21、A three-year study comparing three different treatment options for tooth decay (腐烂) in children’s teeth has found no evidence to suggest that conventional fillings are more telling than sealing (封闭) decay in teeth, or using prevention techniques alone, in stopping pain and infection from tooth decay.
The FiCTION trial, the largest of its kind to date, also found that 450 children who took part in the study experienced tooth decay and pain, regardless of which kind of dental treatment they received.
Professor Nicola Innes, Chair of Paediatric Dentistry at the University of Dundee, said, “Our study shows that each way of treating decay worked to a similar level but that children with tooth decay at a young age have a high chance of experiencing toothache however the dentist manages the decay. From our trial, the best way to manage tooth decay is not by drilling it out or sealing it in, but it’s by preventing it in the first place.”
During the study, one of three treatment approaches was then chosen randomly for each child’s dental care for the duration of the trial for three years. The first approach aimed to prevent new decay by reducing sugar intake, ensuring twice-daily brushing with fluoride toothpaste (含氟牙膏). The second option involved drilling out tooth decay. For the third treatment strategy, tooth decay was sealed in to stop it progressing.
Of all three different ways of treating decay, sealing-in with preventive treatment was the most likely to be considered the best way of managing children’s decay if society is willing to pay a minimum of £130 to avoid an episode of pain or infection.
Professor Anne Maguire, Chair of Preventive Dentistry said, “The FiCTION findings have focused again on the need to prevent dental decay. The good news is that tooth decay can be prevented. Brushing your teeth with fluoride toothpaste, especially before bedtime, avoiding sugary drinks and snacks between meals and seeing a dentist regularly are all small habits that can help boost the overall health of your teeth.”
【1】What does the underlined word “telling” in paragraph 1 mean?
A．Popular.
B．Pessimistic.
C．Expensive.
D．Effective.
【2】What does the study advise us to do?
A．Let tooth decay fall out naturally.
B．Drill tooth decay out at the dentist’s.
C．Prevent tooth decay as early as possible.
D．Have conventional fillings to manage tooth decay.
【3】Why were the three treatment approaches chosen randomly in the study?
A．To use different ways.
B．To get precise findings.
C．To explore other fields.
D．To analyse more reasons.
【4】What does Professor Anne Maguire want to tell us?
A．We should take good care of our teeth.
B．Children shouldn’t eat any snacks.
C．The study’s findings may be one-sided.
D．He will do further research on tooth decay.
22、 Since English biologist Charles Darwin (1809 –1882) published On the Origin of Species in 1859, scientists have vastly improved their knowledge of natural history. However, a lot of information is still the subject of speculation, and scientists can still only make educated guesses at certain things.
One subject that they guess about is why some 400 million years ago, animals in the sea developed limbs (肢) that allowed them to move onto and live on land.
Recently, an idea that occurred to the US paleontologist (古生物学家) Alfred Romer a century ago became a hot topic once again.
Romer thought that tidal (潮汐的) pools might have led to fish gaining limbs. Sea animals would have been forced into these pools by strong tides. Then, they would have been made either to adapt to their new environment close to land or die. The fittest among them grew to accomplish the transition (过渡) from sea to land. Romer thought that tidal pools might have led to fish gaining limbs.
Romer called these earliest four-footed animals “tetrapods” (四足动物). Science has always thought that this was a credible theory, but only recently has there been strong enough evidence to support it.
Hannah Byrne is an oceanographer (海洋学家) at Uppsala University in Sweden. She announced at the 2018 Ocean Sciences Meeting in Oregon, US, on Feb 15 that by using computer software, her team had managed to link Romer’s theory to places where fossil deposits (化石沉积) of the earliest tetrapods were found.
According to the magazine Science, in 2014, Steven Balbus, a scientist at the University of Oxford in the UK, calculated that 400 million years ago, when the move from land to sea was achieved, tides were stronger than they are today. This is because the planet was 10 percent closer to the moon than it is now.
