单选题The young people who talk of the village as being "dead" are talking nothing but nonsense, as in their hearts they must surely know. No, the village is not dead. There is more life in it now than there ever was. But it seems that "village life" is dead. Gone for ever. It began to decline about a hundred years ago. When many girls left home to go into service in town many miles away, and men also left home in increasing numbers in search of work, and home was where work was. There are still a number of people alive today who can remember what "village life" meant in the early years of the present century. It meant finding your entertainment in the village of within walking distance of it. It meant housewives tied to the home all day and every day. It meant going to bed early to save lamp-oil and coal. Then came the First World War and the Second World War. After each war, new ideas, new attitudes, new trades and occupations were revealed to villagers. The long-established order of society was no longer taken for granted. Electricity and the motorcar were steadily operating to make "village life" and "town life" almost alike. Now with the highly-developed science and technology and high-level social welfare for all, there is no point whatever in talking any longer about "village life." It is just a life, and a better life. Finally, if we have any doubts about the future, or about the many changes which we have seen in our lives, we have only to look in at the school playground any mid-morning; or see the children as they walk homeward in little groups. Obviously the children are better fed, better clothed, better educated, healthier, prettier and happier than any generation of children that ever before walked the village street.

单选题The biggest safety threat facing airlines today may not be a terrorist with a gun, but the man with the portable computer in business class. In the last 15 years, pilots have reported well over 100 incidents that could have been caused by electromagnetic interference. The source of this interference remains unconfirmed, but increasingly, experts are pointing the blame at portable electronic devices such as portable computers, radio and cassette players and mobile telephones. RTCA, an organization which advises the aviation (航空) industry, has recommended that all airlines ban(禁止)such devices from being used during "critical" stages of flight particularly take- off and landing. Some experts have gone further, calling for a total ban during all flights. (76) Currently, rules on using these devices are left up to individual airlines. And although some airlines prohibit passengers from using such equipment during take- off and landing, most are reluctant to enforce a total ban, given that many passengers want to work during flights. The difficulty is predicting how electromagnetic riel& might affect all aircraft's computers. (77)Experts know that portable devices emit radiation which affects those wavelengths which aircraft use for navigation and communication. But, because they have not been able to reproduce these effects in a laboratory, they have no way of knowing whether the interference might be dangerous or not. The fact that aircraft may be vulnerable(易受损的)to interference raises the risk that terrorists may use radio systems in order to damage navigation equipment. (78) As worrying, though, is the passenger who can't hear the instructions to turn off his radio because the music's too loud.
