One of the most vivid symbols of global warming is the torrents of melt water that drain from the lakes that form each summer on Greenland’s ice sheet. Recent studies have shown that this water, which flows deep into the ice through natural drainpipes called moulins, allows the ice to slide faster over bedrock toward the ocean. And the faster the ice flows, the faster sea levels rise. But a Dutch study using 17 years of satellite measurements in western Greenland suggests that the movement associated with the meltwater is not as rapid as had been feared. The acceleration appears to be a transient summer phenomenon, the researchers said, with the yearly movement actually dropping slightly in some places. "The positive-feedback ,mechanism between melt rate and ice velocity," says the report, published Friday in the journal Science, "appears to be a seasonal process that may have only a limited effect on the response of the ice sheet to climate warming over the next decades." Greenland is still losing more ice through melting than it gains through snowfall, other measurements show. The study was led by Roderik S. W. van de Wal of the Institute for Marine and Atmospheric Research of the University of Utrecht. He said the overall slowdown might be because of changing plumbing deep inside the ice. The study builds on earlier work also showing a limited overall change in ice flow from the surface melting. The authors and independent experts familiar with the research stressed that the findings did not preclude the possibility that more widespread surface melting could eventually destabilize big areas of Greenland, the world’s second largest ice storehouse. Richard B. Alley, a glaciologist at Pennsylvania State University, said that big lakes were likely to form as areas of melting spread inland, and that this could unlock new ice regions to start sliding more. But Dr. Alley and other experts said the new study showed that it was unlikely that Greenland’s ice had already become destabilized in ways that could cause a surge in sea levels. Which of the following is probably NOT a direct result of global warming according to the passage

What we know of prenatal development makes all this attempt made by a mother to mold the character of her unborn child by studying poetry, art, or mathematics during pregnancy seem utterly impossible. How could such extremely complex influences pass from the mother to the child There is no connection between their nervous systems. Even the blood vessels of mother and child do not join directly. An emotional shock to the mother will affect her child, because it changes the activity of her glands and so the chemistry of her blood. Any chemical change in the mother’s blood will affect the child for better or worse. But we can not see how a looking for mathematics or poetic genius can be dissolved in blood and produce a similar liking or genius in the child. In our discussion of instincts we saw that there was reason to believe that whatever we inherit must be of some very simple sort rather than any complicated or very definite kind of behavior. It is certain that no one inherits a knowledge of mathematics. It may be, however, that children inherit more or less of a rather general ability that we may call intelligence. If very intelligent children become deeply interested in mathematics, they will probably make a success of that study. As for musical ability, it may be that what is inherited is an especially sensitive ear, a peculiar structure of the hands or the vocal organs connections between nerves and muscles that make it comparatively easy to learn the movements a musician must execute, and particularly vigorous emotions. If these factors are all organized around music, the child may become a musician. The same factors, in other circumstance might be organized about some other center of interest. The rich emotional equipment might find expression in poetry. The capable fingers might develop skill in surgery. It is not the knowledge of music that is inherited, then nor even the love of it, but a certain bodily structure that makes it comparatively easy to acquire musical knowledge and skill. Whether that ability shall be directed toward music or some other undertaking may be decided entirely by forces in the environment in which a child grows up. Which of the following is the most important to make a child become a musician
案例： 某省重点工程项目计划于2004年12月28日开工，由于工程复杂，技术难度高，一般施工队伍难以胜任，业主自行决定采取邀请招标的方式，并于2004年9月8日向通过资格预审的 A、B、C、D、E五家施工承包企业发出了投标邀请书。该五家企业均接受了邀请，并于规定时间9月20～22日购买了招标文件。招标文件中规定，10月18日下午4时是招标文件规定的摊贩标截止时间，11月10日发出中标通知书。 在投标截止时间之前，A、B、D、E四家企业提交了投标文件，但C企业于10月18日下午 5时才送达，原因是中途堵车。10月21日下午由当地招投标监督管理办公室主持进行了公开开标。 评标委员会成员共有7人组成，其中当地招投标监督管理办公室1人、公证处1人、招标人1人、技术经济方面专家4人。评标时发现E企业投标文件虽无法定代表人签字和委托人授权书，但投标文件均已有项目经理签字并加盖了单位公章。评标委员会于10月28日提出了书面评标报行。B、A企业分列综合得分第一、第二名。由于B企业投标报价高于A企业， 11月10日招标人向A企业发出了中标通知书，并于12月12日签订了书面合同。 请指出评标委员会成员组成的不妥之处，并说明理由。
Do you ask yourself any of these questions What is abstract art Is it the same thing as Modern Art How can I interpret and evaluate a piece of abstract art Can it have a subject or a meaning Are there different types of abstract art If you want to discover the answers, and ask more questions, this course is for you! Abstraction is not a style of art, like for example, Baroque or Cubism. It is, rather, about the subject matter and our reading of it. An artist expressing the beauty of a landscape can paint a picture of the landscape, but how can an artist make a piece of artwork about an emotion such as fear, or an idea such as purity, or a quality of a painting such as shape, weight or rhythm It might be worth considering your expectations of some other art forms, music and dance for example. The art critic Herbert Read wrote in 1931, "We must not be afraid of this word ’abstract’. All art is primarily abstract". But many people are afraid of abstract art, and feel that it is alien territory! In this course we will approach abstract art via art with which we, perhaps, feel more comfortable and learn to extend our skills of interpretation and understanding. We will also make sure that terms bandied around in art speak such as "abstract", "figurative", "realism", "representational" are clearly defined. We will explore what we mean by realism and abstraction in Western art by looking at images from the ancient Egyptians, through Classical art, early Christian and Mediaeval art, to the Renaissance, until the late 19th century. We will then explore the break with convention in Modernism, look at experiments with colour and form in the early Modern era, and at some of the key ideas of the first abstract artists. We will examine the historical, social and political context of early Modernism, against the backdrop of rapid industrialization, the Bolshevik revolution and the years leading to the great war. Abstract Art flourished in the 1950s, after the Second World War, with the way being led by American Abstract Expressionism. Why the sudden outpouring of huge abstract paintings Could anyone do the "splash and drip" technique And why did so many abstract painters, including Marc Rothko and Jackson Pollock, meet untimely violent deaths Finally, we will ask. why does abstract art appear to be relatively unfashionable in our Post Modernist times, and has it got a future or shall we relegate it to the art history books The word "relegate" in the last paragraph is synonymous ______.
