Grandparents Peter and Chris stepped on the long journey after deciding to “do something a bit different”. They traversed (横穿) cities, deserts, mountains and everything in between across Europe, the Middle East and the East Asia. The married couple of 37 years enjoyed themselves with delicious local food and spent most nights inside a tiny tent put up wherever they could find shelter.Peter, 66, said the moment they finally had a look at the famous Great Wall after a year and a half of cycling 30 miles a day was “really exciting”. At the end of their journey, the special pair didn’t fly home but instead choose to book a cabin (舱) inside a 400m-long container ship. The final part was a three-week voyage from Singapore across the Indian Ocean and into the Mediterranean Sea before arriving at Southampton.“You never know what the day is going to bring. All you know is that you aregoing to get on your bike and cycle. Every day is an adventure and every day is new. Overall, the experience is absolutely unbelievable, ” Peter said.Peter and Chris initially set out to cycle from Britain in January 2017 but were forced home. They had cycled all the way to Hungary when Peter slipped on tiles and broke his leg. After seven months of recovery, the couple set out again in Britain. They finally arrived in China in November 2018.Both Peter and Chris agreed that the best part of the entiretrip was coming across the kindness of strangers along the way, many of whom invited the couple for food and drink.

Fine particle pollution declined rapidly following the new rules on industrial emissions and the promotion of cleanfuels, according to the study, published on Monday in the National Academy of Sciences of the United States of America. The study, which focused on the period from 2013-2017, was conducted by a group of Chinese researchers and scientists.PM2.5, as this kind of pollution is known, is so small that it can enter the bloodstream, potentially leading to cancer, stroke and heart attack in the long term. After rapid industrialization and weak regulations left the country with a reputation for smog and bad air quality, Chinese authorities started to take air pollution seriously in 2008.In 2013, Beijing had PM2.5 concentrations 40 times higher than levels recommended by the World Health Organization (WHO), and the governmentintroduced its toughest-ever clean air policies that year. The study found “signif icant declines” in PM2.5 levels across China from 2013-2017, with new standards for thermal power plants and industrial boilers, the replacement of old factories, and new emissions rules for vehicles. The authors say this “confirms the effectiveness of Chi na’s recent clean air actions.”These recent actions have seen Beijing fall out of the top 100 most-polluted cities in Asia in recent years, with the pollution levels 10% lower across Chinese cities between 2017 and 2018, according to a report by Greenpeace and AirVisual. Shanghai, the country’s largest city and financial capital, has also made environmental advances, such as adopting strict recycling regulations. Public pressure has been the driving force of pollution policy in China.Air pollution is a global issue, and India is now home to 22 of the 30 most polluted world cities, according to the Greenpeace and AirVisual report. In the US, a recent study said air pollutionwas linked to more than 107,000 deaths in 2011 and cost the country $866 billion.8. What saved many lives in China?A. China’s clean air policies.B. The increased particle pollution.C. The study by researchers.D. The reduction of the clean fuels.9. Why did PM2.5 cause many diseases?A. It was called smog.B. It made the air cleaner.C. It went into the blood.D. It had a bad reputation.10. When did Chinese government decide to treat the pollution?A. In 2008.B. In 2013.C. In 2017.D. In 2018.11. What did people in Shanghai do to protect the environment?A. They built the thermal power plants.B. They stopped using industrial boilers.C. They made Shanghai financial capital.D. They tried to recycle some rubbish.DIn the 1994 film Forrest Gump, there’s a famous saying, “Life is like a box of chocolates; you never know what you’re gonna get.” The surprise is part of the fun. Now blind box toys are bringing the magic of surprise to online shopping.A blind box toy is hidden inside uniform packaging(包装) butinvisible from the outside. You don’t know what will be inside, although the toys typically come from pop culture, ranging from movies to comics and cartoons.Blind boxes have caught on since they were first introduced from Japan to China in 2014. According to a 2019 Tmall report, the mini-series of Labubu blind box. designed by Hong Kong -born Kasing Lung, was named Champion of Unit Sales with 55,000 sold in just 9 seconds during the Singles Day shopping event. Most customers for blind boxes are young people aged 18 to 35.According to The Paper, blind box toys are popular in part because of their cute appearances. The typically cute cartoon figurines (小塑像) come in miniature (微型的) sizes, making them suitable for display almost anywhere.Even if blind boxes are not their top choice for decorations(装饰品), the mystery and uncertainty of the process also attracts people. It’s the main reason why people buy blind boxes one after another.