1 . In a recent series of experiments at the University of California, researchers studied toddlers’ thinking about winners and losers, bullies (欺凌) and victims.

In the first experiment, toddlers (学步儿童) watched a scene in which two puppets (木偶) had conflicting goals: One was crossing a stage from right to left, and the other from left to right. The puppets met in the middle and stopped. Eventually one puppet bowed down and moved aside, letting the other one pass by. Then researchers asked the toddlers which puppet they liked. The result: 20 out of 23 toddlers picked the higher-status puppet — the one that did not bow or move aside. It seems that individuals can gain status for being dominant (占优势的) and toddlers like winners better than losers.

But then researchers had another question: Do toddlers like winners no matter how they win? So, researchers did another experiment very similar to the one described above. But this time, the conflict ended because one puppet knocked the other down and out of the way. Now when the toddlers were asked who they liked, the results were different: Only 4 out of 23 children liked the winner.

These data suggest that children already love a winner by the age of 21-31 months. This does not necessarily mean that the preference is inborn: 21 months is enough time to learn a lot of things. But if a preference for winners is something we learn, we appear to learn it quite early.

Even more interesting, the preference for winners is not absolute. Children in our study did not like a winner who knocked a competitor down. This suggests that already by the age of 21-31 months, children’s liking for winners is balanced with other social concerns, including perhaps a general preference for nice or helpful people over aggressive ones.

In a time when the news is full of stories of public figures who celebrate winning at all costs, these results give us much confidence. Humans understand dominance, but we also expect strong individuals to guide, protect and help others. This feels like good news.

3 . Ecology is a complicated thing. Given the facts that elephant damage often kills trees and bush fires often kill trees, it would be________to assume that a combination of the two would make things worse. Contrary to this assumption, ________, as the recently-published research by Benjamin Wigley shows, if a tree has already been damaged, fire can________help to make things better.

One common way in which elephants harm trees is by stripping(剥) them of their bark(树皮). Dr Wigley, who did indeed start from the obvious________, set off to find out how much worse bush fires would make the effects of this bark stripping. To serve this purpose, he set up a study in the Kruger National Park. Since 1954, the Kruger has been the site of experiments in which plots of land have been burned________, to understand the effects of fire on plain ecology. In these experiments, Dr Wigley looked at trees in three different zones, in one of which, the trees were burned every year; in the second, they were burned every other year, while the third zone, by contrast, was actively________fire. To keep things consistent, he looked at the fate of the same tree species, the marula(马鲁拉树), in all three zones. He picked marulas because they are particular________of elephant activity. Their fruit are delicious, and prized by elephants and people alike. But elephants also seem to enjoy eating their bark. In July 2016 he and his colleagues identified 20 marulas in every zone and used special tools to________from each of them a circular section of bark 5 cm in diameter. Having imposed this damage, they________the wounds over the course of the following two years, to see what would happen. To their________, they discovered that the wounds of trees in fire zones recovered far better than those of trees that had seen no fires at all. Wounded trees in the annual burn zone re-grew 98% of their lost________during the two years of the study. Those living in the biennial(两年一次的) burn zone re-grew 92% of it. But those in the zone where fires were________re-grew only 72%.

The researchers also found something else when they were measuring the trees’ wounds: ants. Ten of the 20 trees in the fire-prevention zone developed ant colonies in their wounds. The ants in question were a species that is known to damage trees and is supposed to________tissue healing. By contrast, only five trees in the biennial burn zone and three in the annual zone developed ants’ nests in their wounds. It looks, therefore, as if bush fires are treating trees’ wounds by killing ants that might________colonize and damage them. Though such fires are surely harmful to healthy trees, it seems, in an example of two negatives making a positive, as if they are actually________to sick ones.

5 . A robot created by Washington State University (WSU) scientists could help elderly people with dementia (痴呆) and other limitations live independently in their own homes.

The Robot Activity Support System, or RAS, uses sensors installed in a WSU smart home to determine where its residents are, what they are doing and when they need assistance with daily activities. It navigates (定位) through rooms and around obstacles to find people on its own, provides video instructions on how to do simple tasks and can even lead its owner to objects like their medication or a snack in the kitchen.

“RAS combines the convenience of a mobile robot with the activity detection technology of a WSU smart home to provide assistance in the moment, as the need for help is detected,” said Bryan Minor, a postdoctoral researcher in the WSU School of Electrical Engineering and Computer Science.

