A world in which extinct creatures could be brought back to life came a step closer yesterday. Australian scientists have managed to extract a gene from a preserved sample of a Tasmanian tiger and make it active. Thebreakthroughhas left them dreaming that one day they will be able to recreate the animal, which died out more than 70 years ago. And if it can be done with the Tasmanian tiger, it may also be possible to resurrect (复活) creatures that have been extinct for far longer.
“There used to be a time when extinction meant forever, but no more, ” said Professor Mike Archer. “We are now able to seriously challenge whether those animals that have gone for ever. What has been achieved is a very important step in bringing back those animals that are extinct. And while I think that technically it is still pretty difficult at the moment, we can now see the possibilities. I’m personally convinced that the Tasmanian tiger will be
brought back to life in my lifetime.”
The breakthrough came after nine years of experiments by scientists at the University of Melbourne, who extracted a gene from one of several tigers preserved in alcohol in a Melbourne museum. They removed the equivalent gene from a mouse embryo implanted the tiger gene and then watched as the mouse continued to grow normally, suggesting the tiger gene had been activated.
Team leader Dr. Andrew Pask said it was the first time DNA from an extinct species had been used to “induce (引起) a functional response in another living organism”.
However, the animal’s entire gene structure would have to be revived in the same way to even begin the possibility of bringing the Tasmanian tiger back from the dead.
Mick Mooney, a wildlife officer ofthe Tasmanian Government, was worried that such developments could encourage people’s indifference to the protection of endangered species.
“If people think that we can bring animals back to life after they’ve gone, they will start saying that there is nothing to worry about because we can fix it up later.”
4. What does the underlined word “breakthrough” in the l paragraph refer to?
A. Scientists have recreated new animals.
B. Scientists have resurrected endangered animal.
C. It has turned out that some creatures would not go extinct.
D. A tiger gene has been extracted successfully and activated.
5. Scientists are carrying out the experiments in order to ________.
A. bring extinct animals back to life
B. transplant the genes of tigers into other animals
C. find out what factors lead to the animals’ extinction
D. find a new way to extract animals’ DNA
6. Mike Archer thinks that ________.
A. scientists now have no technological difficulty reconnecting extinct animals
B. it’ll be a century or so before a Tasmanian tiger walks on the earth again
C. humans have come closer in reconnecting extinct animals
D. reconnecting extinct animals is impossible
7. We can learn from Mick Mooncy’s words that_________.
A. he thought it unnecessary to worry about endangered animals
B. his opinion is in contrast with that of the Tasmanian Government
C. he thought people should be encouraged to protect endangered animals
D. he is concerned that bringing extinct animals back to life may have a negative effect
C
New research has shown that loneliness may affect ants to a greater extent than many other living creatures.
It has long been known that loneliness can lead to a shorter life. In humans, it has even been found to be a driver of high blood pressure, sleep disorder, and depression that’s independent of factors like age, race, gender, weight and economic status.
However, loneliness has never been identified as a factor that can cut human lifespan by more than a small part of the average. Ants, on the other hand, appear to be far more sensitive to this stress, with loneliness leading to a surprising 91 percent reduction in lifespan.
That’s at least according to a study that details how “lonely” ants only live up to six days on average. Ants living in a community, on the other hand, were found to live up to about 66 days.
In a series of experiments where ants were picked from their colonies (群体) and separated, they were found to continuously walk without rest,consuming far more energy than they could ever.
The reason for the behavior is that an isolated ant is simple trying to get back to its colony at all costs, and doesn’t know what to do without its nest mates. After all, many entomologists (昆虫学家) would argue that an ant colony is far more a single living entity (实体) than its members.
If you were to take a single part from a clock, it would simply move aimlessly as well, running without a purpose. However, while there is a difference between aimlessness and loneliness, the researchers found that the latter affects lonely ants more directly.
The study indicated that ants can’t even eat alone, as they normally collect some of the food they gather in the field in a specialized organ called a crop.This crop is normally shared with other ants back at a nest,but as for a single ant, it simply just sits there, undigested and useless.
