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.
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.
B. $ 60.
C. $ 131.
D. $ 80.
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.
B. excited
C. amused
D. suited
Some plants get so hungry they eat flies, and even small frogs. What's more amazing is that these plants occur naturally (in special environments) in every state. In fact, they're found on every continent except Antarctica.
You've probably seen a Venus' flytrap -- a small plant, which grows 6 to 8 inches tall in a container. At the end of its stalks (茎) are leaves that act like traps (陷阱). Inside each trap is a lining of tiny hairs. When an insect lands on them, the traps suddenly shut. Over the course of a week or so, the plant feeds on its catch.
The Venus' flytrap is just one of more than 500 species of meat-eating plants, says Barry Meyers-Rice, the editor of the International Carnivorous Plant Society's Newsletter. He states although you might have read some science-fiction stories, no meat-eating plant does any danger to humans.
Barry says a plant is meat-eating, only if it does all four of the following: "attract, kill, digest, and absorb" some form of insects. Meat-eating plants look and act like other green plants -- well, most of the time.
All green plants make sugar to produce food. What makes meat-eating plants different is their special leaves, which need insects for one reason: nitrogen (氮). Nitrogen is a nutrient that they can't obtain any other way. Why?
Almost all green plants on our planet get nitrogen from the soil. Meat-eating plants can't. They live in places where nutrients are hard to get from the soil because of its acidity. So they've come to rely on getting nitrogen from insects and small animals. In fact, nutrient-rich soft is poisonous to meat-eating plants. Never fertilize (施肥) them! But don't worry, either, if they never seem to catch any insects. They can survive, but they'll grow very slowly.
