Many people believe that heart disease only affects older men.1..The reality is that people of all ages die of heart attacks each year. And while death rates have declined in the U.S. and many western European countries, they are on the rise in the developing world. Yet most heart disease is preventable.

The challenge of heart disease is that it may be silent for years before causing any noticeable problems. No one would have guessed that Barbara Teng would have a heart attack. She was not overweight. “In 2014, the week after I turned 49 when I was on a business trip in Chicago I had a major heart attack," she said. 2. . She now exercises daily and monitors her heart health.

Dr. Patrice Nickens who is with the National Heart Lung and Blood Institute thinks that heart disease is 82 percent preventable. “3. ,” she said .“Men are also facing the same problem and the key to staying healthy is knowing your numbers”. “Your weight ,your blood cholesterol blood sugar and your blood pressure are important numbers that can help you take action and reduce your risk ,” she said.4..“And the steps to take are simple: don’t smoke, maintain a healthy weight, exercise, know your numbers and talk to your physician and control these risks,” she said.

African-Americans are at higher-than-average risk for heart disease and stroke; people don't even know they have it, which increases the risk. Medstar Washington Hospital Center is trying to reach this population.5. .For example, they help the people monitor their blood pressure. If people realize they are at risk for heart disease ,they'll make lifestyle changes: lose weight ,exercise, eat the right foods and keep in touch with a doctor.

A. With the right training, they can play an important role in community health

B. A healthy lifestyle can prevent heart disease

C. Lack of exercise causes heart attacks

D. It is the leading cause of death for women

E. This is a set idea that is not true

F. And that changed her life

G. So we must cure heat disease

Many people believe that you lose the ability to learn new languages as you get older. Language experts, however, will tell you that you’re never too old to learn a new language. As you get older, it can be more difficult to learn a new language, though.

Children and adults learn new languages in different ways. For children, language is their life. They study for thousands of hours every year, because they need to learn languages to become part of their communities. Adults, on the other hand, are already part of a language community. Learning a new language means becoming part of another language community, and adults rarely get the chance to practice as much as young children do.

Moreover, children learning a new language are expected to make mistakes. This gives them freedom when learning to be daring and confident. Adults, however, often feel pressured to be perfect when learning a new language. This can discourage many people and make it even harder to learn a new language.

When young children learn a new language, they come to see various languages as a “normal” part of society. This mindset （思维模式） helps them embrace learning a new language without feeling like they’re doing something unusual or “too hard”.

So if you want to learn a new language, go for it! It’s never too late to learn a new language. If you’re older, it may take more work, but it can be done. If you’re a young child, though, now is the time to step out and learn a new language!

1.By “Language is their life”, the author means that children ________.

A. can’t live without language

B. lead a happy life every day

C. practice a new language a lot

D. are taken good care of adults

2.What may make it hard for the old people to learn to a new language?

A. They are afraid of being laughed at.

B. They usually have too many interests.

C. They think making mistakes is natural.

D. They always make all kinds of mistakes.

3.Which of the following shows the difference between children and adults in learning a new language?

A. The behaviors they have.

B. The learning attitudes.

C. The future plans they have made.

D. The materials they are using.

4.According to the author, a new language ________.

A. can never be learned by the old people

B. can be grasped by the old people easily

C. can be understood only by the old people

D. can be learned by both the old and the young

A super drug that could remove Alzheimer’s (老年痴呆症)，heart disease and diabetes (糖尿病) and help people live to 100 is being developed by scientists. Their research is based on the identification of three genes that help prolong lives and prevent diseases which occur in old age. Medically controlling the proteins made by the “ longevity genes” will allow millions to live longer, predicts Dr Nir Barzilai.

Those whose DNA strongly features the three genes are 80 percent less likely to develop Alzheimer’s. The genes also fight against the deadly impact of smoking, poor diet, obesity and lack of exercise.

