Because of the way light reflects off the organisms, these phytoplankton create colou
6、rful patterns at the ocean surface. Ocean colour varies from green to blue, depending on the type and concentration of phytoplankton. Climate change will fuel the growth of phytoplankton in some areas, while reducing it in other spots, leading to changes in the oceans appearance.Phytoplankton live a
7、t the ocean surface, where they pull carbon dioxide(二氧化碳)into the ocean while giving off oxygen. When these organisms die, they bury carbon in the deep ocean, an important process that helps to regulate the global climate. But phytoplankton are vulnerable to the oceans warming trend. Warming changes
8、 key characteristics of the ocean and can affect phytoplankton growth, since they need not onlysunlight and carbon dioxide to grow, but also nutrients.Stephanie Dutkiewicz, a scientist in MITs Center for Global Change Science, built a climate model that projects changes to the oceans throughout the
9、century. In a world that warms up by 3 , it found that multiple changes to the colour of the oceans would occur. The model projects that currently blue areas with little phytoplankton could become even bluer. But in some waters, such as those of the Arctic, a warming will make conditions riper for p

22、 course of American literature. His life was full of tragedies, but he had the great influence on the 19th-century American literature and continues to influence writers to this day.The early life of Edgar Allan Poe was quite unhappy. Born in 1809, Poe was not yet three years old when his parents di
23、ed. Adopted by a wealthy family, he got into trouble at school. He entered the United States Military Academy at West Point, but he dropped out without graduating. His misery (不幸 ) continued to his adult life. Later, because of a failed marriage, he suffered from mental illness. He was so upset abou
24、t real life that he turnedto writing. Expressing himself in an unreal and imaginary world was his only comfort.The tragedies in Poe s life influenced the tone, style and contents of his writing. His stories usually include death, which help build his reputation as a master of “ dark l” iterature. In
25、 his The Tell-Tale Heart, the main character goes crazy and kills his roommate while in The Black Cat, the main character kills his cat in a fit of madness.Poe died at the age of 40 in 1849.

30、our elderly and how to improve their lives. It is not only a financial problem but also a question of the system we want for our society. I would like to suggest several possible solutions to this problem.First, employers should take the responsibility for their retired employees. To make this possi
31、ble, a percentage of profits should be set aside for this purpose. But when a company must take life-long responsibility for its employees, it may suffer from a commercial disadvantage due to higher employee costs. Another way of solving theproblem is to return the responsibility to the individual.
32、This means each person must save during his working years to pay for his years of retirement. This does not seem a very fair model since some people have enough trouble paying for their daily life without trying to earn extra to cover their retirement years. This means the government might have to s
33、tep in to care for the poor.In addition, the government could take responsibility for the care of the elderly. This could be financed through government taxes to increase the level of pensions. Furthermore, some institutions should be created for senior citizens, which can help provide a comfortable
34、 life for them. Unfortunately, as the present situation in our country shows, this is not a truly viable answer. The government can seldom afford to care for the elderly, particularly when it is busy trying to care for the young.One further solution is that the government or social organizations est
35、ablish some working places especially for the elderly where they are independent.To sum up, all these options have advantages and disadvantages. Therefore, it is reasonable to expect that some combination of these options may be needed to provide the care we hope to give to our elderly generations.W
36、hat is the writer s main purpose in writing this article?To discuss some possible solutions to an important social problem.To make general readers aware of the problems of retired people.To point out the need for government support for old people.To instruct retired people on how they can have a hap
37、pier life.What does the underlined word“ viable ” in Paragraph 3 most probablymean?A. Impossible.B. Practical.C. Useful.D. Successful.According to the passage, how can the government help to improve the lives of retired people?Set aside some profits to help people with problems after they retire.Inc
38、rease savings levels of people during their working years.Increase the discounts for food and transport for the old.Make available pensions for those who have retired.What can be concluded from the passage?Taking care of the old is mainly an issue of money.Employers should allow their workers to ret
39、ire at a later age.There is no single solution to the problems of the old.Becoming independent should be the goal of most old people.參考答案Passage 1A 細節(jié)理解題。根據(jù)第二段最后一句Many of the plastic bottlesend up in landfills or are burned with other waste products可知, 廢棄塑料瓶的處理方法是被埋葬或焚燒。故選A。C 詞義猜測題。根據(jù)第三段中Those fiber
