单选题Lifetime Employment in Japanese Companies In most large Japanese companies, there is a policy of lifetime employment. What this means is that when people leave school or university to join an enterprise, they can expect to remain with that organization until they retire. In effect, the employee gets job security for life, and can only be fired for serious mistakes in work. Even in times of business recession, he or she is free from the fear of being laid off. One result of this practice is that the Japanese worker identifies closely with his company and feels strong loyalty to it. By working hard for the company, he believes he is safeguarding his own future. It is not surprising that devotion to one"s company is considered a great virtue in Japan. A man is often prepared to put his firm"s interests before those of his immediate family. The job security guaranteed by this system influences the way employees approach their work. They tend to think in terms of what they can achieve throughout their career. This is because they are not judged on how they are performing during a short period of time. They can afford to take a longer perspective than their western counterparts. This marriage between the employee and the company—the consequence of lifetime employment—may explain why Japanese workers seem positively to love the products their company is producing and why they are willing to stay on after work, for little overtime pay, to participate in earnest discussions about the quality control of their products.

单选题Young Female Chimps Outlearn Their Brothers Young female chimps are faster and better learners than young male chimps, suggests a new study, echoing learning differences seen in human girls and boys. While young male chimps pass their time playing, young female chimps carefully study their mothers. As a result, they learn how to fish for tasty termite snacks over two years before the boys. Elizabeth Lonsdorf, now at Lincoln Park Zoo in Chicago, US, and colleagues at the University of Minnesota, Saint Paul, spent four years watching how young chimpanzees in the Gombe National Park in Tanzania learned "cultural behavior". The sex differences in learning behavior were "consistent and strikingly apparent", says the team. The researchers point out that similar differences are seen in human children with regard to skills such as writing. "A sex-based learning differences may therefore date back at least to the last common ancestor of chimpanzees and humans," they write in the Nature. Chimps make flexible tools from vegetation and then insert them into termite mounds, extract them and then munch the termites clinging onto the tool. The researchers used video cameras to record this feeding behavior and found that each chimp mother had her own technique, such as how she used tools of different lengths. Analysis of the six infants whose ages were known showed that girl chimps were an average of 31 months old when they succeeded in fishing out their termites, where the boy chimps were aged 58 months on average. Females were also more skillful at getting out more termites with every dip and used techniques similar to their mothers while males did not. Instead of studying their mothers, the boy chimps spent a significantly greater amount of time frolicking around the termite mound. Behaviors such as playing or swinging might help the male infants later in life when typically male activities like hunting or fighting for dominance become important, suggest the researchers. Lonsdorf adds that there are just two main sources of animal protein for chimps--the termites or colobus monkeys. "Mature males often hunt monkeys up trees, but females are almost always either pregnant or burdened with a clinging infant. This makes hunting difficult," she says. "Adult females spend more time fishing for termites than males." So becoming proficient at termite fishing could mean adult females eat better. "They can watch their offspring at the same time. The young of both sexes seem to pursue activities related to their adult sex roles at a Very young age. /

单选题Facebook Changes Privacy Policy Facebook has agreed to make worldwide changes to its privacy policy as a result of negotiations with Canada's privacy commissioner. Last month the social network was found to breach Canadian law by holding on to users' personal data indefinitely. Facebook has now agreed to make changes to the way it handles this information and be more transparent about what data it collects and why. It will also make it clear that users carl deactivate or delete their account. As well as updating the privacy policy, Facebook has said it will make changes that will give users more control over the data they provide to third-party developers of applications, such as games and quizzes. There are around 950,000 developers in 180 countries that provide applications for the site. Specifically, the changes will require applications to state which information they wish to access and obtain consent from the user before it is used or shared. "Application developers have had virtually unrestricted access to Facebook users' personal information," said Ms Stoddart. "The changes Facebook plans to introduce will allow users to control the types of personal information that applications can access." The site will also encourage users to review their privacy settings and make it clear to users that they can delete or deactivate an account, and what the difference is between the two. Facebook's Michael Richter said if a user chose to deactivate their account, the site would still store theft information "even if it is for 10 years". "We're committing to that user." he said. "We want them to know that if they change their mind they can always come back." The social network has said work on the changes will begin immediately but they would take around 12 months to implement. The regulator first started its investigation as a result of complaints by the Canadian Interact Policy and Public Interest Clinic (CIPPIC) at the University of Ottawa. The country is the first to complete a full investigation of Facebook's privacy practices. Canada has around 12 million Facebook users, more than one in three of the population.

单选题下面的短文有15处空白，请根据短文内容为每处空白确定1个最佳选项。 Wonder Webs Spider webs are more than homes, and they are ingenious traps. And the world's best web spinner may be the Goldern Orb Weaver spider. The female Orb Weaver spins a web of fibers thin enough to be invisible to insect, yet {{U}}(51) {{/U}} enough to snare a flying bird without breaking. The secret of the web's strength. A type of super-resilient {{U}}(52) {{/U}} called dragline. When the female spider is ready to {{U}}(53) {{/U}} the web's spokes and frame, she uses her legs to draw the airy thread out through a hollow nozzle in her belly. Dragline is not sticky, so the spider can race back and forth along {{U}}(54) {{/U}} to spin the web's trademark spiral. Unlike some spiders that weave a new web every day, a Golden Orb Weaver {{U}}(55) {{/U}} her handiwork until it fails apart, sometimes not for two years. The silky thread is five times stronger than steel by weight and absorbs the force of an impact three times better than Kevlar, a high strength human-made {{U}}(56) {{/U}} used in bullet-proof vests. And thanks to its high tensile strength, or the ability to resist breaking under the pulling force called tension, a single strand can stretch up to 40 percent longer than its original {{U}}(57) {{/U}} and snap back as well as new. No human-made fiber even comes {{U}}(58) {{/U}}. It is no {{U}}(59) {{/U}} manufacturers are clamoring for spider silk. In the consumer pipeline: high-performance fabrics for athletes and stockings that never run. Think parachute cords and suspension bridge cables. A steady {{U}}(60) {{/U}} of spider silk would be worth billions of dollars— but how to produce it? Harvesting silk on spider farms does not {{U}}(61) {{/U}} because the territorial arthropods have a tendency to devour their neighbors. Now, scientists at the biotechnology company Nexia are spinning artificial silk modeled after Goldern Orb dragline. The {{U}}(62) {{/U}} step: extract silk-making genes from the spiders. Next, implant the genes into goat egg cells. The nanny goats that grow from the eggs secrete dragline silk proteins in their {{U}}(63) {{/U}}. "The young goats pass on the silk-making gene without {{U}}(64) {{/U}} help from us," says Nexia president Jeffrey Turner. Nexia is still perfecting the spinning process, but they hope artificial spider silk will soon be snagging customers {{U}}(65) {{/U}} the real thing snags bugs.

Therefore, if you want to gain weight, you must do {{U}} {{U}} 12 {{/U}} {{/U}}of two things: eat more calories (units of heat, therefore energy), or use less through {{U}} {{U}} 13 {{/U}} {{/U}}. If you want to lose weight, you do the {{U}} {{U}} 14 {{/U}} {{/U}}, decrease your intake of calories or increase the amount of energy you spend. There is {{U}} {{U}} 15 {{/U}} {{/U}}way. Gaining or losing weight is always a relation between intake and output of potential energy.
