　　Some people believe that greed and selfishness has become the basis of modern society, and we should return to the old traditions of family and community then we will have a better life．To what extent do you agree or disagree with the above opinion?

　　In this fast-paced world, many values are undergoing major changes．While people traditionally prioritize caring, sharing and generosity in life and work, modern people seem to be more self-absorbed and self-concerned．

　　Modern people act selfishly to survive the harsh competition of life．They say that it is a jungle out there．To survive, you have to fight with whatever means that come handy．Obviously greedy and selfishness go perfectly well with such ideas．In a company, employees do everything they can to get better pay and higher position, even at the cost of colleagues．We are in any way advocating any selfish conduct．It is just that people are pressured to act in a certain way due to outside influences．

　　In spite of common practice, it is hard to conclude that modern society is built on greed and selfishness, both of which are not newly invented vocabulary．In ancient times people also did greedy and selfish things though such behaviors were more condemned then．But we can not ignore the fact that people in the past lived a relatively more isolated life and faced less pressure compared with their modern counterparts．

　　Are we happier to share with others and be generous to them? There is no fixed answer either．Some people take great pleasure helping and giving to others while others feel happy doing the opposite．But I personally think that people should not be too selfish．Caring for others can actually encourage the development of a mutually beneficial relationship．

　　In conclusion, modern people appear to be more self-centered than those in the past due to strong outside pressure．However, we should encourage people to know the importance of being caring and generous and to build a mutually beneficial relationship with others．

　　Teamwork is just as important in science as it is on the playing field or in the gym．Scientific investigations(调查)are almost always carried out by teams of people working together．Ideas are shared, experiments are designed, data are analyzed, and results are evaluated and shared with other investigators．Group work is necessary, and is usually more productive than working alone．

　　Several times throughout the year you may be asked to work with one or more of your classmates．Whatever the task your group is assigned, a few rules need to be followed to ensure a productive and successful experience．

　　What comes first is to keep an open mind, because everyone’s ideas deserve consideration and each group member can make his or her own contribution．Secondly, it makes a job easier to divide the group task among all group members．Choose a role on the team that is best suited to your particular strengths．Thirdly, always work together, take turns, and encourage each other by listening, clarifying, and trusting one another．Mutual support and trust often make a great difference．

　　Activities like investigations are most effective when done by small groups．Here are some more suggestions for effective team performance during these activities：Make sure each group member understands and agrees to the task given to him or her, and everyone knows exactly when, why and what to do take turns doing various tasks during similar and repeated activities; be aware of where other group members are and what they are doing so as to ensure safety; be responsible for your own learning, though it is by no means unwise to compare your observations with those of other group members．

　　When there is research to be done, divide the topic into several areas, and this can explore the issue in a very detailed way．You are encouraged to keep records of the sources used by each person, which helps you trace back to the origin of the problems that may happen unexpectedly．A format for exchanging information(e．g．, photocopies of notes, oral discussion, etc．)is also important, for a well-chosen method not only strengthens what you present but also makes yourself easily understood．When the time comes to make a decision and take a position on an issue, allow for the contributions of each member of the group．Most important of all, it is always wise to make decisions by compromise and agreement．

　　After you’ve completed a task with your team, make an evaluation of the team’s effectiveness－the strengths and weaknesses, opportunities and challenges．
