高三英语定时训练三十参考答案

限时规范练30(模块五Unit3B)核心素养关键词:培养学生人与自然、和谐发展的素养能力意识一、阅读理解ABack-to-back hurricanes hit the U.S.Virgin Islands last fall and caused a lot of damage.The U.S.Army Corps of Engineers has collected more than 736,000 cubic yards of rubbish as they rush to clean up St.Thomas,St.John and St.Croix,the Virgin Islands’ three major islands,but there is no place to put it.Some of the rubbish is metal,some of it is wood and parts of buildings,but most of it is trees and other plants.The Army Corps will ship the metal to the U.S.mainland to be sold.After being cut up into small parts,wood and other rubbish will be sent there,too.But it is much harder to get rid of the trees and big plants.The Army Corps wanted to burn the plant waste.It is the cheapest way to get rid of it,which was done in New York and New Jersey after Hurricane Sandy in 2012.But people in the Virgin Islands thought it could harm their health and the health of the islands,too.The protest started on the island of St.John,which is circled by coral reefsand includes a big national park.People on St.Thomas and St.Croix joined in,too.Sending the plant waste to the mainland is not a goodidea,either.It includes insects that could create problems in other areas.In Puerto Rico,an island in the Caribbean Sea,the Army Corps is cutting plant waste into mulch (护根),which helps improve thesoil.People in the Virgin Islands like the idea.But there may not be enough space for all of it.And some people are tired of waiting.Raphael Munchez,whose home was damaged,is one of those people.“We need our government to get back on its feet,” he said.“It’s struggling right now.Nobody is worried about pollution right now.We are worried about getting all of this rubbish off the island.”1.What troubled the Army Corps in the Virgin Islands?A.The severe weather.B.The mountains of rubbish.C.The buildings in bad condition.D.The damage caused by Hurricane Sandy.2.What did people in the Virgin Islands think of burning the waste?A.It would not be fairly effective.B.It would not be environment-friendly.C.It would help them rebuild their islands.D.It would destroy coral reefs around the island.3.What is the government doing now to get rid of the plant waste?A.Burning it on St.Croix.B.Sending it to the mainland.C.Cutting all of it into mulch.D.Still waiting for a solution.4.What do Munchez’s words in the last paragraph suggest?A.There will be a quick fix.B.The burning ban wastes time.C.The government’s struggle is worthy.D.Pollution should be regarded as a big problem.BOn December 26,2004,hundreds of tourists relaxed on Sri Lanka’s Yala National Park’s beaches.But at mid-morning the park’s elephants began crying wildly and running away from the ocean and up a nearby hill.The puzzled keepers could tell the animals were worried about something.But what?What the keepers did not know was that a 30-foot wall of water was headed straight toward them.This tsunami had been caused by an earthquake more than 1,000 miles away in the Indian Ocean.When the huge wave hit the coast,it caused severe damage.Many people died.The elephants,however,were not swept away by the water.They stood safely on the hill.Scientists have long suspected that animals sense natural disasters before humans do.People have told stories of dogs refusing to go outside and sharks swimming to deeper waters before a hurricane.After the 2004 tsunami,people said they sawtigers,monkeys,and water buffalo escaping to higher ground before the waters rushed in.Even in the hardest-hit areas of southernAsia,there were few animal deaths.It’s unlikely that an animal’s so-called sixth sense comes from some magical power to see into the future.Experts believe that animals may be more sensitive than humans to changes in temperature and other environmental conditions that take place before a natural disaster.The elephants in Sri Lanka,for example,may have picked up vibrations (震动) from within the Earth,a sign that danger was coming.Because vibrations in the ground travel much faster than an ocean wave,the elephants may have felt the earthquake that caused the tsunami well before the tsunami itself came to the coast.A few scientists are calling for a system to track reports of strange behavior in people’s pets,hoping that these reports can serve as a warning system that a natural disaster is about to happen.But Marina Haynes,an animal behavior scientist at the Philadelphia Zoo,says,“It would be an unreliable way to predict disasters.It can be difficult to know what an animal is doing.Is the animal nervous because an earthquake is about to happen or is it frightened because there is an enemy nearby?5.What happened to the elephants in Sri Lanka’s Yala National Park on December 26,2004?A.They died in the natural disaster.B.They were disturbed by the tourists.C.They moved from the hill to the seaside.D.They behaved strangely before the tsunami.6.How did the author present animals’ sixth sense in Paragraph 3?A.By giving examples.B.By making comparisons.C.By showing research findings.D.By telling an interesting story.7.What is the main idea of Paragraph 4?A.The advantages of being sensitive.B.The influences of the natural disaster.C.How animals predict a natural disaster.D.How elephants make use of their sixth sense.8.What is Haynes’ attitude towards a warning system?A.Delighted.B.Doubtful.C.Hopeful.D.Disappointed.二、完形填空When I became CEO of a hospital,I feared one thing greatly —public speaking.I’ve always 1public speaking because I 2 thought I did it very

高三英语定时训练三十（时间：40分钟）一、阅读理解。

阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。

