23、ubt encountered the term nanotechnology. Yet over the past year also, a series of breakthroughs have transformed nanotech from sci-fi fantasy into a real world. Applied science, in the process, inspired huge investments by business, academia, and government. In industries as diverse as health care,

24、computers, chemicals, and aerospace, nanotech is overhauling production techniques, resulting in new and improved products, some of which may already be in your home or workplace.The inspiration for nanotech goes back to a 1959 speech by the late physicist Richard Feynman, then a professor at the Ca

25、lifornia Institute of Technology, titled “Theres Plenty of Room at the Bottom. “ Four decades later, Chad Mirkin, a Chemistry professor at Northwestern Universitys $ 34 million nanotech center, used a nanoscale device to etch most of Feynmans speech onto a surface the size of about 10 tobacco smoke

26、particles.What accounts for the sudden acceleration of nanotechnology? A key breakthrough came in 1990, when researchers at IBMs Almaden Research Center succeeded in rearranging individual atoms at will. Using a device known as a scanning probe microscope, the team slowly moved 35 atoms to spell the

27、 three-letter IBM logo, thus proving Feynman right. The entire Logo was less than three nanometers.Soon, scientists were not only manipulating individual atoms but “spray painting“ with them as well. Using a tool known as a molecular beam epitaxy, scientists have learned to create ultra fine films o

28、f specialized crystals, built up one molecular layer at a time. This is the technology used today to build read-head components for computer hard drives.The next stage in the development of nanotechnology borrows a page from nature. Building a supercomputer no bigger than a speck of dust might seem

29、an impossible task, until one realizes that evolution solved such problems more than a billion years ago. Living cells contain all sorts of nanoscale motors made of proteins that perform myriad mechanical and chemical functions, from muscle contraction to photosynthesis. In some instances, such moto

30、rs may be re-engineered, or imitated, to produce products and processes useful to humans.How are these biologically inspired machines constructed? Often, they construct themselves, manifesting a phenomenon of nature known as self assembly. The macromolecules of such biological machines have exactly

31、the right shape and chemical binding preferences to ensure that when they combine they will snap together in predesigned ways. For example, the two strands that make up DNAs double helix match each other exactly, which means that if they are separated in a complex chemical mixture, they are still ab

32、le to find each other easily.（分数：10.00）(1).It can be inferred that Richard Feynman has been _ now.（分数：2.00）A.deadB.decentC.prominentD.popular(2).Who proved that Feynmans concept, “Theres Plenty of Room at the Bottom“ was right?（分数：2.00）A.Chad Mirkin at Northwestern University.B.Researchers at Almade

33、n Research Center.C.Scientists manipulating atoms and “spray painting“.D.A professor at the California Institute of Technology.(3).Scientists created ultra fine films of specialized crystals by means of _ .（分数：2.00）A.a scanning probe microscopeB.a nanoscale deviceC.a molecular beam epitaxyD.a super

34、computer(4).Which of the following is the function that nanoscale motors perform?（分数：2.00）A.rearranging individual atoms.B.manipulating individual atoms.C.producing products and process.D.photosynthesis and muscle concentration.(5).According to the passage, all of the following statements are true E

35、XCEPT _ .（分数：2.00）A.The two strands making up DNAs double helix can find each other easily in a complex chemical mixtureB.Evolution has solved the problem of building a computer smaller than a speck of dust a long time beforeC.DNA not only programs cells to replicate themselves but also instructs th

36、em how to assemble individual molecules into new materialsD.The read-head components for computer hard drives are constructed by means of the technology known as a molecular beam epitaxy五、Passage 2(总题数：1，分数：10.00)With the US economy slowing down, layoffs are everywhere. No industry is spared. If you

37、 end up having to start over, in addition to starting your job search, there are several things you should take care of to make your transition a smooth one.First and foremost, clear up any misunderstanding about how and why you left your last job with your ex-boss. Whether you left voluntarily, wer

38、e fired or were laid off due to budget cutbacks, make sure you both have the same explanation. Agree on job titles accordingly. Also ask for a reference if you think your ex-boss will offer one and you trust that he or she will speak honestly about your performance.You should have a source of emerge

39、ncy cash that you can use in the interim. Dont panic and liquidate your stocks and bonds just yet, be optimistic in your prospects while also be more frugal than usual. You should save money on not having to dry clean work clothes so often and eating less take-out lunches. Save money by not eating o

40、ut at restaurants and watch videos rather than going to the movies every weekend. Make a note of your job hunting expenses, such as career counselors consulting fees and resume printing costs, and save the receipts. By next years tax-filing time, you could get deductions on your job-search expense (

41、unless you left a job willingly or was a college graduate looking for your first job).Most companies terminate your medical insurance coverage as soon as you stop working for them. But it doesnt mean you have to forgo medical coverage altogether. There is something called Consolidated Omnibus Budget

42、 Reconciliation Act (COBRA) in the United States that legally protects an ex-employees right to stay in the companys health care plan. However, the company will stop paying your premiums, and you will have to pay out of your pocket the expenses. This is still a good option compared to no health insu

43、rance at all.Another important thing to take care of when you change jobs is your 401(k) account. A 401(k) is the retirement fund that most companies offer. Its named after section 401(k) in the Internal Revenue Services policy documents. You put aside a percentage of your paycheck each pay period,

44、and the money accumulated will be managed by the 401(k) fund manager your employer has hired and is invested in the stock market. You cannot withdraw money from this account until you reach this age, or you will incur penalties. When you leave a job, the money can sometimes be kept with your ex-empl

45、oyer for a while. Its always a good idea to compare your new employers 401(k) plan with your old one. Every company offers different types of investment options, from overseas stocks to high-tech stocks and everything in between. If you do want to transfer the account to your new employer, you need

46、to go to the human resources department and ask for forms that help you make the transition.Dont forget to ask for job leads from your ex-coworkers. Even if you are leaving for a job in another industry, you never know what people they happen to know that can help with your job search. Keep in touch

47、 with the friends you have made at your old job. Remember to anchor yourself to people, not institutions, and you will find that any transition is made easier.（分数：10.00）(1).According to Paragraph 1, in the United States, _ .（分数：2.00）A.most industries stay unaffected by global economic recessionB.eac

48、h and every company spares no effort to survive the fierce competitionC.“compulsory redundancy“ is going on in every industryD.employees are laid off because they are not qualified for their jobs(2).The word “interim“ most probably means _ .（分数：2.00）A.intervalB.hard timeC.transitional periodD.emerge

49、ncy(3).Whats the point of saving the receipts of job-searching expense?（分数：2.00）A.To get reductions at tax-filing time.B.To keep a record of ones job hunting experience.C.To be aware of ones expenditure and be frugal.D.Because ones ex-boss will reimburse the job-searching expens(4).COBRA ensures an ex-employee stay in the health care
