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（赤道）．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(天线)facing the earth．Sometimes, it moves away from its orbit（轨道），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（撞）into each other．

【推荐1】For centuries, humans have wondered whether there is life on Mars. Scientists have asked why Mars is losing its atmosphere. Last week, the question was answered with a song. “The answer is blowing in the wind,” said Michael Meyer, taking a line from a Bob Dylan song. Meyer is the lead scientist for NASA’s Mars Exploration Program. It turns out that solar winds from the sun are slowly blowing away Mars’ atmosphere.
Today, Mars has a thin atmosphere. It is cold and dry, with a desert-like environment. Jakosky says it used to be much more different. “When we look at ancient Mars, we see a different type of surface. One that had valleys looked like they were carved by water, lakes that were standing for a long period of time. We see an environment that was much more able to support liquid water.”
Recently they found a kind of liquid water that flows with salt down a mountain area of the planet. But it is not always there. Scientist Michael Meyer describes what they found: “We’re seeing water, with the salt that’s able to flow down the sides of the cliff. Why is this important? That means there is water on Mars, on the surface of Mars today.”
Scientists already knew that ice exists on Mars. So why is it important to find liquid water? Meyer explains: “It means that we have a resource. And when we're looking at sending humans to Mars, water is one of the key things that we need to have, not only for astronauts to drink, but also to make oxygen, to make fuel.”
Sending humans to Mars is still in the distant future. NASA is aiming for the 2030s. Both US government and private industries are developing rockets and spacecraft to get people to Mars.
1. Why is the atmosphere of Mars disappearing?| A．Because Mars doesn't have water to keep the atmosphere. |
| B．Because the atmosphere is affected by the earth. |
| C．Because the atmosphere is blown away by the solar wind. |
| D．Because Mars has no condition to make the atmosphere exist. |

【推荐2】This summer, NASA launched its latest robot Perseverance on a seventh-month journey to Mars. During the past decades, robot explorers on Mars have made great discoveries about the red planet, but they have never found clear-cut signs of creatures currently living there. Life, at least as we know it on Earth, simply does not seem probable on the Martian surface.
“If there’s any life on Mars now, it needs at least some liquid water,” Dr. Sumner said. “The surface of Mars now is very dry. Extremely dry. If there’s life on Mars now, it would be found deep underground.” Actually, there has been some evidence that liquid water is locked away beneath the surface, so perhaps there are sunless ecosystems hidden there, which are beyond the direct reach of our rovers and landers.
“Recent findings of methane and other gases in what’s left of Mars’ atmosphere are a potential signature,” Dr. Farley said, supporting the theory about underground water. Many microbes on Earth produce methane, so it is possible that the gas on Mars could be related to alien life-forms deep underground.
However, methane can also be created by a wide range of natural processes that have nothing to do with life. Some experts, like Dr. Sumner from the University of California Davis, say that the presence of the gas on Mars is “not a surprise” because it has all the geological processes it needs to produce the gas without life.
But even if we never find Martians, “Mars is a place we can go to answer some of the questions about life on Earth,” Dr. Sumner said. The red planet remains a time capsule of the era when life first began on our own world, and the direction it could have gone had all the factors that made our world possible, yet it turned out just not the right way.
1. Where can life on Mars possibly be?| A．In the methane. | B．On the surface. |

【推荐3】At first sight the planet Mars does not appear very welcoming to any kind of life. It has very little oxygen and water. The temperature at night is below 50 degrees and winds of 100 miles(161 kilometers) per hour cause severe dust storms. However, the surface of the planet seems to show that water flowed across it at some time in the past, and it is believed that there would be enough ice at the poles to cover the planet with water if it melted. Although there is no life on the Mars now, some scientists think there may have been some form of life a long time ago. At that time, the planet had active volcanoes(火山), the atmosphere was thicker and warmer, and there was water. In fact, in some ways the Mars may have been similar to the earth, where life exists.
Some people believe that the Mars could support life in the future if the right conditions were produced.The first step would be to warm the planet using certain gases which trap the sun’s heat in the planet’s atmosphere. With warmth, water and carbon dioxide, simple plants could begin to grow.These plants could slowly make the Mars fit to live on. It is judged that the whole process might take between 100, 000 and 200, 000 years. In the meantime, people could begin to live on the planet in a special closed environment.They would provide a lot of useful information about conditions on the Mars and the problems connected with living there.

