Hopewell sells a line of goods under a six－month warranty.Any defect arising during t

Hopewell sells a line of goods under a six-month warranty.Any defect arising during that period is repaired free of charge.Hopewell has calculated that if all the goods sold in the last six months of the year required repairs the cost would be $2 million.If all of these goods had more serious faults and had to be replaced the cost would be $6 million.

The normal pattern is that 80% of goods sold will be fault-free, 15% will require repairs and 5% will have to be replaced.

What is the amount of the provision required().

A、$2 million

B、$1.6 million

C、$6 million

D、$0.6 million

Many of the most damaging and life threatening types of weather torrential rains, seve

re thunderstorms, and tornadoes begin quickly, strike suddenly, and disappear rapidly, destroying small regions while leaving neighboring areas untouched.Such event as a tornado struck the northeastern section of Edmonton, Alberta, in July 1987.Total damages from the tornado exceeded $250 million, the highest ever for any Canadian storm.

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 ____________.

A.added up toB.were more than

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
