阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。续写的词数应为150左右。 The little boy A little boy selling magazines for school walked up to a house that people rarely visited. The house was very old and shabby and the owner hardly ever came out. When he did come out, he would not say hello to his neighbors or passers-by but simply just glare at them. The boy knocked on the door and waited, sweating from fear of the old man. The boy’s parents told him to stay away from the house, and a lot of the other neighborhood children were told the same thing from their parents. Dust found the boy lingering on and hesitating what to do. As he was ready to walk away, the door slowly opened. “What do you want?” the old man said impatiently. The little boy was very afraid but he had a quota(份额) to meet for school with selling the magazines. So he got up the courage and said, “Uh, sir, I am selling these magazines and uh, I was wondering if you would like to buy one from me.” The old man just stared at the boy without a word. The boy could see inside the old man’s house and saw that he had dog figurines(小雕像) on the fireplace mantle. “Do you collect dogs?” The little boy asked. “Yes, I have many collections in my house. They are my family here and they are all I have.” The boy then felt sorry for the man, as it seemed that he was a very lonely soul. “Well, I do have a magazine here for collectors. It is perfect for you. I also have one about dogs since you like dogs so much.” The old man was ready to close the door on the boy and said, “No, boy. I don’t need any magazines of any kind, now goodbye.” The little boy was sad that he was not going to make his quota with the sale. He was also sad for the old man being so alone in the house that he owned. The boy went home and then had an idea. He had a little dog figurine that he got some years ago from an aunt. The figurine did not mean nearly as much to him since he had a real live dog and a large family. Para 1: The little boy headed back down to the old man’s house. ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Para 2: From that day on something changed inside the old man. ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

Few people can refuse a delicious ice cream, especially on a hot day. The only thing that stops the fun is that the treat is hard to enjoy slowly, ending up with a sticky, melted mess. Now, researchers from Colombia’s Pontifical Bolivarian University may have found an unlikely thing to help solve this age-old problem — a kind of fibre from banana plant waste. Bananas, as you probably know, grow in groups on a tree-like plant. Each group is connected to a central rachis (叶轴), which is thrown once the fruit has been gathered. The team, which was led by Dr. Robin Zuluaga Gallego, began by abstracting /drawing out cellulose nanofibrils (CNFs) from the powdered rachis. The tasteless fiber, thousands of times smaller than the width of a human hair, was then added to 100 grams of ice cream mix. With the right amount of CNFs mixed in, the dessert lasted longer in its frozen state than the traditional ice cream, extending the amount of time that the treat can be enjoyed. What was even more exciting was that the fibre increased the stickiness of the low-fat ice cream to levels higher than the full-fat one. Since this is what determines the frozen treat’s creaminess and taste, CNFs could help create the healthier ice cream without influencing the taste of it. The researchers, who presented their findings at the American Chemical Society( ACS) meeting in New Orleans in March, 2018, next plan to study how different types of fat, such as coconut oil, influence the behaviour of CNFs in other frozen treats. The Colombian researchers are not the only ones working on creating a slower-melting ice cream. In 2015, scientists at the University of Dundee in Scotland found that a natural protein called BsIA was very effective in keeping the treat frozen for longer periods of time. With both teams fighting to be the first to get to the market, the future of everyone’s favorite dessert certainly looks bright. 1.What prevents people enjoying an ice cream slowly? A.A kind of fibre from bananas. B.The ice cream’s quick melting. C.The ice cream’s stickiness. D.The fat in the ice cream. 2.Why were CNFs added to ice cream mix? A.To improve its taste. B.To increase its stickiness. C.To reduce its fat content. D.To make it melt more slowly. 3.What does the underlined word “it” in Paragraph 3 refer to? A.The ice cream. B.The fiber. C.The fat. D.The stickiness. 4.What can be inferred from the last paragraph? A.BsIA is popular in the market. B.CNFs are more useful and expensive than BsIA. C.Ice creams with CNFs have been on sale at the market. D.Slowly enjoying an ice cream will soon become a reality.
