1 . Preparing Cities for Robot Cars

The possibility of self-driving robot cars has often seemed like a futurist’s dream, years away from materializing in the real world. Well, the future is apparently now. The California Department of Motor Vehicles began giving permits in April for companies to test truly self-driving cars on public roads. The state also cleared the way for companies to sell or rent out self-driving cars, and for companies to operate driverless taxi services. California, it should be noted, isn’t leading the way here. Companies have been testing their vehicles in cities across the country. It’s hard to predict when driverless cars will be everywhere on our roads. But however long it takes, the technology has the potential to change our transportation systems and our cities, for better or for worse, depending on how the transformation is regulated.

While much of the debate so far has been focused on the safety of driverless cars (and rightfully so), policymakers also should be talking about how self-driving vehicles can help reduce traffic jams, cut emissions (排放) and offer more convenient, affordable mobility options. The arrival of driverless vehicles is a chance to make sure that those vehicles are environmentally friendly and more shared.

Do we want to copy — or even worsen — the traffic of today with driverless cars? Imagine a future where most adults own individual self-driving vehicles. They tolerate long, slow journeys to and from work on packed highways because they can work, entertain themselves or sleep on the ride, which encourages urban spread. They take their driverless car to an appointment and set the empty vehicle to circle the building to avoid paying for parking. Instead of walking a few blocks to pick up a child or the dry cleaning, they send the self-driving minibus. The convenience even leads fewer people to take public transport — an unwelcome side effect researchers have already found in ride-hailing (叫车) services.

A study from the University of California at Davis suggested that replacing petrol-powered private cars worldwide with electric, self-driving and shared systems could reduce carbon emissions from transportation 80% and cut the cost of transportation infrastructure (基础设施) and operations 40% by 2050. Fewer emissions and cheaper travel sound pretty appealing. The first commercially available driverless cars will almost certainly be fielded by ride-hailing services, considering the cost of self-driving technology as well as liability and maintenance issues (责任与维护问题). But driverless car ownership could increase as the prices drop and more people become comfortable with the technology.

Policymakers should start thinking now about how to make sure the appearance of driverless vehicles doesn’t extend the worst aspects of the car-controlled transportation system we have today. The coming technological advancement presents a chance for cities and states to develop transportation systems designed to move more people, and more affordably. The car of the future is coming. We just have to plan for it.

What is the author’s attitude to the future of self-driving cars?

A.Doubtful.
B.Positive.
C.Disapproving.
D.Sympathetic.

2 . Live with roommates? Have friends and family around you? Chances are that if you’re looking to live a more sustainable lifestyle, not everyone around you will be ready to jump on that bandwagon.

I experienced this when I started switching to a zero waste lifestyle five years ago, as I was living with my parents, and I continue to experience this with my husband, as he is not completely zero waste like me. I’ve learned a few things along the way though, which I hope you’ll find encouraging if you’re doing your best to figure out how you can make the change in a not-always-supportive household.

Zero waste was a radical lifestyle movement a few years back. I remember showing my parents a video of Bea Johnson, sharing how cool I thought it would be to buy groceries with jars, and have so little trash! A few days later, I came back with my first jars of zero waste groceries, and my dad commented on how silly it was for me to carry jars everywhere. It came off as a bit discouraging.

Yet as the months of reducing waste continued, I did what I could that was within my own reach. I had my own bedroom, so I worked on removing things I didn’t need. Since I had my own toiletries (洗漱用品), I was able to start personalising my routine to be more sustainable. I also offered to cook every so often, so I portioned out a bit of the cupboard for my own zero waste groceries. Perhaps your household won’t entirely make the switch, but you may have some control over your own personal spaces to make the changes you desire.

As you make your lifestyle changes, you may find yourself wanting to speak up for yourself if others comment on what you’re doing, which can turn itself into a whole household debate. If you have individuals who are not on board, your words probably won’t do much and can often leave you feeling more discouraged.

So here is my advice: Lead by action.

What was the attitude of the author’s father toward buying groceries with jars?

A.He disapproved of it.
B.He was favorable to it.
C.He was tolerant of it.
D.He didn’t care about it.

