People, like most animals, are naturally lazy. So the ascent of mankind is something of a mystery. Humans who make their livings hunting and gathering in the traditional way do not have to put much effort into it. Farmers who rely on rain to water their crops work significantly harder, and lead unhealthier lives. But the real back-breaking is that carried out by farmers who use irrigation. Yet it was the invention of irrigation, at first sight so harmful to its practitioners that actually produced a sufficient surplus to feed the priests, scholars, artists and so on whose activities are collectively thought of as "civilization".
In the past 10,000 years, the world’s climate has become temporarily colder and drier on several occasions. The first of these, known as the Younger Dryas, after a tundra-loving plant that thrived during it, occurred at the same time as the beginning of agriculture in northern Mesopotamia. It is widely believe
A. alleviate farmers' workload.
B. increase agricultural production.
C. make planting much easier.
D. get rid of human laziness.

Most young people enjoy some form of physical activity. It may be walking, cycling or swimming, or in winter, skating or skiing; it may be a game of some kind: football, hockey, golf, or tennis; it may be mountaineering.
Those who have a passion for climbing high and difficult mountains are often looked upon with astonishment. Why are men and women willing to suffer cold and hardship, and to take risks on high mountains This astonishment is caused probably by the difference between mountaineering and other forms of activity to which men give their leisure.
Mountaineering is a sport and not a game. There are no man - made rules, as there are for such games as golf and football. There are, of course, rules of a different kind which it would be dangerous to ignore, but it is this freedom from man- made rules that makes mountaineering attractive to many people. Those who climb mountains are free to use their own methods.
If we compare mou
A. Mountaineering
B. Mountain Climbers
C. Mountaineering Is Different from Golf and Football
D. Mountaineering Is More Dangerous than Other Sports
Passage Three
If you are like most people, your intelligence varies from season to season. You are probably a lot sharper in the spring than you are at any other time of the year. A noted scientist, Ellsworth Huntington(1876-1947),concluded from other men’s work and his own among peoples in different climates that climate and temperature have a definite effect on our mental abilities.
He found that cool weather is much more favorable for creative thinking than is summer heat. This does not mean that all people are less intelligent in the summer than they are during the rest of the year. It does mean, however, that the mental abilities of large numbers of people tend to be lowest in the summer.
Spring appears to be the best period of the year for thinking. One reason may be that in the spring man’s mental abilities are affected by the same factors that bring about great changes in all nature.
Fall is the next-best season, then win
A. all nature, including man, is growing then
B. it lasts longer than the other seasons
C. it is not too warm and not too cold
D. both B and C
