Question

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．
