China’s new bullet train is now the world’s fastest land vehicle (交通工具) China Rail-way Rolling Stock Corporation showed the production version of its magnetic levitation (磁悬浮) bullet train in Qingdao on Tuesday. State media says the train has a top speed of 373 mph. That speed doesn’t just make it the fastest train in the world, but makes it the fastest land vehicle. The bullet train is able to travel at such high speeds because of magnetic levitation. The technology uses electro-magnetic force to levitate the body of the vehicle less than two inches from the rails and drive it forward along the tracks. By riding on a cushion of air, friction (摩擦力) is completely reduced, allowing it to travel faster than traditional trains where wheels and rails are constantly in contact. Although China has made use of the technology for a couple decades now, it’s only ever been used at very limited areas.

China Railway says its bullet train will greatly help cut down travel time. At top speedy the vehicle will be able to complete the 754-mile trip between Beijing and Shanghai in just two and a half hours. That same trip takes just over three hours by plane, five and a half hours by current high-speed rail options or 12 hours by car. That could make the train an especially attractive travel option for business travelers in the country. It’s unclear when the new bullet train will go into operation. The vehicle that the company showed off on Tuesday is the finished article.

Of course, the train’s record might not stand for long. The Central Japan Railway Company is testing a maglev train. It will be able to top out at 375 mph, according to New Atlas. But that isn’t expected to be shown in public until 2027 at the earliest. That gives China Railway Rolling Stock Corporation plenty of time to refine and upgrade its bullet train and push its top speed even higher.

A.It is the fastest land vehicle.
B.It is close to the speed of sound.
C.It has gone into operation widely.

A.The poor management of it.
B.The lack of money used to improve the train.

文章大意:这是一篇说明文。短文介绍了洛杉矶街道设计的不合理之处以及改进措施。

【推荐2】On Feb. 21, four students were standing on the side of Pacific Coast Highway in Malibu when a driver going 110 miles per hour lost control of his car and it crashed into the parked vehicles.12 people were killed at the scene, including 2 drivers.

This kind of traffic death shouldn’t be called an accident. In Los Angeles, we seem to have accepted constant carnage (屠杀) in our streets in exchange for maximizing driver speed and convenience. The official responses to proven traffic dangers are mere gestures, if even that.

Los Angeles is a uniquely deadly city with a death rate that is four times the national average. Unsurprisingly, it’s also a city that has been designed with one thing in mind: a concept called level of service, which grades streets on how well they serve those in automobiles. To many Angelenos, that makes sense — to design our streets for car traffic, which is the way many get around the city. Unfortunately, we don’t recognize that there’s a trade-off. We can either have streets bettered for free-flowing traffic, or we can design streets for people to move around safely outside of cars.

City leaders consistently choose for the easy but deadly option. In one recent example, a resident asked the city’s Department of Transportation to block drivers from using Cochran Avenue at Venice Boulevard as a cut-through street, as they were speeding through a quiet residential neighbourhood. The department responded by suggesting a “speed awareness campaign” in which neighbours put up yard signs urging drivers to slow down.

People don’t drive based on signage, but they drive on the design of the street. The trunk roads of Los Angeles such as Venice Boulevard all need to be revised so that people are prioritized over cars. This would include narrowing travel lanes (道), building bike lanes, and banning right turns at red lights. These measures would make drivers feel like they’re in a city and not on a highway. A recent John Hopkins study says this would have substantial safety benefits.

With more than 7,500 miles of streets in the city of Los Angeles, they won’t all be rebuilt anytime soon. But with each road construction project, or each crash, we should be revising streets to make them safer for all road users.

The solution to traffic jam isn’t to make more space for cars. It’s to design the streets to be safe enough for alternatives such as biking, walking and mass transit, especially for the 50% of trips daily in Los Angeles that are less than three miles. The solution to protecting people dining outdoors isn’t crash barriers. It’s a street design that forces drivers to go slowly. The problem is carnage in the streets, and we know the solutions.

1. Why should the traffic death in Los Angeles be called “constant carnage”?
A.The traffic accidents happen quite often.
B.Too many people are killed in the traffic accidents.
C.The drivers’ speeding is to blame for the traffic death.
D.City leaders’ consistent choice contributes to the traffic death.
2. What does the word “trade-off” underlined in Paragraph 3 most probably mean?
A.Balance.B.Guideline.C.Conflict.D.Resolution.
3. According to the passage, which is a likely solution to the traffic problem?
A.To widen travel lanes.B.To add more crosswalks.
C.To arrange more traffic police.D.To punish speeding drivers.
4. Which would be the best title for the passage?
A.Drivers first or walkers first?B.Traffic death or constant carnage?
C.More warning signs or safer designs?D.More narrow lanes or speedy highways?