5G has the potential to disrupt a huge number of industries, including one of the world’s oldest: Farming. Next-generation 5G networks can be 100 times faster than 4G, making communication between devices and servers much quicker. 5G can also carry much more data than other networks. That makes the technology ideal for transmitting information from remote sensors and drones, key tools that are being tested by farmers. 5G is also helping to automate farming processes. UK initiative 5G RuralFirst launched a smartphone app in March called Me+Moo, which lets farmers track a “connected” cow and receive daily updates on the animal’s health and behavior. The system, which is being tested on cows at the Agri-Epi Center in Somerset, England, is funded in part by UK government and supported by the tech company Cisco (CSCO). The cows wear 5G-connected collars that send data to the app on everything from what they’re eating to how they’re sleeping. Farmers can see the information instantly. “This provides peace of mind that the cows are happy, healthy and behaving normally, as well as early warning if they are getting sick, are pregnant or need to be checked,” said project manager Duncan Forbes. Yet to make a difference, 5G will first need to be installed in rural areas. The UN Food and Agriculture Organization (FAO) predicts that in order to provide for the world’s rapidly rising population, the planet will need to grow 70% more food in 2050 than it did in 2009. “To respond to those demands, farmers will need new technologies to produce more from less land, with fewer hands,” reads one report from the organization. In 2017, another 5G RuralFirst project became the first in the world to successfully plant, tend and harvest a crop without a single human stepping foot in the field. Autonomous Automatic tractors sowed the seeds, drones with sensors monitored the crops, and smaller machines took samples from fields to assess what fertilizers and pesticides to apply. 1.Why can 5G help the farming? A.Because it can carry more information. B.Because it can be equipped with sensors. C.Because it can disrupt a lot of industries. D.Because it can be installed in rural areas. 2.What did farmers do firstly if they wanted to use Me+Moo? A.They founded a tech company. B.They let the cows wear 5G-connected collars. C.They kept cows behaving normally. D.They made sure the cows were checked often. 3.According to FAO, how will the world solve the food problem? A.People should control the rising population. B.People should find more and more land. C.People should turn to the new technology. D.People should learn to get more money. 4.How did RuralFirst decide what kind of fertilizer to apply? A.It analyzed the soil. B.It dug earth with tractors. C.It employed experts. D.It hired drones with sensors.
Clara Barton, born on Christmas in 1821, is widely known as one of the most honored women in American history. She began teaching school when most teachers were men at that time. Later, she became one of the first women ever to be employed by the government. Her career in helping the sick began when her brother David became her first patient. He fell down from the roof of a house when Clara was just 11 years old. She stayed by his side and looked after him for three years, learning how to give him all his medicines. When the Civil War began in 1861, she immediately recognized that the poorly equipped soldiers needed help. Instead of waiting for others to step in, Clara collected necessary things on her own, asked the public for donations and learned how to store and distribute them to soldiers. She also read to the soldiers and wrote letters for them. After the Battle of Cedar Mountain in northern Virginia in 1862, Clara arrived at a field hospital at midnight with a vehicle full of supplies. A doctor named Paul Smith at that hospital would later write, “I thought heaven had sent out an angel that night — her assistance arrived at exactly the right time.” In 1869, Clara went to Europe and learned about the International Committee of the Red Cross. Upon her return to the United States, she successfully founded the American Red Cross. She led the organization for the next 23 years. Her last field mission (使命) as president of the American Red Cross was to help the victims of the 1900 Galveston hurricane. She did not retire (退休) from the American Red Cross until she was 83. True to her nature, Clara always went to where the need was the greatest. Today, the American Red Cross continues the mission Clara started more than 100 years ago. With the help of thousands of volunteers, the American Red Cross provides relief to victims of disasters, as well as helps people prevent, prepare for and respond to all sorts of emergencies. 1.We can learn from Paragraph 2 that Clara Barton was . A.honest B.caring C.talented D.modest 2.After the Civil War broke out, Clara Barton . A.joined the army and fought bravely B.went to Europe for further study C.continued to work as a teacher D.did a lot to help soldiers 3.Seeing Clara Barton’s arrival, Dr. Smith must have felt .