3 . Grizzly bears, which may grow to about 2.5 m long and weigh over 400 kg, occupy a conflicted corner of the American psyche — we revere (敬畏) them even as they give us frightening dreams. Ask the tourists from around the world that flood into Yellowstone National Park what they most hope to see, and their answer is often the same: a grizzly bear.

“Grizzly bears are re-occupying large areas of their former range,” says bear biologist Chris Servheen. As grizzly bears expand their range into places where they haven’t been seen in a century or more, they’re increasingly being sighted by humans.

The western half of the US was full of grizzlies when Europeans came, with a rough number of 50,000 or more living alongside Native Americans. By the early 1970s, after centuries of cruel and continuous hunting by settlers, 600 to 800 grizzlies remained on a mere 2 percent of their former range in the Northern Rockies. In 1975, grizzlies were listed under the Endangered Species Act.

Today, there are about 2,000 or more grizzly bears in the US. Their recovery has been so successful that the US Fish and Wildlife Service has twice attempted to delist grizzlies, which would loosen legal protections and allow them to be hunted. Both efforts were overturned due to lawsuits from conservation groups. For now, grizzlies remain listed.

Obviously, if precautions (预防) aren’t taken, grizzlies can become troublesome, sometimes killing farm animals or walking through yards in search of food. If people remove food and attractants from their yards and campsites, grizzlies will typically pass by without trouble. Putting electric fencing around chicken houses and other farm animal quarters is also highly effective at getting grizzlies away. “Our hope is to have a clean, attractant-free place where bears can pass through without learning bad habits,” says James Jonkel, longtime biologist who manages bears in and around Missoula.

How do Americans look at grizzlies?

A.They cause mixed feelings in people.
B.They should be kept in national parks.
C.They are of high scientific value.
D.They are a symbol of American culture.

4 . “What would the world be if there were no hunger?” It’s a question that Professor Crystal would ask her students. They found it hard to answer, she wrote later, because imagining something that isn’t part of real life—and learning how to make it real—is a rare skill. It is taught to artists and engineers, but much less often to scientists. Crystal set out to change that, and helped to create a global movement. The result—an approach known as systems thinking—is now seen as essential in meeting global challenges.

Systems thinking is crucial to achieving targets such as zero hunger and better nutrition because it requires considering the way in which food is produced, processed, delivered and consumed, and looking at how those things intersect (交叉 ) with human health, the environment, economics and society. According to systems thinking, changing the food system—or any other network—requires three things to happen. First, researchers need to identify all the players in that system; second, they must work out how they relate to each other; and third, they need to understand and quantify the impact of those relationships on each other and on those outside the system.

Take nutrition. In the latest UN report on global food security, the number of undernourished (营养不良 )people in the world has been rising, despite great advances in nutrition science. Tracking of 150 biochemicals in food has been important in revealing the relationships between calories, sugar, fat and the occurrence of common diseases. But using machine learning and artificial intelligence, some scientists propose that human diets consist of at least 26,000 biochemicals—and that the vast majority are not known. This shows that we have some way to travel before achieving the first objective of systems thinking - which,in this example, is to identify more constituent parts of the nutrition system.

A systems approach to creating change is also built on the assumption that everyone in the system has equal power. But as some researchers find, the food system is not an equal one. A good way to redress (修正 ) such power imbalance is for more universities to do what Crystal did and teach students how to think using a systems approach.

More researchers, policymakers and representatives from the food industry must learn to look beyond their direct lines of responsibility and adopt a systems approach. Crystal knew that visions alone don’t produce results, but concluded that “we’ll never produce results that we can’t envision”.


As for systems thinking, which would the author agree with?
A.It may be used to justify power imbalance.
B.It can be applied to tackle challenges.
C.It helps to prove why hunger exists.
D.It goes beyond human imagination.

5 . 1. The US scientists who created the first living robots say the life forms, known as xenobots, can now reproduce—and in a way not seen in plants and animals. Xenobots are formed from the stem cells of the African clawed frog (Xenopus laevis), from which it takes its name.

“Frogs have a way of reproducing that they normally use, but when you liberate the stem cells from the embryo(胚胎) and you give them a chance to figure out how to be in a new environment, not only do they figure out a new way to move, but they also figure out apparently a new way to reproduce,” said Michael Levin, a professor of biology at Tufts University, who was co-lead author of the new research.

