Did you know that there are actually people who have paid for a flight to the moon? In the future, there will be a lot more opportunities to travel to faraway places than now… perhaps even as far as the moon. As people adventure further and further away and as planes, trains, cars, and rocket ships become faster, is it safer to have these vehicles controlled by humans or by computers?
While many flights by plane are controlled automatically by machines, most people today wouldn’t let their car drive itself. That’s because currently the autopilot function on your car can only keep it on the same course you are travelling on. It won’t turn the car right or left. It won’t stop if an animal jumps in the way. However, cars today can sense when something is too close and warn the driver with flashing lights and alarms. Many cars also have GPS(global positioning systems) that tell drivers which road to take and when to turn. These systems, unlike human drivers, never get lost. In the future, it is easy to believe that your car will be better able to drive itself with the aid of computers that can determine the position of your car and the speed it should travel at.
In addition to computers being ‘smarter’ than people regarding the best way to go or knowing how close another vehicle is, computers don’t get sick, tired, or angry. This means they won’t make the same mistakes that people make when they are not having a good day. While responding with emotion is a good thing when choosing the best way to deal with a friend’s personal problem, it may not be such a good thing when deciding what to do at the wheel of a fast-moving vehicle.
So what are the disadvantages of autopilot systems? Maybe one disadvantage is that a small computer problem could cause a serious accident. It could also be argued that in unexpected situations, computers might not be able to respond appropriately; some decisions require human emotions. Another problem might be that if everything were controlled by computers or robots, people wouldn’t have any jobs.

Passenger pigeons(旅鸽)once flew over much of the United States in unbelievable numbers. Written accounts from the 18th and 19th centuries described flocks(群)so large that they darkened the sky for hours.
It was calculated that when its population reach its highest point, there were more than 3 billion passenger pigeons – a number equal to 24 to 40 percent of the total bird population in the United States, making it perhaps the most abundant birds in the world. Even as late as 1870 when their numbers had already become smaller, a flock believed to be 1 mile wide and 320 miles (about 515 kilometers) long was seen near Cincinnati.
Sadly, the abundance of passenger pigeons may have been their undoing. Where the birds were abundant, people believed there was an ever-lasting supply and killed them by the thousands. Commercial hunters attracted them to small clearings with grain, waited until pigeons had settled to feed, then threw large nets over them, taking hundreds at a time. The birds were shipped to large cities and sold in restaurants.
By the closing decades of the 19th century, the hardwood forests where passenger pigeons nested had been damaged by Americans’ need for wood, which scattered(驱散)the flocks and forced the birds to go farther north, where cold temperatures and spring storms contributed to their decline. Soon the great flocks were gone, never to be seen again.
In 1897, the state of Michigan passed a law prohibiting the killing of passenger pigeons, but by then, no sizable flocks had been seen in the state for 10 years. The last confirmed wild pigeon in the United States was shot by a boy in Pike County, Ohio, in 1900. For a time, a few birds survived under human care. The last of them, known affectionately as Martha, died at the Cincinnati Zoological Garden in September 1, 1914.
【小题1】In the 18th and early 19th centuries, passenger pigeons _______.
A.were the biggest bird in the world |
B.lived mainly in the south of America |
C.did great harm to the natural environment |
D.Were the largest population in the US |
A.escape | B.ruin | C.liberation | D.evolution |
A.To seek pleasure. | B.To save other birds. |
C.To make money. | D.To protect crops. |
A.It was ignored by the public. | B.It was declared too late. |

