Many people believe eating healthily is expensive and more costly than buying junk foods. But our new research, published in the BMC Pubic Health ,shows this isn’t the truth.

Less than 7% of Australians eat healthily. Most of the Australian family food budget is being spent on junk foods and drinks that are high in fat, sugar and salt. As a result, two-thirds of adults （63%）and one-quarter of children are overweight.

We used the Australian Health Survey 2016-2017 and the suggestions of the Australian Dietary Guidelines to model healthy diets for a family of two adults and two children every two weeks. We collected food prices in supermarkets and stores in high and low-socioeconomic（社会经济地位低的）areas in Brisbane, and compared the diet prices with family incomes.

In both areas, a family of two adults and two children spend about 18% more on present diets than would be required to buy healthy diets. About 58% of the food budget for present diets is spent on junk foods, including takeaway foods（14%）, and sugary drinks（4%）. In the low-socioeconomic area, a family of two adults and two children spend $640.20 every two weeks on their present diets, but could buy a healthy diet for $5560.93 every two weeks. In the high socioeconomic area, these numbers are S661.92 and $580.01.

Present diets cost more than healthy diets, so it is surely not the price that helps to drive preferences for unhealthy choices.

1.What did the researchers find?

A.Most Australians eat unhealthily.

B.Half Australians live on junk foods.

C.Most Australian kids have fat problems.

D.Australians have a preference for sweet foods.

2.How did the researchers get the result?

A.By doing the study online. B.By making a comparison.

C.By carrying out interviews. D.By asking personal questions.

3.What can we learn from Paragraph 4?

A.A healthy diet is actually cheaper.

B.Australian foods are becoming healthier.

C.People choose junk foods for their low prices.

D.Healthy foods are becoming more expensive.

4.What might the following paragraph be about?

A.The harm of junk foods. B.How we can eat healthily.

C.Why people choose junk foods. D.The advantages of a healthy diet.

When it comes to medical care, many patients and doctors believe "more is better." But what they do not realize is that overtreatment-too many scans, too many blood tests, too many procedures-may bring harm. Sometimes a test leads you down a path to more and more testing, some of which may be attacking, or to treatment for things that should be left out.

Terrence Power, for example, complained that after his wife learned she had Wegener's disease, an uncommon disorder of the immune system(免疫系统), they found it difficult to refuse testing recommended by her doctor. The doctor insisted on office visits every three weeks, even when she was feeling well. He frequently ordered blood tests and X-rays, and repeatedly referred her to experts for even minor complaints. Even when tests came back negative, more were ordered, and she was hospitalized as prevention when she caught a cold. She had as many as 25 doctor visits during one six-month period. The couple was spending about $30,000 a year for her care.

After several years of physical suffering and near financial ruin from the medical costs, the couple began questioning the treatment after discussing with other patients in online support groups. "It's a really hard thing to determine when doctors have crossed the line," Mr. Power said. "You think she's getting the best care in the world, but after a while you start to wonder: What is the purpose?" Mr. Power then spoke with his own primary care doctor, who advised him to find a new expert to oversee Mrs. Power's care. Under the new doctor's care, the regular testing stopped and Mrs. Power's condition was stable. Now she sees the doctor only four or five times a year.

1.Which of the following was a problem for Mrs. Power during her medical treatment?

A.She had to be hospitalized for three weeks whenever she had a cold.

B.Her doctor asked her to consult other experts for her complaints.

C.When test results showed she was fine, her doctor still ordered more tests.

D.She did not have any insurance, so she became penniless.

2.When did the Powers start to doubt the treatment of Mrs. Power?

A.After they knew about the treatment of other patients.

B.After they analyzed the results of her blood tests

C.After Mrs power was cured of her illness.

D.After the new expert tested her.

3.Which of the following can replace the underlined word "stable" in the last paragraph?

A.not getting worse B.improper

C.unchangeable D.uncertain

4.What is the main idea of this passage?

A.Treatments do not always cause harmful side effects.

B.Patients tend to believe more testing is better treatment.

C.Doctors generally recommend office visits that are necessary.

D.Too much medical care may not be beneficial to patients.

The world is becoming more and more connected, but many people feel lonely in the midst of it. You might not feel lonely right now, but there might be times when you do. Here are some tips on dealing with loneliness:

Be positive about yourself. 1. If you constantly think of yourself as ugly, mean, or unattractive, then it will be difficult for you to connect with others. You must accept yourself before you can accept others. It’s common that you might have some negative qualities. So does everyone else. So in order to get rid of loneliness, you should focus on your positive side and think of yourself in a positive way.

