单选题Facebook Wants to "Listen" to Your Music and TV Facebook is to release a new feature on its mobile app that "listens" to your music and TV shows. If the song or show is recognized by the app, users can publish the information on their profile or to selected friends. The service hopes to take advantage of the "second screen" trend, which sees fans of TV shows in particular sharing their experiences on social networks. However, some users have privacy concerns. The feature, which will be available in a few weeks" time, uses the microphones inside users" smartphones to detect nearby music or TV shows. As the user begins writing a status update, a small animated icon will appear at the top of the app. If the app detects the appropriate audio signals and finds a match from its database, the user can then share what he or she is watching or listening to. Facebook says the feature can be turned off at any time, the audio recording is not stored anywhere and the device cannot identify background noise or conversations. "If you share music, your friends can see a 30-second preview of the song. For TV shows, the story in News Feed will highlight the specific season and episode you"re watching," Facebook said in a statement. The company hopes this new method of sharing user listening and watching habits will take advantage of the five billion status updates related to TV and music experiences that the social networking giant sees on a yearly basis. However, automating part of the sharing process has left some users suspicious, with Nicole Simon commenting on TechCrunch that: "While the idea is nice and technology really interesting, I have no interest in Facebook "observing" my audio and surrounding. Yes, it starts currently as opt-in, and only on occasion, but there is no trust from my side for even that." The BBC understands that this new feature was not specifically designed to enhance Facebook"s advertising. However, the company could push an advertisement to a user"s phone based on their tracked listening habits. This is in keeping with Facebook"s current approach to advertising, which uses publicly provided information on users" profiles to push advertisements that are more relevant to each individual user. The basic idea behind Facebook"s feature is not a new one—since 2002 Shazam, which has recently seen a $3 million investment from Sony Music Entertainment, has been providing a similar audio recognition service, with its website describing itself as "a mobile app that recognizes music and TV around you". Facebook"s much larger user base could pose a future threat to the comparatively smaller company.

单选题{{B}}第二篇{{/B}} {{B}}Investment and Consumption{{/B}} Investment in the public sector, such as electricity, irrigation, public services and transport (excluding vehicles, ships and planes) increased by about 10%, although the emphasis moved to the transport and away from the other sectors mentioned. Trade and services recorded a 16% ~ 17% investment growth, including a 30% increase in investment in business premises. Industrial investment is estimated to have risen by 8%. Although the share of agriculture in total gross investment in the economy continued to decline, investment grew by 9% in absolute equipment. Housing construction had 12% more invested in it in 1964, not so much owing to increased demand, as to fears of new taxes and limitation of building. Total consumption in real terms rose by close on 11% during 1964, and per capita personal consumption by under 7%, as in 1963. The undesirable trend towards a rapid rise in consumption, evident in previous years, remained unaltered. Since at current prices consumption rose by 16% and disposable income by 13%, there was evidently a fall in the rate of saving in the private sector of the economy. Once again consumption patterns indicated a swift advance in the standard of living. Expenditure on food declined in significance, although consumption of fruit increased. Spending on furniture and household equipment, health, education and recreation continued to increase. The greatest proof of altered living standards was the rapid expansion of expenditure on transport (including private cars) and personal services of all kinds, which occurred during 1964. The progressive wealth of large sectors of the public was demonstrated by the changing composition of durable goods purchased. Saturation (饱和) point was rapidly being approached for items such as the first household radio, gas cookers, and electric refrigerators, whereas increasing purchases of automobiles and television sets were registered.

单选题阅读下面这篇短文，短文后列出7个句子，请根据短文的内容对每个句子做出判断。 {{B}}Sleeping{{/B}} People who sleep for more than eight hours a night do not live as long as those who sleep for six hours, according to the biggest study yet into sleep patterns and mortality (死亡率). Scientists have no explanation for the findings and do not know if they mean people who like a lie-in (睡懒觉) can extend their lives by sleeping less. Although it is a common belief that sleeping for at least eight hours a night is vital for health and well-being, the six-year study involving more than 1.1 million Americans older than 30 found that those who slept for less than eight hours were far from doing themselves any long-term harm. “Individuals who now average 6.5 hours of sleep a night can be reassured that this is a safe amount of sleep. From a health standpoint, there is no reason to sleep longer,” said Daniel Kripke, a professor of psychiatry (精神病学) at the University of California, San Diego. Dr. Kripke said, “We don’t know if long sleep periods lead to death. Additional studies are needed to determine if setting your alarm clock earlier will actually improve your health.” The scientists, who were funded by the American Cancer Society, found that the best survival rates were among the men and women who slept for seven hours a night. Those who slept for eight hours were 12 per cent more likely to die during the six-year period of the study, when other factors such as diet and smoking were taken into account. Even those who spent a mere five hours a night in bed lived longer than those who slept for eight or more hours. However, an increasing death rate was found among those who slept for less than five hours. Dr. Kripke said, “Previous sleep studies have indicated that both short and long duration (持续时间) sleep had higher mortality rates. However, none of those studies were large enough to distinguish the difference between seven and eight hours a night, until now.”
