Some researchers think that it comes down to the structure of the food, not its chemical composition a finding that could help rid some processed foods of chemical preservatives. Cream and butter contain much【 B1】

18、_, so why cream should sour much faster has been a 【 B2】 _. Both are emulsions tiny globules of one liquid evenly【 B3】 _throughout another. The difference lies in whats in the globules and whats in the surrounding. In cream, fatty globules 【 B4】 _ in a sea of water. In butter, globules of a watery【

19、B5】 _are locked away in a sea of fat. The bacteria which make the food go bad prefer to live in the watery regions of the【 B6】 _. This means that in cream, the bacteria are free to grow throughout the mixture. When the situation is 【 B7】 _, the bacteria are locked away in【 B8】 _buried deep in the se

20、a of fat. Trapped in this way,【 B9】 _colonies cannot spread and rapidly run out of nutrients. They also slowly poison themselves with their waste products. In butter, there is a self-limiting system which stops the bacteria growing. The researchers are already working with food companies keen to see

21、 if their products can be made【 B10】 _bacterial attack through alterations to the foods structure. They believe that it will be possible to make the emulsions used in salad cream, for instance, more like that in butter. The key will be to do this while keeping the salad cream liquid and not turning

Through the video conferencing, not only your voice but also your face, the surroundings

23、and any other graphic and physical【 C1】 _can be captured and transmitted through the communication system with or without wires. Of course, when you go into the details, the technology involved is very【 C2】 _ and the subject matter littered with jargon. Such as ISDN(Integrated Services Digital Netwo

The engine stalls out at lights, holds back as you go to pass. It needs a tune-up and soon. Where do you go? The library. You can take out an auto repair manua

29、l that tells step-by-step how to tune up your make and model. Or your tennis game has fallen off. Youve lost your touch at the net. Where do you go? The library for a few books on improving your tennis form. B)“The library!“ you say. “Thats where my teacher sends me to do ugh home work. “Unfortunate

30、ly, Ive found thats exactly the way many people feel. If youre among them, youre denying yourself the easiest way to improve yourself, enjoy yourself and even cope with life. My first suggestion for making the most of your library is to do what I did, read and read and read. For pleasure and for und

31、erstanding. C)If its TV that keeps you from cultivating this delicious habit, I can offer a sure remedy. Take home from the library a stack of books that might look interesting. Pile them on the TV set. Next time you are tempted to turn on a program you really dont want to see, reach for a book inst

32、ead. D)Over the years, people collect a mental list of books they mean to read. If you dont have such a list, here is the suggestion. Take from the library some of the books you might have enjoyed dramatized on TV, like Remargues All Quiet on the Western Front, Clavells Shogun, Tolkiens The Hobbit,

33、or Victor Hugos Les Mise Rabies. If you like what you read, you can follow up with other satisfying books by the same authors. E)Some people in their reading limit themselves to current talked-about best sellers. Oh, what they miss! The library is full of yesterdays best sellers; and they still make

34、 compelling reading today. Some that Ive enjoyed: A. B. Guthries The Big Sky, Carl Van Dorens Benjamin Franklin, Mari Sandozs Old Jules, and Norman Mailers The Naked and the Dead. F)How do you find these or any other books youre looking for? Its easy with the card catalog. Every time I go to the lib

35、rary and I go more than once a week I invariably make a beeline to the card catalog before anything else. Its the nucleus of any public library. The card catalog lists every book in the library by: 1. author; 2. title; 3. subject. Lets pick an interesting subject to look up. I have always been fasci

36、nated by astronomy. Youll be surprised at the wealth of material you will find under “astronomy“ to draw upon. And the absorbing books you didnt know existed on it. CAUTION: Always have a pencil and paper when you use the card catalog. G)Once you jot down the numbers of the books you are interested

37、in, you are ready to find them on the shelves. Libraries call the shelves “the stacks“. In many smaller libraries, which youll be using, the stacks will be open for you to browse. To me there is a special thrill in tracking down the books I want in the stacks! For invariably, I find books about whic

38、h I knew nothing, and these often turn out to be the very ones I need. You will find the same thing happening to you when you start to browse in the stacks. “A learned mind is the end product of browsing.“CAUTION: If you take a book from the stacks to your work desk, do not try to return it to its p

39、roper place. Thats work for the experts. If you replace it incorrectly, the next seeker wont be able to find it. H)Some of the brightest and best-informed men and women in America are the librarians who specialize in providing reference help. Introduce yourself. State your problem. And be amazed at

40、how much help you will receive. CAUTION: Dont waste the time of this expert by asking silly questions you ought to solve yourself. Save the reference librarian for the really big ones. I)You should also learn to use the Reader s Guide to Periodical Literature .This green-bound index is one of the mo

41、st useful items in any library. It indexes all the articles in the major magazines, including newspaper magazine supplements. Thus it provides a guide to the very latest expert information of any subject that interests you. So if you want to do a really first-class job, find out which magazines your

42、 library subscribes to, then consult the Reader s Guide and track down recent articles on your subject. When you use this wonderful tool effectively, you show the mark of a real scholar. J)Since you can take most books home, but not magazines, take full notes when using the latter. Many libraries to

43、day provide a reprographic machine that can quickly copy pages you need from magazines and books. Ask about it. If you are working on a project of some size which will require repeated library visits, keep a small notebook in which you record the identification numbers of the books you will be using

44、 frequently. This will save you valuable time, because you wont have to consult the card catalog or search aimlessly through the stacks each time you visit for material you seek. Some of the very best books in any library are the reference books, which may not be taken home. Learn what topics they c

45、over and how best to use them, for these books are wonderful repositories(储藏室、资料库 )of human knowledge. K)Your library can give you help on any subject. It can even be your business and legal advisor. How many times have you scratched your head over how to get a tax rebate(折扣 )on your summer job? You

46、ll find guides to that. Want to defend yourself in traffic court? Find out how in legal books at the library. L)Library Projects Can Be Fun and Rewarding. Here are a few ideas: 1. What are your roots? Trace your ancestors. Many libraries specialize in genealogy. 2. Did George Washington sleep nearby

47、? Or Billy the Kid? Your librarys collection of local history books can put you on the trail. 3. Cook a Polynesian feast. Or an ancient Roman banquet. Read how in the librarys cook books. 4. Take up photography. Check the library for consumer reviews of cameras before you buy. Take out books on ligh

48、ting, composition, or darkroom techniques or you name it! M)If you havent detected by now my enthusiasm for libraries, let me offer two personal notes. Im particularly pleased that in recent years two beautiful libraries have been named after me: a small community library in Quakertown, Pennsylvania

49、, and the huge research library located at the University of Northern Colorado in Greeley. And I like libraries so much that 1 married a librarian. 47 The nucleus of any public library is the card catalog. 48 Yesterdays best sellers are still good for reading, which shouldnt be overlooked. 49 The author suggests that people should go to the library for answers when things go wrong. 50 The Readers Guid
