A(2016 课标全国Ⅰ )You probably know who Marie Curie was, but you may not have heard of Rachel Carson. Ofthe outstanding ladies listed below, who do you think was the most important woman of the past 100 years?Jane Addams(1860 —1935)Anyone who has ever been helped by a social worker has Jane Addams to thank.Addams helped the poor and worked for peace. She encouraged a sense of community(社区)by creating sheltersand promoting education and services for people in need. In 1931, Addams became the firstAmerican woman to win the Nobel Peace Prize.Rachel Carson(1907—1964)If it weren’t for Rachel Carson, the environmental movement migh t not exist today. Her popular 1962 book Silent Spring raised awareness of the dangers of pollution and the harmfuleffects of chemicals on humans and on the world’s lakes and oceans.Sandra Day O’Connor(1930—present)When Sandra Day O’Connor finished thir d in her class at Stanford Law School, in 1952,she could not find work at a law firm because she was a woman. She became an Arizona statesenator(参议员)and, in 1981, the first woman to join the U.S. Supreme Court. O’Connor gave the deciding vote in many important cases during her 24 years on the top court.Rosa Parks(1913 —2005)On December 1,1955, in Montgomery, Alabama, Rosa Parks would not give up her seat on abus to a white passenger. Her simple act landed Parks in prison. But it also set off theMontgomery bus boycott.

Since March 2012, I’ve done 89 trips—of those, 51 have been abroad. I have 42 hours to carry stem cells(干细胞) in my little box because I ’ve got two ice packs and that’s how long they last. In all, from the time the stem cellsare harvested from a donor(捐献者)to the time they can be implanted in the patient, we’vegot 72 hours at most. So I am always conscious of time.I had one trip last year where I was caught by a hurricane in America. I picked up thestem cells in Providence, Rhode Island, and was meant to fly to Washington then back to London. But when I arrived at the check-in desk at Providence, the lady on the desk said:“ Well,I ’m really sorry, I’ve got some bad news for you—there are no flights from Washington.” So I took my box and put it on the desk and I said: “In this box are some stem cells that are urgently needed for a patient—please, please, you’ve got to get me back to t he United Kingdom.” She just dropped everything. She arranged for a flight on a small plane to be held for me,re-routed(改道)me through Newark and got me back to the UK even earlier than originallyscheduled.For this courier job,you ’re consciously aware that in that box you’ve got something that is potentially going to save somebody’s life.25.Which of the following can replace the underlined word“ courier”in Paragraph 1?A.providerB.delivery manC.collectorD.medical doctor26.Why does Peter have to complete his trip within 42 hours?A.He cannot stay away from his job too long.B.The donor can only wait for that long.C.The operation needs that much time.D.The ice won ’t last any longer.27.Which flight did the woman put Peter on first?A.To London.B.To Newark.C.To Providence.D.To Washington.C(2018 课标全国Ⅱ ,D)We’ve all been there:in a lift, in line at the bank or on an airplane, surrounded by people who are, like us, deeply focused on their smartphones or, worse, struggling with theuncomfortable silence.What’s the problem?It ’s possible that we all have compromised conversationalintelligence. It ’s more likely that none of us start a conversation because it ’s awkward and challenging, or we think it ’s annoying and unnecessary. But the next time you find yourself among strangers, consider that small talk is worth the trouble. Experts say it ’s an invaluable social practice that results in big benefits.Dismissing small talk as unimportant is easy, but we can’t forget that deep relationships wouldn’t even exist if it weren ’t for casual conversation. Small talk is the grease( 润滑剂 )for social communication, says Bernardo Carducci, director of the Shyness Research Institute at Indiana University Southeast. “ Almost every great love story and each big business dealbegins with small talk, ” he explains. “ The key to successful small talk is learning how toconnect with others, not just communicate with them. ”In a 2014 study, Elizabeth Dunn, associate professor of psychology at UBC, invited people on their way into a coffee shop. One group was asked to seek out an interaction( 互动 )with its waiter;the other, to speak only when necessary. The results showed that those who chatted with their server reported significantly higher positive feelings and a better coffee shopexperience. “It ’s not that talking to the waiter is better than talking to your husband, ”says Dunn. “ But interactions with peripheral( 边缘的 )members of our social network matter forour well-being also. ”Dunn believes that people who reach out to strangers feel a significantly greater senseof belonging, a bond with others. Carducci believes developing such a sense of belonging starts with small talk.“ Small talk is the basis of good manners,” he says.28.What phenomenon is described in the first paragraph?A.Addiction to smartphones.B.Inappropriate behaviours in public places.C.Absence of communication between strangers.D.Impatience with slow service.29.What is important for successful small talk according to Carducci?A.Showing good manners.B.Relating to other people.C.Focusing on a topic.D.Making business deals.30.What does the coffee-shop study suggest about small talk?A.It improves family relationships.B.It raises people’s confidence.C.It matters as much as a formal talk.D.It makes people feel good.31.What is the best title for the text?A.Conversation CountsB.Ways of Making Small TalkC.Benefits of Small TalkD.Uncomfortable SilenceD(2017 课标全国Ⅰ ,D)A build-it-yourself solar still(蒸馏器) is one of the best ways to obtain drinking waterin areas where the liquid is not readily available. Developed by two doctors in the U.S.Department of Agriculture, it’s an excellent water collector. Unfortunately, you must carrythe necessary equipment with you, since it’s all but impossible to find natural subs titutes. The only components required, though, are a 5'× 5' sheet of clear or slightly milky plastic,six feet of plastic tube, and a container—perhaps just a drinking cup—to catch the water. These pieces can be folded into a neat little pack and fastened on your belt.To construct a working still, use a sharp stick or rock to dig a hole four feet acrossand three feet deep. Try to make the hole in a damp area to increase the water catcher’sproductivity. Place your cup in the deepest