Scientists are developing a new kind of machine to take the place of humans. These machines can do jobs in places that are too dangerous for humans. For example, they are being developed to work in nuclear power center, deep under the oceans and in outer space.
John Marrit, a psychologist(心理学家) in Williamsburg Massachusetts, helped develop the new machine. This is how they work. A machine is placed in an area far away from the person who operates it. The person wears special hard hat with television screens and sound equipment. The screens and sound equipment let the person see and hear exactly what the machine is seeing and hearing. Mr. Marrit says this gives the person the feeling of being in the same place as the machine. The idea, he says, is being there without going there. The person uses an electronic control to make the machine move. The machine copies the person’s movements exactly. If the person raises his right arm, the machine raises the right arm, too. This means an expert can do a dangerous job while staying in the safe place. For example, a person can direct the machine to destroy a bomb without going near the bomb himself.
【小题1】The new kind of machine being introduced in the passage is _______.
| A．in existence | B．only an idea |
| C．being tried out | D．being researched and developed |
| A．follows the person’s order |
| B．is controlled by a computer |
| C．does exactly what the person does |
| D．is controlled by a television on the person’s head |
| A．the new machine is more difficult to make than a robot |
| B．the new machine is more difficult to be controlled |
| C．a robot is controlled by man indirectly |
| D．a robot can’t be used in places too dangerous or faraway |
【小题1】D
【小题2】C
【小题3】A
解析试题分析：科学家正在开发一种代替人的机器，这种机器能代替人们从事一些危险 的工作。
【小题1】判断题。 从第 1 句话 Scientists are developing a new kind of machine to take the place of humans 可以看出，既然是正在开发当中，那肯定还未形成。选D
【小题2】语义理解题。从第 2 段中The machine copies the person’s movements exactly 可以看出机器人做的是人类做的事情， 明显看出为什么选 C 的原因。A 项有一定的干扰性，但这种机器是人通过电控开关控制的， 所以应排除。选C
【小题3】判断题。这种机器还在开发当中，而机器人则有几十年历史了，可知这种机器人更加难制作，由此可以肯定答案应该选 A。

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 can not see deep red. He may think that red, orange and yellow are all shades 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 nearly dark. They show us shape but no color.
Some insects have favorite colors. Mosquitoes (蚊子) like blue but do not like 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 (看不见的) colors around.
【小题1】Why do some people say it is safer to be driven by women?
| A．Women are more careful. |
| B．There are few color-blind women. |
| C．Women are fonder of driving than men. |
| D．Women are weaker but quicker in thinking |
| A．color and its surprising effects |
| B．women being luckier than men |
| C．danger caused by color blindness |
| D．color blindness |
| A．tell orange from yellow |
| B．see in weak light |
| C．kill mosquitoes |
| D．tell different shapes |
| A．red light | B．yellow light | C．blue light | D．green light |

The United States is full of cars. There are still many families without cars, but some families have two or more. However, cars are used for more than pleasure. They are a necessary part of life.
Cars are used for business. They are driven to offices and factories by workers who have no other way to get to their jobs. When salesmen are sent to different parts of the city, they have to drive in order to carry their products. Farmers have to drive into the city in order to get supplies.
Sometimes small children must be driven to school. In some cities school buses are used only when children live more than a mile away from the school. When the children are too young to walk too far, their mothers take turns driving them to school. One mother drives on Mondays taking her own children and the neighbors' as well. Another mother drives on Tuesdays, another on Wednesday, and so on. This is called forming a car pool. Men also form car pools, with three or four men taking turns driving to the place where they all work.
More car pools should be formed in order to put fewer cars on the road and use less gas. Too many cars are being driven. Something will have to be done about the use of cars.
【小题1】The United States is filled with cars, but .
| A．not every family has a car |

