单选题BPassage 1/B 　　If the United Nations Security Council rushes to send inspectors back into Iraq on Baghdad's promise of cooperation and under the old rules, it will be playing a chump's game, one Saddam Hussein has won countless times. Once in a while, the inspectors will face delay, obstruction, bugging and a succession of manufactured crises. These will prompt familiar fights among the major powers over whether a particular Iraqi act constitutes a major violation. Soon the United Sates will declare the whole exercise a failure and invade Iraq.　　That is an outcome worth avoiding. For the United States, the costs of such a war include the death of soldiers, economic losses caused by the effect of soaring oil prices on a fragile stock market, the need to post tens of thousands of troops in Iraq for many years, lingering resentment among allies whose cooperation we need and the near certainty of creating legions of new terrorists who hate America. For the United Nations, the result would be a terrible defeat, an admission of weakness and its inability to impose its writ on a villain. For the world as a whole, the costs will include the deaths of innocent Iraqis, increased repression in Arab states coping with domestic political anger and possibly chaos in the region.　　That is the short list. The worst-case outcomes include an attack with biological weapons on Israel and on American troops at their weakest moment-as they assemble in the region-by, a man with nothing to lose. What would be the likely response by both countries, and with what long-term consequence?　　There is a credible alternative to these scenarios that is worth trying. It is a new system of coercive inspection to replace the game of cat and mouse that Mr. Hussein has perfected. The Security Council would create a powerful, American-led multinational military force, the inspection implementation force, that would enable the inspection teams to carry out "comply or else" inspections. If Iraq refused to accept, or obstructed the inspections, regime change (preferably under a United Nations mandate) Would be back on the table.

单选题How does it happen that children learn their mother tongue so well? When we compare them with adults learning a foreign language, we often find this interesting fact. A little child without knowledge or experience often succeeds in a complete mastery of the language; a grown-up person with fully developed mental powers, in most cases, may end up with a faulty and inexact command. What accounts for this difference? Despite other explanations, the real answer in my opinion lies partly in the child himself, partly in the behavior of the people around him. In the first place, the time of learning the mother tongue is the most favorable of all, namely, the first years of life. A child hears it spoken from morning till night and, what is more important, always in its genuine form, with the right pronunciation, right intonation, right use of words and right structure. He drinks in all the words and expressions which come to him in a fresh, ever-bubbling spring. There is no resistance: there is perfect assimilation. Then the child has, as it were, private lessons all the year round, while an adult language student has each week a limited number of hours which he generally shares with others. The child has another advantage: he hears the language in all possible situations, always accompanied by the right kind of gestures and facial expressions. Here there is nothing unnatural, such as is often found in language lessons in schools, when one talks about ice and snow in June or scorching heat in January. And what a child hears is generally what immediately interests him. Again and again, when his attempts at speech are successful, his desires are understood and fulfilled. Finally, though a child's "teachers" may not have been trained in language teaching, their relations with him are always close and personal. They take great pains to make their lessons easy.
