[单项选择] The estimates of the numbers of home-schooled children vary widely. The U.S. Department of Education estimates there are 250,000 to 350,000 home-schooled children in the country. Home-school advocates put the number much higher — at about a million.
Many public school advocates take a harsh attitude toward home-schoolers, perceiving their actions as. the ultimate slap in the face for public education and a damaging move for the children. Home-schoolers harbor few kind words for public schools, charging shortcomings that range from lack of religious perspective in the curriculum to a herdlike approach to teaching children.
Yet, as public school officials realize they stand little to gain by remaining hostile to the home-school population, and as home-schoolers realize they can reap benefits from public schools, these hard lines seem to be softening a bit. Public schools and home-schoolers have moved closer to tolerance and, in some cases, even cooperation.
Says John M

[单项选择]International airlines have rediscovered the business travelers, the man or woman who regularly jets from country to country as part of the job. This does not necessarily mean that airlines ever abandoned their business travelers. Indeed, companies like Lufthansa and Swissair would tightly argue that they have always catered best for the executive class passengers. But many lines could be accused of concentrating too heavily recently on attracting passengers by volume, often at the expense of regular travelers. Too often, they have seemed geared for quantity rather than quality.
Operating a major airline in the 1980s is essentially a matter of finding the right mix of passengers. The airlines need to fill up the back end of their wide-bodied jets with low fare passengers, without forgetting that the front end should be filled with people who pay substantially more for their tickets.
It is no coincidence that the two major airline bankruptcies in 1982 were among the compan
