China_is_going_green. In order to reduce air pollution and oil­shortages, automobile manufacturers 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 when it combines two or more sources of power. Hybrid cars run off a rechargeable battery and gasoline. Hybrid cars have special engines, which are smaller than traditional gasoline engines. They run at 99 percent of their power when the car is cruising (匀速行驶). A specially designed battery motor provides extra power for running up hills or when extra acceleration is needed.
Step into a Prius, and turn on the engine. The first thing you notice is how much quieter it is than a traditional car. At this point, the car's gasoline engine is dormant (休眠). The electric motor will provide power until the car reaches about 24 km/h. If you stay at a low speed, you are effectively driving an electric car, with no gasoline being used, and no waste gas gives off.
The onboard(车载的) computer makes the decision about when to use a gas engine, when to go electric, and when to use a combination of the two. If you go over 24 km/h, when you step on the gas pedal (油门), you are actually telling the computer how fast you want to go.
The electronic motor recharges automatically using a set of batteries. When driving at high speed, the gasoline engine not only powers the car, but also charges the batteries. Any time you use the brake, the electric motor in the wheels will work like a generator and produce electricity to recharge the batteries. As a consequence, the car's batteries will last for around 200,000 miles.

Anchors(新闻节目主持人)on China Central Television(CCTV) will need to do some fast talking to replace the popular English acronyms(首字母缩略词)they are now banned from using. Shanghai Daily reports that “anchors at China Central Television have been banned from saying the English acronyms NBA, CBA, GDP, and the like in their programs.”

    The replacement for those handy acronyms? Chinese presenters must use the full Chinese name, standardized by the State Administration of Radio, Film and Television.

    Although CCTV(oops, we mean China Central Television) presenters must already have a score of at least 94 in their government-rated oral mandarin proficiency(普通话水平)exam, saying the full name of organizations like the CBA and WTO---10 and 6 characters’ long respectively---is sure to challenge even the most skillful anchors. CCTV sports anchor Sun Zhengping tells Shanghai Daily, “A full Chinese explanation of the English initials must be followed if my tongue slips. It is a little troublesome but a necessary one because not every member of the audience can understand the initials.”

    Although the government isn’t giving any official explanation for the shift, it is believed to have something to do with a proposal by Huang Youyi, director of the China International Publishing Group, at March’s NPC meeting. In his speech, Huang said, “With more and more publications mixing Chinese with English, measures and regulations should be adopted to avoid English invading Chinese. If we don’t pay attention and don’t take measures to stop the expansion of mixing Chinese with English, Chinese won’t be a pure language in a couple of years.”

    Although China is far from the first country to take measures to protect local languages, acronyms are more about saving time than they are about corrupting(破坏)a language, we would think. Good luck to the CCTV anchors.

3.What’s Huang Youyi’s purpose?

E.                      Using full English names instead of short forms.

F.                      Translating Chinese terms into proper English.

G.                     Avoiding Chinese words being mixed into English.

H.                     Keeping our mother tongue a pure language.

4.What’s the main idea of the last paragraph?

I.                        China has fallen behind in the matter of protection of its language.

J.                       The ban is not necessary.
