As part of more comprehensive compliance and ethics programs, many companies have formulated internal policies pertaining to the ethical conduct of employees.These policies can be simple exhortations in broad, highly-generalized language ( typically called a corporate ethics statement), or they can be more detailed policies, containing specific behavioral requirements (typically called corporate ethics codes).51They are generally meant to identify the company’s expectations of workers and to offer guidance on handling some of the more common ethical problems that might arise in the course of doing business.52 It is hoped that having such a policy will lead to greater ethical awareness , consistency in application, andthe avoidance of ethical disasters. 53. An increasing number of companies also requires employees to attend seminars regarding business conduct, which often include discussion of the company’s policies, specific case studies, and leEal requirements. Some companies even require their employees to sign agreements stating that they will abide by the company’s rules of conduct. Many companies are assessing the environmental factors that can lead employees to engage in unethical conduct.A competitive business environment may call for unethical behavior.Lying has become expected in fields such as trading.An example of this are the issues surrounding the unethical actions of the Saloman Brothers. Not everyone supports corporate policies that govern ethical conduct. Some claim that ethical problems are better dealt with by depending upon employees to use their own judgment. Others believe that corporate ethics policies are primarily rooted in utilitarian concerns, and that they are mainly to limit the company’s legal liability, or to curry public favor by giving the appearance of being a good corporate citizen.Ideally, the company will avoid a lawsuit because its employees will follow the rules.54 .Should a lawsuit occur, the company can claim that the problem would not have arisen if the employee had only followed the code properly. Sometimes there is disconnection between the company’s code of ethics and the company’s actual practices. 55. Thus, whether or not such conduct is explicitly sanctioned by management, at worst, this makes the policy duplicitous (搞两面派的) , and, at best, it is merely a marketing tool. An increasing number of companies also requires employees to attend seminars regarding business conduct, which often include discussion of the company’s policies, specific case studies, and leEal requirements.

Passage Three What exactly is a lie Is it anything we say which we know is untrue Or is it something more than that For example, suppose a friend wants to borrow some money from you, you say "I wish I could help you but I’m short of money myself." In fact, you are not short of money but your friend is in the habit of not paying his debts and you don’t want to hurt his feeling by reminding him of this.Is this really a lie Professor Jerald Jellison of the University of Southern California has made a scientific study of lying. According to him, women are better liars than men, particularly when telling a "white lie".For instance, when a woman at a party tells another woman that she likes her dress, she really thinks it looks awful. However, this is only one side of the story. Other researchers say that men are more likely to tell more serious lies, such as making a promise which they have no intention of fulfilling.This is the kind of lie politicians and businessmen are supposed to be particularly skilled at: the lie from which the liar hopes to profit or gain in some way. Research has also been done into the way people’s behavior changes in a number of small,apparently unimportant ways when they lie. It has been found that if they are sitting down at the time, they tend to move about in their chairs more than usual.To the trained observer they are saying "I wish I were somewhere else now" .They also tend to touch certain parts of the face more often, in particular the nose. One explanation of this may be that lying causes a slight increase in blood pressure.The tip of the nose is very sensitive to such changes and the increased pressure makes it itch. Another gesture which gives liars away is what the writer Desmond Morris in his book Man-watching calls "the mouth cover". He says there are several typical forms of this, such as covering part of the mouth with the fingers, touching the upper-lip or putting the hand at one side of the mouth.Such a gesture can be understood as an unconscious attempt on the part of the liar to stop himself or herself from lying. Of course, such gestures as rubbing the nose or covering the mouth or moving about in a chair cannot be taken as proof that the speaker is lying. They simply tend to occur more frequently in this situation.It is not one gesture alone that gives the liar away but a whole number of things, and in particular the context in which the lie is told. According to the passage, a "white lie" seems to be a lie ( ).
A. that other people believe
B. that other people don’t believe
C. told in order to avoid offending someone
D. told in order to take advantage of someone

Passage One We find that bright children are rarely held back by mixed-ability teaching. On the contrary, both their knowledge and experience are enriched.We feel that there are many disadvantages in streaming( 把…按能力分班)pupils.It does not take into account the fact that children develop at different rates. It can have a bad effect on both the bright and the not-so-bright child.After all, it can be quite discouraging to be at the bottom of the top grade! Besides, it is rather unreal to grade people just according to their intellectual ability.This is only one aspect of their total personality.We are concerned to develop the abilities of all our pupils to the full, not just their academic ability.We also value personal qualities and social skills and we find that mixed-ability teaching contributes to all these aspects of learning. In our classrooms, we work in various ways. The pupils often work in groups: this gives them the opportunity to learn to cooperate, to share, and to develop their leadership skills.They also learn how to cope with personal problems as well as learning how to think, to make decisions, to analyze and evaluate, and to communicate effectively.The pupils learn from each other as well as from the teacher. Sometimes the pupils work in pairs;sometimes they work on individual tasks and assignments, and they can do this at their own speed.They also have some formal class teaching when this is appropriate.We encourage our pupils to use the library, and we teach them the skills they need in order to do this efficiently.An advanced pupil can do advanced work;it does not matter what age the child is.We expect our pupils to do their best, not their least, and we give them every encouragement to attain this goal. Which of the following is not mentioned in the third paragraph
A. Group work gives pupils the opportunity to learn to work together with others.
B. Pupils also learn to develop their reasoning abilities.
C. Group work provides pupils with the opportunity to learn to be capable organizers.
D. Pupils also learn how to participate in teaching activities.
