[主观题]

It was once considered a good idea to keep the car engine running on idle for a minute or two following a cold start.Today,with modern technology,the opposite is true.An engine operating under road conditions will warm up faster and run more efficiently than the one that has been idling,as this just burns up gas(on average about a gallon an hour).If possible,when you have a full tank of gas,park the car facing downhill,as this will prevent any gas from leaking out of the tank.Parking in areas of little or no sunlight helps prevent evaporation(蒸发)of the gas which would occur if you parked in the hot sun.Your car will stay cooler,too,and this means less gas is consumed for the air conditioner once the engine is started.Stay away from wide-track tires if you want top mileage for your dollar.Narrow-track tires produce less friction and thus rolling resistance.The same effect is achieved by adding three to five pounds above recommended pressure to each tire while this won't noticeably affect your car's mobility,it will increase the life of your tires and gas mileage.Check tire pressure often,especially when the weather turns cold.The difference between winter and summer tire pressure can be as much as eight pounds.This could cost you two miles per gallon.1.The main purpose of the passage is to tell us（）.A.how expert drivers try to save gasB.how to drive a car properlyC.how to make a car run smoothlyD.how to make your car consume less gas2.According to the passage,keeping the engine run idly（）.A.will just waste gasB.will warm it up more quicklyC.will make it work more efficientlyD.is necessary in cold weather3.Parking your car in a cool place（）.A.will take it longer to warm up the engineB.means less gas consumption for the air conditionerC.prevent any gas from coming out of the tankD.helps start your car more easily4.Wide-track tires（）.A.won't noticeably affect your car's sliding qualityB.can increase tire lifeC.will increase rolling resistanceD.helps attain top gas mileage5.Tire pressure changes（）.A.when wide-track tires are usedB.when narrow-track tires are usedC.in different weather conditionsD.in different road conditions

听力原文： Foreign pilots are to be drafted into Chinese airlines to relieve the shortage of qualified flyers. CAAC statistics show that about 11, 000 pilots are employed to fly more than 770 aircraft operated by the major Chinese commercial airlines, which industry experts consider as inadequate to cope with the rocketing demand for passenger services. Around 145 new aircraft will be delivered for operation this year in China, and the new planes alone will push aircraft numbers beyond the capacity of training schools to supply new pilots. (6) Industry experts estimate China needs between 1, 200 and 1, 600 new pilots every year since 2000, while the nation's major training schools for commercial airline pilots can provide a maximum of 600 pilots annually.

Industry. experts estimate China needs between ______ and ______ new pilots annually since 2000.

A．770; 1,200

B．1,200; 1,300

C．1,200; 1,600

听力原文：In going over your finances, one of the things I've noticed is, you have a lot of
equity in your home—your home is worth quite a bit of money. Instead of taking out credit cards or finding some other loan to pay your daughter's education expenses, you should consider getting a home equity line of credit. What that means, basically, is that, instead of a loan, you get a credit card that's approved up to a certain amount. You use that card if and when you need it—five hundred dollars here, a thousand dollars there. You don't need to borrow all the money all at once—which then puts you on track to make payments and that sort of thing. If you don't use your line of credit, you owe nothing. But it's there when you need it. And because of your house, you're a perfect candidate for a home equity line of credit— I think you'll like it a lot more than a loan.

What is the speaker mainly describing？

A．Qualifying for a loan

B．Managing personal debt

C．Getting a line of credit

D．Avoiding credit card fees

Key James, Secretary of Health and Human Resources in the Virginia State government, loves
to turn the tables on those who don't think it's possible to be middle-class, conservative, educated and still be truly black. Once, during an abortion debate, a woman in the audience angrily told James she was so middle-class she didn't have a clue about real African American life. "If you understood what these women go through," the woman said, "you would realize that abortion is their only choice."

James then asked the woman to consider a poor black mother on welfare. She already has four children and an alcoholic husband who has all but abandoned the family. Now she discovers another child is on the way. "How would you counsel that woman？" asked James.

"Have an abortion," the woman responded. "That child would have a very poor quality of life."

"I have a vested interest in your answer," James said. "The woman I described was my mother. I was the fifth of six children born into poverty. And, in case you're interested, the quality of my life is just fine!"

Kay James ______.

A．is not a black

B．is a poor black mother

C．has five brothers and sisters

D．has a hard life