In the future your automobile will run on water instead of gas! You will be able to buy a supercomputer that fits in your pocket! You might even drive a flying car!
For each prediction that has come true today, several others have missed by a mile. Many of these predictions didn’t consider how people would want to use the technology, or whether people really needed it in their lives or not. Let’s look at some predictions from the not-too-distant past.
Robot Helpers
Where’s the robot in my kitchen? Nowhere, of course. And he’s probably not coming anytime soon. Robots do exist today, but mostly in factories and other manufacturing environments.
Back in the 1950s, however, people said that by now personal robots would be in most people’s homes.
So why hasn’t it happened? Probably because robots are still too expensive and clumsy. And maybe the idea of robots cooking our dinners and washing our clothes is just too weird. At home we seem to be doing fine without them.
Telephones of Tomorrow
In 1964 an American company introduced the video telephone. They said by the year 2000 most people would have a video phone in their homes. But of course the idea hasn’t caught on yet.
Why? The technology worked fine, but it over-looked something obvious: people’s desire for privacy. Would you want to have a video phone conversation with someone after you just step out of the shower? Probably not—it could be embarrassing! Just because a technology available doesn’t always mean people will want to use it.
And finally, how about that crazy prediction of the flying car? It’s not so crazy anymore! But a flying car remains one of the most fascinating technology ideas to capture our imagination. Keep watching the news, or perhaps the sky outside your window, to see what the future will bring.
【小题1】The whole passage is mainly about .
A.predictions that have come true |
B.predictions that haven’t come true |
C.why predictions don’t come true easily |
D.what technology will bring about |
A.predictions needn’t consider people’s practical use of technology |
B.the future isn’t always easy to guess |
C.not all past predictions have come true |
D.many of the high-tech things our parents thought we’d be using by now simply never appeared |
A.wonderful | B.stupid |
C.practical | D.strange |
A.It is too difficult to imagine. |
B.It is too crazy an idea. |
C.It is likely to be made. |
D.It is often reported in the news. |

Ten years ago, with only about 1, 000 pandas left in the world, China was desperately trying to clone(克隆)the animal and save the endangered species(物种). That was a move similar to what Texas A & M University researchers had been undertaking for the past five years in a project called “Noah’s Ark”(诺亚方舟).
Noah’s Ark was aimed at collecting eggs, embryos(胚胎), semen and DNA of endangered animals and storing them in liquid nitrogen. If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A & M’s College of Veterinary Medicine, said there would be enough of the basic building blocks to reintroduce the species in the future.
It was estimated that as many as 2, 000 species of mammals, birds reptiles would become extinct in over 100 years. The panda, native only to China, was in danger of becoming extinct in the next 25 years.
This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They were then trying to implant the embryo into a host animal.
The entire procedure could take from three to five years to complete.
“The nucleus transfer(核子移植)of one species to another is not easy, and the lack of available(capable of being used)panda eggs could be a major problem,”Kraemer believed. “They will probably have to do several hundred transfers to result in one pregnancy(having a baby). It takes a long time and it’s difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort, ”added Kraemer, who was one of the leaders of the project at Texas A& M, the first-ever attempt at cloning a dog.
“They are trying to do something that’s never been done, and this is very similar to our work in Noah’s Ark. We’re both trying to save animals that face extinction. I certainly appreciate their effort and there’s a lot we can learn from what they are attempting to do. It’s a research that is very much needed. ”
At present, the project has worked. The number of the pandas has increased to more than 1, 500.
【小题1】The aim of “Noah’s Ark” project was to .
A.make efforts to clone the endangered pandas |
B.save endangered animals from dying out |
C.collect DNA of endangered animals to study |
D.transfer the nucleus of one animal to another |
A.available panda eggs | B.host animals |
C.qualified researchers | D.enough money |
A.China’s Success in Pandas Cloning |
B.The First Cloned Panda in the World |
C.Exploring the Possibility to Clone Pandas |
D.China—the Native Place of Pandas Forever |
A.Kraemer and his team had succeeded in cloning a dog |
B.scientists tried to implant a panda’s egg into a rabbit |
C.Kraemer would work with Chinese scientists in clone researches |

