单选题 Babies cry to call attention to their immediate needs: food, or rest, or a diaper change or cuddles. But without intending to, crying babies might also provide insight into a defining trait that will develop later in life. As Matt Stevens of the New York Times reports, a new study has found that the pitch of a baby's cry could predict what he or she will sound like as an adult. Researchers in the U.K. and France wondered if vocal pitch might be determined even earlier than age seven—during infancy, perhaps, or even in the womb (子宫). To find out, the team recorded the cries of 15 French babies—six girls and nine boys, from two to five months old. Researchers then compared those recordings to recordings of the same children at age four or five. The team found that the pitch of babies' cries was a 'substantial predictor' of vocal pitch at four or five years of age. 'Differences in voice pitch,' the researchers conclude, 'may—at least partly—arise very early in life.' The authors of the study suggest that these differences might develop in the womb, when fetuses are exposed to varying levels of hormones. As Carl Engelking of Discover reports, the team also analyzed the children's 2D:4D digit ratio, or the ratio between the lengths of the index finger and the ring finger. Studies have suggested that this ratio can reveal how much testosterone (睾丸激素) a person was exposed to in the womb. Researchers found that 2D:4D digit ratio in the right hand correlated positively with differences in vocal frequency in both baby cries and children's speech (this is consistent with other studies showing that 2D:4D ratios are expressed more strongly in the right hand). In other words, as a statement announcing the new research explains, 'if the index finger on the right hand is longer than the ring finger, a baby will be likely to grow up to have a high-pitched voice. Conversely, if it is shorter, they will be more likely to have a lower-pitched voice.'

单选题The political crisis in Ukraine, where opposition protesters are burning campfires and setting up tents in the center of Kiev, is presenting a test for Russia, which gambled heavily on its neighbor"s presidential election. A defeat of the pro-Moscow candidate, Prime Minister Viktor Yanukovych, would humiliate the Kremlin one year after another former Soviet Republic, Georgia, slipped from its influence, according to observers and political analysts. The Ukrainian upheaval echoes what happened in Georgia, where protests over vote rigging led to the resignation of a Moscow-linked President and a landslide victory of a young, Western-educated and Western-oriented leader. For Moscow, the stakes are even higher in Ukraine. Unlike Georgia, Ukraine shares close ethnic and linguistic ties with Russia; Kiev, Ukraine"s capital, is the cradle of the Russian culture and the ancient capital of the first Russian state. President Vladimir V. Putin of Russia wants to forge a closer union between three Slavic nations Russia, Ukraine, and tiny, authoritarian Belarns and Ukraine is key to the plan, Russian businesses have major interests in Ukraine, which borders Russia to the west. The Russian military also wants to have Ukraine as an ally over which it can hold sway, not as a potential NATO participant, the analysts said. As other former republics turned away from Russia, Moscow "gets the feeling that Ukraine is its closest ally, with a symbolic significance," said Marsha Lipman of the Carnegie Moscow Center. "Russia has given itself a goal of getting a controllable Ukraine. I"m afraid it won"t happen." Putin quickly congratulated Yanukovych following Sunday"s vote, which pitted the prime minister against opposition leader Viktor Yushchenko. But Western observers reported voting fraud, and hundreds of thousands of Ukrainians rallied in protest. "If the crisis lasts, .it will become a potential source of problems for Russia"s relations with the West," said Alexander Pikayev, an independent politica! analyst in Moscow "Russia will have to share responsibility for the acute political crisis." The Kremlin had come out early and strongly for Yanukovych before the election. Putin traveled twice to Ukraine, ahead of each round of voting. To support the official purpose of his first visit, attending anniversary celebrations of Ukraine"s liberation from the Nazis in World War Ⅱ, the festivities were rescheduled for 10 days earlier than the actual date. Since the vote, the Kremlin"s propaganda machine has been in full swing. Russia"s Channel One television, controlled by the Kremlin like all other major networks accused the Ukrainian opposition of breaking the law by declaring Yushehenko the rightfully elected President. In his prime-time show, television commentator Mikhail Leontyev compared the Ukrainian opposition to Middle Eastern militants. "But this is not the Gaza Strip, and the chaos cannot go on indefinitely," he said, warning that protest strikes would only hurt ordinary people. Russian television also aired reports on the anniversary of Georgia"s "Rose Revolution" on Tuesday, saying the country was steeped in misery and poverty a year after the fall of the old government. Russian independent newspapers, however, which reach only a fraction of the TV audience, wrote about a different Georgia the same day telling how happy Georgians had decorated shop windows and restaurants with roses to celebrate. Many Russians view Ukraine"s powerful opposition as a kind of force that has disappeared in Russia under the increasingly authoritarian Putin administration. Russia has not had a seriously contested presidential election since 1996, when Boris Yeltsin narrowly defeated a Communist challenger. The political opposition here is fractured and marginalized, ousted from parliament in last year"s balloting closely directed by the Kremlin. Russian optimists hope a defeat of Yanukovyeh would force the Kremlin to reconsider its attempts to control political life in other former Soviet republics. Pessimists fear that his loss would only prompt the Kremlin to tighten its rule. "The stakes are high," Lipman said. "It"s a question of whether Russia"s neighbor will be a Ukraine ruled not through democratic institutes but through administrative means, or a Ukraine that will embrace democracy."

单选题I' ve been working on my vocabulary actively, and one way to ______ it is to see films in English on TV.

单选题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 Interactive television advertising, which allows viewers to use their remote controls to click on advertisements, has been pushed for years. Nearly a decade ago it was predicted that viewers of 'Friends', a popular situation comedy, would soon be able to purchase a sweater like Jennifer Aniston's with a few taps on their remote control. 'It's been the year of interactive television advertising for the last ten or twelve years,' says Colin Dixon of a digital-media consultancy. So the news that Cablevision, an American cable company, was rolling out interactive advertisements to all its customers on October 6th was greeted with some skepticism. During commercials, an overlay will appear at the bottom of the screen, prompting viewers to press a button to request a free sample or order a catalogue. Cablevision hopes to allow customers to buy things with their remote controls early next year. Television advertising could do with a boost. Spending fell by 10% in the first half of the year. The popularization of digital video recorders has caused advertisers to worry that their commercials will be skipped. Some are turning to the Internet, which is cheaper and offers concrete measurements like click-through rates—especially important at a time when marketing budgets are tight. With the launch of interactive advertising, 'many of the dollars that went to the Internet will come back to the TV,' says David Kline of Cablevision. Or so the industry hopes. In theory, interactive advertising can engage viewers in a way that 30-second spots do not. Unilever recently ran an interactive campaign for its Axe deodorant (除臭剂), which kept viewers engaged for more than three minutes on average. The amount spent on interactive advertising on television is still small. Magna, an advertising agency, reckons it will be worth about $138 million this year. That falls far short of the billions of dollars people once expected it to generate. But DirecTV, Comcast and Time Warner Cable have all invested in it. A new effort led by Canoe Ventures, a coalition of leading cable providers, aims to make interactive advertising available across America later this year. BrightLine iTV, which designs and sells interactive ads, says interest has surged: it expects its revenues almost to triple this year. BSkyB, Britain's biggest satellite-television service, already provides 9 million customers with interactive ads. Yet there are doubts whether people watching television, a 'lean back' medium, crave interaction. Click-through rates have been high so far (around 3-4%, compared with less than 0.3% online), but that may be a result of the novelty. Interactive ads and viewers might not go well together.