Currently, an estimated 50 percent of adults over the age of 85 need assistance with every day activities such as preparing meals and taking medication and the annual cost for this assistance in the US is nearly $2 trillion. With the number of adults over 85 expected to triple by 2050, researchers hope that technologies like RAS and the WSU smart home will relieve some of the financial strain on the healthcare system by making it easier for older adults to live alone.

RAS is the first robot researchers have tried to incorporate into their smart home environment. They recently published a study in the journal Cognitive Systems Research that demonstrates how RAS could make life easier for older adults struggling to live independently.

“While we are still in an early stage of development, our initial results with RAS have been promising,” Minor said. “The next step in the research will be to test RAS’ performance with a group of older adults to get a better idea of what prompts, video reminders and other preferences they have regarding the robot.”

1. How does RAS serve elderly people?

A．Through sensors.	B．Through objects.
C．Through a mobile robot.	D．Through their daily activities.

2. What can we know about RAS?

A．It is the first robot used in daily life.	B．Its function remains to be tested.
C．It can locate people and do any task.	D．It can cook for owners on its own.

3. What’s Minor’s attitude toward the future of RAS?

A．Doubtful.	B．Negative.
C．Optimistic.	D．Uncertain.

4. What can be a suitable title for the text?

A．Elderly people leave the nursing home.

B．Smart Home Tests first elder-Care robot.

C．RAS, the first robot to make home smart.

D．Older adults have benefited from RAS.

6 . It’s late in the evening, time to close the book and turn off the computer. You’re done for the day. What you may not realize, however, is that the learning process actually continues in your dreams.

It might sound like science fiction, but researchers are increasingly focusing on the relationship between the knowledge and skills our brains absorb during the day and the often strange imaginings they generate at night. Scientists have found that dreaming about a task we’ve learned improves performance in that activity (suggesting that there’s some truth to the popular idea that we’re “getting” a foreign language once we begin dreaming in it). What’s more, dreaming may be an essential part of understanding, organizing and retaining what we learn.

While we sleep, research indicates, the brain replays the patterns of activity it experienced during waking hours, allowing us to enter what one psychologist calls a neural (神经的) virtual reality. A vivid example of such replay can be seen in a video researchers made recently about sleep disorders. They taught a series of dance moves to patients suffering from sleepwalking and related conditions. They then videotaped the subjects as they slept. Lying in bed, eyes closed, one female patient on the tape performs the dance moves she learned earlier.

This shows that while our bodies are at rest, our brains are drawing what’s important from the information and events we’ve recently encountered, then integrating that material into the vast store of what we already know. In a 2010 study, researchers reported that college students who dreamed about a computer maze (迷宫) task they had learned showed a 10-fold improvement in their ability to find their way through the maze compared with participants who did not dream about the task.

That study’s chief researcher Herbert Smith suggested that studying right before bedtime or taking a nap following a study session in the afternoon might increase the probability of dreaming about the material. Think about that as you go to sleep tonight.

1. What happens when one enters a dream state?

A．The body continues to act as if the sleeper were awake.

B．The neural activity of the brain will become intensified.

C．The brain once again experiences the learning activities of the day.

D．The brain behaves as if it were playing a virtual reality video game.

2. What does the brain do while we are sleeping?

A．It replaces old information with new material.

B．It processes and absorbs newly acquired information.

C．It regroups information and places it in different files.

D．It systematizes all the information collected during the day.

3. How can learning be enhanced according to Herbert Smith?

A．Staying up late before finally going to bed.

B．Having a period of sleep right after studying.

C．Having a dream about anything you are interested in.

D．Thinking about the chances of dreaming about the material.

4. What is the research discussed in the passage mainly about?

A．How study affects people’s dreams.

B．Why people learn more after sleeping.

C．What time students should study and sleep.

D．How dreaming may lead to improved learning outcomes.

7 . In the Fake News Era, Building Trust with Consumers Is Crucial

With consumers growing increasingly frustrated with online advertising and privacy concerns, how to you convince shoppers to buy your narrative（叙述）, let alone your product?

A recent report by Trust-Radius, a software review company that connects buyers and vendors（供应商）, may be able to shed some light. Among other interesting findings, it turns out that it may actually benefit brands to be painfully _____ about their products.

Consumer awareness of influencer marketing tactics（策略）is increasing. _____   according to the report, most consumers trust online peer _____ as much as recommendations from friends -- and well above company advertising message. Feedback from everyday folks, it seems, actually carries more _____ than a brand ambassador （大使）from an out-of-reach personality.

