話題鏈接：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(營養的)elements．Different food contains different vitamins(維生素)，let's look at the food one by one．
EGGS
Eggs are an excellent source of complete protein(蛋白質)；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(煙酸)；copper; iron; phosphorus(磷)；and unsaturated(不飽和的)fats．The egg yolk contains the richest known source of choline, found in lecithin and necessary for keeping the cholesterol (膽固醇)within the egg emulsified(蛋白)．The egg yolk also contains biotin(維生素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(殼，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(直腸)，diverticulosis(瘢痕形成)，varicose veins(紋理)，phlebitis(靜脈炎)，and obesity．
FISH
Fish are excellent sources of high-grade protein, polyunsaturated fatty acids, and minerals, especially iodine(碘)and potassium(鉀)．Fish are categorized as freshwater fish, saltwater fish, and shellfish．These types differ slightly in nutritive value．Freshwater fish provide magnesium(鎂)，phosphorus, iron, and copper．Saltwater fish and shellfish are rich in iodine, fluorine(氟)，and cobalt (鈷)．Fatty fish, such as halibut(比目魚)，mackerel(鯖魚)，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(胡蘿卜素)，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(鎂)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．

話題鏈接：China's First Spaceman Yang Liwe
With a Long March-II-F carrier rocket(運載火箭)pushing Shenzhou Ⅴ into the orbit some 300 kilometers away from the Earth Wednesday morning, Yang Liwei, 38, turns out to be China's first astronaut in space．
At 9 am Wednesday(Beijing time), Yang, aboard Shenzhou Ⅴ white in color, took off from the Jiuquan Satellite Launch Center on the Gobi desert in northwest China's Gansu province．
He is expected to land somewhere on central Inner Mongolia grassland at 7 a.m．Thursday, after orbiting the earth 14 times．Yang will be traveling some 500 000 kilometers in space in 21 hours, a “traveler's record” in the world's most populous nation with a 5000-year-old civilization(文明)．
When Shenzhou-5 entered orbit on schedule, the ground command center received a message sent by Yang from outer space, saying that “everything goes smoothly”．His name, however, had remained unknown until 5 am Wednesday．At 5 am sharp Wednesday, Yang was seen waving his hands to a group of journalists from inside a glass-shielded(有防護玻璃的)room at the Jiuquan launch center, with two other astronauts sitting beside him as “backups”．Yang, who looked calm, found himself in a shower of camera flashlights．He responded with a broad smile．
In an exclusive(高級)interview with Xinhua, Yang expressed full confidence in China's first manned space flight．
Su Shuangning, director-general and chief designer of the astronaut system under China's manned space program, described Yang as a sober-minded(沉著冷靜的)person with a “superb capability of self-control”．
While a fighter pilot, Yang had 1350 hours of flight experience．He was chosen, along with 13 others, from among 1500 pilots for space flight training．Yang's colleagues described him as a man with a good team spirit, a man of dedication(奉獻) to his career．Friends at his hometown, Suizhong County of northeast China's Liaoning Province, remember that Yang had dreamed of flying when still a child．Yang was recruited(招募)by the No．2 Aviation College of the PLA Air Force in September 1983 and became a fighter pilot after graduation with bachelor's degree．In 1998, Yang became a member of China's first team of astronauts．Yang, 168 cm tall, is a lieutenant colonel．He has an eight-year-old son, and his wife, Zhang Yumei, also serves in China's space program．
According to Su Shuangning, China's first team of astronauts are all capable of working and living in space thanks to five years of rigid(嚴格的)physical, psychological and technical training．He said that Yang Liwei was one of the best in the team．
In an Astronaut Training Base in Beijing, China's would-be astronauts had lessons necessary for space flight, including aviation dynamics, air dynamics, geophysics, meteorology, astronomy, space navigation, design principle and structure of rockets and spacecraft, as well as equipment examination．Moreover, they received systematic(系統的)training in space flight in simulators(模擬器)．
“To establish myself as a qualified astronaut, I have studied harder than in my college years and have received training much tougher than for a fighter pilot, ” said Yang．
If the spaceship's re-entry module(模塊)could not land at the pre-set areas and the recovery team could not rush to the spot on time, the astronaut must act for self-rescue．“Therefore, survival skills have become one of the most important knowledge for the astronauts to grasp, ”said Su Shuangning．“Through rigorous(嚴酷的)training, our astronauts have learned how to survive under extreme conditions．”Twenty-five days before the launch of Shenzhou-5, the would-be astronauts started exercising in the real spacecraft at the Jiuquan Launch Center．
“When I boarded the spacecraft for the first time, I couldn't help feeling excited, ” Yang recalled．“I decided that I must fly it．”
At 6∶15 a.m．Wednesday, Yang got seated in the re-entry module of Shenzhou-5, atop a 58.3-meter-high Long March-II-F carrier rocket．Between 1999 and 2002, Long March-II-F carrier rockets were used to launch four unmanned spacecraft into orbit, and all the launches were successful．
想一想：After reading the passage, what made him become successful?What can you learn from him?

話題鏈接：近年來，隨著網絡的飛速發展，人們網上交流的日益頻繁，網上交友也日漸增多，網上交友到底如何？請看下文，然后想一想。
Friendship in InternetIn so many ways, cyberspace(網絡空間)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?

話題鏈接：中國中學生崇尚在發展自己興趣愛好的同時，還要勤奮學習，為將來上一所好的大學努力拼搏。那么，對于遠在大洋彼岸的美國中學生來說，他們的生活是否和我們相同呢？他們是否也和我們一樣在為上一所好大學而“一心只讀圣賢書”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(專攻)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(行為)．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(氣氛)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(收銀員)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．
美國的孩子自幼崇尚獨立，成人以后，大都不愿依靠父母來養活自己了。憑著自己的勞動換來的收入，很多學生不但能自己支付上學的各種費用，而且還可以養車、娛樂、買時髦衣服呢！讀讀他們的日常生活安排，你有什么感觸呢？
