Pilates,yoga and the running machine get all the attention when it comes to popular ways to stay healthy.There is,however,a more humble exercise that might not be so attractive,but has all the benefits-walking.
  Certified fitness professional Jolynn Jaekel explains,"What I love about walking is that anyone can do it at any age and any fitness level.Plus,it is good for your heart,your head and your wallet."
  A recent report details the health benefits of walking.The report found that walking regularly to fulfill the 150 minutes of moderate physical exercise every week,recommended by the UK's chief medical officer,could save 37，000 lives each year.Scientists at the Lawrence Berkeley National Laboratory in California found that quick walking reduces the risk of heart disease more effectively than running.They observed participants aged between 18 and 80 over a six-year period and found that walking reduced the risk of heart disease by 9.3%，while running reduced it by 4.5%.And there is even more good news：30 minutes of quick walking over five days could help you sleep easily,according to research by Oregon State University.The study by the university showed that walking helped participants sleep better and feel more alert during the day.The sooner you get started,the sooner you'll notice the differences in your mind and body.So,go out for your 30-minute walk in a nearby park or green space.

Many people believe eating healthily is expensive-and more costly than buying junk foods.But our new research, published in the BMC Public Health, shows this isn't the truth.
   Most of the Australian family food budget（预算） is being spent on junk foods and drinks that are high in fat, sugar and salt.
  Less than 7% of Australians eat healthily.The Australian adults get at least 35% of their energy from junk foods and drinks.As a result, two-thirds of adults（63%） and one quarter of children are overweight.
  We used the Australian Health Survey 2011-2013 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 socio-economic（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 spends 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 socioe-conomic area, a family of two adults and two children spends ﹩640.20 every two weeks on their present diets, but could buy a healthy diet for ﹩560.93 every two weeks.In the high socio-economic area, these numbers are ﹩661.92 and ﹩580.01.
  Supermarket food prices were about 3% higher in the high socioeconomic location.Takeaway foods were also relatively more expensive, but sugary drinks were priced similarly in both areas.
  Present diets cost more than healthy diets, so causes other than price must be helping to drive preferences for unhealthy choices.



What did the researchers find？ ______

A. Australians have a preference for sweet foods.
B. Most Australian kids have fat problems.
C. Half Australians live on junk foods.
D. Most Australians eat unhealthily.

How did the researchers get the result？ ______

A. By making a comparison.
B. By doing the study online.
C. By carrying out interviews.
D. By asking personal questions.

What can we learn from Paragraph 5？ ______

A. Australian foods are healthier.
B. A healthy diet is actually cheaper.
C. Health foods are becoming more expensive.
D. People choose junk foods for their low prices.

  The Internet brings us many advantages.
  With the Internet,people can send and receive emails.On the Internet,people can skim over news.Using the Telnet,the user anywhere on the Internet can log（登录）into any other machine on which he has an account.It is possible to use the FTP（File Transfer Protocol）program to copy files from one machine on the Internet to another.
  But the Internet also brings us troubles.
  Internet use seems to cause a fall in psychological（心理的）health,according to researches at Carnegie Mellon University.Even people who spent just a few hours a week on the Internet experienced more depression and loneliness than those who logged on less often,the two-year study showed.And it wasn't that people who were already feeling bad spent more time on the Internet,but that using the Net actually seemed to cause the bad feelings.
  Researchers are puzzled over the results,which were completely opposite to what they had expected.They expected that the Net would prove socially healthier than television,since the Net allows users to choose their information and to communicate with others.
  The fact that Internet use reduces time used for family and friends may be the reason for the drop in health,researchers said.Faceless,bodiless "virtual（虚拟的）" communication may be less psychologically satisfying than actual conversations,and the relationships formed through it may not be so deep.Another possibility is that exposure to the wider world through the Net makes users less satisfied with their lives.
  " But it's important to remember this is not about the technology；it's about how it is used，" said one of the researchers."It really points to the need for considering social factors when you design new inventions."



The writer mainly wants to tell us that ______ ．

A. the Internet can bring people many advantages
B. the Internet use may cause psychological problems
C. the Internet users are not satisfied with their lives
D. we shouldn't use the Internet

Why are the researchers puzzling over the results？ ______

A. Because the results were completely different from what they had thought.
B. Because the Net proved socially healthier than television.
C. Because the Internet users were all healthier.
D. Because the Internet users experienced less depression and loneliness.

What may be the reasons why the Internet use causes a fall in psychological health？ ______

A. Internet use reduces time used for family and friends.
B. Virtual communication is less psychologically satisfying than actual conversations.
C. Exposure to the wider world through the Net makes users less satisfied with their lives.
D. All the above.

What does the underlined part in the last paragraph mean？ ______

A. What matters is not the technology but how it is used.
B. This passage is not about the technology but about how it is used.
C. We should remember to learn about the technology.
D. We should remember to learn how to use computers.

