There are several factors that contribute to wisdom. Of these I should put first a sense of proportion: the capacity to take account of all the important factors in a problem and to attach to each its due weight. This has become more difficult than it used to be owing to the extent and complexity of the special knowledge required of various kinds of technicians. Suppose, for example, that you are engaged in research in scientific medicine. The work is difficult and is likely to absorb the whole of your mind. You have no time to consider the effect which your discoveries or inventions may have outside the field of medicine. You succeed (let us say) as modern medicine has succeeded, in enormously lowering the infant death-rate, not only in Europe and America, but also in Asia and Africa. This has the entirely unintended result of making the food supply inadequate and lowing the standard of life in the parts of the world that have the greatest populations. To take an even more dramatic example, which is in everybody’s mind at the present time; you study the makeup of the atom from a disinterested (无利害关系的) desire for knowledge, and by chance place in the hands of a powerful mad man the means of destroying the human race.
Therefore, with every increase of knowledge and skill, wisdom becomes more necessary, for every such increase augments (增强) our capacity for realizing our purposes, and therefore augments our capacity for evil, if our purpose are unwise.
第31题：Disagreement arises when people try to decide ________.
A) how much more wisdom we have now than before
B) what wisdom is and how to develop it
C) if there is a great increase of wisdom in our age
D) whether wisdom can be developed or not
第6题
M: Well, there's good news for buyers. Prices won't increase. In fact, they'll fall slightly. There are different reasons for this. One is that it won't be so easy to borrow money. A second reason is that there are still a lot of empty new houses on the market.
W: I see. And what about food prices？ Will they fall too？
M: I'm afraid not. You see, inflation will increase, so consumer prices will rise too. I think we can expect a 3% rise in prices.
W: Some economists say that unemployment will rise. Are you one of these people？
M: No, I'm not. I think it'll decrease. Trade with other countries has improved dramatically over the past year. And the increase in demand for goods means that there will be more jobs.
W: Well, if unemployment falls, can we expect wages to fall too？
M: No, no. The average wage will increase. Not very much, I'm afraid, but there will be a slight increase.
W: One financial question, Mr. Green. What will happen to petrol prices？ Will they increase or decrease next year？
M: That's a very difficult question to answer because we don't know what'll happen in the oil producing countries. I have a feeling that prices will go down. However, I could be wrong!
W: Mr. Green, thank you very much for your time.
M: My pleasure.
(20)
A．Housing costs.
B．Average wage.
C．Unemployment.
D．Oil prices.

Should You Jump on the Technological Bandwagon (时尚)？
Technological Advances and Their Influence
Within the last 20 years, we have been swamped with new technology which has helped us run our businesses faster, and hopefully better. Recently, some of us have begun to question whether the onslaught of ever newer technology is really helping us as much as the initial improvements did. Just because a technology is new doesn't necessarily mean that it is better. Perhaps what we should be asking is "What technology can we really use？"
We all have some hi-tech products that we've bought but don't use. Many of us have a VCR with so many complex functions that we have difficulty programming it to record a program. Similarly, we have seen workers spend an hour playing with a computer program to print out a single mailing label which could have been more quickly done on a typewriter.
Every business may not be able to afford all of these new toys. And they may not need to. Remembering that in many cases the pushers of new technology are simply salespeople trying to get you to pay for the toys which intrigue them. There are several questions you should ask yourself before making any decision: How much are these toys really worth？ Does this new technology make sense for your business？ Is this technology really worth the effort needed to use it？ With any new technology, there is a payback time when the increased efficiency gained may help to pay for the adoption of that new technology. When you first computerized your office, you got a big boost in efficiency for a minimal investment. As the technology gets ever more sophisticated, you start to lose that increase in efficiency. The old saying goes that you get 90% of your increase in efficiency for 10% of your investment. The remaining 90% of your money is spent trying to get that last 10% increase in efficiency. You have to analyze your business and decide if you ever get enough increase in efficiency to pay back that large additional cost.
New Technologies and Their Cost
You need to analyze the way you do business to see what you can do to increase your efficiency. You can't get caught in the trap of "WE' VE ALWAYS DONE IT THIS WAY !" You want to keep the best, and throw away the things that slow you down. Sometimes that does mean adopting new technology. Sometimes it means changing the way you do business. Sometimes it means keeping what you have.
Let's consider and analyze some of the new technologies.
？Internet Presence
The Internet is receiving a lot of hype (炒作) these days, and it sounds as though every business needs to have an Internet presence. Developing and maintaining a website takes time and money.. Before you make that investment, you should decide if you really need an Internet presence. Ask yourself these questions: Are your potential clients located throughout the United States？ Do your potential clients own computers？ Are your potential clients computer sophisticates who surf the Web regularly？ Are the people who ARE on the Internet part of your potential client base？ (The primary users of the Internet at this time tend to be educated, middle to upper middle class people.)
If you can answer yes to all of these questions, then an Internet presence may make sense for your business. If your potential clients are all local, if they have little or no access to the Internet, then this technology may be one you can play with, as long as you recognize that the expenses will not necessarily increase your business.
？Paperless Office
A paperless office is one in which all records are kept only in the computer. To many people, this appears to be a good idea. No paper files are kept, so no time is spent filing. However, time is still needed to scan information into the computer, correct it, etc. More importan
A．Y
B．N
C．NG

听力原文：W: Hi, Sam, I hate to bother you but I wonder if I could have a word with you？
M: Sounds so serious. What's up？
W: Well, the landlord just informed me that he's going to increase our rent by two hundred. I'm wondering how you feel about it.
M: How do I feel about it？ No way! In the rental agreement, it says he will have to give us a notice three months in advance if he wants to increase the rent.
W: Yeah, that's right! It's gotta be three months later. Well, I think he realizes his rental fee is below the market rate and he must be feeling a bit ripped off when he could be charging a couple hundred extra. What do you think, Sam？ Should we agree to the raise or find somewhere else？
M: Good question. I'm not sure either. The location we're at now is quite convenient, close to the grocery and near the subway. It'll be hard to find another location like this one.
W: I wonder whether he'll allow room for negotiation, perhaps a hundred dollars instead of two. Maybe he might be more willing to give a bit if we speak to him right away.
M: Well, he seems to be a nice guy to talk to. But what if he refuses？ Would you go for two then？ W: Well, I guess I would, since it'll be hard to find such a convenient location. Besides, it's close to my school and I can sleep a little later in the mornings.
M: Ha! I figured that's what you'd be concerned about. Well, I have to give it some serious thought. I'm not sure I can afford to cough up an extra hundred a month just to make sure I can sleep in an extra 15 minutes.
W: Didn't you get your loan recently？ That'll cover what you need. Besides, if you could just stop spending so much on cafeteria snacks you'd have lots of money to spare.
M: Yeah, but I'm thinking of getting a new laptop.
W: Well, I tell you, there aren't a lot of apartments that are cheaper, even with this new increase.
M: I know, so when does he want us to come back on this？
W: He told me to let him know this weekend.
M: Sure, by then I should be able to make up my mind.
