阅读短文,完成下列问题。

A

    When people first walked across the Bering Land Bridge thousands of years ago, dogs were by their sides, according to a study published in the journal Science.

    Robert Wayne of the University of California, Los Angeles, and Jennifer Leonard of the Smithsonian Institute, used DNA material—some of it unearthed by miners in Alaska—to conclude that today's domestic dog originated in Asia and accompanied the first humans to the New World about 10,000 to 15,000 years ago. Wayne suggests that man's best friend may have enabled the tough journey from Asia into North America. “Dogs may have been the reason people made it across the land bridge,” said Wayne. “They can pull things, carry things, defend you from fierce animals, and they're useful to eat.”

    Researchers have agreed that today's dog is the result of the domestication(驯化) of wolves thousands of years ago. Before this recent study, a common thought about the precise origin of North America's domestic dog was that Natives domesticated local wolves, the descendents(后代) of which now live with people in Alaska, Canada, and the Lower 48.

    Dog remains from a Fairbanks-area gold mine helped the scientists reach their conclusion. Leonard, an evolutionary biologist, collected DNA from 11 bones of ancient dogs that were locked in permafrost(永冻层) until Fairbanks miners uncovered them in the 1920s. The miners donated the preserved bones to the American Museum of Natural History in New York City, where they remained untouched for more than 70 years. After borrowing the bones from the museum, Leonard and her colleagues used radiocarbon techniques to find the age of the Alaska dogs. They found the dogs all lived between the years of 1450 and 1675 A.D., before Vitus Bering and Aleksey Chirikov who were the first known Europeans to view Alaska in 1741. The bones of dogs that wandered the Fairbanks area centuries ago should therefore be the remains of “pure native American dogs,” Leonard said. The DNA of the Fairbanks dogs would also expose whether they were the descendents of wolves from North America.

    Along with the Fairbanks samples, the researchers collected DNA from bones of 37 dog specimens(标本) from Mexico, Peru, and Bolivia that existed before the arrival of Columbus. In the case of both the Alaska dogs and the dogs from Latin America, the researchers found that they shared the most genetic material with gray wolves of Europe and Asia. This supports the idea of domestic dogs entering the New World with the first human explorers who wandered east over the land bridge.

    Leonard and Wayne's study suggests that dogs joined the first humans that made the adventure across the Bering Land Bridge to slowly populate the Americas. Wayne thinks the dogs that made the trip must have provided some excellent service to their human companions or they would not have been brought along. “Dogs must have been useful because they were expensive to keep,” Wayne said. “They didn't feed on mice; they fed on meat, which was a very guarded resource.”

(1)、The underlined word “remains” is closed in meaning to ______.

A、leftover food B、animal waste C、dead bodies D、living environment
(2)、According to the study described in Paragraph 4, we can learn that ______.

A、ancient dogs entered North America between 1450 and 1675 AD B、the 11 bones of ancient dogs are not from native American dogs C、the bones discovered by the gold miners were from North American wolves D、the bones studied were not from dogs brought into North America by Europeans
(3)、What can we know from the passage?

A、Native Americans domesticated local wolves into dogs. B、Scientists discovered some ancient dog remains in 1920s. C、Latin America's dogs are different from North America's in genes. D、Ancient dogs entered North America across the Bering Land Bridge.
(4)、The first humans into the New World brought dogs along with them because ______.

A、dogs fed on mice B、dogs were easy to keep C、dogs helped protect their resources D、dogs could provide excellent service
(5)、What does the passage mainly talk about ______.

A、the origin of the North American dogs B、the DNA study of ancient dogs in America C、the reasons why early people entered America D、the difference between Asian and American dogs

Jorg Muller, an enologist at the University of Würzburg, with his colleagues, proposes a way to measure the biodiversity—listen to the jungle by AI, in a paper published in Nature Communications.

The rainforests are very important and always alive with the sounds of animals, which is useful to ecologists. When it comes to measuring the biodiversity of a piece of land,listening out for animal caller is more effective than uncovering the bushes looking for tracks and pa w prints. The latter analysis method is time-consuming, and it requires an expert pair of ears. Muller's idea was to apply the principle of smartphone apps which can identify the sounds of birds, bats and mammals to conservation work.

The researchers took recordings from across 43 sites in the rainforests. Some sites were relatively primitive, old-growth forests. Others were areas that had just been cleared for pasture(牧场) recently. And some other original forests had been cleared but then abandoned, allowing themselves to regrow. The various calls were identified by an expert,and then used to construct a list of the species present. As expected, the longer the land had been free from agricultural activity, the greater biodiversity it hosted. Then it was the computer's turn. "We found that the AI tools could identıly the sounds as well as the experts," says Dr. Muller.

