  Secondary education in the USA

  Secondary Education in the USA, program of public education immediately following elementary schooling. It begins generally at the age of 12 to 14 and continues from four to six years. Some types of secondary education, such as vocational schooling, are terminal and prepare the student for employment upon graduation. Others lead to advanced training in colleges, universities, or technical schools. In the U.S., secondary education includes the junior and senior high schools. In many foreign countries, this level of education often embraces the junior or community college as well as the first two years of university training. The purpose of secondary education is to expand knowledge of subjects already studied, including the systematic study of literature, foreign languages, sciences, mathematics, social studies, and other subjects essential for physical and intellectual development and to prepare students as future citizens. In some countries, military training is also required.

                Cooperative Learning
  The idea remains that students are merely containers which a teacher fills with knowledge. However, this way of teaching no longer works. The teacher's role is no longer simply to feed information to students. Facts are available in books, on CD ROMS and on internet. What students need is the skills to find this information. Cooperative learning encourages responsibility, patience and helpfulness towards others. In cooperative learning classes, children do not sit in straight rows of desks facing the teacher, but rather face one another to make it easier to share ideas. They learn to work first in pairs, then in threes, and finally in teams of four. Students are required to participate actively in discussing and shaping their own knowledge. The teacher, who is still very important, becomes the helper rather than the master. But cooperative learning is not merely group work. Cooperative learning turns the classroom from a competitive arena into a place where learning facts and life skills are both fun and effective for students and teachers alike.

               College Life in the United States
  Teachers at American colleges and universities use many different teaching methods. Some teachers give assignments every day. They grade homework. Students in their classes have to take many quizzes, a midterm exam, and a final exam. Other teachers give only writing assignments. Some teachers always follow a course outline and usually use the textbook. Others send the students to the library for assignments.
  The atmosphere in some classrooms is very formal. Students call their teachers “Professor Smith”, “Mrs. Hones,” and so on. Some teachers wear business clothes and give lectures. Other classrooms have an informal atmosphere. Students and teacher discuss their ideas. Teachers dress informally, and students call them by their first names. American teachers are not alike in their teaching styles.
  At most American colleges and universities, facilities for learning and recreation are available to students. Students can often use type-writers, tape recorders, video machines, and computers at libraries and learning centers. They can buy books, notebooks, and other things at campus stores. They can get advice on their problems from counselors and individual help with their classes from tutors. Students can relax and have fun on campus, too. Some schools have swimming pools and tennis courts. Most have snack bars or cafeterias.

[基础知识]

1. 词法
  (1) once
    [说明] once作连词用表示“一旦,只要”,引导表示暗示一种条件的从句。
    例如:Once you understand the rules of the game, you will enjoy it.
    一旦你了解了游戏的规则,你就会喜欢它。
    Once he is free, he will play computer games.
    只要他有空,他就玩游戏。
  (2) unless
    [说明] unless 作连词用引导条件状语从句,表示“如果不,除非……”,
    相当于if…not的含义,但比if…not的语气要强。
    例如:You will not succeed unless you work hard.
    (= You will not succeed if you don't work hard.)
    如果你不努力奋斗,你不会成功。
    Unless you admit your mistake to him yourself,
    he will lose faith in you completely.
    除非你亲自向他承认错误,否则他会对你完全失去信心。
    当unless引导的从句的主语与主句的主语相同时,unless后面的主语和动词有时可省略。
    例如:Unless (he is ) in uniform, he doesn't look like a policeman.
    除非他穿着制服,他看起来不像警察。
    He will not come unless (he is) invited.
    除非被邀请,否则他是不会来的。
  (3) taste
    [说明]taste作及物动词表示“尝,品尝” “吃(饮食),吃出……”,后面直接+名词。
    作不及物动词表示“尝起来,感觉有……味道”。这时taste 的搭配形式是:
    taste + adj. / taste of + n. / taste like + n.
    例如:Taste the coffee and see if you like it.
    尝尝这咖啡,看你喜欢不喜欢。
    He has not tasted food for a whole day.
    他有一整天没吃东西了。
    You can taste nothing when you have a cold.

    这一结构表示“允许某人做某事”。
    它的被动形式是be allowed to do sth.“被允许做某事。”
    例如:My parents won't allow me to stay out late.
    我父母亲不允许我深夜呆在外边。
    Children are not allowed to enter the chemistry lab. 
    孩子们不允许进化学实验室。

    我不喜欢喝咖啡,给我茶好了。
    She invited Peter to the party, but his brother Bob came instead.
    她请彼得参加聚会,但来的却是他的哥哥鲍勃。
    instead of 是个介词词组,译为“代替……而不”。
    表示前者代替后者,并带有否定后者的含意。
    instead of后面可跟名词、代词、-ing形式或介词短语。
    例如:Many young people like pop songs instead of folk songs.
    许多年轻人喜欢流行歌曲,而不喜欢民间歌曲。
    I will go to see him instead of you.
    我要去看他而不是看你。
    They went swimming instead of staying at home.
    他们去游泳了而没呆在家里。
    We went to the Summer Palace by bike instead of by bus.
    我们没有乘公共汽车,而是骑自行车去的颐和园。
  (6) sure
    [说明]sure 是形容词,表示“确信的,肯定无疑的”。
    make sure表示“确定,查明,核实,弄清楚。”后跟that 从句或of sth.。
    例如:I only came to make sure that everything was all right.
    我只是来弄清楚是否一切都顺利。
    Make sure (that ) the windows are shut and the door is
    locked before you go to bed.
    睡觉前看一下是否关好窗户锁了门。
    We must make sure of the facts.
    我们必须把事实搞清楚。
  (7) rather
    [说明]rather 作副词用,译为“相当,有点儿”。它既可用来修饰形容词,也可用来修饰副词。
    例如:It is rather cold today.

    He spoke English rather well.
    他英语说得相当好。
    此外rather可用来修饰比较级。
    例如:He drives rather faster than he ought.

    当rather修饰名词,且名词前又有形容词来修饰时,我们可用 a + rather + adj. + n.或
    rather + a / an + adj. + n.两种结构。
    例如:It was a rather cold day. = It was rather a cold day.
    那是一个相当冷的日子。
