Oceanography has been defined as "The application of all sciences to the study of the sea"． Before the nineteenth century， scientists with an interest in the sea were few and far between． Certainly Newton considered some theoretical aspects of it in his writings， but he was unwilling to go to sea to further his work． For most people the sea was remote， and with the exception of early intercontinental travelers or others who earned a living from the sea， there was little reason to ask many questions about it， let alone to ask what lay beneath the surface． The first time that the question "What is at the bottom of the oceans？" had to be answered with any commercial consequence was when the laying of a telegraph cable（电缆）from Europe to America was proposed． The engineers had to know the depth profile（起伏形状）of the route to estimate the length of cable that had to be made． It was to Maury of the US Navy that the Atlantic Telegraph Company turned， in 1853， for information on this matter． In the 1840s， Maury had been responsible for encouraging voyages during which soundings（测深）were taken to investigate the depths of the North Atlantic and Pacific Oceans． Later， some of his findings aroused much popular interest in his book ---The Physical Geography of the Sea．The cable was laid， but not until 1866 was the connection made permanent and reliable． At the early attempts， the cable failed and when it was taken out for repairs it was found to be covered in living growths， a fact which defied contemporary scientific opinion that there was no life in the deeper parts of the sea．Within a few years oceanography was under way． In 1872 Thomson led a scientific expedition， which lasted for four years and brought home thousands of samples from the sea． Their classification and analysis occupied scientists for years and led to a five-volume report， the last volume being published in 1895．（1）The passage implies that the telegraph cable was built mainly ____ ．A．for oceanographic studiesB．for military purposesC．for business considerationsD．for investigating the depths of the oceans（2）The aim of voyages Maury encouraged in the 1840s was ____ ．A．to make some sound experiments in the oceansB．to collect samples of sea plants and animalsC．to estimate the length of cable that was to be madeD．to measure the depths of the two oceans（3）The underlined word "defied" in the 4th paragraph probably means ____ ．A．doubtedB．challengedC．gave proof toD．agreed to（4）The theme of this passage is about ____ ．A．the beginnings of oceanographyB．the laying of the first undersea cableC．the investigation of ocean depthsD．the early intercontinental communications

The phrase "progressive education" is one, if not of protest, at least of contrast, of contrast with an education which was predominantly static in subject-matter, authoritarian in methods, and mainly passive and receptive from the side of the young. But the philosophy of education must go beyond any idea of education that is formed by way of contrast, reaction and protest. For it is an attempt to discover what education is and how it takes place. Only when we identify education with schooling does it seem to be a simple thing to tell what education actually is, and yet a clear idea of what it is gives us our only criterion for judging and directing what goes on in schools. It is sometimes supposed that it is the business of the philosophy of education to tell what education should be. But the only way of deciding what education should be, at least, the only way which does not lead us into the clouds, is discovery of what actually takes place when education really occurs. And before we can formulate a philosophy of education we must know how human nature is constituted in the concrete; we must know about the working of actual social forces; we must know about the operations through which basic raw materials are modified into something of greater value. The need for a philosophy of education is thus fundamentally the need for finding out what education really is. We have to take those cases in which we find there is a real development of desirable powers, and then find out how this development took place. Then we can project what has taken place in these instances as a guide for directing our other efforts. The need for this discovery and this projection is the need for a philosophy of education. What then is education when we find actual satisfactory specimens of it in existence In the first place, it is a process of development, of growth. And it is the process and not merely the result that is important. A truly healthy person is not something fixed and completed. He is a person whose processes and activities go on in such a way that he will continue to be healthy. Similarly, an educated person is the person who has the power to go on and get more education. In any case, development, growth, involve change, modification, and modification in definite directions. It is quite possible for a teacher, under the supposed sanction of the idea of cultivating individuality, to fixate a pupil more or less at his existing level. Respect for individuality is primarily intellectual. It signifies studying the individual to see what is there to work with. Having this sympathetic understanding, the practical work then begins, for the practical work is one of modification, of changing, of reconstruction continued without end. The change must at least be towards more effective techniques, towards greater self-reliance, towards a more thoughtful and inquiring disposition, one more capable of persistent effort in meeting obstacles. The philosophy of education is supposed A. to result from real understanding of actual schooling.B. to lead to overall prescription of practical education.C. to have happened when education came into existence.D. to be the basis on which practical education is formulated.
First two hours, now three hours—this is how far in advance authorities are recommending people show up to catch a domestic flight, at least at some major U.S. airports with increasingly massive security lines.Americans are willing to tolerate time-consuming security protocols in return for increased safety. The crash of EgyptAir Flight 804, which terrorists may have downed over the Mediterranean Sea, provides another tragic reminder of why. But demanding too much of air travelers or providing too little security in return undermines public support for the process. And it should: Wasted time is a drag on Americans' economic and private lives, not to mention infuriating.Last year, the Transportation Security Administration (TSA) found in a secret check that undercover investigators were able to sneak weapons—both fake and real—past airport security nearly every time they tried. Enhanced security measures since then, combined with a rise in airline travel due to the improving economy and low oil prices, have resulted in long waits at major airports such as Chicago's O'Hare International. It is not yet clear how much more effective airline security has become—but the lines are obvious.Part of the issue is that the government did not anticipate the steep increase in airline travel, so the TSA is now rushing to get new screeners on the line. Part of the issue is that airports have only so much room for screening lanes. Another factor may be that more people are trying to overpack their carry-on bags to avoid checked-baggage fees, though the airlines strongly dispute this.There is one step the TSA could take that would not require remodeling airports or rushing to hire: Enroll more people in the PreCheck program. PreCheck is supposed to be a win-win for travelers and the TSA. Passengers who pass a background check are eligible to use expedited screening lanes. This allows the TSA to focus on travelers who are higher risk, saving time for everyone involved. TSA wants to enroll 25 million people in PreCheck.It has not gotten anywhere close to that, and one big reason is sticker shock: Passengers must pay ＄85 every five years to process their background checks. Since the beginning, this price tag has been PreCheck's fatal flaw. Upcoming reforms might bring the price to a more reasonable level. But Congress should look into doing so directly, by helping to finance PreCheck enrollment or to cut costs in other ways.The TSA cannot continue diverting resources into underused PreCheck lanes while most of the traveling public suffers in unnecessary lines. It is long past time to make the program work. (1)The crash of EgyptAir Flight 804 is mentioned to . A.explain American's tolerance of current security checks B.stress the urgency to strengthen security worldwide C.highlight the necessity of upgrading major D.emphasize the importance of privacy protection (2)Which of the following contributes to long waits at major airports?