Already, several laboratories are working on a pill to imitate the benefits of the genes and Dr Barzilai thinks it could be tested within three years. The pill could remove some diseases that damage old age. “ The advantage of finding a gene that involves longevity is that we can develop a drug that will imitate exactly what this gene is doing,” he said.

Of the three longevity genes, two genes increase the production of so-called good cholesterol(胆固醇), which reduces the risk of heart disease. The third prevents diabetes. They were discovered by Dr Barzilai’s team while studying the DNA of 500 Ashkenazi Jews with an average age of 100. The chances of living that long are one in 10,000 but the group, which shared relatively few common ancestors, was 20 times more likely to hit the entury. Dr Barzilai said: “ 30 percent of them were obese or overweight and 30 percent smoked two acks of cigarettes a day for more than 40 years, however they can live to 100.”

But Andrew Ketteringham of the Alzheimer’s Society said: “Alzheimer’s disease, a most common disease, is likely to be caused by a combination of genetic disosition(遗传倾向), lifestyles and life events. Many genes are probably involved.

1.Some people are able to live to 100 years because of ______.

A. a magical medicine  B. three special genes    C. good living habits     D. longevity proteins

2.Why does the discovery of the longevity genes mean a lot?

A. Because it can bring great benefits to scientific labs.

B. Because it can help people change their unhealthy genes

C. Because it helps produce a drug that can make people live longer.

D. Because it will help scientists build up a new branch of biology.

3. From Paragraph 4 we can infer that ________.

A. longevity genes can create good cholesterol.

B. the volunteers share some common ancestors

C. bad habits are likely to have no effect on the volunteers

D. longevity genes protect the volunteers against bad habits

4.What is Andrew Ketteringham’s attitude toward the study?

A. Positive    B. Negative         C. Critical                 D. Cautious

There are many older people in the world and there will be many more. A little-known fact is that over 60 percent of the older people live in developing countries. According to the World Health Organization, by 2020 there will be 1 billion, with over 700 million living in developing countries.

It is a surprising fact that the population aging is particularly rapid in developing countries. For example, it took France 115 years for the rate of older people to double from 7 percent to 14 percent. It is estimated to take China a mere 27 years to achieve this same increase.

What are the implications of these increased numbers of older folk? One of the biggest worries for governments is that the longer people live, the more likelihood there is for diseases and for disability. Attention is being paid to the need to keep people as healthy as possible, including during old age, to lessen the financial burden on the state.

Another significant problem is the need for the younger generations to understand and value the older people in their society. In some African countries, certainly in Asia, older people are respected and regarded as the ones with special knowledge. Yet traditions are fading away daily, which does not make sure the continued high regard of older people. As society changes, attitudes will change.

Much needs to be done to get rid of age discrimination in employment. Life-long learning programs need to be provided to enable older people to be active members in a country's development.

Social security policies need to be established to provide adequate income protection for older people. Both public and private schemes are vital in order to build a suitable safety net.

1.The rate of older people________.

A. is bigger in developed countries than in developing countries

B. is one-seventh of the population in developing countries

C. will increase much faster in China than in France

D. will be sixty percent in developing countries by 2020

2.According to passage, which of the following are governments most worried about?

A. The diseases and disability of older people

B. The longer life and good health of people.

C. The loss of taxes on older people.

D. The increasing respect for older people.

3.Which of the following measure is NOT mentioned to solve the population ageing problem?

A. Getting rid of age discrimination in employment.

B. Supplying life-long learning programs to older people.

C. Making sure adequate income protection for older people.

D. Providing free health care for sick older people.

4.The author concludes in the last paragraph that ________.

A. governments have spent lots of time in solving the aging problem

B. population aging is a hard problem, but it needs to be solved urgently

C. people are too busy to solve the population aging problem

D. much time and effort will be lost in solving the aging problem

A while ago, people used to believe that only humans can use tools — but Jane Goodall showed that humans aren’t the only ones to do so. We’ve since found several species that build and use their own tools. Then, many thought that it’s our cultural and family ties that separate us from the animals. Actually, that’s not true either. Several other species, including whales, have shown important cultural behaviors.

