The money went to Warner Music Group, a company that claims to own the copyright on the song. A copyright is the legal right to use or sell a creative product such as a song, a TV show, a book, or a work of art. Warner has claimed the copyright for “Happy Birthday to You” since 1988.“I never thought the song was owned by anyone,” Nelso n said in an e-mail to The New York Times. “I thought it belonged to everyone.”Nelson’s movie is a documenta ry—a film that uses pictures and/or interviews with people to create a factual report of real-life events—and is actually about the history of the “Happy Birthday” song itself.Two sisters named Mildred and Patty Hill wrote a song called “Good Morning to All” in 1893. Over a short period of time, people began to sing the words “happy birthday to you” in place of the original lyrics to the tune of t he Hill sisters’ song.A number of history experts say that there is no record of who actually wrote the “Hap py Birthday to You” lyrics. Historians also say there is no way to know when the general public began singing the “Happy Birthday” song, but they believe it had been sung by the public long before it was printed and owned by a company.Nelson’s lawyers say this piece of music’s history proves that “Happy Birthday to You” belongs to everyone in the general public. That would mean Warner Music Group has no right to charge anyone a fee to sing the song in any setting.Experts estimate that Warner/Chappell, the publishing division of the Warner Music Group, has made about $2 million a year from licensing fees for “Happy Birthday to You.”Nelson’s lawy ers are asking a court in New York City to order Warner/Chappell to return fees they have collected over the p ast four years for use of the “Happy Birthday” song.24.Why did Warner Music Group sue Jennifer Nelson?A.Because she sold “Happy Birthday to You” fo r money.B.Because she secretly used “Happy Birthday to You” song in her film.C.Because she didn’t own the copyright on “Happy Birthday to You” song.D.Because she used the “Happy Birthday to You” song without permission.25.How was the “Happy Birthday” song produced?A.Someone replaced “happy birthday to you” in the song.B.It was written by Mildred as a gift for her sister’s birthday in 1893.C.It was created by someone who used the tune of “Good Morning to All”.D.People were asked to sing the words “happy birthday to you” in the movie.26.The history experts’ statement can prove that the “Happy Birthday” song __________.A.has always been very popularB.was definitely released by the publicC.does not belong to Warner Music GroupD.has more than 32 years’ history s ince 198827.If the court supports the claim from Nelson’s lawyers, __________.A.Warner will return about $8 millionB.she can obtain the copyright on the songC.Warner will have to pay her for her damageD.she can sell the song for about $2 million a yearCWe already know that exercise is good for our bodies. Daily exercise fights the loss of muscle tone and flexibility that tends to increase slowly with age. And it turns out that it has the same fountain-of-youth effects on our brains.Studies show that over time our minds also become less nimble. We lose the ability to process new information or switch between mental tasks quickly—and now we know why.A recent study examined nearly 100 individual studies on exercise and brain function and discovered exer cising an average of 52 hours over six months is “associated with improved cognitive (认知的) performance in older adults with and without cognitive damage.” The type of exercises that are beneficial include aerobic, strength-training and mind-body exercises like yoga or tai chi.In previous studies, researchers from Japan’s University of Tsu kuba wanted to explore this idea by looking at the effect of exercise on the weakening of the brain. They tested the oxygen ability of 60 Japanese men between the ages of 64 and 75 who did not show any signs of dementia (痴呆) orother mental symptoms. Next, they looked at the brain activity of each man as he completed a mental task. They found that the fitter a participant was, the less brain power he used to complete the tasks when compared with his out-of-shape peers, which made him more efficient.Although much research is focused on how exercise may benefit an aging brain, exercise offers brain health benefits at almost any age, and this includes children. A review of 14 studies showed that more physically active schoolchildren do better academically. Exercise actually causes your brain to grow in size. So get moving and keep moving for best results.28.The underlined word “nimble” in Paragraph 2 most probably means __________.A.dull-wittedB. single-mindedC. absent-mindedD. quick-witted29.What can w e infer about the participants’ less-active peers? A.They had significant brainadvantages.B.Their brains were younger than their age.C.Their cognitive performance would decline.D.They had a quick mind when doing the task.30.How does the author support his idea? A.By making comparisons.B.By analyzing study results.C.By describing the processes.D.By telling peers’ experiences.31.What’s the main idea of the text?A.Exercise is beneficial for your bodies.B.Exercise can benefit your brain health.C.Exercise is especially good for dementia.D.Exercise