As people try to keep social engagement during self-isolation, citizen science offers a unique opportunity. Defined as "public participation and collaboration in scientific research", citizen science allows people to use technology to unite towards a common goal —from the comfort of their homes. And it is now offering a chance to contribute to research on the coronavirus pandemic. With so many of us staying home, this could help build a sense of community where we may otherwise feel helpless, or struggle with isolation. Anyone is welcome to contribute. You don't need expertise, just time and interest. Projects exist in many forms, catering to people of diverse ages, backgrounds and circumstances. Many projects offer resources and guides to help you get started, and opportunities to collaborate via online discussion forums. Scientists worldwide are racing to find effective treatments and vaccines to halt the coronavirus pandemic. As a citizen scientist, you can join the effort to help tackle COVID-19, and other infectious diseases. Foldit is an online game that challenges players to fold proteins to better understand their structure and function. The Foldit team is now challenging citizen scientists to design antiviral proteins that can bind with the coronavirus. The highest scoring designs will be manufactured and tested in real life. In this way, Foldit offers a creative outlet that could eventually contribute to a future vaccine for the virus. Another similar project is Folding@home. This is a distributed computing project that, rather than using you to find proteins, uses your computer's processing power to run calculations in the background. Your computer becomes one of thousands running calculations, all working together. 1.Where does a citizen scientist work? A.In the office. B.At research center. C.In the factory. D.At home. 2.Who can be a citizen scientist? A.Anyone who has time and interest. B.The expert who is interested. C.People who are well educated. D.Doctors who are experienced. 3.How can a citizen scientist join in the effort to help deal with the COVID-19 and infectious diseases? A.He can play Foldit an online game and get the highest scores. B.He can do experiments about COVID-19. C.He can design a new game about COVID-19. D.He can help build a sense of community. 4.What is true about Folding@home? A.It is the same project as Foldit. B.It is a computer project using you to run calculations by computer. C.It is a project using you to find proteins. D.It is done by experts.
Music has a great effect on everyone. But does music affect plants, too? People have been experimenting with music for almost three decades. From school-level projects to higher-level scientific experiments, the effect of music on plants has been a confusing and debatable topic. We know music is sound and sound is nothing more than a wave. Plant growth is a result of the cell division that takes place within the cells. But why is music associated with plant growth? In humans, music has a strong effect on our health and mood, and over the years, people have claimed that the same effect has been observed on plants, too. Plants are sensitive by nature, and many people claim that they have feelings just as humans do. There are stories about plants shedding tears. Although scientists do not support these as facts, these myths have led them to take up various experiments on plants. Various studies have proved that plants respond to acoustic (音响的) energy. It increases their rate of growth and their size, and influences their overall health. Dan Carlson, after a thorough study over a span of many years, has reached a conclusion that music helps plants absorb nutrients(养分) more efficiently. It took Dan about fifteen years to develop a foliage spray (叶面喷剂) that is used beneficially with the sound frequencies. Carlson calls this spray “Sonic Bloom”. His findings have proved to be beneficial for countless farmers and have resulted in－according to Guinness Book of World Records－the largest indoor plant on record. The Purple Passion was treated with the Sonic Bloom process. It grew to be 1,300 feet tall and was alive even after 25 years. Its normal lifespan(寿命), however, is 18 months and it grows not more than 18 feet tall. The book, Secret of the Soil, writes about Sonic Bloom and its results. Sonic Bloom is also sold in the market. 1.What inspired scientists to experiment with plants? A.The effects of music on humans. B.Plants are sensitive by nature. C.The cell division taking place within the cells. D.People’s debatable opinion of the effect music has on plants. 2.What is the main idea of Para. 3? A.Nutrients are important to plants. B.Music can have some good effects on plants. C.How the rate of growth of plants can be improved. D.What kinds of music can contribute to the growth of plants. 3.What did Dan Carlson develop? A.A spray called “Sonic Bloom”. B.A method to grow larger plants. C.A special plant that grows very fast. D.Acoustic energy that plants respond to 4.Why is the Purple Passion included in Guinness Book of World Records? A.It is the oldest indoor plant. B.It is the largest indoor plant. C.It gives off the most pleasant smell. D.It can grow in the toughest conditions.
