Astronomy is the oldest science known to man. Thousands of years ago man looked at the stars and wondered about the heavens. But man was limited by what he could see with his eyes alone.
The Greeks studied astronomy over 2,000 years ago. They could see the size, color, and brightness of a star. They could see its place in the sky. They watched the stars move as the seasons changed. But the Greeks had no tools to help themselves study the heavens.
Each new tool added to the field of astronomy helped man reach out into space. They did not know that the planet called Saturn(土星) had rings around it. Their sight was so limited that they could not see all the planets. In the early 1700s, people thought there were only six planets. Nepture(海王星), the last of eight planets to be discovered, was not seen until 1846.
Before the spectroscope(分光镜), man did not know what kind of gases was in the sun or other stars. Without the radio telescope, we didn’t know that radio noises came from far out in space.
Today, astronomy is a growing science. We had learned more in the last fifty years than in the whole history of astronomy.

Did you know that the position you choose to sleep in says something about what kind of person you are?
A study of 1,000British people has been done by Chris,a British professor and director of the Sleep Assessment and Advisory Service in the UK.It looked at the six most common sleeping positions and which personalities tend to match them.Have a look.
1. Fetus (胎儿) position – This is the most common sleeping position. About 41 percent of the participants said they sleep in this position. These sleepers may appear to be strong but they are usually sensitive (敏感的) and shy. The more they curl (蜷缩) up, the more worried they are.
2. Log position (树干睡姿) – This is the second most common position. People who sleep like a log are usually stubborn.
3. Yearner position (向往型睡姿) – This position says that you are open-minded and eager (急切的) to face challenges.
4. Soldier position – These sleepers lie on their backs with their arms down and close to the body. They are usually reserved and quiet.
5. Freefall position – People who sleep in this position are outgoing (外向的) but feel a lack of control in their lives. This is the least comfortable position.
6. Starfish position – People who sleep like this are good listeners, helpful, and uncomfortable being the center of attention.
【小题1】What is the main idea of this passage?

If you want to stay young, sit down and have a good think. This is the research finding of a team of Japanese doctors, who say that most of our brains are not getting enough exercise—and as a result, we are aging unnecessarily soon.
Professor Taiju Matsuzawa wanted to find out why otherwise healthy farmers in northern Japan appeared to be losing their ability to think and reason at a relatively early age, and how the process of aging could be slowed down.
With a team of colleagues at Tokyo National University, he set about measuring brain volumes of a thousand people of different ages and varying occupations.
Computer technology enabled the researchers to obtain precise measurements of the volume of the front and side sections of the brain, which relate to intellect (智能) and emotion, and determine the human character. (The rear section of the brain, which controls functions like eating and breathing, does not contract with age, and one can continue living without intellectual or emotional faculties.)
Contraction of front and side parts—as cells die off—was observed in some subjects in their thirties, but it was still not evident in some sixty- and seventy-year-olds.
Matsuzawa concluded from his tests that there is a simple remedy to the contraction normally associated with age—using the head. The findings show in general terms that contraction of the brain begins sooner in people in the country than in the towns. Those least at risk, says Matsuzawa, are lawyers, followed by university professors and doctors. White collar workers doing routine work in government offices are, however, as likely to have shrinking brains as the farm worker, bus driver and shop assistant. Matsuzawa’s findings show that thinking can prevent the brain from shrinking. Blood must circulate properly in the head to supply the fresh oxygen the brain cells need. “The best way to maintain good blood circulation is through using the brain,” he says, “Think hard and engage in conversation. Don’t rely on pocket calculators.”
【小题1】The team of doctors wanted to find out ________.
why certain people age sooner than others
B. how to make people live longer
C. the size of certain people’s brains
D. which people are most intelligent
【小题2】On what are their research findings based?
A survey of farmers in northern Japan.
B. Tests performed on a thousand old people.
C. The study of brain volumes of different people
D. The latest development of computer technology.
【小题3】The word “subjects” in Paragraph 5 means ________.
something to be considered
B. branches of knowledge studied
C. persons chosen to be studied in an experiment
D. any member of a state except the supreme ruler.
【小题4】According to the passage, which people seem to age slower than the others?
A.Lawyers. | B.Farmers. |
C.Clerks. | D.Shop assistants. |