ANEW HAVEN,Connecticut——A surprise awaited students in Yale who showed up for Professor Laurie Santos’s class.They got slips of paper that said,“No class today.”There was only one rule for the students‘unexpected free time——They were not allowed to study,but to relax.Since exams and papers were coming up,everyone was tired and stressed.At this moment they were touched.With around applause,nine students hugged Santos,and two burst into tears.Yet,cancelling class was not just a break.It was also a challenge,as she was asking them to stop worrying about their grades,even if it was just an hour.One student went to the Yale University Art Gallery for the first time in her four years at Yale.A group of students went to a recording studio and played a new song.More people were outside,and more were smiling.That’s why about1,200students were taking Santos’s class,called“Psychology and the Good Life,”the largest class in Yale’s317-year history.Even non-Yale students had the chance to take Santos’s class. It was offered as an online course and she immediately became an Internet hit.Skyler Robinson,one of her students,was at a loss for a while about what to do during his break,and then decided to take a nap.“It was a great nap,”he commented. Santos designed the class after she realized that her students kept busy through long days that seemed far more depressing and joyless than her own college years.“They feel they’re in this crazy rat race.They’re working so hard that they can’t take a single hour off.That’s awful.”The ideas behind the class are simple.Santos said,“It is the hope that science can help students find peace among all the stresses and difficulties they face at college.”The lessons include showing more gratitude,performing acts of kindness and increasing social connections.The students really wanted to learn to lead a happy lifein a science-driven way.Santos also noted the psychological happening of “mis-wanting”,which led people to work towards the wrong goals in life.One week,Santo asked students to exercise.Another week,she wanted them to get more sleep.They worked hard to keep some new habits.Social science research led to many new understandings of how people find happiness.She thinks her class can change Yale,or rather,not just Yale.1．How did students respond to the cancelling class?A．They expressed their concern.B．They were at a loss what to do.C．They showed gratitude to the teacher.D．They were eager to study individually.2．How can we know Santo’s class was popular?A．From the attendence in her class.B．From the subject she taught.C．From the long history of Yale.D．From the release of the online course.3．What can students learn from Santos’s class?A．To develop good study habits.B．To let exercise become their routine.C．To better understand how to find happiness.D．To do something joyful during the stressful time.4．What can we infer from the text?A．Santos had a more stressful time in her college.B．Students would be in rat race after Santos’s class.C．Santos’s influence can reach a wider range of people.D．Santos is going to cancel more classes for better effects.BAs unpleasant emotions go,anxiety is the roughest.It's a vague, pit-of-the-stomach fear that sneaks up to you--that unease you get when your boss says that she needs to talk to you right away,when the phone rings at4:00a.m.,orwhen your dentist looks into your mouth and says"Hmm"for the third time.Lingering anxiety can keep you up at night,make you irritable,undermine your ability to concentrate,and ruin your appetite.And the constant state of readiness generated by anxiety---adrenaline pumping,heart racing,palms sweating--may contribute to high blood pressure and heart disease.How to prevent anxiety then?Meditate.Maybe you're just high-strung.If so,meditation(冥想)is worth a try.It cultivates a calmness that eases anxious feelings and offers a sense of control.A study at the University of Massachusetts found that volunteers who took an8-week meditation course were considerably less anxious afterward.People who are high-strung find that they are dramatically calmer with20minutes of meditation in the morning and another20minutes after dinner.Jog,walk,swim,or cycle.If you can't make time for meditation,be sure to make time for regular exercise.Exercise can have the same calming effect as meditation, particularly if it's something repetitive like running or swimming laps.Treatment?Remember to breathe.When you're anxious,you tend to hold your breath or breathe too shallowly.That makes you feel more anxious.Breathing slowly and deeply can have a calming effect.To make sure that you're breathing correctly,place your hand on your diaphragm(横膈膜),just below your rib cage(胸腔).Feel it rise with each inhalation(吸气)and fall with each exhalation.Let's say you are anxious about your competence on the job.Ask yourself"What, in particular,am I afraid that I'll mess up?"Maybe you’re afraid that you get further behind and miss your deadlines.Or maybe you're worried that you're blowing it whenever you present your ideas in meetings.Are your worries founded?Have you had several near misses with deadlines?Are your suggestions routinely rejected?If not,the anxiety is needless.If there is a real problem,work on a solution:Pace yourself to better meet deadlines,or join a public speaking class.5．Which of the following symptoms is NOT directly caused by anxiety?A．Lower in concentration.B．No appetite.C．Heart racing.D．High blood pressure. 6．According to the passage,what can be done to avoid anxiety? A．Exercising regularly.B．Keeping breath steady. C．Breathing with the help of hands.D．Adjusting the pace of life. 7．What is the last paragraph about?A．Anxiety at work and its solutions.B．People's anxiety about their capabilities. C．The reason for someone's incompetence.D．