Bissel is a small village of the West Sahara. It lies next to a l.5-square-kilometer oasis（绿洲）, from where three days and nights are generally required to go out of the desert. However, before Ken Levin discovered it in 1926, none of the Bissel villagers had ever walked out of the desert. Reportedly, they were not unwilling to leave this barren land. Many had previously tried but failed, always somehow finding themselves back at the oasis after several days of trying to walk out.
When interviewed by Ken Levin, an expert at the British Royal College of Sciences, the villagers explained that no matter which direction they walked it always brought them back to the village.Why couldn’t the Bissel villagers walk out of the desert? Levin was very puzzled. He had, by himself, managed to walk north from the village and reach the nearest town in three and a half days. He decided to carry out an experiment to solve the mystery. He and a Bissel villager called Argutel, would walk out of the desert together. They prepared enough water for a half-a-month journey and two camels. But this time Ken Levin didn't bring his compass. Levin would follow Argutel.
Ten days later, they had walked for about 500 miles but were still in the desert. On the 11th morning, an oasis came into their view. They were back at Bissel. Levin now understood why the Bissel people couldn’t escape the desert. They had no knowledge of the North Star, which had for centuries provided sailors and other travelers with a point of direction. In the desert, if a person goes forward relying only on their senses, they will not be able to travel in a straight line. Rather they will travel in a very large circle and eventually track back to where they began. Levin explained to Argutel the function of the North Star and said, “As long as you rest in the daytime and walk towards the brightest star at night, you would be able to walk out of the desert.” Argutel did as he was told. Three days later, he came to the edge of the desert.
Now in the West Sahara, Bissel has become a bright pearl, where tens of thousands of tourists come every year. Argutel’s bronze statue stands in the center of the town. On its base are the words: __________________________.
【小题1】Ken Levin asked Argutel to walk to the north in order to ________.
| A．prove that people could walk out of the desert see |
| B．how far away Bissel was to the edge of the desert |
| C．tell people not to walk in circles |
| D．show Argutel was a great person |
| A．knew Argutel before he came to the village |
| B．came to Bissel to do experiments on behalf of his college |
| C．became the first man to walk out of the desert from Bissel Village |
| D．taught Bissel villagers knowledge of the North Star when he first arrived |
| A．Ken Levin didn’t walk south because it would take more days |
| B．the use of a compass was necessary to walk out of the desert |
| C．tourism in Bissel has been greatly developed and improved |
| D．Argutel became the leader of Bissel after his return |
| A．A new life starts from the fixed direction. |
| B．Where there is a will , there is a way . |
| C．A long journey starts with the first step . |

The smallest animal with a backbone（脊椎） known to science, a fish from the carp family, has been discovered in the peat swamps （沼泽）of Indonesia. Mature（成熟的）females of the fish species （种类）Paedocypris reach just 7.9mm in length.
The species was discovered in the highly acidic (酸性的) peat swamps of the Indonesian island of Sumatra by a team led by Ralf Britz, a zoologist at the Natural History Museum in London.
“This is one of the strangest fish that I’ve seen in my whole career,” Dr Britz said. “It’s tiny, and it lives in acid. I hope that we’ll have time to find out more about them before their habitat disappears completely.”
The species lives in dark tea-colored swamp waters, which are 100 times more acidic than rainwater. Although these swamps were once thought to be inhabited by very few animals, recent research has shown that they are home to a highly different range of species that occur nowhere else.
The peat swamps were damaged by forest fires in 1997, and are also threatened by agriculture. The scientists behind the discovery said that several populations of Paedocypris had already been lost.
“Many of the peat swamps we surveyed（调查）throughout South-East Asia no longer exist,” Dr Britz said. “Populations of all the miniature（微型的）fish of peat swamps have decreased or disappeared.”
Details of the discovery are published today in the journal Proceedings of the Royal Society of London, Series B.
【小题1】64.Which of the following would be the best title for the passage?
| A．The Strangest Fish |
| B．Acidic Peat Swamps |
| C．Strange Species |
| D．The Smallest Backbone Animal |
| A．It lives in highly acidic rainwater. |
| B．The species lives in the acidic waters of dark tea-coloured swamps. |
| C．It was put in the Natural History Museum in London. |
| D．Its habitat disappears completely. |
| A．many places where these animals lived have been damaged |
| B．the population of the specieshas increased |
| C．there are many animals in the acidic peat swamps today |
| D．agriculture doesn’t affect the living space of these animals |
| A．the habitat will be more after a period of time |

