Beyond two or three days, the world’s best weather forecasts are doubtful, and beyond six or seven they are worthless.
The Butterfly Effect is the reason. For small pieces of weather―to a global forecaster, small can mean thunderstorms and blizzards (暴风雪)―any prediction becomes worse rapidly. Errors and uncertainties increase, from dust devils and storms up to continent-size eddies (旋涡) that only satellites can see.
The modern weather models work with net-like points sixty miles apart, and even so, some starting data have to be guessed, since ground stations and satellites cannot see everywhere. But suppose the earth could be covered with sensors placed one foot apart, rising at one-foot intervals all the way to the top of the atmosphere. Suppose every sensor gives perfectly accurate readings of temperature, pressure, humidity (湿度), and any other data a weatherman would want. Exactly at noon a powerful computer takes all the data and calculates what will happen at each point at 12.01, then 12.02, then 12.03… the computer will still be unable to predict whether Princeton will have sun or rain one month away. At noon the spaces between the sensors will hide fluctuations (波动) that the computer will not know about. By 12.01, those fluctuations will already have created small errors one foot away. Soon the errors will have added to the ten-foot scale, and so on up to the size of the globe.
72．A weather forecast ______ in the world.
A．is reliable within one or two days
B．is doubtful beyond 24 hours
C．becomes useless beyond two or three days
D．is still worthwhile in seven days
73．Usually there is a weather sub-station ______.
A．in every city B．every 60 miles
C．between two cities D．every one foot
74．Which of the following statements is true?
A．People have not placed sensors one foot apart in the atmosphere.
B．Scientists have already put sensors one foot apart in the world.
C．Every sensor gives perfectly accurate data a weatherman wants.

B．they are hidden by the spaces between the sensors
C．they are too far away

Forget Twitter and Facebook, Google and the Kindle. Television is still the most influential medium around. Indeed ,for many of the poorest regions of the world, it remains the next big thing——finally becomes globally available. And that is a good thing, because the TV revolution is changing lives for the better.
Across the developing world, around 45% of families had a TV in 1995; by 2005 the number had climbed above 60%. That is some way behind the U.S. , where are more TVs than people, and where people now easily get access to the Internet. Five million more families in sub-Saharan Africa will get a TV over the next five years. In 2005 , after the fall of the Taliban（塔利班）,which had outlawed TV, 1 in 5 Afghans had one. The global total is another 150 million by 2013——pushing the numbers to well beyond two thirds of families.
Television’s most powerful effect will be on the lives of women. In India, researchers Robert Jensen and Emily Oster found that when TVs reached villages, women were more likely to go to the market without their husbands’ approval and less likely to want a boy rather than a girl. They were more likely to make decisions over child health care. TV is also a powerful medium for adult education. In the Indian state of Gujarat, Chitrageet is a popular show that plays Bollywood songs with words in Gujarati on the screen. Within six months, viewers had made a small but significant improvement in their reading skills.
