单选题Which of the following is NOT true about Phyllis in the early 1770s?

单选题Cooperation is the common endeavor of two or more people to perform a task or reach a jointly cherished goal. Like competition and conflict, there are different forms of cooperation, based on group organization and attitudes. In the first form, known as primary cooperation, group and individual unite. The group contains nearly all of each individual's life. The rewards of the group's work are shared with each member. There is an interlocking identity of individual, group, and task performed. Means and goals become one, for cooperation itself is valued. While primary cooperation is most often characteristic of preliterate societies, secondary cooperation is characteristic of many modern societies. In secondary cooperation, individuals devote only part of their lives to the group. Cooperation itself is not a value. Most members of the group feel loyalty, but the welfare of the group is not the first consideration. Members perform tasks so that they can separately enjoy the fruits of their cooperation in the form of salary, prestige, or power. Business offices and professional athletic teams are examples of secondary cooperation. In the third type, called tertiary cooperation or accommodation, latent conflict underlies the shared work. The attitudes of the cooperating parties are purely opportunistic; the organization is loose and fragile. Accommodation involves common means to achieve antagonistic goals; it breaks down when the common means cease to aid each party in reaching its goals. This is not, strictly speaking, cooperation at all, and hence the somewhat contradictory term antagonistic cooperation is sometimes used for this relationship.

单选题As with any work of art, the merit of Chapman Kelley"s "Wildflower Works I" was in the eye of the beholder . Kelley, who normally works with paint and canvas, considered the twin oval gardens planted in 1984 at Daley Bicentennial Park his most important piece. The Chicago Park District considered it a patch of raggedy vegetation on public property that could be dug up and replanted at will like the flower boxes along Michigan Avenue. And that"s what happened in June 2004, when the district decided to create a more orderly vista for pedestrians crossing from Millennium Park via the new Frank Gehry footbridge. If you"re looking for evidence that the rubes who run the Park District don"t know art when they see it, all you have to do is visit what"s left of Kelley"s masterpiece. The exuberant 1.5-acre tangle of leggy wildflowers is now confined to a tidy rectangle, restrained on all sides by a knee-high hedge and surrounded by a closely cropped lawn. White hydrangeas and pink shrub roses complete the look. We don"t know who"s responsible for the redesign, but we"ll bet the carpet in his home doesn"t go with the furniture. Still, you"d think the Park District was within its rights to plow under the prairie. Wrong. Kelley just won at lawsuit in which he argued that the garden was public are and therefore protected by the federal Visual Artists Rights Act . Under that law, the district should have given him 90 days" notice that it intended to mess with his artwork instead of rushing headlong into the demolition, a la Meigs Field. That way Kelley could have mounted a legal challenge, or at least removed the plants. Park District officials said they never considered the garden a work of art, even though it was installed by an established artist and not, say, Joe"s Sod and Landscaping. We can understand their confusion. Just recently, we figured out that the caged greenery directly south of Pritzker Pavilion is supposed to be an architectural statement and not a Christmas tree lot. All that"s left is for the district to compensate Kelley for his loss. Whatever price the parties settle on, let"s hope the agreement also provides for the removal of the rest of "Wildflower Works I." If it was"t an eyesore before—and plenty of people thought it was...it sure is now.

单选题Is test anxiety destructive.? Can we make test anxiety work for us? The answer to both of these questions is yes. Test anxiety often interferes with student performance but this same test anxiety, if channeled correctly, can help improve performance. In order to lessen the destructive elements of test anxiety, the approach should be to develop improved confidence and knowledge. As your knowledge of the course material increases, your confidence in your ability to succeed will increase. As your confidence increases, your anxiety will go down, allowing your knowledge to come through more efficiently. The way you prepare for a test can reduce anxiety during the test. You will be surprised how confident you will feel if you know the material. Studies of memory show if you want to be able to recall information from text or lecture you have to review that material several times. It is important to know your own abilities and operate accordingly. If you know that you learn best by listening, prepare a tape of significant material and listen to the tape. Study partners or study groups are often useful for self-testing. Experience in stressful situations tends to lessen anxiety in those situations. One way to help yourself retrieve material is through the use of mnemonic codes. Learn a code that lets you remember complex material. Developing an outline for an essay question that you know will be on the test or memorizing a formula are forms of code development. Students are often frustrated by the sheer volume of material that has to be studied in college. Many instructors conduct reviews, give hints, identify what is important to study, use handouts or overhead transparency outlines. These materials should be at the top of your study list. If the instructor took the time to identify them, you should assume that they will play an important part of the test. While knowledge acquired during test preparation can help reduce anxiety, it is another thing to take the test itself. Following are a few suggestions to help reduce anxiety during the test. When I arrive at a test, I often find students flipping text pages at the last minute trying to cram it all in at the end. You would be better off trying to relax, meditating a little, and clearing your mind to allow yourself the ability to concentrate on the questions that are coming. As soon as the instructor gives you the signal to start, dump out formulas, codes, outlines from your memory onto the test answer sheets so that you will not have to worry about whether you will remember the codes long enough until you get to the appropriate test question. You can build your confidence if you go through the test and answer all of the questions that you know first. Go back and work on those questions that need greater analysis, or that need to be worked out or need to be guessed at and your anxiety will not kick in until later in the test. For those of you whose anxiety increases as study and preparation increase, your goal should be to start concentrating on things that take your mind off the test, i. e. , television, books, hobbies, movies, etc. Meditation and aerobic exercise have proven to be very useful methods for reducing undesirable effects of stress. The solution to reducing the destructive influences of stress is to plan to study. Map out a schedule of when you will study each day. Identify the specific topics that you will study each day. Identify the areas of the material that you have had problems with and study those. Your plan should include reading the text material, reviewing notes and homework assignments, identifying material that needs further explanation, developing codes for memory material and testing yourself. Once you have studied adequately, your confidence will be fairly high, your knowledge will be satisfactory to do well on the test and the stomach butterflies will help you focus on the task at hand. I'd wish you good luck on finals, but you and I both know that the more effectively you study, the luckier you will get.

