As artificial intelligence products steadily improve at pretending to be human, people will increasingly be put in the unsettling situation of not knowing     1     they are talking to a machine. But the     2     (true) may make such products less effective: recent research finds a trade-off between transparency and cooperation in human-computer interactions.

The study used a game in     3     paired players made a series of     4     (decision) to cooperate with betray their partner. In     5     long run, it pays for both to keep cooperating. But there is always the desire     6    (earn) extra points at the partner’s expense. Previous work suggested people tended to distrust machines, so the scientists hoped people     7     (play) with a known robot would recognize its ability to cooperate and would     8     (eventual) get past their distrust.

“Sadly, we failed at this goal,” says Talal Rahwan, a senior author on the paper,     9     (publish) last November in Nature Machine Intelligence. “A robot was     10     (likely) to obtain cooperation than another human, even though its strategy was clearly more beneficial to both players.”

It seems that there is a long way to go before trust in robots is established.

2 . Yue-Sai Kan was born in China. In 1972, she moved to New York. When Kan was a child, she was told by her father that she should always aim to (力争) be the first because no one remembered the second. What her father said has been a driving inspiration over the years for her to become a bestselling author and a successful businesswoman.

Her new book Be a Pioneer, which is the tenth she has written and her first Chinese-language autobiography (自传), was produced after three years, inspired by her father’s words.

When writing an autobiography, the biggest challenge is not how to present one’s life, but to remember it. To help with reconstructing her story, Kan asked many friends and colleagues she made over the years to write down their memories of her from earlier times. So besides featuring Kan’s own words, the new book is also filled with those of her friends’s, which gives Kan a new understanding of herself — a woman who works hard, studies hard. and the most important thing is that she is a woman filled with a sense of responsibility.

“My helper Stephanie mentioned that I was worried because we were running out of money for the company. My housekeeper reminded me that before the start of one of my events she found that I had fainted (晕倒) in the bathroom. I was so tired that I was getting sick. They know more about me than myself,” Kan says.

“Writing a book is a good business to be in, not so much to make money but to grow the brain. I believe what I do will benefit the world. All the things I have done in Be a Pioneer — my successes and my failures — can be a good example to young people in particular. That’s the main reason why I wrote the book,” adds Kan.

3 . When I was a child, I always wanted to be a superhero. I wanted to save the world and make everyone happy. But I knew that I’d need superpowers to make my dreams come true. So I used to embark on these imaginary journeys to find intergalactic (星系之间的) objects from planet Krypton, but didn’t yield much result. When I grew up and realized that science fiction was not a good source for superpowers, I decided instead to embark on a journey of real science, to find a more useful truth.

I started my journey in California, with a UC Berkeley 30-year longitudinal study that examined the photos of students in an old yearbook, and tried to measure their success and well-being throughout their life.By measuring the students’ smiles, researchers were able to predict how fulfilling and long-lasting a subject’s marriage would be, how well they would score on standardized tests of well-being, and how inspiring they would be to others.

Another aha moment came from a 2010 Wayne State University span research project that looked into pre-1950s baseball cards of Major League players. The researchers found that the span of a player’s smile could actually assist to predict the span of his life. Players who didn’t smile in their pictures lived an average of only 72.9 years, while players with beaming smiles lived an average of almost 80 years.

British researchers found that one smile can generate the same level of brain stimulation as up to 2,000 bars of chocolate. Wait — The same study found that smiling is as stimulating as receiving up to £16,000 in cash. That’s like $25,000 a smile. It’s not bad. And think about it this way: 25,000 times 400 — children smile as many as 400 times per day — quite a few kids out there feel like Mark Zuckerberg every day.

So whenever you want to tap into a superpower that will help you and everyone around you live a longer, healthier, happier life, smile.

C．Smiling is equal to eating 2,000 bars of chocolate.

D．Smiling can gain stimulation alike receiving cash.

A．Positive.

B．Doubtful.

C．Neutral.

D．Indifferent.

4. What is the text mainly about?

A．The journey to find the truth.

B．The hidden power of smiling.

C．The secret to a long and healthy life.

D．The significance of superhero studies.

4 . Which of your children is your favorite? Your response is probably “none of them.” What kind of parent would choose one child as his or her favorite? The truth might be surprising to you.

Years of research supports what many have suspected-most parents have a favorite child. Studies have explored reasons from birth order to gender (性别) and shared interests. Yet even with years of research that supports this idea, most parents tend to deny the fact that they have a favorite child. Even if there is no obvious parental favorite among siblings (兄弟姐妹), studies have shown that children often feel preferential treatment of their sibling by their parents. Favoritism often results in family conflicts and feelings of sadness among family members whether parents’ favoritism is real or only felt. Thus both the kids and their parents tend to be plagued by the favoritism.

