阅读下面短文，根据所给情节，使之构成一个完整的故事。
Mr. Ellet gave George a bright silver dollar for a New-year gift . Little George thought of all the fine things he might buy with it. The ground was all covered with snow; but the sun shone out bright, and everything looked beautiful. So he put on his hat , and ran out of home. As he went skipping along, he met some boys throwing snowballs. George soon engaged in the sport, He sent a ball at James Mason, but it missed him, and broke a window on the other side of the street. George feared someone would come out of the house and find him. So he ran off as fast as he could. As soon as he got round the next corner, George stopped, because be was very sorry for what he had done. He said to himself, “I have no right to spend my silver dollar, now. I ought to go back, and pay for the glass I broke with my snowball. I will go and pay for it. If it takes all my money, I will try not to be sorry. I do not think the man will hurt me if I pay for the what I have done.”
He went up and down the street, and felt very sad. He wished very much to buy something nice. He also wished to pay for the broken glass. At last he said, “It was wrong to break the window, though I did not mean to do it. It is only fair to pay the gentleman for his loss” George started off, and felt much happier for having made up his mind to do what was right. He rang the doorbell. When a gentleman came out, George said, “Sir, I threw a snowball through your window. But I did not intend to do it. I am very sorry, and wish to pay you. Here is the dollar my father gave me as a New Year gift.” The gentleman took the dollar, and asked George if he had no more money. George said he had not.

When Chinese researchers successfully figured out the genetic structure of the novel coronavirus in January, many people thought a vaccine(疫苗) would soon follow. 1.
First, scientists must work together to understand the structure of the virus and develop potential vaccines to fight against it. 2. After passing animal tasting, clinical trials of the vaccine are then done on humans. Finally the vaccine needs to be approved by officials before it can be made available to the public. All of the steps are necessary to make sure that the new vaccine is safe for people to use. 3. With technological advancements and government funding (资金), the time it takes to develop vaccines can be reduce.
CEPI, an international organization that develops vaccine, for example, is funding programs that focus on making a vaccine for the novel coronavirus. About 35 companies and academic institutions, including the US company Moderna, funded by CEPI, are searching for a COVID-19 vaccine. 4. Once a vaccine is ready, 100 million doses (剂量) could be made within a year, according to Modena’s CEO Stephane Bancel.
5. Not only do they help to save individual lives, but they also help the local and even the global community.
A.This is why a vaccine is developed.
B.But that’s a lot easier said than done.
C.However, experts say vaccines are unlikely to be available
D.Once these first vaccines are made, they are tested on animals.
E.Sometimes, this process can take as long as 10 to 15 years to complete.
F.Even though vaccines take a long time to develop, they are very important.
G.A few have begun testing in animals, while Moderna’s attempt has started human trials.
Implanted (植入的) devices, such as heart pacemakers, are a valuable part of modern medicine. Their use, however, is limited by the need to renew their batteries and this is a particular problem for those inside the wearer’s head. Therefore, a way to power such implants without replacing their batteries at all would thus be welcome. And Dr Hyuck Choo and his colleagues think they have one. They plan to collect the necessary energy from the vibrations(震动) that occur when someone is talking.
DrChoo’s power plants are small sheets of lead zirconate titanate, a material that produces electricity when it vibrates. He knew that sheets of the size he chose have a resonance (共振) at around 690Hz. This is well above the normal range of the human voice. Using larger sheets would lower the resonance frequency. So he sought to lower a sheet's resonance frequency without increasing its area by caring a special shape out of it. And it worked!
When Dr Choo and his colleagues tested the carved sheets by exposing them to a range of frequencies and monitoring the amount of electricity generated, they found that the voltage was between 100Hz and 120Hz (approximately the common frequencies of adult male vices), and also between 200Hz and 250Hz (the female voice s common frequencies). And, although the amount of power produced is not huge, it seems adequate for the task.
As Dr Choo reported at a conference on January 26, he and his team were able to harvest a tenth of a mill watt per square centimetre of lead zirconate titanate from the voice of a man talking at 70 decibels (分贝), which is normal speaking volume, and tents from someone shouting at 100 decibels Implants usually require a tenth of a mill watt or less to function so this suggests a practical device might be within reach-especially as the vibrations produced by the voice travel efficiently up through the skull, meaning the generator could be put into an implant.
1.What limits the use of implanted devices?
A.The shape of the devices. B.The effect of the vibrations.
C.The need for continuous power. D.The difficulty in producing the battery
2.What problem did Dr Choo have to solve in Paragraph 2?
A.To renew the batteries of the implants.
B.To make the resonance above the human voice.
C.To pick out suitable material for his power plants.
D.To ensure the resonance of the sheets fit in with the human voice.
3.What does “the task” in Paragraph 3 refer to?
A.Exposing the sheet to sounds. B.Powering the implanted devices.
C.Lowering a sheet's resonance frequency. D.Monitoring the electricity produced.
4.What can we learn from the last paragraph?
A.The voice powered device is likely to be available.
B.A man has to shout loudly when using the device.
C.The device will be put into production after the conference.
D.The generator should be put into the skull when used.
Robert has never had an art lesson or even visited a museum in fact. he has spent a good part of his life mopping floors. But when he began painting on canvas (帆布) at age 60—after years of sketching (素描) people on the subway -he knew he had found his passion. “I was very lonely” he said, “It made me feel good to create something beautiful.”
Now, Robert, 75, is debuting (首秀) his collection of colorful scenes and landscape at New York City’s Outsider Art Fair, the premier showcase for self-taught artist. “It feels great to say I am an artist. I was always told that I didn’t have any talent. I became something from nothing.” adds Robert.
Abandoned by his parents to an orphanage at age 7, Robert was on his own by the time he was 15, working the counter at a Schrafft’s restaurant in Manhattan and street-bustling for money on the side. At Scharafft’s, one of his regular customers was a former school teacher Marian O’Conner, who taught him to read and later left him enough money to buy a modest apartment. “She told me someday I would be something,” said Robert, who considered O’Conner his second mother. “So I kept going.” In 2009 artist Daniel Belardineli discovered Robert’s work on the walls of the town hall and arranged his first art show. “It was like a left blow,” he said, “I saw these raw drawings that jumped out with emotion.” Whatever comes next, for Robert it has all been worth it. “I have had a lot of hard times,” said Robert, “But my art kept me going. Good thing happen to those who wait.”
1.Why did Robert begin painting on canvas?
A.He was inspired by an art museum.
B.He was told that he was talented in painting.
C.He felt passionate about painting beauty in life.
D.He was invited to the New York City’s Outsider Art Fair.
2.What does the underlined sentence in Paragraph 2 mean?
A.He lived up to the expectation. B.He knew nothing about painting.
C.He rose to fame from an unknown. D.He had no trouble becoming famous.
3.According to Daniel Belardineli, Robert’s painting is probably____.
A.subtle and life-like B.dull but meaningful
C.healing and peaceful D.primitive but powerful
4.What would be the best title for the text?
A.A natural born artist B.A lonely orphan
C.A caring teacher D.A lucky dog
