She'll give you your course number and timetable and explain where the various classrooms are, what books you'll need, and whether they are available in the library. Besides, she'll give you detailed information about how you are scored. If books are not available in the library, you can try in the bookstore. Our book store is next to the reception in the main hall. It's open from 9 to 10 a.m. daily. Now about meals breakfast 8: 30 to 9, full evening meal 6: 30 to 8: 30 in the dining room.

If you look at the notice board in the main hall, you'll see that we have arranged a variety of evening entertainments for you, and Saturday excursions.

I hope you'll all have a very enjoyable time, and make a lot of new friends. Margery Hooper is _______. A．at a music conference B．on a holiday course C．at a holiday resort D．on a training course

The only solid piece of scientific truth abut which I feel totally confident is that we are profoundly ignorant about nature. Indeed, I regard this as the major discovery of the past hundred years of biology. It is, in its way, an illuminating piece of news. It would have amazed the brightest minds of the 18th. century Enlightenment to be told by any of us how little we know and how bewildering seems the way ahead. It is this sudden confrontation with the depth and scope of ignorance that represents the most significant contribution of the 20th century science to the human intellect. In earlier times, we either pretended to understand how things worked or ignored the problem, or simply made up stories to fill the gaps. Now that we have begun exploring in earnest, we are getting glimpses of how huge the questions are, and how far from being answered. Because of this, we are depressed. It is not so bad being ignorant if you are totally ignorant; the hard thing is knowing in some detail the reality of ignorance, the worst spots and here and there the not-so-bad spots, but no true light at the end of the tunnel nor even any tunnels that can yet be trusted. But we are making a beginning, and there ought to be some satisfaction. There are probably no questions we can think up that can' t be answered, sooner or later, including even the matter of consciousness. To be sure, there may well be questions we can't think up and therefore limits to the reach of human intellect, but that is another matter. Within our limits, we should be able to work our way through to all our answers, if we keep at it long enough, and pay attention. According to the author, really good science ______. A．would surprise the brightest minds of the 18th century Enlightenment B．will help people to make the right choice in advance C．will produce results which cannot be foreseen D．will bring about disturbing results

Revising can be described as the most important(and frequently most neglected) part of writing. Novelists Doris Lessing has said that many novels miss greatness because authors are unwilling or unable to revise them. James Michener explains the importance of revision this way: "I have never thought of myself as a good writer. Anyone who wants reassurance of that should read one of my first drafts. But I' m one of the world' s great revisers." Revising takes many forms. It means thinking about the audience for your writing. Who will read your work and why？ It also means developing an overall plan for the writing that will make your ideas clear. Often the organization of a first draft will reflect your process of discovery, but that may not be the best way to present your ideas to someone else. Revising also gives attention to the style. of language, to the structure of a paragraph, and to the shape of sentences and other forms that show learning to its best advantage. Writing to learn and writing to show learning are never, of course, entirely separate processes. Writers frequently consider issues of demonstrating learning while writing to learn, and writing to show learning often leads to new under- standings. In drafting, for example, you may start thinking about what an audience will need to know in order to under- stand your point and change a word or a phrase to make your meaning clearer. But understanding the differences between writing to learn and writing to show learning is central to seeing writing as a process. What Doris Lessing said helps to support the idea that______. A．he is one of the world' s great revisers B．he is not a good writer C．revising is very important D．many writers are unwilling to revise their works
