1、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。

2、Human Heart Can Make New Cells
Solving a longstanding mystery, scientists have found that the human heart continues to generate new cardiac cells throughout the life span, although the rate of new cell production slows with age.
The finding, published in the April 3 issue of Science, could open a new path for the treatment of heart diseases such as heart failure and heart attack, experts say.
"We find that the beating cells in the heart, cardiomyocytes, are renewed," said lead researcher Dr. Jonas Frisen, a professor of stem cell research at the Karolinska Institute in Stockholm, Sweden. "It has previously not been known whether we were limited to the cardiomyocytes we are born with or if they could be renewed," he said.
The process of renewing these cells changes over time, Frisen added. In a 20-year-old, about 1 percent of cardiomyocytes are exchanged each year, but the turnover rate decreases with age to only 0. 45 percent by age 75,
"If we can understand how the generation of new cardiomyocytes is regulated, it may be potentially possible to develop pharmaceuticals that promote this process to stimulate regeneration after for example, a heart attack, "Frisen said.
That could lead to treatment that helps restore damaged hearts.
A lot of people suffer from chronic heart failure," noted co-author Dr. Ratan Bhardwaj.
Ratan Bhardwaj, also from the Karolinska Institute. "Chronic heart failure arises from heart cells dying," he said.
With this finding, scientists are "opening the door to potential therapies to having ourselves heal ourselves," Bhardwaj said. "Maybe one could devise a pharmaceutical agent that would make heart cells make new and more cells to overcome the problem they are facing. "
But barriers remain. According to Bhardwaj, scientists do not yet know how to increase heart cell production to a rate that would replace cells faster than they are dying off, especially in older patients with heart failure. In addition, the number of new cells the heart produces was estimated using healthy hearts-whether the rate of cell turnover in diseased hearts is the same remains unknown.
The finding could prove to be useful to ____.【单选题】

A.the analysis of cardiac cells

B.the prevention of chronic diseases

C.the treatment of heart disease

D.the study of longstanding mysteries

正确答案:C

答案解析:根据是第二段中:The finding,…,could open a new path for the treatment of heart diseases这一研究成果将为心脏病的医治开拓新的途径。

3、The Only Way Is Up
Think of a modem city and the first image that come to mind is the skyline. It is full of great buildings, pointing like fingers to heaven. It is true that some cities don't permit buildings to go above a certain height. But these are cities concerned with the past. The first thing any city does when it wants to tell the world that it has arrived is to build skyscrapers.
When people gather together in cities, they create a demand for land since cities are places where money is made, that demand can be met. And the best way to make money out of city land is to put as many people as possible in a space that covers the smallest amount of ground that means building upwards.
The technology existed to do this as early as the 19th century. But the height of buildings was limited by one important factor. They had to be small enough for people on the top floors to climb stairs. People could not be expected to climb a mountain at the end of their journey to work, or home.
Elisha Otis, a US inventor, was the man who brought us the lift or elevator, as he preferred to call it. However, most of the technology is very old lifts work using the same pulley system the Egyptians used to create the Pyramids. What Otis did was attach the system to a steam engine and develop the elevator brake, which stops the lift falling if the cords that hold it up are broken. It was this that did the most to gain public confidence in the new invention. In fact, he spent a number of years exhibiting lifts at fairgrounds, giving people the chance to try them out before selling the idea to architects and builders.
A lift would not be a very good theme park attraction now. Going in a lift is such an everyday thing that it would just be boring. Yet psychologists and others who study human behavior find lifts fascinating. The reason is simple. Scientists have always studied animals in zoos. The nearest they can get to that with humans is in observing them in lifts.
"It breaks all the usual conventions about the bubble of personal space we carry around with us and you just can't choose to move away," says workplace psychologist, Gary Fitzgibbon. Being trapped in this setting can create different types of tensions, he says. Some people are scared of them. Others use them as an opportunity to get close to the boss. Some stand close to the door. Others hide in the comers. Most people try and shrink into the background but some behave in a way that makes others notice them. There are a few people who just stand in a comer taking notes.
Don't worry about them. They are probably from a university.
Psychologists find the lift a good place where they can study human behavior because____.【单选题】

A.here humans behave the way animals do

B.people in a lift are all scared

C.here some people take notes

D.in a lift the bubble of personal space breaks

正确答案:D

答案解析:电梯的空间狭小,相对拥挤,人们想要享有私人空间的要求在这里成了幻想,如同关在动物园的笼子里的动物一般,这为心理学家提供了一个研究在这种情况下人的行为的难得的机会。

4、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.
The underlying reason for the computer criminals to get recommendations he needs is that ____.【单选题】

A.they have skills formidably difficult for others to master

B.the employers are afraid that they would take avenge if punished

C.the employers are much afraid of bringing the public into disbelief towards them through the criminals words in open court

D.those who commit crimes do not mean bad

正确答案:C

答案解析:雇主对计算机犯罪者的宽容可能有各种原因。A、B、C、D所说的情形,在现实中都可以出现,但文中提到的只有C项,参见末段。

5、The Iceman
On a September day in 1991, two Germans were climbing the mountains between Austria and Italy. High up on a mountain pass, they found the body of a man lying on the ice. At that height (10,499 feet, or 3 ,200 meters) , the ice is usually permanent, but 1991 had been an especially warm year. The mountain ice had melted more than usual and so the body had come to the surface.
It was lying face downward. The skeleton (骨架) was in perfect condition, except for a wound in the head, There was still skin on the bones and the remains of some clothes. The hands were still holding the wooden handle of an ax and on the feet there were very simple leather and cloth hoots. Nearby was a pair of gloves made of tree bark (树皮) and a holder for arrows.
Who was this man? How and when had he died? Everybody had a different answer to these questions. Some people thought that it was from this century, perhaps the body of a soldier who died in World War I, since several soldiers had already been found in the area. A Swiss woman believed it might be her father, who had died in those mountains twenty years before and whose body had never been found. The scientists who rushed to look at the body thought it was probably much older, maybe even a thousand years old.
With modern dating techniques, the scientists soon learned that the Iceman was about 5,300 years old. Born in about 3300 B. C. , he lived during the Bronze Age in Europe. At first scientists thought he was probably a hunter who had died from an accident in the high mountains. More recent evidence, however, tells a different story, A new kind of X - ray shows an arrowhead still stuck in his shoulder. It left only a tiny hole in his skin, but it caused internal damage and bleeding. He almost certainly died from this wound, and not from the wound on the back of his head. This means that he was probably in some kind of a battle. It may have been part of a larger war, or he may have been fighting bandits. He may even have been a bandit himself.
By studying his clothes and tools, scientists have already learned a great deal from the Iceman about the times he lived in. We may never know the full story of how he died, but he has given us important clues to the history of those distant times.
The body of the Iceman was found in the mountains mainly because ______.【单选题】

A.two Germans were climbing the mountains

B.the melted ice made him visible

C.he was lying on the ice

D.he was just on a mountain pass

正确答案:B

答案解析:本题是细节题,难度不大,针对文章第一段出题,比较容易找到答案依据。文中第一段最后谈到,由于1991年特别暖和,山上的冰比原来化的要多,所以尸体就露出来了,回来看选项,找信息提示,答案是B。
