About ten men in every hundred suffer from color blindness in some way. Women are luckier; only about one in two hundred is affected in this matter. Perhaps, after all, it is safer to be driven by a woman!
There are different forms of color blindness. In some cases a man may not be able to see deep red. He may think that red, orange and yellow are all shadows of green. Sometimes a person cannot tell the difference between blue and green. In rare cases an unlucky man may see everything in shades of green - a strange world indeed.
Color blindness in human beings is a strange thing to explain. In a single eye there are millions of very small things called “cones”. These help us to see in a bright light and to tell difference between colors. There are also millions of “rods”, but these are used for seeing when it is near dark. They show us shape but no color.
Some insects have favorite colors. Mosquitoes prefer blue to yellow. A red light will not attract insects, but a blue lamp will. In a similar way human beings also have favorite colors. Yet we are lucky. With the aid of the cones in our eyes we can see many beautiful colors by day, and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible colors around us.

American researchers found females are the more talkative sex because of a special “language protein(蛋白质)” in the brain.
The study, conducted by neuroscientists (神经学家)and psychologist from the University of Maryland, concluded that women talked more because they had more of the Foxp2 protein. The research, published in the Journal of Neuroscience, found that higher levels were found among humans that were women but in rats that were males. Their findings came after it was previously claimed that ladies speak about 20,000 words a day – over 13,000 more than men. “This study is one of the first to report a sex difference in the expression of a language-associated protein in humans or animals,” said Prof Margaret McCarthy, who led the study. In their study, the researchers attempted to determine what might make male rats more vocal than their female friends.
They separated four-day-old rats from their mothers and then counted the number of times they cried out in the “ultrasonic range”, the frequencies higher than humans can hear, over five minutes. While both sexes called out hundreds of cries, the males called out twice as often, they found. But when the pups were returned to their mother’s cage, she fussed over her sons first. Tests conducted on the parts of the brain known to be associated with vocalcalls showed the male pups have up to twice as much Foxp2 protein as the females. The researchers then increased the production in the brains of female pups and reduced it in males. This led to the female rats crying out more often and their mothers showing more interest to them. In contrast, males became less “talkative”.
The researchers then tested samples from ten children, aged between three and five, which showed that females had up to 30 per cent more of the Foxp2 protein than males, in a brain area key to language in humans.
“Based on our observations, we assume higher levels of Foxp2 in girls and higher levels of Foxp2 in male rats is an indication that Foxp2 protein levels are associated with the more communicative sex,” said Prof McCarthy. “Our results imply Foxp2 as a component of the neurobiological basis of sex differences in vocal communication in mammals. “
【小题1】From the second paragraph, we can learn that ________.
A.women always speak more words than men |
B.men and male rats have low levels of language protein |
C.women and male rats have similar levels of Foxp2 |
D.McCarthy isn’t the first to find females more talkative |

A.test which part of the brain is key to language in rats and humans |
B.prove the levels of Foxp2 protein in humans and rats are different |
C.determine the reason why female rats are more talkative than male rats |
D.discover the association between Foxp2 protein and vocal communication |
A.Tests on humans and rats |
B.Why women are the talkative sex |
C.Sex differences in Foxp2 protein |
D.Foxp2 protein determines oral ability |

There has been a large increase in the number of natural disasters over the past few years, and it is believed that global warming and climate change could cause even more disasters in thefuture. Some of the world’s leading cities are facing disasters like floods and heat waves.
London
London’s flood defences are getting older. Since 1982, the Thames Barrier(水闸)has protected the city from the threat (威胁)of flooding, but it was only designed to last until 2030 and close once every two or three years. About 31 years later the barrier now closes five or six times a year and according to Environment Agency predictions, by 2050 the barrier will be closed on almost every tide if the problem is not solved
There are 26 underground stations, 400 schools, 16 hospitals, an airport and 80 billion worth of property(财产)in London’s flood risk area, so large scale flooding would be disastrous.
Paris
Over a six week period in July and August 2003, more than 1 1,400—mainly elderly people—died in France from dehydration(脱水)and extremely high body temperature in a deadly heat wave. Heat waves of similar intensity(强度)are expected every seven years by 2050, so what can be done to make sure such a disaster does not happen again?
One solution is to have air-conditioners installed(安装)in elderly care homes. But this is considered a short-term solution, as the increase in demand for electricity also increases carbon emissions(排放).
In Paris the local authorities are encouraging architects to design new types of buildings such as the building “Flower Tower,” which uses a covering of bamboo to act as a natural air-conditioner.
Shanghai
Shanghai is the fastest growing city on Earth. It has a population of 18 million and is only 4 meters above sea level. Sea levels are predicted to rise by 20 cm within the next century.
About 250,000 people move to Shanghai every year in search of work, placing extra demands on energy consumption(消耗). China depends heavily on coal—fired power stations, but these emissions increase temperatures and, in turn, warmer seas increase the risk of typhoons.
【小题1】What problem should be settled now in London?
A.How to protect the city’s property |
B.Where to build its flood defences |
C.How to use the Thames Barrier to protect the city |
D.How to improve the function of the old flood defences |
A.Putting up new types of buildings with a covering of bamboo. |
B.Having air-conditioners installed in elderly care homes. |
C.Forbidding the city to build “Flower Tower”. |
D.Encouraging architects to design new types of buildings. |
A.increasing population and coal-fired power stations |
B.rising sea levels and typhoons |
C.extremely high temperature and rising sea levels |
D.extra demands on energy consumption and typhoons |
A.to tell us how to protect the big cities |
B.to give advice on how to defend natural disasters |
C.to explain what causes flood and heat waves |
D.to warn us of the increasing natural disasters in big cities |

