Have you ever wondered what our future is like？ Practically all people【C1】______a desire to predict their future【C2】______People seem inclined to【C3】______this task u sing causal reasoning. First, we generally【C4】______that future circumstances are【C5】______caused or conditioned by present ones. We learn that getting an education will【C6】______how much money we earn later and that swimming beyond the reef may bring an unhappy【C7】______with a shark.
Second, people also learn that such【C8】______of cause and effect are probabilistic in nature. That is, the effects occur more often when the causes occur than when the causes are【C9】______, but not al ways.【C10】______, students learn that studying hard produces good grades【C11】______most instances, but not every time. Science makes these concepts of causality and probability more clear and【C12】______techniques for dealing with them more【C13】______than does causal human inquiry. In looking at ordinary human inquiry, we need to【C14】______between prediction and under .standing. Often, even if we don't under stand why, we are willing to act on the basis of a demonstrated【C15】______ability.
Whatever the primitive drives that【C16】______human beings, satisfying them depends heavily on the ability to predict future circumstances. The attempt to predict is often played in the【C17】______of knowledge and understanding. If you can understand why certain regular patterns【C18】______, you can predict better than if you simply ob serve those patterns. Thus, human inquiry aims【C19】______answering both "what" and "why" questions, and we【C20】______these goals by observing and figuring out.

A relationship with your customer is like any relationship: It【C1】______time to earn their trust and moments to【C2】______it. Customers want the truth, because without it they cannot make【C3】______decisions. For example, suppose you go out to dinner and the restaurant you choose has people waiting. When you put your name in, the host will tell you how long it is. If the host is doing his job, you will actually wait less than【C4】______you were told. If you are told the wait is 15 minutes and you are still waiting at the 30-minute mark, are you a happy customer？ At one level, it is just【C5】______. In some cases, it could【C6】______other plans: If you miss your movie because you were not【C7】______for dinner, you really are not a happy customer.
Unfortunately, many salespeople are【C8】______to tell the truth. They【C9】______some in formation, or share partial truths, or just plain lie. They do it in the【C10】______that customers will buy when they hear【C11】______they want to hear. It is true that customers want to hear certain things but【C12】______they are true. Let's go back to the restaurant.【C13】______the wait is not 15minutes-it is 90 minutes. It is not what we want to hear. Still, we can decide to stay or not to stay. If we do not stay, we will be hack. But if we【C14】______told 30 minutes and it became 90, that【C15】______the last time we ate there. Sooner or later, customers al ways find out the truth. If the truth is different than what they have been told, you have lost their trust.
Truth is【C16】______accuracy. It includes a willingness to stand behind what you say. In other words, are you willing to put your money【C17】______your mouth is？ If you are working with others, part of their【C18】______is that when something goes wrong you will stand with them. If an order is delayed, for example, how will you help them【C19】______their business commitments？ Part of earning their trust is having a backup plan in place should your【C20】______systems fail.
【C1】
A．takes
B．spends

In The Disuniting of America: Reflections on a Multicultural Society, Revised and Enlarged Edition (W. W. Norton) Schlesinger provides deep insights into the crises of nationhood in America. A new chapter assesses the impact both of radical multiculturalism and radical monoculturalism on the Bill of rights. Written with his usual clarity and force, the book brings a noted historian' s wisdom and perspective to bear on America' s "culture wars".
Schlesinger addresses the questions: What holds a nation together？ And what does it mean to be an American？ Describing the emerging cult of ethnicity, Schlesinger praises its healthy effect on a nation long shamed by a history of prejudice and narrow-mindedness. But he warns against the campaign of multicultural advocates to divide the nation into separate ethnic and racial communities. From the start, he observes, the United States has been a multicultural nation, rich in its diversity but held together by a shared commitment to the democratic process and by the freedom of intermarriage. It was this national talent for assimilation that impressed foreign visitors like Alexis de Tocqueyille and James Bryce, and it is this historic goal that Schlesinger champions as the best hope for the future. Schlesinger analyzes what he sees as grim consequences of identity politics: the widening of differences. Attacks on the First Amendment, he argues, threaten intellectual freedom and, ultimately, the future of the ethnic groups. His criticisms are not limited to the left. As a former target of McCarthyism, be understands that the radical right is even more willing than the radical left to re strict and weaken the Bill of Rights.
The author does not minimize the injustices concealed by the "melting pot" dream. The Disuniting of America is both academic and personal, forceful in argument, balanced in judgment. It is a book that will no doubt anger some readers, but it will surely make all of them think again. The winner of Pulitzer Prizes for history and for biography, an authoritative voice of American liberalism, Schlesinger is uniquely positioned to bring bold answers and healing wisdom to this passionate debate over who we are and what we should become.
According to Schlesinger, the United States is ______.
A．a melting pot
B．a nation with diverse cultures held together by the democratic process
C．a federation of ethnic and racial communities
D．a nation with various ethnic and racial groups