Eating different colored foods can keep you healthy, as well as change your mood and behavior. Here is a list of colors, which can change your life.
Blue/Purple
Blue is considered to be peaceful and calming and it has the same effect on our health. The blue / purple color in food is due primarily to their anthocyanins which are antioxidants (抗氧化剂) that are particularly heart healthy and may help support healthy blood pressure. Out of all the blue and purple foods available, blueberries are considered to have the highest antioxidant level. An analysis of the latest data from the National Health and Nutrition Examination Study found that people who eat purple and blue fruits and vegetables are at a reduced risk for high blood pressure and are less likely to be overweight.
A food and health expert says that blue and purple color foods can prevent blood mass formation, and they also lower the risk of cancer.
Foods that contain blue and purple colors are: reddish eggplant (especially the skin), blueberries, blackberries, purple grapes, etc.
Green
We all know that we should eat green as green symbolizes nature. The green foods are rich in isothiocyanates, which help resist cancer.
Dr. Ashok Agarwal, a food and nutrition specialist, explains, "They are excellent sources of folic acid, vitamin K, as well as carotene (胡萝卜素). Diets high in those above are associated with lowered blood pressure."
Foods that contain the green color are: broccoli, cabbage, cucumbers, etc.
Red
Lycopene (番茄红素) in reddish fruits and vegetables is a powerful antioxidant that has been associated with a reduced risk of some cancers, and also provides protection against heart attacks.
Dr. Smiths says, "Cooked tomato sauces are associated with greater health benefits as compared with the uncooked version as the heating process allows lycopene to be more easily absorbed by the body. Obtaining the most benefit from food depends on proper selection, storage and cooking of the produce."
Foods that contain red color are: Tomatoes and tomato products, watermelon, guava, red onions, red chili, red apples, red grapes, cherries, etc.
Orange
The orange foods are also rich in carotene, which are particularly good antioxidants. These foods are commonly considered eyesight foods because they contain vitamin A.
"Orange fruits and vegetables also play a part in preventing cancer, particularly of the lungs and stomach. Foods that contain the color orange are: Carrots, mangoes, sweet potatoes, pumpkins, etc.

Julie was preparing for a trip when her phone slipped into a sink full of water. Panic moment! She quickly picked up the wet phone and tried to turn it on, but nothing worked. Her first reaction? She got dressed, drove to the nearest store, and bought a new model at full price.
A new study finds that fear of losing your phone is a common illness. About 66 percent of those surveyed suffer from nomophobia or “no mobile phone phobia”. Interestingly, more women worry about losing their phone than men.
Fortunately, there’s a solution.
The first step is to figure out if you have nomophobia. Checking your phone too often is one thing, but the true sign of a problem is that you can’t conduct business or go about your routine when the fear becomes so severe.
Do you go to unusual lengths to make sure you have your phone? That’s another sign of a problem. If you find you check your phone plenty of times per hour, or a total of an hour per day, there may be a problem.
Some of the treatments are similar to those for treating anxiety attacks: Leaving the phone behind and not checking e-mail or text messages, and then learning to tolerate the after anxiety. Even if this leads to a high level of worry and stress, the solution is to push through the fear and learn to deal with not having your phone.
Of course, there are also technological alternatives. Luis Levy, a co-founder at Novy PR, says he uses an application called Cerberus that can automatically track the location of his phone. To find it, he can just go to a Web site and see the phone’s location.
He also insures his phone through a service called Asurion. The company’s description of its product reads like a prescription for anxiety: “60 million phones are lost, stolen or damaged each year. You’ll have complete peace of mind knowing that your phone is protected and you can quickly reconnect with family, friends and work, as soon as the very next day!”
【小题1】Why does the author mention Julie’s experience in the first paragraph?
A.To inform us that mobile phones are useful. |
B.To introduce the topic for discussion. |
C.To warn us that we should be careful. |
D.To tell us we should get phones ready for a trip. |
A.Fear of losing mobile phones |
B.Habits of using mobile phones |
C.Eagerness for new mobile phones |
D.Independence of mobile phones |
A.Avoiding using phone for some time |
B.Learning more about modern technology. |
C.Protecting one’s phone against any damage. |
D.Not using a mobile phone in one’s daily work. |
A.It lets you know other people also lose their phones. |
B.It will give you a new phone through insurance. |
C.It enables you to reconnect with your acquaintance. |
D.It gives you a prescription to treat nomophobia. |
A.Solutions to nomophobia. |
B.New mobile phone technology. |
C.Disadvantages of mobile phone. |
D.Attitude toward mobile phone. |