“Fear of the unknown is always a part of the box-opening process,” said Miss Cao, 24, who lives and works in Shenyang. Speaking to Sina News, she said: “Until you open all the boxes, you cannot know what it is inside.”Opening a blind box is a delightful little surprise for our mundane daily lives, something small but fun to wait for each day, week or month. When people open this simple little box, they may be disappointed, but the uncertainty is part of the fun. People will open more blind boxes and hope for a better outcome.When someone re-makes Forrest Gump, don't be surprised if he says, “Life is like a blind box.”12.What feature of blind boxes attracts people?A.They often get toys designed by famous artists.B.They don’t know what they’ve got until they open them.C.They can learn about pop culture from the packaging.D.They can experience the excitement of online shopping.13.Why does Miss Cao love blind box toys?。

Luckily, in the age of social media, we are never truly alone. And with the extra time spent indoors, artists are stepping up to help us all with the following clubs.Drawing from Distance by Sarah Beth MorganLet’s shine some light during this trying time and encourage social distancing! I’m starting this tomorrow myself — but from what I offer, take whatever you please. No rules! Just have fun!Stayathome Art Club byCarsonEllisHello! I’ll be posting art homework here every weekday morning when I can. They’ll be designed for kids and grownups alike. Here is your first homework: Draw a picture of yourself from the shoulders up. You can follow some useful examples. If you want to share or see other people’s self-picture, use these hashtags: #Stayathomeartclub# QACselfportrait30-Day indoor Art by Danielle KrysaOne month of avoiding crowds? I’m in! I challenge you to use this time inside to make one piece every day from now until mid April. Please join me in playing around with some painting ideas that have been rolling around in my head but haven’t found their way onto paper yet.

I use it asa coaster and to level unsteady table legs. It makes an excellent cat toy.Welcome to the pandemic (疫情) of disappointments. Canceled trips or ones never planned in case they would be canceled. Family reunions, study-abroad years, lazy beach vacations. Poof. Gone. Ruined by a tiny virus, the list of countries where our passports are not welcome is long.It is not natural for us to be this sedentary (定居的). Travel is in our genes. For most of the time our species has existed, we've lived as nomadic (游牧的) hunter-gatherers. But what if we can't move? What's a traveler to do? There are ways to answer that question. "Despair," though, is not one of them.We are an adaptive species. We can tolerate brief periods of forced sedentariness. We pass the days glancing through old travel journals and Instagram posts. We gaze at souvenirs. All this helps. For a while. Then, what hope do we have?I think hope lies in the very nature of travel. Travel involves wishful thinking. It demands a leap of faith, and of imagination, to board a plane for some faraway, land. Travel is one of the few activities we engage in not knowing the outcome and are drunk in that uncertainty. Nothing is more forgettable than the trip that goes exactly as planned.That's one reason why I have faith in travel's future. In fact, I'd argue travel is an essential activity. It's not essential the way hospitals and grocery stores are essential. Travel is essential the way books and hugs are essential. Food for the soul. Right now, we're between courses, enjoying where we've been, expecting where we'll go. Maybe it'sZanzibarand maybe it's the campground down the road that you've always wanted to visit.4. From the first paragraph we learn that the author is _______ .A. desperateB. humorousC. boredD. worried5. From the author's perspective, what's the point of travel?A. To feel hopeful.B. To make a wish.C. To take adventures.D. To broaden horizons.6. How is the passage mainly developed?A. By showing evidences.B. By providing examples.C. By making comparisons.D. By interpreting opinions.7. What does the passage mainly talk about?A. Where to go for a trip.B. Why people need to travel.C. How to fight the pandemic.D. What people should do at home.CPopularization has in some cases changed the original meaning of emotional (情感的) intelligence. Many people now misunderstand emotional intelligence as almost everything desirable in a person's makeup that cannotbe measured by an IQ test, such as character, motivation, confidence, mental stability, optimism and “people skills.” Research has shown that emotional skills may contribute to some of these qualities, but most of them move far beyond skill-based emotional intelligence.We prefer to describe emotional intelligence as a specific set of skills that can be used for either good or bad purposes. The ability to accurately understand how others are feeling may be used by a doctor to find how best to help her patients, while a cheater might use it to control potential victims. Being emotionally intelligent does not necessarily make one a moral person.Although popular beliefs regarding emotional intelligence run far ahead of what research can reasonably support, the overall effects of the publicity have been more beneficial than harmful. The most positive aspect of this popularization is a new