    A group of happy, high-performing individuals is not a team. Even if each of the people is highly motivated and wants to do great work, you will still need to spend time actively developing a sense of unity and cooperation to create a truly team-oriented(团队精神的)environment. 【小题1】
    Building a team takes time. 【小题2】 We will review the building blocks of a team environment, so you can work on this aspect of your role over time.
    Successful teams have some common attributes（品质） you can encourage and develop as you work with the members of your group.【小题3】Making them clear to every member of your group is a great first step toward developing a team-oriented culture.
    All effective teams operate on the basis of trust. 【小题4】Each member on your team needs to see consistent(一致的)behavior patterns from you and their colleagues over time to be able to believe a certain person will act in a certain way.
    【小题5】  While having these discussions can be great for your team’s creativity, you want to ensure they remain within respectful communication. Challenging another team member’s view can help refine an idea and make it more perfect. You should encourage everyone to contribute to the discussion.
    A．Building a great team needs a lot of skills.
    B．A healthy team will have debates, and sometimes even heated discussions.
    C．Your aim is to encourage your team members to work together.
    D．You can’t expect to achieve success quickly.
    E. You will need to show these values through your actions as well as your words.
    F. Therefore, working with others is not the same as being mutually（相互地） supportive and dependent on one another.
    G. Trust is based on pattern recognition.

    第二节 （共5小题；每小题2分，满分10分）
    根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
    Why do some people have many friends while others do not? ___71___ However, it is not so. Let’s look at two psychological experiments which will give you the key to happy interpersonal relations.
    The first experiment is called the “Hawthorne effect” after Hawthorne, Illinois(伊利诺斯[美国州名]), where the experiment took place. A group of psychologists examined the work patterns of two groups of workers in the Western Electric Company. ____72_____. The psychologists changed the working conditions for one group twice but left the other group alone. They were surprised to find that productivity increased on both occasions and in both groups. They concluded that the increase in productivity came from the attention given to the workers by the management. It had increased their motivation and so they had worked harder. In other words, if you take an interest in others, they will want to please you and you will have good relations with them.
    ___73___. After Martin Luther King, Jr was killed in 1960s, a teacher, Jane Elliott, living in an all- white town decided to help her class of young children understand why the Civil Rights Movement had been necessary in America.
    She divided the class into two groups: one with blue eyes and other with brown eyes. Other eye colors such as hazel or green were excluded from his exercise. Then she told the class that brown-eyed people were cleverer than blue-eyed ones because of an agent(化学作用) for brown color found in their blood. Blue-eyed people were stupid, lazy and not to be trusted. Jane Elliott did not need to say any more. The brown-eyed students quickly got used to their new role as the leaders of the class. The blue-eyed students became quiet and withdrawn. Then she discovered something very interesting. Four poor brown-eyed readers began to read fluently in a way they had never done before. ___74___. So if you want to be successful and happy, take an interest in others whether they are your classmates or workmates. Congratulate them on their success and sympathize with them in their troubles. ___75___.
    A．Before the experiment the management talked to both groups of workers and explained that they wanted to find the best working environment for them.
    B．Remember that the way you treat others will decide their attitude and behavior to you.
    C．The second experiment shows what happens to personal relations if you are rude to or ignore others.
    D．The ones who have more friends usually are those who care about others.
    E. Jane Elliott had shown that the way people are treated affects not only their behavior but also their confidence and their performance.
    F. You may even imagine that this ability was something they were born with because it seems so effortless to them.
    G. The second experiment tells us what teachers said had a great effect on the students.
