Satellites are an important part of our ordinary lives.For example, the information for weather forecasts is sent by satellite.Some satellites have cameras which take photographs of the Earth to show how clouds are moving.Satellites are also used to connect our international phone calls.
Computer connections of the World Wide Web and Internet also use satellites. Many of our TV programs come to US through satellites.Airplane pilots also sometimes use a satellite to help them find their exact location.
We use satellites to send television pictures from one part of the world to another.They are usually 35,880 kilometers above the equator.Sometimes we can see a satellite in the sky and it seems to stay in the same place.This is because it is moving around the world at 11,000 kilometers an hour—exactly the same speed that the earth rotates.A satellite must orbit the Earth with its antennae(天線)facing the earth.Sometimes, it moves away from its orbit,So there are little rockets on it which are used to put the satellite back in the right position.This usually happens about every five or six days.
Space is not empty! Every week, more and more satellites are sent into space to orbit the Earth.A satellite usually works for about 10-12 years.Satellites which are broken are sometimes repaired by astronauts or sometimes brought back to Earth to be repaired.Often,very old or broken satellites are left in space to orbit the Earth for a very long time.This is very serious because some satellites use nuclear power and they can crash into each other.

We can stay young forever. That is the message Dr. Shen Ziyin wants to give the world. And the Chinese doctor claims that he has found an answer to the problems of aging.
His solution is a herbal medicine to slow the process of aging.
Dr. Shen Ziyin has been trained in Western medicine. At the same time he studied traditional Chinese medicine. And, he has been working for the past forty years to put together the best of both and find a cure for aging. He has
taken a hint from its aging process. It is responsible for the level of activity that the human bodies go through Studies conducted by Dr.Shen show that herbal medicine based on the shen system slow the the ancient Chinese medicine system called “shen”.
According to Shen, it is the kidney(腎臟)which adjusts the functioning of the body as well as aging process, says a report in The Telegraph newspaper.
We notice that when people grow old, they have reduced strength, loss of hair, backache, weakness in general, and wrinkles, among others. This happens because when people grow old, their bodies produce T-cells. These T-cells contain a particular substance called Fas. Fas makes the cells in the body destruct themselves.
So the only way to slow down aging is to slow the production of T-cells in the body. This can happen if people eat low calorie food. Then the body is not active enough to produce extra T-cells. But, is going hungry all the time a good price to pay for staying young?
This is where Dr. Shen’s herbal medicine comes in. But how effective it will be, only time can tell.
【小題1】How did Dr. Shen find the solution to the problem of aging?
A.By studying Western medicine. |
B.By learning traditional Chinese medicine. |
C.By combining both Western and Chinese medicine. |
D.By doing research on both Western and Chinese people. |
A.Medical treatment. | B.People’s good kidney. |
C.Level of people’s activity. | D.Positive life attitude. |
A.their bodies produce T-cells |
B.their bodies are unable to fight diseases |
C.they have reduced strength, loss of hair |
D.they become weaker and weaker |
A.producing more low calorie food allows people to keep young |
B.the more Chinese herbal medicine people drink, the better for health |
C.people should try to quicken the production of T-cells in the body |
D.it remains unknown how effective Dr. Shen’s herbal medicine is |

There are new findings that not enough sleep may cause people to gain weight. Researchers say a lack of sleep can produce hormonal(激素的) changes that increase feelings of hunger.
In one study, researchers in the United States examined information on more than 1000 people. The people had taken part in a long-term study of sleep disorders.
Some people slept less than five hours a night. They had 15 percent higher blood levels of a hormone called ghrelin than people who slept eight hours. And they had 15 percent less of the hormone leptin. Experts say ghrelin helps make people feel hungry; leptin makes you feel full.
The scientists say these hormonal changes may be a cause of obesity in Western societies. They note the combination that sleep limitation is common and food is widely available.
The results were not affected by how much people exercised. People who are awake longer have more time to burn energy. But the researchers say loss of sleep may increase hunger especially for high-calorie foods, so people gain weight. It seems that, for survival, the body may be designed to store more fat during times with less sleep.
Researchers from Stanford University in California and the University of Wisconsin did the study. They found that the best amount of sleep for weight control is 7.7 hours a night.The Public Library of Science published the findings in its journal Medicine . Internet users can read the full study, free of charge, at plos. org.
【小題1】Not enough sleep can cause obesity by ______.
A.burning more of your energy |
B.making you want to eat more food |
C.keeping you from doing exercise |
D.helping you feel great without food |
A.have your ghrelin level rise and leptin level drop |
B.have your leptin level rise and ghrelin level drop |
C.have your ghretin and leptin levels properly balanced |
D.have your hunger increase and your weight decrease |
A.Only on the Internet |
B.only in Medicine |
C.Both on the Internet and in Medicine |
D.Neither on the Internet nor in Medicine |