Everybody knows that colors are connected with certain feelings. For example, why do some people paint the walls of their rooms yellow and others pink? The same is true in stores. They want us to feel something when we look at their products.
Green, for example, tries to show the quality of a product: how good it is for us or for our environment. It also suggests that the product is healthier, has less fat and maybe fewer calories. Red, on the other hand is an aggressive color that is often used for packaging food. Red wants us to become hungry or thirsty. Purple is a kind of color that is often seen as royal. It indicates that it is something special. Producers use purple to show that something is of good quality. Blue is not very often found in food packaging because there are not very many foods that have a blue color.
Colors can also have different meaning in different cultures and countries. For example, while the color white is used in many Western countries to represent purity and innocence, it is seen as a symbol of mourning in many Eastern countries. The Egyptian pharaohs(法老) wore white crowns. A white sale is a sale of sheets, towels, and other bed and bath items. A white flag is the universal symbol for truce(休战). A white elephant is a rare, pale elephant sacred(神圣的) to the people of India, Thailand, Burma, and Sri Lanka. In these countries, something that is a white elephant is either a possession that costs more than it is worth to keep or an item that the owner doesn’t want but can’t get rid of.
Consumers are aware that certain foods must have certain colors. When Pepsi brought out a crystal clear cola in 1992, it thought that consumers would buy it because clear meant pure and healthy. After a few months Pepsi found out that a cola had to be dark-colored. Crystal Pepsi failed and the company pulled it off the market.
Advertising professionals often need to look at a product through the consumers’ eyes when choosing a color. The right packaging colors can truly improve the sales of a product but choosing a wrong color could end in failure.
【小题1】According to the passage, blue is rarely used in food packaging because ____.
A.most consumers dislike it |
B.it matches very few foods |
C.it brings people low spirits |
D.it doesn’t catch people’s eyes |
A.a white flag | B.a white elephant |
C.a white sale | D.a white crown |
A.Pepsi’s success comes from failures |
B.health is the main concern in drink making |
C.crystal clear drinks can’t attract consumers |
D.people have fixed ideas about products and colors |
A.Colors in advertising |
B.Colors in food packaging |
C.Our everyday life and colors |
D.Foods in different colors |

Popeye the Sailor first became a popular cartoon in the 1930s.The sailor in that cartoon ate lots of spinach to make him strong. People watched him, and they began to buy and eat a lot more spinach. Popeye helped sell 33 percent more spinach than before! Spinach became a necessary part of many people’s diets. Even some children who hated the taste began to eat the vegetable.
Many people thought that the iron in spinach made Popeye strong, but this is not true. Spinach does not have any more iron than any other green vegetable.
People only thought spinach had a lot of iron because the people who studied the food made a mistake. In the 1890s, a group of people studied what was inside vegetables. This group said that spinach had ten times more iron than it did. The group wrote the number wrong, and everyone accepted it.
Today, we know that the little iron that is in spinach cannot make a difference in how strong a person is. However, spinach does have something else which the body needs—folic acid.
It is interesting to point out that folic acid can help make a person strong. Maybe it was really the folic acid that made Popeye strong all along.
【小题1】A good title for this reading passage is______.
A.Popeye the Sailor | B.The Truth About Spinach |
C.A Mistake with Numbers | D.Folic Acid Makes You Strong |
A.They thought spinach made them strong. |
B.They thought Popeye was funny. |
C.Spinach had a lot of iron. |
D.People liked folic acid. |
A.made Popeye strong |
B.was a green vegetable |
C.had less iron than other green vegetables |
D.had more iron than other green vegetables |
A.iron | B.folic acid | C.spinach | D.exercise |

