While it's easy enough to brush off a few sleepless nights with a pot of coffee and the occasional desk nap, you may be doing more harm than you realise. According to a new study from Surrey University, having less than six hours of sleep per night can actually shut down genes that play a key role in the body's 36 of self-repair.
We rely on our genes to constantly produce the proteins needed to 37 the wear on our bodies'tissue that we suffer throughout the day. But when scientists divided 26 volunteers into two groups—one of which slept for less than 6 hours per night for an entire week and the other for 10 hours per night—some of the sleep-deprived group's genes actually stopped working.
The functions of 711 genes in total were altered in some way, 38 ones involved in metabolism ( 新陈代谢), inflammation (炎症), immunity and stress. There is some good news though: a week of normal sleep was enough to 39 the malfunctioning genes back to peak condition, but should the40  sleep patterns continue, health problems that aren't, quite so easily reversible, like obesity (肥胖)and heart disease, have a 41 chance of cropping up. And this study only scratches the 42.
according to Professor Colin Smith, one of the scientists  43  in the study: This is only a week of sleep 44 and it is only five and a haft or six hours a night. Many people have that amount of sleep for weeks, months and maybe even years so we have no idea how much 45 it might be.

2. 根据下列材料,请回答36-1题:
Questions 36 to 45 are based Oil the following passage.
The concept of man versus machine is at least as old as the industrial revolution, but this phenomenon tends to be most acutely felt during economic downturns and slow recoveries. Since technology has such a big 36 for eating up human jobs, this phenomenon will continue to restructure our economy in ways we can't immediately foresee.
When there is exponential (指数的. 37 in the price and performance of technology, jobs that were once thought to be 38 from automation suddenly become threatened. This is a powerful argument, and a scary one. And yet, John Hagel, author of The Power of Pull and other books, says the argument misses the reason why these jobs are so vulnerable to technology in the first palce.
Hagel says we have designed jobs in the U.S. that tend to be tightly scripted and highly 39 ones that leave no room for individual initiative or creativity. In short, these are the types of jobs that machines can 40 much better than human beings. That is how we have put a giant 41 sign on the backs of
American workers.
It's time to 42 the formula for how work is conducted, since we are still relying on a very 20thcentury 43 of work, Hagel says. In our 44 changing economy, we more than ever need people in the workplace who can take initiative and exercise their imagination to respond to 45 events. That's not something machines are good at. They are designed to perform very predictable activities.


A.appetite
B.calculate
C.competition
D.distinct
E.exceedingly
F.immune
G.improvement
H.norm
I.notion
J.perform
K.rapidly
L.reinvent
M.standardized
N.target
O.unexpected

How to Reinvent College Rankings:Show the Data Students Need Most
A. All rankings are misleading and biased (有偏见的.. But they're also the only way to pick a school. I've heard those exact words dozens of times and inferred their sentiment hundreds more. They undoubtedly were a major contributing factor in the 250.000 applications to the too colleges this past year. With only 14,000 chances available, there will be a lot of disappointed families when decisions are announced in a few days. For 30 years, I've co-authored bestselling books and provocative articles about how to improve one's chances of being accepted at a "top" college.
B. The first edition of our book Getting In! revealed what went on behind the admission committees' closed doors,and introduced the concepts of packaging and positioning to the college-application vocabulary. The newest edition adapts the same principles to the digital age. But the core messagere mains: good colleges are not looking for the well-rounded kid--they're looking to put together thewell-rounded class.
C. What were revelations in 1983 are common knowledge today--at least among college-bound students, parents, and counselors. They also don't have to be told that the odds of getting into a "highly selective" school are ridiculously low. Brown and Dartmouth will each accept about 9 percent of applicants; Cornell, Northwestern, and Georgetown about 16 percent. And Harvard, Yale, and Stanford? Forget about it: less than 7 percent!
D. Wanting to attend a "name" school isn't illogical. And there is nothing illogical in parents wanting a better return on their investment. A college's brand value--whether that school's name will be recognized and open employers' door.
E. Colleges, counselors, and parents talk a lot about finding the right "fit" between a school and a student. In reality, the process is dominated by reputation. The problem is that college reputation shave been controlled by rankings. Far too many "highly ranked" colleges are gaming the rankings and trying to attract more and more applicants--when the particular college is actually a poor "fit" for many of the kids applying. Colleges want to attract and reject more kids because that "selectivity" improves the institution's ranking. College presidents publicly complain there are too many college rankings. Privately, they admit they have to provide the data that feed that maw (大胃口.. They can't afford to be left off a rankings list. The real losers in this system are students and their parents. A bad fit is costly, not just in dollars, but in time, energy, and psychological well-being.
F. The emphasis should be on finding the right fit. But finding the right fit is not east. Subjective guide books like Edward Fiske's--originally titled the New York Times Selective Guide to Colleges--are very useful and consciously do not include rankings. Ted changed his three-category rating system to make it more difficult to simply add "stars" and rank-list colleges. Even families who can afford to visit lots of colleges and endure the backward-walking tours find that carious personalities soon blur in their memory.
G. Thus it is not surprising that anxious, busy parents turn to rankings for shorthand comfort. Unfortunately, the data that U, S. News and other media companies are collecting are largely irrelevant. As a result, the rankings they generate are not meaningless, just misleading. Some examples: U. S. News places a good deal of emphasis on the percentage of faculty who hold a" terminal degree"--typically a Ph. D. Unfortunately, a terminal degree does not correlate (相关的.in any way with whether that professor is a good teacher. It also doesn't improve that professor's accessibility to students. In fact, there is usually such a correlation: the more senior the professor, the less time they have for undergraduates.
H. U.S. News' second most heavily weighted factor--after a college's six-year graduation rate--is a peer assessment of colleges by college presidents and admissions deans. You read that right: administrators are asked to evaluate colleges that are competitive with their own school. If not an complete conflict of interest, this measure is highly suspect.
I. Even some seemingly reasonable "inputs" are often meaningless. U.S. News heavily weights the number of classes with fewer than 20 students. But small classes are like comfort food., it is what high-school kids are familiar with. They have never sat in a large lecture hall with a very interesting speaker. So it is not something they could look forward or value.
J. While most rankings suffer from major problems in criteria(标准. and inputs, the biggest problem is simpler: all the ranking systems use weightings that reflect the editors' personal biases. Very simply,some editors' priorities are undoubtedly going be different from what is important to me. Assuredly preferences are different from my kids', And both will differ markedly from our neighbors' objectives.
K. Colleges say they truly want to attract kids for whom the school will be a good fit. To make good on that promise, colleges need to provide families with insight, not just information; and they need to focus on outputs, not. just inputs. Collecting and sharing four sets of very different data would be a good start; Better insight into the quality of education a student will get on that campus. Colleges need to share the exam scores for all students applying to medical school, law school, business school, and graduate programs. These tests reflect not just the ability of the kids who've gone to that college, but what they've learned in the three-plus years they've attended. Colleges need to assess a campus "happiness" coefficient (系数.. A happy campus is a more productive learning environment; and one that has a lower incidence of alcohol and drug abuse. The full debt that families incur (招致. ; not just student debt. The salaries of graduates one, five, and 10 years after graduation.
L. A fifth useful metric is what employers--both nationally and regionally--think of graduates from particular colleges. Hiring preferences are a useful proxy (代表.for reputation.
M. The last piece in enabling families to find a better fit will come from entrepreneurs. Some smart "kid" will develop an online tool that will allow students and parents to take this new college-reported data and assign weighting factors to the characteristics that are important to them. The tool would then generate a customized ranking of colleges that reflects the family's priorities--not some editor's.
N. Colleges may complain about the rankings, but they are complicit (串通一气的. in keeping them. It is reminiscent (怀旧的. of the classic Claude Raines line in Casablanca: "I'm shocked, shocked to find that gambling is going on in here!" ff colleges really want kids for whom their college is a good fit, they will collect and publish the types of honest data that will give families a better basis for smart decisions.