下列各 Most of us would shy away from making purchases in a foreign country ff we didnt know the exchange rate. Yet, ff privacy is the true currency of the Interuet, as many argue, millions of us are doing that very thing every day. i Meanwhile, Internet giants amend their privacy policies in ways that allow them to harvest and sell even more of our personal data. While privacy campaigners protest, users generally vote with their clicks and carry on regardless. So should we conclude the Interuet generation is happy to trade its privacy for free or cheaper Web services？ Not according to Nicola Jentzsch of the German Institute of Research in Berlin, and colleagues, who last week published research showing that most people prefer to protect their personal data when given a choice and that a significant proportion are willing to pay extra to do so. The researchers directed 443 students to a website offering tickets for a real movie showing, sold by two different uendors (商贩). Although the tickets were subsidized, the volunteers, who were able to purchase one, two, or no tickets, had to pay most of the cost themselves. When both vendors offered tickeks at the same price but only one required customers to enter their cell phone number, the more privacy-friendly yendor got 83% of sales. When participants were offered the santo choice, but with an additional charge of 50 euro cents from the privacy-friendly cinema, its market share fell to 31%. "It turns out that when you are good on privacy you can charge more and make a greater profit," says Alessandro Acquisti of the University of Cambridge, one of the authors of the study, published by the European Network and Information Security Agency. "What people say in surveys is that they care about privacy, but what they actually do is spend their time constantly updating their status on Facebo0k," says Acquisti. "This has led some to conclude that people no longer care about privacy. This new data, along with similar work we have done in the U. S, shows this is not the case, and that the desire for privacy is not dead after all. " According to the passage, many people believe that
A.we can benefit from selling our personal data
B.Internet giants should perfect their privacy policies
C.our privacy is the true currency of the Internet
D.privacy campaigners should vote with their clicks

To say that the child learns by imitation and that the way to teach is to set a good example is a bit oversimplified. No child imitates every action he sees. Sometimes, the example the parent wants him to follow is ignored while he takes over contrary patterns from some other ' example. Therefore we must turn to a more subtle theory than "Monkey see, monkey do".
Look at it from the child's point of view. Here he is in a new situation, lacking a ready response. He is seeking a response which will gain certain ends. If he lacks a ready response for the situation, and cannot reason out what to do, he observes a model who seems able to get the right result. The child looks for an authority or expert who can show what to do.
There is a second element at work in this situation. The child may be able to attain his immediate goal only to find that his method brings criticism from people who observe him. When shouting across the house achieves his immediate end of delivering a message, he is told emphatically that such a racket is unpleasant, that he should walk into the next room and say his say quietly. Thus, the desire to solve any objective situation is overlaid with the desire to solve it properly. One of the early things the child learns is that he gets more affection and approval when his parents like his response. Then other adults reward some actions and criticize others. If one is to maintain the support of others and his own self-respect, he must adopt responses his social group approves.
In finding trial responses, the learner does not choose models at random. He imitates the person who seems a good person to be like, rather than a person whose social status he wished to avoid. If the pupil wants to be a good violinist, he will observe and try to copy the techniques of capable players; while some other person may most influence his approach to books.
Admiration of one quality often leads us to admire a person as a whole, and he becomes an identifying figure. We use some people as models over a wide range of situations, imitating much that they do. We learn that they are dependable and rewarding models because imitating them leads to success.
The statement that children learn by imitation is incomplete because ______.
A．they only imitate authorities and experts
B．they are not willing to copy their parents
C．the process of identification has been ignored
D．the nature of their imitation as a form. of behavior. has been neglected