Of course, not everything in a rainforest makes a noise. Dr. Muller and his colleagues used light traps to catch night-flying insects, and DNA analysis to identify them. They found that the diversity of noisy animals was a reliable representative for the diversity of the quieter ones, too.

Besides measuring the biodiversity, the results are also expected to be applied to outside ecology departments. Under pressure from their customers, firms like L'Oreal, a make-up company, and Shell, an oil firm, have been spending money on forest restoration projects around the world. Dr. Muller hopes that an automated approach to checking on the results could help monitor such efforts, and give a standard way to measure whether they are working as well as their sponsors say.

We're often told "laughter is the best medicine".Laughter is ancient and instinctual,and a fundamental part of everyday life—something most of us enjoy naturally.There are comedy channels on TV,comedy festivals and our favorite funny friend who's sure to get our giggle on.

So why do we need laughter experts?Surely they're for people who can't laugh for whatever reason.However,while the ability to laugh is innate,the decision to activate and use it to its full ability is a choice.

When life gets stressful;illness creeps in;relationships are put to the test or we're struggling financially,there's rarely much to laugh about.So,we don't.Yet turning into the lighter,more humorous side of life,and activating one's "laughter self" is critical to mental health.Rather than waiting for something funny to happen or for life to be a bed of roses,we can transform our emotional state by tapping into our laughter and humor resources.This helps create distance between us and our pain and improve our moods and resilience(恢复力) to stress.It provides relief and release from some of the stress that has embedded in our bodies and minds,freeing ourselves to power forward,even a little.

Ironically,because laughter is an innate and largely unconscious behavior,it's rarely given much thought.As it's seldom thought about,it can't be that important.

Wrong.If laughing is a more complex behavior,my belief is people will pay greater honor to it,rather than something to laugh off.It's actually one of the most complicated things our bodies process.It is a vocal means of communication before language forms and the brain has fully developed.The vast majority of us maintain the ability to laugh until our final curtain falls,even amid declining cognitive function.

Turning toward the healing power of humor and laughter assists with personal and professional resilience,performance and overall well-being.No joke.

According to a new research,the more people in a country who have a particular gene(基因),the happier the nation will be.This DNA is known as the FAAH gene.People with a particular version of it tend to be cheerier souls.There is a link between levels of the FAAH gene and the number of people who say they are very happy.

Sweden—one of the happiest countries in the world—also has lots of happy DNA.Ghana,Nigeria,Mexico and Columbia all come out near the top in the happiness league,and have high rates of the gene.In contrast,the people of Iraq,Jordan and China are among the least likely to rate themselves as very happy and also have the lowest level of the FAAH gene.

However,wealth and health are found to have little effect on happiness.The finding could help explain why some of the world's poorest nations are also the happiest.In addition,the FAAH gene and an optimistic attitude would not always go hand in hand.For example,Russians and Estonians score very low in happiness,despite having the right happy DNA.

Professor Michael Minkov said,"The climate condition is associated with the nation's happiness.We can notice the high occurrence of the FAAH gene in tropical(热带的) areas in the Americas and Africa.And the occurrence of the gene around the Mediterranean Sea is much lower than that in Northern Europe."

The social experts say that genetics is not the only determinant(决定因素) of happiness.The economic and political difficulties in some nations also contribute to the very low happiness scores.Nations that are not blessed with the right DNA aren't necessarily miserable.

More than 400 athletes across a variety of sports, ages and levels of experience were questioned for the study by sports psychology experts from Staffordshire University and Manchester Metropolitan University. The findings reveal that athletes' belief systems—specifically irrational(非理性) beliefs—are related to poorer self-confidence, and in turn, greater competitive anxiety and depressive symptoms.

"Phrases that reflect self-depreciating(贬低) beliefs such as 'If I lose, I'm a failure' or 'If I face setbacks, it shows how stupid I am' are warning signs," said the authors. Paul Mansell, Lecturer in Sport and Exercise Psychology at Staffordshire University, said, "Despite the psychological benefits of physical activity, studies frequently report poor mental health in athletes, which may be exacerbated by adversities, such as injury, de-selection, and performance pressure. We investigated athletes' beliefs, how they view stress, their levels of self-confidence and put all this data together to work out what might predict psychological well-being. We found irrational beliefs to be a core reason for symptoms of poor mental health in athletes."