When several different people look at the same person,it's not unusual for each of them to see different things;when you alone observe one behavior or one person at two different times,you may see different things.The following are but some of the factors that lead to these changing perceptions(感知认可).
(1)Each person's perceptions of others are formed by his or her own cultural conditioning education,and personal experiences.
(2)Sometimes perceptions differ because of what we choose to observe and how we deal with what we've observed.It is not necessarily true that person's perception is based on observations of a particular person.Your observations may be totally controlled by what others have told you about this person;or you may focus (聚集)primarily on the situation or role relationship.Most people do not use the same yardstick(标准)to measure their parents,their friends and strangers.
(3)Sometimes we see only what we want to see or don't see what may be obvious to others because of our own needs,desires,or temporary emotional states.This is a process known as selective perception.Selective perception is obviously more difficult when contradictory (矛盾的)information is particularly obvious,but it can be done.We can ignore(忽视)the “stimulus”.He's basically a good boy so what I saw was not shoplifting.
We can reduce the importance of the contradictory information—All kids(孩子)get into mischief(顽皮).Taking a book from the bookstore isn't such a big deal.“We can change the meaning of the contradictory information.” It wasn't shoplifting because he was going to pay for it later.
【小题1】The first factor given by the author that affects our perception is ________.
A.the abilities of one's auditory (听觉的)and visual (视觉的)sensors |
B.cultural background and personal experiences |
C.experiences one learns from others |
D.critical measures taken by other people |
A.one is likely to take all aspects(方面)to consideration |
B.one pays more attention to his/her advantages |
C.children often differ from grown?ups in perception |
D.one tends to choose certain cues(提示)to look for |
A.their measuring yardsticks are not the same |
B.either of them may be slow to catch information |
C.the time for observation is not long enough |
D.each of them uses different language to express his/her impressions |

The idea of being able to walk on water has long interested humans greatly. Sadly, biological facts prevent us ever accomplishing such a thing without artificial aid --- we simply weigh too much, and all our mass pushes down through our relatively small feet, resulting in a lot of pressure that makes us sink.
However, several types of animals can walk on water. One of the most interesting is the common basilisk Basilicus basilicus, a lizard(蜥蜴)native to Central and South America. It can run across water for a distance of several meters, avoiding getting wet by rapidly hitting the water’s surface with its feet. The lizard will take as many as 20 steps per second to keep moving forward. For humans to do this, we’ll need huge feet that we could bring up to our ears in order to create adequate “hitting.”
But fortunately there is an alternative: cornflour. By adding enough of this common thickening agent to water (and it does take a lot), you can create a “non-Newtonian” liquid that doesn’t behave like normal water. Now if the surface of the water is hit hard enough, particles(粒子)in the water group together for a moment to make the surface hard. Move quickly enough and put enough force into each step, and you really can walk across the surface of an adequately thick liquid of cornflour.
Fun though all this may sound, it’s still rather messy and better read about in theory than carried out in practice. If you must do it, then keep the water wings handy in case you start to sink --- and take a shower afterward!
【小题1】Walking on water hasn’t become a reality mainly because humans _______.
A.are not interested in it |
B.have biological limitations |
C.have not invented proper tools |
D.are afraid to make an attempt |
A.It is light enough to walk on water. |
B.Its huge feet enable it to stay above water. |
C.It can run across water at a certain speed |
D.Its unique skin keeps it from getting wet in water |
A.To create a thick liquid. |
B.To turn the water into solid. |
C.To help the liquid behave normally. |
D.To enable the water to move rapidly. |
A.It is risky but beneficial. |
B.It is interesting and worth trying |
C.It is crazy and cannot become a reality |
D.It is impractical; though theoretically possible |

