Scientists have recently discovered a major habitat where live more than 1.5 million Adelie penguins(企鹅）near the Antarctic Peninsula. Based on direct ground counts and computer counts, the researchers found a total of 751,527 pairs of Adelie penguins on the Danger Islands in the Weddell Sea on the east side of the Antarctic Peninsula. The Adelie penguins discovered here is more than the rest in the other places of Antarctic Peninsula, which was published in the journal Scientific Reports.
Moreover, the number represents the first complete census of Adelie penguins in the Danger Islands, the researchers added. “Until recently, the Danger Islands wasn't known to be an important penguin habitat.” Heather Lynch, an ecologist from Stony Brook University who led the study, said, “These super habitats have gone undiscovered for decades partly because the islands themselves are distant and the dangerous waters that surround them.” The Danger Islands appears to have avoided recent loss in penguin population documented on other parts of the Antarctic Peninsula.
Another study published earlier suggested that more than 70 percent of king penguins may disappear by the end of the century as a result of global warming and overfishing. As the Danger Islands is likely to remain important islands for many penguins under climate change, scientists believe it deserves special consideration in the design of Marine Protected Areas in this area. “Now that we know how important this area is for penguin, we can better move forward designing Marine Protected Areas and managing the fishery,” said Lynch.
The idea of building the Marine Protected Areas, which covers 1.8 million square km of the Weddell Sea and around the Antarctic Peninsula, was first put forward by the European Union and supported by nongovernmental organization Greenpeace. In January, a global campaign has been started in the vast fishing-free zone to better protect wildlife.

Exercise is known to benefit people’s mental health, but scientists recently discovered that too much exercise may have a negative effect on it.
The researchers studied about 1.2 million people in the United States in 2013, 2015 and 2017. The participants, on average, experienced 3, 4 days of poor mental health each month. Those who did exercise experienced 1, 5 fewer days of poor mental health per month, compared to those who didn’t exercise at all. The team found that people who exercised for 30 to 60 minutes three to five times a week had the best mental health, but those who exercised for more than three hours had worse mental health than those who didn’t exercise at all.
The scientists think that people who exercise so much may experience poorer mental health because that much exercise can be a sign of obsessive (强迫症患者) behaviors that have been associated with poor emotional and psychological outcomes. However, the only mental health disorder that the researchers looked at was depression.
Among those who had been diagnosed with depression, people who did exercise experienced 3.75 fewer negative mental health days than those who did not, showing an ever greater difference, According to the Centers for Disease Control and Prevention. 7, 6 percent of people in the U.S. age 12 and over have depression. While all types of exercise appeared to help with mental health, cycling, gym-based exercise and team sports were the most beneficial.
The team also looked at more specific factors, like education. People with a college education reported 17.8 percent fewer days of poor mental health than those without that level education Additionally, people in a healthy BMI (体重指数) range reported a 4 percent reduction in poor mental health days thin those whose BMIs were high. Even salary was a factor: compared to people with bower salaries, those with higher salaries experienced a 17 percent reduction in poor mental health days.
The study showed that exercise can help with mental health, but that in some cases, limiting it may be necessary.
1.What did the study find?
A. People should do exercise three to five times a month.
B. Too much exercise may affect people’s mental health.
C. The more exercise people do, the healthier body they have.
D. People who do exercise have problems in mental health.
2.Which of the following sports benefits people s mental health most according to the text?
A. Skiing. B. Football.
C. Mountain climbing. D. Motorcycle racing.
3.How many factors that affect mental health are mentioned in the text?
A. Two. B. Three.
C. Five. D. Four.
4.What can we infer from the text?
A. We must reduce our time of doing regular exercise.
B. Most American children have mental health problems.
C. Doing exercise reasonably is beneficial to relieving depression.
D. The men who don’t do exercise have the worst mental health.

Now scientists have discovered the first evidence that the animals actually behave like their masters. Just like children, they adopt a “look and learn” approach which means they can mimic (模仿) human's actions when going about their tasks.
Biologists and psychologists at the universities of Vienna and Oxford designed an experiment to test the theory that dogs do have the ability to copy what they see, using a simple wooden box. In the study, ten owners showed their dogs how to open the wooden box, sometimes using their heads to push a handle and sometimes using their hands.
In the first part of the test, five dogs were rewarded with a piece of sausage for copying their owners' actions. The other five were rewarded with food for not copying, and using other methods. With each dog the experiment was repeated hundreds of times, and the time taken for a dog to get it “right” on 85 percent of attempts (17 goes out of 20) was recorded. The dogs encouraged to mirror their owners reached this point almost three times sooner on average than those rewarded for not copying them. In the second part of the test, all the dogs were only rewarded for copying the method their owners used. The five dogs previously rewarded for copying their owners reached the 85 percent mark more than twice as the other five.
In a paper published in Proceeding of the Royal Society, they concluded, “Like humans, dogs can't help imitating actions they see.” Going further, they said, “The results suggest the imitative (模仿的) behavior of dogs is shaped more by their developmental interactions with humans than by their evolutionary (进化的) history of domestication (驯化).”
Caroline Kisko, from the Kennel club, said, “A dog's behavior is influenced much like that of a child learning right from wrong and adopting similar patterns of behavior. We hope that owners understand the importance of their actions and use this knowledge to set good examples and therefore positively influence the behavior of their pets.”