may lower your risk of mental problems.DThe search for beauty spans centuries and continents. Paintings of Egyptians dating back over4,000 years show both men and women painting their nails and wearing makeup. In 18th-century France, wealthy noblemen wore large wigs (假发) of long, white hair to make themselves attractive. Today, people continue to devote a lot of time and money to their appearance.There is at least one good reason for the desire to be attractive: beauty is power. Studies suggest that good-looking people make more money, get called on more often in class, and are regarded as friendlier.But what exactly is beauty? It’s difficult to describe i t clearly, and yet we know it when we see it. And our awareness of it may start at a very early age. In one set of studies, six-month-old babies were shown a series of photographs. The faces on the pictures had been rated for attractiveness by a group of college students. In the studies, the babies spent more time looking at the attractive faces than the unattractive ones.The idea that even babies can judge appearance makes perfect sense to many researchers. In studies by psychologists, men consistently showed a preference for women with larger eyes, fuller lips, and a smaller nose and chin while women prefer men with large shoulders and a narrow waist. According to scientists, the mind unconsciously tells men and women that these traits—the full lips, clear skin, strong shoulders—equal health and genetic well-being.Not everyone thinks the same way. What is considered attractive in one culture might not be in another. Look at most Western fashion magazines: the women on the pages are thin, but is this “perfect” body type for women worldwide? Scientists’ answer is no; what is considered beautiful is subjective and varies around the world. They found native peoples in southeast Peru preferred shapes regarded overweight in Western cultures.For better or worse, beauty plays a role in our lives. But it is extremely difficult to describe exactly what makes one person attractive to another. Although there do seem to be certain physical traits considered universally appealing, it is also true that beauty does not always keep to a single, uniform standard. Beauty really is, as the saying goes, in the eye of the beholder (观看者).32.People’s ideas about beauty __________.A.can be easily describedB.are based upon strict criteriaC.have existed since ancient timesD.have little influence on a person’s success33.In Paragraph 3, the babies in the study __________.A.were rated for their appearanceB.showed a preference for women with larger eyesC.were shown photos of a group of college studentsD.were able to tell attractive faces fromunattractive ones34.We can learn from the passage that __________.A.the ideas of beauty vary as people grow upB.the standards for beauty are based on scientific researchesC.the search for beauty is the power to motivate the beholderD.the understanding of beauty isrooted in cultural backgrounds35.What can probably be the best title for this passage?A.The History of BeautyB.The Mystery of BeautyC.The Standards for BeautyD.The Attitudes toward Beauty第二节（共5 小题；每小题 2 分，满分10 分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。

I was a character-driven writer. How could I mess up the one thing I was supposed to be good at? I was determined to convince my agent that these characters were real. After all, I knew they were real. My main character Lotus had lived inside me for years. I just needed to clarify her on the page.I wrote and edited for a year, trying to respond to this agent’s feedback. But Lotus’ personality began to disappear. I tried to have her make “better” decisions, wear smarter fashion, and have more friends, as my agent said she acted “immature” and was “isolated”. And when this agent ultimately parted ways with me, I felt like I had failed. Now with time and distance, I realize I tried to fit Lotus into a neurotypical style to please my agent. And as a result, Lotus lost her Lotus-ness.When that agent discouraged me from writing Lotus as autistic(自闭的), he said that would make Lotus seem more “vulnerable(脆弱的)” or an “obvious victim”. I didn’t want Lotus to seem vulnerable. Lotus’ autism is what makes her powerful, I tried to explain. But from a neurotypical perspective, Lotus’ autism could only be seen as a weakness.Unsure of how to convince my agent of the strength and power autistic women hold, Ibegan to write Lotus as “neurotypical”. And I failed miserably. After all, what do I know about being neurotypical? My whole life, autism was my default. Not being diagnosed until 2020, I assumed the way I saw the world was “normal”.My current agent encourages me to write from my neurodivergent(神经多样性的) experience. With this invitation, I revisited Lotus and saw her the way I first wrote her. And when I did, the characters and the entire narrative began to make more sense.Identifying my characters as neurodivergent not only gives me joy as a writer, but it has produced my strongest writing. For so long, I’ve combatted the advice to “write what I know”, in part because I didn’t know what I actually knew. I didn’t know I was neurodivergent. But as I mine the specificity of my lived experience, my writing is stronger. There is a power to our lived experience. It’s not a limitation on our craft, but a swinging open of the gates. 