1 . Aspirin was discovered in 1897, and an explanation of how it works followed in 1995. That, in turn, has encouraged some research leads on making better pain relievers through something other than trial and error. This kind of discovery—answers first, explanations later—is called “intellectual debt”. We gain understanding of what works without knowing why it works. We can put that understanding to use immediately, and then tell ourselves we’ll figure out the details later. Sometimes we pay off the debt quickly; sometimes, as with aspirin, it takes a century; and sometimes we never pay it off at all.

In the Age of Intelligence, while machine learning presents lots of problems and gets things wrong, at least we know enough to be wary of the predictions produced by the system and to argue that they shouldn’t be blindly followed: but if a system performs perfectly (and we don't know why), then we come to rely on it and forget about it and suffer consequences when it goes wrong.

It’s the difference between knowing your car has faulty brakes and not knowing: both are bad, but if you know there is a problem with your brakes, you can increase your following distance, drive slowly and get to a mechanic as soon as possible. If you don't know, you're likely to find out the hard way, at 80mph on the highway when the car in front of you came to a sudden stop and your brakes give out.

We don’t have much by way of solutions. Most important, we shouldn’t trick ourselves into thinking that machine learning alone is all that matters. Indeed, without life value, machine learning may not be meaningful answers at all.

2 . A small but shining silver lining: The corona-virus has quickened the shift to pedal power in Europe. The German Cycling Association (ADFC) reports that Germans across the country are spending twice as much time biking as they were before the COVID-19. There is growing demand for bikes and shared-bike subscriptions, and now even shortages throughout bicycle supply chain. For bike shops it's an unexpected boom. So much so that it requires cities to improve their biking facilities.

In unimagined numbers, bikes are starting to take the place of cars in our cities. It has increased 930 miles of new bike lanes (车道) in Europe, “muscling aside cars on Europe’s city streets,” according to European Cyclists Federation. Belgium, Denmark, and the Netherlands are pioneering fast lanes for riders. “Pop-up lanes” are being used for bikes in Berlin and Paris; Rome has painted new bike lanes, in each case taking away lanes from cars.

Women riders are reportedly another big factor in the biking transformation. E-bikes are, too. E-bikes use an onboard battery to boost power when the rider is going up a hill, or just needs a rest. E-bikes have removed “the sweat factor”. Who wants to show up to work or a party sweaty?

The European Cyclists’ Federation states that bikes are also strongly supported by European governments to cut carbon and increase the quality of their cities. European countries provide direct financial stimulation for cyclists.

At the end of April, France announced a 20 million Euro plan to promote cycling after the end of the lockdown. The plan includes 50 Euro vouchers (代金券) for the repair of a bike. Italy worked on a regulation for Covid recovery, by means of which 120 million Euro was set aside to cover 70% and up to 500 Euro of the price of conventional, muscle-powered and electric bikes.

4 . Chinese researchers have analyzed big data to find that college students with better academic performance are more likely to eat breakfast especially on cold days, according to their findings published in a British journal.

In the Journal of the Royal Society Interface, they concluded there is a significant positive link between college students' academic performance and the regularity of campus daily life, in which having meals and taking a shower on time are two measuring factors.

In contrast to Western countries, teachers and administrators in most Asian countries often ask students to be self-disciplined both in and out of class. "Do routines in life help a student get better academic performance? We hope to answer this question,"said Zhou Tao, one of the researchers.

Researchers from the University of Electronic Science and Technology of China (UESTC) in Chengdu, Sichuan Province collected about 30 million digital behavioral records of 18,960 UESTC undergraduate students in three years. The behavioral records indicate a strong positive correlation (正相关) between academic performance and the regularity of campus daily life as their campus smart cards, which almost every student in Chinese universities owns, cover when they enter the library, take a shower, wash clothes, pay for meals in the cafeteria and other activities of daily routines. They are real-name registered and can be used for student identification as well as a payment medium on campus.

"The students with better performance are more likely to overcome difficulties and stick to their routines even on chilly mornings. The less the students are affected by weather conditions in keeping life routines, the more self-disciplined they are and the better grades they can get," said Gao Jian, another researcher of the study. "We are not aiming to ask all the students to live according to the same timetable, but to help school administrators detect undesirable，abnormal behavior and give them proper intervention (干涉) in time. For example, students who are addicted to online games often have an irregular lifestyle and those who always live alone are more likely to be depressed,"Zhou added.

