Psychologists take opposing views of how external rewards, from warm praise to old cash, affect motivation and creativity. Behaviorists, who study the relation between actions and, argue that rewards can improve performance at work and school. Some other researchers who study various aspects of mental life, maintain those rewards often destroy creativity byencouraging dependence on approval and gifts from others. The latter view has gained many supporters, especially among educators. But the careful use of small monetary rewards sparks in grade-school children suggesting that properly presented inducements indeed aid inventiveness, according to a study in the June Journal Personality and Social Psychology. “If they know they're working for a reward and can focus on a relatively challenging task, they show the most creativity,”says Robert Esenberger of the University of Delaware in Newark. “But it's easy to kill creativity by giving rewards for poor performance or creating too much anticipation for rewards.” A teacher who continually draws attention to rewards or who hands out high grades for ordinary achievement ends up with uninspired students, Esenberger holds. As an example of the latter point, he notes growing efforts at major universities to tighten grading standards and restore falling grades. In earlier grades, the use of so-called token economics, in which students handle challenging problems and receive performance-based points toward valued rewards, shows promise in raising effort and creativity, the Delaware psychologist claims. 1. Psychologists are divided with regard to their attitudes toward ____. A) the choice between spiritual encouragement and monetary rewards B) the appropriate amount of external rewards C) the study of relationship between actions and D) the effects of external rewards on students' performance 2. What is the view held by many educators concerning external rewards for students? A) They approve of external rewards. B) They don't think external rewards. C) They have doubts about external rewards. D) They believe external rewards can motivate small children, but not college students. 3. According to the result of the study mentioned in the passage, what should educators do to stimulate motivation and creativity? A) Give rewards for performances which deserve them. B) Always promise rewards. C) Assign tasks which are not very challenging. D) Be more lenient to students when mistakes are made. 4. It can be inferred from the passage that major universities are trying to tighten their grading standards because they believe ____. A) rewarding poor performance may kill the creativity of students’ B) punishment is more effective than rewarding C) failing uninspired students helps improve their overall academic standards D) discouraging the students anticipation for easy rewards is matter of urgency 5．Which of the following facts about “token economics”is not correct? A) Students are assigned challenging tasks.
Question 1 M: After high school, I’d like to go to college and major in business administration. W: But I’d rather spend my college days finding out how children learn. Q: What do we learn from the conversation? Question 2 W: Is everything ready for the conference? M: The only thing left to do is set up the microphones and speakers. They'll be here in a few minutes. Q: What preparations have yet to be made? Question 3 W: Is it almost time to go home now? I'm so tired. I can hardly see straight. M: Just a few more minutes, then we can go. Q: What is the woman’s problem? Question 4 W: I'm not sure what I’m in a mood for. Ice-cream or sandwiches? They are both really good here. M: The movie starts in an hour. And we still have to get there and park. So just make a decision. Q: What does the man mean? Question 5 W: Tom said he would come to repair our solar heater when he has time. M: He often says he is willing to help, but he never seems to have time. Q: What does the man imply about Tom? Question 6 W: So you know that Sam turns down the job offered by the travel agency.

2013年12月英语四级真题答案及解析（完整版） 作文部分： 范文一： The modern technology has greatly altered the mode of communication among people. With the help of the Internet, people can easily contact each other anytime anywhere. However, the side effect is that many people have become over-dependent on the Internet and neglected face-to-face communication. As far as I'm concerned, electronic communication cannot fully replace the direct contact among people. Although it seems to bring everyone together, it actually estranges people and decreases the effectiveness of communication. A typical example is that, traditionally, people working in the same office simply walk to others and talk. Today, however, co-workers tend to send e-mails or instant messages through the Internet even when they are sitting next to each other. As words can never convey the full message, it usually takes much more time and rounds of conversation than face-to-face communication, in which people can discuss more directly with less loss of information. To conclude, the Internet enables more effective communication in some situations, but over-dependence on it actually pulls people apart. 范文二： It is frequently observed that many people keep looking down at their mobile phones whatever they are doing. It is true that mobile phones have brought great convenience to us as we can send short messages, check e-mails, surf the Internet, or watch videos almost anywhere. However, the overuse of mobile phones also leads to some serious problems. The over-dependence on mobile phones can harm the relationship among friends and family. With mobile phones, people do not talk as much as before. For example, sometimes at dinner tables, instead of chatting and laughing with each other, many people choose to chat with other friends online. In other words, mobile phones help people contacting friends far away more easily at the expense of reducing the communication with those who are sitting right next to them.