【推荐1】Sharpshooters refer to those who are skilled at firing a gun and accurately hitting what they are aiming at. However, some fish are also called amazing sharpshooters. People wonder how they hit their targets without using tools? By spitting! The fish shoot so accurately that they rarely miss their target.
These amazing fish are archerfish (印度射水鱼).There are several different types of archerfish living in Southeast Asia. They spit at their dinner to catch it. To catch dinner, a fish first sets itself in a certain place, for example just below the surface of the water. It puts the tip of its mouth so it barely breaks through the water. Then, the fish waits for an unsuspecting insect to land on a leaf or branch hanging over the water.
When an unsuspecting, or unknowing insect lands, the fish attacks. The fish squeezes its gill (腮)covers very rapidly, which forces water into the fish's mouth. In the roof of its mouth the fish has a groove (槽）• The fish forms the small groove and its tongue into a narrow tube by pressing its tongue up against its groove. The water forced into the fish's mouth is forcefully pushed out of the fish's moulh through the tube. Archerfish have been known to send a stream up to 5 meters (16 feet). However, archerfish can only shoot insects up to 1-2 meters (3-6 feet) away due to their limited accuracy.
When the unsuspecting insect is hit with a sudden stream of water, it is knocked into or falls into the water. Once in the water, the insect becomes dinner. Archerfish learn how to spit when they are young. They get more accurate with practice. Adult archerfish rarely miss.
Within a meter, archerfish will often spring out of the water and grab an insect in their mouths.

【推荐2】“While animals can’t pick out precise numbers, they can understand that more is more. Interestingly, we know now that numerical competence is present on almost every branch of the animal tree of life,” says Andreas Nieder, a neurobiologist from the University of Tuebingen. “Different groups of animals obviously developed this competence independently from others and that strongly indicates that it has to be of adaptive value.”
Honeybees, for instance, can remember the number of landmarks they pass when searching for food in order to find their way back to the hive. The last common ancestor between honeybees and primates lived about 600 million years ago. But still, they evolved numerical competence that, in many respects, is comparable to vertebrate numerical competence. Also, for example, male frogs sing “advertisement” calls to attract females. The females, listening for the complexity of their calls, choose the male that sings the most calls.
Wolves are more likely to hunt successfully if they have the right number of wolves in their pack for the size of their prey: With prey like deer, only around six to eight wolves are needed, while hunting wild ox requires a pack of nine to thirteen. Their prey also uses this concept to protect themselves from predators — deer tend to live in large herds to reduce the chance of any individual becoming prey. So obviously they are assessing the number of individuals in their groups for their everyday life situations.
Despite these many examples of numerical competence in animals, this subject has not gotten many first-hand studies. “Many of these behavioral findings in the wild have usually been collected as by-products or accidental findings of other research questions,” says Nieder. He argues that more research needs to be done to fully understand the numerical competence.

【推荐3】The apples that hang invitingly from trees in Tom Brown’s orchard(果园)are likely not found in your local supermarkets. They are the 1, 200 varieties that Brown has recovered from six southern states. Most haven’t been sold for a century or more; some were transplanted from the last known trees of their kind. All are finding a new life here in Tom Brown’s orchard.
One such apple is the Junaluska. It came from the Cherokee Indians more than two centuries ago and was named after a 19th-century leader. It was popular in the South before disappearing from commercial(商业化的)production by 1900. Brown came across the Junaluska in 2001. At first, he became curious about its unfamiliar name. Then, Brown found that its shape, color, and taste were like no apple he had ever seen before. With the farmer’s permission, he took a clipping(枝条)from the tree for his orchard and set about reintroducing the apple to the world.
Hearing that other lost apples might still be found in the area, Brown went in search of them. However, one dead end led to another. He had no choice but to reach out to local newspapers for help. The articles he ran led to suggestions from readers, and soon Brown was tasting many more varieties that were once thought lost.
In 1905, there were more than 7, 000 apple varieties in the United States. Then things changed. People moved to cities and grew less of their own food, while large businesses preferred selling ones that were familiar and shipped easily. Brown is anxious to bring back as many of the extinct or nearly extinct varieties as possible.
“These were foods that people had once cared about deeply, and that had been central to their lives, ”Brown says. “It felt wrong to just let them die and be lost forever. Everyone is responsible for protecting agricultural heritage. ”

