[单项选择]THE PRODUCTION OF COFFEE

1 All great coffee comes from the same tree, Coffea arabica. The distinguishing taste of coffee is a product of the climate, air, and soil in which it is grown. The perfect climate for coffee production exists between the latitudes of 25 degrees north and 25 degrees south of the equator. The coffee plant is particular about temperature, and changes of more than 20 degrees in twenty-four hours, or temperatures of over 70 degrees Fahrenheit, tend to have harmful effects on production. In general, coffee trees are comfortable where people are. If people feel too cold or hot, especially during flowering and fruit development, the trees are not likely to do well.
2 Altitude is an important factor, and most coffee-producing countries grade their coffees according to the altitude at which they were grown. The best-tasting coffees are grown at between five and eight thousand feet in elevation, in the thin air and
A. A mountainous region close to the equator
B. A region with a large coffee-drinking population
C. A coastal region with a moderate amount of rainfall
D. A region with an average temperature of 70 degrees F

All U. S. nuclear weapons production facilities are presently closed down, and if the various agreements are adhered to, those facilities will never be required except for one critical capability. All modern nuclear weapons use uranium (铀), plutonium (钚), and tritium (氚). Uranium and plutonium have very long half-lives, and there is large surplus of these materials.
Tritium, however, has a relatively short half life of about 12.6 years, so about 5 percent of the amount on hand must be replaced each year to maintain the current inventory. (46) Because of the large retirement of nuclear weapons by the United States in compliance with early agreements and national policy, tritium from retired weapons has been used to make up that lost through natural decay. (47) However, in about 10 to 15 years, depending on future negotiations, the United States will need a guaranteed supply of tritium to maintain its stockpile at whatever level is agreed on.

All truly great thoughts are conceived while walking, observed Nietzsche, though I’ve always been a bit suspicious of the eagerness with which writers and artists celebrate the inspirational power of taking a stroll. Yet it seems to work. "methinks(我想) the moment my legs begin to move, my thoughts begin to flow," was how Henry Thoreau described an experience many of us have had, be it tackling challenging work or worrying over problems.
If we still don’t know why walking inspires clarity and creativity, it’s because there are too many possible explanations, not too few. An evolutionary psychologist might say we’re designed to thrive outside, not at a desk; a scholar of the psychological phenomenon of "priming" might point to studies suggesting that high ceilings-and also, perhaps, the sky—prompt unrestrained thinking. A study in the European Journal
A. He wants to challenge things in an extreme way.
B. He wants to make violation of writer’s solitude.
C. He wants to test his theory of "competing concentration".
D. He wants to be forced by something to concentrate.