Recently,few samples of mice with diabetes（糖尿病）in an experiment showed signs of recovery. Then there arose much discussion regarding the morality of such animal-testing procedures,especially since many unfortunate samples lost lives.  Is it moral and necessary to make sacrifices to benefit the majority？Or are these procedures merely an immoral and unnecessary waste of lives.
  Some people assume that it is acceptable to make sacrifices for the greater benefits because it can provide a more accurate insight to promote the progress of science. Through the test,we are able to obtain more accurate and reliable results that can lead to beneficial scientific progress to help the majority.  Scientists believe that sacrificing real animal samples can give more accurate insights compared to abstract computer modeling. For example,researchers who have conducted experiments on mice for Parkinson's disease have found more promising results which could reverse the symptoms of this previously incurable disease. Therefore,the long-term benefits are more important than the short-term sacrifices.
  However,others have argued that these acts are morally inappropriate especially since we have advanced to the point where there are more moral alternatives at present.  They believe that everything has an alternative as long as effort and money are placed. With the presence of better and more moral alternatives,there is no reason and moral room to sacrifice,even if it is for the larger benefits.
  In all,the samples' sacrifice is unavoidable due to their potential to attain great scientific progress. Research has shown that the cases having better and more moral alternatives are in rare exception,and most alternatives actually end up compromising other moral boundaries instead. However,if there exist such alternatives to some of the scientific procedures,we should try.

Utah Lake is,in a word,disgusting. The State of Utah has worked with many partners and spent millions of dollars in an attempt to restore Utah Lake. It has indeed produced some active effects.  However,due to the waste water getting into it,this body of water is rich in  nutrient and home to water bloom.  Over fishing and the introduction of invasive species have only made the problem worse. In the summer of 2016，500 people in Utah complained about their headaches, skin rashes and discomfort after swimming in the lake.
  The Utah Lake Restoration Project is headed by Parker. He imagines a beautiful lake dotted with man-made islands where a community could be built. Parker frequently goes to Capitol Hill to push for the proposal of the comprehensive lake restoration. Parker follows his rules "big ideas are worth approaching"，as the project calls for lake digging,the creation of islands,the removal of invasive species to restore the habitats of native plants,fish and so on.
  Speaking of the Utah Lake Restoration Project,Ben Holcomb said,"It is not quite in line with reality." He added,"Despite impressive computer models and the current project report,the Utah Lake Restoration Project lacks the actual field research to show that this project will have a positive effect on the lake's ecosystem."
  When asked how the public would help beautify Utah Lake,the lake's official workers suggested picking up garbage. However,it has a greatly limited effect on the overall health of the lake. Parker's plan may seem like the state's best chance to restore Utah Lake,but in reality the Utah Lake Restoration Project lacks the facts necessary for this sort of proposal. The State of Utah should propose some suggestions for the revision of the plan and offer the Utah Lake Restoration Project the access necessary to conduct research which could be compared with their theoretical findings. Only then can the State of Utah make an educated decision on behalf of people and resources.



What can we learn from paragraph l？ ______

A. The State of Utah has tried to restore Utah Lake.
B. It is not difficult to save Utah Lake for the State.
C. People living around Utah Lake are healthy and happy.
D. People don't swim in Utah Lake because of its pollution.

What's the purpose of the Utah Lake Restoration Project？ ______

A. To build a community near Utah Lake.
B. To make the water of Utah Lake rich in nutrient.
C. To make Utah Lake popular with foreign tourists.
D. To build a safe home for native creatures in Utah Lake.

What's Ben Holcomb's attitude towards the Utah Lake Restoration Project？ ______

A. Doubtful.
B. Optimistic.
C. Unconcerned.
D. Approving.

What does the author intend to tell us in the last paragraph？ ______

A. Picking up garbage is the key to saving the whole lake.
B. There's no proper way to save the health of Utah Lake.
C. Parker's plan needs some field research and adjustment.
D. Local people should take responsibility for saving Utah Lake.

During the two and a half years since I settled down in Germany,I've caught a cold several times and gotten to experience how different German cold remedies（疗法）are from the Chinese ones.
  Back in Taiwan, whenever I had a streaming nose and a dry throat, I'd rush to the hospital to get prescribed medicine. For a fever,I would receive a red pill,which I now know is a type of antibiotic（抗生素）.
  Another thing I know now is that the criminal behind my cold is a virus. The drugs I used only relieved the symptoms. When I went to a German hospital intending to get some medicine to treat my cold,I got nothing more than a pat on my shoulder and words from the doctor, saying that I should get some really good rest. The first time this happened,I was shocked. I wondered how I could put up with my sickness without the help of medicine. But the longer I stayed in Germany,the better I knew how to self-medicate as other Germans do.
  I learned to take vitamin C to build up my resistance. But what I like the most is drinking "Erkaltungstee". For German people, Krkaltungstee is what their grandmother gives them when they catch a cold. It's a tea bag mainly made of lime flower and orange rind. Another popular cold remedy in Germany is chicken soup. During my first winter in Germany,I got a really bad cold. My neighbor brought me a bowl of chicken soup to make me feel better. It contained a lot of ginger,onion,garlic,carrots and celery. Germans believe these ingredients are perfect for helping your body recovers.



How did the author feel after seeing the German doctor？ ______

A. Relieved.
B. Surprised.
C. Satisfied.
D. Stressed.

According to the author, what effect do antibiotics have on his cold？ ______

A. They cure his cold.
B. They prevent the disease.
C. They kill the virus in him.
D. They make him feel better.

What do Germans think of "Erkaltungstee"？ ______

A. It can replace any cold remedy.
B. It can build up one's resistance.
C. It's a good way to self-medicate.
D. It's better than chicken soup.

What can we infer from the text？ ______

A. Germans tend not to use antibiotics to treat cold.
B. The author often catches a cold in Taiwan.
C. The author seldom drinks chicken soup.
D. German doctors are cold to patients.