【推荐1】When I first met George, I was in my early 30s, seeking a creative outlet (出路) unrelated to boring housework and raising little ones. My children, then aged three and five, were just entering kindergarten and school life. At 65, George had recently retired and was seeking a rewarding hobby. For both of us, painting was ‘it’ and we met at a local painting class. Thus began a friendship that was to last until the day he died.
George arrived in Australia as an immigrant from Britain with his wife and two children. He worked hard, played hard, and had an opinion about everything. He adored his wife, his family, and his friends. A slim and energetic man, George took pride in his fitness and walked three kilometres every day.
As the only male in a painting class full of women, George ruled the roost and we were his hens. He adored his singular role and looked after his brood (一窝雏鸡) with the same attention he gave to everything.
He took to painting with great passion, even transforming the spare bedroom into a studio. A studio! His painting equipment was comprehensive. Ever practical, George housed many of these items in a red metal tool box.
After the completion of the course, we still kept in touch. One day when George was about 80 years old, he asked me to come to his house. George explained that he was giving up painting because of his illness and he gave away all his ‘stuff’ to me.
I still use much of his equipment today. The most treasured thing is the red tool box. The original shop sticker is still firmly in place although the price has long since worn off. But that’s all right because to my mind friendship is beyond price.

【推荐2】Glenn Cunningham and his brother were in charge of heating the classroom at school before the teachers and other students would arrive. But disaster struck one day when someone accidentally poured gasoline in a container and an explosion took place.
“When they looked at my legs the doctors thought they should amputate(截肢) my legs because they said if I got an infection I would not only lose my leg, but also lose my life," he is quoted as saying in the book American Miler: The Life and Times of Glenn Cunningham. “Even though the doctors said I'd never walk, they couldn't convince me because I knew I was going to be able to walk again.”
Creams and massages (按摩) aided his recovery but it was over a year before he could walk again. “My family was wonderful,” he said. “I had lost all the flesh on my knees. Yet my family kept changing the dressings and massaging my legs, though there was little muscle left to massage. Even after I was able to stand, holding onto either the bed or a chair, a neighbor kid said, ‘Aw, you are never gonna walk again!’ But by then I knew that nothing was going to stop me.”
His talent shone through early when just at 12 years of age, he had defeated all the runners in high school. During his senior year in high school, he created a new state record for the mile: clocking 4:28.3 in Manhattan. During the 1930s, he won two National Collegiate Athletic Association titles.
Having built a reputation as one of the finest runners in his country, Cunningham would go on to compete in the 1,500-meter event at the 1932 Olympics. He narrowly missed out on a medal as he finished fourth. Cunningham was at his peak by the time he made his second Olympic appearance at Berlin in 1936. He did not disappoint, setting a new US record at the event by clocking 3: 48. 4 but fell short of New Zealand's Jack Lovelock.
From being almost crippled (跛的)as a child to creating world records and going on to win a medal at the Olympics, Cunningham's career remains an inspiration for athletes.

【推荐3】One night, Pilar was in a deep sleep when she was woken by her cat Inti. Inti was meowing wildly outside Pilar's bedroom and throwing himself against the closed bedroom door. When Pilar opened her eyes, she saw that her bedroom was filled with smoke. As she escaped her house with Inti in her arms, she saw that a fire was burning in her kitchen. Pilar could easily have lost her life, but Inti would not let that happen. Even though Inti could have escaped the house through a cat door, he wouldn't leave Pilar.
As amazing as this story is, it is not as uncommon as you may think. Take the example of Charlotte Lee and her horse, Thunder. One summer night, the whole family was asleep with the windows open. It was normally very quiet where they lived. Suddenly, there was a loud noise. Charlotte woke up from her sweet dream, and the noise continued. Then she heard a horse running fast towards the house. The next thing she saw was Thunder standing outside her window, neighing and shaking his head. She knew something was wrong. Charlotte quickly got everyone out of the house before the earthquake hit. Thunder has saved her life.
There are also stories of wild animals coming to the rescue of humans. One animal known to be a friend of humans is the dolphin. Once, Todd Endris was surfing with his friends when he was attacked by a 13foot (4meter) shark. In the middle of the attack, a group of dolphins came to his rescue by forming a protective ring around Endris until he could get safely to shore. Without the help of the dolphins, there is little chance that Todd could have escaped.
No one is sure why animals have so often come to our rescue. However, it is clear that humans and animals enjoy a close relationship. It is important that we care for them as much as we can.

