共用题干第一篇Immune FunctionsThe immune system is equal in complexity to the combined intricacies of the brain and nervous system. The success of the immune system in defending the body relies on a dynamic regulatory communication net- work consisting of millions and millions of cells.Organized into sets and subsets,these cells pass information back and forth like clouds of bees flying around a hive（蜂巢）.The result is a sensitive system of checks and balances that produces an immune response that is prompt,appropriate,effective,and self-limiting.At the heart of the immune system is the ability to distinguish between self and nonself. When immune defenders encounter cells or organisms carrying foreign or nonself molecules,the immune troops move quicklyto eliminate the intruders（人侵者）.Virtually every body cell carries distinctive molecules that identify it as self. The body's immune defenses do not normally attack tissues that carry a self-marker. Rather,immune cells and other body cells coexist peaceably in a state known as self-tolerance.When a normally functioning immune system attacks a nonself molecule,the system has the ability to"remember"the specifics of the foreign body.Upon subsequent encounters with the same species of molecules,the immune system reacts accordingly. With the possible exception of antibodies（抗体）passed during lactation（授乳期）, this so called immune system memory is not inherited.Despite the occurrence of a virus in your family,your immune system must"learn"from experience with the many millions of distinctive nonseif molecules in the sea of microbes（微生物）in which we live. Learning entails producing the appropriate molecules and cells to match up with and counteract each nonseif invader.Any substance capable of triggering an immune response is called an antigen（抗原）.Antigens are not to be confused with illergens（过敏原）,which are most often harmless substances that provoke the immune system to set off the inappropriate and harmful response known as allergy.An antigen can be a virus,a bacte-rium,or even a portion or product of one of these organisms.Tissues or cells from another individual also act as antigens,because the immune system recognizes transplanted tissues as foreign,it rejects them.The body will even reject nourishing proteins unless they are first broken down by the digestive system into their primary,nonantigenic building blocks.An antigen announces its foreignness by means of intricate and charac- teristic shapes called epitopes（抗原表位）, which protrude（突出）from its surface. Most antigens , even the simplest microbes,carry several different kinds of epitopes on their surface;some may even carry several hundreds.Some epitopes will be more effective than others at stimulating an immune response.Only in abnormal situations does the immune system wrongly identify self as nonself and execute a misdirected immune attack.What is used to describe the communication network consisting of cells in the immune system?A:The immune system's memory.B:Immune troops sliminating intruders.C:Bees flying around a hive.D:A sea of microbes.

共用题干Using HIV Virus to Cure CancerScientists are planning to use human immuno deficiency（免疫缺陷）virus(HIV) , one of mankind's most feared viruses,as a carrier of genes which can fight cancer and a range of diseases that cannot be cured.The experts say HIV has an almost perfect ability to avoid the body's immune（免疫的）defenses, making it ideal for carrying replacement genes into patients'bodies,according to the Observer.A team at the California-based Salk Institute,one of the world's leading research centers on biological sciences,has created a special new breed of HIV and has started negotiations with the U.S.Food and Drug Administration(FDA)to begin clinical gene therapy（治疗）trials this year.The first trials are expected to involve patients suffering from cancers that cannot be cured by surgery although project leader Professor Inder Verma said the HIV technique would have“far wider applications”.The plan remains very likely to cause controversy since it involves making use of a viruswhich has caused more than 22 million deaths around the world in the past two decades.Verma said that the idea of using HIV for a beneficial purpose was“shocking”but the fierce nature of HIV had disappeared by having all six of the potentially deadly genes removed.Illnesses such as various cancers are caused when a gene in a patient's body fails to work properly.In the past two years, breakthroughs in genetics（遗传学）have led gene therapy sci-entists to try and replace the genes that do not function normally.Unfortunately,the body's immune defenses have been known to attack the modified genes and make them lose their effects before they can start their task and progress in the field has been held up by the lack of a suitable carrier.The HIV virus has the ability to escape from,and then destroy,the immune defense cells designed to protect our bodies and this makes it attractive to scientists as a way of secretly conveying replacement genes into patients'bodies.The HIV virus has caused more deaths in developed countries.A:RightB:WrongC:Not mentioned
资料：Keeping the Zeal of a Startup as You ScaleThere are many reasons that founder-led companies are so good at disrupting industries and making life miserable for slow-moving incumbents. But perhaps the most powerful is that founders create great insurgencies. They ignore established industry rules and boundaries. They create better ways to solve old problems. They disdain anything that blurs their focus on the front line. From top to bottom, they are at war against the industry leaders on behalf of undeserved customers.Our research on what we call the “founder’s mentality” shows that maintaining a strong insurgent mission is critical to long-term, sustainable growth. But to compete long term, insurgent companies also need to develop scale and scope, which very often dulls their insurgent’s zeal. In many ways, this is because their perspective on the future slowly changes. Insurgents see the days ahead—both long and short term—as ripe with opportunity. They embrace change and chaos. They invest in whatever it takes to innovate new solutions