___46___ to the researchers, there is only one chance in a hundred that their findings could be explained by chance alone. Lead author Dr Beatrice Golomb, from the University of California at San Diego, said: "Our findings appear to add to a body of information suggesting that the composition of calories, not just the number of them, matters for determining their ultimate impact on weight."This is not the first time scientists ___47___ that chocolate may be healthy for us. Other studies have claimed chocolate may be good for the heart.

of their own. The student who is writing a composition, the businessman who is writing a report, and the housewife who is preparing a talk for a woman`s club often need the kind of information they find in 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 copy 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 that paragraph. Note-taking also helps you to remember what you have read. It is much easier to remember what you have said in a note that someone else has said in a book. Even if author`s vocabulary is easily understood, it isn`t the vocabulary you naturally think of. Putting his ideas into your vocabulary makes those ideas yours, and yours are the ideas you best remember. 4. 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-taking 5. writing that you will do. Notes that make you think as you write are better than notes that merely help you 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.” |