and much needed emphasis (重视) on emotion by employers, educators and others interested in promoting social well-being. The popularization of emotional intelligence has helped both the public and researchers re-evaluate the functionality of emotions and how they serve people adaptively in everyday life.Although the continuing popular appeal of emotional intelligence is desirable, we hope that such attention will excite a greater interest in the scientific and scholarly study of emotion. It is our hope that in coming decades, advances in science will offer new perspectives (视角) from which to study how people manage their lives.Emotional intelligence, with its focus on both head and heart, may serve to point us in the right direction.8. What is a common misunderstanding of emotional intelligence?A. It can be measured by anIQ test.B. It helps to exercise a person’s mind.C. It includes a set of emotional skills.D. It refers to a person’s positive qualities.9. Why does the author mention “doctor” and “cheater” in paragraph 2?A. To explain a rule.B. To clarify a concept.C. To present a fact.D. To make a prediction.10. What is the author’s attitude to the popularization of emotional intelligence?A. Favorable.B. Intolerant.C. Doubtful.D. Unclear.11. What does the last paragraph mainly talk about concerning emotional intelligence?A. Its appeal to the public.B. Expectations for future studies.C. Its practical application.D. Scientists with new perspectives.DOver the years, NASA has successfully sent several rovers (飞行器) to Mars. While the science laboratories continue to provide important information on the Red Planet, they keep the space exploration rovers staying closeto the original landing place.To get a more comprehensive (详尽的) view of Mars, the US Space Agency plans to make a small test helicopter with the Mars 2020 Rover, which will be sent off in July 2020.The football-sized “marscopter” weighs about four pounds.It can fly at about ten times the speed of helicopters on Earth. The light weight and fast speed are important for the helicopter to be able to fly in the thin Mars atmosphere, which is about just one percent of that of Earth. “To make it fly in that thin Mars atmosphere, we had to make everything ready, and make it as light as possible while being as strong and powerful as it can possibly be. “Mimi Aung, Mars helicopter project manager, said in a meeting.Upon landing on the Red Planet, the Mars 2020 Rover will find a proper location to send of the helicopter. The helicopter will start with a short climb, no higher than 10 feet, and hover (盘旋) for just 30 seconds before landing back on the Mars surface. If all goes well, five more flights of longer distances, for 90 seconds each, will be conducted over the next 30 days. The short journeys will be recorded by a small camera and sent back to the scientists on Earth.If the plan goes on well, the first helicopter to fly in another world, will open up a whole new way to explore Mars. The Mars helicopter's first flight will be a great invention. For those of us whose research is about flight, thatwould be a wonderful, historic moment.12. To fly in thin Mars atmosphere，we should make the helicopter_______.A. strong and heavyB. heavy and fastC. light and fastD. strong and slow13. How many times will the helicopter fly?A. Three timesB. Four timesC. Five timesD. Six times14. What can we learn from the last paragraph?A. It’s interesting to fly in another world.B. I' s important to fly in another world.C. The plan to fly the helicopter goes on well.D. The helicopters first flight is successful.15. What may be the best title for the passage?A. To send a helicopter to Mars in 2020B. To send a rover to Mars in 2020C. To live in the thin Mars atmosphereD. To send back records to scientists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。

We learned that，over time，a full life can leave little time for personal rest and for reflection，hanging out with friends，or just being“off. ”So，after a number of years，we make a change. If I can persuade you to take your own PTO，then these might help.■Schedule itFirst of all，one of our favorite family sayings is“schedule it. ”Sounds easy enough，but life gets complicated managing full-time work and full-time family. Put yourPTO time on the calendar and you make it a real thing.■Be flexible and strictIf you can schedule PTO at the same time each week，then all the better. Because our calendar can get rather full，flexibility in scheduling becomes a necessity. But being strict in actually taking the time each week is more important. Skipping it once makes it easier to skip again.■Take enough timeMy typical PTO lasts a couple of hours or longer. Sometimes it might be half the day depending on what I’m doing. The goal is to spend enough time away to1et your shoulders drop.