1、Computer crimes
More and more, the operations of our business, governments, and financial institutions are controlled by information that exists only inside computer memories. Anyone clever enough to modify this information for his own purposes can reap substantial rewards. Even worse, a number of people who have done this and been caught at it have managed to get away without punishment.
It's easy for computer crimes to go undetected if no one checks up on what the computer is doing, but even if the crime is detected, the criminal may walk away not only unpunished but with a glowing recommendation from his former employers. Of course, we have no statistics on crimes that go undetected but it's disturbing to note how many of the crimes we do know about were detected by accident, not by systematic inspections or other security procedures. The computer criminals who have been caught may have been the victims of uncommonly bad luck.
For example, a certain keypunch operator complained of having to stay overtime to punch extra cards. Investigation revealed that the extra cards she was being asked to punch were for dishonest transactions. In another case, dissatisfied employees of the thief tipped off the company that was being robbed unlike other lawbreakers, who must leave the country, commit suicide, or go to jail, computer criminals sometimes escape punishment, demanding not only that they not be charged but that they be given good recommendations and perhaps other benefits. All too often, their demands have been met.
Why? Because company executives are afraid of the bad publicity that would result if the public found out their computer had been misused. They hesitate at the thought of a criminal boasting in open court of how he juggled the most confidential records right under the noses of the company's executives, accountants, and security staff. And so another computer criminal departs with just the recommendations he needs to continue his crimes elsewhere.
It is implied in the third paragraph that ____.【单选题】

A.many more computer crimes go undetected than are discovered

B.the rapid increase of computer crimes is a troublesome problem

C.most computer criminals are smart enough to cover up their crimes

D.most computer criminals who are caught blame their bad luck

正确答案:A

答案解析:文章的第三段指出，“究竟有多少计算机犯罪，我们没有确切的统计数字，令人不安的是很多计算机犯罪是偶然中被发现的，而不是系统的检查或者通过其他安全防范措施而发现的。”这说明A是正确的：没有被发现的计算机犯罪比被发现的计算机犯罪要多得多。

2、Smart Window
Windows not only let light in to cut down an electricity use for lighting, but the light coming through the window also provides heat. However, windows are not something people typically associate with being a cutting edge technology. Researchers are now working on new technologies that enable a window to quickly change from clear to dark and anywhere in between with a flip of a switch.
"It took us a long time to figure out what a window really is," says Claes Granqvist. He's a professor of solid-state physics at Uppsala University in Sweden. "It's contact with the outside world. You have to have visual contact with the surrounding world to feel well. " So, windows and natural light are important for improving the way people feel when they're stuck indoors.
Yet, windows are the weak link in a building when it comes to energy and temperature control. In the winter, cold air leaks in. When it's hot and sunny, sunlight streams in. All of this sunlight carries lots of heat and energy. And all of this extra heat forces people to turn on their air conditioners. Producing blasts of cold air, which can feel so refreshing, actually suck up enormous amounts of electricity in buildings around the world.
Windows have been a major focus of energy research for a long time. Over the years, scientists have come up with a variety of strategies for coating, glazing, and layering windows to make them more energy efficient. Smart windows go a step further. They use chromogenic technologies which involve changes of color.
Electrochromic windows use electricity to change color. For example, a sheet of glass coated with thin layers of chemical compound such as tungsten oxide works a bit like a battery. Tungsten oxide is clear when an electric charge is applied and dark when the charge is removed, that is, when the amount of voltage is decreased, the window darkens until it's completely dark after all electricity is taken away. So applying a voltage determines whether the window looks clear or dark.
One important feature that makes a smart window so smart is that it has a sort of "memory. " All it takes is a small jolt of voltage to turn the window from one state to the other. Then, it stays that way. Transitions take anywhere from 10 seconds to a few minutes, depending on the size of the window. The development of smart windows could mean that massive air conditioning systems may no longer need. "In the future," Granqvist says, "our buildings may look different.
Which of the following statements does not indicate the importance of windows as described in the first two paragraphs?
【单选题】

A. Windows can change from clear to dark to save energy.

B.Windows help to save energy by letting light in.

C.Windows help to save energy by providing heat.

D.Windows enable people to have contact with the outside world.

