Some years ago, on a hot summer day in south Florida, a little boy decided to go for a swim in the cold swimming hole behind his house.

In a hurry to dive into the cool water, he did not realize an alligator（短吻鳄）was swimming towards the shore. His mother in the house, looking out of the window, saw the two as they got closer and closer together. In fear, she ran towards the water, yelling to the son as loudly as she could.

It was too late. The alligator reached him.

From the dock, the mother grabbed her little boy by the arms just as the alligator got his legs. That began an incredible tug of war（拔河）between the two. The alligator was much stronger than the mother, but the mother would not let go. A farmer happened to drive by, heard her screams, ran from his truck, and shot the alligator.

Amazingly, after weeks and weeks in the hospital, the little boy survived. His leg were extremely scarred by the animal’s attack, and on his arms were scratches (抓痕) from mothers’ fingernails where she had tried to hang on to the son she loved.

The newspaper reporter who interviewed the boy asked if he would show him his scars. The boy lifted his pant legs . And then, he proudly said to the reporter: “But look at my arms. I have great scars on my arms, too. I have them because my mom would not let go.”

You and I can identify with (理解) that little boy. We have scars, too. No, not from alligator, or anything quite so dramatic . But the scars of a painful past. Some of those scares are ugly and have caused us deep regret.

But some wounds, my friend, are because someone has refused to let go. In your struggle, maybe someone has been there holding on to you.

Electric cars are dirty. In fact, not only are they dirty, but they might even be more dirty than their gasoline-powered cousins.

People in California love to talk about “zero-emissions (排放) vehicles”, but people in California seem to be clueless about where electricity comes from. Power plants mostly use fire to make it. Apart from the few people who have their roofs covered with solar cells, we get our electricity from generators (发电机). Generators are fueled by something----usually coal, oil, but also by heat generated in nuclear power plants. There are a few wind farms and geothermal (地热) plants as well, but by far we get electricity mainly by burning something.

In other words, those “zero-emissions” cars are likely coal-burning cars. Because the coal is burned somewhere else, it looks clean. It is not true. It's as if the California Greens are covering their eyes----“If I can't see it, it's not happening.” Gasoline is an incredibly (极其) efficient way to power a vehicle; a gallon of gas has a lot of energy in it. But when you take that gas (or another fuel) and first use it to make electricity, you waste a nice part of that energy, mostly in the form of wasted heat--at the generator, through the transmission lines, etc.

A gallon of gas may drive your car 25 miles. But the electricity you get from that gallon of gas won't get you nearly as far---so electric cars burn more fuel than gasoline-powered ones. If our electricity came mostly from wind or geothermal, or solar, then an electric car truly would be clean. But for political, technical, and economic reasons, we don't use much of those energy sources.

In addition, electric cars' batteries which are poisonous for a long time will eventually end up in a landfill (垃圾填埋场). And finally, when cars are the polluters, the pollution is spread across all the roads. When it's a power plant, though, all the junk is in one place. Nature is very good at cleaning up when things are not too concentrated, but it takes a lot longer when all the garbage is in one spot.

1.Which of the following words can replace “be clueless about” in Paragraph 2?

A. be familiar with. B. fail to understand.

C. be curious about. D. show their interest in.

2.The electricity we get from a gallon of gas may make our car run _________.

A. at least 25 miles B. more than 25 miles

C. less than 25 miles D. as far as 25 miles

3.In the author’s opinion, compared with cars using gas, electric cars are more __________.

A. harmful B. expensive

C. efficient D. environmentally-friendly

4.It can be inferred from the passage that __________.

A. electric cars’ batteries are no longer poisonous in the landfill

B. electric cars are not clean since we get electricity mainly by burning something

C. zero-emissions vehicles should be chosen to protect our environment

D. now electric cars are used more than their gasoline-powered cousins

One evening two young man were walking in the street together. They tried to find a chance to steal everything. The clock struck twelve. Most of the people were in bed. Quickly they came to a house and it seemed everyone in the house had fallen asleep. Standing at the front gate, one man whispered in English to the other at a low voice, “You wait here and I’ll go around to the back door and then get into the house.” Suddenly out of the house ran a dog, barked at them. The two men was very frightened and ran away as fast as possibly. They didn’t stop until they get to a lonely place. The man said to the other in a surprise, “It’s too bad, but I hadn’t thought what the dog could understand English.”

Children in the United States eat too much pizza that some researchers now argue the food should join the ranks of sugary drinks and fast food for the harm they do to health．

In a new study, the researchers found that pizza is a large source of calories, saturated fat(饱和脂肪)and salt in children’s diets．Children should not eat more than two slices of pizza for a meal，and should pair that with salad, rather than with another high-calorie food，the researchers concluded．

“Parents should aim to control pizza consumption(消费), particularly as a snack where it was shown to have a very adverse impact on children, and they should put their pizza dollars toward healthier brands．”Said Lisa Powel, director of the Illinois Prevention Research Center．

Pizza has become a matter of focus in recent years for researchers who look at the meals children eat, rather than the nutrients within them．Studies have found pizza is among the greatest sources of calories for children．

“Since pizza remains a common part of children’s diet, we need to make ‘healthy’ pizza．”Powel said．To make pizza healthier, food producers should reduce its saturated fat and salt, and increase its whole grain content,” she said．

Whether or not pizza is harmful enough to be picked out as an unhealthy food, the study attracts attention to a larger issue with the modern American lifestyle, said Alexis Tindall, who was not involved in the flow research. “Many foods are eaten too frequently and in large sizes,” said Tindall．To solve the problem, people don’t have to give up eating pizza, but instead, they can eat smaller and healthier pizza，”she said．

“Make it at home, instead of ordering it out where you don’t have any control over how it’s made.” Tindall said. “When we make it at home, we can choose healthier ingredients，increase the vegetables, reduce fat, and put in less cheese．Pizza doesn’t have to be just pepperoni(意大利辣香肠)and cheese．”

1.According to the research, children shouldn’t eat ．

A．more than two slices of pizza in a day

B．two slices of pizza for a meal

C．pizza along with salad

D．more pizza with French fries

2.Powel suggests healthier pizza should be made ．

A．with more ingredients B．with less salt

C．in smaller sizes D．at home

3.The last sentence of the passage implies that pepperoni and cheese ．

A．are necessary ingredients of pizza

B．are not the only healthy ingredients of pizza

C．should all be replaced with healthier ingredient．

D．should be reduced by adding healthier ingredients．

4.What is the best title for the passage?

A．Pizza—a real junk food!

B．How to prepare better meals for your kids?

C．Discover the harm of eating pizza

D．Bring in healthier pizza for Americans