for customers. Incumbents, on the other hand, very often see the future as a threat. As leaders invested heavily in the status quo, innovation and disruption are not good for them. Turbulence erodes profitability; innovation marginalizes their current product offerings. The future is not better.The companies that find a way to achieve scale without losing their insurgent mission---we call them “Scale Insurgents”--remain acutely alert to this difference in perspective. They actively fight back against the very natural tendency to retreat behind the castle walls to avoid future change and turbulence. Instead, they do what in some companies might seem like heresy---they commit to disrupting their own insurgency. They know that acquiring the benefits of scale requires ruthless focus on a well-defined core business and a commitment to building the systems and processes to support it. But they aren’t wedded to their business model—they are wedded to what will serve their customers best. Rather than erecting defenses against the future, they embrace the notion of limitless horizons—the idea that a company can intelligently extend the boundaries of its core ever outward.In the author’s opinion,what is a “scale insurgents”?A.startup company that maintains its original quality in the process of scaling upB.An insurgent company that turned into an incumbent companyC.An insurgent company that managed to make steady profitsD.startup company that succeeded in scaling up
资料：The data a bank has stored on its servers is more valuable than the gold in its vaults. Banks enjoy a monopoly over data that has helped them get away with poor services and fend off competitors. In Europe, at least, that is all about to change with a new set of regulations, named PSD2.The rules will compel banks to share data easily with licensed third parties. Bankers in Europe complain that their profits and customer relationships are under threat. However, opening up banks, and the data they store, is good for consumers and competition, New providers will be better placed to offer all sorts of innovative services, such as a one-click option to put unspent monthly income into a pension plan.Nevertheless, some concerns about PSD2 are legitimate. In particular, it is reasonable to wonder about the privacy and security implications of sensitive financial date being shared with third parties. But banks themselves are hardly invulnerable to cyber attacks （网络攻击）.And the solutions that the European regulators propose to deal with these worries look promising. Third parties that want to use bank data will need to convince national regulators that their data defenses are solid and are subject to annual regulatory inspections.The gap between writing rules and implementing them is always large. First, consent from customers to provide access to their bank data must be gained explicitly, and the purposes of the data use should be clearly explained. Second, regulators must be very tough both in ensuring that banks open up their infrastructure and in withdrawing the licenses of third parties that break the rules. Third, regulators must also be flexible enough to allow for changes as the market evolves. Since the new entrants will not be licensed to engage in riskier financial activities——such as lending money——it makes sense to regulate them with a lighter touch. But if some Fintech providers do end up becoming systemically important, higher standards of oversight might be necessary.What is the passage mainly about？A.Challenges facing European regulators.B.A new regulation in Europe that opens banks to competition.C.The solutions to the flawed banking system in Europe.D.A looming threat to customers' private bank data.
共用题干HackingPeople tend to think of computers as isolated machines,working away all by themselves.Some do-personal computer without an outside link, like someone's hideaway（隐蔽的）cabin in the woods.But just as most of homes are tied to a community by streets,bus routes and electric lines,computers that exchange intelligence are part of a community-local,national and even global network joined by telephone connections.The computer network is a creation of the electric age,but it is based on old-fashioned trust. It cannot work without trust. A rogue loose（为所欲为的无赖）in a computer system called hacker（黑客）is worse than a thief entering your house. He could go through anyone's electronic mail or add to,change,distort or delete anything in the information stored in the computer's memory .He could even take control of the entire system by placing his own instructions in the software that runs it.He could shut the computer down whenever he wished,and no one could stop him.Then he could program the computer to erase any sign of his ever having been there.Hacking,our electronic- age term for computer break-in,is more and more in the news-brainy kids vandalizing university records, even pranking（胡闹）about in supposedly safeguard-ed systems.To those who understand how computer networks are increasingly regulating life in the late 20th century,these are not laughing matters.A potential for disaster is building:A dissatis- fled former insurance-company employee wipes out information from payroll（工资表）files. A student sends out a“virus”,a secret and destructive command,over a national network .The vi-rus copies itself at lightning speed,jamming the entire network-thousands of academic,commer-cial and government computer systems.Such disastrous cases have already occurred.Now exists the possibility of terrorism by computer. Spoiling a system responsible for air-traffic control at a busy airport,or knocking out the telephones of a major city,is a relatively easy way to spread panic .Yet neither business nor government has done enough to toughen its defenses against at-tack .For one thing,such defenses are expensive;for another,they may interrupt communica- tion—the main reason for using computers in the first place. One of the reasons why business or government has not taken tough measures to stop hacking is that______.A: it will cause fear among the publicB: hacking has not caused much damageC: tough measures are illegalD: communication may be interrupted
