Avoid the rush-hour' must be the slogan of large cities the world over. If it is, it's a s

logan no one takes the least notice of. Twice a day, with predictable regularity, the pot boils over. Wherever you look it's people, people, people. The trains which leave or arrive every few minutes are packed: an endless procession of human sardine tins. The streets are so crowded, there is hardly room to move on the pavements. The queues for buses reach staggering proportions. It takes ages for a bus to get to you because the traffic on the roads has virtually come to a standstill. Even when a bus does at last arrive, it's so full, it can't take any more passengers. This whole crazy system of commuting stretches man's resources to the utmost. The smallest unforeseen event can bring about conditions of utter chaos. A power-cut, for instance, an exceptionally heavy snowfall or a minor derailment must always make city-dwellers realise how precarious the balance is. The extraordinary thing is not that people put up with these conditions, but that they actually chose them in preference to anything else.

Large modern cities are too big to control. They impose their own living condition on the people who inhabit them. City-dwellers are obliged by their environment to adopt a wholly unnatural way of life. They lose touch with the land and rhythm of nature. It is possible to live such an air-conditioned existence in a large city that you are barely conscious of the seasons. A few flowers in a public park (if you have the time to visit it) may remind you that it is spring or summer. A few leaves clinging to the pavement may remind you that it is autumn. Beyond that, what is going on in nature seems totally irrelevant. All the simple, good things of life like sunshine and fresh air are at a premium. Tall buildings block out the sun. Traffic fumes pollute the atmosphere. Even the distinction between day and night is lost. The flow of traffic goes on unceasingly and the noise never stops.

The funny thin about it all is that you pay dearly for the 'privilege' of living in a city. The demand for accommodation is so great that it is often impossible for ordinary people to buy a house of their own. Exorbitant rents must be paid for tiny flats which even country hens would disdain to live in. Accommodation apart, the cost of living is very high. Just about everything you buy is likely to be more expensive than it would be in the country. In addition to all this, city-dwellers live under constant threat. The crime rate in most cities is very high. House are burgled with alarming frequency. Cities breed crime and violence and are full of places you would be afraid to visit at night. If you think about it, they're not really fit to live in at all. Can anyone really doubt that the country is what man was born for and where he truly belongs？

People living in a large modern city have to ______.

A．tolerate some conditions rather than other ones

B．prefer a variety of their desired necessities

C．identify with being good consumers

D．be looking for the best in the future
