单选题The speaker made the point that, although there were many good reasons in favour of equality for women in all spheres, and particularly perhaps in the sphere of political activity where they needed a voice, and above all needed to be able to influence others on their behalf, there were reasons against this as matters stood at the present time. He was asked whether any matters, regardless of how far they seemed to be in the interests of government and leaving aside the question of the popularity or otherwise of the move, could be more important than the liberty of a large section of the population of what was a so-called "free" country. He replied that he had repeated before that the moral issue was a clear one; however, emotional appeals and the use of words like "freedom" and "justice" avoided the most practical aspect of the affair. No government in its senses, however enlightened its leaders, however large its majority, however secure in the favour of the people was going to be able to introduce a motion such as "Votes for Women" without considerable controversy flaring up. How much less were they going to be able to introduce it with a government on the brink of falling, the nation on the edge of war and the country radically opposed to any move which would seem to the electorate to threaten the long established traditions of the British way of life.

单选题Parents can easily come down with an acute case of schizophrenia from reading the contradictory reports about the state of the public schools. One set of experts asserts that the schools are better than they have been for years. Others say that the schools are in terrible shape and are responsible for every national problem from urban poverty to the trade deficit. One group of experts looks primarily at such indicators as test scores, and they cheer what they see: all the indicators — reading scores, minimum competency test results, the Scholastic Aptitude Test scores — are up, some by substantial margins. Students are required to take more academic courses — more mathematics and science, along with greater stress on basic skills, including knowledge of computers. More than 40 state legislatures have mandated such changes. But in the eyes of another set of school reformers such changes are at best superficial and at worst counterproductive. These experts say that merely toughening requirements, without either improving the quality of instruction or, even more important, changing the way schools are organized and children are taught makes the schools worse rather than better. They challenge the nature of the tests, mostly multiple choice or true or false, by which children's progress is measured; they charge that raising the test scores by drilling pupils to come up with the right answers does not improve knowledge, understanding and the capacity to think logically and independently. In addition, these critics fear that the get-tough approach to school reform will cause more of the youngsters at the bottom to give up and drop out. This, they say, may improve national scores but drain even further the nation's pool of educated people. The way to cut through the confusion is to understand the different yardsticks used by different observers. Compared with what schools used to be like "in the good old days", with lots of drill and uniform requirements and the expectation that many youngsters who could not make it would drop out and find their way into unskilled jobs by those yardsticks the schools have measurably improved in recent years. But by the yardsticks of those experts who believe that the old schools was deficient in teaching the skills needed in the modern world, today's schools have not become better. These educators believe that rigid new mandates may actually have made the schools worse.

单选题Competition for admission to the country"s top private schools has always been tough, but this year Elisabeth realized it had reached a new level. Her wake-up call came when a man called the Dalton School in Manhattan, where Elisabeth is admissions director, and inquired about the age cutoff for their kindergarten program. After providing the information, she asked about the age of his child. The man paused for an uncomfortably long time before answering. "Well, we don"t have a child yet. We"re trying to figure out when to conceive a child so the birthday is not a problem." Worries are spreading from Manhattan to the rest of the country. Precise current data on private schools are unavailable, but interviews with representatives of independent school all told the same story: an oversupply of applicants, higher rejection rates. "We have people calling us for spots two years down the road," said Marilyn of the Seven Hills School in Cincinnati. "We have grandparents calling for pregnant daughters." Public opinion polls indicate that Americans" No.1 concern is education. Now that the long economic boom has given parents more disposable income, many, are turning to private schools, even at price tags of well over $10,000 a year. "we"re getting applicants from a broader area geographically than we ever have in the past," said Betsy of the Latin School of Chicago, which experienced a 20 percent increase in applications this year. The problem for the applicants is that while demand has increased, supply has not. "Every year, there are a few children who do not find places, but this year, for the first time that I know of, there are a significant number without places," said Elisabeth. So what can parents do to give their 4-year-old an edge? Schools know there is no easy way to pick a class when children are so young. Many schools give preference to children of their graduates. Some make the choice by drawing lots. But most rely on a mix of subjective and objective measures: tests that at best identify developmental maturity and cognitive potential, interviews with parents and observation of applicants in classroom settings. They also want a diverse mix. Children may end up on a waiting list simply because their birthdays fall at the wrong time of year, or because too many applicants were boys. The worst thing a patent can do is to pressure preschoolers to perform—for example, by pushing them to read or do math exercises before they"re ready. Instead, the experts say, parents should take a breath and look for alternatives. Another year in preschool may be all that"s needed.
