Conventional computer models of the atmosphere have limited value in predicting short lived local storms like the Edmonton tornado, because the available weather data are generally not detailed enough to allow computers to study carefully the subtle atmospheric changes that come before these storms.In most nations, for example, weather – balloon observations are taken just once every twelve hours at locations typically separated by hundreds of miles.With such limited data, conventional forecasting models do a much better job predicting general weather conditions over large regions than they do forecasting specific local events.
Until recently, the observation intensive approach needed for accurate, very short – range forecasts, or “Nowcasts,” was not feasible.The cost of equipping and operating many thousands of conventional weather stations was extremely high, and the difficulties involved in rapidly collecting and processing the raw weather data from such a network were hard to overcome.Fortunately, scientific and technological advances have overcome most of these problems.Radar systems, automated weather instruments, and satellites are all capable of making detailed, nearly continuous observation over large regions at a relatively low cost.Communications satellites can transmit data around the world cheaply and instantaneously, and modern computers can quickly compile and analyze this large volume of weather information.Meteorologists and computer scientists now work together to design computer programs and video equipment capable of transforming raw weather data into words, symbols, and vivid graphic displays that forecasters can interpret easily and quickly.As meteorologists have begun using these new technologies in weather forecasting offices, Nowcasting is becoming a reality.
11.The word “exceeded” in paragraph I most probably means ____________.

C.were about D.were less than
12.Conventional computer models of the atmosphere fails to predict such a short – lived tornado because ______________.
A.the computer is not used to forecast specific local events
B.the computers are not advanced enough to predict it
C.the weather data people collect are often wrong
D.weather conditions in some small regions are not available
13.According to the passage, the word “Nowcast” (paragraph 3) means _______________.
A.a way of collecting raw weather data
B.a forecast which can predict the weather conditions in the small area in an accurate way
C.a network to collect instant weather data
D.a more advanced system of weather observation
14.According to the passage, ___________ is the key factor to making “Nowcasts” a reality.
A.scientific and technological advances such as radar, or satellites
B.computer scientist
C.meteorologists
D.advanced computer programs
15.According to the author, the passage mainly deals with ________________.
A.a tornado in Edmonton, Alberta
B.what’s a “Nowcast”
C.the disadvantage of conventional computer models of the weather forecast
D.a breakthrough in weather forecast
For Americans, time is a "resource" that, like water or coal, can be used well or poorly."Time is money," they say."You only get so much time in this life; you'd best use it wisely." The future will not be better than the past or the present unless people use their time for constructive, future-oriented activities.Thus, Americans admire a “well-organized” person, one who has a written list of things to do and a schedule for doing them.The ideal person is punctual and treasures other people's time.
The American attitude towards time is not necessarily shared by others, especially non-Europeans.They are more likely to consider time as something that is simply there around them, not something they can "use".One of the more difficult things many foreign businessmen and students must adjust to in the States is the notion that time must be saved whenever possible and used wisely every day.
In their efforts to use their time wisely, Americans are sometimes seen by foreign visitors as automatons, unhuman creatures who are so tied to their clocks and their schedules that they cannot participate in or enjoy the human interactions that are the truly important things in life."They are like little machines running around," one foreign visitor said.
The emphasis Americans place on efficiency is closely related to their concepts of the future, change and time.To do something efficiently is to do it in the way that is quickest and requires the smallest investment of resources.American businesses sometimes hire "efficiency experts" to review their operations and suggest ways in which they could accomplish more than they are currently accomplishing with the resources they are investing.Popular periodicals carry suggestions for more efficient ways to clean house, raise children, tend the yard, and so on.
In this context the "fast-food industry" can be seen as a clear example of an American cultural product.McDonald's, Kentucky Fried Chicken, Pizza Hut, and other fast-food establishments prosper in a country where many people want to minimize the amount of time they spend preparing and eating meals.The millions of Americans who take their meals at fast-food restaurants cannot have much interest in lingering over their food while conversing with friends, as millions of Europeans do.As McDonald's restaurants have spread around the world, they have been viewed as symbols of American society and culture, bringing not just hamburgers but an emphasis on speed, efficiency, and shiny cleanliness.The typical American food, some observers argue, is fast food.