4．How did the author feel when receiving the repeated response from the first agent?A．Confused.B．Convinced.C．Determined.D．Disappointed. 5．Lotus’ personality got lost because ______A．Lotus no longer lived inside the author B．the author attempted to please the agent C．the agent failed to sympathize with Lotus D．Lotus was considered childish and lonely 6．What do we know about the author?A．She regretted parting with the agent.B．She owed her success in life to autism.C．She was aware of her autism in the early years.D．She was empowered by her autistic experience.7．What has the author learned from her own experience?A．Stick to your dream despite discouragement.B．Be true to yourself and write from your heart.C．Giving in to authority is the barrier to success.D．Everyone is born an original instead of a copy.At one time, the inheritance of traditional drama was difficult. People of insight screamed “save drama”. Many celebrities and big names put down their figures and went to the community to carry out public welfare performances of opera, and did everything possible to expand the coverage of drama. In recent years, traditional Chinese culture and art has gained a foothold on short video platforms and attracted a large number of young followersthanks to the explosive growth of the short video industry. Relaxing, emotional and fragmented, these video contents perfectly match the demands of the users. With the application of new technologies such as social communication and immersive experiencing, short video platforms are seeing more users, becoming a shining spot of new Internet media.Recently, Huangmei Opera “ Female Consort Prince ” became a hit on short video platforms as a lot of young users covered the aria (咏叹调) in their own way and showed great artistic talents. The interactive platforms are expanding the charm of the traditional opera among young people.Peking Opera was also well-received on short video platforms thanks to a series of augmented reality (AR) effects. Users love to film clips with a set of virtual facial makeup, headwear and costumes. Statistics indicate that these effects were applied by more than 18 million users, most of whom were young people.In addition to Chinese operas, intangible cultural heritage items, such as embroidery, paper-cutting, printing and dyeing, shadow play works, oiled paper umbrella making, and bamboo weaving are also actively promoted on short video platforms. In a word, short video platforms are becoming an important channel to display China’s intangible cultural heritage.Short video platforms, offering a fun, popular and easy way to explore the traditional art forms, are receiving a lot of positive feedbacks from China’s young generations. The seconds, or minutes long videos, along with unlimited possibilities as well as richness of styles, have produced remarkable achievements in promoting traditional Chinese culture.8．What mainly made the inheritance of traditional drama difficult?A．The slow growth of industry.B．The insufficient coverage of drama.C．The poorly-met demands of the users.D．The severe shortage of the drama actors. 9．What led to the promotion of Peking Opera on short video platform?A．The social communication.B．The set of virtual facial makeup.C．The positive feedbacks from users.D．The application of new technologies. 10．Why are paper-cutting and bamboo weaving mentioned?A．To expand the charm of traditional Chinese culture.B．To prove traditional art forms are actively promoted.C．To show the current situation of these cultural heritage.D．To offer new channels to display China’s cultural heritage.11．Which of the following is the best title for the text?A．The Bright Future of Huangmei Opera.B．The Explosive Growth of the Short Video Industry.C．The Simple Way to Explore the Traditional Art Form.D．The Creative Combination of Culture and Technologies.Several years ago, Jeremy Clarkson, presenter of the famous BBC television programme “Top Gear” discovered that one of his guests was half German and half Irish. Immediately, he said: “That's quite a strange combination. It's like, this must be done absolutely perfectly... tomorrow”.This joke played on stereotypes (刻板印象) of the Germans as efficient and the Irish as lazy. Many people could understandably be offended by these kinds of assertions (断言).We do not know every Irish person, so how can we then conclude that every Irish person is lazy?I recently read on a website that Irish business people were described as being 'generally rather casual' and more outwardly friendly than many European counties'. German business people, on the other hand, are considered to be very direct and according to the website, they do not need a personal relationship in order to do business. Once you hear advice like this,it becomes easier to understand where jokes like the one in the first paragraph come from.So why do some people disapprove of the kind of stereotypes as seen in Clarkson's joke, but not baring an eyelid (眨眼) when it comes to generalizations. What is the difference between the two?By definition, a stereotype is a widely held but fixed and oversimplified image or idea of a particular type of person or thing. A