Scientific experiments can sometimes go wrong and when they do the results may range from the disastrous to the troubling. One such experiment took place in South America about fifty years ago. Whether its final consequences will cause serious damage or nothing more than a small trouble still remains to be seen.
The story began in 1956 when an American scientist working in Brazil decided to solve the problem of increasing the productivity of that country’s bees. He imported a very active type of African bee from Tanzania and mated (交配)it with the more easy-going native variety to produce a new kind of bees. The new bees worked harder and produced twice as much honey. It seemed that Professor Kerr, for that was the scientist's name, had a total success on his hands.www.zxxk.com
Then things began to go wrong. For some reason as yet unseen, but perhaps as a result of something in their environment, the new bees began to develop extremely attacking personalities. They became bad-tempered and easy to be angry, attacked the native bees and drove them from their living places.
But worse was to follow. Having taken over the countryside, the new bees, with their dangerous stings (叮) , began to attack its neighbors -- cats, dogs, horses, chickens and finally man himself. A long period of terror began that has so far killed a great number of animals and about 150 human beings.
This would have been bad enough if the bees had stayed in Brazil. But now they are on the move, heading northwards in countless millions towards Central and North America, and moving at the alarming speed of 200 miles a year. The countries that lie in their path are naturally worried because it looks as if nothing can be done to stop them.
【小题1】 The results of the South American experiment .
A.are not yet certain | B.have proved to be wrong |
C.have caused a serious trouble | D.are not important |
A.make African bees less active |
B.make Brazilian bees more easy-going |
C.increase the number of bees in Brazil |
D.increase the amount of honey in Brazil |
A.Their production of honey. | B.Their living environment. |
C.Their hard work. | D.Their bad temper. |
A.the bees have been driven to Central and North America |
B.the bees must be stopped from moving north |
C.the bees may bring about trouble in more countries |
D.the bees prefer to live in Brazil |

We probably all know people, either at work or in our personal lives, who are really good listeners. No matter what kind of situation we’re in, they always seem to know just what to say and how to say it so that we’re not offended(被冒犯) or upset. We probably also know people who are masters at managing their emotions(情绪). They don’t get angry in stressful situations. Instead, they have the ability to calmly look at a problem and find a solution. They take criticism(批评) well, and they know when to use it to improve their performance.
People like these who have a high degree of emotional intelligence, or EI(情商). They know themselves very well, and they’re also able to sense the emotional needs of others.
As more and more people accept that emotional intelligence is just as important to professional success as technical(专业的) ability, companies are increasingly using EI when they hire and promote(提拔) someone. For example, one large cosmetics (化妆品) company recently changed their hiring process for salespeople to choose candidates(被选的人) based on emotional intelligence. The result? Salespeople hired with the new system have sold, on average, $91,000 more than salespeople selected under the old system.
Emotional intelligence is the ability to recognize your emotions, understand what they are telling you, and realize how your emotions affect people around you. Emotional intelligence also involves your perception (洞察力) of others: when you understand how they feel, this allows you to manage relationships more effectively.
People with high emotional intelligence are usually successful in most things they do. Why? Because they are the ones that others want on their team. When people with high EI send an email, it get answered. When they need help, they get it. Because they make others feel good, they go through life much more easily than people who are easily angered or upset.
The good news is that emotional intelligence can be taught and developed. Many books and tests are available to help you determine your current EI, and identify where you may need to do some work.
【小题1】According to the passage, we’re all probably impressed by people who _____.
A.are ready to help others |
B.are very successful in their lives |
C.have high emotional intelligence |
D.know how to control their temper |
A.stress the importance of emotional intelligence |
B.speak highly of its new salespeople |
C.show its effective hiring system |
D.explain what improvements it has made |
A.your emotions | B.people around you |