Stem cells are unspecialized cells that have the ability to develop into different cell types. To make the xenobots, the researchers removed living stem cells from frog embryos and left them to develop.

“Most people think of robots as being made of metal, but it’s not so much what a robot is made from but what it does, which is act on its own on behalf of people,” said Josh Bongard, a computer science professor and robotics expert at the University of Vermont and lead author of the study. “In that way, it’s a robot, but it’s also clearly an organism made from frog cells.”

The researchers found that the xenobots could replicate(自我复制). But it happened rarely and only in specific circumstances. The xenobots used “kinetic replication”—a process that is known to occur at the molecular(分子) level.

With the help of artificial intelligence, the researchers then tested billions of body shapes to make the xenobots more effective at this type of replication. The supercomputer came up with a C-shape that looked like Pac-Man, the 1980s video game. They found it was able to find tiny stem cells, gather hundreds of them inside its mouth, and a few days later the pack of cells became new xenobots.

“The AI didn’t program these machines in the way we usually think about writing code. It shaped and sculpted and came up with this Pac-Man shape,” Bongard said. “The shape is, in essence, the program. The shape influences how the xenobots behave to speed up this incredibly surprising process.”

The xenobots are very early technology-think of a 1940s computer—and don’t yet have any practical applications. However, this combination of molecular biology and artificial intelligence could potentially be used in many tasks in the body and the environment. This may include things like collecting microplastics in the oceans, inspecting root systems and regenerative medicine. “There are many things that are possible if we take advantage of this kind of plasticity and ability of cells to solve problems,” Bongard said.


What is the author’s attitude towards future applications of xenobots?
A.Disapproving.
B.Optimistic.
C.Unconcerned.
D.Objective.

6 . We’ve heard for years that breakfast is the most important meal of the day. But, it actually might be even more important than previously thought, according to a study published in the Journal of the Academy of Nutrition and Dietetics, which examined the effects of skipping meals and meal frequency as related to mortality (死亡率) and heart health.

The study, which was published in August of last year, sought to find out if eating behaviors like meal frequency, meal skipping, and time between meals were associated with all-cause and cardiovascular disease (CVD) mortality.

The study consisted of 24,011 adults 40 years or older who participated from 1999 to 2014. Researchers looked at various eating behaviors of participants who self-reported their eating habits every 24 hours. Causes of death were tracked via death records through December 31, 2015.

After examining participants throughout the years, researchers found that certain eating behaviors were in fact linked to higher rates of premature death. Eating only one meal per day was associated with an increased risk of all-cause and CVD mortality while skipping breakfast was linked to an increased risk of CVD mortality, and skipping lunch or dinner was linked to an increased risk of all-cause mortality. Lastly, the study found that having meals too closely together (less than four and half hours apart) was also linked to all-cause premature death.

So, what does this mean for the average person? “At the end of the day what matters is that an individual can meet their nutritional needs for optimal (最佳) health,” explains Keri Gans, author of The Small Change Diet, “and breakfast typically is a good vehicle for nutrients associated with a decrease in cardiovascular risk, such as fiber and vitamins”. “If by eliminating meals they are missing out on important nutrients their body needs, then long term that can be harmful to their health,” leads to a “higher risk for certain cancers and heart disease,” she says.

While this study was large and comprehensive in many ways, there are also many limitations. It was mostly based on a 24-hour, self-reported dietary recall, “which may not always be the best method for dietary assessment,” explains Gans. “The participants may not accurately recall what they ate or honestly report it leading to the potential of misinformation.” Researchers noted that it was impossible to consider the role of sleep in the relationship between food and mortality, as well as a host of other unmeasured factors.

The bottom line is that while these findings about the relationships between meal skipping and mortality are important, there are a lot more factors that go into premature death.


What is the author’s attitude towards skipping breakfast?
A.Favorable.
B.Unconcerned.
C.Skeptical.
D.Disapproving.

7 . What is life? Like most great questions, this one is easy to ask but difficult to answer. The reason is simple: we know of just one type of life and it’s challenging to do science with a sample size of one. The field of artificial life-called ALife for short — is the systematic attempt to spell out life’s fundamental principles. Many of these practitioners, so-called ALifers, think that somehow making life is the surest way to really understand what life is.