cultural characteristic, on the other hand, is a pattern of behaviour that is typical of a certain group.So what does this really mean? Stereotype are simply overstated assumptions about groups of people. Imagine if a tourist visited a small town in Switzerland and saw a number of locals playing the alphorn instrument, and then claimed that Swiss people can play the alphorn. This would be a stereotype! This is an overstated image of the Swiss which is based on one tourist's experience.If however, this tourist were to say that the Swiss are very punctual, this could be seen as a cultural characteristic. This is because it is a pattern of behaviour which is very typical in Switzerland: from their transport system to their business meetings in this way, some people argue that generalizing another culture is not just useful. but important. Politicians alwayshave to be mindful of the cultural characteristics of different countries. By becoming aware of different cultural characteristics,they can avoid causing offence (冒犯) in those cultures.However, others argue that generalizing cultures will always lead to offensive stereotypes. They argue that the best thing we can do is to stop generalizing cultures and start treating people as individuals.All this raises important questions: can making generalizations about groups of people be a positive thing? Or should we always avoid making broad assumptions about different groups?12．When he said, “it's like, this must be done absolutely perfectly... tomorrow”，Jeremy Clarkson really meant________.A．the stereotypes of the Germans and the Irish are not so goodB．the combination of half German and half Irish is interestingC．the characteristics of the Germans and the Irish are oppositeD．the Germans will do it perfectly tomorrow while the Irish won't13．Which of the following is TRUE according to the passage?A．It's typical of the Swiss to be punctual.B．The Swiss can play the alphorn quite well.C．The Irish people are considered as lazy, direct and casual.D．The Germans are thought to be efficient, friendly and direct.14．Politicians think it important to generalize another culture because________.A．they don't want to offend other peopleB．generalizing will lead to offensive stereotypesC．cultural characteristics are better than stereotypesD．they think different cultural characteristics are useful15．The main purpose of this passage is to________.A．illustrate the importance of making generalizationsB．show it is wrong to play jokes on stereotypes of different peopleC．tell us the differences between stereotypes and cultural characteristicsD．discuss whether it is good to make generalizations about groups of people二、七选五“Just think positively!”“It could be worse.”“You should look at the bright side!”We’ve all heard (and maybe used) these phrases without much thought. But they could be contributing to a culture of toxic(有毒的) positivity. For those new to this term, it might sound like an oxymoron(矛盾修辞法). How can positivity be toxic? Isn’t it supposed to be helpful, or “positive”, as the name suggests? 16“Toxic positivity is when somebody avoids all negative thoughts or feelings, pretending everything is going well when it is not,” explains Melissa Dowd, a therapist at PlushCare, a virtual health platform for primary care and mental health services.Whitney Goodman, the author of Toxic Positivity describes toxic positivity as the “endless pressure to be happy and positive, no matter what the circumstances are.” 17 It’s also something we can cause other people to experience.Expressing toxic positivity to others may look like offering them a simple solution to a complicated problem that we know nothing about, or not allowing people around you to appropriately express negative emotions.Toxic positivity causes us to suppress our emotions, which can make them worse.18 “Although it can be helpful to look on the bright side when facing challenges,” Dowd says, “not coping with negative feelings in a healthy way in the moment can lead to those feelings resurfacing later in different areas of your life or as a form of anxiety.” 19 “If I feel like you’re going to dismiss me, I’m going to stop sharing how I’m feeling,” Goodman adds.20 If you’re using toxic positivity against yourself, Goodman suggests remembering it’s OK if you’re upset about something. It’s valid if something annoys you. “Allow ourselves and other people to share when they’re going through a difficult time,” she says. Dowd adds that it’s essential that “we all learn to cope with and process our emotions in a healthy way as opposed to avoiding how we feel” as life’s stressors continue to rise. For example, instead of simply saying “Just think positively,” we’d better say “Sometimes bad things happen. How can I help?”A．Are there ways to avoid toxic positivity?B．Toxic positivity also disrupts connection.C．It can harm people who are going through difficult times.D．This can come up in different situations when we are dealing with pressure.E．They become more intense and can cause long-lasting health concerns in the future.F．Experts say constant forced positivity can lead to the opposite, and have a negative effect.G．This is what we may bring on to ourselves by not allowing negative thoughts and feelings.三、完形填空I am 39 I made it through.