Nurses play a vital role on the front lines of the novel coronavirus(冠状病毒）pandemic. But a shortage of these essential health care workers could pose challenges in countries dealing with a growing number of COVID-19 cases. "One of the lessons I hope the world learns from COVID-19 is that we must invest in nurses ," said World Health Organization Director-General Tedros Adhanom Ghebreyesus during a speech Tuesday in celebration of World Health Day. WHO's new "State of the World's Nursing 2020" report has identified a global shortage of 5.9 million nurses. Many of those gaps are found in Africa, Southeast Asia, the Eastern Mediterranean, and parts of Latin America. Among regions of the world, the Americas have the highest density of nurses at 83.4 per 10,000 people, followed by Europe with 79.3 nurses per 10,000 people. In contrast, there are 8.7 nurses per 10,000 people in Africa, 15.6 nurses per 10,000 people in the Eastern Mediterranean region, 16.5 nurses per 10,000 people in Southeast Asia, and 36 nurses per 10,000 people in the Western Pacific. But there are also differences within regions. In the Americas, for example, countries such as Brazil, Canada, Chile, and the US have a higher density of nurses at close to or over 100 per 10,000 people, distorting the regional average. Many of the neighboring countries in the region have less than 50 nurses per 10,000 people. In Haiti, there are only 3.8 nurses per 10,000 people. When based on country income, data in the report shows an unsurprising trend: The higher the income, the higher the nursing density. In low-income countries, the average density of nurses is 9.1 per 10,000 people, while the figure for high-income countries is 107.7 per 10,000 people. But training more nurses won't solve the problem, said Dr. Giorgio Cometto, WHO coordinator on human resources for health policies and standards. "If the country lacks the economic capacity to employ them or to create economic opportunities for them to work as nurses ... training more nurses can just go into the direction of making labor market imbalances, resulting in unemployment among nurses. And that's a huge wastage of human capital as well as financial resources," Cometto said. The key is balancing training with the creation of employment opportunities in rural areas where there are known health worker shortages. That may be easier said than done, especially among countries that are suffering from chronic or complex emergencies, in active conflict, or struggling in the wake of conflict. But in these settings, the international aid community can arrange its assistance with national priorities and covering recurrent costs, such as salaries, within a specified period of time, Cometto said. 1.How many nurses are needed according to WHO's new" State of the World 's Nursing 2020" report? A.6 million. B.8.7Million. C.3.8 Million. D.5.9Million. 2.From the figures in the passage , where are nurses most needed? A.Africa. B.Haiti. C.Eastern Mediterranean region. D.Southeast Asia. 3.Based on the country income what does the data in the report show? A.The higher the income ,the more nurses are. B.The higher the income,the more doctors are. C.The lower the income ,the more doctors are. D.The lower the income, the more nurses are. 4.From what Cometto said, we know that___. A.It is easy to solve the problem of shortage of nurses. B.It is not easy to solve the problem of shortage of nurses. C.Training more nurses is a way to solve the problem. D.The international aid community can arrange its assistance all the time.

Hearing that you have a plan to learn Chinese, I’m writing to recommend a university that you can have a fruitful learning experience. My recommendation is Peking University, a well-known university suitable for language learning in China. The reasons account for my recommendation are as follows. To begin with, being a first-class university with the best equipments and the finest teachers, Peking University is capable of offering professional guide and systematic training to you to master Chinese. That I think will impress you must be the resources you can have access during the whole process. Furthermore, locating in Beijing, which is the capital of China, this university has had profound historical culture. Thus, not only can we get to know those who speak standard Mandarin, but you will experience the power of Chinese culture. All in all, I really hope you can pay a visit to Beijing. I’ll wait for you here and offer help wherever you need. Yours sincerely, Jane

How to help each client is different to everyone, and it is a very individualized process.4. Because of this, a life coach must develop plans based on each client’s strengths, weaknesses, abilities and so on. A life coach will also usually take each client’s morals and values into consideration. Some life coaches may be able to find employment with a few select universities and corporations. There are also a handful of large life coaching firms that hire life coaches as well. The majority of life coaches, however, work for themselves, opening their own life coaching practices. 5. A.Methods that work for one client may not work for another. B.A good life coach should try to satisfy all the needs of his clients.