The creatures stranded in the pools would have been under the pressure of “survival of the fittest”, explained the UK’s University of Bangor ocean scientist Mattias Green. As he told Science: “After a few days in these pools, you become food or you run out of food … the fish that had large limbs had an advantage because they could flip (空翻) themselves back in the water”.
As is often the case, however, there are others who find the theory less convincing. Cambridge University paleontologist Jennifer Clark, speaking to Nature magazine, seemed unconvinced. “It’s only one of many ideas for the origin of land-dwelling (陆地栖息的) tetrapods, any or all of which may have been a part of the answer,” she said.
【1】Who first proposed the theory that fish might have gained limbs because of tidal pools?
A.Charles Darwin. B.Alfred Romer. C.Hannah Byrne. D.Steven Balbus.
【2】Why were tides stronger 400 million years ago than they are today according to Steven Balbus?
A.There were larger oceans. B.Earth was under greater pressure.
C.The moon gave off more energy. D.Earth was closer to the moon.
【3】What does the underlined word “stranded” in Paragraph 8 mean?
A.Trapped. B.Settled. C.Survived. D.Adapted.
【4】What is the focus of the article?
A.The proposal of a new scientific theory.
B.The arguments over a scientific theory.
C.Some new evidence to support a previous theory.
D.A new discovery that questions a previous theory.

DOGS DRIVE CAR
Auckland, New Zealand
After two months of learning, Monty, and Porter were able to drive an automobile around a racetrack. “We wanted to prove how smart rescue dogs are,” animal behaviorist Mark Vette says. Vette first used voice commands and treats to teach the dogs how to turn a steering wheel and how to change gear(换挡).
The dogs’ ride only accelerated up to 7.5 miles an hour, and trainers could stop the auto using a remote control.
GOLDEN ZEBRA
Kailua-Kona, Hawaii
Zoe the zebra’s markings are special. The animal has white and golden stripes. Zoe’s appearance resulted from a rare condition called amelanosis(黑色素缺失症). Her body doesn't make enough melanin, the substance in an animal’s skin and hair cells that produces color. “Only 25 other golden zebras are known to exist in the world,”says Ann Goody, who runs the wildlife refuge where Zoe lives. In the wild, life may be difficult for animals with amelanosis because predators(捕猎者) can easily spot them. But Zoe is protected at her refuge.
COCKATOO MAKES TOOLS
Vienna, Austria
When Figaro the cockatoo spots food lying just out of reach from his cage, he builds a tiny wooden tool to sweep the tasty prize in his way.
The bird first revealed his talent when a stone he was playing with rolled out of his cage. The cockatoo couldn’t reach the stone. So he flew away and returned with a small branch, slipping it through the fence to slide the stone toward him.
Wondering if he would do it again, scientists placed a nut exactly where the stone had been. This time, Figaro pulled out a small piece of wood in his cage and dragged the nut toward him.
【1】If Zoe the zebra is set free in the wild, she will ________.
A. meet no natural predators
B. not get along with other zebras
C. manage to make enough melanin
D. be easily found for her appearance
【2】What’ s special about Figaro the cockatoo?
A. He’ s particular about his food.
B. He’s extremely fond of stones.
C. He’s good at drawing support from outside forces.
D. He can tell the difference between stones and nuts.
【3】What is the text mainly about?
A. Amazing animals.
B. Ways to help animals.
C. Animals’ unique talents.
D. Tips on training animals.
24、
At Denver there was an crowd of passengers into the coaches（车厢） on the eastbound B. & M. express. In one coach there sat a very pretty young woman dressed in elegant taste and surrounded by all the luxurious comforts of an experienced traveler. Among the newcomers were two young men, one of handsome presence with a bold, frank face expression and manner; the other a ruffled, glum-faced person, heavily built and roughly dressed. The two were handcuffed（拷上手铐） together.