Poor Oral Health Leads to Social and Emotional Problems
A new report says nearly four-billion people have major tooth decay, or cavities. That number represents more than half of the world's population. Health officials are warning that failure to repair cavities can lead to social and emotional problems.
Wagner Marcenes is with the Institute of Dentistry at Queen Mary, University of London. He led a team of researchers as part of the Global Burden of Disease 2010 study. About 500 researchers attempt to collect and examine studies about all major diseases. They used the information to estimate rates of the infection.
The report says untreated tooth decay is the most common of all 291 major diseases and injuries. Professor Marcenes says cavities or holes in permanent teeth are also known as caries.
"Caries is a chronic disease that shares the same risk factors as cancer, cardiovascular disease. What we're having now is an increase in disease from highly developed countries happening in sub-Saharan Africa and probably it will be in other areas of Africa, too."
He says an increase in tooth decay in Africa could be a result of developing countries becoming more like Western nations.
"It is likely to be related to a change in diet. Our industrialized diet leads to chronic disease, which includes caries. And that may be the main explanation."
Western diets are rich in sugar, a leading cause of health problems in the mouth. Wagner Marcenes says oral health problems can have a major effect on a person's quality of life. First, cavities make eating difficult. Second, people may change what they eat. They may eat softer foods that are not hard to chew. However, softer foods are often fattier foods.
But professor Marcenes says the biggest issue in tooth decay is both social and mental. He says the researchers found strong evidence that the mouth has a big influence on socialization. He says many people want to hide bad teeth. They smile less and communicate less.
Wagner Marcenes is calling for an "urgent, organized, social response" to the widespread lack of oral health. He believes in a natural method to fight tooth decay by having a healthier diet. He is also calling for the development of new and less costly dental materials and treatments.
【小題1】From the passage, we know that Wagner Marcenes ______.
A.works as the leader of the Institute of Dentistry at Queen Mary, University of London. |
B.a(chǎn)nd his researchers accumulate some studies to find out some ways to cure all major disease. |
C.is in charge of the activity to estimate the infection rate with the collected and examined studies about all major studies. |
D.thinks that the most serious problem caused by tooth decay is cancer that will last for a long time. |
A.is listed in the most common of all 291 major diseases and injuries which will last for a long time.. |
B.is closely related to industrialized diet which calls for people to eat slowly. |
C.increases in Africa now because developing countries are becoming developed countries. |
D.will cause phychological disorder which will affect people’s communication. |
A.a(chǎn)rouse people’s concern about caries and take measures to deal with it. |
B.tell the result of the Global Burden of Disease 2010 study. |
C.warn people in Africa to adjust their diet to prevent caries. |

