There’s gas e________ somewhere. Can you smell it?

B

China is going green．In order to reduce air pollution and oil shortages, carmakers have announced their plans to develop hybrid vehicles (混合燃料汽车) for the Chinese market．Toyota’s hybrid car Prius will be ready to drive in China this week．Let’s have a look at the new car．

Any vehicle is a hybrid run on a rechargeable battery and gas．Hybrid cars have special engines, which are smaller than traditional gas engines．The gasoline engine provides 99 percent of the power when the car is going at a steady speed. A specially designed battery motor provides extra power for running up hills or when it needs to speed up．

Step into a Prius, and turn on the engine．The first thing you notice is that it is quieter than a traditional car．At this point, the car’s gas engine is at rest．The electric motor will provide power until the car reaches about 24km/h．If you stay at a low speed, you are effectively driving an electric car, with no gas being used, and no waste gas given off．

The computer decides when to use the gas engine, when to go electric, and when to use a combination of the two．If you go over 24km/h, when you step on the gas pedal (油门), you are telling the computer how fast you want to go．

The electric motor recharges automatically using a set of batteries．And when driving at a high speed, the gas engine not only powers the car but also recharges the batteries．When you use the brake, the electric motor in the wheels will work like a generator (发电机) to produce electricity to recharge the batteries．As a result, the car’s batteries will last for around 200,000 miles．

A．there will be more and more green land in China  

B．China’s new cars are combinations of different green models

C．China is still young and lacking in experience

D．the environment is getting better in China

Long bus rides are like television shows. They have a beginning, a middle, and an end with commercials （商业广告） thrown in every three or four minutes. The commercials are unavoidable. They happen whether you want them or not. Every couple of minutes a billboard glides by outside the bus window. "Buy Super Clean Toothpaste. ""Drink Good Wet Root Beer." "Fill up with Pacific Gas." Only if you sleep, which is equal to turning the television set off, are you spared the unending cry of "You Need It! Buy It Now!"

The beginning of the ride is comfortable and somewhat exciting, even if you’ve traveled that way before. Usually some things have changed—new houses, new buildings, sometimes even a new road. The bus driver has a style of driving and it’s fun to try to figure it out the first hour or so. If the driver is particularly reckless （鲁莽的） or daring, the ride can be as thrilling （惊心动魄的） as a suspense story. Will the driver pass the truck in time? Will the driver move into the rightor the lefthand lane? After a while, of course, the excitement dies down. Sleeping for a while helps pass the middle hours of the ride. Food always makes bus rides more interesting. But you’ve got to be careful of what kind of food you eat. Too much salty food can make you very thirsty between stops.

The end of the ride is somewhat like the beginning. You know it will soon be over and there’s a kind of expectation and excitement in that. The seat of course, has become harder as the hours have passed. By now you’ve sat with your legs crossed, with your hands in your lap, with your hands on the armrests even with your hands crossed behind your head. The end comes just at no more ways to sit.