On Tuesday, scientists announced that they have discovered the bones of four settlers in Jamestown, Virginia. Jamestown was the first permanent English settlement in what become the United States. The bones were unearthed under the floor of a Jamestown church which was discovered in 2010 and is considered as America，s first Protestant church.
The Jamestown Rediscovery Foundation at Historic Jamestowne and the Smithsonian's Museum of Natural History announced that the settlers held high leadership positions. The men, Rev.Robert Hunt,Capt. Gabriel Archer,Sir Ferdinando Wainman,and Capt. William West, all played a role in the Jamestown settlement. After being lost to history for more than 400 years, the discovery of their remains provides new clues about their life and the importance of religion in the 1600s.
“This is a very important discovery,” Jamestown Rediscovery Foundation President James Horn said in a statement. “These men were among the first founders of English America."
About 100 people settled along the James River in what would become the first English settlement m 1607. During that time, settlers in Jamestown were faced with famine and disease The colony was nearly wiped out due to conflict with Native Americans in the area and with other English settlers.
"They lived and died at a hard time in the history of the settlement , when Jamestown almost ended in failure," Horn said. “The bones of these men help fill in the stories of their lives ”
The Smithsonian and the Rediscovery Foundation found the remains in November of 2013. Scientists used 3-D technology to locate the exact gravesites of the men. The team wanted to identify its findings before announcing the discovery. They identified the men using historical records and studied the chemicals of the bones to learn what the men ate and where they came from.
Findings from the burials will go on display within weeks at Historic Jamestowne. The site also plans to honor the men and will keep their bones in a safe place for future study.
1.The bones found in a Jamestown church_____________.
A. were first discovered in 2010
B. have been buried for over four centuries
C. have proved to be a family of four
D. are complete and easy to recognize
2.The underlined phrase ‘wiped out” in Paragraph 4 is closest in meaning to ______________.
A. supported fully B. developed rapidly
C. destroyed completely D. protected successfully

British scientists have discovered the willow trees planted at an angle could increase sugars for biofuel production.
Willow is a fast-growing species. It is already used to produce fuels for the renewable heating and power market. In future it could also help to produce biofuel to power vehicles. It has been known that when willows growing in the wild are blown sideways, they tend to produce more sugars. But for a while it has not been known why this happens.
Researchers at Imperial College London, led by Dr Nicholas Brereton and Dr Michael Ray of the Department of Life Sciences, have now solved the mystery. When the tree is blown sideways, its genes (基因) produce large numbers of sugar molecules (分子) to straighten the tree upwards.
“This is an important breakthrough. Our study now shows that natural genetic changes are related to these differences. And this could well be the key to unlocking the future for green energy from willow,” said Dr Brereton.
The research was carried out under lab conditions. The willows were grown at an angle of 45 degrees. They were compared to willows which grow naturally straight upwards. The team then looked for the same effect among the willows growing on the Isle of Orkney where strong winds cause the trees to bend at extreme angles. They discovered that the Orkney trees produce five times the amount of sugars found in willows grown in sheltered conditions.
Willow is widely planted across the UK. The results show that biofuel crops such as willows could be grown in climatically changeable conditions where chances of growing food crops are limited.
The study is published in Biotechnology for Biofuels.
1.What may happen when willows are planted in strong winds?
A. They stop growing. B. Few sugars are produced.
C. They try to grow sideways. D. Changes in genes take place.
2.The Orkney willows ________.
A. are unusually rich in sugars B. grow naturally straight upward
C. look taller than ordinary willows D. are stronger than those growing in labs
3.Farmers living in changeable climate _______.
A. use biofuel for heating and power B. are encouraged to grow biofuel crops
C. can plant different kinds of food crops D. should make their willows grow straight
4.Where does this passage most probably come from?
A. A personal diary. B. A travel magazine.
C. A scientific journal. D. A newspaper advertisement.

The fact that ants are fascinating insects has been known for some time. Now, scientists have discovered a large number of wood ants living in an abandoned underground storehouse in Templewo, Poland, despite having no obvious source of food.
Polish zoologist Wojciech Czechowski and his team began studying the underground colony in 2013. They found the ants built a 60-cm high nest in the soil directly over the storehouse vertical air pipe. As years passed, the metal covering on the pipe eroded, leaving behind a hole that thousands of worker ants accidentally slip into each day as they go about their daily chores. The scientists say that there are no sources of food in the storehouse. This means that the insects live in a state of near starvation.
In July 2015, the researchers disturbed part of the ant nest in search of larvae (幼虫), cocoons(茧), and queens. They found nothing, leading them to suspect that the lack of food and cold temperatures made reproduction impossible and that the group tending the nest is entirely made up of non-reproductive female workers. Their population is refilled every year, by a new rain of unfortunate ants that slide down the hole. The researchers say that when they returned in January 2016, the nest had been repaired. It appears that despite the terrible conditions, the worker ants do not stop constructing their nest.
Wood ants are known for their ability to adapt to bad living conditions. In this case, the millions of worker ants trapped in the storehouse have no choice. But instead of losing hope, they are making the best of the situation—a classic example of “when life gives you lesions make lemonade.”
1.How did the wood ants arrive in the storehouse?
A. They fell down there by accident.
B. The research team brought them there.
C. The storehouse builders left them there.
D. They were attracted by the environment.
2.What does the underlined word “eroded” in Paragraph 2 probably mean?
A. Expanded. B. Rotted.
C. Exploded. D. Melted.
3.What did the researchers find in the nest?
A. Larvae. B. Cocoons.
C. A queen. D. Worker ants.
4.Why did the population of wood ants remain steady?
A. They had enough food.
B. They were able to reproduce.
C. They adapted to the conditions.
D. They had new comers to join them.
