Marconi, an Italian inventor, who gave us the radio, probably didn’t know how much his great invention would have done for the world in the years to come. Radio has perhaps done as much as any other communication tool. Things of the world can be reported to people everywhere a few seconds after they happened. Travelers in out-of-the-way places, ships at sea, and even astronauts round the earth are able to keep in touch with each other by radio.
Television is another important invention. It lets us see as well as hear the actor. Since it was invented, TV has done a great deal in the life of people everywhere. Many programs are now televised on TV.
Perhaps the most modern invention is “Telstar”, a “star” moving round the earth. It makes it possible for the people all over the world to be closer than ever before. Now on TV a family in Chicago can watch a car race in Italy, a table tennis competition in Beijing or a volleyball match in Japan as these events are actually happening!

【推荐1】The Mayan number system appeared in the fourth century, which was about 1,000 years earlier than the time when the European number system was created. It is different from the Arabic number system with a base 10. The Mayan system had a base 20. This system is believed to have been used because the Mayans lived in such a warm area and there was hardly a need to wear shoes, 20 was the total number of fingers and toes, so the system was workable. Therefore, there were two important numbers in this system. Besides 20, the other important number is 5, which had a connection with the number of fingers and toes on one hand or foot.
The Mayan system used two symbols(符号). A dot (.)was used to mean the units(one to four)and a dash(—)meant five. The Mayans were also the first to create symbols of nothing(or zero). The most common symbol was that of a shell()but there were several other symbols(e.g. ahead). It is interesting to learn that with all of the great experts on Maths and scientists in ancient Greece and Rome, it was the Mayan Indians who came up with this symbol zero or nothing. Picture 1 is a form of different numbers and how they would have been written.
From further study, people found that the 360 day calendar(日历)also came from the Mayan. They actually used base 18 when they made the calendar. Each month included 20 days with 18 months in a year. This left five days at the end of the year which was month in itself, full of danger and bad luck. In this way, the Mayans had invented the 365 day calendar.

【推荐2】When I opened my e-mail the other day, Rachel, a pretty woman, appeared on my computer screen. She greeted me by name and started talking happily. Sometimes she stopped to smile at me or blow a kiss. It was cool, right? In fact, she was reading to me an e-mail from my brother John.
Rachel could be there because of a new technology called Facemail lets you send in a funny way. By using it, your e-mails can be read to the receiver by an attractive person or by a clown. You can download the software at www.Facemail.com without paying. Facemail faces are lively and they can simulate the emotions that you put in you text. For example, type in , and Rachel blows a kiss.
LifeFX, the company that developed the Facemail, is sure there are wide business uses. Why is e-business not so popular now? One of the reasons is that buying online has no human touch. But if you go to the Nike website, and the famous basketball star Michael Jordan greets you by name, serves you, and personally closes the sale, won’t you be happy? Also, if mom can’t be home when kids get back from school, she can leave a note with a voice and picture on the screen to tell them what there is to eat.
It’s true that Facemail makes life easy and fun, but it should be used with care. The clown looks lively and funny at first. But if you choose the clown, put a few rude words in an e-mail and add some angry emotions, you’re got a Psycho mail.

People started using mirrors a long time ago. The first mirrors used were natural mirrors such as reflection in water. The first man-made mirrors were made out of the rock. Later, people used different metals such as bronze(青铜) to make mirrors. Throughout history, different types of mirrors have been used in many different cultures at the same time.
The first glass mirror was invented by a German named Justus Von Liebig in 1835. He used a silvering(镀银) technique to produce the glass mirror. Today aluminum(铝) is the main metal used for mirror.
Today, mirrors come in shapes and sizes. They are used for different reasons. We usually start our days by looking into the mirror in the bathroom. We also use them often during the day to keep ourselves tidy.
Mirrors are important for cars, too. If cars don' t have mirrors, it's impossible to drive. This is because drivers can't see other cars coming. Of course, that would lead to many car accidents.
It is said that breaking a mirror causes seven years of bad luck. So, look after your mirrors well.