2019-2020学年成都市第七中学高三英语期末考试试卷及答案解析
2019-2020学年成都市第七中学高三英语期末考试试卷及答案解析第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项ALost cities that have been foundThe White CityIn 2015, a team of explorers to Honduras in search of"the Lost City of the Monke God"led to the discovery of the White City. They found the ruins in the Mosquitia region of the Central American country which is known for poisonous snakes, vicious jaguars and deadly insects. It is believed that local people hid here when the Spanish conquerors(征服者) occupied their homeland in the16th century.Canopus and HeracleionModern researchers were teased by the ancient writings about the Egyptian cities Canopus and Heracleion-where Queen Cleopatra often visited. But the cities weren’t found until 1992, when a search in Alexandria waters found that the two cities had been flooded for centuries. Artifacts(史前器物) showedthat the cities once highly developed as a trade network, which helped researchers piece together more about the last queen of Egypt. Machu PicchuA Yale professor discovered "the Lost City in the Clouds"in 1911. A combination of palaces, plazas, temples and homes, Machu Picchu displays the Inca Empire at the height of its rule. The city, which was abandoned in the 16th century for unknown reasons,was hidden by the local people from the Spanish conquerors for centuries keeping it so well preserved.TroyThe ancient city of Troy in homer's The Iliad was considered a fictional setting for his characters to run wild. But in 1871, explorations in northwestern Turkey exposed nine ancient cities layered (层叠) on top of each other, the earliest dating back to about5,000 years before. It was later determined that the sixth or seventh layer contained the lost city of Troy and that it was actually destroyed by an earthquake, not a wooden horse.1.Why did people hide in the White City in the 16th century?A.To survive the warB.To search for a lost city.C.To protect their country.D.To avoid dangerous animals2.Which of the following was related to a royal family member?A.The White CityB.Canopus and HeracleionC.Machu PicchuD.Troy3.What can we learn about Troy?A.It was built by Homer.B.It consisted of nine citiesC.It had a history of 5,000 yearsD.It was ruined by a natural disaster.BByteDance（字节跳动）Group’s TikTok, an overseas version of Chinese short video sharing app Douyin, faces an existential crisis in the United States, as murmurs of a “crackdown”（强制取缔）from the White House forced the Chinese company toengage in talks on selling its US business to Microsoft.TikTok is the fastest-growing registered global mobile internet app, with more than 100 million users, and its rapid growth, especially in the US, is seen as a threat to Facebook. The US government has long viewed globally competitive Chinese high-tech companies including Huawei as a threat and done whatever it could to crack down on（打击）them in the name of “national security”.The US government has not introduced any specific policy against TikTok only threatened it through a number of unclear statements.According to the latest media reports, Microsoft is prepared to press ahead withthe negotiations to take over TikTok’s US operations and complete the negotiations by Sept 15, following talks between Microsoft CEO Satya Nadella and US President Donald Trump.This means that TikTok will have to hand its fate over to some unpredictable power, and even have to sell its assets without the option of setting a price.The US government has failed to find a reasonable legal excuse to deal with TikTok. All private data of TikTok’s US users are stored in the US and are unlikely to be transferred. Considering the US government is trying to deal with TikTok in a political way, TikTok should consider incorporating（合并）the dispute into the US legal process to assert（坚持）its legal rights and interests.TiKTok’s core value lies in its unique algorithms,a product of artificial intelligence that represents the expertise of Chinese engineers and programmers with high-value intellectual property.The US government’s move, which has forced ByteDance to sell TikTok to a US company, is similar to a forced technology transfer and an example of the US’ openseizureof Chinese intellectual property.If ByteDance sells TikTok to a US company for “security reasons", that would set a dangerous precedent, motivating other countries where TikTok operates to follow the US administration's example and cause a chain reaction.ByteDance is a young Chinese private company that cannot deal with a political game played by the US. But as a Chinese company that has gone global, ByteDance has reasons to take up legal means to defend its legal rights. The Chinese government can also consider examining whether the technology transfer in the deal violates China’s law and harms the country’s national interests.4. What is the most valuable as for TikTok?A. Its global popularity.B. Its artificial intelligence.C. Its registered global mobile internet app.D. Its private data of TikTok’s worldwide users.5. Why does the American government force the Chinese company to hand over TikTok’s US operations to a US company?A. Out of so-called political reasons.B. Out of so-called debt reasons.C. Out of so-called technical reasons.D. Out of so-called security