Most of the cases were decided in state courts, when the railroads had the climate of the times on their sides. Government supported the railroad industry; the progress railroads represented was not to be slowed down by requiring them often to pay damages to those unlucky enough to be hurt working for them.
Court decisions always went against railroad workers. A Mr. Farwell, an engineer, lost his right hand when a switchman's negligence ran his engine off the track. The court reasoned that since Farwell had taken the job of an engineer voluntarily at good pay, he had accepted the risk. Therefore the accident, though avoidable had the switchman acted carefully, was a "pure accident". In effect a railroad could never be held responsible for injury to one employee caused by the mistake of another.
In one case where a Pennsylvania Railroad worker had started a fire at a warehouse and the fire had spread several blocks, causing widespread damage, a jury found the company responsible for all the damage. But the court overturned the jury's decision because it argued that the railroad's negligence was the immediate cause of damage only to the nearest buildings. Beyond them the connection was too remote to consider.
As the century wore on, public sentiment began to turn against the railroads— against their economic and political power and high fares as well as against their callousness toward individuals.
Which of the following is NOT true in Farwell's case？
A．Farwell was injured because he negligently ran his engine off the track.
B．Farwell would not have been injured if the switchman had been more careful.
C．The court argued that the victim had accepted the risk since he had willingly taken his job.
D．The court decided that the railroad should not be held responsible.

When you have a full tank of gas, park the car downhill. This will prevent any gas from coming out of the tank. Parking in areas of less or no sunlight helps prevent the gas from steaming that would occur if you parked in the hot sun. Your car will stay cooler, too, and that means less gas consuming work for the air conditioner once the engine is started.
Stay away from wide-track tyres if you want top mileage (汽车耗费1加仑油所行驶的路程) . Narrow-track tyres produce less friction and thus less rolling resistance. The same effect is achieved by adding three to five pounds above recommended pressure to each tyre: while this won't noticeably affect you car's sliding quality, it will increase tyre life and gas mileage.
Check tyre pressure often, especially when the weather turns cold. The difference between winter and summer tyre pressure can be as much as eight pounds. This could cost you two miles per gallon.
The main purpose of the passage is to tell us______.
A．how to drive faster
B．how to drive a car properly
C．how to make a car run smoothly
D．how to make your car consume less gas

Hybrid Cars
Have you pulled your car up to the gas pump lately and been shocked by the high price of gasoline？ As the pump clicked past $20 or $30, maybe you thought about trading in your car for something that gets better mileage. Or maybe you're worried that your car is contributing to the greenhouse effect.
The auto industry has the technology to address these concerns. It's the hybrid car. You're probably aware of hybrid cars because they've been in the news a lot. Most automobile manufacturers have announced plans to manufacture their own versions. What makes it a "Hybrid"？
Any vehicle is a hybrid when it combines two or more sources of power. In fact, many people have probably owned a hybrid vehicle at some point. For example, a moped (a motorized pedal bike) is a type of hybrid because it combines the power of a gasoline engine with the pedal power of its rider.
Hybrid vehicles are all around us. Most of the locomotives we see pulling trains are diesel-electric hybrids. Cities like Seattle have diesel-electric(以柴油发动机发电的) buses—these can draw electric power from overhead wires or run on diesel when they are away from the wires. Giant mining trucks are often diesel-electric hybrids. Submarines are also hybrid vehicles — some are nuclear-electric and some are diesel-electric. The gasoline-electric hybrid car is a cross between a gasoline-powered car and an electric car.
Hybrid Structure
You can combine the two power sources found in a hybrid car in different ways. One way, known as a parallel hybrid, has a fuel tank, which supplies gasoline to the engine. But it also has a set of batteries that supplies power to an electric motor. Both the engine and the electric motor can turn the transmission at the same time, and the transmission then turns the wheels.
By contrast, in a series hybrid the gasoline engine turns a generator, and the generator can either charge the batteries or power an electric motor that drives the transmission. Thus, the gasoline engine never directly powers the vehicle.
Why Build Such a Complex Car？
You might wonder why anyone would build such a complicated machine when most people are perfectly happy with their gasoline-powered cars. The reason is twofold: to reduce tailpipe emissions and to improve mileage. These goals are actually tightly interwoven.
Evolution of the Hybrid
The hybrid is a compromise. It attempts to significantly increase the mileage and reduce the emissions of a gas-powered car while overcoming the shortcomings of an electric car.
The Problem with Gas-powered Cars
To be useful to you or me, a car must meet certain minimum requirements. The car should be able to:
-Drive at least 300 miles (482 km) between re-fueling
-Be refueled quickly and easily
-Keep up with the other traffic on the road
A gasoline car meets these requirements but produces a relatively large amount of pollution and generally gets poor gas mileage. An electric car, on the other hand, produces almost no pollution, but it can only go 50 to 100 miles (80 to 161 km) between charges. And the problem has been that it is very slow and inconvenient to recharge.
A driver's desire for quick acceleration causes our cars to be much less efficient than they could be. You may have noticed that a car with a less powerful engine gets better gas mileage than an identical car with a more powerful engine. Just look at the window stickers(有图形或文字的粘贴标鉴) on new cars at a dealership for a city and highway mph comparison.
The amazing thing is that most of what we require a car to do uses only a small percentage of its horsepower! When you are driving along the freeway at 60 mph (96.6 kph), your car engine has to provide the power to do three things:

Engines of Change
The Holy Grail(圣杯) for Automakers
I am driving through downtown Washington, D.C., in a white GM minivan with friendly blue-bubble paper decorating the sides. It's emitting no toxic chemicals and the engine seems to purr(发出隆隆声) rather than growl. I am driving a hydrogen-powered automobile—so clean, you can drink from the exhaust pipe—and it's a smooth, energetic ride.
It's also the Holy Grail for automakers, environmentalists, political leaders—and, most important, drivers everywhere, whether or not we realize it yet. What's not to like about a vehicle that combats global warming, offers hope of weaning(使戒掉) the world off Mideast oil, and could save on fuel costs？ More than anything, though, the development of the hydrogen car, along with other alternatives, is a response to one unsettling fact: The world will one day run out of oil. And that day may arrive sooner than most of us would think.
Industry experts at the Association for the Study of Peak Oil and Gas (ASPO) predict that by 2008, we may have extracted half the available global supply of oil. While it took us the better part of the last century to reach this halfway point, it will take significantly less time to consume the rest. With more industrialized countries, more cars, trucks and buses, and more demand than ever for home heating and appliances—just think China—oil could reach depletion more quickly than we once assumed. So the race is underway to find affordable fuel alternatives, as well as new ways to conserve our remaining oil.
For car manufacturers and a growing number of consumers, the future is now-in the form. of the latest generation of hybrid vehicles. Toyota, Honda and Ford have led the charge with technology that pairs a small gasoline engine with an electric motor that actually powers the car without high levels of pollution. The electric motor and gasoline engine is more efficient than a combustion(燃烧) engine. According to the Alliance to Save Energy, in 2004, SUV drivers spent about $1,225 on fuel, while passenger cars cost $976 to run. Hybrid drivers only spent between $350 and $450.
Also, hybrids have solved a big drawback of energy-efficient electric cars, which need to be recharged regularly literally plugged into a power source. Hybrids like Honda's Insight, Civic and Accord, and Toyota's Prius, charge the battery as you drive. Plus, some can travel more than 600 miles on a tank of gas.
To lure people to buy these cleaner, more efficient cars—hybrids, the federal government is offering owners a one-time tax deduction. Local governments are offering incentives too. Hybrid owners in Los Angeles receive parking exemptions; in Connecticut, residents whose energy-efficient cars get at least 40 miles per gallon are exempt from the sales tax on the car; Pennsylvania owners are eligible for a $500 discount at purchase; and in Virginia, hybrid drivers can take advantage of the HOV (high-occupancy vehicle) lane—no matter how many passengers are on board.
According to Bradley Berman, editor of HybridCars.com, 88,000 of these automobiles were sold in the United States last year—that's nearly double the previous year and about ten times as many sold in 2000. This year alone, the chic(时尚的) Prius is on track to sell some 45,000, despite six-month waiting lists.
Reducing U.S. Oil Consumption
Even as more hybrid cars hit the road, the technology is a key element in an exciting new project, one that could hasten our transition to a hydrogen-fuel economy. The Rocky Mountain Institute (RMI), a nonprofit organization dedicated to energy policy, has launched a research center with the sole purpose of creating the "Hypercar." This vehicle's design is what sets it apart. Hypercars are formulated to make the most of an ultra-light construction, low-drag aero-dynamics and hybrid-electric drive trains to achieve much greate
