单选题There are advantages in 1997, if you want to look for them. The air is cleaner, and there seem to be fewer colds. The crime rate has dropped. With the police car too expensive, policemen are back on their beats. More important, the streets are full. Legs are king, and people walk everywhere far into the night. There is mutual protection in crowds. If the weather isn't too cold, people sit out front. If it is hot, the open air is the only air-conditioning they get. At least, the street lights still burn. Indoors, few people can afford to keep lights burning after supper. As for the winter--well, it is inconvenient to be cold, with most of what furnace fuel is allowed hoarded for the dawn. But sweaters are popular indoor wear. Showers are not an everyday luxury. It is sore in the suburbs, which were born with the auto, lived with the auto, and are dying with the auto. Suburbanites from associations that assign turns to the procurement and distribution of food. Rushcarts creak from house to house along the posh suburban roads, and every bad snowstorm is a disaster. It isn't easy to hoard enough food to last till the roads are open. What energy is left must be conserved for agriculture. The great car factories make trucks and farm machinery almost exclusively. The American population isn't going up much any more, but the food supply must be kept high even though the prices and difficulty of distribution force each American to eat less. Food is needed for export to pay for some trickles of oil and for other resources. The rest of the world is not as lucky as we are. They're starving out there because earth's population has continued to rise. The population on earth is 5. 5 billion--up by 1.5 billion since 1997--and outside the United States and Europe, not more than one in five has enough to eat at any given time. There is a high infant mortality rate. It's more than just starvation, though. There are those who manage to survive on barely enough to keep the body working, and that proves to be not enough for the brain. It is estimated that nearly two billion people in the world are permanently brain damaged by undernutrition, and the number is growing. At least, the big armies are gone. Only the United States and the Soviet Union can maintain a few tanks, planes, and ships--which they dare not move for fear of biting into limited fuel reserves. Machines must be replaced by human muscle and beasts of burden. People are working longer hours, and with lighting restricted, television only three hours a night, new books few and printed in small editions--what is there to do with leisure? Work, sleep, and eating are the great trinity of 1997, and only the first two are guaranteed.

单选题Most countries in the world now welcome tourists because of the money they bring in. Many countries make great efforts to encourage tourism, and many also depend on what they earn from it to keep their economies going. People who like adventure will even try to visit countries where travel is difficult and costs are high. Companies regularly arrange trips throughout the Sahara desert, or to the Himalayan Mountains for whoever enjoys such trips, but the numbers of visitors are small. Most tourists try to choose whichever places have fairly comfortable, cheap hotels, quite good food, reasonable safety, sunny weather and plenty of amusements or unusual things to see. Their choice of a place for a holiday also depends very much on when they can get away; it is not very pleasant to go to a place when it is having its worst weather. One of the big problems for a nation wishing to attract a lot of tourists is the cost of building hotels for them. Building big hotels swallows up a lot of money, and many of the countries that need the tourists are poor. What they spend on building has to be borrowed from foreign banks. And sometimes the money they can afford to borrow produces only chains of ugly hotels wherever there are beauty spots that are supposed to attract the tourists. Another problem is that more and more big international companies are building hotels all over the world, so that the profits from a hotel often do not stay in the country in which it has been built. And there is also the question of training staff; teaching them foreign languages, how to cook the kind of food that the foreign tourists expect, and so on. In many countries, special colleges and courses have been set up for this. Crime can also be a problem. Seeing tourists who seem to be much richer than them selves, the local inhabitants are often tempted to stem from them. Sometimes tourists resist and get killed, and then other tourists refuse to come to the country. But an even greater problem in many countries is the effect that the sight of foreigners has on the local population. A man who lives in a very small house, owns almost nothing, works very hard for his living and has very strong roles about modesty in dress and not drinking alcohol sees foreign tourists rejoicing in what to him is great luxury, owning radios, wearing very few clothes and drinking a lot of beer. These tourists may be ordinary workers back home, but to the poor inhabitant they seem to be very rich. And of course, he either feels envy for them or thinks them shameless. Tourists, too, often feel shocked by the different customs and habits that they see around them. They refuse the local food, and insist on having only what they eat back home. They say that travel broadens the mind; but it is doubtful whether this is so, often, it narrows it.
