Many English learners have difficulty deciding what kind of English accent they want to have. A US accent, perhaps modeled on the way a Hollywood star speaks? Or maybe you want to imitate（模仿） the British accent of a BBC news reader?

Young British people find the US accent attractive while young US people like a British accent. Especially when the person speaking is of the opposite sex! Let’s listen to what they have to say.

Stephen Yang, 17, from London, UK

A US accent is cute, especially when a girl speaks it. Whether it’s Jessia Alba speaking or the girl- next-door, the way US girls speak has a sweet tingle that is really sassy(时髦). A girl from Texas recently moved into our neighborhood. Her Texan twang（鼻音） had all the boys here on their knees within seconds of meeting her.

To me, accents reflect the attitudes, characteristics and lifestyles of the people.

Jennifer Sun, 16, from New Jersey, US

From watching English actors like Daniel Radcliffe, my friends and I have developed a soft spot for British men. Some are attracted to the qualities of English males, while others admire their sense of style.

Everyone, however, agrees that the most appealing aspect of an English man is his accent. For example, many American girls watch Harry Potter movies over and over again just to listen to the actors speak.

The English accent seems almost like art.

Elephants have impressed us for centuries. They are big, clever, and sociable. But what if someone told you that they may also hold the key to fighting cancer (癌症)?

People have been wondering why elephants do not develop cancer, even though they have lifespans (寿命) that are similar to humans, living for around 50 to 70 years.

Now scientists believe they know why. A team at the University of Chicago, US has found that elephants carry a large number of genes that stop tumors (肿瘤) from developing. To be precise, they found 20 copies of an anti­tumor gene called TP53 in elephants. Most other species, including humans, only carry one copy.

According to the research, which was recently published on the online science network BioRxiv, the extra copies of the gene improved the animal's sensitivity to DNA damage. This lets the cells quickly kill themselves when damaged before they can go on to form deadly tumors.

“An increased risk of developing cancer has stood in the way of the evolution of large body sizes in many animals，” study author Dr. Vincent Lynch told The Guardian. If every living cell (细胞) has the same chance of becoming cancerous, large creatures with long lifespans like whales and elephants should have a greater risk of developing cancer than humans and mice do. But across species, the risk of cancer does not show a connection with body mass.

This_phenomenon was found by Oxford University scientist Richard Peto in the 1970s and later named “Peto's paradox”. Evolutionary (进化的) biologists believe it results from larger animals using protection that many smaller animals do not. In the elephant's case, the making of TP53 is nature's way of keeping this species alive.

The study also found that when the same genes were brought to life in mice, they had the same cancer resistance (抵抗) as elephants. This means researchers could use the discovery to develop new treatments that can help stop cancers from spreading or even developing in the first place.

“Nature has already figured out how to prevent cancer, ” said Joshua Schiffman, an oncologist at the School of Medicine, University of Utah, US.

“It's up to us to learn how different animals tackle (处理) the problem so we can use those strategies to prevent cancer in people.”

1.Why are elephants unlikely to develop cancer?

A. They have a large body size.

B. Their genes suffer no DNA damage.

C. Certain genes in their body kill existing tumors.

D. They carry many genes that keep tumors from developing.

2.According to Dr. Vincent Lynch, what has been a risk in the evolution of large animals?

A. A risk of deadly tumors. B. Human behavior.

C. Extreme weather. D. Cells killing themselves.

3.What does the underlined expression “This phenomenon” in the sixth paragraph refer to?

A. Larger animals have protection from TP53.

B. The risk of cancer is not related to body size.

C. The larger animals are, the bigger risk of cancer they have.

D. Larger animals suffer the same risk of cancer as smaller ones do.

4.We can conclude from the last three paragraphs that ________.

A. humans are expected to stop cancer in the near future

B. depending on nature is not enough to fight against cancer

C. this new treatment is more effective than the present ones

D. the TP53 genes have proven useful in stopping cancer in mice

Recently some American scientists have given a useful sincere piece of advice to people in industrialized nations that they would be much healthier if they ate more of the same kind of food eaten by humans living more than 10,000 years ago.