When Scotsman Alexander Graham Bell invented the telephone in 1876, it was a revolution in communication. For the first time, people could talk to each other over great distances almost as clearly as if they were in the same room. Nowadays, though, we increasingly use Bell' s invention for taking photographs, accessing the internet, or watching video clips, rather than talking. Over the last two decades a new means of spoken communication has appeared: the mobile phone.
The first real mobile telephone call was made in 1973 by Dr Martin Cooper, the scientist who invented the modem mobile handset. Within a decade, mobile phones became available to the public. The streets of modem cities began to feature sharp-suited characters shouting into giant plastic bricks. In Britain the mobile phone quickly became the same with the "yuppie" , the new type of young urban professionals who carried the expensive handsets as status symbols. Around this time many of us said that we would never own a mobile phone.
But in the mid-90s, something happened. Cheaper handsets and cheaper calling rates meant that, almost overnight, it seemed that everyone had a mobile phone. And the giant plastic bricks of the 80s had changed into smooth little objects that fitted nicely into pockets and bags.
Moreover, people' s timekeeping changed. Younger readers will be amazed to know that, not long ago, people made spoken arrangements to meet at a certain place at a certain time. But later Meeting times became approximate under the new order of communication: the Short Message Service (SMS) or text message. Going to be late? Send a text message! It takes much less effort than arriving on time, and it' s much less awkward than explaining your lateness face to face and the text message has changed the way we write in English. Traditional rules of grammar and spelling are much less important when you' re sitting on the bus, hurriedly typing "Will B 15mm late - C U @ the bar. Sorry! - )".
Alexander Graham Bell would be amazed if he could see how far the science of telephony has progressed in less than 150 years.If he were around today, he might say "That' s gr8! But I' m v busy rite now.Will call U 2nite."
【小題1】What does the underlined part in Para. 2 refer to?
A.Houses of modern cities. | B.Sharp-suited characters. |
C.New type of professionals. | D.Mobile phones. |
A.People were more likely to be late for their meeting. |
B.SMS made it easier to inform each other. |
C.Young people don' t like unchanging things. |
D.Traditional customs were dying out. |
A.Call U@ SKUg8 2nite. | B.IM2BZ2CU 2nite. |
C.CU@ the bar g8 2nite. | D.W84U@ SKUg8 2nite. |
A.Alexander Graham' s invention. |

It's not about how much money you make, and it's not about who your daddy is. We're talking about being attractive in general, whether it's on a job interview or just gaining the respect of your colleagues . . .
Ask lots of questions
If you come across as a know-it-all (even if you really do know it all!), it really pushes people away. Rather, asking lots and lots of questions makes people feel like you care, you can be trusted.
Great body language
Your body language says a lot about you - it says whether you have confidence, or simply if you really care. Talking physically, it is one of the most important physical characteristics you need!
Stay busy
Always have something to do. Have you ever seen someone just sitting around, doing nothing? How unattractive. Always be busy with something, even if for some reason you have to make something up.
Show your pearly whites (or just smile)
Smile more, no matter how ugly your teeth are. I'm not kidding about this one. It's not all about the teeth. If you are smiling genuinely, you can draw everyone for 100 meters around to you.
Wear what fits
Wear clothing that fits you. For women, wearing tight pants or shirts is not attractive. Things that just fit you and your shape are the best but not tight. Wear things that fit you nicely, please . . . And for goodness sake, both sexes, stay away from logos and printed shirts! Most people you may ask do not find this attractive. Stop being some company's billboard(廣告牌).
Be interested in other man
Be interested in the other person. Don't talk about. If you are truly interested in the person, it will come across. And if you want to talk about yourself, you'll find that putting the other person first actually opens him up to return the favor and ask you questions. See how fun this is?
【小題1】It is your ________ that makes you attractive.
A.your family background |
B.fashionable tight clothes |
C.your appearance and your wealth |
D.proper body language and behavior |
A.a(chǎn)lways smile and show your pearly teeth |
B.keep asking lots of questions |
C.a(chǎn)re interested in other people’s personal affairs |
D.a(chǎn)lways wear clothes that fit you |
A.gain praises from your boss and colleagues |