Unknown to most Facebook users, the social network actually offers a lot of privacy controls and security features which can help you lock your account, so you can speak freely. If it’s used properly, you’ll never have to worry about whether you will have to “friend” your boss or your mom. You can friend anyone you want while staying comfortable in the knowledge that not everyone gets to see everything you post.
The problem with carrying out these privacy options is that they’re just too confusing for most non-tech clever people to handle. And often, most people don’t want to bother to take the time to learn. To simplify the process, we’re offering one easy step you can take today to help make your Facebook experience safer, more secure, and more private.
Just make “Friend Lists”. Yes, it will take some time, especially if you’re connected to a couple of hundred friends already. But this step, while not the quickest, is fairly simple. And it will be one of the most useful things you can do on Facebook.
Friend lists, as the name suggests, are lists for classifying your friends into various groups. The nice thing about this feature is that once you set these lists up, you won’t have to do it again. We suggest that you put your work colleagues and professional acquaintances into a friend list named “Work”, personal friends you’re not very close with into a list called “Acquaintances”, and people you’re related to into a list called “Family”. Those three main categories will separate out the groups of “friends” who you may want to hide some information from.
To create a friend list, click on “Friends” at the top of the Facebook homepage. In the left-hand column, click “Friends” again under the “Lists” section. Now you’ll see a button at the top that says “Create New List”. Click it. In the pop-up that appears, you can name your list and pick members. If you’ve ever shared an application with your friends, the process of doing this will be very familiar.
When you’ve finished making lists, you’ll be able to use them when selecting who can see what (or who can’t!) when configuring (配置) the security settings described below.
【小题1】What function isn’t understood by most people on Facebook?
| A．Surfing the Internet. |
| B．Setting safety protection. |
| C．Sharing personal information. |
| D．Making foreign friends. |
| A．Its process of privacy-setting is too complex. |
| B．It displays everything people post. |
| C．It lacks privacy controls and security features. |
| D．Its post is designed for technical people. |
| A．We can avoid our bosses adding us as friends. |
| B．We can share applications with friends. |
| C．We can separate acquaintances from family. |
| D．We can hide different information from different friends. |

How long you live has a lot to do with your environment and lifestyle, but exceptional(特别的)long life may have even more to do with your genes. For the first time, researchers have discovered a genetic recipe(基因谱)that accurately predicts who may live to 100 and beyond.
Analysis shows that 90% of the participants who lived to 100 had at least one of the signature genetic clusters(标志基因组). Dr. Thomas Perls at the Boston University School of Medicine said, “We realize this is a complex genetic puzzle. There is a long way for us to go to understand how the integration(融合)of these genes—not just with themselves but with environmental factors—is playing a role in this long life puzzle.”
Perls has studied many factors that contribute to long life, and he is the first to acknowledge that living longer isn’t likely to be simply a matter of genes. His previous work has shown, for example, that among most elderly people who live into their 70s and 80s, about 70% can owe their long life to environmental factors such as not smoking; eating a healthy, low-fat, low-calorie diet; and remaining socially engaged and mentally active throughout life.
It seems clear that those who live extremely long are benefiting from a special DNA. In fact, Perls believes that the older a person gets, the more likely it is that his or her genes are contributing to those extended years.
【小题1】Which of the following is TRUE according to Paragraph 2?
| A．Most long-living people have special long-life-related genes. |
| B．Ninety percent of the participants lived to 100 years of age. |
| C．All the long-living people have only one signature genetic cluster. |
| D．Scientists know how the integration of the genes helps people live long. |
| A．most people living extremely long benefit from not smoking |
| B．living longer just depends on certain genetic recipes |
| C．environmental factors play an important role in long-living |
| D．being mentally active has nothing to do with living an old age |
| A．Remaining socially engaged helps a person to live long. |
| B．A genetic recipe can accurately predict who may live to 100 and beyond. |
| C．Perls is the first to think living longer is just a matter of genes. |
| D．The older he gets, the more likely the genes contribute to his extended years. |
| A．Genes May Predict Who Lives to 100 | B．Environment And Genes |
| C．Genes, the Secret of Long Living | D．Lifestyle And Genes |