■Do what you want to doRemember，PTO time is about personal time to do what you want to do，not what you have to do. PTO time is about relaxation. Grab a friend and get a beer. Work can wait until tomorrow.1.What can be the first step to take the PTO?A.Persuade the family.B.Have a personal rest.C.Ask friends for advice.D.Make a time plan.2.What does the underlined part“let your shoulders drop”probably mean?A.Get you more focused.B.Have you feel relaxed.C.Shake your shoulders often.D.Make you feel more stressed.3.What does the text mainly talk about?A.Tips on how to take your time offB.Skills to manage work and familyC.Advice on how to free yourselfD.Ways of scheduling your workBScientists have recently discovered thatAndean condors (秀鹫)— some of the world’s largest birds——barely flap their wings at all while flying. Instead, they use rising air currents to remain in the air for hours.The Andean condor is the world’s largest soaring bird. They can weigh up to 15 kilograms. Their wings, when spread out, measure up to three meters. Their main food source is the meat of large animals which have died. Soaring high in the sky allows condors to easily spot possible meals on the ground.Scientists worked together to study the flight patterns of these huge birds and how much effort the birds use when flying. To study the birds while they were in the sky, the researchers attached special devices which could record every beat of their wings.The scientists learned that most of the condors’ flapping— over 75%— came when the birds were taking off. Once in the sky, the birds flew for very long periods of time without flapping at all. In fact, they only flapped their wings for 1% of the time they were in the air. One bird flew for over five hours without flapping, covering nearly 117miles.Soaring without flapping is important because birds bum energy every time they flap their wings.The birds’ soaring isn’t magic. They use the fact that hot air rises to keep themselves up. As hot air rises, it often creates “thermals”— currents of warm air moving upward. The condors soar by making use of these thermals. The tricky part is finding thermals and moving between them.When birds are forced to land and take off again often, it costs them a lot of energy. The researchers learned that to avoid having to land, the condors did most of their non-take-off flapping when they were closer to the ground and looking for a new thermal.The scientists reported that even though all of the condors they studied were young, they knew well how to take advantage of the air currents.4. What can we learn about the Andean condor from the text?A. They live mairly on small animals.B. Their wingspan is at least three meters.C. They rely on hot air to remain high in the sky.D. They are the birds with the strongest flying ability.5. Why was the equipment tied to the birds?A. To measure how far they could fly without flapping.B. To keep track of how often they flapped while flying.C. To calculate the energy required for their flight.D. To confirm their flight patterns.6. Which of the following acts consumes the most energy for a condor?A. Hunting for food.B. Flying in the sky.C. Getting off the ground.D. Landing on the ground.7. What can we infer from the text?A. Condors flap the most when looking for a new thermal.B. No condor can fly for more than five hours without flapping.C. Condors don’t need to look for thermals when soaring in the sky.D. Soaring by using thermals is probably a natural ability of condors.CGuangzhououtbreak linked to strains inIndiaThe gene sequencing of the COVID-19 outbreak inGuangzhou.Guangdongprovince, indicates it is very similar in structure to the mutatedstrains detected inIndia, a senior health official from the city said on Sunday.“And it has the characteristic of quick spread.” Chen Bin, deputy director of the city's health commission, said at a news conference inGuangzhouon Sunday.She urged relevant departments and medical staff to act quickly to block the chain of infection and control the spread of the coronavirus in the southern metropolis.Zhang Zhoubin, deputy director of theGuangzhoucenter for disease control and prevention, said the strain of coronavirus spreads easily.“The virus can be spread through a meal or through a short period of indirect contact,” he said.The city reported five confirmed eases and 21 asymptomatic carriers as of 2 pm Sunday after the first con finned case was detected in the city's Liwan district on May 21, Chen said.To prevent the virus from spreading, the city government tightened its disease control and prevention measures over the weekend. Six communities and housing estates previously designated as low-risk areas were raised to medium-risk ones, Chen said.In addition to asking local residents to get vaccinated, the city has organized nucleic acid testing in Haizhu and Yuexiu districts starting from Sunday. Residents in specific areas of Tianhe, Baiyun and Panyu districts have also been required to take nucleic acid tests to expand the screening of suspected patients and asymptomatic carriers.Liwan previously required all its residents to take nucleic acid tests.As of Saturday, more than 2-25 million residents of the city have had samples collected for nucleic acid tests, Chen said. More than 10,000 medical workers from the entire city have been sent to Liwan to help vaccinate locals against COVID-19 and collect samples for nucleic acid testing.Deng Wenjun, director of circulation section with Guangzhou Supply and Marketing Cooperative, said there are sufficient supplies of food and daily necessities in the medium-risk areas.8. What is the characteristic of the COVID-19 which broke out inGuangzhou?A. It disappears quickly.B. It spreads fast.C. It has a lot to do with temperature.D. It has the same nature as the seasonal flu.9. Which