BMI has been much questioned recently.

3.What can we conclude from the passage'?

A. It's OK to put on extra weight.

B. It doesn't matter if you are slightly obese.

C. Obese people are much healthier.

D. Body weight has nothing to do with death rates.

4.What topic does the passage mainly deal with?

A. Technology.　　 B. Dieting.　　 C. Health.　　 D. Death.

New research shows that overweight or even mildly obese people have a lower risk of early death than people considered to be normal weight.

Researchers examined the results of 97 studies. Most of the studies were less than 10 years old. They included almost three million adults from around the world, including the United States, Canada, China, Taiwan, Brazil, India and Mexico.

The researchers at the National Center for Health Statistics found that people who are considered overweight or slightly obese were five to six percent less likely to die from all causes than people of normal weight. People with higher obesity ratings, however, had almost a 30 percent greater risk of death compared to normal-weight individuals.

Katherine Flegal was the lead author of the study. She says she was not surprised that overweight people would not have a higher risk of death.

“Because we’d actually already read a lot of this literature and realized it was likely that mortality rates (死亡率) for overweight would be at least not higher than normal weight. I guess I was a little bit surprised that it was definitely lower. And I was also surprised that the lower rates of obesity also didn’t seem to differ from normal weight.”

But she says the difference in death rates appears to be small between normal-weight people and those who are overweight or mildly obese.

The study has raised new questions about “body mass index,”（体重指数） or BMI. This is a measurement of body fat as a ratio（比率） of height to weight. In recent years, many public health experts have promoted body mass index as a way to predict the risk of health problems. Bu t a person's BMI can be misleading in some cases.

Steven Heymsfield ,the executive director of the Pennington Biomedical Research Center, says people can be physically fit and in good health, but might weigh more because they are more muscular.

Still, Dr. Heymsfield says people should not think gaining extra weight is OK just because of the new findings. He says being at a healthy weight lowers the risk for heart disease and diabetes（糖尿病）.

1.According to the new findings, the researchers found that __________ .

A.People with high obesity have a lower risk of early death than people with low obesity

B.People with overweight have a greater risk of early death than people of normal weight.

C.People with mild obesity are less likely to die than people of normal weight.

D.People with obesity live much longer than people of normal weight.

2.What does the underlined word “literature” in paragraph 6 mean ?

A.works like novels and poems

B.books and articles on a particular subject

C.printed material

D.magazines and newspapers

3.Which of the following statements is not true according to the passage?

A. BMI is commonly used to measure body fat as a ratio of height to weight.

B. Not all people with a little higher BMI are fat .

C. Many public health experts encourage more people to use BMI as a way to predict the risk of health problem

D. Because of the ne w findings, people should think about gaining extra weight.

The year 2019 was a year of teen power. Young people spoke up about big problems and adults began to listen. Greta Thunberg, the seventeen-year-old Swedish schoolgirl, was perhaps the most powerful example last year of this teen power. At the U.N. Climate Action Summit in September 2019, she told world leaders, “You are failing us young people” by not taking enough action against climate change. Greta gained worldwide attention for her impassioned (激昂的) speech and was named Time magazine's 2019 Person of the Year.

In the United States, teen groups have formed organizations to pressure politicians into changing gun laws to stop school shootings. “The adults know that we’re cleaning up their mess,” says Cameron Kasky, an 11th-grader who started the NeverAgain movement after surviving the deadliest high school shooting in American history in 2018. “It’s like they’re saying, ‘I’m sorry I made this mess’, while continuing to spill soda on the floor,” adds another survivor Emma González.

These problems are not new and politicians have been dealing with them for years. However, as with the most big problems, there are no easy solutions, and each solution may create more problems. Fighting climate change by reducing fossil fuels (化石燃料)-no more cars, airplanes or big industries-can have a negative effect on people’s lives and even increase poverty. And prisons would fill up quickly if we locked up every person who was considered to be a potential criminal.

Teen power is a good thing. However, it will take more than youthful passion to solve the world’s problems. If you are also ambitious to make the world a better place, it is important that you speak up when necessary. But just as important is the need to grow in our learning-to study and to always remain humble（谦卑的）. Apart from enthusiasm for bringing about change, you still need the maturity, wisdom, knowledge and skills to make good decisions.

1.Why does the author mention Greta Thunberg in paragraph 1?

A.To show the success of teen power.

B.To inform readers of 2019 Person of the Year.

C.To introduce the U. N. Climate Action Summit.

D.To encourage readers to speak up about big problems.

2.What does the underlined phrase in paragraph 2 mean?

A.The adults like soda very much.

B.The adults fail to clean up their mess.

C.The politicians haven't stopped making a mess.

D.The politicians have been working on the shooting.

3.What is the author opinion about reducing fossil fuels?

A.It makes no difference to people's life.

B.It will bring about other new problems.

C.It will make the prisons fill up quickly.

D.It is effective in fighting climate change.

4.What does the author want to stress in paragraph 4?

A.Teen power is a good thing to change the world.

B.Passion is important in solving the world's problems.

C.We should speak up to make the world a better place.

D.We need to study to be mature and wise to decide well.