New research shows that overweight or even mildly obese people have a lower risk of early death than people considered to be normal weight.
Researchers examined the results of 97 studies. Most of the studies were less than 10 years old. They included almost three million adults from around the world, including the United States, Canada, China, Taiwan, Brazil, India and Mexico.
The researchers at the National Center for Health Statistics found that people who are considered overweight or slightly obese were five to six percent less likely to die from all causes than people of normal weight. People with higher obesity ratings, however, had almost a 30 percent greater risk of death compared to normal-weight individuals.
Katherine Flegal was the lead author of the study. She says she was not surprised that overweight people would not have a higher risk of death.
“Because we’d actually already read a lot of this literature and realized it was likely that mortality rates (死亡率) for overweight would be at least not higher than normal weight. I guess I was a little bit surprised that it was definitely lower. And I was also surprised that the lower rates of obesity also didn’t seem to differ from normal weight.”
But she says the difference in death rates appears to be small between normal-weight people and those who are overweight or mildly obese.
The study has raised new questions about “body mass index,”（体重指数） or BMI. This is a measurement of body fat as a ratio（比率） of height to weight. In recent years, many public health experts have promoted body mass index as a way to predict the risk of health problems. Bu t a person's BMI can be misleading in some cases.
Steven Heymsfield ,the executive director of the Pennington Biomedical Research Center, says people can be physically fit and in good health, but might weigh more because they are more muscular.
Still, Dr. Heymsfield says people should not think gaining extra weight is OK just because of the new findings. He says being at a healthy weight lowers the risk for heart disease and diabetes（糖尿病）.
【小题1】According to the new findings, the researchers found that __________ .
| A．People with high obesity have a lower risk of early death than people with low obesity |
| B．People with overweight have a greater risk of early death than people of normal weight. |
| C．People with mild obesity are less likely to die than people of normal weight. |
| D．People with obesity live much longer than people of normal weight. |
| A．works like novels and poems |
| B．books and articles on a particular subject |
| C．printed material |
| D．magazines and newspapers |
| A．BMI is commonly used to measure body fat as a ratio of height to weight. |
| B．Not all people with a little higher BMI are fat . |
| C．Many public health experts encourage more people to use BMI as a way to predict the risk of health problem |
| D．Because of the ne w findings, people should think about gaining extra weight. |

What will people die of 100 years from now? If you think that is a simple question, you have not been paying attention to the revolution that is taking place in bio-technology(生物技术). With the help of new medicine, the human body will last a very long time. Death will come mainly from accidents, murder and war. Today's leading killers, such as heart diseases, cancer, and aging itself, will become distant memory.
In discussion of technological changes, the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live? Human brains were known to decide the final death. Cells(细胞) are the basic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cells, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine to repair their organs(器官). The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on---in much the same way our bodies make new skin cells to take the place of old ones.
It is exciting to imagine that the advance in technology may be changing the most basic conditional human existence, but many technical problems still must be cleared up on the way to this wonderful future.
【小题1】According to the passage, human death is now mainly caused by _______.
| A．diseases and aging | B．accidents and war |
| C．accidents and aging | D．heart diseases and war |
| A．medicine | B．the internet |
| C．brain cells | D．human organs |
| A．heart disease will be far away from us |
| B．human brains can decide the final death |
| C．the basic materials of cells will last forever |
| D．human organs can be repaired by new medicine |
| A．human life will not last more than 120 years in the future |
| B．human have to take medicine to build new skin cells now |
| C．much needs to be done before humans can have a longer life |
| D．we have already solved the technical problems in building new cells. |
