单选题Space is a dangerous place, not only because of meteors (流星) but also because of rays from the sun and other stars. The atmosphere again acts as our protective blanket on earth. Light gets through, and this is essential for plants to make the food which we eat. Heat, too, makes our environment endurable. Various kinds of rays come through the air from outer space, but enormous quantities of radiation (辐射) from the sun are screened off. As soon as men leave the atmosphere they are exposed to this radiation but their spacesuits or the walls of their spacecraft, if they are inside, do prevent a lot of radiation damage. Radiation is the greatest known danger to explorers in space. The unit of radiation is called "rem". Scientists have reason to think that a man can put up with far more radiation than 0.1 rem without being damaged; the figure of 60 rems has been agreed on. The trouble is that it is extremely difficult to be sure about radiation damage—a person may feel perfectly well, but the cells of his or her sex organs may be damaged, and this will not be discovered until the birth of deformed (畸形的) children or even grandchildren. Missions of the Apollo flights have had to cross belts of high radiation and, during the outward and return journeys, the Apollo missions have been quite short. We simply do not know yet how men are going to get on when they spend weeks and months outside the protection of the atmosphere, working in space laboratory. Rugs might help to decrease the damage done by radiation, but no really effective ones have been found so far.

单选题Most mothers have a good piece of advice: Never go into a supermarket hungry! If you go shopping for food before lunch time, you"ll probably buy more than you plan to. Unfortunately, however, just this advice isn"t enough for consumers these days. Modern shoppers need an education on how and how not to buy things at the grocery store. First, you should check the weekly newspaper ads. Find out the items that are on sale and decide if you really need those things. In others words, don"t buy anything just because it"s cheaper than usual! "New and Improved!" or" All natural" on the front of a package influences you. Instead, read the list of ingredients (成分) on the back. Third, compare prices; that is, you should examine the prices of both different brands and different sizes of the same brand. Another suggestion for consumers is to buy genetic (普通的) items instead of famous brands. Genetic items in supermarkets come in plain packages. These products are cheaper because manufacturers don"t spend much money on packing or advertising. The quality, however, is usually identical to the quality of well-known name brands. In the same way, in buying clothes, you can often find high quality and low prices in brands that are not famous. Shopping in discount clothing stores can help you save a lot of money. Although these stores aren"t very attractive, and they usually do not have individual dressing rooms, not only are the prices low, but you can often find the same famous brands that you find in high-priced department stores. Wise consumers read magazine advertisements and watch TV commercials, but they do this with one advantage: knowledge of the psychology behind the ads. In other words, well-informed consumers watch for information and check for misinformation. They ask themselves questions: Is the advertiser hiding something in small print at the bottom of the page? Is there any real information in the commercial, or is the advertiser simply showing an attractive image? With the answers to these questions, consumers can make a wise choice.