正确答案:D

It can be concluded from the passage that ____.【单选题】

A.it is still impossible to detect computer crimes today

B.computer crimes are the one of most serious problem in the operation of financial institutions

C.computer criminals can escape punishment because they can't be detected

D.people commit computer crimes at the request of their company

正确答案:B

答案解析:首先根据第二段可知，A是错误的，因为计算机犯罪不是不能发现的。C：用计算机犯罪的罪犯可以逃脱惩罚，因为他们不会被发现，D：利用计算机犯罪的人是应他们公司的要求这样做的，都是错误的，文中没有提到。只有B： 计算机犯罪是金融机构里最严重的问题，是在文中第一段中暗示了的。因此选B。

4、Egypt Felled by Famine
Even ancient Egypt's mighty pyramid builders were powerless in the face of the famine that helped bring down their civilization around 2180 BC. Now evidence gleaned from mud deposited by the River Nile suggests that a shift in climate thousands of kilometers to the south was ultimately to blame and the same or worse could happen today.
The ancient Egyptians depended on the Nile's annual floods to irrigate their crops. But any change in climate that pushed the African monsoons southwards out of Ethiopia would have diminished these floods.
Dwindling rains in the Ethiopian highlands would have meant fewer plants to stablize the soil. When rain did fall it would have washed large amounts of soil into the Blue Nile and into Egypt, along with sediment from the White Nile.
The Blue Nile mud has a different isotope signature from that of the White Nile. So by analyzing isotope differences in mud deposited in the Nile Delta, Michael Krom of Leeds University worked out what proportion of sediment came from each branch of the river.
Krom reasons that during periods of drought, the amount of the Blue Nile mud in the river would be relatively high. He found that one of these periods, from 4,500 to 4,200 years ago, immediately predates the fall of the Egypt's Old Kingdom.
The weakened waters would have been catastrophic for the Egyptians. " Changes that affect food supply don't have to be very large to have a ripple effect in societies," says Bill Ryan of the Lamont Doberty Earth Observatory in New York.
"Similar events today could be even more devastating," says team member Daniel Stanley, a geoarchaeologist from the Smithsonian Institution in Washington, D C. " Anything humans do to shift the climate belts would have an even worse effect along the Nile system today because the populations have increased dramatically. "
Which of the following factors was ultimately responsible for the fall of the civilization of ancient Egypt?
【单选题】

A.Change of climate.

B.Famine.

C.Flood.

D.Population growth.

正确答案:A

答案解析:A：气候的变化。第一段中有这样一个子句… a shift in climate… was ultimately to blame…最终须归咎于气候的变化。在第一题的题解中，我们提到了“饥荒”与“古埃及文明毁灭”的关系。但“饥荒”是表层的因素，“气候的变化”才是古埃及文明毁灭的深层的因素。因此A是正确的答案。B：饥荒。C：水灾。D：人口增长。

5、Cooking Oil Fumes Cause Tumor
The leading cause of lung cancer among women in the city was cooking oil fumes while men are more likely to develop the disease from smoking, said medical experts after a fiveyear research study.
Doctors announced the results yesterday with analysis on some new tendencies in lung cancer, They said patients are younger, especially women.
According to the Shanghai Tumor research Institute, more local residents die of lung cancer in the city than anything else. Following breast cancer, it has the second-highest incidence rate.
"An unhealthy lifestyle is a very important reason for lung cancer," said Dr He Yumin from Shanghai Minshen Traditional Chinese Medicine Tumor Diagnosis and Treatment Center.
He followed 2,276 lung cancer patients for five years. Among them, 1,433 were male.
Smoking causes 70 percent of cases among men while only 18 percent of female patients developed cancer from smoking or inhaling second-hand smoke, according to the report.
However, more than 60 percent of women with the disease had long term, close contact with strong oil fumes from cooking and complained about irritated eyes and throat.
About 32 percent of women fried foods in boiling oil in unventilated kitchens and about 25 percent of women's bedrooms were adjacent to the kitchen.
However, local women were surprised to learn cooking oil fumes could lead to cancer. Some claimed they may change food preparation methods.
"Unless my family and I don't eat at home every day, I must stay in the kitchen to cook," said Xu Li, a 45-year-old local woman. "I know the fumes are bad for the skin, but it is the first time I heard that it can result in lung cancer. I have already started frying less. "
Doctors said women's lung cancer had few links to personal health and physical condition, but was closely related to family cancer history, unhealthy dietary habits and weak immune systems.
Other experts agreed with him.
"Smoking is by far the biggest cause of lung cancer for men," said Dr. Tan Binyong, honorary president of the Respiratory Disease Institute at Fudan University's Medical College. "It's true that second-hand smoke and cooking fumes are the main causes among women. "
His research also warned people not to stand near of stalls selling fried foods due to the poor quality of oils used.
The chance of catching lung cancer is three times higher if exposed to the fume for a long time, experts said.
What symptoms may be complained of by most women with lung cancer after long term close contact with cooking oil fumes?【单选题】

A.Irritated eyes and throat.

B.Severe pain in both lungs.

C.Continuous cough and headache.

D.Difficulty in breathing.

正确答案:A

答案解析:细节考查题。答案参见第七段：However，more than 60 percent of women with the disease had long term, close contact with strong oil fumes from cooking and complained about irritated eyes and throat（60％以上患肺癌的妇女都长期接触厨房油烟并表示眼睛和喉咙疼痛难受）。故正确答案为A。