D.get promoted in your company |
A.Wearing a shirt with printed logos |

Cooler temperatures, attractive colors, smaller crowds autumn is the perfect time for travel and tourism. Here, three places are listed as the best fall trip destinations. Don’t worry if you can’t go to these places. By reading this page, we hope to take you on grand tour and let you experience fun and culture around the world.
Cannstatter Volkfest, Stuttgart, Germany Stuttgart’s Cannstatter Volkfest is listed as the world’s second largest beer-drinking event––– following Munich’s Oktoberfest. But it is considered Germany’s more authentic celebration of local heritage and, of course, beer. Started as an agricultural fair in 1818––– a symbolic 24-meter-high “fruit column” pays homage (敬意) to the past ––– the three-week festival (from September 23 to October 9 this year) features live music, a re-created Alpine village, and carnival rides. In addition, Stuttgart is recognized as a global car capital. Both the Mercedes-Benz and Porsche museums are worth a visit. |
Churchill, Manitoba, Canada Here in the northern Canadian town at Hudson Bay, visitors can see the area’s most famous fall residents ––– polar bears. More than a thousand of the world’s largest land carnivores migrate through the “polar bear capital of the world” during October and November, when the first ice forms on the edge of Hudson Bay. The frozen conditions make it easier for hungry bears to hunt for seals (by walking instead of swimming). Under the snowy, winter weather, visitors can hardly have too many clothes to put on. Insulated boots, jackets, and gloves; layered clothing; thermal underwear; and woolen socks and hats are required. |
Dublin, Ireland The Ireland’s capital and largest city is a center for arts, entertainment, culture and commerce. With few tourists and lower temperatures, fall is the ideal season for walking the historic Georgian streets and cruising the River Liffey. Visitors can explore the city’s 20 square kilometers of public gardens, nature reserves, and parks, including St. Stephen’s Green, which borders Grafton Street, one of the world’s most expensive retail locations. Along the way, enjoy traditional, paper-wrapped fish and chips at Leo Burdock. Healthier eats will be on the menu on October 31, when more than 12,000 runners are expected for the National Lottery Dublin Marathon, named “the Friendly Marathon” for the friendly crowds cheering there. |
A.care for fun and culture around the world |
B.have planned to go for traveling this autumn |
C.hate to have their holidays in other seasons |
D.have not ever been to Europe and America |
A.enjoy live music at the beer – drinking festival |
B.watch polar bears hunt seals |
C.taste traditional, paper–wrapped fish and clips |
D.win a prize in “the Friendly Marathon” |
A.Car exhibitions will be held for two months |
B.It’s not necessary to take more clothes with you to Churehill, Martitoba |
C.The beer–drinking event in German dates from the eighteenth century |
D.Your favourite goods might be available in the expensive shop in Dublin |
A.economics | B.science |
C.tourism | D.fashion |

Monitoring global warming usually requires a Ph. D. and enough maths to glaze your eyes. But that Francisco Lopez and Ruby Nostrant track(記錄)what climate change is doing to five different plants in Tucson, Arizona and they are only in the second grade.
“We are collecting data because the weather is changing and the plants are blooming,” Ruby explained.
Scores of other students at Borton Primary Magnet School and Sunnyside High School in Tucson are heading outdoors to be part of a new scientific push to figure out how the biological timing of the earth is changing. It’s a research project that the average person, even a kindergartner, can join in.
The National Phenology(生物氣候?qū)W)Network is calling on volunteers to help track early spring blooms and eventually changes in animals caused by global warming. It’s called Project Budburst. When it was first open to the public last year, thousands of people participated in 26 states.
“All people can contribute to it by tracking the timing of flowering events or leaf-out events for plants and animals in their backyard,” said Phenology Network director Jake Weltzin. He calls the volunteers “citizen-scientists.”
The idea is that tracking flowers blooming—especially lilacs(丁香); which everyday people have helped track for decades—is fairly simple. The Website http://www.Windows.ucar.edu/ citizen_science/budburst/index.html gives directions on what to look for in different parts of the country.
University of Maryland professor David Inouye said it’s so easy to figure out what’s blooming that a lack of special knowledge isn’t a problem.
University of Arizona ecology graduate student Lisa Benton coordinated(協(xié)調(diào))the Tucson high school students as they looked at plants five minutes from their high school. Each student has specific guidelines and she’s been happy so far with the data she is getting. For his part, second-grader Francisco said he had fun helping out.
“I like going out in the desert,” he said. “I want to be an Einstein.”
【小題1】Francisco Lopez and Ruby Nostrant are monitoring global warming by __________.
