Passage3        Questions 11 to 15 are based on the following passage.        Many of the most damaging and life threatening types of weather, such as torrential rains and severe thunderstorms, begin quickly, strike suddenly, and disappear rapidly, destroying small regions while leaving neighboring areas untouched. (79) Conventional(普通) computer models of the atmosphere have limited value in predicting short-lived local storms because the available weather data are generally not detailed enough to allow computers to see clearly the small atmospheric changes that come before these storms.In most nations, for example, weather-balloon observations are taken just once ever3r twelve hours at location 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 impracticable. 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 beyond overcoming.Fortunately, scientific and technological advance have overcome most of these problems. Radar systems, automated weather instruments, and satellites are all capable of making detailed, nearly continuous observations over large regions at a relatively low cost. Communication satellites can transmit data around the world cheaply and immediately, and modern computers can quickly compile and analyze this large volume of weather information. (80) Meteorologists(气象学家)and computer scientists now work together to design computer programs and video equipment capable of transforming r.aw 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.14 Things have been changed by the following EXCEPT______.
A

the use of radar systems and automated instruments

B

the use of communication satellites and modern computers

C

the joint work of meteorologists and computer scientists

D

weather information volume is large enough to compile and analyze

    Practice 1Directions: In this part of the test, you will answer three questions based on the information provided. You will have 30 seconds to read the information before the questions begin. For each question, begin responding immediately after you hear a beep. No additional preparation time is provided. You will have 15 seconds to respond to Questions 1 and 2 and 30 seconds to respond to Question 3.Practice 1  Question 1: How much are tickets?  Question 2: I heard Time Against Time was coming out. Is it playing there yet?  Question 3: I might not be able to go to the theater until 7:30. Which movies are playing at around that time?

    正确答案: 1: It’s eight dollars and ninety-five cents for adult tickets. And for kids, it’s five dollars and ninety-five cents.
    或:An adult ticket is eight ninety-five and a ticket for a child is five ninety-five.
    解 析:解答本类题型最重要的是从屏幕显示的文件或日程表中快速找到问题对应的部分从而作答。本题问How much…询问的是价格,所以在日程表下面找到票价作答。记住dollar和cent后面要加复数-s,dollar和cent之间要用and连接。
    2:Yes, it is playing in the theater, and it plays at several different times.
    或:Yes, it is being shown at the theater at present.
    解 析:本部分的问题通过录音形式播放,不会显示在屏幕上,所以更要集中注意力听好。这道题用不含疑问词的疑问句提问,所以首先要回答Yes或No,再做进一步必要的说明。虽然可以直接使用提问中的is playing表示“上映”,但此处使用is being shown更体现多样的表达能力。
    3:Well, you have many choices. At seven forty, Geneva is playing and five minutes later, Whispers in the Silence is playing. And a little bit later, at ten to eight, Rabbit Stew is going to start.

    Passage3      Questions 11 to 15 are based on the following passage.     When we accept the evidence of our unaided eyes and describe the Sun as a yellow star,we have summed up the most important single fact about it-at this moment in time.It appears probable, however, that sunlight will be the color we know for only a negligibly(微不足道的)small part of the  Sun's history.       Stars, like individuals, age and change.As we look out into space,we see around us stars at all stages of evolution.There are faint blooded dwarfs so cool that their surface temperature is a mere 4,000 degrees Fahrenheit; there are scaring ghosts blazing at 100,000 degrees Fahrenheit and almost too hot to be seen, for the great part of their radiation is in the invisible ultraviolet range.Obviously, thedaylight produced by any star depends on its temperature, today (and for ages to come) our Sun is at about 10,000 degrees Fahrenheit, and this means that most of the Sun's light is concentrated in the yellow band of the spectrum, falling slowly in intensity toward both the longer and shorter light waves.          That yellowhump will shift as the Sun evolves,and the light of the day will change accordingly.(80) It is natural to assume that as the Sun grows older, and uses up its hydrogen fuel-which it is now doing at the spanking rate of half a billion tons a second-it will become steadily colder and redder.14 According to the passage, as the Sun continues to age, what color is it likely to become?

    ◆Topic 11:On Bicycle Theft  Questions for reference:  1) Is bicycle theft commonly seen on campus?  2) What are the causes for the theft?  3) What can universities you to stop such phenomenon?

    正确答案: 【参考答案】
    Bicycle theft is very common on campus, which is immoral and illegal. And it is damaging to the academic image of the colleges and universities.
    There are several reasons for this. First, the security system of the school should be partially responsible for the losses. Besides, more than too often, students’ carelessness leaves opportunities for the thieves. Sometimes when they have to leave their bicycles for 10 minutes, they will not take the trouble to lock them. The last point that is also worth mentioning is that there is a lack of moral education in most schools.
    Considering these situations, the school and the students should work together to fight against this phenomenon On the one hand, the school security system should be perfected. On the other hand, students should learn to he more allergic. Above all, moral education must be added and emphasized.