Rising levels of carbon dioxide in the atmosphere are a major cause of climate change, and now a new study has confirmed that atmosphere CO2 is also affecting the ocean chemistry and potentially harming sea life.
Montana State University scientist Robert Dore has been researching the water in the Pacific Ocean for almost two decades. “We’ve been going to the same spot in the Pacific Ocean, and we try and characterize long-term change in the open ocean environment. And one of the key things that we measure is CO2 levels. And we’ve been able to record this increasing quantity of atmosphere CO2 into the ocean.”
Scientists expected that as atmosphere CO2 increased, more and more of the carbon dioxide would be absorbed into the ocean, affecting the chemical balance of the sea water, with a potentially harmful impact on shellfish and coral in particular.
“As carbon dioxide dissolves in the water or seawater in this case, it forms a weak acid, carbonic acid,” Dore explains. “And therefore, as the concentration of CO2 in the atmosphere goes up and that exchanges with the surface seawater, it drives the pH down, and makes it more acidic.”
The seawater samples Dore and his colleagues have analyzed confirm what the theory predicts.
The effect was particular striking at about 250 meters down, and again at 500 meters. Dore and his colleagues came up with two possible explanations. It could be that surface water picked up CO2 and then moved to those depths. Or there could be a biological explanation.
“It’s important to realize that the oceans are really becoming acidic. And it can have negative impacts on a whole variety of sea life from fish to coral. It’s potentially catastrophic.”
【小题1】What can be the best title of the passage?
A.Scientist Researching Seawater |

Why is pink or purple a color for girls and blue or brown for boys?
The answer depends largely on cultural values as well as personal experiences. To the Egyptians, green was a color that represented the hope and joy of spring, while for Muslims, it means heaven. Red is a symbol of good luck in many cultures. In China, children are given money in a red envelope to bring good fortune in the New Year. For many nations, blue is a symbol of protection and religious beliefs. Greek people often wear a blue necklace hoping to protect themselves against evils(灾祸).
People’s choice of colors is also influenced by their bodies’ reactions (反应)toward them. Green is said to be the most restful color. It has the ability to reduce pain and relax people both mentally and physically. People who work in green environment have been found to have fewer stomach aches.
Red can cause a person’s blood pressure to rise and increase people’s appetites(食欲). Many decorators will include different shades of red in the restaurant. Similarly, many commercial websites will have a red “Buy Now” button because red is a color that easily catches a person’s eye.
Blue is another calming color. Unlike red, blue can cause people to lose appetite. So if you want to eat less, some suggest that eating from blue plates can help.
The next time you are deciding on what to wear or what color to decorate your room, think about the color carefully.
【小题1】Muslims regard green as a symbol of heaven mainly because of their .
A.cultural values |

Along the river banks of the Amazon and the Orinoco there lives a bird that swims before it can fly, flies like a fat chicken, eats green leaves, has the stomach of a cow and has claws(爪)on its wings when young .They build their homes about 4.6m above the river ,an important feature(特征)for the safety of the young. It is called the hoatzin.
In appearance,the birds of both sexes look very much alike with brown on the back and cream and red on the underside .The head is small, with a large set of feathers on the top, bright red eyes, and blue skin. Its nearest relatives are the common birds, cuckoos. Its most striking feature, though, is only found in the young.
Baby hoatzins have a claw on the leading edge of each wing and another at the end of each wing tip .Using these four claws ,together with the beak(喙),they can climb about in the bushes, looking very much like primitive birds must have done. When the young hoatzins have learned to fly, they lose their claws.
During the drier months between December and March hoatzins fly about the forest in groups of 20 to 30 birds, but in April, when the rainy season begins, they collect together in smaller living units of two to seven birds for producing purposes.
