Scientists have created a “ human-like robot” that can dance and do the housework.
“ Mahru” has been developed to imitate humans and can move its lips, eyebrows and pupils(瞳孔). The machine can also move its upper and lower body freely and automatically stop itself when walking.
In addition, it has been programmed to give out two kinds of pleasant smells to match its emotions.
The 1.5 tall robot was produced by researchers at the Korea Institute of Science and Technology (KIST) and is the first South Korean- developed machine of its kind.
“‘Mahru’ will open the way for the commercial use of humanoid robots doing housework,” You Bum-Jae, leader of the development research team ,said. “‘Mahru’ can dance while walking on its legs and is able to work in place of a human.”
Through an advanced motion capture (捕獲) system, “Mahru” can follow a variety of human movements and move its hands freely enough to deal with any obstacles that may get in its way when walking.
State-funded KIST showed the robot during a presentation at its head office in Seoul.
People here were treated to an entertaining demonstration which saw the robot show off the full range of its skills, most notably s series of dance moves.
The research team added that they had designed another “ Mahru”, this time with sensors(傳感器) allowing it to distinguish(分辨) between faces and objects.
The showing of “ Mahru” came a week after researcher in Japan said they had created the “most human-like” robot in the world. A team at robotics department of Osaka University in Japan claimed that “ robogirl”, Repliee R-1, “ looks, moves and interacts (相互作用) like a human, and has silicone(硅膠) skin that feels almost human to the touch.”
小題1: “Mahru” made by KIST can do the following things EXCEPT____________
A．dance with other human –like robotsB．move its body freely
C．stop automatically when walkingD．express certain feelings through smells
小題2: According to what You Bum- Jae said in Paragraph 5, his research team wants to ________.

If you have ever experienced jet lag(飛行時(shí)差反應(yīng))，you know how much of a drag it can be. Jet lag happens as a result of air travel, when traveling between two or more time zones. Your body is used to operating in a certain time zone, and when its timing is affected, you’re likely to have problems.
Edward Norton’s character in the movies Fight Club faces the struggle of jet-lag-induced sleeplessness due to his constant traveling. Sleeplessness is just one of the effects of jet lag, and it can lead to other problems, such as tiredness, memory loss and confusion. That’s not something you should have to fight on a business trip and it certainly won’t make your vacation very enjoyable, either.
Sleeplessness is the biggest problem for travelers that suffer from jet lag. Don’t worry. You can do something to prevent it.
Modify(改變)Your Body Clock
To prevent the effects on your body’s timing that come with crossing time zones, you need to change your body clock sooner, rather than later. You can do this by putting yourself on the same time as your destination time zone before you fly. If you know that you will be traveling to London from the eastern United States, you’ll have a five-hour time difference to deal with. Plan for it.
Avoid Heavy Food and Alcohol(酒精)
Part of the pleasure of flying commercially, especially if you fly business or first class, is taking advantages of the food and drinks. If you want to avoid jet lag, though, you should think twice. Eating heavy food will only make the jet lag worse. It isn’t good to drink alcohol during a flight, either, because it may make you drowsy. Wait until your body adjusts(調(diào)整) before you decide to have heavy food or drink alcohol.
小題1:
What is the main idea of the passage?
A．What jet lag is and the effects it has.
B．What jet lag is and the movies about it.
C．How jet lag happens and how to fight it.
D．How jet lag happens and tips on traveling safely.
小題2:
Norton’s character in Fight Club has to fight with         .
A．confusionB．sleeplessness
C．heavy drinkingD．memory loss
小題3:
The underlined word “drowsy” probably means “     ”.
A．worriedB．shockedC．sleepyD．excited
小題4:
According to the passage, in order to prevent jet lag, you should         .
A．sleep for the whole flightB．drink little alcohol
C．not fly business classD．know your destination well
小題5:
The passage is most likely taken from         .
A．a(chǎn) travel magazineB．a(chǎn)n entertainment report
C．a(chǎn) geography magazineD．a(chǎn) fashion website

