Most dictionaries will tell you a number of (21) about a language. There are three things in particular that (22) important. These three things are spelling, pronunciation, and meanings. The first and most obvious thing is that a dictionary will (23) you the spelling of a word. If you're not sure about the spelling of a word, you can try to find the correct spelling in a dictionary. Words are listed in alphabetical order--a, b, e, and so on. For example, on a dictionary page the word "poor"--p, o, o, r--comes before "poverty"--p, o, v, e, r, t, y and the word "poverty" comes (24) the word "power"--p, o, w, e, r. The words are always given in alphabetical order. The second thing a dictionary will tell you is (25) . Most dictionaries give the pronunciation of a word in a special kind of alphabet. This special alphabet is called a phonetic, or sound alphabet. The phonetic spelling will tell you generally (26) a word is pronounced. There are a few different phonetic alphabets. Many dictionaries use the International Phonetic Alphabet to show pronunciation. The (27) thing a dictionary will tell you is the meanings of words. You can (28) a word and find out what it means. Many words have more than one meaning, and a good dictionary will explain all of the word's meanings. For example, in English the common word "get" has over 20 different meanings. The meaning, of course, (29) the sentence in which the word is used. These three things--spelling, pronunciation, and meanings--are some of the important (30) that you learn from dictionaries. 21.

Computers, which once only remembered data, will make more decisions. Machines that today tell doctors what symptoms the patients have may soon be recommending whether or not to perform. surgery as well. Others will design new buildings after questioning buyers about their preferences. Increasingly, human thought processes and even values are being programmed into computers, according to Earl Joseph, president of a consulting firm. "Imagine machines which are smarter and more intelligent than humans and, with their embedded(植入的) initiative, can't wait to tell you about it," he says. In everyday life, the future will mean talking directly to computers without pushing buttons. Just tell a toaster, stove or other kitchen device what to do, and it will hear the message. The oven may even decide itself how long to cook the roast. Tell the television, "I want to watch Channel 12 at 8 p.m., but store the show for next week," and the job will be done. The computer will talk back, too. Already some soft-drink machines complain loudly if you don't deposit enough cash. At home, a bedside machine may someday tell you, "You forgot to turn off the basement light." Away from home, the automobile of the future will think for itself. Scientists predict that drivers will feed destinations into a computer that will then explain what route to take and even tell where parking spaces are available. A city's traffic-control system might instruct the car's computer how fast to go in heavy traffic and whether to change lanes. This passage mainly discusses ______. A．the history of computers B．the different functions of computers C．the computer in the 21st century D．scientific breakthroughs in the 21st century

A police spokesman said the devices were made safe by explosive experts in the Ardorn district, where a woman was shot in the leg and 13 police officers were injured during a second successive night of violence. Northern Ireland’s police chief had earlier called on community leaders to work together to end the violence. The violence has erupted sporadically throughout a summer of Sectarian tension in northern Belfast. Questions 20 and 21 are based on the following news. At the end of the news item, you will be given 20 seconds to answer the questions. Now listen to the news. 20. Altogether how many people were injured during the violence？ A.1. B.2. C.13. D.14.

A．impose sanctions on Iran. B．veto some resolutions. C．sign a new treaty with Russia. D．stop Iran"s uranium enrichment program.

They got it. We fed them loans, knowing that much of the money would disappear corruptly. We turned away from atrocity in Chechnya lest we weaken the new Russian state. But most important, we went weak in the knees on missile defense. The prospect of American antiballistic missiles upset the Russians. And upsetting the Russians was something we simply were not to do. The Russians cannot keep up with American technology. And they fear that an American missile shield will render obsolete their last remnant of greatness: their monster, nuclear-tipped missiles. So they insist that we adhere to a 1972 treaty signed with the defunct Soviet Union that prohibited either side from developing missile defenses. That the treaty is obsolete-it long predates the world of rogue states racing to acquire missile-launched weapons of mass destruction-does not concern the Russians. Withdraw from the treaty, they said, and you have destroyed the "strategic stability" on which the peace of the world depends. The Clinton Administration took that threat seriously-so seriously that for eight years it equivocated on building an American ABM system. Finally, President Clinton promised to decide by June 2000. Come June, he punted. Eight years, and no defense. But the bear was content. Bear contentment was never a high priority for Ronald Reagan. He offered a different model for dealing with the Russians. The 1980s model went by the name of peace through strength. But it was more than that. It was judicious but unapologetic unilateralism. It was willingness-in the face of threats and bluster from foreign adversaries and nervous apprehension from domestic critics-to do what the U.S. needed to do for its own security. Regardless. It was Reagan who famously proposed a missile shield, and even more famously refused to barter it away at the Reykjavik summit, an event many historians consider the turning point in the cold war. That marked the beginning of the Soviets' definitive realization that they were going to lose the arms race to the U.S.-and that neither threats nor cajoling would dissuade the U.S. from running it. This decade starts with a return to the unabashed unilateralism of the 1980s. It began last year with a speech by George W. Bush proposing that the U.S. build weapons to meet American needs-and not to accommodate the complaints or gain the agreement of other countries. For 40 years the U.S. would not cut its offensive nuclear missiles except in conjunction with Soviet cuts. Bush's refreshing question was: Why？ We don't need Rnssians cutting our offensive weapons through arms-control treaties. And we don't need Russians telling us whether or not to build defensive weapons. This was the genesis of the Bush Doctrine, now taking shape as the Administration takes power. Its motto is, we build to suit-ourselves. Accordingly, the President and the Secretary of Defense have been unequivocal about their determination to go ahead with a missile defense. They staked their claim. And what happened？ Did the sky fall, as the Clinton Russian experts warned？ On the contrary. Convinced at last of American seriousness, the Russians immediately acquiesced. After just one month of Bush, Moscow has come forward with its very own missile-defense plan. The fact that it is not well sketched out and that it is in part designed to split the U.S. off from Europe is beside the point. The Russians have responded, as did the Soviets before them, to American firmness. Faced with reality, they accommodate it. Who defines reality; there lies the difference between this Administration and the last. Clinton let Russian opposition define reality. Bush, like Reagan, understands that the U.S. can resha A．the Russians understood that they needed nurturing from their new American friends B．the Russians knew Americans will surely help them C．upsetting the Russians was something the Americans simply were not to do D．the Americans shouldn't worry about upsetting the Russians
