he influence of geography and climate on the psychological and physical health of humankind. There seems no doubt that the general character of landscape, the relative length of day and night, and climate must all play a part in determining what kind of people we are.

It is true that a few studies have been made. Where all the inhabitants of a particular area enjoy exceptionally good or bad health, scientists have identified contributory factors such as the presence or absence of substances like iodine, fluoride, calcium, or iron in the water supply, or perhaps types of land that provide breeding places for pests like mosquitoes or rats.

Moreover, we can all generalize about types of people we have met. Those living in countries with long dark winters are apt to be less talkative and less lively than inhabitants of countries where the climate is more equable(稳定的). And where olives and oranges grow, the inhabitants are cheerful, talkative, and casual.

But these commonplace generalizations are inadequate—the influence of climate and geography should be studied in depth. Do all mountain dwellers live to a ripe old age？ Does the drinking of wine, rather than beer, result in a sunny and open character？ Is the strength and height of a Kenyan tribe due to their habitual drinking of the cow blood？

We are not yet sure of the answers to such questions, but let us hope that something beneficial to humankind may eventually result from such studies.

The author's purpose of writing this passage is to ______.

A．alert readers to the scarcity of natural resources

B．call for more research on the influence of geographical environment

C．introduce different elements in character cultivation

D．draw more attention to the health condition of mankind

some deals with you soon．

Zhang: Mr． George, we are pleased to have the opportunity to meet you here in our company． After you have seen the presentations in our show room, would you tell me which particular items are really of interest to you？

George: I had studied your catalogue before I saw your presentations in the show room． We are interested in your silk dresses． I think there will be a prospective market for some of them in AmericA．Here is a list of our requirements, for which I hope to have your lowest offer, CIF New York．

Zhang: Thank you for your inquiry． Could you please let us know the quantity you require so that we can make the offers？

George: I'll do that． Meanwhile, would you give me an indicative price？

Zhang: SurE．Here are our FOB price lists． All prices in the lists are subject to our final confirmation． You will find the prices are reasonable．

George: What about the commission？

Zhang: Usually, our principle does not allow any commission．

George: From European suppliers, in the regular practice, we usually get a 3 to 5 percent commission for imports． You know, we do business on commission basis． Moreover, a commission will help us to promote sales．

Zhang: Well, if the order is really large enough, we may take the commission into consideration． I think it will be better to consult this when you order the goods．

George: OK． Then I will write down the quantity for each item on the enquiry list． Can you tell me when we can have your offer？

Zhang: Tomorrow morning． Could we meet again tomorrow afternoon for further details？

George: Fine．

Counter-offer

Joe, the representative of the buyer, is at Mr．Liang's office, discussing the offer with Mr．Liang.

Joe: Mr．Li, Thank you for your prompt offer．I have studied your offer carefully and consulted our home office．After investigating and comparing, we found that your price is about 5 percent higher than those offered by European Suppliers.

Liang: I hope you also should consider the quality of the goods as well．I'm sure you know very well that our product is made of pure silk．This, of course, increases the cost but promises the superior quality.

Joe: I will agree with you about the importance of quality．But 5 percent is a big difference which we can't not accept because that will leave us little benefit in the intense competition on the world market.

Hang: We can give you a 2 percent discount if your quantity can be adjusted up to 10 000 pieces．And we have confidence that even your selective customers will be satisfied with the fashionable design and superb quality of our goods.

Joe: I am afraid 2 percent is not enough for us to open a new market for your products．We believe 4 percent at least will make your product more competitive.

Liang: I'm afraid we can't give 4 percent reduction by all means．Considering you are a new customer, a 3 percent reduction is really the best we can do.

Joe: Well, Mr．Li, does this price include seaworthy packing？

Liang: The outer packing is for container transportation．That is the usual practice.

Joe: How long will this offer be valid？

Liang: Within one week.

Joe: I'll try to persuade our head office to accept the price with 3 percent discount and inform you of the answer at an early date.

Hang: We will await your good reply.
