阅读理解      Even plants can run a fever, especially when they"re under attack by insects or disease. But unlike
human, plants can have their temperature taken from 3,000 feet away-straight up. A decade ago,
adopting the infrared(红外线)scanning technology developed for military purposes and other satellites,
physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which
ones are under stress. The goal was to let farmers precisely target pesticide(***虫剂)spraying rather than
rain poison on a whole field, which invariably includes plants that don"t have pest problems.
     Even better, Paley"s Remote Scanning Services Company could detect crop problems before they
became visible to the eye. Mounted on a plane flown at 3,000 feet at night, an infrared scanner measured
the heat emitted by crops. The data were transformed into a colourcoded map showing where plants
were running "fevers". Farmers could then spotspray, using 50 to 70 percent less pesticide than they
otherwise would.
      The bad news is that Paley"s company closed down in 1984, after only three years. Farmers resisted
the new technology and longterm backers were hard to find. But with the renewed concern about
pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation.
Agriculture experts have no doubt the technology works. "This technique can be used on 75 percent of
agricultural land in the United States, " says George Oerther of Texas A & M. Ray Jackson, who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade.  But only if Paley finds the financial backing which he failed to obtain 10 years ago.

1. Plants will send out an increased amount of heat when they are________.
A. facing an infrared scanner
B. sprayed with pesticides
C. in poor physical condition
D. exposed to excessive sun rays

2. In order to apply pesticide spraying precisely, we can use infrared scanning to________.
A. estimate the damage to the crops
B. draw a colourcoded map
C. measure the size of the affected area
D. locate the problem area

3. Farmers can save a considerable amount of pesticide by________.
A. resorting to spotspraying
B. transforming poisoned rain
C. consulting infrared scanning experts
D. detecting crop problems at an early stage

阅读理解     Nuclearpowered aircraft carriers are considered one of the most important marine weapons in the
20th century. So far, only two countries in the world, the USA and France, have ever produced them.
But these fearful fighting machines are about to enter Asia.
     The US Navy said last month that one of its nine nuclearpowered aircraft carriers will be sent to
Japan to replace the diesel(柴油)powered carrier Kitty Hawk in 2008. In an agreement on October
30, the two countries also planned to level up their military (军事的) cooperation and the USA called
for Japan to take a larger role in alliance military moves.
     It will be the first time that a nuclearpowered carrier is based in Japan. Bombed by US forces in
World War ? at Hiroshima and Nagasaki, Japan is the only world country to have been attacked by a
nuclear weapon. Therefore, the citizens are highly sensitive to where nuclearpowered weapons are
based.
      "A radiation leak at Yokosuka would kill 100,000 people as far away as Tokyo, and could cause
billions of dollars in damage," said Masahiko Goto, leader of a protest group in Yokosuka. His group
has collected more than 300,000 signatures of people across Japan opposed to the nuclear carrier.
     The 44yearold Kitty Hawk, the US Navy"s oldest active ship, has been based in Yokosuka since
1998. It had returned to the US to be decommissioned in 2008. The new carrier, yet to be unveiled,_
will travel faster, be capable of supporting longer operations and carry with it the Navy"s most modern
technology.
     Experts pointed that this change is not only to strengthen the USJapan military alliance but also to
keep the military power of China and North Korea within limits. However, even Japanese experts don"t
believe that the two countries are threats to the region.
     "There is no need for Japan to have a nuclear carrier as defense," said Tetsuo Maeda, an international
relations professor at Tokyo International University. He said that the change of ship indicates an
increased military capability in the region, much more than what is needed.

1. With such a formidable weapon to enter its country, Japanese citizens ________.
A. are aware of its benefits to the country
B. are anxious about its potential danger
C. are curious about the advanced technology
D. are against where the carrier will be based

2. The replacement of the aircraft carrier is intended to________.
A. set up a kind of base in Japan
B. strengthen the USJapan military alliance
C. show Japan"s greater military capability
D. get rid of the dated marine weapon

3. From the story, we learn that________.
A. no other countries except the USA and France possess aircraft carriers
B. Japan has long planned to increase its military capability with new weapons
C. Japan will be the first country in Asia to have a nuclear aircraft carrier
D. Japan will be the third country to produce a nuclearpowered aircraft carrier

4. The underlined word "unveiled" in the fifth paragraph probably means________.
A. perfected
B. discussed about
C. produced
D. brought to view

