43．A．light B．power C．plug D．electricity——青夏教育精英家教网—

阅读下列短文，从每题所给的四个选项（A、B、C和D)中，选出最佳选项。

　　The United States is the world's largest consumer of energy．We use electricity, gas and oil to light and heat our buildings and run our cars．The demand for power is growing．But we may not need to build new power plants for or find more oil．The best way to increase our supply of energy is to be more efficient．

　　Did you know that when you leave your video－game console on, it consumes more electricity than two refrigerators? Or that those funny－looking, twisty bulbs use 75％ less power than traditional light bulbs? We have the tools to save money, reduce pollution and even help our planet, simply by wasting less energy．

　　As President, Barack Obama plans to make energy efficiency in American a major goal．He has pledged to cut 15％ of all energy used by the Federal Government．In a speech, he called for 75％ of government office buildings to be updated for better efficiency．He pointed out that energy－efficient buildings and homes will save consumers billions of dollars on energy bills．An "extra benefit", he added, will be "a cleaner, safer planet．"

　　Gas, coal and oil are called fossil fuels．Fossil fuels have been the world's main source of energy for hundreds of years．But burning them releases dirty gases, which cause pollution．

　　There are two main ways to save energy．The first is to use more efficient machines．Hybrid cars use less gas．New appliances are designed to use less electricity．Today's refrigerators are three times more efficient than those before 1973．Laptop computers consume much less energy than desktop computers．

　　The second is to use machines more productively．According to the US Department of Energy, in the average home, 75％ of the electricity used to power electronic equipment is standby power(备用电源)．That means power flowing to plugged－in appliances whether or not they are being used．

　　Homeowners can avoid wasting power by pulling the plug on appliances when they are not in use．Efficiency experts argue that today's best techniques could cut US oil and gas use in half, and reduce our electricity use by three－fourths．

(1)

The underlined word "pledged" in Paragraph 3 probably means ________ ．
[　　]

阅读理解

　　After years of research and testing, the hybrid car was developed and put on the market．It’ san interesting and exciting new improvement in today's world as we look for better ways to protect the quality of the air we breathe and conserve(保持)our natural resources．

　　The quality of our air is affected by many different things．But one of the largest sources of air pollution is the burning of fossil fuels such as coal and gasoline which is used to power a car's engine．The EPA has set national standards to help control the level of harmful pollutants sent off into the air ，and the automobile industry has acted by producing a hybrid car that uses less gas and therefore causes less pollution．

　　A hybrid car is a combination of a regular car that runs on gasoline and an electric car that is battery powered．Some people tend to think that since the hybrid car is partially electric, you have to plug(接通电源)it in to charge it．But that's not how it works．The 144-volt battery pack is actually recharged through the energy that is produced when the car's brakes are used．This is referred to as "regenerative braking", because it generates electricity．

　　Although the hybrid car still runs on gasoline most of the time, this helps it use less gas than a regular car．When the driver stops at a traffic light, the engine automatically shuts off to save fuel．Then, as soon as the driver puts the car in gear and touches the gas pedal, the engine starts backup．

　　Have you ever ridden in a car with someone who ran out of gas? That probably wouldn't happen if you were riding in a hybrid car．It flashes a warning on its computer screen that says, "I am low on gas"．When it completely runs out, the warning reads，"YOU ARE NOW OUT OFGAS!” Then the electric power supply kicks in to let the driver travel a few more miles to a gas station．

(1)

Which of the following is TRUE according to the passage?
[　　]
A．	The hybrid car will be put on the market in the near future．
B．	The hybrid cars run faster and are much safer than regular cars．
C．	When the hybrid car stops at a traffic light, the driver will get a warning．
D．	The burning of fossil fuels is one of the largest sources of air pollution．

(2)

According to the passage, the word "hybrid" refers to ________．
[　　]
A．	a high-tech discovery
B．	energy saving
C．	a new invention
D．	a combination of two things

(3)

"Regenerative breaking" is an important process of the hybrid car because ________．
[　　]
A．	it allows the car to come to a quick stop
B．	it gives the driver a smoother ride
C．	it produces energy to charge the battery
D．	it can control the speed of the car

(4)

Which of the following is right about the EPA?
[　　]
A．	They have designed hybrid cars to reduce air pollution．
B．	They have declared the burning of fossil fuels to be illegal．
C．	They set important guidelines that help control pollution．
D．	Their main purpose is to protect endangered plants and animals．