Transparency（透明度）is crucial. The report found that there is a large trust _____ between vendors and buyers. While vendors believe they are transparent, most buyers don’t appear to see it. During the sales process, for example, 85 percent of vendors -- _____ to be open about their product’s limitations during the sales process -- but   only 36 percent of buyers share that same view. The reality is, consumers don’t expect any products to be _____ -- they just want to enter relationships with their eyes wide open so that they can _____ the options that are best for   them. They also want brands to be more _____. 66 percent of consumers say they will leave a company if they feel they are being treated like a number and not an individual.

Along with the combination of take news, advertising fraud, and data leaks, there have been fake reviews as well. Review sites have been _____ giving preferential（优惠的）treatment to paid advertisers, and consumers are increasingly discerning（有辨别力的）, as a result. _____, review sites are not our only source of peer reviews, with social media providing customer experiences on a second - to - second basis. When brands treat every _____ with a customer as a potential review, they’ll start paying more attention to detail, and being alert to delivering a valued and memorable experience every time. Taking feedback seriously also lets current customers feel valued and respected and makes your business seem more approachable. This helps secure _____, and often, these customers   will become brand ambassadors to their friends, family and people they meet online.

The challenge for brands today is determining how to use the _____ of the consumer to their advantage. In an age of cutting - edge technology, artificial intelligence, and self-service customer care, it’s odd to acknowledge that the best way to build trust with your customers is by holding an open _____ with your customers. Being more human, transparent, and listening to what people are saying will see your company thrive in an era marked by consumer suspicion.

8 . 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。

"Pick up the pace!" said Amy's husband. "But I can't!" Amy said, her heart beating quickly inside. "I can't go any faster! Her husband encouraged her. "Yes, you can! You're making progress every day.”

To help Amy stay healthy, her husband had been running with her for over two years. Several years ago, Amy could barely walk down the stairs of her apartment building due to fatness caused by eating disorders. She realized the problem after a failed job interview and began walking to improve her ability to move. At first, she could walk for only 15 minutes at a time. But she pushed herself every day, walking 5 minutes longer than she did the day before until she walked for an hour and eventually two. For three years, Amy kept her walking habit, slowly and painstakingly building her body shape. Then she changed her walking shoes to running shoes about two years ago and became an excellent runner.

In March 2001, an advertisement invited people to nominate（提名）an ordinary person who inspired them to bring the Olympic flame to Salt Lake City as torch bearers（火炬手）or support runners.（Support runners serve as “guardians of the flame" and run with torch bearers along the journey.）Amy's experiences touched her husband, so he nominated her to be a torch bearer. The possibility to be selected was low, but Amy wanted to try.

Running taught Amy the importance of training for a race. She pictured herself running a race and crossing the finish line. For months, she ran through her neighborhood carrying a broken-off broom handle, feeling the weight of the torch. She waved at her neighbors, pretending they were cheering crowds. She also printed a picture of a torch bearer wearing the white uniform, replaced the face with a picture of hers, and put it onto her refrigerator door.

Every day, Amy imagined herself as a torch bearer. She was training for a historic running event. On September 26th, while on her daily run through her neighborhood, an express package arrived.

10 . 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。

The easy way out isn't always easiest. I learned that lesson when I decided to treat my father to a special meal. I glanced through the cookbook and chose a menu which included homemade bread. Knowing the bread would take time, I started on it as soon as he left for work.   

As I was not experienced in cooking, I thought if a dozen was good, two dozen would be better, so I doubled everything. As Dad loved oranges, I also opened a can of orange and poured it all into the bowl. Soon there was sticky dough (面团) covered with ugly yellowish marks. Realizing I had been defeated, I put the dough in the rubbish bin outside so I wouldn't have to face him laughing at my work.

I went on preparing the rest of the meal, and, when Dad got home, we sat down to Cornish chicken with rice. He tried to enjoy the meal but seemed disturbed. Twice he got up and went outside, saying he thought he heard a noise. The third time he left, I went to the windows to see what he was doing.   

Looking out, I saw Dad standing about three feet from the rubbish bin, holding the lid up with a stick and looking into the container. When I came out of the house, he dropped the stick and explained that there was something alive in the rubbish bin. Picking up the stick again, he held the lid up enough for me to see. I felt cold. But I stepped closer and looked harder.   

Without doubt it was my work. The hot sun had caused the dough to double in size and the. fermenting yeast (酵母) made the surface shake and sigh as though it were breathing. I had to admit what the "living thing" was and why it was there. I don't know who was more embarrassed by the whole thing, Dad or me.