This is the first known study that has examined irrational beliefs, self-confidence, and the psychological well-being of athletes all together. Irrational beliefs are extreme, rigid, and illogical ideas that people hold. For example, a person might believe that they "must" get what they want, or that just because they have failed, they are a "complete failure".

"We can all work to help athletes develop mindsets that help them deal with the challenges of sport and life. By encouraging rational and logical beliefs about performance, we can help athletes to stay healthy amidst the high demands of competitive sport," said Paul Mansell.

The author s propose Rational Emotive Behavior Therapy(REBT) as an effective tool for protecting self-confidence. REBT helps athletes to challenge these self-depreciating beliefs and develop beliefs that are more helpful and healthy. For example, rather than believe "I am a failure if I fail", this might be countered with "Failing is not ideal, but it does not mean that I am a failure".

 阅读下列短文,从每题所给的A、B、C和D四个选项中,选出最佳选项。

"Having the world at our fingertips" is a metaphor often used when we put our hands on information technology, like smartphones and computers. This is a good metaphor. But what is much better is how we use our hands to make things done.

Put one hand flat on a surface, palm down, and you might be able to make out the outline of 14 short bones in your thumb and fingers, in addition to 5 longer ones in your palm that are jointed to your wrist. These bones give each hand its rigid, knuckled structure. Together they're critical components of the anatomical (解剖的) architecture that allows your hand to move. At each of your fingertips there's an ever-growing, translucent plate of fibrous protein, otherwise known as a nail. Although they're nice for decoration, your nails protect and enhance your sensitivity to touch, too.

Imagine squeezing a piece of paper between your thumb and index finger, for example. We use this type of forceful pad-to-pad precision grasping without thinking about it, and literally in no time. Yet it was a breakthrough in human evolution. Other primates (灵长目动物) exhibit some kinds of precision grasps in the handling and use of objects, but not with the kind of efficiency that our hand does.

With a unique combination of traits, the human hand shaped history. No question, stone tools couldn't have become a keystone of human technology without hands that could do the job, along with a nervous (神经的) system that could regulate and coordinate the necessary signals. Even for those who have never attempted to make a spear tip or arrowhead from a rock, it's obvious that it would require strong grasps, constant rotation and repositioning, careful strikes with another hard object. And even for those who have done so, it can be a bloody business.

Of course, the most common object that people touch nowadays is a screen. And the tap-tap-tap movement of our fingers is a unique human ability, as no other primate can move their fingers as rapidly and independently as we do. Here again, we can thank the extraordinary human brain given that normal finger tapping requires the functional integrity of different parts of our central nervous system.

 根据短文内容,从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。

Lying awake for hours before falling asleep is a common problem. Even if you can finally fall asleep, taking too long to fall asleep can lead to too few hours of sleep altogether. {#blank#}1{#/blank#} So people having trouble falling asleep always wonder how they can sleep well. 

Parents know from experience that gentle music can help babies fall asleep. Science supports this, showing that children of all ages, from babies to elementary school children, sleep better after listening to comfortable music. Fortunately, children aren't the only ones who can benefit from gentle music before bedtime. {#blank#}2{#/blank#}

Listening to music likely improves sleep for more than one reason. Music can promote sleep directly by affecting your physiology (生理机能). {#blank#}3{#/blank#}Besides, it can also promote sleep by becoming a healthy bedtime habit. Many people can't fall asleep quickly because stressful and worrying thoughts keep them awake at night. By listening to music, the mind has something else to focus on. With time, the practice of listening to music at bedtime becomes more effective as the brain positively associates music with sleep. 

{#blank#}4{#/blank#} Studies have looked at many types of music and playlists but there isn't a clear answer about the best music for sleep. What we do know is that researchers have typically used either a self-made playlist or one that has been designed especially with sleep in mind. One of the most important things on how music affects a person's body is their own musical preferences. {#blank#}5{#/blank#} For those who don't want to design their own playlist, online music services have stepped in and usually offer playlists for sleep or relaxation.

A.It can guarantee sufficient sleep.

B.It's natural to wonder about the best type of music for sleep.

C.The quality and quantity of our sleep become poor as we age.

D.Listening to music can reduce your stress and inspire positive feelings.

E.This can have a serious effect on a person's quality of life if it continues.

F.People across age groups report better sleep quality after listening to soft music.

G.Useful personal playlists may include relaxing songs that have helped with sleep in the past.