district have residents who have not been required to take nucleic acid tests?A. Tianhe.B. Haizhu.C. Panyu.D. Zengcheng.10. Which of the following statements is TRUE?A. The virus can hardly be spread through a short period of indirect contact.B. There are 21 symptomatic carriers in the Liwan district as of 2 pm Sunday.C. All the people living in Liwan district arc previously asked to take nucleic acid tests.D. Supplies of food and daily necessities in the medium-risk areas arc still not enough.11. Where can you probably find this article?A. On a news website.B. In a fashion magazine.C. In a history book.D. In a travel journal.DWhere doyou usually put your toothbrush?Do you keep it in the bathroom? How’s your toothbrush looking these days? Even if you can’t see it with a naked eye, experts say it may be saturated(使饱和)with millions of toilet germs!Dr. Charles Oerba, a germ expert, is amicrobiology professor at the University of Arizona. He says there areapproximately 3 million bacteria per square inch in most toilet bowls, and every time you flush it without closing the lid, those millions of bacteria droplets spray into the air as far as twenty feet away and dirty everything in their path. And a common victim is your poor toothbrush, usually, left out on the bathroom sink, right?So, what do we do? Dr. Gerba says it’s easy. Close the toilet lid before you flush—that’ll greatly cut downthe germs, which will otherwise float in the air. And wash your toothbrush every few days in mouthwash or peroxide to get rid of any germs hiding in it. You can even put it through the dishwasher to sanitize(消毒)it. And always store your toothbrush in a closed cabinet.Here’s one more tip from Dr. Gerba, who says our kitchen sink is probably dirtier than our toilet. “If an alien came from space and studied the bacterial counts, he probably would conclude he should wash his hands in your toilet and go to the bathroom in your sink.” He says that’s because the kitchen sink is a great place where E. coli(大肠杆菌)to live and grow since it’s wet and damp. Bacteria feed on the food that people put down the drain or—that’s left on dishes in the sink. To reset your sink’s bacteria count back to zero, you’d better regularly wash it with hot water and sanitize yoursink with special chemicals. In fact, you may want to do it every day or before preparing dinner.12. What is the purpose of the text?A. To show how to brush your teeth.B. To tell people the importance of health.C. To warn people of the invisible germs.D. To introduce a microbiology professor.13. What can we learn from Paragraph 2?A. Bathroom sinks are the dirtiest places.B. Bacteria are bad for people’s health.C. Why bacteria spread through the air.D. How bacteria spread in the bathroom.14. What does the underlined word“that”in Paragraph 4 refer to?A. The food.B. The toothbrush.C. The sink.D. The chemical.15. Why does Dr. Gerba mention the example of an alien?A. To tell us a fiction story of an alien studying bacteria.B. To show our kitchen sink may be dirtier than our toilet.C. To teach us how to reset sink’s bacteria count back to zero.D. To prove coli prefers to live in the kitchen and the drain.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。

It was a lot of work but it was all worth it. I got blisters(水泡) from digging, and we all got insect bites, too.I learned a lot about gardening and collaboration(合作), and then I learned about the media. Our teacher telephoned the TV station and informed them of what we had accomplished. She spoke with the producer. The producer checked with the directors, but they said there were plenty of stories similar to ours. They wanted to know what was special about our particular garden, since many schools plant them.The teacher explained that, after going on the Internet to learn about the prairie(大草原), we had made a prairie garden. We had gone to a prairie and gotten seeds from the plants, and then we planted them. We did not water the garden, but we did weed it. We decided to let nature water it with rain, since that was how prairies grew in the past. We sent a picture of the garden to the news station. In the picture, the grass was so high that it stood taller than the fourth grade students.As a result, the producer sent a reporter to our school. He interviewed the headmaster and asked him many questions about the garden. After that, they interviewed us, and we explained to them what we had learned through this project.That night, we watched the news, and there we were. The news reporter told our story. It was only two minutes long, but it was us. We were famous. All that work, all those blisters, it was worth it. We knewthatwhen we saw the garden every day, but now we knew that the whole city thought so, too.4. What seemed to be the TV directors’ initial reaction to the garden?A. They were excited.B. They were surprised.C. They were worried.D. They were uninterested.5. What is special about the garden?A. Weeds were allowed to spread naturally.B. The grass grew faster than common grass.C. The seeds came from the plants of a prairie.D. Underground water was used for the plants.6. What does the underlined word “that” refer to in the last paragraph?A. We got blisters on our hands.B. Our hard work was worthwhile.C. The garden would be famous.D. The project would be finished.7. How did