part of the hole. Then lay the tube in place sothat one end rests all the way in the cup and the rest of the line runs up—and out—the side of the hole.Next, cover the hole with the plastic sheet, securing the edges of the plastic with dirtand weighting the sheet’s center dow n with a rock. The plastic should now form a cone(圆锥体 ) with 45-degree-angled sides. The low point of the sheet must be centered directly over,and no more than three inches above, the cup.The solar still works by creating a greenhouse under the plastic.Ground water evaporates(蒸发 ) and collects on the sheet until small drops of water form, run down the material, and falloff into the cup. When the container is full, you can suck the refreshment out through thetube, and won ’t have to break down the still ev ery time you need a drink.32.What do we know about the solar still equipment from the first paragraph?A.It ’s delicate.B.It ’s expensive.C.It ’s complex.D.It ’s portable.33.What does the underlined phrase“the water catcher” in paragraph 2 refer to?A.The tube.B.The still.C.The hole.D.The cup.34.What is the last step of constructing a working solar still?A.Dig a hole of a certain size.B.Put the cup in place.C.Weight the sheet’s center down.D.Cover the hole with the plastic sheet.35.When a solar still works, drops of water come into the cup from.A.the plastic tubeB.outside the holeC.the open airD.beneath the sheet第二节 ( 共 5 小题 ; 每小题 2 分 , 满分 10 分)(2018 课标全国Ⅱ )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。

It is a romantic story.BThe deadliest mass shooting committed by an individual in the us left 58 people dead and hundreds wounded at a country music festival in Las Vegas on October 1.Smith was at the festival to celebrate his brother’s 43 rd birthday.When the gunshots started,Smith initially thought they were fireworks.Soon he got separated from his family.As he turned back toward the stage to look for them,he saw people crowd behind a car at the northwest edge of the concert lawn.Others were so frightened that they didn’t know what to do.“Active shooter,active shooter,let’s go! We have to run.”he repeatedly shouted.He grasped people and told them to follow him toward a parking area in the direction of the airport,away from Las Vegas Avenue.A few girls weren’t fully hidden.The copy machine repairman from Orange County,California ,stood up and moved toward them to urge them to get on the ground.That’s when a bullet(子弹) struck him in the neck.Smith believes an off-duty San Diego police officer saved his life.The officer came over and tried to stop the bleeding and then signaled passing cars to try to get Smith a ride.By the time Smith got into a vehicle,he was struggling to breathe.Surgeons found it too risky to remove the bullet from his neck.Smith may have to live with it for the rest of his life.His courageous actions helped his photos go viral on Twitter and Reddit.A photo of Smith has been shared more than 74,000 times,with 177,000“likes”.“I don’t see myself that way,”he said.“I would want someone to do the same for me.No one deserves to lose a life coming to a country festival.” 24.Why did Smith go to the music festival?A.To enjoy fireworks.B.To gather with his family.C.To meet his favourite singers.D.To celebrate his brother’s birthday.25.How did Smith save the people behind a car?A.By directing them to the airport.B.By blocking bullets with his body.C.By taking them to a safe parking lot.D.By pressing them to lie on the ground.26.The surgeons didn’t remove the bullet in Smith’s neck in order to________.A.1et it fall out naturally B.avoid doing harm to himC.make it stop the bleeding D.use it as a reminder of safety27.What do Twitter and Reddit users think of Smith?A.He is a heroic figure.B.He is a modest person.C.He is an Internet addict.D.He is an ambitious dreamer.CThe world’s most complex biological computer, made from a group of engineered cells, could one da y be implanted into the body to detect diseases and deliver treatments.In an early research in 2012, Martin Fussenegger at ETH Zurish in Switzerland and his colleagues engineered two kidney cells to become a biological circuit capable of simple mathematics. One of the cells was able to calculate addition: the presence or absence of each of two chemicals would switch on a reactioninside the cell that would make it shine different colours. The other cell worked in the same way but could subtract amounts. This kind of biological circuit resembles a simple logic circuit in a computer. In theory, it could be used to indicate the presence of an infectious substance while in fact it failed.Most biological reactions in the body aren’t that simple, though. They rarely rely on “one input and one output” – instead, multiple inputs lead to different outputs. For instance, a high level of calcium in the body in the presence of a specific hormone may suggest one disease, but a high level of calcium along with another hormone might indicate a completely different condition.To be more practical, biological computers need to be able to perform more complex mathematics. However, it is hard to pack multiple calculations into a single cell. To get around this, Fussenegger and his team have engineered a multicellular system, in which different cells each perform a separate calculation and pass on the results to each other.The system has nine cells, each containing a biochemical reaction that responds to three chemical inputs – similar to an AND, NOT and OR system in a traditional electronic circuit. These cells coordinate their activities by releasing chemicals that pass from one cell to the other. Together, they form a fully biological circuit that can respond to multiple inputs.“Although it is not at a stage yet where we can test on animals, we believe it is the most complex biological computer ever assembled,” says Fussenegger. “This work addresses one of the major limitations in synthetic biology (合成生物学) –a lack of programmable devices,” says Ángel Goni-Moreno, a synthetic biologist at Newcastle University, UK. He says that Fussenegger’s multicellular approach enables you to programme the circuit and achieve different calculations just by connecting the nine cells in different configurations (设置).In the future, a biological computer like this could be used to monitor more complex medical conditions. For example, it could respond to a rise in calcium, a drop in a hormone and an increase in a biomarker, which together would signal the presence of a specific type of cancer, help diagnose it and alert the user to seek appropriate treatment.28.

