单选题The fact that blind people can "see" things using other parts of their bodies apart from their eyes may help us to understand our feelings about color. If they can sense color differences then perhaps we, too, are affected by color unconsciously.
Manufacturers have discovered by trial and error that sugar sells badly in green wrappings, that blue foods are considered unpleasant, and the cosmetics (化妆品) should never be packaged in brown. These discoveries have grown into a whole discipline of color psychology that now finds application in oeverything from fashion to interior decoration. Some of our preferences are clearly psychological. Dark blue is the color of the night sky and therefore associated with passivity and calm, while yellow is a day color with associations of energy and incentive. For primitive man, activity during the day meant hunting and attacking, while he soon saw as red, the color of blood and rage and the heat that came with effort. And green is associated with passive defense and self-preservation.
Experiments have shown that colors, partly because of their physiological associations, also have a direct psychological effect. People exposed to bright red show an increase in heartbeat, and blood pressure; red is exciting. Similar exposure to pure blue has exactly the opposite effect; it is a calming color. Because of its exciting connotation(涵义), red was chosen as the signal for danger. But closer analysis shows that a vivid yellow can produce a more basic state of alertness and alarm, so fire engines and ambulances in some advanced communities are now rushing around in bright yellow colors that stop the traffic dead.

单选题Last year ______ of new books were published on human rights issues.
单选题When I was a college student, I did a lot of traveling abroad. That was because a professor
1
me to do so. She said, "Now is the time for you to travel around the world,
2
your knowledge through actual experiences and have fun!" I
3
her.
Since I started to work for a
4
company, however, I have done most of my traveling through the Internet. By using the Internet, I have seen the
5
of many cities on my computer screen. And I have really made business
6
, too. With the help of the Internet, I have also got
7
about food in different countries.
Therefore, I was beginning to feel that actual trips were
8
necessary when I happened to read a famous chef"s(厨师) comment on the Internet. He said, "It is very difficult to have real Italian food in a foreign country, because we enjoy food and the
9
around us at the same time. So why don"t you fly over to Italy and enjoy real Italian
10
?" Those words reminded me of my
11
advice. As information technology
12
, you might be able to do without making some real trips. But this also means that you will miss the various
13
you can get from traveling.
Today there are people who
14
direct communication with others and spend much of their time on the Internet. It is not surprising to see a group of people .
15
not with each other but into their micro phones. It seems as if such people are
16
by an invisible wall. They seem to be losing out on a good chance to
17
and talk with other people. I do not think that they are taking good advantage of information technology. We should use information technology as a tool to make our daily
18
more fruitful. However, we should never let it
19
our time for face-to-face communication. Let"s make use of information technology more
20
, and have great fun in experiencing the actual world.

单选题A Lucky Survivor
Niagara Falls, Ontario, Canada—A man survived a plunge(跳入) over Niagara Falls with only the clothes on his back. He was the first person known to have done it without safety equipment and live.
Witnesses described seeing the man float by on Monday in the Niagara River, go head first over the 54-metre waterfall and then pull himself out of the water onto rocks below. Water rushes over the Falls at a rate of 570000 litres per second.
"He just looked calm. He was just going past so fast. I was in shock really to see a person go by," Brenda McMullen told a TV station.
"I saw him disappear over the edge of the falls," Brenda"s husband, Terry McMullen said. The American tourists took photographs afterwards, showing the man dressed in street clothes, apparently lying on the shoreline at the base of the Canadian Horseshoe Falls.
"The guy just basically jumped in the falls," said witness Diedre Love, who was there with her husband to celebrate their first wedding anniversary(周年纪念).
Only one other person was known to survive a plunge over the Canadian falls without a barrel or other equipment. This was a seven-year-old boy wearing a life jacket who was thrown into the water in a 1960 boating accident.
No one has ever survived a trip over the narrower and rockier American falls. Police would not release the man"s name nor would they tell the press why the man went over the falls. He did not appear to have serious injuries as he was led away. He was taken to the Greater Niagara General Hospital for treatment.
单选题The foreign friends were all amazed to see ______ here in the past several years.
单选题Most young people enjoy some form of physical activity. Those who have a passion for climbing high and difficult mountains are often looked upon with astonishment. Why are men and women willing to suffer cold and hardship, and to take risks on those high mountains? This astonishment is caused probably by the difference between mountaineering and other forms of activity to which men give their leisure.
Mountaineering is a sport and not a game. There are no man-made rules, as there are for such games as golf and football. It is this freedom from man-made rules that makes mountaineering attractive to many people. Those who climb mountains are free to use their own methods.
If we compare mountaineering and other more familiar sports, we might think that one big difference is that mountaineering is not a "team game". We should be mistaken in this. There are, it is true, no "matches" between "teams" of climbers, but when climbers are on a rock linked by a rope on which their lives may depend, there is obviously teamwork.
The mountain climbers know that he may have to fight forces that are stronger and more powerful than man. He has to fight the forces of nature. This sport, hence, requires his high mental and physical qualities.