The scientists say that the human body has changed very little since humans first appeared on the earth, but the way we live has changed greatly. Our body has not been able to deal with (处理,对付)these changes in life style and this has led to new kinds of sicknesses. These new sicknesses were not known in ancient times, so they are called “ diseases of civilization”. Many cancers and diseases of the blood system, including heart attacks and strokes (中风) are examples of such diseases.

Scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little alcohol (酒精) or tobacco (烟草), probably none. Ancient people also got a great deal of physical exercise, but a change in food is one of the main differences between life in ancient times and that of today.

Stone-age people hunted wild animals for their meat, which had much less fat than domestic or tame ones (家畜). They also ate a lot of fresh wild vegetables and fruits. They didn’t have milk or any other dairy products, and they made very little use of grains. But today, we eat a large amount of these. We eat six times more salt than our remote ancestors (祖先). We eat more sugar. We eat twice as much fat but only one third as much protein (蛋白质) and much less vitamin C.

People today probably do not want to live the way people thousands of years ago did, but scientists say that we would be much healthier if we ate much the same way as remote ancestors did, cutting the amount of fatty, salty and sweet food.

1.According to the passage, people in industrialized nations would be much healthier if they ate___________.

A. more food than humans living 10,000 years ago did.

B. as much food as humans living 10,000 years ago did

C. more kinds of food eaten by people living over 10,000 years ago.

D. more of the same kind of food eaten by people over 10,000 years ago.

2.New kinds of sicknesses have been found because __________.

A. the human body has changed compared with humans who first appeared on the earth.

B. the way we live has changed a little.

C. our body can’t deal with the changes in life style.

D. the way we live today is proper for the human body.

3.What is the main cause that people suffer from a lot of new sicknesses?

A. Ancient people did a great deal of physical exercise.

B. People today have a lot of alcohol.

C. People today have more tobacco.

D. Food today is quite different from that of ancient times.

4.According to some scientists , Stone-age people were much healthier than people today because they ate a lot of _____________.

A. milk and other dairy products.　　 B. wild animals, fresh wild vegetables and fruits.

C. salt and sugar　　 D. grain foods

Australia and New Zealand’s health organizations have given their advice on when to use sunscreen (防晒霜), suggesting Australians apply it every day to avoid bad health effects.

A Sunscreen Summit took place in the Australian State of Queensland. During the summit, representatives from some of Australia’s leading research, medical and public health organizations examined the evidence on sunscreen use the determined that in most parts of the country it is beneficial to apply sunscreen every day.

“Up until now, public health organizations have recommended applying sunscreen ahead of planned outdoor activities but haven’t recommended applying it every day as part of a morning routine (惯例),” professor Rachel Neale from QIMR Berghofer Medical Research Institute said. “In recent years, it has become clear that the DNA damage causes skin cancer and melanoma (黑色素瘤), which is caused by repeated small exposure to sunlight over a period of time,” Neale said. “In Australia, we get a lot of sun exposure from everyday activities such as walking to the bus stop or train station,” Neale said.

A study showed that one in two Australians believed it was unhealthy and potentially dangerous to use sunscreen every day. However, Terry Slevin from the Public Health Association of Australia says it is wrong. “There is consistent and compelling evidence that sunscreens are safe,” Slevin said. “Importantly, medical trials have found that people who use sunscreen daily have the same levels of vitamin D as those who don’t,” Slevin added.

Australia has one of the highest rates of skin cancer in the world, which is made worse by the country’s close to Antarctica where there is a hole in the ozone layer (臭氧层), letting in higher numbers of UV rays.

1.What made Australian health organizations advise Australians to use sunscreen?

A.The makers of sunscreen.

B.Australian government.

C.The Sunscreen Summit.

D.New Zealand’s researchers.

2.What is not recommended before the Sunscreen Summit?

A.Using sunscreen as a morning routine.

B.Using sunscreen before outdoor activities.

C.Reducing the use of sunscreen.

D.Reducing outdoor activities.

3.What is the misunderstanding of many Australians?

A.Sunscreen will never take effect.

B.Sunscreen is bad for people’s health.

C.People using sunscreen have the same levels of vitamin.

D.D. People using sunscreen won’t have skin cancer.

4.Which of the following best explains “compelling” underlined in paragraph 4?

A.Interesting. B.Disappointing.

C.Boring. D.Convincing.