51---------
Successful people are nicer to those who are jealous of them, psychologists have found.
　　　The fear that they may become the target of malicious（惡意的）envy makes people act more helpfully toward people who they think might be jealous of them.
　　　Previous research found jealousy could be divided into benign and malicious envy. Those with benign envy were motivated to improve themselves, to do better so they could be more like the person they envied.52--------　The Dutch researchers then set out to question the effect on the target of the envy.
In lab experiments a group of people were made to feel like they would be maliciously envied by being told they would receive an award of five euros（歐元）53-------The researchers thought that the deserved prize would lead to benign envy, while the undeserved prize would lead to malicious envy.
　　　Then the volunteer was asked to give time-consuming advice to a potentially envious person.People who had reason to think they would be the target of malicious envy were more likely to take the time to give advice than targets of benign envy.
　　　In another experiment, an experimenter dropped a number of erasers on the floor as the volunteer was leaving.54--------　He said: 'This sort of serves a useful group function. We all think better-off people should share with others but that's not something we are inclined to do when we are better off..55----------　　
A．Those who thought they would be maliciously envied were more likely to help him pick them up.
B．Helping others is a virtue.
C．However those with malicious envy wanted tobringthe more successful persondown.
D．Malicious envy. is terrible.
E. This fear of envy can encourage us to behave in ways that improve the social interactions of the group.'
　　F. People are more likely to help others if they think they are envious of them.
G.. Sometimes the prize was deserved and was based on the score they were told they had earned on a quiz. But sometimes it was not based on their score at all.

One genetic mutation(基因突變)occurs on average for every 15 cigarettes that a typical lung-cancer patient smokes, according to a study that has found for the first time all of the mutations happen during the lifetime of a cancer patient.
Scientists have completed a full genetic examinations of the genomes（基因組） of cancer patients, and hope the information will lead to a basic understanding of the causes of cancer—and possibly drugs and treatments—by making out the mutations that turn a healthy cell into a cancerous tumor cell.
They studied a lung-cancer patient who had about 23,000 DNA mutations in his lung cells that were connected with exposure(暴露) to the toxins found in cigarette smoke and had built up over his lifetime.
They also looked at a patient with malignant melanoma(惡性黑色腫瘤), the most dangerous form of skin cancer, who had got 30,000 special mutations known to be connected with exposure to sunlight.
Scientists believe this new finding into the genetics of cancer will finally lead to new drugs and perfect treatments that aim at the specific changes to the gene that cause the disease, as well as new techniques for discovering following cancers that have escaped from treatment in other parts of the body.
“For the first time, we have a complete map of all mutations in a cancer cell,” said Dr. Peter Campbell, who led the Cancer Genome project to work out the whole DNA system of tumor cells in order find the mutations.
A similar method was performed on the cells of a patient with skin cancer, which is how the researchers were able to show that the malignant skin cells contained changes that resulted from exposure to light.
“These are the two main cancers in the developed world for which we know the chief exposure. For lung cancer it is cigarette smoke, and for malignant melanoma it is exposure to sunlight,” Professor Campbell said.
小題1:What can the genetic examination of the genomes of cancer patients be used for?
A．To help the professors to win the Nobel Prizes.
B．To advance the study of reason and cure of cancer.
C．To make the medicine industries earn more money.
D．To help the cancer patients reduce their pain.
小題2:The underlined word in the third paragraph can be placed by_____.
A．smokeB．sunlightC．cellD．poison
小題3:Which of the following statements is right according to the passage?
A．The lung-cancer patient had 30,000 mutations in his lung cells.
B．The genetics of cancer will finally lead to new drugs soon.
C．It’s the first time that people mapped mutations in a cancer cell.
D．Dr. Peter tries to invent a new drug with the DNA system.
小題4:What’s the similarity between malignant melanoma and skin cancer of patients?
A．Their smoking too much in daily life.
B．Their receiving too much sunshine.
C．Their refusing to accept treatment.
D．Their interest in travelling abroad.