1. Who his more likely to have good academic performance according to the text?

A．Tom, who often goes to the library.

B．Cathy, who skips breakfast on cold days.

C．Ken, who never takes a shower unless necessary.

D．Jane, who does things regularly in daily routine.

2. How did the researchers collect the behavioral records?

A．By credit cards.	B．With questionnaires.
C．By campus cards.	D．With brochures.

3. Which of the following will Gao Jian agree with according to the text?

A．Teachers in most Asian countries often ask students to be self-disciplined in class only.

B．Academic performance and the regularity of campus daily life are not necessarily associated.

C．The research is done to call on all students to live according to the same timetable.

D．The less affected by bad weather the students are, the better grades they can get.

4. What is the best title for the passage?

A．Self-discipline contributes to good health

B．Keeping fit makes you successful.

C．Irregular lifestyles may lead to depression.

D．Regular campus life helps you get ahead

5 . A handful of old mobile phones lay in a grey bucket. These outdated devices, which are about to be chopped into thousands of pieces, will be given a second life as recycled e-waste. But many phones won't.

According to the latest estimates, the world gets rid of approximately 50 million tonnes of waste annually. E-waste is full of dangerous materials that can cause damage to human health and the environment if not managed properly. But only 20 percent of global e-waste is recycled.The rest ends up in landfill, or burned—or is not recycled at all.

And yet,Switzerland is a good example of how to deal with the growing environmental issue. The country collects and recycles roughly 7S percent of this discarded material. This is thanks to a strong voluntary take-back system, where consumers can take e-waste to a reclining collection point or any electronic shop retailer（零售商）. A recycling station can be found within at most 300 meters from any residential area. Everyone gets involved. Switzerland's e-waste system is unique and can't be easily copied-due to a strong recycling culture within the country.

However, Switzerland faces the same global challenges as every nation.The built-in lithium batteries（锂电池）aren't easy to take out. The only way to remove these potentially dangerous components is with a bar and hammer. This poses a significant risk to those handling the goods. As such, producers need to be more transparent(信息透明的) and show more clearly where the harmful substances are, and how they can be removed.

Once the battery is removed, e-waste is sorted into different component parts—-metals, plastics and other materials. Roughly 70 percent of the device can be recycled. The material that cannot be recycled is used for other purposes like construction material or is burned to generate energy. Mobile phones—from a material perspective (角度), from a value perspective，and also from an environmental impact perspective -are very important.

For the past 15 years, Switzerland has been actively encouraging and supporting electrical waste disposal practices. They are happy to share their knowledge, experience, lessons learned, and they are happy if other people pick up on it.

1. What can we know about the global e-waste?

A．Only 20% of the e-waste is useful.

8 . Are You Emotional Intelligent?

They’re curious about people. It doesn’t matter if they’re introverted（内向的）or extroverted, emotionally intelligent people are curious about everyone around them.     1     —much of emotional intelligence comes down to social awareness, for example, the ability to read other people, know what they’re about, and understand what they’re going through.

They are difficult to offend. If they have a firm grasp of whom they are, it’s difficult for someone to say or do something that easily gets them annoyed.    2    , High EQ individuals keep their feelings in control. When they need to meet an annoying person, they approach the situation reasonably. They identify their own emotions and don’t allow anger or frustration to fuel chaos.

    3    . Emotionally intelligent people master their emotions because they understand them, and they use an extensive vocabulary of feelings to do so. While many people might describe themselves as simply feeling “bad,” emotionally intelligent people can clearly explain whether they feel “irritable,” “frustrated,” or “anxious.” The more specific your word choice, the better insight you have into exactly how you are feeling, what caused it, and what you should do about it.

They limit their caffeine intake. Drinking excessive amounts of caffeine leads to the release of adrenaline（肾上腺素）, which is the source of the fight-or-flight response. The fight-or-flight mechanism avoids reasonable thinking in favor of a faster response to survival.    4    , but not so great when they are responding to a curt（唐突无礼的）e-mail.

When making plans with friends or family, they will say their schedule is “flexible”, rather than “empty” or “free”.    5    , while not placing any hard limits.

A．And they are good judges of character

B．This is excellent when a bear is chasing you

C．They have a powerful emotional vocabulary

D．This can control the length or frequency of any activities

E．They are also quite important to the people around them

F．Self-confidence and open-mindedness create a pretty thick skin

G．This makes emotionally intelligent people as perfect as possible

9 . Ask any cat person to describe their cat friend, and they’ll likely affectionately say “jerkface”（小讨厌）. Cat people also know, however, that each little jerkface is its very own peculiar self.