Scientists today are making greater effort to study ocean currents (洋流) . Most do it using satellites and other high-tech equipment. However, ocean expert Curtis Ebbesmeyer does it in a special way -- by studying movements of random floating garbage. A scientist with many years’ experience, he started this type of research in the early 1990s when he heard about hundreds of athletic shoes washing up on the shores of the northwest coast of the United States. There were so many shoes that people were setting up swap meets to try and match left and right shoes to sell or wear.
Ebbesmeyer found out in his researches that the shoes — about 60,000 in total — fell into the ocean in a shipping accident. He phoned the shoe company and asked if they wanted the shoes back. As expected, the company told him that they didn't. Ebbesmeyer realized this could be a great experiment. If he learned when and where the shoes went into the water and tracked where they landed, he could learn a lot about the patterns of ocean currents.
The Pacific Northwest is one of the world's best areas for beachcombing(海滩搜寻) because winds and currents join here, and as a result, there is a group of serious beachcombers in the area. Ebbesmeyer got to know a lot of them and asked for their help in collecting information about where the shoes landed. In a year he collected reliable information on 1, 600 shoes. With this data, he and a colleague were able to test and improve a computer program designed to model ocean currents, and publish the findings of their study.
As the result of his work, Ebbesmeyer has become known as the scientist to call with questions about any unusual objects found floating in the ocean. He has even started an association of beachcombers and ocean experts, with 500 subscribers from West Africa to New Zealand. They have recorded all lost objects ranging from potatoes to golf gloves.
【小题1】The underlined phrase swap meets in Paragraph 1 is closest in meaning to ______________.
A.fitting rooms |
B.trading fairs |
C.business talks |
D.group meetings |
A.what caused the shipping accident |
B.when and where the shoes went missing |
C.whether it was all right to use their shoes |
D.how much they lost in the shipping accident |
A.By collecting information from beachcombers. |
B.By studying the shoes found by beachcomber. |
C.By searching the web for ocean currents models. |
D.By researching ocean currents data in the library. |
A.traveling widely the coastal cities of the world |
B.making records for any lost objects on the sea |
C.running a global currents research association |
D.phoning about any doubtful objects on the sea |
A.To call people's attention to ocean pollution. |
B.To warn people of shipping safety in the ocean. |
C.To explain a unique way of studying ocean currents. |

A world-famous Canadian author, Margaret Atwood, has created the world’s first long-distance signing device(装置), the LongPen.
After many tiring……from city to city, Atwood thought there must be a better way to do them . She hired some technical experts and started her own company in 2004. Together they designed the LongPen. Here’s how it works: The author writes a personal message and signature on a computer tablet(手写板) using a special pen. On the receiving end, in another city, a robotic arm fitted with a regular pen signs the book. The author and fan can talk with each other via webcams(网络摄像机) and computer screens。
Work on the LongPen began in Atwood’s basement(地下室). At first, they had no idea it would be as hard as it turned out to be. The device went through several versions, including one that actually had smoke coming out of it. The investing finally completed, teat runs w ere made in Ottawa, and the LongPen was officially launched at the 2006 London Book Fair. From here , Atwood conducted two transatlantic book signings of her latest book for fans in Toronto and New York City.
The LongPen produces a unique signature each time because it copies the movement of the author in real time. It has several other potential applications. It could increase credit card security and allow people to sign contracts from another province. The video exchange between signer and receiver can be recorded on DVD for proof when legal documents are used.
“It’s really fun”, said the owner of a bookstore, who was present for one of the test runs. “Obviously you can’t shake hands with the author but there are chances for a connection that you don’t get from a regular book signing..
The response to the invention has not been all favorable. Atwood has received criticism from authors who think she is trying to end book tours. But she said, “It will be possible to go to places that you never got sent to before because the publishers couldn’t afford it.”
【小题1】Why did Atwood decide to invent the LongPen?
A. To set up her own company
B. To win herself greater popularity
C. To write her books in a new way
C. To make book signings less tiring
【小题2】How does the LongPen work?
A.I copies the author’s signature and prints it on a book. |
B.It signs a book while receiving the author’s signature. |
C.The webcam sends the author’s signature to another city. |
D.The fan uses it to copy the author’s signature himself. |
A.It has been completed but not put into use. |
B.The basement caught fire by accident. |
C.Some versions failed before its test run. |
D.The designers were well-prepared for the difficulty. |
A.To draft legal documents. |
B.To improve credit card security |
C.To keep a record of the author’s ideas. |
D.To allow author and fan to exchange videos |
A.Atwood doesn’t mean to end book tours. |
B.Critics think the LongPen is of little use |
C.Bookstore owners do not support the LongPen |
D.Publishers dislike the LongPen for its high cost |