The function of public speaking class.COne man’s white bread is another man’s green vegetables.That’s the key from The Personalised Diet,a new book from Israeli authors Eran Segal and Eran Elinav.The authors say it’s time to admit to ourselves that one-size-fits-all diets don’t work,and when it comes to nutrition,it’s about doing what works best for your body,not catching the latest diet fashion.“For years,we’ve been trying to search for that silver-bullet diet and we’ve been miserably failing,”Segal said.“And that’s because the best diet for each person really has to be tailored to that individual.”They conducted a personalised nutrition project at Weizmann,where hundreds of volunteers agreed to have their blood sugar tested after meals.One participant in the study,a woman named Ruti,said she was surprised that it was tomatoes--not ice cream or candies--that were raising her blood sugar level.Ruti recalled,“I have now significantly reduced my intake of tomato and I’m feeling much more energetic, which still surprises me.I have already lost a couple of pounds,and I have high hopes that I have finally found the answer to my weight struggle,too.”The Israeli scientists found that some people can consume traditionally unhealthy foods with little or no rise in their blood sugar levels,while others have a stronger response,and therefore shouldn’t eat those foods.It’s those kinds of results that you can only find from a personalised diet.“What we were surprised to find out was just like any other food,there is no such thing as good bread,”Elinav said.“The response to bread was completelyindividualised.”8．What is suggested in the first sentence?A．Everyone has their own tastes.B．Nutrition serves your body best.C．People’s response to the same food is different.D．The latest diet doesn’t fit each person.9．What does“that silver-bullet diet”refer to?A．A diet that is low in fat.B．A diet that begins a new diet trend.C．A diet that works best for everyone.D．A diet that provides all the nutrition.10．Ruti’s example suggests that to control weight,one needs to.A．eat much fewer tomatoesB．control their blood sugar levelsC．struggle for weight loss constantlyD．eat according to his or her blood sugar level11．Why is Elinav’s opinion on bread mentioned in the last paragraph?A．To advise people not to eat unhealthy food.B．To stress the need of the personalised diet.C．To explain the popularity of white bread.D．To show the importance of good bread.DArchaeologists used DNA taken from a broken clay pipe stem found in Maryland to build a picture of an enslaved woman who died around200years ago and had origins in modern-day Sierra Leone.One researcher called the work“a mind-blower.”“In this particular context,and from that time period,I think it’s a first,”team member Hannes Schroeder told The Washington Post.“To be able to get DNA from an object like a pipe stem is quite exciting.Also it is exciting for descendant(后裔) communities.Through this technology,they’re able to make a connection not only to the site but potentially back to Africa.”The pipe stem was found at the Belvoir plantation in Crownsville,Maryland, where enslaved people lived until1864and where a likely slave cemetery was recently found.DNA taken from the pipe linked back to a woman either directly from or descended from the Mende people,who lived in west Africa,in an area now part of Sierra Leone.Julie Schablitsky,the chief archaeologist with the Maryland state highway administration,told The Post the discovery,based on saliva(唾液)absorbed into the clay pipe,was a“mind-blower”.She also said records show the existence of a slave trade route Sierra Leone to Annapolis,plied(定期往来)by British and American ships.“As soon as people stepped on those slave ships in Africa,”she said,“whether they were from Benin or whether they were from Sierra Leone,wherever they were from, that identity was lost.Their humanity is robbed.Who they are as a people has gone.”The new analysis is part of ongoing research around Belvoir that has given descendants of the people enslaved there new insight into the lives of their ancestors. Speaking to The Post,Nancy Daniels,a genealogist from Laurel,Maryland,who thinks she is a descendant of enslaved families from Belvoir but was not linked to the research on the pipe,called the discovery“overwhelming.”“I’m sitting here about ready to cry,”she said.“I’m sorry.I'm so happy...Thank God for the DNA．”This year,events and ceremonies are being held to mark the400th anniversary of the arrival of the first enslaved people in America,at Jamestown,Virginia,in1619. 12．What does the phrase“a mind-blower”in paragraphs1and4refer to?A．A surprise.B．A confusion.C．An excitement.D．A fascination.13．According to Hannes Schroeder,the pipe stem was of great significance because________.A．it was the first direct evidence that slaves living in Maryland were originally from AfricaB．it helped the archaeologists to draw a portrait of the enslaved womanC．it might contribute to identifying the birthplace of the descendant communitiesD．it contained genetic clues to the ancestral background of its owner 14．What can be inferred from the passage?A．The owner of the pipe once lived in what is now an area in west Africa. B．The history of slavery in America is an ongoing topic of concern. C．African slaves lost their identities when they arrived at the Belvoir plantation. D．Nancy Daniels,a genealogist was sorry for not being involved in the research. 15．Which of the following is the best title for the passage?A．DNA from an old pipe throws lights on the origins of the enslavedB．A new research reveals the origins of enslaved African womanC．The descendants of enslaved people seek their identitiesD．DNA contributes to the breakthrough of a new research二、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，选项中有两项为多余选项。