"Move out of the way!" I shouted.
She walked away sadly. But I didn't feel like I had to apologize to her.
While I was in bed that evening, my husband said to me, "While dealing with a stranger, you were polite, but with a daughter you love, you were unkind. Your daughter brought you some flowers that she picked herself this afternoon. You'll find them in the kitchen by the door. Have you seen the tears in her eyes?"
I quietly went and knelt down by my daughter's bed.
"Honey, I am so sorry, "I said. "Are these the flowers you picked for me?"
She said, "I found them by the tree. I picked them because they're pretty like you. I knew you'd like them, especially the blue ones."
I tearfully replied, "Sweetie, I'm really sorry for the way I acted today. I shouldn't have shouted at you",
"It's okay. I love you anyway, "she said as she kissed me on my cheek.

【推荐2】When we're in need, we always turn to our parents for help. But would you like them to hear the conversations you have with your friends on the school playground or lunch queue? Social networking sites have become extensions (延伸)of the school hallways, so would you add your parents as "friends" and allow them to view your online activities and conversations with friends？
In the past the generation gap included a technology gap, where children were up to date with the latest technology and parents were left behind, content to continue their day-to-day lives as they always had because they had no need to know more about technology. However, more and more parents are beginning to realize just how important social networks are in their lives. This realization has given many parents the motivation to educate themselves about social networking sites.
These days many people are attracted to social networking sites because they can choose who they have around them; there's also a certain amount of control over privacy(隐私) that we don't get in real life. Sometimes we feel that privacy is violated when we must accept a "friend" request from a parent or family member.
It's a difficult choice whether or not to allow a parent to become a part of our online lives. On the one hand we don't want to "reject" their request because that might hurt their feelings or make them feel you have something to hide. On the other hand if you do accept, then you could have a sense of being watched and no longer feel free to comment or communicate the way you did before.
A recent survey suggested that parents shouldn't take it personally if their children overlook their requests. When a teenager overlooks a parent's friend request, it doesn't necessarily mean that he/she is hiding something, but it could mean that this is one part of his/her life where he/she wants to be independent.
Perhaps talking with parents and explaining would help soften the blow if you do choose not to add them to your friend list.

Bad news sells. If it bleeds, it leads. No news is good news, and good news is no news. Those are the classic rules for the evening broadcasts and the morning papers. But now that information is being spread and monitored(监控) in different ways, researchers are discovering new rules. By tracking people’s e-mails and online posts, scientists have found that good news can spread faster and farther than disasters and sob stories.
“The ‘if it bleeds’ rule works for mass media,” says Jonah Berger, a scholar at the University of Pennsylvania. “They want your eyeballs and don’t care how you’re feeling. But when you share a story with your friends, you care a lot more how they react. You don’t want them to think of you as a Debbie Downer.”
Researchers analyzing word-of-mouth communication—e-mails, Web posts and reviews, face-to-face conversations—found that it tended to be more positive than negative(消极的), but that didn’t necessarily mean people preferred positive news. Was positive news shared more often simply because people experienced more good things than bad things? To test for that possibility, Dr. Berger looked at how people spread a particular set of news stories: thousands of articles on The New York Times’ website. He and a Penn colleague analyzed the “most e-mailed” list for six months. One of his first findings was that articles in the science section were much more likely to make the list than non-science articles. He found that science amazed Times’ readers and made them want to share this positive feeling with others.
Readers also tended to share articles that were exciting or funny, or that inspired negative feelings like anger or anxiety, but not articles that left them merely sad. They needed to be aroused(激发) one way or the other, and they preferred good news to bad. The more positive an article, the more likely it was to be shared, as Dr. Berger explains in his new book, “Contagious: Why Things Catch On.”
