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

Then he discovered that an old friend of his was one of the members of the jury at his trial. Of course, he did not tell anybody, but he managed to see his friend secretly one day. He said to him, "Jim, I know that the jury will find me guilty of having stolen the money. I cannot hope to be found not guilty of taking it—that would be too much to expect. But I should be grateful to you for the rest of my life if you could persuade the other members of the jury to add a strong recommendation for mercy to their statement that they consider me guilty." "Well, George," answered Jim, "I shall certainly try to do what I can for you as an old friend, but of course I cannot promise anything. The other 11 people on the jury look terribly strong-minded to me." George said that he would quite understand if Jim was not able to do anything for him, and thanked him warmly for agreeing to help. The trial went on, and at last the time came for the jury to decide whether George was guilty or not. It took them five hours, but in the end they found George guilty, with a strong recommendation for mercy. Of course, George was very pleased, but he did not have a chance to see Jim for some time after the trial. At last, however, Jim visited him in prison, and George thanked him warmly and asked him how he had managed to persuade the other members of the jury to recommend mercy. "Well, George," Jim answered, "as I thought, those 11 men were very difficult to persuade, but I managed in the end by tiring them out. Do you know, those fools had all wanted to find you not guilty!" Question : What did George manage to do when his trial was about to begin？ (33) A．Decided that he would plead guilty. B．Told another prisoner about his old friend. C．Succeeded in seeing his friend secretly one day. D．Told his family about his old friends.

A．skating in the French Alps B．skating in the German Alps C．skiing in the French Alps D．skiing in the German Alps

Marshall was actually in a hiding-place. Using his mobile (移动的) phone, he got himself connected with the White House. He told the Vice President not to talk with the terrorists in spite :of the killing. At the same time he killed one of the terrorists and at last helped most of the hostages (人质) to escape using parachutes (something for making people fall slowly and safely from a plane). However, Ivan was still holding his wife and daughter. Rather than see either killed , Moscow to set General Radek free. He and Ivan fought it out and at last Ivan was killed. Marshall rang Moscow just in time to prevent Raded getting away. He had his family succeeded in escaping at last but the plane crashed into the sea. James Marshall didn't know what had happened to the plane until ______. A．he boarded Air Force One B．the six Russian journalists interviewed him C．the plane was hijacked D．he escaped in a special emergency pod

In January, the University of Illinois-Chicago junior was charged with drunken driving. He pleaded guilty to a misdemeanor (轻罪), paid a fine and got court supervision, but that brought him to the attention of immigration officials and triggered deportation proceedings. "It was one mistake in my life," he says. Padilla's impending deportation, catapulted (猛投) him into a campaign to stop the deportation of college students and recent graduates. Lawmakers, students, members of the clergy and other acti-vists hope to buy the students time and use their stories to push for laws that would allow them, and perhaps millions of other illegal immigrants, to earn legal status, says Joshua Hoyt of the Illinois Coalition for Immigrant and Refugee Rights. Immigration and Customs Enforcement (ICE) agreed last week to delay Padilla's deportation for a year, making him one of at least seven young illegal immigrants who have had their deportations delayed since June, according to Dream Activist, one of the groups spearheading the campaign. Family ties and community standing are among the factors ICE considers when asked to delay a deportation, says ICE spokesman Richard Rocha. "I want to graduate college and give back to this country," Padilla says. His supporters flooded the Department of Homeland Security with thousands of faxes and designed a Facebook page telling 2 800 members how to help. The Chicago City Council passed a resolution in his behalf, and Rep. Jan Schakowsky, D-Ill. , introduced a bill specifically for him that would allow him to stay. "Why would we deprive ourselves of outstanding students and future leaders？" she asks. "They had no part in the decision to come here. " There are 12 million illegal immigrants in the USA. Activists call for an overhaul of immigration law that would offer them a way to earn legal status. Rep. Luis Gutierrez, Dill. , introduced a bill Tuesday that would give illegal immigrants who pay fines, pass background checks and meet other requirements a path toward legal residency. College students who are illegal immigrants fail under a separate proposal called the Development, Relief and Education for Alien Minors Act--the DREAM Act. Requirements would include arrival in the USA at 15 or younger, a five-year residency or more, and at least two years of college or military service. Versions of the act have been introduced since 2001 without success. Padilla could be deported because ______. A．he was charged with drunken driving B．he had no Social Security number C．he did not get the financial aid in the college D．he was an illegal in,migrant

A．informing B．informed C．to be informed D．to inform