Boris Worm of Dalhousie University in Nova Scotia, Canada, led the international team that did the study. Professor Worm says species have recently been disappearing from oceans at increasing speed. At this rate, he says, all seafood species could collapse by 2048 and seafood supplies from the world’s ocean could be almost gone by then.
Other studies have also warned about the dangers of overfishing and the effects on ocean environments. But not everyone thinks the oceans are likely to be empty in fifty years. Some scientists said parts of the world do have problems, but others are doing a good job of protecting fish populations. Government officials in several countries with large fishing industries also questioned the research.
The study appeared earlier this month in Science magazine.
The researchers say damage to oceans affects not only fish populations but also the productivity of ecosystems. These complex systems help control water quality. The scientists say the loss of different kinds of sea life appeared to increase the risk of fish kills and beach closures from harmful algae growth.
The scientists examined the results of thirty-two experiments and observed forty-eight protected areas. They also looked at records of catches worldwide. They studied records from the United Nations Food and Agriculture Organization for nineteen fifty to two thousand three. And they examined archeological information and other historical records for twelve coastal areas. That research reached back over a thousand years.
Boris Worm says the findings were, in his words, "beyond anything we suspected." But he also said the situation is not too late to correct. He said that with good fisheries management, some species could completely recover in three to ten years.
小題1:Which of the following isn’t the damage to the ocean?     
A．The species of fish in the ocean are reducing.
B．Sea water is polluted.
C．Sea water quality is improved.
D．Less productivity of ecosystem.
小題2:The conclusion of the research led by Boris Worm is _________. 
A．unbearableB．unbelievable
C．doubtfulD．Convincing
小題3:The research led by Boris Worm _________.          
A．was conducted by scientists from Canada
B．referred to information of many countries
C．lasted from 1950 to 2003
D．referred to records dating back to over 1,000 years ago.
小題4:Which of the following statements is NOT true?      
A．It’s too late to take action to improve the situation.
B．Some species will recover with efforts.
C．Boris Worm hopes that people take the warning serious.
D．Boris Worm shows great concern about ecosystem.

An early invention by Albert Einstein has been rebuilt by scientists at Oxford University. They are trying to develop an environmentally friendly refrigerator that runs without electricity.
We all know that modern fridges cause damage to the environment. They work by using a kind of man-made greenhouse gas called Freon (氟里昂), which is far more damaging than carbon dioxide.
Now Malcolm McCulloch, an electrical engineer at Oxford, is leading a three-year project to develop appliances that can be used in places without electricity.
His team has completed a prototype (樣機(jī)) of a fridge patented in 1930 by Einstein. It used only pressurized gases to keep things cold. The design was partly used in the first refrigerators, but the technology was dropped when more efficient compressors (壓縮機(jī)) became popular in the 1950s. That meant a switch to using Freon.
Einstein's idea uses butane (丁烷) and water and takes advantage of the fact that liquids boil at lower temperatures, when the air pressure around them is lower.
"If you go to the top of Mount Qomolangma, water boils at a much lower temperature than it does when you're at sea level and that's because the pressure is much lower up there," said McCulloch.At one side is the evaporator (蒸發(fā)器), a bottle that contains liquid butane. "If you introduce a new vapor above the butane, the liquid boiling temperature decreases and, as it boils off, it takes energy from the surroundings to do so," says McCulloch. "That's what makes it cold."
The gas fridges based on Einstein's design were replaced by Freon-compressor fridges partly because Einstein's design was not very efficient. But McCulloch thinks that by changing the design and replacing the types of gases used it will be possible to quadruple (翻兩番) the efficiency.
However, McCulloch's fridge is still in its early stages. "It's very much a prototype," he said. "Give us another month and we'll have it working."
小題1: According to the passage, an early invention by Albert Einstein _______.
A．has been rediscovered because it costs much less and works more efficiently
B．is being redesigned because it could be used in places without electricity
C．has just been found to be energy-saving and environmentally friendly
D．will be fully made use of and become the fridge of the future
小題2:Which of the following is TRUE according to the text?
A．Freon was used in fridges long before the 1950s.
B．Freon is what makes current fridges big polluters.
C．McCulloch thinks he could improve Einstein's design by using other types of vapors.
D．The fridge Malcolm McCulloch and his team designed will be put into production soon.
小題3:We can learn from the text that the prototype completed _______.
A．changed the air pressure around it
B．was tested on the top of Mount Everest
C．increased the liquid boiling temperature
D．used only pressurized gases to keep things cold
小題4:McCulloch's words in Paragraph 6 _____.
A．serve as an explanation for the principle behind Einstein's fridge
B．give you the reason why Einstein's fridge was not efficient
C．tell you how to take advantage of low air pressure
D．show you how Einstein's fridge works

