Living in Brazil (巴西)and Switzerland
Moving to a different city may seem difficult. You have to change schools and get used to your new home. But you can always go back to that city to visit. When you move to another country, things are different. However, difficult as it may be, the experience can be rewarding.
My dad, a Brazilian, is really funny and can make friends quickly. My mom, a Swiss, is usually quiet and a bit shy. She likes to be organized, But my dad never makes plans. She enjoys staying home, but my dad always wants to go out. Swiss and Brazilian一what a mix!
After my parents got married, they moved to Switzerland. There they had my brother and me. When I was two, we moved to Brazil. During my childhood we visited Switzerland every year.
Many people ask me where I prefer to live: Brazil or Switzerland. It's really hard to answer because I love both countries. Brazil is a big country with many states and people. There are multiple dialects and many types of foods. People here have beautiful smiles and are always happy, even if they are poor. In the south the climate is cool, but in the north It's hot and humid.
Switzerland, on the other hand, is small but beautiful and clean. There are four languages in that tiny country. People there are very different from Brazilians: they are wealthy, independent, and organized. The food is delicious, and of course, the famous Swiss chocolate is great, and the climate is dry and cool.
I love both countries. In Switzerland, it's pleasant, calm, and peaceful everywhere. I enjoyed my stay there very much. But now I am happy here in Brazil. I feel excited and at home.

Tim Berners-Lee is the man who wrote the software(软件)programme that led to the foundation of the World Wide Web. Britain played an important part in developing the first generation of computers. The parents of Tim Berners-Lee both worked on one of the earliest commercial(商业的)computers and talked about their work at home. As a child he would build models of computers from packaging material. After graduating from Oxford University he went on to the real thing. In the 1980s scientists were already communicating using a primitive version(原始版本)of e-mail. While working at a laboratory in Switzerland, Tim Berners-Lee wrote a programme, which let him store these messages. This gave him another idea: write a programme that will let academics(学术界人士)from across the world share information on a single place. In 1990 he wrote the HTTP(服务程序所用的协议)and HTML(超文本链接标示语言)programmes which form. the basis of the World Wide Web.
The next year his programmes were placed on to the Internet. Everyone was welcome to use them and improve them if they could. Programmers used his codes(编码)to work with different operating systems. New things like web browsers(浏览器)and search engines were developed. Between 1991 and 1994 the number of web pages rose from 10 to 100,000.
In 1994 Tim Berners-Lee formed the newly formed World Wide Web Consortium(协会),or W3C. More than 200 leading companies and laboratories are represented(代表)by W3C. Together they make sure that everyone can share equally on the web. "The Web can help people understand the way that others live and love and are human. It helps us understand the humanity of people, "he says.

More than 40 years passed before physicists were able to offer an explanation for superconductivity. The accepted theory, developed in the 1950s, holds that the fundamental behavior. of electrons changes at very low temperatures because of the effects of quantum mechanics. Electrons are tiny particles that make up the outer part of an atom, circling rapidly around the nucleus of the atom. In a regular conductor—a metal that conducts an electric current—the outermost electrons are not bound tightly to the atoms, and so they move around relatively freely. The flow of these electrons is an electric current.
At normal temperatures, a conductor's electrons cannot move completely freely through the metal because they are "bumped around" by the metal's atoms. But according to the leading theory of superconductivity, when a metal is very cold, electrons form. pairs. Then, like couples maneuvering on a crowded dance floor but never colliding, the paired electrons are able to move unimpeded through the metal. In pairing up, it seems, the electrons are able to "blend together" and move in unison without resistance. This explanation seems to account for superconductivity at extremely low temperatures, but in 1986 scientists in Switzerland found that some metal-containing ceramics are superconductors at much higher temperatures. By 1992, scientists had developed ceramics that become superconducting at - 297'F, and some researchers speculated that room-temperature superconductors may be possible. Scientists are still trying to formulate a theory for high-temperature superconductivity.
The new ceramic materials can be maintained at their superconducting temperatures, with relatively inexpensive liquid nitrogen rather than the much colder and much more costly liquid helium required by metal superconductors. The cost difference could make superconductivity practical for many new technologies. For example, magnetically levitated trains, which require superconducting electromagnets, would be much cheaper to build than they are now. Superconducting devices might also be used for advanced power transmission lines and in new types of compact, ultrafast computers. But for the time being, superconductivity is finding application mostly in scientific research and in some kinds of medical imaging devices.
The flow of an electric current in a regular conductor is made possible by the fact that______.
A.electrons circle rapidly around the atom
B.the outermost electron move relatively freely around the atom
C.the innermost electrons stick to the atom
D.the outermost electrons are bound tightly to the inner ones
