Your next ca might drive itself. After years of trials on city streets, driverless vehicles are now nearing the live phase. Last moth, a driverless bus began carrying passengers through Lyon, France, Most in the automobile industry think self-driving vehicles will be on the road by 2020 or before.

Driverless cars will at first be huddled with human-driven cars. But the first places where they will become dominant(统治的)are dense urban areas — precisely the spots most damaged by the automobile age. Many advanced cities are already reducing the role of human-driven cargo. Driverless cars will quicken that process and will bring us enormous benefits.

Driverless cars will reduce accidents by around 90 percent. That’s big—the annual death toll on the world’s roads is about 1.2 million a year. Pollution and carbon emissions will drop, because urban driverless cars will be electric. The old, otherwise they would stay at home most of the time and the disabled and teenagers will suddenly gain mobility.

On the other hand, driverless cars will bring catastrophe. The best thing about the automobile age was that it employed tens of millions of people to make, market, insure and drive vehicles. Over the next 20 years, the mostly low-skilled men who now drive trucks, taxis and buses will see their jobs reduced. Carmakers are especially scared. The few cars of the future might be made by tech companies such as Apple, Baidu and Google. Imaging the impact on Germany, where the automotive sector is the largest industry.

Dramatic change is coming, and driverless cars could arrive by 2020. But governments have barely begun thinking about it. Only 6 percent of the biggest US cities have factored them into their long-term planning.

A decade ago anyone hardly saw the Smartphone coming. It has bought an epidemic of mass addiction. Let’s hope we do a better job of handling the driverless car.

Aerial performer Jennifer Bricker was born without legs, but she never let it stop her.

Wrapped in a loop of red silk hung from the ceiling Jennifer Bricker climbs and twists to the music. Her head hangs down and her strong arms let go as she balances on her back, high above the ground a move that’s all the more daring because she has no legs.

Jennifer was a few months old when she was adopted by Sharon and Gerald Bricker. She had big brown eyes, a bright smile, and huge amounts of energy. When a doctor advised her adoptive parents to carry her around in a kind of bucket, they refused.

Jennifer soon learned to walk — and run — on her hands and bottom, and grew up fearlessly climbing trees and bouncing on the trampoline(蹦床) with her three older brothers. “My parents didn’t treat me differently so I didn’t grasp the concept that I was different. I knew I didn’t have legs but that wasn’t stopping me from doing the things I wanted to do.”

At the age of three she was fitted with artificial legs, but she never really took to them — she moved more freely without.

In 1996 the Olympic Games took place in Atlanta. Jennifer loved to watch the women’s gymnastics team, and especially adored the 14-year-old Dominique Moceanu who competed for the US. When Moceanu and the women’s team won gold, Jennifer decided she was going to be a gymnast, too. She took up power tumbling, which involves performing floor exercises down a runway. But Jennifer did not want any allowances to be made for her disability.

At the age of 10 she took part in the Junior Olympics and by age 11 she was tumbling champion for the state of Illinois.

Jennifer now travels the world as an inspirational speaker and acts as an aerial performer.

2.What do we know about Jennifer Bricker?

A. She felt embarrassed without legs.

B. She was carried in a bucket as a baby.

C. She was brought up as a normal child.

On Monday, the Centers for Disease Control and Prevention predicted that 42% of Americans could be overweight by 2030. Our expanding waistlines lead to not only a medical problem, but according to a recent article In The New York Times, it could also endanger personal safety in some situations—in an airplane crash, for example.

The New York Times’ Christen Negroni reports that engineers and scientists are questioning whether airplane seats are adequately constructed to protect overweight travelers. Government standards for airplane seat strength(强度)— first set moe than 60 years ago — require that the seats be made for a passenger weighing 170 pounds (77kg). Today, the average American man weighs nearly 194 pounds (88kg) and the average woman 165 pounds (75kg). Negroni reports:

“If a heavier person completely fills seat, the seat is not likely to behave as intended during a crash,” said Robert Salazar, the leading scientist at the Center for Applied Biomechanics at the University of Virginia. “The energy absorption that is built into the aircraft seat is likely to be overpowered and the passengers will not be protected properly.”

“Nor would the injury be limited to that passenger only,” Dr. Salzar said. “If a seat or a seat belt fails,” he said, “those people who are seated nearby could be endangered from ‘the uncontrolled movements of the passenger’.”

Most complaints about airplane seats focus on their lack of comfort and high ticket price, and whether overweight passengers should be made to buy two seats. But The New York Times’ article brings up another reason to feel anxious about flying. Investigators of the issue got in touch with the airplane seat and seat belt makers, but they refused to comment on the problem. Experts agreed that crash testing should be done with overweight dummies (人体模型). Both airplane seats and seat belts should be tested, they said.

Fortunately, however, according to Nora Marshall, a senior adviser at the National Transportation Safety Board, the board’s investigators have never seen an accident involving a commercial plane in which the weight of a passenger was a problem.

1.What is the article in The New York Times mainly concerned with?

A. The size of airplane seats and seat belts.

B. Safety of overweight airplane passengers.

C. Airplane crashes involving commercial planes.

D. A medical problem caused by being overweight.

2.Robert Salzar would probably agree that .

A. overweight passengers should buy two seats

B. the government should help produce safer planes

C. standards for airplane seat strength should be raised

D. passengers should know how to protect themselves

3.We can learn from the text that .

A. airplane seat makers have taken action now

B. there are few complaints about airplane seats

C. those seate near the overweight may suffer too

D. only a small number of airplane accidents involve the overweight

4.What is the best title for the text?

A. Why Do Passengers Feel Anxious about Flying?

B. Will 42% of Americans Be OVERWEIGHT BY 2030?

C. When Will the Overweight Enjoy Their Flight?

D. Are Airplane Seats Safe Enough for the Overweight?

I am Henry Jekyll. I was born in the 1800s. I inherited(继承) a large fortune, a healthy body and an excellent mind. I was naturally hard-working and soon I was very successful in my job. So the outside world saw a serious, hard-working, successful doctor. Behind this quiet character, however, was a wild, fun-loving, irresponsible young man. Both of them were me. They lived together in the same body.

“Was it possible,” I wondered, “to find a drug that could give each side of my character its own separate face and body?”

After much thought and careful study I believed I had found the answer. I had read many scientific books and spent many hours in my laboratory, searching for the right mixture of chemicals to make my drug. At last I got everything ready.

Late one night, I mixed everything together and prepared my drug. I watched the smoke rising from the liquid as its color changed from red to purple and at last to green. Then, bravely, I drank every bitter drop.

I felt a violent sickness in my stomach and a terrible pain in all my bones. The room seemed to turn round and round and I trembled with fear. Then the fear and pain disappeared and a strange, sweet feeling took its place. Wild thoughts danced through my mind—the wild passions of an evil and cruel stranger. But inside myself I felt younger, lighter, more carefree than ever before. “If this is pure evil,” I thought, “I like it.”

I stood there, enjoying these strange new thoughts and passions and suddenly realized that I was shorter. So I decided to go to my bedroom in my new body and take a look at myself in the mirror there. As I came into my room, I saw Edward Hyde for the first time.

At that time, the good side of my character was stronger than the evil side. Henry Jekyll had his faults, but he was mostly a good, kind man. I believe that is the reason why Edward Hyde was so much smaller than Henry Jekyll. But that was not the only difference between the two men. Henry Jekyll had a kind, open, honest face. But pure evil stared out of Edward Hyde’s eyes. I felt no dislike, however. Indeed, I welcomed him. Edward Hyde was me, young and strong and full of life.
