氢气可被用作清洁能源，但它的制取、存储和运输都很困难。科学家开发出一种用糖类制取氢气的新技术，有望解决这几大问题。以这项技术为基础，未来的氢动力汽车将携带易于存储的糖类，如淀粉，其化学式是(C₆H₁₀O₅)n。科学家使用由多种特殊的酶组成的混合物，将淀粉和水转变成CO₂和H₂的混合气体，将CO₂除去后，H₂进入燃料电池产生电力，驱动汽车前进。燃料箱容量为55升的汽车可携带约27千克淀粉和21千克的水，完全转变，可以产生4千克氢气，其余为CO₂。根据以上材料，请回答下列问题：

(1)利用该项技术，汽车运动时时的机械能最终由下列哪种能量转化而来

A．化学能 B．太阳能 C．电能 D．热能

(2)混合物中的酶具有高效性、多样性和性。

(3)请根据质量守恒定律配平淀粉和水反应的化学方程式

(C₆H₁₀O₅)n+ H₂O H₂+ CO₂

(4)若一辆氢动力汽车正常行驶时，功率是70千瓦，氢气的热值是1.4×10⁸焦／千克，燃料电池的能量转化效率是50%，在阻力不变和不考虑其它能量损耗时，要使该车能正常行驶，汽车每小时至少消耗氢气千克

Patricia asked for the cheapest car available at Acme Car Rental. She needed a car for 48

hours. Because it was the weekend,there was only one car available at the moment-an SUV.

Patricia was an environmentalist. SUVs,which are big cars consuming a lot of gasoline,offended

her greatly.

But she needed something to get to Baker,a town that was 100 miles from the small airport.

So she went, RentMe instead. "I need a car for 48 hours," she said," and I don't want an SUV.

I want something cheap. "They told her they had just the vehicle for her,a 1998Toyota. Thirty

dollars a day,including insurance and other incidental fees. All she had to do was to pay forher

own gasoline. Patricia was very pleased. Thirty dollars a day was a good rate even for a weekday.

She signed all the paperwork,and they gave her the keys.

The Toyota was a 4-speed,4-cylinder,2-door beauty,the paint,tires,and the interior were like

the new. It was comfortable, even though the air-conditioner was not the frostiest(结霜的) . She

got in and drove north. It was a two-lane road all the way to Baker,with only one town between

the airport and Baker. That town was Noms,40 miles from Baker.

Patricia didn't make it to Norris. The car refused to run 30 minutes after she had been driving

it. Fortunately,her cell phone was able to connect back to the RentMe desk. "My car stopped

running. and I'm out here in the middle of nowhere in the hot sun! " she said.

"That doesn't make any sense," said the clerk."You did put gas in the car before you left town,

didn't you? "

"No. Of course not ! " yelled Patricia. " Why would Iput gas in the car before I even got out

of town?" "Well,why do you think you got such a good

rate-we save money by having the customer gas up instead of us having to put gas in the car. "

"I was in a hurry,"said Patricia.

"Well,sometimes you pay a price for being in a hurry," said the clerk. " We'II send a man out

with some spare gas for you:if you'd like. ,,"

Of course l'd like , " said Patria.ia. " How long willit be?"

The clerk told her it would be within the hour. He didn't tell her that there would be a $ 50

service charge for delivering the gas,or that the 3 gallons of fuel would cost her $ 7 a gallon. She

would get that bad news when she retumed the car to the airport.

1. Why didn't Patricia want to rent an SUV?

A. Because it was a big car that would need a lot of gasoline.

B. Because she failed to carry enough money with her.

C. Because she was not used to driving suc, h a big car.

D. Because it was not easy to drive since it was so old.

2. How much would Patricia have to pay at least when she returned the car to the airport?

A. $ 161.

B. $ 60.

C. $ 131.

D. $ 80.

3. Which of the following is true?

A. Patricia did put gas in the car before she left town.

B. The air-conditioner of the Toyota was functioning perfectly.

C. The car broke down halfway there and needed repairing.

D. Patricia was quite satisfied with the price at first.

4.The underlined word "offended" in the first paragraph means " "
