话题链接：近年来，随着网络的飞速发展，人们网上交流的日益频繁，网上交友也日渐增多，网上交友到底如何？请看下文，然后想一想。
Friendship in InternetIn so many ways, cyberspace(网络空间)mirrors the real world．People ask for information, play games, and share hobby tips there．Others buy and sell products．Still others look for friendship, or even love．
Unlike the real world, however, your knowledge about a person is limited to words on a computer screen．Identity and appearance mean very little in cyberspace．Rather, a person’s thoughts－or at least the thoughts they type－are what really count．So even the shyest person can become a chat-room star．Usually, this“faceless”communication doesn’t create problems．Identity doesn’t really matter when you’re in a chat room discussing politics or hobbies．
In fact, this emphasis on the ideas themselves makes the Internet a great place for exciting conversation．Where else can so many people come together to chat their interests?
But some Internet users want more than just someone to chat with．They are looking for serious love relationships．Is cyberspace a good place to find love?The answer depends on whom you ask．Some of these relationships actually succeed．Others fail miserably．
Supporters of online relationships say that the Internet allows people to get to know each other intellectually(理智)first．Personal appearance doesn’t get in the way．But critics of online relationships argue that no one can truly know another person in cyberspace．Why?Because the Internet gives users a lot of control over how others view them．Internet users can carefully play with their words to fit whatever image they want to give．And they don’t have to worry about what their“speechless”communication is doing for their image．In a sense, they are not really themselves．
All of this may be fine if the relationship stays in cyberspace．But not knowing about a person is a big problem in a love relationship．With so many unknowns its easy to let one’s imagination…
想一想：Discuss with your classmates about how to deal with the friends on the Internet?

话题链接：Proper habits of nutrition can be developed by paying attention to the variety of foods included in the diet; and the quantity of each kind of food eaten．A diet, or the food regularly eaten, must contain all the nutritional(营养的)elements．Different food contains different vitamins(维生素)，let's look at the food one by one．
EGGS
Eggs are an excellent source of complete protein(蛋白质)；they contain all essential amino acids(氨基酸)．One large egg contains 7 or 8 grams of first-class protein．Also found in eggs are vitamins A, B2, D, and E; niacin(烟酸)；copper; iron; phosphorus(磷)；and unsaturated(不饱和的)fats．The egg yolk contains the richest known source of choline, found in lecithin and necessary for keeping the cholesterol (胆固醇)within the egg emulsified(蛋白)．The egg yolk also contains biotin(维生素H)，one of the B-complex vitamins．
FIBER
Fiber is the part of food that is not digested by the human body, such as the skin of an apple and the husk(壳，皮)of a wheat kernel．The normal functioning of the intestinal tract depends upon the presence of adequate fiber．A low-fiber diet has been associated with heart disease, cancer of the colon and rectum(直肠)，diverticulosis(瘢痕形成)，varicose veins(纹理)，phlebitis(静脉炎)，and obesity．
FISH
Fish are excellent sources of high-grade protein, polyunsaturated fatty acids, and minerals, especially iodine(碘)and potassium(钾)．Fish are categorized as freshwater fish, saltwater fish, and shellfish．These types differ slightly in nutritive value．Freshwater fish provide magnesium(镁)，phosphorus, iron, and copper．Saltwater fish and shellfish are rich in iodine, fluorine(氟)，and cobalt (钴)．Fatty fish, such as halibut(比目鱼)，mackerel(鲭鱼)，and salmon, are good sources of vitamins A and D．Herring, oysters, and sardines contain vanadium and zinc．Shellfish are low fatty acids but are relatively high in cholesterol．
FRUITS
Fresh fruits are good sources of vitamins and minerals, especially vitamin A and C, carbohydrates in the form of cellulose and natural sugars, and water．They are good substitutes of such high-carbohydrate(碳水化合物)foods as candy, cookies, and cakes, which contain few nutrients．Yellow fruits, such as apricots, cantaloupe(香瓜)，and persimmons(柿子)，are good sources of carotene(胡萝卜素)，which is converted to vitamin A．Aside from acerola cherries and rose hips, the best natural sources of vitamin C are the citrus fruits, such as oranges, grapefruit, lemons, and tangerines(橘)；other sources of vitamin C are cantaloupe, strawberries, and tomatoes．Apples and bananas contain valuable bulk fiber in the form of indigestible(不可吸收的)cellulose, which is needed for regular bowel movement．Bananas are high in magnesium(镁)and may be useful for treatment of diarrhea, colitis, ulcers, and certain cases of protein allergies．Bananas and pears are the highest in natural sugars．
GRAINS
Grains are often referred to as cereals ;they are the seeds of various grasses such as wheat, oats, rice, and barley．Often called the “staff of life”, they provide the bulk of the world's food supply．Common foods made from these grains are flours, breads, breakfast cereals, and macaroni．

话题链接：中国中学生崇尚在发展自己兴趣爱好的同时，还要勤奋学习，为将来上一所好的大学努力拼搏。那么，对于远在大洋彼岸的美国中学生来说，他们的生活是否和我们相同呢？他们是否也和我们一样在为上一所好大学而“一心只读圣贤书”呢？
As a student,you must want to know something about American high school students．In fact, just like in China, in the United States, high school is usually divided into two parts, one is called “junior high school” and the other is “senior high school”．
In China, children enjoy free education of nine years, but in the United States, the students enjoy free education until they are eighteen years old．As a result of the free education system, American children have little difficulty in going to senior high school．
American high school students can take part in a lot of activities outside the classroom, such as joining a music group or a sports team．Certainly, just like students in China, American students have to work hard in order to get good marks if they want to go to a good university．They don’t specialize(专攻)in any special subjects, and they take classes in all kinds of subjects all through the high school time．And those who come out with low marks at the end of a school year and who are supposed to stay a grade are often allowed to go on to the next grade．
In American high schools, there is fighting or hurting or other kinds of bad behavior(行为)．So children who want to go to universities are often sent to suburban(郊外的)high schools, where most students aim at going to good universities and the atmosphere(气氛)is quite different．
Peter is a Grade One student in high school, and he has a part time job in a restaurant．He washes dishes on Saturdays and Sundays from 8∶00 a.m.until 4∶00 p.m．He can earn ＄5.50 an hour．He saves almost all the money he can get because he wants to go to a good university．The cost goes up every year in universities．Of course, He has to spend some money when he goes out on Saturday nights．
Jane is a student in high school．She is in Grade Two．She has a job as a cashier(收银员)in a shop．The job pays well－about ＄6.75 an hour．On weekdays, she works every night after school from 4∶00 until 8∶00．So she has no time for homework, and her grades aren’t very good this year．But she has to work, or she can’t buy nice clothes and can’t go out on Saturday nights．Also, her car costs a lot of money．
Lucy is a new student in a university．She finds a part time job and works in a law office for three hours every weekday afternoon．She does office work, like putting away papers and letters,for ＄8.25 an hour．The job gives her a good chance to learn things because she wants to be a lawyer someday．But she doesn’t want to work every term．She needs time to study．
美国的孩子自幼崇尚独立，成人以后，大都不愿依靠父母来养活自己了。凭着自己的劳动换来的收入，很多学生不但能自己支付上学的各种费用，而且还可以养车、娱乐、买时髦衣服呢！读读他们的日常生活安排，你有什么感触呢？