Researchers have found that related whales returned to the same locations year after year, and decade after decade, passing the information from one generation to the next. Researchers analyzed the structure of the beluga whale society, finding that migratory culture is inherited（继承）. Furthermore, this cultural inheritance maintains the family ties of beluga whales. This cultural legacy（遗传）is so powerful that some travel as far as 6,000 kilometers each year.

“What interested us most was whether particular whales returned to where they were born or grew up and if this was an inherited behavior,” said Greg O’ Corry-Crowe, Ph.D., lead author and a research professor at FAU’s Harbor Branch. “The only way that we could definitively answer these questions was to find and track close relatives from one year to the next and one decade to the next.”

Researchers also found that beluga whales exhibit an impressively broad range of vocal repertoires and acoustic systems（复杂的声音体系）which suggests that they form complex interpersonal relationships. They like to hang out in the thousands near shore during the summer when the ice melts. Eventually, researchers hope that this will not only enable us to better understand these surprisingly complex species but also develop better ways to protect them in the face of a changing environment — the polar regions, where the beluga whales live, are extremely exposed to climate change.

“Findings from our study are expanding our understanding of how complicated non- primate（非灵长类）societies can be and how important culture is for the survival of these species,” said O’ Corry-Crowe. “Our findings also will influence our thinking in terms of how populations and species are going to adapt to dramatic environmental changes. There are few places where this is more urgent than in the rapidly changing polar regions.”

1.According to the passage, whales usually 　　　　　 .

A. produce their tools　　 B. use their own tools

C. live near the coast　　 D. have their cultural ties

2.It can be inferred that migratory culture has 　　　　　 .

A. a short and insignificant effect on beluga whales

B. inherited from the structure of beluga whale society

C. a long and far-reaching effect on beluga whales

D. attracted beluga whales to several fixed locations

3.What’s the purpose of the research?

A. To find beluga whales’ behaviors.

B. To find beluga whales’ acoustic systems.

C. To find beluga whales’ interpersonal relationships.

D. To better understand and protect beluga whales.

4.Why does O’ Corry-Crowe consider it urgent to understand beluga whales’ adaption to their surroundings?

A. Because of the very sophisticated non-primate societies.

B. Because of the rapid environmental changes in polar regions.

C. Because of the misunderstanding of beluga whales’ migrations.

D. Because of the too far distance for beluga whales to migrate.

Alzheimer's disease（老年痴呆症）affects millions of people around the world. American researchers say the disease will affect more than one hundred million people worldwide by the year twenty fifty. That would be four times the current number. Researchers and doctors have been studying Alzheimer's patients for a century. Yet the cause and the cure for the mental sickness are still unknown. However, some researchers have made important steps towards understanding it.

Several early signs of the disease involve memory and thought processes. At first, patients have trouble remembering little things. Later, they have trouble remembering more important things, such as the names of their children.

There are also some physical tests that might show who is at risk of developing Alzheimer's disease. The tests look for proteins in brain and spinal cord(脊髓) fluid. The proteins appear to be found only in people with the disease. The protein tests correctly identify the presence of the disease in about ninety percent of patients.

Now, a much simpler physical test to predict Alzheimer's risk has been developed. Researchers found that trouble with the sense of smell can be one of the first signs of Alzheimer's. Using this information, they developed a test in which people were asked to identify twelve familiar smells. These smells included cinnamon, black pepper, chocolate, paint thinner, and smoke.

The study continued for five years. During this period, the same people were asked to take several tests measuring their memory and thought abilities. Fifty percent of those who could not identify at least four of the smells in the first test had trouble with their memory and thinking in the next five years.

Another study has shown a possible way to reduce a person's chances of developing Alzheimer's disease in old age. Researchers in Chicago found that people who use their brains more often are less likely to develop Alzheimer's disease. Those who read a newspaper, or play chess or word games are about three times less likely to develop the condition.

Researchers say they still do not know what causes Alzheimer's disease. But they say these findings might help prevent the disease in the future.
