(l)More and more of the world's supply of seafood is coming from farms. (2)Although 80% of the world's seafood comes from marine harvests, there is a major shift under way toward aquaculture now. (3)Nearly 40% of salmon marketed today are raised in captivity, compared with 6% a decade ago. Forty percent of all clams, oysters, and mussels are produced in farm environments, along with 65% of freshwater fish. Between 1990 and 1996, fish-farming production rose from 12.4 million to 23 million tons worldwide, writes Anne Platt McGinn in an article for World Watch magazine. (4) "The fact that world seafood supplies continue to increase at all is due almost entirely to the phenomenal growth in aquaculture," says McGinn, a research associate at the World Watch Institute. Commercial aquaculture is driven by rising human population at a time when over harvested wild fish stocks are in decline and conventional farm production has leveled off. (5)Biotechnology is contributing to high-yield aquaculture through transgenics—the transfer of genes from one species to another. Researchers introduce desirable genetic traits into fish, creating hardier stocks. For example, some species of fish have a protein that allows them to live in Arctic waters. By transplanting this "anti-freeze" gene into other species, researchers have created more fish that can survive in extremely cold water, according to Ag-West Biotech, Inc., in Saskatchewan, Canada. (6)Biotechnologists are attempting to improve a wide range of genetic traits in fish used for aquaculture, developing fish that are larger and faster-growing, more efficient in converting feed into muscle, more tolerant of low oxygen levels in water, and better able to resist disease. (7)Researchers also are seeking plant-based sources of food as a more efficient alternative to fishmeal. The use of plant protein on fish farms could take some of the pressure off wild fish stocks and address the problem of phosphorous pollution because plants do not contain high phosphorus levels. Wheat, canola, and canola oil are being used as alternative feed for aquaculture, according to Ag-West Biotech, Inc. (8)While aquaculture produces a reliable source of protein, the industry is rife with environmental problems, asserts McGinn. Perhaps the biggest concern is water pollution: Fish waste and uneaten food accumulates at farm sites and can float directly downstream into water supplies. Farm-related nutrient wastes as well as nitrogen and phosphorus also promote the spread of algal "blooms" that deplete oxygen and kill marine life. (9)Aquaculture is also an inefficient user of resources, McGinn charges. Fish farms need protein feed, and about 17% of ocean fish, an over harvested wild resource, becomes food for captive-bred fish. "An estimated five kilograms of oceanic fish reduced into fishmeal are required to raise one kilogram of farmed ocean fish or shrimp, representing a large net protein loss," says McGinn. (10)Fish farming does not have to be an inefficient or polluting industry. McGinn predicts that many consumers will choose sustainably produced fish in the future, just as they prefer dolphin-free tuna today.

Read carefully the following excerpt on paid vacation for only child employees, and then write your response in NO LESS THAN 200 words, in which you should: summarize the main message of the excerpt, and then comment on whether paid vacation for only child employees is necessary. You should support yourself with information from the excerpt. Marks will be awarded for content relevance, content sufficiency, organization and language quality. Failure to follow the above instructions may result in a loss of marks. Paid to Care for Aged Parents in Hospital The newly revised Henan Provincial Population and Family Planning Ordinances stipulate that an only child of a family can enjoy up to 20 days paid vacation every year to take care of their hospitalized parents above 60 years old, according to local reports. As China's society is aging, only children face great pressure to support their aged parents. The Law on Protection of Rights and Interests of Seniors stipulates that children should frequently visit their elderly parents, and the employers should guarantee employees' legal right to take vacations and visit their parents. An official of Henan Provincial Health and Family Planning Commission said the only child of a family is the only one who can look after his or her aged parents when they get sick, and the paid vacation aims to provide support to one-child families and help them cope in such a situation. The vacation is not only a positive attempt to deal with the aging society issue, but also a policy that promotes filial piety in society, and it has won wide public recognition. However, whether the policy can take effect depends on its implementation. The authorities should make more efforts to supervise enterprises and strengthen the social security mechanism.

Which of the following italicized phrases indicates purpose?
A. indicative B. reach C. immediate D. lack E. content-free F. tracking G. specifying H. at least I. clues J. same K. present L. strongly M. essence N. earliest O. style-free How does literary style evolve? Surprisingly,【C1】______ lie in words with seemingly little meaning, such as "to" and "that". By analysing how writers use such "【C2】______" words, Daniel Rockmore and colleagues at Dartmouth College in Hanover were able to conduct the first, large-scale style analysis of literature. Content-free words are【C3】______ of writing style, Rockmore says. While two authors might use the【C4】______ content words to describe a similar event, they will use content-free words to link their content words in a different way. Using the Project Gutenberg digital library, Rockmore's team analysed 7,733 English language works written since 1550,【C5】______ how often and in what context content-free words appeared. As you might expect, they found that writers were【C6】______ influenced by their predecessors. They also found that as the number of literature works grew, the influence of older works shrank. Authors in the【C7】______ periods wrote in a very similar way to one another, the researchers found, probably because they all read the same small body of literature. But approaching the modern era, when more people were writing and more works were available from many eras and numerous styles, authors' styles were still very similar to those of their【C8】______ contemporaries. "It's as if they find dialects in time," says Alex Bentley. "Content is what makes us unique, but content-free words put us in different groups." That writers should be most influenced by their contemporaries rather than the great works of the past is interesting, Rockmore says, because it challenges the【C9】______ of "classic" literature. When it comes to style【C10】______, perhaps we aren't so strongly influenced by the classics after all.
On further examination it was found that the signature was not______.
