Yet over the past
23、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, computers, chemicals, and aerospace, nanotech is overhaulin
24、g 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 California Institute of Technology, titled “Theres Plenty of
25、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 particles.What accounts for the sudden acceleration of nano
26、technology? 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 three-letter IBM logo, thus proving Feynman right. The ent
27、ire 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 of specialized crystals, built up one molecular layer at a t
28、ime. 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 an impossible task, until one realizes that evolution solve
29、d 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 motors may be re-engineered, or imitated, to produce products a
30、nd 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 the right shape and chemical binding preferences to ensure
31、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 able to find each other easily.（分数：10.00）(1).It can be inferr
32、ed 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 Almaden Research Center.C.Scientists manipulating atoms and “spra
33、y 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 computer(4).Which of the following is the function that nan
34、oscale 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 EXCEPT _ .（分数：2.00）A.The two strands making up DNAs double h
35、elix 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 them how to assemble individual molecules into new materialsD
36、.The read-head components for computer hard drives are constructed by means of the technology known as a molecular beam epitaxyBPassage 2/BWith the US economy slowing down, layoffs are everywhere. No industry is spared. If you end up having to start over, in addition to starting your job search, the
37、re 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, were fired or were laid off due to budget cutbacks, make sure you both have t
38、he 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 emergency cash that you can use in the interim. Dont panic and liquidate your st
39、ocks 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 out at restaurants and watch videos rather than going to the movies every w
40、eekend. 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 (unless you left a job willingly or was a college graduate looking for your
41、 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 Reconciliation Act (COBRA) in the United States that legally protects an
42、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 insurance at all.Another important thing to take care of when you change jobs
43、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, and the money accumulated will be managed by the 401(k) fund manager your
44、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-employer for a while. Its always a good idea to compare your new employers 401
45、(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 to go to the human resources department and ask for forms that help you ma
46、ke 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 with the friends you have made at your old job. Remember to anchor yourse
47、lf 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.each and every company spares no effort to survive the fierce competitionC.“c
48、ompulsory 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.emergency(3).Whats the point of saving the receipts of job-searching expense?（分数
49、：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 expense.(4).COBRA ensures an ex-employee stay in the health care plan _ .（分数：2.00）A.as long as the ex-employer