The question isn’t whether or not you have a favorite child, since it’s pretty clear that many parents do. Typically, favoritism has little to do with loving one child more. It is more about how your personality resonates (产生共鸣) with one child’s personality more than the others’. Essentially, it’s a question of “like”. Still, why is it so hard for us to admit that one of our children might be our favorite? Some parents might worry about harming their children emotionally or psychologically. Some parents confuse liking one child’s personality with the love they show to each child. However, when recognizing that you might hold preferential feelings towards one child you are taking an important step towards creating a better relationship with all of your children.

Instead of denying the fact, you can reflect on how you relate to each of your children. Examining your feelings towards each of your children can provide a greater insight into your own personality and how you function in relationships -- and in fact, how you consider your children might reflect more about your thoughts and feelings of yourself than them. Increased awareness about your inner world can help you build and keep healthier relationships with your children.

7 . A team of researchers from the Universities of Washington and Toronto have developed an app, FeverPhone, suitable for diagnosing (诊断) a patient’s fever.

“As an undergraduate, I was doing research in a lab where we showed that you could use the temperature sensor in a smartphone to measure air temperature,” says lead author Joseph Breda. “When I came to the UW, my adviser and I wondered how we could apply a similar technique for health. We decided to measure fever in an accessible way. The primary concern with temperature isn’t that it’s a difficult signal to measure; it’s just that people don’t have thermometers (体温计).”

“In a wave of flu, for instance, people running to the emergency room can take a week sometimes. So if people were to share fever results with public health agencies through the app, this earlier sign could help us take action sooner,” adds Mastafa Springston, co-author of the study.

The trick is to use the temperature sensor already present in a smartphone. A patient holds the smartphone’s display against their forehead for 90 seconds, and the rise in temperature is compared against the surrounding temperature to determine their core body temperature — using a machine learning model trained on a number of test cases to calibrate the results.

It may sound like a crazy approach, but in testing, the FeverPhone app was able to estimate the core body temperature of 37 patients in a real emergency department with an average error of 0.23℃ — around half the 0.5℃ error range required for clinical use.

“We started with smartphones since they’re easy to get data from,” Breda says. “I am already working on seeing if we can get a similar signal with wearables like smartwatches. What’s nice, because watches are much smaller, is their temperature will change more quickly. So you could imagine having a user put a Fitbit to their forehead and measure in 10 seconds whether they have a fever or not.”

1. What inspired Breda to develop FeverPhone?

A．His adviser’s suggestion.	B．His previous research success.
C．His past experience in the UW.	D．His concerns about air temperature.

2. What does the underlined word “calibrate” in paragraph 4 probably mean?

A．Access.

D．Adjust.

3. What did the testing show about FeverPhone?

A．It was effective in measuring body temperature.	B．It was hardly suitable in a real emergency.
C．It was more useful than a real thermometer.	D．It was no more than a crazy solution.

4. Which is the most suitable title for the text?

10 . It is challenging to teach children about seasonal foods in a modern-day grocery store (杂货店). Having lots of choices of fresh produce from all around the world means that a sense of the seasons is lost. That’s why I like being part of a Community Supported Agriculture (CSA) program. Every week I receive a share of vegetables that comes from a nearby farm. I do not know ahead of time what I’m getting, nor do I have any say on what comes home; I take whatever was harvested earlier that same day, based on the week’s weather conditions, and use them to the best of my ability.

My kids have had a good knowledge of the supply of certain vegetables throughout the harvesting season. They know what it’s like to eat a lot of asparagus (芦笋) until they’re sick of it, only to move on to dark greens and leafy salads, then eggplants, and tomatoes, and finally the root vegetables that mark the arrival of cold weather.

The funny thing is, when you’ve eaten a ton of something for a few weeks, you’re ready to move on to the next crop (作物) and leave the other behind, but when its time comes the following year, the expectation will return. In this way, a CSA share creates excitement at vegetables that can’t be felt when everything can be bought all the time, as it is in a grocery store.

A farmers’ market can offer similar lessons in seasonality to a CSA, but it differs in that you have more choices about what you buy. A CSA share, however, only offers few kinds of vegetables and sometimes fruits, forcing you to work out ways of using them up. I enjoy this challenge because it tests my cooking skills and introduces my family to new and unusual vegetables. What’s more, it is glad to know I’m supporting local farmers by eating what they want to grow, not just what I’m used to eating.

1. What is special about the vegetables offered by the CSA program?

A．They are free.

B．They are cheap.

C．They can’t be found in local grocery stores.

D．They make the author full of expectations.

2. What does the author think of the CSA share?

A．It provides enough supply of vegetables.

B．It makes people choose vegetables freely.

C．It keeps people’s excitement for vegetables.

D．It makes people become sick of eating vegetables.

3. What does the author say about the program in the last paragraph?

A．It encourages him to support local farmers.

B．It helps him learn about the community.

C．It gives people more choices of foods.

D．It causes local farmers a lot of stress.

4. What is the best title for the text?

A．Local food is becoming more popular

B．The CSA program is making a difference

C．People are encouraged to experience farm life

D．Naturally grown food improves people’s health