Have an attitude of gratitude (感恩).2. It’s easy to focus on the negatives in life, but don’t forget that there are also many positives. Remember them and be thankful. What does this have to do with loneliness? Well, if you are grateful, then you will become cheerful.3. See the positive side of others. Just as you should see the positive side of yourself, you should also see the positive side of others. Everyone has shortcomings, but everyone also has a positive side.4. That will make you like them and make it easier for you to connect with them.

5. The more you think about yourself, the more likely it is for you to have a pity party and feel lonely. For example, you might think that nobody likes you or cares about you. So it’s important that you shift your attention away from yourself. It can be as simple as smiling at your neighbors or holding a door for a stranger.

A. Join a community group.

B. Do something for others.

C. Negative thoughts can kill you.

D. Instead, try to make more friends.

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

Many people spend more than four hours per day on We Chat, and it is redefining the word “friend.” Does friending someone on social media make him or her your friend in real life?

Robin Dunbar, a professor at Oxford University, found that only 15, of the 150 Facebook friends the average user has, could be counted as actual friends and only five as close friends. We Chat may show a similar pattern.

Those with whom you attended a course together, applied for the same part-time job, went to a party and intended to cooperate but failed take up most of your WeChat friends. In chat records, the only message may be a system notice, “You have accepted somebody’s friend request”. Sometimes when seeing some photos shared on “Moments”, you even need several minutes to think about when you became friends. Also, you may be disturbed by mass messages (群发信息) sent from your unfamiliar “friends”, including requests for voting for their children or friends, links from Pinduoduo.com (a Chinese e-commerce platform that allows users to buy items at lower prices if they purchase in groups) and cookie-cutter (千篇一律的) blessings in holidays.

You would have thought about deleting this type of “friends” and sort out your connections. But actually you did not do that as you were taught that social networking is valuable to one’s success. Besides, it would be really awkward if they found that you have unfriended them already. Then, you keep increasing your “friends” in social media and click “like” on some pictures that you are not really interested. But the fact is that deep emotional connections do not come with the increasing number of your friends in social media.

If the number of your friends reaches 150, maintaining these relationships can be tough to you, and sometimes even will make you anxious. According to Robin Dunbar, 150 is the limit of the number of people with whom one can maintain stable social relationships.

1.What can we learn from Robin Dunbar's finding in Paragraph 2?

A. A Facebook user has 250 friends on average.

B. Most of the social media friends can be actual friends.

C. Among our social media friends, only a few people matter.

D. Only 15 people of a person’s Facebook friends can be close friends.

2.What does the third paragraph tell us about most of your WeChat friends?

A. You have deep communication with them.

B. You benefit a lot from their mass messages.

C. You just have a nodding acquaintance with them.

D. You become friends with them in important occasions.

3.What does the underlined word “that” in Paragraph 4 refer to?

A. Removing unfamiliar friends in WeChat.

B. Strengthening ties with your We Chat friends.

C. Keeping increasing your friends in social media.

D. Clicking “like” on pictures posted by your friends.

4.What can we infer from the last paragraph?

A. We will be anxious if we make friends online.

B. We should avoid making any friends in social media.

C. We should make as many friends as possible in social media.

D. We have difficulty managing relationships with over 150 people.

Many people believe that classical music has nothing to do with young people today. However, this issue(问题) frequently causes heated debate.

Some people say that classical music is associated only with old people. For example, if you look at the audience at a classical concert, the majority is over the age of fifty.

Others say it is more popular than we first imagine. Many young people listen to classical music without realizing it. It is often used in films and advertisements. For example, a famous piece of classical music was used as the theme music for the 1990 World Cup. Not many people could have given its name, but millions enjoyed it.

Also, some people point out that young people produce new music based on classical ideas: for example, it is said that rap(说唱) music was invented by a classical musician in 1912, but it is now used by young people in pop music.

However, young people point to the fact that classical music has been outstripped(超越) by technology. To play a classical instrument, such as a violin, you need to study hard and practice for hours. Nowadays, you don’t need to get aching arms from practicing. A teenager can write and make music using a computer program in the comfort of their own bedroom.

A final point to bear in mind is that the term "classical music" is used to refer to a great variety of music, from jazz to pieces for large orchestras. This makes it even more difficult to say whether classical music is relevant（与…相关） to young people.

So, it may be only a minority of young people who play classical instruments, but when it comes to enjoying classical music, it depends on the piece of music. It may be more relevant to young people in the modern world than they realize!
