M: Dr. Martin, my name is Mark Johnson. My roommate, Benjamin Jones, is in your art history class.
W: Uhm Art History 5027
M: Yes. Well, he is sick and won't be in your class today. He asked me to bring his term paper to your office.
W: OK, the paper is due by 3 o'clock.
M: I have a class from 12. I'll bring it to your office after my class.
W: Well, I have a meeting this afternoon. So you can drop it off with the secretary of the art history department. She'll .see that I get it.
M: OK. I almost forgot. I'm a biology major. But my advisor told me that I need one more humanities course to graduate. I've noticed that you arc teaching a course on landscape painters next semester. Could you tell me a little bit about it？
W: Sure. Well, it's a course for nonart majors. We'll ha looking at several different painters and examining their works. We'll also look at the history and politics of the era in which they lived.
M: That sounds interesting. What else is required？
W: There is no final exam. And there is only one required book. But each student has to give a major presentation about an individual painter at the end of the course.
M: Hmm, it sounds good. Will you be in your office later today？ I'd like to talk to you some more.
W: Well, my meeting's scheduled to last all afternoon. Why don't you stop by tomorrow？ Any time in the afternoon. My office is in the fine arts building right next to the library.
M: Thanks. I'll do that.

A man who knows a bit about carpentry (木工术) will make his table more quickly than the man who does not. If the instructions are not very clear, or the shape of a piece is puzzling his experience helps him to conclude that it must fit there, or that its function must be that. In the same way, the reader's sense and experience helps him to predict what the writer is likely to ,say next; that he must be going to say this rather than that. A reader who can think along with the writer in this way will find the text.
This skill is so useful that you may wish to make your students aware of it so that they can use it to tackle difficult texts. It does seem to be the case that as we read we make hypotheses (假设) about what the writer intends to say; these are immediately modified by what he actually does say, and are replaced by new hypotheses about what will follow. We have all had the experience of believing we were understanding a text until suddenly brought to a halt by some word or phrase that would not fit into the pattern and forced us to reread and readjust our thoughts. Such occurrences lend support to the notion of reading as a constant making and remaking of hypotheses.
If you are interested in finding out how far this idea accords with (符合) practice, you may like to try out the text and questions. To do so, take a piece of card and use it to mask the text. Move it down the page, revealing only one
t a time. Answer the question before you go on to look at the next section. Check your prediction against what the text actually says, and use the new knowledge to improve your next prediction. You will need to look back to earlier parts of the text if you are to make accurate prediction, for you must keep in mind the general organization of the argument as well as the detail within each sentence. If you have tried this out, you have probably been interested to find how much you can predict, though naturally we should not expect to be right every time -- otherwise there would be no need for us to read.
Conscious use of this technique can be helpful when we are faced with a part of the text that we find difficult: if we can see the overall pattern of the text, and the way the argument is organized, we can make a reasoned guess at the next step. Having an idea of what something might mean can be a great help in interpreting it.
The author uses the examples of carpentry and reading to show______.
A．the importance of making prediction
B．the similarity in using one's senses
C．the necessity of making use of one's knowledge
D．the most effective method in doing anything
第7题
Oil prices have raised overall consumer prices and cut into household purchasing power. So far the higher costs haven't deterred(阻止) buying, even buying of cars and other energy-sensitive items. The major reason for the lack of reaction is that oil is less important to the economy than it once was. Oil, which produced 45% of world energy in 1971, accounted for only 35% in 2003, with increases in nuclear and natural gas use making up the difference.
GM, Ford, and Chrysler suffered as buyers shifted to more fuel-efficient vehicles from Toyota and Honda, but the shift was hot pronounced. Admittedly, light truck sales are holding up in part because manufacturers are offering large discounts to "move the metal", but the fact that buyers are responding to those incentives shows they aren't too scared of gas prices.
Americans continue to spend more than they earn, but gasoline prices will have an effect. Although the April chain store results suggest gasoline prices aren't hurting much yet, eventually Americans will be forced to realize that they have to slow down. We expect the economy to slow in the second half of the year as the impact of higher oil prices sinks in. How much the economy slows will depend on how high oil prices remain. We expect some drop in oil prices by yearend, but I have been saying that for so long even I am starting not to believe it.
The anger against the oil companies is clearly misplaced. Exxon and friends control only a small share of world oil reserves. Most are now in the hands of state-owned oil companies. The recent move by Bolivia to nationalize its industry is only the latest in a long line of similar actions. The history of these enterprises is one of severe underinvestment and mismanagement, which tends to reduce supply and keep prices high. The risk on oil prices is primarily on the high side of our forecast.
Although I think oil prices will drop back in the medium term, to address my serious worries, I'm buying my wife a bike for Mothers' Day.
The economy at the beginning of 2006 is not affected by the high oil price mainly because ______.
A．the warm winter requires less oil to run the heaters
B．the warm winter promotes consumption, across the country
C．people believe that the oil price will drop in near future
D．people don't think the high price will make much of a difference