Certain cells were made capable of performing mathematics.30. What has made Fussenegger’s current multicellular system so special?A. It has all the functions of a traditional electronic circuit.B. It is programmable and able to perform different mathematics.C. It has successfully packed multiple calculations into a single cell.D. It has been tested through a series of experiments on animals.31. What is the best title for the passage?A. Smart cells indicating various cancersB. Electronic circuit made from multi-cellsC. Programmable cells implanted in human bodiesD. Biological computer made from human cellsD“Two centuries ago, Lewis and Clark left St. Louis to explore the new lands acquired in the Louisiana Purcha se,” George W. Bush said, announcing his desire for a program to send men and women to Mars. They made that journey in the spirit of discovery. America has ventured forth into space for the same reasons.”Yet there are vital differences between Lewis and C lark’s expedition and a Mars mission. First, they were headed to a place where hundreds of thousands of people were already living. Second, they were certain to discover places and things of immediate value to the new nation. Third, their venture cost next to nothing by today’s standards. A Mars mission may be the single most expensive non-wartime undertaking in U.S. history.Appealing as the thought of travel to Mars is, it does not mean the journey makes sense, even considering the human calling to explore. And Mars as a destination for people makes absolutely no sense with current technology.Present systems for getting from Earth’s surface to low-Earth orbit are so fantastically expensive that merely launching the 1,000 tons or so of spacecraft and equipment a Mars mission would require could be accomplished only by cutting health-care benefits, education spending, or other important programs—or by raising taxes. Absent some remarkable discovery, astronauts, geologists, and biologists once on Marscould do little more than analyze rocks and feel awestruck(敬畏的) staring into the sky of another world. Yet rocks can be analyzed by automated probes without risk to human life, and at a tiny fraction of the cost of sending people.It is interesting to note that when President Bush unveiled his proposal, he listed these recent major achievements of space exploration pictures of evidence of water on Mars, discovery of more than 100 planets outside our solar system, and study of the soil of Mars. All these accomplishments came from automated probes or automated space telescopes. Bush’s proposal, which calls for reprogramming some of NASA’s present budget into the Mars effort, might actually lead to a reduction in such unmanned science—the one aspect of space explorati on that’s working really well.Rather than spend hundreds of billions of dollars to hurl tons toward Mars using current technology, why not take a decade or two or however much time is required researching new launch systems and advanced propulsion (推进力)? lf new launch systems could put weight into orbit affordably, and advanced propulsion could speed up that long, slow transit to Mars, the dream of stepping onto the red planet might become reality. Mars will still be there when the technology is ready.32. What do Lewis and Clark’s expedition and a Mars mission have in common?A. Instant value.B. Human inhabitance.C. Venture cost.D. Exploring spirit.33. Bush’s proposal is challenged for the following reasons except that.A. its expenditure is too huge for the government to afford.B. American people’s well-being will suffer a lot if it is implementedC. great achievements have already been made in Mars exploration in AmericaD. unmanned Mars exploration sounds more practical and economical for the moment34. Which cannot be concluded from the passage?A. Going to Mars using current technology is quite unrealistic.B. A Mars mission will in turn promote the development of unmanned program.C. Bush’s proposal is based on thre e recent great achievements of space explorationD. The achievements in space exploration show how well unmanned science has developed.35. What is the main idea of the passage?A. Risky as it is, a Mars mission helps to retain Americas position as a technological leader.B. A Mars mission is so costly that it may lead to an economic disaster in America.C. Someday people may go to Mars but not until it makes technological sense.D. A Mars mission is unnecessary since the scientists once there won’t mak e great discoveries.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。
