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.
1.According to the author, attention should be paid to how driverless cars can __________.
A. help deal with transportation-related problems
B. provide better services to customers
C. cause damage to our environment
D. make some people lose jobs
2.As for driverless cars, what is the author’s major concern?
A. Safety. B. Side effects.
C. Affordability. D. Management.
3.What does the underlined word "fielded" in Paragraph 4 probably mean?
A. Employed. B. Replaced.

The teachers are preparing their classrooms for the start of classes. As their principal, I was energized by their enthusiasm. Everywhere I went, I asked the same question, “How are you doing?” And everywhere I went, I received the same answer, “just fine.”
There was only one person whom I didn’t quite believe. It was her first year of teaching. Her classroom was inviting. She seemed well-prepared. On the outside everything seemed just fine, but there was something in her eyes that mad me ask that question again and again.
Then came Wednesday. “How are you doing?” I asked. “Mr. Boyce, I think I’m going to make it,” she said. The office was full of teachers and noise, but the voices became quiet as the young teacher continued.
“Monday night, after our open house (开放参观日),I just didn’t think I could do it. There were so many parents and children, and I felt under great pressure. When I told my family I didn’t think I could do it , they said I had to try.
“The next morning school started. I thought I was ready, but there were so many of them and their needs were so different. I just didn’t know how I could manage.
“I said to my parents if I had fewer kids I could handle it. So they asked me which children I would get rid of. But I couldn’t decide. I’d only had them for one day, but I couldn’t think of a single child I could do without. They’re mine. I can’t do without any of them. I don’t know how, but I’m just going to do the best I can and I really think I’m going to make it. “
There wasn’t a dry eye in the office when I replied, “I think you are, too.”

January means it’s time for coats and gloves and cold weather. While many of us are preparing ourselves for the cold weeks ahead, in some cities winter is the “hottest” season of all because it’s the time for winter festivities.
Every year 2 million people visit the Sapporo Snow Festival in Japan. This internationally well-known event began in 1950, when some local high-school students built six snow statues in Odori Park. Since then, the festival has grown to include lots of snow sculptures as well as a snow-sculpting contest that draws competitors from all over the world.
In December, Finland created its 13th annual Snow Village, which will remain open until April, if weather permits. Snow Village lies nearly 200 kilometers north of the Arctic Circle. The village is designed by builders skilled in working with snow and ice. Visitors can take a tour of the village, eat in a restaurant made of ice or go dancing in the disco igloo(拱形圆顶小屋). They can also spend the night in a hotel made of snow. There’s even an ice chapel(小礼拜堂) for couples who want to get married in Snow Village.
Since 1935, the Fur Rendezvous has been held every February in Anchorage, Alaska, America’s most northern state. Among the festival’s many attractions is the World Championship Sled Dog Race, which draws sled dog teams from many countries. Dogs also take center stage in the Dog Weight Pull, in which dogs compete to see which one can pull the heaviest weight. The festival features sports like skiing, basketball, boxing and softball as well as the Grand Prix Auto Race in downtown Anchorage. True to the festival’s name, there’s also a fur auction(拍卖), where buyers buy real Alaskan furs. The first Fur Rendezvous lasted only three days. Now it’s a 10-day event that attracts thousands of visitors.
1.What can we learn about the Sapporo Snow Festival from the second paragraph?
A. How it got started. B. How long it lasts.
C. Who is in charge of it. D. How much it costs to attend it.
2.What happens at Snow Village?
A. Skating matches. B. Design contests.
C. Indoor weddings. D. Cooking competitions.
3.Anyone who visits the Fur Rendezvous can .
A. buy what he wants B. play any sports he likes
C. attend a strength competition D. come across different sled dogs
4.what do the three winter festivities mentioned in the text have in common?

阅读下面短文,根据其内容写一篇60词左右的内容概要。
Most students experience a lot of stress while preparing for exams,as both their parents and teachers expect them to get high scores. Students who feel anxious are likely to experience problems like difficulty in concentrating while studying,confusion,feeling stressed while looking at difficult questions,feeling blank,sweating,sleepless,etc. Under such circumstances they end up scoring less than they could have. Therefore,it's extremely important for students to learn about how to overcome fear,so that they can take their examination confidently,finally earning good grades. Here are a few tips on ways to overcome exam fear.
There are many students who take studies lightly,leaving everything to be studied at the last minute. As a result,when exams are around the corner,they feel scared,as they don't know where to start,and what to study. So the easiest way of overcoming this problem is to start studying much before the exam. Another common mistake that many students make is that they don't make an effort to understand the subject. When they have memorized without understanding,the chances of forgetting are more. Therefore,it is vital to understand the concept before memorizing it. In this way, you will never forget any important point. Besides,that the exams are coming does not mean that you have to sit with your books for the entire day,and students should take regular breaks to relax and refresh their mind. However,they should avoid watching too much TV and addicting themselves to the Internet,in which way,they are more likely to waste time.
Apart from the tips above,here are some points that will help students cope with exam-related anxiety. For example,before the exam,avoid studying anything new or having conversations with your classmates about what they have studied and how much they have studied,both of which will make you more nervous. During the exam, if you get blank after seeing difficult questions,ignore them for the time being,and attempt those you find easier. Once you have completed them,go back to the difficult ones.