One might expect that the evergrowing demands of the tourist trade would bring nothing but good for the countries that receive the holidaymakers. Indeed, a rosy picture is painted for the longterm future of the holiday industry. Every month sees the building of a new hotel somewhere. And every month another rockbound Pacific island is advertised as the ‘last paradise(天堂) on earth’.
However, the scale and speed of this growth seem set to destroy the very things tourists want to enjoy. In those countries where there was a rush to make quick money out of seaside holidays, overcrowded beaches and the concrete jungles of endless hotels have begun to lose their appeal.
Those countries with little experience of tourism can suffer most. In recent years, Nepal set out to attract foreign visitors to fund developments in health and education. Its forests, full of wildlife and rare flowers, were offered to tourists as one more untouched paradise. In fact, the nature all too soon felt the effects of thousands of holidaymakers traveling through the forest land. Ancient tracks became major routes for the walkers, with the consequent exploitation of precious trees and plants.
Not only can the environment of a country suffer from the sudden growth of tourism. The people as well rapidly feel its effects. Farmland makes way for hotels, roads and airports; the old way of life goes. The onetime farmer is now the servant of some multinational organization; he is no longer his own master. Once it was his back that bore the pain; now it is his smile that is exploited. No doubt he wonders whether he wasn't happier in his village working his own land.
Thankfully, the tourist industry is waking up to the responsibilities it has towards those countries that receive its customers. The protection of wildlife and the creation of national parks go hand in hand with tourist development and in fact obtain financial support from tourist companies. At the same time, tourists are being encouraged to respect not only the countryside they visit but also its people.
The way tourism is handled in the next ten years will decide its fate and that of the countries we all want to visit. Their needs and problems are more important than those of the tourist companies. Increased understanding in planning worldwide tourism can preserve the market for these companies. If not, in a few years' time the very things that attract tourists now may well have been destroyed.
【小题1】What does the author indicate in the last sentence of Paragraph 1?
A.The Pacific island is a paradise. |
B.The Pacific island is worth visiting. |
C.The advertisement is not convincing. |
D.The advertisement is not impressive. |
A.its natural resources are untouched |
B.its forests are exploited for farmland |
C.it develops well in health and education |
D.it suffers from the heavy flow of tourists |
A.They are happy to work their own lands. |
B.They have to please the tourists for a living. |
C.They have to struggle for their independence. |
D.They are proud of working in multinational organizations. |
A.The number of tourists. |
B.The improvement of services. |
C.The promotion of new products. |
D.The management of tourism. |

EVERYONE has those nights – you lie in your bed for hours, tossing and turning, totally unable to fall asleep. You wish you could just turn your brain off as if it were a light. That would make things much easier, wouldn’t it?
Now it looks like you are one step closer to this wild dream of yours – scientists from Oxford University, UK have just discovered the “switch” that tells the brain to go to sleep, reported Forbes.
To understand the study, you first need to know that there are two mechanisms (机能) that regulate sleep. There’s one that we’re already familiar with – our body clock, which works in a 24-hour cycle based on the light changes throughout the day.
The other one is what scientists call the sleep “homeostat (动态平衡系统)”. This mechanism has nothing to do with daylight. Instead, it keeps track of the brain’s waking hours and urges it to rest if it has been awake for a long time. “It is similar to the thermostat (自动调温器) in your home. A thermostat measures temperature and switches on the heating if it’s too cold,” Professor Gero Miesenböck, who led the study, told The Telegraph.
Our bodies use both of the mechanisms to regulate sleep. “The body clock says it’s the right time, and the sleep thermostat has built up pressure during a long waking day,” explained Miesenböck.
There is no way that scientists can trick the body clock. But with the sleep homeostat, there might be something they can do.
The researchers found that the sleep homeostat works by activating a specific group of nerve cells, or neurons, in the brain. They tested their theory on fruit flies by removing the neurons from the insects’ brains. And as expected, they found that the flies without the homeostat neurons did not keep a regular sleep pattern anymore.
Now that scientists have pinpointed (定位) the exact place in the brain – or, the “switch” – that regulates sleep, they can begin investigating (研究) how to activate these cells at any given time so that people can be sent to sleep instantly.
More importantly, figuring out how sleep mechanisms work may also help us to one day unravel one of the oldest mysteries of all: why do we need to sleep in the first place?
【小题1】What is the article mainly about?
A.A new way to treat sleep disorders. |
B.The discovery of the sleep “homeostat”. |
C.Advice on what to do when you fail to fall asleep. |
D.A comparison of the two mechanisms that regulate sleep. |
A.Through examples. |
B.With comparisons. |
C.Through cause and effect analysis. |
D.By presenting research findings. |
A.Generally, the sleep homeostat has less effect on people during the day than at night. |
B.There is little scientists can do to affect the way the sleep homeostat works. |
C.What makes us go to sleep at night is probably a combination of the two mechanisms. |
D.The more homeostat neurons there are in one’s brain, the more easily one can fall asleep. |
A.put up with | B.figure out | C.keep track of | D.take notice of |
