Most previous international gatherings on this subject have not seen the same intensity of delegate inter est. Many nations have gone through a shock of recognition. A decade ago, only those nations identified as "producing countries" also become "consuming countries", but many have witnessed the growth within their borders of drug trafficking gangs (often allied with terrorists) so powerful they present a danger to the state's stability. Many developing countries now have the worst of both worlds, in that they grow their own people. There is a growing sense of fright in ninny governments that matters are out of control and the single way to recover is through cooperation with other countries. The high points of the conference were the drafting of two documents, both of which were adopted with out a disagreed vote. One was a joint declaration of intent to combat drag abuse and traffic. The other consisted of many detailed suggestions for particular regional and national policies. Overall, the conference developed a two-level action plan. The focus was on ways to curb the demand for dangerous drugs and on methods of destroying at least interrupting the distribution process. On the demand side, the delegates recommended the establishment of a system for collecting information on the nature and scope of narcotics use. In addition, they concluded that drug education should be taught in schools and that governments and labor organizations should act together in the anti-drug campaign in the work place. The delegates also recommended strict adherence to international agreements to curb the supply of narcotics. The United Nations Conference was held to discuss ______. A．ideological and individual differences B．production C．drug abuse D．nations of file world

Florida's E-school attracts many students who need flexible scheduling, from young tennis stars and young musicians to brothers Tobias and Tyler Heeb, who take turns working on the computer while helping out. with their family's clam-farming business on Pine Island, off Florida's southwest coast. Home-schoolers also are well represented. Most students live in Florida, but 55 hail from West Virginia, where a severe teacher shortage makes it hard for many students to take advanced classes. Seven kids from Texas and four from Shanghai round out the student body. The great majority of Florida Virtual Schoolers—80 percent—are enrolled in regular Florida public or private high schools. Some are busy overachievers. Others are retaking classes they barely passed the first time. The school's biggest challenge is making sure that students aren't left to sink or swim on their own. After the school experienced a disappointing course completion rate of just 50 percent in its early years,Executive Director Julie Young made a priority out of what she calls "relationship-building," asking teachers to stay in frequent E-mail and phone contact with their students. That personal touch has helped. The completion rate is now 80 percent. Critics of online classes say that while they may have a limited place, they are a poor substitute for the face-to-face contact and socialization that take place in brick-and-mortar classrooms. Despite opportunities for online chats, some virtual students say they'd prefer to have more interaction with their peers. Students and parents are quick to acknowledge that virtual schooling isn't for everyone. "If your child's not focused and motivated, I can only imagine it would be a nightmare," says Patricia Haygood of Orlando, whose two daughters are thriving at the Florida school. For those who have what it takes, however, virtual learning fills an important niche. "I can work at my own pace, on my own time," says Hackney. "It's the ultimate in student responsibility." Kimberly Rugh Talked about her son's birthday party ______ . A．with her friends B．with her colleagues C．in the classroom D．in an E-mail massage sent to her students

Revising can be described as the most important(and frequently most neglected) part of writing. Novelists Doris Lessing has said that many novels miss greatness because authors are unwilling or unable to revise them. James Michener explains the importance of revision this way: "I have never thought of myself as a good writer. Anyone who wants reassurance of that should read one of my first drafts. But I' m one of the world' s great revisers." Revising takes many forms. It means thinking about the audience for your writing. Who will read your work and why？ It also means developing an overall plan for the writing that will make your ideas clear. Often the organization of a first draft will reflect your process of discovery, but that may not be the best way to present your ideas to someone else. Revising also gives attention to the style. of language, to the structure of a paragraph, and to the shape of sentences and other forms that show learning to its best advantage. Writing to learn and writing to show learning are never, of course, entirely separate processes. Writers frequently consider issues of demonstrating learning while writing to learn, and writing to show learning often leads to new under- standings. In drafting, for example, you may start thinking about what an audience will need to know in order to under- stand your point and change a word or a phrase to make your meaning clearer. But understanding the differences between writing to learn and writing to show learning is central to seeing writing as a process. What Doris Lessing said helps to support the idea that______. A．he is one of the world' s great revisers B．he is not a good writer C．revising is very important D．many writers are unwilling to revise their works