单选题{{B}}Passage One{{/B}} The Federal Government联邦政府 The ConstitutionWhen America broke away from Britain in 1775, she did not adopt a British Constitution. The British have always had an unwritten constitution, whereas every item of the American Constitution is clearly written down and numbered, and can only be changed by a two-thirds majority vote of Congress. Yet in their different ways, the American and British forms of government did have one thing in common. They were both democratiC．As for American society, it was more democratic than British society, in that it paid less attention to class or wealth. Political Parties There are two major political parties in the USA, the Democratic Party and the Republican Party. The policies of the two parties are not basically opposed to one another. Inside both parties there moderates and right-wringers, though the Democrats still have the reputation of being somewhat more liberal than the Republicans. Voters are influenced by family traditions, but there are plenty of ordinary people who vote according to their hopes, fears and beliefs. There are no other political parties that can compete with the two big parties, though there are occasionally independents who stand for the presidency and manage to collect quite a few votes. There are no left-wing parties. Most Americans are in favor of free enterprise, believing that it may one day help them fulfill the American Dream. The President and Congress The President of the USA has more power than any other president in the democratic world- except the French President. It is he who formulates foreign policy and prepares laws for the home front. He is leader of the nation and Commander-in-Chief of the Armed Forces. He represents the USA and, since the USA is a super power, the eyes of the whole world are on him. The fate of the world is in his hands, or so many people believe, and one careless, ill-prepared speech by him could precipitate a crises. Actually, a great deal of the President's power is controlled by Congress, the American name for "parliament". It is Congress that declares war, not the President. Unlike the Prime Minister of Great Britain, or of Germany, he can make a treaty with a foreign power. But this treaty must be debated and agreed by Congress before it comes into force. The same control applies to laws at home. Congress has (on several occasions) refused to ratify treaties or given approval to laws proposed by the President. The USA is the only country, apart from France, where a president can rule with a parliament, the majority of whose members do not belong to his own political party. Some Americans have the feeling that idealism has gone out of politics and that personal ambition and money have taken its place. The election campaign fro the Presidency is unique in the amount of money poured into it. The wooing of voters lasts for months. But before the campaign for the election of the President can begin, each political party has to choose its candidate for the Presidency. This can lead to some very close contests. Men aspiring to be elected as the party candidate employ top public relations and advertising men, who invent clever catch phrases and set about "selling" their man. There are whistle stop tours by train, by plane, by car. The candidate delivers countless speeches and shakes countless hands. This razzamatazz typifies American enthusiasm and extravagance. Big money is necessary to support a presidential candidate's campaign and the candidate himself must be rich enough to pay his share. An attractive wife is an advantage, too. Money is also needed to become the Governor of a state, or a successful Senator, or member of the House of Representatives. Yet from this small group many excellent men have become President, and the same is true of members of Congress. It is very unlikely that the President could ever become a dictator. Congress, the press and the people between them rule out such a possibility. The Supreme Court Perhaps the most effective safeguard of democracy is the Supreme Court, for one of its objects is to protect the individual against the government. It has the authority to cancel a law which it considers violates the Constitution. The Court sits for at least four days a week and any individual who has a grievance against the government can apply to it for help. The Supreme Court goes way back to 1787, the days of the Founding Fathers, and is one of the cornerstones of American democracy. It gives judgement in disputes between States, or between a State and the Federal Government, and without invitation can declare a law made by Congress to be unconstitutional. The great Jefferson, who drew up the Declaration of Independence, saw to it, too, that there was a Bill of Rights which every American could thrust under the nose of anyone who tries to rob him of his freedom as a democratic citizen.