8. How does loneliness influence a person?
A. It can make him very tired of himself.
B. It can leave him in conflict with others.
C. It can lead to him being very independent.
D. It can cause him to suffer from poor health
9. What can be learned from the experiments?
A. Most ants can live about 6 days on average.
B. Lonely ants can become very restless.
C. Human beings are similar to ants in some way.
D. Lonely ants seem to be violent and impatient.
10. Why does an isolated ant walk non-stop?
A. It attempts to return to its colony.
B. It wants to attract other ants to form a colony.
C. It hopes to make signals to its mates.
D. It has to find more food to survive.
11. The author mentioned a clock in the passage_________.
A. to show ants have a biological clock in the head.
B. to prove ants are a well-regulated community.
C. to stress ants are really highly social animals.
D. to compare aimlessness with loneliness.
D
A new study has discovered that meditation (冥想) and oxygen sport together reduce depression. The Rutgers University study found that this mind and body combination, done twice a week for only two months,reduced the symptoms for a group of students by 40 percent.
“We are excited by the findings because we saw such a meaningful improvement in both clinically depressed and non-depressed students,” said lead author Dr. Brandon Alderman. “It is the first time that both of these two behavioral ways have been looked at together for dealing with depression.”
Researchers believe the two activities have an interactive effect on combatingdepression. Alderman and Dr. Tracey Shors discovered that a combination of mental and physical training (MAP) enabled students with major depressive disorder not to let problems or negative thoughts defeat them.
Rutgers researchers say those who participated in the study began with 30 minutes of focused attention meditation followed by 30 minutes of oxygen sport. They were told that if their thoughts drifted to the past or the future they should refocus on their breathing, enabling those with depression to accept moment-to-moment changes in attention.
Shors, who studies the productionof new brain cells in the hippocampus—part of the brain involved in memory and learning—says scientists have shown in animal models that oxygen sport exercise keeps a large
number of certain cells alive.
The idea for the human intervention (干预) came fromher laboratory studies, she says, with the main goal of helping individuals acquire new skills so that they can learn to recover from stressful life events.
By learning to focus their attention and exercise, people who are fighting depression can acquire new learning skills that can help them process information and reduce the overwhelming recollection of memories from the past, Shors says.
“We know these treatments can be practiced over a lifetime and that they will be effective in improving mental health.” said Alderman. “The good news is that this intervention can be practiced by anyone at any time and at no cost.”
12. What made the research so different?
A. Adopting a way of meaningful talk.
B. Combining the two behavioral ways to treat depression.
C. Treating depression with special medicine.
D. Comparing the depressed with the non-depressed.
13. The underlined word “combating” in Paragraph 3 can be replaced by ______.
A. fighting
B. identifying
C. distinguishing
D. examining
14. What did the participants do in the research?
A. They did oxygen sport half an hour before thinking.
B. They thought quietly and then took exercise.
C. They took exercise longer than they thought.
D. They took exercise while thinking quietly.
15. What is Shors’ main purpose of her studies?
A. To find out certain brain cells of humans.
B. To study the production of new brain cells.
C. To offer people a new method to treat stress.
D. To decide the links between stress and exercise.

How the smartphone affected teens
Some parents might worry about their teens spending so much time on their phones because it represents a complete departure from how they spent their own adolescence. But spending this much time on screens is not just different—in many ways, it’s actually worse.
Spending less time with friends means less time to develop social skills. A 2014 study found that sixth graders who spent just five days at a camp without using screens ended the time better at reading emotions on others’ faces, suggesting that teens’ screen-filled lives might cause their social skills to decline.
In addition, teens using smartphones read books, magazines and newspapers much less than previous generations did as teens: In the annual Monitoring the Future survey, the percentage of high school seniors who read a non-required book or magazine nearly every day dropped from 60 percent in 1980 to only 16 percent in 2015. College teachers tell me that students have more trouble reading longer text passages, and rarely read the required textbooks.
This isn’t to say that teens who use smartphones don’t have a lot going for them. They are physically safer and more tolerant than previous generations were. They also seem to have more realistic expectations than their parents did at the same age. But the smartphone threatens to disturb them before they even get started.
To be clear, moderate smartphone use—up to an hour a day—is not linked to mental health issues. However, most teens are on their phones much more than that.
Somewhat to my surprise, the teens I interviewed said they would rather see their friends in person than communicate with them using their phones. Parents used to worry about their teens spending too much time with their friends—they were a distraction, a bad influence, a waste of time. But it might be just what teens need.