As they passed down the aisle of the coach the only available seat offered was a reversed one facing the attractive young woman. Here the linked couple seated themselves. The young woman's glance fell upon them with a distant, swift disinterest; then with a lovely smile brightening her face and a tender pink tingeing（稍加染色，影响） her rounded cheeks, she held out a little gray-gloved hand. When she spoke her voice, full, sweet, and deliberate, proclaimed that its owner was accustomed to speak and be heard.
"Well, Mr. Easton, if you will make me speak first, I suppose I must. Don't you ever recognize old friends when you meet them in the West?"
The younger man aroused himself sharply at the sound of her voice, seemed to struggle with a slight embarrassment which he threw off instantly, and then clasped her fingers with his left hand.
"It's Miss Fairchild," he said, with a smile. "I'll ask you to excuse the other hand; "it's otherwise engaged just at present."
He slightly raised his right hand, bound at the wrist by the shining "bracelet" to the left one of his companion. The glad look in the girl's eyes slowly changed to a bewildered horror. The glow faded from her cheeks. Her lips parted in a vague（含糊，犹豫）, relaxing distress. Easton, with a little laugh, as if amused, was about to speak again when the other forestalled him. The glum-faced man had been watching the girl's face expression with veiled glances from his keen, shrewd eyes.
"You'll excuse me for speaking, miss, but, I see you're acquainted with（认识，熟悉） the officer here. If you'll ask him to speak a word for me when we get to the pen（围栏，监狱） he'll do it, and it'll make things easier for me there. He's taking me to Leavenworth prison. It's seven years for cheating."
"Oh!" said the girl, with a deep breath and returning color. "So that is what you are doing out here? An officer!"
"My dear Miss Fairchild," said Easton, calmly, "I had to do something. Money has a way of taking wings with itself, and you know it takes money to keep step with our crowd in Washington. I saw this opening（通道） in the West, and--well, an officer isn't quite as high a position as that of ambassador, but--"
"The ambassador," said the girl, warmly, "doesn't call any more. I needn't ever have done so. You ought to know that. And so now you are one of these brave Western heroes, and you ride and shoot and go into all kinds of dangers. That's different from the Washington life. You have been missed from the old crowd."
The girl's eyes, fascinated, went back, widening a little, to rest upon the glittering handcuffs.
"Don't you worry about them, miss," said the other man. "All officers handcuff themselves to their prisoners to keep them from getting away. Mr. Easton knows his business."
"Will we see you again soon in Washington?" asked the girl.
"Not soon, I think," said Easton. "My butterfly days are over, I fear."
"I love the West," said the girl irrelevantly. Her eyes were shining softly. She looked away out the car window. She began to speak truly and simply without the gloss of style and manner: "Mamma and I spent the summer in Denver. She went home a week ago because father was slightly ill. I could live and be happy in the West. I think the air here agrees with me. Money isn't everything. But people always misunderstand things and remain stupid--"
"Say, officer," shouted the glum-faced man. "This isn't quite fair. I'm needing a drink, and haven't had a smoke all day. Haven't you talked long enough? Take me in the smoker now, won't you? I'm half dead for a pipe."
The bound travelers rose to their feet, Easton with the same slow smile on his face.
"I can't deny a require for tobacco," he said, lightly. "It's the one friend of the unfortunate. Good-bye, Miss Fairchild. Duty calls, you know." He held out his hand for a farewell.
"It's too bad you are not going East," she said, reclothing herself with manner and style. "But you must go on to Leavenworth, I suppose?"
"Yes," said Easton, "I must go on to Leavenworth."
The two men sidled down the aisle into the smoker.
The two passengers in a seat near by had heard most of the conversation. Said one of them: "That officer is a good sort of man. Some of these Western fellows are all right."
"Pretty young to hold an office like that, isn't he?" asked the other.
"Young!" exclaimed the first speaker, "why--Oh! Didn't you catch on? Say--did you ever know an officer to handcuff a prisoner to his right hand?"