They may be small and not able to speak, but babies are proving their amazing cleverness. Scientists began finding infants" skills are more than they are supposed to be. _________ Speaking of music, babies can"t seem to resist it. Not only are their ears turned to the beats, babies can actually dance to the music. To test babies" dancing ability, the researchers played recordings of classical music, rhythmic beats and speech to infants, and recorded the results. They also invited professional dancers to analyze how well the babies matched their movements to the music. The babies moved their arms, hands, legs feet and heads in response to the music, much more than to the speech. The finding suggests this dancing ability is innate(与生俱来的) in humans, though the researchers aren"t sure why it becomes weaker later in their life. Learning Quickly while Sleeping Babies can learn even while asleep, according to a 2011 study. In experiments with 26 sleeping infants, each just 1 to 2 days old, scientists played a musical tone followed by a puff of air to their eyes 200 times over the course of a half-hour. 124 electrodes(电极) stuck on the head and face of each baby recorded brain activity during the experiments. The babies rapidly learned to foretell a puff of air upon hearing the tone, showing a four-time increase on average in the chances of tightening their eyelids in response to the sound by the end of the experiments. As newborns spend most of their time asleep, this newfound ability might be crucial to rapidly adapting to the world around them and help to ensure their survival, researchers said. Judging Characters Well Judging another person helpful or harmful is crucial when choosing friends. And that ability starts early. Kiley Hamlin of Yale University showed both 6-and 10-month-olds a puppet(木偶) show, in which one character helped another climb a hill. In another scene a third character pushed the climber down. The little ones then got to choose which character they preferred. For both age groups, most babies chose the helper character. This character-judging ability could be baby"s first step in the formation of morals, Hamlin thought.

Mobile phones are an important business tool for farmers in rural areas. But they also put a valuable educational tool in their hands. The University of Illinois in the United States has a project called SAWBO-Scientific Animations Without Borders. It produces educational videos that can be downloaded to cell phones. The goal is to help people in developing countries improve their lives. One video shows farmers how to make a natural insecticide from neem seeds to prevent insect damage to crops. The process starts with sorting and drying the neem fruits. Then let the fruit dry in the sun for about three or four days, until they become brown. Using a mortar(碾槌) and stick, the fruits are slightly pounded to remove the shells from the fruits without breaking the seed inside. The videos use computer animation(动画). Some of the animated characters are a little funny looking-like a farmer with a long nose. But the subjects are serious, including a health video on preventing cholera(霍乱). Team member Francisco Seufferheld says the information in the videos is meant to be quickly understood. He says, "The information is digested in such a way that in two minutes, we can transmit a complex idea." The researchers tested the seven-minute video on seven mobile phones. They wanted to see if people would share the video using Bluetooth wireless technology. With Bluetooth, files can be passed to a nearby phone even if neither phone is connected to the Internet. As a result, in one month, the video had spread to one hundred eighteen people in fifty different villages. "This is just incredible impact," said Francisco Seufferheld. The team has made a few videos so far. These are available in a total of eighty languages, dialects and accents. Professor Barry Pittendrigh says there are plans for more videos later this year.

We might like to think we"re not influenced by other people, but a new study into the group-buying mechanisms(机制) - like those used on coupon(优惠券) sites such as Groupon and LivingSocial-reveals that telling buyers who come later to the offer how many have already signed up increases the number of purchasers. Researchers at the University of Toronto"s Rotman School of Management wanted to understand why group buying sites that have entered the market recently have enjoyed greater success than those operating a decade ago, such as Mercata and MobShop. Earlier attempts typically left potential buyers waiting for days before confirming whether or not they had got the offer they had signed up for. "We think one of the reasons group-buying has been successful recently is because of the short tim e horizon," says Rotman Professor Ming Hu, who co-wrote the study with Professor Mengze Shi and PhD student Jiahua Wu. "It allows for a herding effect." Another reason is the use of an information structure that discloses to later arrivals how many have already signed onto the deal. Researchers looked at two ways of designing the purchasing mechanism for a group buy: a simultaneous mechanism, where no one knows how many buyers have come before them, and a sequential(连续的) mechanism, where a second group of buyers has the advantage of knowing the size of the first group. The researchers" analytical(分析的) model shows the most successful mechanism is the sequential one because it eliminates uncertainty for those coming later to the deal, and improves the confidence of those who sign on early, as they"re able to track the numbers of those who come after them. "That boosts confidence," says Professor Hu, who teaches operations management. Deals for "luxury" services, versus everyday items, work better in a group buy scenario(方案) because they offer consumers a greater benefit.
1. It can be learned from the text that ______.
A. the short time horizon is the reason why group-buying has been successful. B. a simultaneous mechanism is where a group of buyers has the advantage of knowing how many people have signed up. C. a sequential mechanism allows a herding effect which boosts the confidence of the buyers. D. researchers at the University of Toronto"s Rotman School of Management carried out an experiment about why group buying sites entered the market successfully, such as Mercata and MobShop.
2. The underlined word "eliminates" in paragraph 7 probably means"______".
A. to become or to make something greater in amount, number, value B. to remove or get rid of something C. to deliberately not include something in what you are doing or considering D. to make something known to somebody
3. What can be the best title for the passage?
A. Secret for marketing success - boosting confidence. B. Secret for group-buying mechanism-herding effect. C. Comparison between a simultaneous mechanism and a sequential mechanism. D. What others do influences our decisions.