Smile! It makes everyone in the room feel better because they, consciously or unconsciously, are smiling with you. Growing evidence shows that an instinct for facial mimicry(模仿) allows us to empathize with and even experience other people’s feelings. If we can’t mirror another person’s face, it limits our ability to read and properly react to their expressions. A review of this emotional mirroring appears on February 11 in Trends in Cognitive Sciences. In their paper, Paula Niedenthal and Adrienne Wood, social psychologists at the University of Wisconsin, describe how people in social situations copy others’ facial expressions to create emotional responses in themselves. For example, if you’re with a friend who looks sad, you might “try on” that sad face yourself without realizing you’re doing so. In “trying on” your friend’s expression, it helps you to recognize what they’re feeling by associating it with times in the past when you made that expression. Humans get this emotional meaning from facial expressions in a matter of only a few hundred milliseconds. “You reflect on your emotional feelings and then you generate some sort of recognition judgment, and the most important thing that results in is that you take the appropriate action—you approach the person or you avoid the person,” Niedenthal says. “Your own emotional reaction to the face changes your perception of how you see the face in such a way that provides you with more information about what it means.” A person’s ability to recognize and “share” others’ emotions can be prevented when they can’t mimic faces. This is a common complaint for people with motor diseases, like facial paralysis(瘫痪) from a stroke, or even due to nerve damage from plastic surgery. Niedenthal notes that the same would not be true for people who suffer from paralysis from birth, because if you’ve never had the ability to mimic facial expressions, you will have developed compensatory ways of interpreting emotions. People with social disorders associated with mimicry or emotion-recognition damage, like autism(自闭症), can experience similar challenges. “There are some symptoms in autism where lack of facial mimicry may in part be due to limitation of eye contact,” Niedenthal says. Niedenthal next wants to explore what part in the brain is functioning to help with facial expression recognition. A better understanding of that part, she says, will give us a better idea of how to treat related disorders. 1.According to the passage, facial mimicry helps ________. A.experience one’s own feelings clearly B.change others’ emotions quickly C.respond to others’ expressions properly D.develop friendship with others easily 2.We can know from Paragraph 4 and 5 that ________. A.people with motor diseases may also suffer from autism B.people born with facial paralysis may still recognize emotions C.people with social disorders can’t have eye contact with others D.people receiving plastic surgery have difficulty in mimicking faces 3.According to Niedenthal, the next step of the study will focus on ________. A.how we can treat brain disorders B.what can be done to regain facial mimicry C.how our brain helps us with emotional mirroring D.what part of our brain helps recognize facial expression 4.The passage is written to ________. A.discuss how people react positively to others’ smiles B.draw people’s attention to those with social disorders C.introduce a new trend in facial expression recognition D.explain how emotional mirroring affects people’s empathy
They asked Katherine Johnson for the moon, and she gave it to them. With little more than a pencil, a slide rule and one of the finest mathematical minds in the country, Mrs. Johnson, who died at 101 on Monday, calculated the precise track that would let Apollo 11 land on the moon in 1969 and, after Neil Armstrong’s history—making moonwalk, let it return to Earth.
Yet throughout Mrs. Johnson’s 33 years in NASA and for decades afterwards, almost no one knew her name. Mrs. Johnson was one of several hundred strictly educated, supremely capable yet largely unrecognized women who, well before the modern feminist movement, worked as NASA mathematicians. But it was not only her sex that kept her long unsung. For some years at midcentury, the black women were subjected to a double segregation (隔离)：They were kept separate from the much large group of white women who in turn were segregated from the agency’s male mathematicians and engineers. Mrs. Johnson broke barriers at NASA. In old age, Mrs. Johnson became the most celebrated of black women who served as mathematicians for the space agency. Their story was told in the 2016 Hollywood film Hidden Figures, which was nominated for three Oscars, including best picture. In 2017, NASA dedicated a building in her honor. That year, The Washington Post described her as “the most high- profile of the computers”—“computers” being the term originally used to describe Mrs. Johnson and her colleagues, much as “typewriters” were used in the 19th century to represent professional typists. She “helped our nation enlarge the frontiers of space,” NASA’s administrator, Jim Bridenstine, said in a statement on Monday, “even as she made huge steps that also opened doors for women and people of color in the universal human quest to explore space.” As Mrs. Johnson herself was fond of saying, her term at Langley—from 1953 until her retirement in 1986—was “a time when computers wore skirts.” 1.What is the function of the first paragraph? A.To present the Apollo moon mission. B.To stress Mrs. Johnson’s contributions C.To honour Neil Armstrong’s moonwalk. D.To mourn a great woman—Mrs. Johnson. 2.Which of the following was the toughest thing Mrs. Johnson had to overcome? A.The difference between male and females in this field. B.People’s not recognizing her talent. C.Inequality in gender and race. D.The hardships before the modern feminist movement. 3.Why were Mrs. Johnson and her colleagues described as “computers”? A.Because they used computers to keep their work secret. B.Because they were the agency’s human calculators. C.Because computer systems engaged them deeply. D.Because they calculate precisely using computers. 4.What can we learn from Mrs. Johnson’s experience? A.Don’t judge a person by his appearance. B.The world awaits our discovery. C.Use knowledge to wipe out ignorance. D.Never be limited by the labels attached by others.