“My kids really understand solar and earth-heat energy,” says a second-grade teacher in Saugus, California. “Some of them are building solar collectors for their energy course.” These young scientists are part of City Building Educational Program (CBEP), a particular program for kindergarten through twelfth grade that uses the stages of city planning to teach basic reading, writing and math skills and more.
The children don’t just plan any city. They map and analyze (分析) the housing, energy, and transportation requirements of their own district and foretell its needs in 100 years. With the aid of an architect (建筑師) who visits the classroom once a week, they invent new ways to meet these needs and build models of their creations. “Designing buildings of the future gives children a lot of freedom,’’ says the teacher who developed this program. “They are able to use their own rich imagination and inventions without fear of blame, because there are no wrong answers in a future context. In fact, as the class enters the final model-building stage of the program, an elected ‘official’ and ‘planning group’ make all the design decisions for the model city and the teacher steps back and becomes an adviser.
CBEP is a set of activities, games and imitations that teach the basic steps necessary for problem-solving: observing, analyzing, working out possible answers, and judging them based on the children’s own standards.
小題1:The program is designed to_________.
A．direct kids to build solar collectors
B．train young scientists for city planning
C．develop children’s problem-solving abilities
D．help young architects know more about designing.
小題2:An architect pays a weekly visit to the classroom to ________.
A．find out kids’ creative ideasB． help kids with their program
C． discuss with the teacherD． give children a lecture
小題3:Who is the designer of the program?
A．An official.B．An architect.C．A teacher.D．A scientist
小題4:The children feel free in the program because __________.
A．they can design future buildings themselves
B．they have new ideas and rich imagination
C．they are given enough time to design models
D．they need not worry about making mistakes

A controversial new study has claimed that men really are more intelligent than women．The study concluded that men’s IQs are almost four points higher than women’s.
British-born researcher John Philippe Ruston says the finding could explain why so few women make it to the top in the workplace.
He claims the “glass ceiling” phenomenon is probably due to inferior intelligence，rather than lack of opportunity.
The University of Western Ontario psychologist reached his conclusion after scrutinizing the results of university ability tests taken by 1 00,000 students aged 17 and 18 of both sexes.
A focus on the factors such as the ability to quickly grasp a complex concept，verbal reasoning skills and creativity― some of the key factors of intelligence ―showed the male teenagers had IQs that were an average of 3.63 points higher. The average person has an IQ around 100.The findings，which held true for all classes and levels of education, overturn 100 year opinion that men and women average the same in general mental ability. They also conflict with evidence that girls do better in school exams than boys.
But Professor Ruston argues that the faster maturing of girls leads to them outshining boy in the classroom.
小題1: The report is mainly about ______.
A．a(chǎn) study that shows men are cleverer than women
B．the “glass ceiling” phenomenon
C．Professor Ruston’s theory on IQ
D．the difference between male and female
小題2: The underlined word “scrutinizing” in the fourth paragraph probably means ______.
A．making upB．carrying outC．examining carefullyD．looking at
小題3: We can infer that the average woman has an IQ of ______.
A．a(chǎn) little less than 100B．100
C．more than 100D．96.37
