(46) . Adding iron to patches of ocean can make plankton bloom temporarily. The microscopic organisms suck up dissolved carbon dioxide from the water, which in turn is replaced by carbon dioxide from the air. (47) . Jorge Sarmiento from Princeton and his colleagues developed a complex computer model to analyse how factors such as ocean chemistry and water circulation would affect the process if 160, 000 square kilometres of ocean were seeded with iron for a month. (48) . In their scenario, which covers an area 10 times as big as the largest experiment of this kind ever proposed, fertilising the ocean removes 1 million tonnes of carbon from the atmosphere -- just 0.2 per cent of the carbon dioxide humankind spews out each month. Rough estimates in the past have predicted similarly disappointing results. (49) says Sallie Chisholm, an environmental engineer from the Massachusetts Institute of Technology. "But the take-home message is the same. (50) "A Its opponents argue, however, that it will stop global warming.B Its opponents fear that it will damage the marine ecosystem, and now a computer model shows that the trick would also be remarkably inefficient.C As plankton die and settle on the ocean floor, their carbon is supposedly locked up in the seabed,D They found that 100 years later only between 2 and 11 per cent of the extra carbon that was originally taken up by plankton had actually been removed from the atmosphere.E "These are newer and better models,"F Ocean fertilisation is not the answer to global warming.

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。 Engineering Ethics Engineering ethics is attracting increasing interest in engineering universities throughout the nation. At Texas A&M University, evidence of this interest in professional ethics culminated in the creation of a new course in engineering ethics, as well as a project funded by the National Science Foundation to develop material for introducing ethical issues into required undergraduate engineering courses. A small group of faculty and administrators actively supported the growing effort at Texas A&M, yet this group must now expand to meet the needs of increasing numbers of students wishing to learn more about the value implications of their actions as professional engineers. The increasing concern for the value dimension of engineering is, at 1east in part, a result of the attention that the media has given to cases such as the Challenger disaster, the Kansas City Hyatt-Regency Hotel walkways collapse, and the Exxon oil spill. As a response to this concern, a new discipline, engineering ethics, is emerging. This discipline will doubtless take its place alongside such well-established fields as medical ethics, business ethics, and legal ethics. The problem presented by this development is that most engineering professors are not prepared to introduce literature in engineering ethics into their classrooms. They are most comfortable with quantitative concepts and often do not believe they are qualified to lead class discussions on ethics. Many engineering faculty members do not think that they have the time in an already overcrowded syllabus to introduce discussions on professional ethics, or the time in their own schedules to prepare the necessary material. Hopefully, the resources presented herein will be of assistance. It is likely that following this introductory passage, the author will provide the necessary material related to the topic of engineering ethics.
A. Right
B. Wrong
C. Not mentioned
下面有3篇短文,每篇短文后有5道题,每题后面有4个选项。请仔细阅读短文并根据短文回答其后面的问题,从4个选项中选择1个最佳答案。第一篇 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 journal 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 portein 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." According to the last paragraph, which of the following is NOT true
Adult chimps hunt monkeys while young chimps fish for termites.
B. The main source of animal protein for male chimps is colobus monkeys.
C. The main source of animal protein for female chimps is termites.
D. Female chimps fish for termites while watching their children.