The rankings generated on the basis of data collected by U.S. News and other media companies are misleading.
5. Questions 36-61 are based on thefollowingpassage.   
   The flood of women into the job market boosted economic growth and changed U.S.society in many ways.Many in-home jobs that used to be done______36______by women—ranging from family shopping to preparing meals to doing______37______work—still need to be done by someone.Husbands and children now do some of these jobs,a______38______that has changed the target market for many products.Or a working woman may face a crushing“poverty of time”and look for help elsewhere,creating opportunities for producers of frozen meals,child care centers,dry cleaners,financial services,and the like.
   Although there is still a big wage______39______between men and women,the income working women______40______gives them new independence and buying power.For example,women now______41______about half of all cars.Not long ago,many cars dealers______42______women shoppers by ignoring them or suggesting that they come back with their husbands.Now car companies have realized that women are______43______customers.It’s interesting that some leading Japanese car dealers were the first t0______44______ pay attention to women customers.In Japan.fewer women have jobs or buy cars——the Japanese society is still very much male—oriented.Perhaps it was the______45______contrast with Japanese society that prompted American firms to pay more attention to women buyers.

第(36)题__________

6. Passage Two Questions{TSE} are based on thefollowingpassage.
    Acid rain,which is a form of air pollution,currently becomes a subject of great debate because of widespread environmental damage for which it has been blamed.It forms when oxides of sulfur(硫) and nitrogen(氮)combine with atmospheric moisture to yield sulfuric and nitric acids,which may then be carried long distances from their source before they drop in the form of rain.The pollution may also take the form of snow or fog or fall down in dry forms.In fact,although the term“acid rain”has been in use for more than a century——it is derived from atmospheric studies that were made in the region of Manchester,England—the more accurate scientific term would be“acid deposition”.The dry form of such deposition is just as damaging to the environment as the liquid form.
    The problem of acid rain originated with the Industrial Revolution,and it has been growing ever since.The severity of its effects has long been recognized in local settings,as exemplified by the spells of acid smog in heavily industrialized areas.The widespread destructiveness of acid rain,however,has become evident only in recent decades.One large area that has been studied extensively is northernEurope,where acid rain has eroded structures,injured crops and forests,and threatened life in freshwater lakes.In 1984,for example,environmental reports indicated that almost half of the trees in Germany’s Black Forest had been damaged by acid rain.The northeastem United States and eastern Canada have also been Darticularly affected by this form of pollution.Damage has also been detected in other areas of these countries and other regions of the world.
    Industial emissions have been blamed as the maj or cause of acid rain.Because the chemical reactions involved in the production of acid rain in the atmosphere are complex and as yet little understood.industries have tended to challenge such assessments and to stress the need for further studies and because of the cost of pollution reduction,governments have tended to support this attitude.
    Studies released by the USA government in the early 1980s,however,strongly indicated industries as the main source of acid rain,in the eastern USA and Canada.

From the first sentence of the passage,we Iearn that_____.
A.acid rain has caused air pollution
B.acid rain has caused widespread environmental damage
C.acid rain has become a much-studied subject
D.acid rain travels in all directions before it rains down