The Harry Potter series, written by J.K. Rowling, is perhaps the most popular set of novels of the modern era. With seven books and many successful films to its name, the series has gathered about 15 billion dollars in sales. How did the series become so popular? The reason can be broken down into several areas.The first book in the series was rejected 12 times before it was picked up by Bloomsbury—a small publisher in England. So receiving this contract was Rowling's first step to success. However, getting a book contract does not ensure the success of a book. The story was soon loved by children and adults alike. In light of this, Bloomsbury Publishing published a second version of the books with “adult” (less colorful and more boring) book covers. This made it easier for a full range of ages to enjoy the series.Another factor that worked like a charm was that the publisher and Rowling herself, through the books, conducted midnight releases, promotions, and pre-ordering more readers. Customers who feared that their local bookstore would run out of copies responded by pre-ordering over 700,000 copies before the July 8, 2000 release.What does the underlined word “releases” (Para. 3) mean?A. The activity that frees or expresses energy or emotion.B. The announcement about the book’s publishing information.C. The sales of books that is available only at midnight.

The increase in international business and in foreign investment has created a need for executives with knowledge of foreign languages and skills in cross-cultural communication. Americans, however, have not been well trained in either area and, consequently, have not enjoyed the same level of success in negotiation in an international arena as have their foreign counterparts. Negotiating is the process of communicating back and forth for the purpose of reaching an agreement. It involves persuasion and compromise, but in order to participate in either one, the negotiators must understand the ways in which people are persuaded and how compromise is reached within the culture of the negotiation. In many international business negotiations abroad, Americans are perceived as wealthy and impersonal. It often appears to the foreign negotiator that the American represents a large multi-million-dollar corporation that can afford to pay the price without bargaining further. The American negotiator’s role becomes that of an impersonal supplier of information and cash. In studies of American negotiators abroad, several traits have been identified that may serve to confirm this stereotypical perception, while undermining the negotiator’s position. Two traits in particular that cause cross-cultural misunderstanding are directness and impatience on the part of the American negotiator. Furthermore, American negotiators often insist on realizing short-term goals. Foreign negotiators, on the other hand, may value the relationship established between negotiators and may be willing to invest time in it for long-term benefits. In order to solidify the relationship, they may opt for indirect interactions without regard for the time involved in getting to know the other negotiator. Clearly, perceptions and differences in values affect the outcomes of negotiations and the success of negotiators. For Americans to play a more effective role in international business negotiations, they must put forth more effort to improve cross-cultural understanding. [共5题](1)What kind of manager is needed in present international business and foreign investment? [本题2分]A. The man who represents a large multi-million-dollar corporation. B. The man with knowledge of foreign languages and skills in cross-cultural communication. C. The man who is wealthy and impersonal. D. The man who can negotiate with his foreign counterparts.

Nothing healthful should be omitted from the meal because of a (56) dislike. At meal times it is a good idea to give a child a small portion and let him (57) back for a second helping rather than give him as much as he is likely to eat all at once. Do not talk too much to the child (58) meal times, but let him get on with his food, and do not allow him to leave the table immediately after a meal or he will soon learn to swallow his food (59) he can hurry back to his toys.

Americans experience more food recalls (召回) today than they did five years ago, especially when it comes to meat and poultry (家禽). Meat and poultry recalls increased by two-thirds from 2013 to 2018, while food recalls overall went up 10%, according to the report recently published by the U.S. Public Interest Research Group.Meanwhile, the U.S. Centers for Disease Control and Prevention estimates (估计) 48 million people get sick, 128,000 are hospitalized and 3,000 die from food-borne disease each year in the U.S. "We are looking for the farm-to-fork preventative solutions," said Adam Garber, the research group's consumer watchdog. "By doing that, we can protect people's health."Over the five-year period, poultry posted the most recalls (168), followed by beef (137) and pork (128). The report shows the most serious meat recalls are on the rise. Among meat and poultry, the number of Class I recalls has increased by 83%, nearly doubling. Class I, the most serious of the recalls, is issued when there is a reasonable probability that the food will cause health problems or death.53. When would Class I recalls be issued?A. When the food is likely to cause health problems or death.B. When there are too many complaints from customers.C. When the food problem lasts for five years.D. When the product quality is below standard.