According to a new research, each cat’s personality and behavior can be defined using a combination of just seven traits. The research was undertaken by way of a 138-question survey, posted on animal welfare website Petsofi, and filled out by the cats’ owners. This is because cats can behave very differently in a laboratory environment than the way they behave at home, so observing them in an experiment could produce inaccurate results.

The questionnaire asked people to enter, among other things, their cat’s sex, age, breed, coat color, and main activity. The humans were also asked to fill out the questionnaire a second time after a break had passed. This allowed the researchers to measure the accuracy of the reports by comparing the two surveys. The final sample consisted of 4,316 cats. From these, the researchers were able to narrow cat traits down to five personality traits and two behavioral traits:

Activity/playfulness

Fearfulness

Aggression（侵犯）towards humans

Sociability towards humans

Sociability towards cats

Litterbox issues（such as refusing to use the litterbox, or using it poorly）

Excessive grooming（臭美型）

Perhaps unsurprisingly, the results also revealed that different breeds skew towards（偏向）different personality traits. “The most fearful breed was the Russian Blue, while the Abyssinian was the least fearful,” says veterinary scientist Hannes Lohi of the University of Helsinki. “The Bengal was the most active breed, while the Persian and Exotic were the most passive. The breeds exhibiting the most excessive grooming were the Siamese and Balinese, while the Turkish Van breed scored considerably higher in aggression towards humans and lower in sociability towards cats.”

1. In which way could the research be undertaken?

A．By voting on an animal welfare website.

B．By filling out a form of different cat traits.

C．By finishing a survey about cats twice.

D．By answering the questionnaire in public.

2. What can we infer from Paragraph 2?

A．The whole research is an experiment on an animal welfare website Petsofi.

B．Cats may present quite different action without their owners aside.

C．The survey in the research contained 138 questions about how to provide welfare.

D．A laboratory environment could generate better results than in real life.

3. The following traits are mentioned in examples EXCEPTA

A．Sociability towards humans and Sociability towards cats.

B．Aggression towards humans and Excessive grooming.

C．Activity/Playfulness and Fearfulness.

D．Fearfulness and Aggression towards humans.

4. What do we know about cats according to the passage?

A．Humans dislike cats so that they affectionately call them “jerkface”.

B．There are seven personality traits of them in all among 4,316 samples.

C．The questionnaire asked people to describe the interaction between cats and them.

D．The traits of cats are defined through behavior and individuality.

10 . Across the developing world, homeowners, farmers, and businesses are turning to cheap, secondhand solar to fill power gaps left by governments and utilities. To meet that demand, businesses ranging from individual sellers on Facebook to specialized brokerages are getting into the trade.

Earlier this month, Marubeni Corp., one of Japan’s largest trading houses, announced that it’s establishing a blockchain-based market for used solar panels（太阳能板）. Collectively, these businesses will likely play a crucial role in bringing renewable energy to the world’s emerging markets（新兴市场）—and keeping high-tech waste out of the trash.

In 2016, the International Renewable Energy Agency estimated that as much as 78 million tons of solar-panel waste will be generated by 2050. That’s almost certainly an undercount. Over the past decade, falling prices and improved efficiency in newer models have offered a strong incentive to replace solar panels earlier than their intended lifespan. By one estimate, those upgrades could lead to 50 times more waste than the agency has predicted within five years.

In developed countries, recycling-not reuse and resale-tends to be the natural response to managing such waste. But there are two problems with recycling unwanted solar panels. First, doing so is far costlier than simply burying them. Second, waste solar panels often aren’t waste, they’re just degraded by time in the sun or less efficient than newer models. They may not be good enough for San Francisco homeowners and advanced utilities, but they work perfectly well for anyone in a sunny climate in need of stable, off-grid（离输电网）power who doesn’t want to pay full price.

That’s potentially a huge market. Between 2010 and 2019, the number of people living without electricity declined from 1.2 billion to 759 million in developing countries. Some of that gap was closed by new power lines and other transmission facilities. But most of it was achieved by installing used solar panels to power a village, farm or even a single home. As of last year, 420 million people got their electricity from off-grid solar systems. By 2030, according to the World Bank, that number could nearly double.
