问答题中国的饮食文化 俗话说“民以食为天”。饮食文化，即围绕着人们日常工作中的食物、饮料及其食用方法所形成的文化现象，亦称饮食习俗。 从新石器时代的半坡村文化遗址中发现，早在五六千年前，中国北方的黄河流域已普遍种植粟这种农作物。同样，在距今7,000年前的河姆渡文化遗址中，也发现了南方人种植水稻的痕迹。这两个发现证明：6,000年前，南方人食大米，北方人吃小米的饮食习俗已经形成。南北方的食品风格不同。以大米为主食的南方食品较为简单，而以面粉为主食的北方食品则较为复杂。明代，又从南美传入了甜薯、土豆和玉米等农作物。 筷子是人们日常生活中最常用的一种进餐工具，已有数千年的历史。一位西方人曾说过：中国的筷子充分利用了杠杆原理，必须通过全身130多块骨头和肌肉的协调动作，才能使用筷子。筷子的发明充分显示了中国人的灵巧和智慧。

问答题春节 中国的春节在农历一月一日，是新一年的开始。这是举家团圆的时刻。一般说来，在春节前几天，只要有可能的话，多数人无论身处何地都会回家。就像圣诞节一样，人们会买很多东西如食品、礼物、衣服和烟花爆竹给孩子们。在除夕之夜，多数农村家庭仍然保持着一些传统习俗，如在两扇门上都贴上门神和春联。他们把“福”字倒贴在墙上和家具的门上，意思是“福到了”。除夕之夜的年夜饭是必不可少的程序。全家人围坐着一张桌子一同分享佳肴，人多的话兴许不止一张桌子。家人还会为没能赶回家的亲人留些座位，仿佛他们也在一起吃似的。年夜饭过后，大家会坐在一起，观看中央电视台的春节特别节目，等待，新年的到来。午夜将近时，特别节目也接近尾声，这时家家户户都到户外去放鞭炮。据说这样可以驱妖除魔。新年的早饭是很特别的，北方人吃饺子，南方人吃糯米饭团。走亲访友从新年的第一天就开始了，俗称“拜年”。每到这时，孩子们是最开心的，因为他们可以从长辈那里拿到压岁钱，据说压岁钱能带给他们好运。新年第五天，人们祭拜财神，送走新年。春节就结束了。
问答题Classes at American College The year at an American college is divided into 2 semesters or 3 quarters. Semesters are 15 weeks; quarters are 10 weeks. American college students usually attend school from September to May. Occasionally their academic pursuits extend into the summer. Students choose their classes a few weeks prior to the start of each term. Universities offer a great many classes in the students’ main area of study and in other areas as well. Students must take both. These include science, mathematics, computer, history and English. Other classes may be just for fun, like dance, theater or sports. Tests usually are given in the middle of the term and at the end3. The final examinations are extremely important. In some classes, the professor asks the students to write a research paper or complete a certain task instead of taking a test. Classes usually are organized through lectures. For example, a student may attend 2 or 3 lectures a week by the professor. As many as several hundred students sit at each lecture. Sometimes they also attend a smaller class to ask questions and discuss what the professor says4. These small classes are taught by professor’s assistants. In science classes, students also have a long laboratory class each week. What do American students study at college? The US Department of Education says the most popular area of study is sciences and management. Next is social science, which encompasses history, sociology, literature, public relations and political science. English is another popular field of study. Then comes computer science and health and life sciences like biology, chemistry and physics. Education is popular, too. Foreign languages are not popular as a main area of study among American college students. However, students at many colleges must study a language other than English before they can graduate. The most popular foreign language is Spanish, followed by French and German.
