Teamwork is just as important in science as it is on the playing field or in the gym Scientific investigations are almost always carded out by teams of people working together. Ideas are shared, experiences are designed, data are yzed, 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.

【单选题】The most obvious difference between the working class and the middle class in English is their(). A．dress B．work C．accent D．meal
A.
As regards social conventions, we must say a word about the well known English class system. This is an embarrassing subject for English people, and one they tend to be ashamed of, though during the present century class-consciousness has grown less and less, and the class system less rigid. But it still exists below the surface. Broadly speaking, it means there are two classes, the "middle class" and the "working class". (We shall ignore for a moment the old "upper class", including the hereditary aristocracy, since it is extremely small in numbers; but some of its members have the right to sit in the House of Lords, and some newspapers take a surprising interest in their private life.) The middle class consists chiefly of well to do businessmen and professional people of all kinds. The working class consists chiefly of manual and unskilled workers.
B.
The most obvious difference between them is in their accent. Middle class people use slightly varying kinds of "received pronunciation" which is the kind of English spoken by BBC announcers and taught to overseas pupils. Typical working class people speak in many different local accents which are generally felt to be rather ugly and uneducated. One of the biggest barriers of social equality in England is the two class education system. To have been to a so called "public school" immediately marks you out as one of the middle class. The middle classes tend to live a more formal life than working class people, and are usually more cultured. Their midday meal is "lunch" and they have a rather formal evening meal called "dinner", whereas the working man’s dinner, if his working hours permit, is at mid-day, and his smaller, late evening meal is called supper.
C.
As we have said, however, the class system is much less rigid than it was, and for a long time it has been government policy to reduce class distinctions. Working class students very commonly receive a university education and enter the professions, and working class incomes have grown so much recently that the distinctions between the two classes are becoming less and less clear. However, regardless of one’s social status, certain standards of politeness are expected of everybody, and a well bred person is polite to everyone he meets, and treats a laborer with the same respect he gives an important businessman. Servility inspires both embarrassment and dislike. Even the word "sir", except in school and in certain occupations (e.g. commerce, the army, etc.) sounds too servile to be commonly used.