It is often said that man has become the enemy of our planet. This is no exaggeration(夸张), for reports show that man’s greed has done much to destroy the earth. Man, in his greedy desire for financial growth, has polluted the air, land and water, and has robbed our valuable natural resources. Man’s industrial plants pour out poisonous waste that pollutes the sea and puts life in the sea under the threat of dying out; at the same time, they release alarming amounts of carbon dioxide, chlorofluorocarbons (CFCs) and other pollutants. Small wonder that the air now is much warmer and more impure than ever before.
Of course, this is not just because of man’s greed—it is man’s pressing need as well. For instance, in developing countries, huge financial foreign debts have forced governments to approve the cutting of forests for agriculture or ranching. As a result, forests are cut down just to meet man’s immediate needs.
Perhaps unknowingly,man has changed the make-up of the earth's atmosphere. Scientific studies have shown that CFCs used in refrigerators and industrial cleaners are fast destroying the ozone layer—a protective layer in the atmosphere that protects us against the harmful effects of the sun’s ultraviolet (紫外线)rays. In fact, documented reports have shown a terrible fact that there are “holes” in the ozone layer over the Antarctic. And they appear to be expanding.
Faced with these environmental problems, world leaders have shown deep concern. The UN Environmental Programme (UNEP) has arranged international agreements like the Vienna convention of 1985 and the Montreal Protocol of 1989 to preserve the ozone layer by controlling the production, use and trade of destructive chemicals.
There may be some doubt as to how effectual these agreements may be, given that some countries still maintain an “I-don’t-care” attitude. Their attitude is probably due to their failure to grasp the importance of the problem. Then, there is no doubt that environmental education on an international scale(规模)is greatly needed, so that all countries, great and small—the “haves” and the “have nots”—may realize their responsibilities for our planet.
In the meantime, the UNEP seems to have taken steps in the right direction, and it is hoped that in the not so distant future, all nations of the world will join hands in saving mother earth.
【小题1】Which of the following is a reason for the cutting and burning of forests?
A.To build houses for more population. | B.To have land for agriculture. |
C.To export trees to other countries. | D.To build industrial plants. |
A.man’s research activities | B.the greenhouse effect |
C.the ultraviolent | D.harmful chemicals |
A.They don’t want to put their lives in danger. |
B.They just don’t know how to solve the problem. |
C.They haven’t realized the seriousness of the problem. |
D.They don’t want to break their international commitment. |

Babies who are slow to gain weight in the first months of their lives generally catch up to their peers by age 13,a large UK study shows, Researchers said the results would make parents whose babies fail to put on weight quickly less worried.
The researchers looked at data from ,11,499 children who took part in a large study, It showed that 507 who were slow to gain weight in the first eight weeks of life recovered fairly quickly and had almost caught up by age 2. Another group of 480 who were slow to gain between eight weeks and nine months continued to put on weight slowly until they were seven years ,but then had a sudden increase and caught up by age 13, The different pattems of recovery between the two groups were likely due to different reasons for slow weight gain ,the researchers said, All the children were still lighter and shorter than their peers by the time they were teenagers ,but within the normal range.
The findings highlight the importance of monitoring a baby’s weight and height gain during the first few weeks and months ,but not creating anxiety with parents of slow-growing babies, said the study leader Prof Alan Emond from the University of Bristol.
“In the past, a lot of parents have been caused unnecessary anxiety by heaith professionals and this is a positive and reassuring message.”He said in many cases of slow growth where children do not follow the standard’curve’(曲线)it is just because they are following their genetic potential.
Dr Simon Newell, vice-president of the Royal College of Paediatrics and Child Health, said he broadly agreed with the concluslons of the researchers but stressed that poor weight gain was something that needed to be monitored closely, “I would encourage parents to use growth charts but if measurements show your baby is smaller than averager it may be completely normal, ”he said.
【小题1】What can we know from the findings of the research?
A.All the cases of slow weight gain in the first months of the babies’ lives are caused by the same reason |
B.Slow-growing babies will have the same height and weight with their peers by age13 |
C.Many cases of children whose growth don’t meet the growing standard curve cannot be treated as abnormal |
D.The findings won’t cause parents’ anxiety so monitoring a baby’s growth from his/her birth is unnecessary |
A.It’s important to monitor a baby’s weight and height gain for new parents |
B.New parents should feel anxious about their baby’s weight and height gain |
C.Researches still couldn’t find the reasons for slow weight gain |
D.All the children’s weight and height became normal by age 13 |
A.Making sure something is certain to be true |
B.Making someone calmer and less anxious |
C.Confirming something is to happen again |
D.Being sure that someone can be attracted |
A.To some degree, growth charts can help parents monitor their babies’ weight gain |
B.It’s abnormal for babies are smaller than average |
C.He agreed with the researchers completely |
D.Babies’ weight gain can only be monitored and measured by using growth charts. |
A.tell us how to help babies grow faster |
B.explain why babies are gain weight slowly |
