单选题The market investigation is indispensable to sales promotion. They are as closely related as the lips and teeth, so to speak. What you produce is for sale on the market. It would be impossible to succeed in selling a product without first investigating the market. In the international market, goods on sale coming from countries and suppliers are always facing keen competition. Under such circumstances, they will try everything possible to familiarize themselves with the market conditions. (9) In making investigations, we ought to get information about what similar items the competitors are offering on the market, what prices they are quoting (报价), what features their products have, who their regular customers are, etc. Then, how can we obtain such information? There are many channels that we can make use of in doing this sort of work. The commercial counselor's offices of our embassies stationed abroad can help us in making market investigations. Nowadays, our import and export corporations send their trade groups abroad every no wand then. One of their purposes is to make market surveys on the spot. Certainly, ace-to-face talks with foreign businessmen are also important channels to get market information. The Chinese Export Commodities Fairs and some other fairs of similar nature as well as visits of foreign businessmen provide us with such opportunities. Of course, there are some other ways of making market investigations.

单选题To swim across the English Channel takes at least nine hours. It"s a hard work and it makes you short of breath. To fly over the Channel takes only twenty minutes (as long as you"re not held up at the airport), but it"s an expensive way to travel. You can travel by hovercraft if you don"t mind the noise, and that takes forty minutes. Otherwise you can go by boat, if you forget your sea-sickness ills. All these means of transport have their problems and the weary (不耐烦的) traveler often dreams of being able to drive to France in his own car. "Not possible", you say. Well, wait a minute. People are once again considering the idea of a Channel tunnel or bridge. This time, the Greater London Council is looking into the possibility of building a Channel link straight to London. A bridge would cost far more than a tunnel, but you would be able to go by rail or by car on a bridge, whereas a tunnel would provide a rail link only. Why is this idea being discussed again? Is Britain becoming more conscious of the need for links with Europe as a result of joining the EEC (欧共体)? Well, perhaps. The main reason, though, is that a tunnel or bridge would reach the twenty square kilometers of London"s disused dockland (船坞地). A link from London to the continent would stimulate trade and re-vitalize (使…重新有活力) the port, and would make London a main trading centre in Europe. With a link over the Channel, you could buy your fish and chips in England, and be able to eat them in France while they were still warm!