【推荐1】Jorge and Maria Ramirez and their six-year-old son are smiling and laughing as they watch the baby giant panda. They are at a zoo as part of a large crowd watching the baby panda learning to walk. Why are people so attracted by the baby giant panda? Cuteness is the answer.
Experts say the things we describe as “cute” share several qualities(品质). What make something cute is different from what makes something beautiful. People often describe pandas as cute, but they don’t usually say they are beautiful. A butterfly, on the other hand, may be beautiful but not cute. While we tend(倾向于)to admire(欣赏) beautiful things, we do not tend to have the fondness for them that cute things inspire (激发) in us.
Scientists have discovered some key facial features and behaviors that cute things have in common. Two important features are a round face and bright eyes. The position of the eyes is also important: the eyes should at least appear to face forward and not be high on the face. There are also certain behaviors that cute things have in common, such as walking and moving arms, legs and wings unsteadily. Other important qualities of cuteness include youth, innocence(天真)and neediness, as well as being vulnerable(脆弱的)to possible harm or danger.
The baby panda, with its round face, big black eyes and unsteady movements, has all the key features which add up to being cute. Another popular creature that shares many of these cute qualities is the baby emperor penguin. And many of people’s pets can be described as cute.
Scientists believe there is an important reason why we are attracted to all these cute qualities. It is because human babies have all these qualities. They have round faces, bright eyes and unsteady movements. Human babies cannot get by without help from adults. Scientists point out that the cuteness of babies makes adults want to take care of them. This allows babies to survive(存活), become adults and have their own babies. This cycle ensures the human species continues.
Advertisers use the special attraction of cute things in their attempts(企图,尝试) to get us to buy their products. In Japan, for example, one of the most popular images is Hello Kitty. Many cartoon animal characters have round faces and large, bright eyes that face forward. In the real world, ducks and mice do not have round faces, and their small eyes are on the side of their heads.
The Ramirez family is not aware (意识到的) of all of this. For now, they are too busy taking pictures and admiring the baby panda.

【推荐2】How do you feel when your teacher asks you to work on a group project with other students? Do you like to work together with others or work alone?
The Programme for International Student Assessment, or PISA, carried out a survey of students’ ability to work together in groups. They found that students who do well on tests by themselves are also likely to be better at working with other people. This finding was true for many countries. Students in Japan, South Korea, Finland and Canada, where test scores are high, also did well in working together to solve problems. But this is not the case for every country. Chinese students, who tend (倾向于) to have high scores as well, displayed just average collaborative (合作的) skills.
“One reason might be that Chinese parents and teachers focus too much on grades,” said Zhao Zhongxin, former vice president of the Chinese Family Education Association. “Students have a lot of exam pressure and they view school as a place for competition.” “However, collaborative skills are very important for preparing students for today’s society,” he added. Luckily, more Chinese parents and teachers are realizing the importance of this and are thinking of ways to help students improve these skills.
Another interesting finding from the PISA survey was that girls tend to be better than boys at working together. They said girls show more positive attitudes towards relationships, which means they are more willing to listen to others’ opinions.
PISA also found that the classroom environment tends to influence how well students collaborate. In classes where there are a lot of activities that require communication, such as class debates, students tend to have better attitudes toward collaborating.

【推荐3】If the population of the earth continues to increase , there will not be enough resources (资源) left to keep life on the planet. We will use up all the oil that drives our cars sooner or later .One possible way to work out the problem, has recently been suggested by an American scientist, Professor Carl Sagan.
Sagan believes that before the earth’s resources are completely used, it will be possible to change the atmosphere of Venus(金星) and create a new world almost as large as Earth itself. The difficulty is that Venus is much hotter than the earth and there is only a little water there.
Sagan suggests that algae organisms(海藻组织) can live in very hot or cold temperatures and at the same time produce oxygen. They should be bred(养殖) in conditions similar to those on Venus. When this has been done, In a short time, the algae will break down the carbon dioxide into oxygen and carbon.
When the algae have done their work, the atmosphere will become cooler, but before man can set foot on Venus it will be necessary for the oxygen to produce rain. The surface of the planet will still be too hot for man to land on but the rain will finally fall and in a few years something like earth will be reproduced on Venus.
1. The population growth on Earth will cause the lack(缺乏) of _________.A.food | B.oil | C.space | D.resources |
A.The shortage of the algae | B.The shortage of carbon |
C.The much hotter weather | D.The much cooler weather |
A.It can live in very hot temperatures. | B.It can live in very cold temperatures. |
C.It can break down the carbon dioxide. | D.It can provide enough food for man. |