the author feel about the project?A. Annoyed.B. Curious.C. Proud.D. Regretful.CAsk a classroom of children to draw a scientist, and you’ll see plenty of color1 ed lab coats and glasses. The image (画像) hasn't changed much since the 1960s, but the person wearing the lab coat is changing.A new analysis finds that more female scientists have appeared in kids? drawings in recent decades — going from nearly nonexistent in the 1960s to about a third in 2016.The first of many “ draw-a-scientist ’’ studies asked nearly 5,000 children to draw a scientist between 1966 and 1977. Of those 5,000 drawings, only 28 drew female scientists. That was just 0.56 percent. Today, female scientists are being presented more in the media. For example, in a content analysis, 13 percent of people pictured in science feature stories of the 1960s were women or girls, compared with 44 percent in the 2000s. “That might really affect children’s idea on what a scientist should be like, ” says Miller, a Ph. D. candidate in psychology.To look for changes in children'sperceptionover time, the researchers conducted a meta-analysis ,combining data from 78 studies that included a total of more than 20,000 children from kindergarten to the 12th grade.On average, 28 percent of children drew female scientists in studies conducted from 1965 to 2016.What hasn’t changed much: kids pick up stereotypes (模式化观念）by gender (性别）as they grow up. At age 6, about 70 percent of the girls in the more recent studiesdrew female scientists. By age 16, 75 percent drew male scientists. This is an important period in which kids are learning stereotypes. It’s important that teachers and parents present diverse examples of both male and female scientists.8. What’s the picture of scientists drawn by a 1960s, kid like?A. A man with long curly hair.B. A woman with lab glasses.C. A woman in a formal lab suit.D. A man in a color1 ed lab coat.9. What may contribute to the changes in kids’ drawings?A. The improvement of women^ social status.B. The kids are affected by teachers and parents.C. More female scientists appear in the media.D. The increasing number of female scientists.10. What does the underlined word “ perception” in Paragraph 4 most probably mean?A. Belief.B. Idea.C. Habit.D. Growth.11. It can be inferred from the last paragraph that .A. it's a stereotype that scientists are generally malesB. girls are more influenced by stereotypes than boysC. some children are born with certain stereotypesD. most children tend to prefer female scientistsDThere is an old army joke about an officer who asks some soldiers whether any of them are interested in music. When four hands go up, the officer says, “Right, men. You can carry this grand piano down to the officers mess.”Job recruitment has become more complicated since that story first did the rounds. Today's careers require a lot more than just raw music but that sometimes makes jobs hard to define. An unfortunate result is a form of “adjective inflation” in recruitment ads as employers attempt to make routine tasks sound exciting.Candidates must sometimes wonder whether they are applying for a 9-to-5-role or to become a member of the Marvel “Avengers”. On Indeed, a job-bunting website, a bar was recently looking for "bartenders who are people focused, quality-driven, and have superhero hospitality powers". The ability to give customers the correct change was not mentioned.Another British company advertised for “a call-centre ninja, a superhero in people", a Job description which sounds a little over-the top for what was in fact a role at an insurance company in Isleworth. In case you think that ad was not typical. Indeed also had jobs demanding “ninja-like attention to detail". Short of turning up for the interview dressed head-to-toe in black, and then sneaking up behind the managing director at his desk, it is hard to see how candidates could show their ninja qualities.Not all companies require candidates to possess the qualities of a ninja, of course. Some require applicants to be passionate. The Bluewater shopping mall in southeastEnglandwas looking for “passionate sales-driven brand ambassadors” while “passionate crew members” were needed at a bakery in westLondonfor a wage of just £8. 23 an hour. In fact, passion is pretty hard to keep consistently for 40 hours a week, month after month. Job applicants should find some information from the kind of ads that companies place. If a job ad talks about passion or superheroes, run away faster than a speeding Batmobile. Being a ninja should be reserved for teenage mutant ninja turtles.12. Why does the author mention the joke in Paragraph 1?A. To show that officers enjoy playing tricks on soldiers.B. To introduce the topic of overstated job ads.C. To explain the origin of complex job ads.D. To describe soldiers' everyday life.13. Which of the following offers a job demanding ninja qualities?A. The bar.B. The bakery.C. The insurance company.D. The Bluewater shopping mall.14. What does the author say about the ads requiring passion?A. They are unrealistic.B. They are typical of want ads.C. They are appealing to applicants.D. They are uncommon on Indeed.15. How does the author sound when talking about today’s job ads?A. Curious.B. Hesitant.C. Humorous.D. Sympathetic.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。