So far no one has convincingly made artificial life. This track record makes ALife a ripe target for criticism, such as declarations of the field’s doubtful scientific value. Alan Smith, a complexity scientist, is tired of such complaints. Asking about “the point” of ALife might be, well, missing the point entirely, he says. “The existence of a living system is not about the use of anything.” Alan says. “Some people ask me, ‘So what’s the worth of artificial life?’ Do you ever think, ‘What is the worth of your grandmother?’”

As much as many ALifers hate emphasizing their research’s applications, the attempts to create artificial life could have practical payoffs. Artificial intelligence may be considered ALife’s cousin in that researchers in both fields are enamored by a concept called open-ended evolution (演化). This is the capacity for a system to create essentially endless complexity, to be a sort of “novelty generator”. The only system known to exhibit this is Earth’s biosphere. If the field of ALife manages to reproduce life’s endless “creativity” in some virtual model, those same principles could give rise to truly inventive machines.

Compared with the developments of Al, advances in ALife are harder to recognize. One reason is that ALife is a field in which the central concept — life itself — is undefined. The lack of agreement among ALifers doesn’t help either. The result is a diverse line of projects that each advance along their unique paths. For better or worse, ALife mirrors the very subject it studies. Its muddled (混乱的) progression is a striking parallel (平行线) to the evolutionary struggles that have shaped Earth biosphere.

Undefined and uncontrolled, ALife drives its followers to repurpose old ideas and generated novelty. It may be, of course, that these characteristics aren’t in any way surprising or singular. They may apply universally to all acts of evolution. Ultimately ALife may be nothing special. But even this dismissal suggests something:perhaps, just like life itself throughout the universe, the rise of ALife will prove unavoidable.


Regarding Alan Smith’s defence of ALife, the author is________.
A.supportiveB.puzzledC.unconcernedD.doubtful

9 . A new research has found that comedy doesn’t just make us feel good — it actually has the power to improve health. A recent study was conducted to test whether or not “laughter therapy (疗法)”could help people who have heart disease.

The study involved 26 adults, with an average age of 64. They all had coronary artery (冠状动脉) disease, which happens when the supply of blood to the heart is held up by plaque (斑块)   that grows in the coronary arteries, the big tubes that send blood to the heart. Over three months, 13 of the adults were asked to watch two-hour-long comedy shows every week. The other 13 were asked to watch two documentary films on serious topics like politics and the Amazon rainforest. Then, the participants were examined by doctors.

The first group that watched comedy showed a big improvement in the amount of oxygen which we breathe in to survive and that the heart could pump around the body. Their arteries also got better at expanding, which meant that more blood could flow through them. There was less plaque in the arteries afterward too, cutting the person’s risk of having a heart attack or stroke.

The study was led by Marco Saffi, a professor at a hospital, who said laughter helps the heart because it releases chemicals in the body called endorphins. They reduce inflammation, which can lead to heart disease, and help the heart relax.

Having a good laugh also reduces levels of stress hormones (荷尔蒙). Stress hormones are the body’s natural alarm system, which kicks in if a person is in a tense situation. They’re great for helping people cope with danger, but they can put a strain on the heart if they stay in a person’s system for too long.

Saffi thinks the results show “laughter therapy” could be used to treat patients at the risk of heart problems. He said, “It does not have to be TV programs — people with heart disease could be invited to comedy evenings or encouraged to enjoy fun evenings with friends and family.”

How does Saffi feel about “laughter therapy”?
A.It’s costly.B.It’s unique.C.It’s promising.D.It’s unworthy.

10 . One time my friends and I drove three hours to Devil’s Lake, Wisconsin, to climb the purple quartz (石英) rock around the lake. After we found a crazy-looking road that hung over a bunch of rocks, we decided to photograph the scene at sunset. The position enabled us to look over the lake with the sunset in the background. We managed to leave this spot to climb higher because of the spare time until sunset. However, we did not mark the route (路线) so we ended up almost missing the sunset entirely. Once we found the place, it was stressful getting lights and cameras set up in the limited time. Still, looking back on the photos, they are some of my best shots though they could have been so much better if I would have been prepared and managed my time wisely.

How does the author find his photos taken at Devil’s Lake?
A.Amusing.B.Satisfying.
C.Encouraging.D.Comforting.
