题型：单项选择题 阅读理解。 根据短文内容，从下框A~F选项中选出能概括每段主题的最佳选项。选项中有一项为多余项。A. How to take notes and rewrite in one`s own wordsB. Advantages of taking notes C. Taking some useful notes D. Taking notes is a help to create new ideas in the futureE. Need to change information from an encyclopedia into one`s ownF. Two ways of writing a note and their advantage1. In school and out, many people need to put the information they find in an encyclopedia into wordsof their own. The student who is writing a composition, the businessman who is writing a report, andthe housewife who is preparing a talk for a woman`s club often need the kind of information they findin an encyclopedia. But no one wants what he writes to read as it were copied from an encyclopedia.What you write should read as if it came from you.2. Even if you have every intention of rewriting the material in your own words, it is unwise to copyinformation from an encyclopedia word for word. Instead, write brief notes to remind yourself of thefacts you wish to express. Later with the encyclopedia closed, you can expand those notes into sentences and paragraph of your own.3. The advantage of note-taking over copying is that it forces you to think for yourself at least twice-first when you are reading and second when you are using your notes. It is easy to copy a paragraph without being sure of what it means. But to make a note expressing the meaning of a paragraph in your own words requires you to prove to yourself that you have understood thatparagraph. Note-taking also helps you to remember what you have read. It is much easier toremember what you have said in a note that someone else has said in a book. Even if author`svocabulary is easily understood, it isn`t the vocabulary you naturally think of. Putting his ideas intoyour vocabulary makes those ideas yours, and yours are the ideas you best remember.4. Some people write notes in complete sentences. Others write notes that are phrases of topics. For example, a sentence note on the paragraph above might be “Notes help you remember.”A topical note for the same paragraph might be “Notes as memory helps”. Both of these are four-word notes, and therefore either has an advantage to save time at the moment of note-taking5. Remember that the purpose of taking notes is always for some future use, often for some futurewriting that you will do. Notes that make you think as you write are better than notes that merely helpyou remember information. The thinking writer is the one who creates something new, something that no one can point to and say, “Oh, I have seen that same paragraph in an encyclopedia.” 查看答案