reasons.6. What does the underlined word “seizure”probably mean in Para. 8?A. An untrue spoken statement about someone.B. The use of legal authority to take sth from sb.C. The crime of stealing sth from a person or place.D. The act of trying to hurt somebody using physical violence.7. What can be the best title for the news report?A. TikTok must defend its rights legallyB. TikTok is seen as a threat to FacebookC. ByteDance has to sell TikTok to a US companyD. ByteDance agrees to transfer technologyCThe early life of the green sea turtle (海龟) is full of danger. Only one in 1,000 baby sea turtles survive to adulthood (成年). From its home in the sand, it breaks its egg with an egg tooth. Its mother is not there to help it. Instead, it is greeted by crabs, coyotes,and dogs waiting to eat it for dinner. To survive, the baby turtle must hide in the sand until night. Then, it moves slowly to the sea.The small turtle must swim hard to reach the ocean waters. In the sea, it tries hard to find food. It must also keep itself from being food for fish.As dangerous as the sea turtle’s life is in the natural world, its most dangerous enemies are humans. The rubbish left by humans in the ocean causes problems for the small green sea turtle. A little turtle might eat a piece ofplastic (塑料) in the sea. It might also eat oil on the ocean’s surface. Young turtles also get caught in fishing nets. There are laws against hunting sea turtles. Still, many are hunted, both for their meat and for their shells (壳). All of these dangers must be prevented.Sea turtles that do survive to grow into adulthood go through many changes. For example, adult green sea turtles weigh about 500 pounds. They stop eating jellyfish and other meat and eat only plants. And they may plan a trip to go back home again. A mother sea turtle goes back to the beach where she was born. This is the only place where she will lay eggs. Even if it has been forty years since she was a baby, she always knows her way back home.8. Why do baby turtles move to the sea at night?A. They dislike sunshine.B. They prefer lower temperatures.C. They can find food easily then.D. They need to avoid enemies.9. What does the author think of the young turtles in Paragraph 3?A. Pitiful.B. Careless.C. Interesting.D. Courageous.10. What can we learn about sea turtles?A. They mainly feed on fish and meat.B. They always produce eggs at their birthplaces.C. They can live for around forty years.D. They visit their beach homes several times a year.11. What is the text mainly about?A. The homes of green sea turtles.B. How sea turtles find their food.C. The dangers faced by sea turtles.D. How young turtles become adults.DIf you think you’d like to live on Mars, you may have that possibility by 2023. A Dutch company called Mars One will soon advertise for people interested in colonizing (开拓) Mars. Ifyou have all the necessary skills, you could be one of the first colonists. Are you ready for the challenge?You won’t have to pay for the mission to Mars. Mars One has already received money from some donors and is hoping to get more from TV viewers who will become interested in the show where all applicants have a debate for the rare chances.The main responsibility of the first colonists is to create an artificial environment on Mars where there is no air to breathe and no land to farm. Scientists know it’s quite possible because something similar has already been done inAntarctica.Another problem is that space travel to Mars takes nearly a year to get to Mars and the colonists will live the rest of their lives there. When a human lives in an environment without gravity or with low gravity for a long time, the systems in the body weaken. Luckily, spinning (旋转) the spaceship can create artificial gravity, and artificial gravity can ease these problems. It will also be difficult for Mars colonists to be far from home, living in small spaces, and seeing the same people over and over. Colonists with depression could put the mission in danger. Fortunately, a few years ago, a joint Russian and European project called the Mars500 Mission studied people’s reactions in a Mars-like environment. It is viewed as a great success because scientists were able to see how people handle emotional and physical stresses.Recent studies show that seven percent of people would want to go on such an adventure.Mars One will soon start accepting its first colonists. Are you interested?12. What do we know about the applicants to Mars from the first two paragraphs?A. They will land on Mars in 2023.B. They can get money from donors.C. They will compete in a TV show.D. They do not need special skills.13. What will the first colonists do to solve the basic living problems on Mars?A. Create earth-like conditions.B. Build labs inAntarctica.C. Spin the spaceship.D. Start the Mars500Mission.14. What can the life of the first colonists be like according to the passage?A. Difficult and dangerous.B. Different but adaptable.C. Challenging and unbearable .D. Acceptable but depressing.15. What’s the best title for the text?A. Mars: our final destination?B. Ready to be Mars’ colonists?C. Space travel: a thrilling adventure?D. Are you a qualified Mars astronaut?第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。
