[简答题] If a writer is going to write an article or other writings, he should go through some common stages in the writing process, from the preliminary(初步的) stage of brainstorming ideas all the way to the highly polished final draft, which is the last stage in writing before going to press.
After the initial stage of generating ideas, a rough plan or outline usually follows in the form of a mind map. This can then be transformed into the next stage, which is a more tightly structured written outline. At this point, the writer will now be ready to compose a rough or first draft.
The writer will then arrive at the revision stage of writing, and may ask for guidance or suggestions from other writers. After some deliberation the second draft is written in the subsequent stage. This in turn goes through to the final revision or proof-reading stage. After everything has been checked through carefully, the piece of writing reaches the final stage.

[填空题]
YAHOO was the first wonder of the web, and in many respects, it still is. It starts in January 1994 when two California graduate students, Jerry, Yang and David Filo, started compiling a database of links, mainly for their personal use. But well before the end of the year, it had become recognizable as the Yahoo we know today.
In the past seven years, Yahoo has expanded its range enormously, partly through a long string of acquisitions. Yahoo now offers almost everything you could want: e-mail, instant messaging, chat, clubs, photo albums, home web pages, file storage, shops, auctions, classified ads and more.

[单项选择]Science, in practice, depends far less on the experiments it prepares than on the preparedness of the minds of the men who watch the experiments. Sir Isaac Newton supposedly discovered gravity through the fall of an apple. Apples had been falling in many places for centuries and thousands of people had seen them fall. But Newton for years had been curious about the cause of the orbital motion of the moon and planets. What kept them in place Why didn’’t they fall out of the sky The fact that the apple fell down toward the earth and not up into the tree answered the question he had been asking himself about those larger fruits of the heavens, the moon and the planets.
How many men would have considered the possibility of an apple falling up into the tree Newton did because he was not trying to predict anything. He was just wondering. His mind was ready for the unpredictable. Unpredictability is part of the essential nature of research. If you don’’t have unpredictable things, you don’
