SECTION B PASSAGES
Directions: In this section, you will hear several passages. Listen to the passages carefully and then answer the questions that follow.
听力原文: On 17th of September 1988, teams representing the National Olympic Committee from countries around the world will march into a stadium in Seoul, capital of South Korea. A runner carrying a burning torch which symbolizes the link with the Olympic games in ancient Greece will mount the steps, light the Olympic flame which will burn throughout the games, and the Games of the twenty-fourth Olympic will begin.
The Olympic idea means friendship and cooperation among the youth of the world. The Olympic Movement proves that real peace can be achieved through sport. Probably the best-known symbol of the Olympic Movement is the five linked rings, which represent the five continents of the world. The Olympic flag itself is white and the rings are in five colors, blue, yellow, black, green and red. Any national flag contains at least one of these five colors.
The original Games began in ancient Greece in 776 B. C. These games were part of a festival held every four years in honour of the god, Zeus, at a place called Olympia. The festival included contests that tested the skills of soldiers. Some Olympic sports such as boxing and wrestling and many of the athletic events have a long history. The modern games, revived in AD 1896, owe a lot to one man, Baron Pierre de Coubertin. He suggested that the Olympic Games which were discontinued in AD 393, should be restored and he helped establish the structure of the modern Olympic Movement.
According to the passage, what does the burning torch symbolize?
A.The link with the games in ancient Greece.
B.The link with the god, Zeus.
C.The link with Baron Pierre de Goubertin.
D.The link with the five colors.

听力原文: Over 2,000 years ago, Rome was the center of a large empire. The Romans needed a way to move their large armies quickly so they could protect their huge country. They needed trade routes. So they joined all the parts of their empire by a network of roads.
Beginning in 300 BC, the Romans built roads in Europe, Asia, and North Africa. By AD 200, they had built 50,000 miles of almost straight highways.
To build their roads, the Romans sometimes had to dig tunnels through mountains. They did mot have explosives to cut through the rock. They heated the rock with fire and then threw cold water over it. When the rock cracked, they dug it out with hand tools.
Roman soldiers and slaves built the roads without powerful machinery. They had only simple tools. Yet the roads were so well built that they were used for hundreds of years.
Why did the Romans build so many roads?
A.They wanted Rome to become the center of the world.
B.They wanted to pave important roads with large, flat stones.
C.They needed to keep their soldiers busy by making them build roads.
D.They needed the roads to move large armies and trade goods.

Section B
Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.
A weather map is an important tool for geographers. A succession of three or four maps presents a continuous picture of weather changes. Weather forecasters are able to determine the speed of air masses and fronts; to deter mine whether an individual pressure area is deepening or becoming shallow and whether a front is increasing or decreasing in intensity. They are also able to determine whether an air mass is retaining its original characteristics or taking on those of the surface over which it is moving. Thus, a most significant function of the map is to reveal a synoptic picture of conditions in the atmosphere at a given time.
All students of geography should be able to interpret a weather. map accurately. Weather maps contain an enormous amount of information about weather conditions existing at the time of observation over a large geographical area. They reveal in a few minutes what otherwise would take hours to describe. The United States Weather Bureau issues information about approaching storms, floods, frosts, droughts, and all climatic conditions in general. Twice a 'month it issues a 30-day "outlook" which is a rough guide to weather conditions likely to occur over broad areas of the United States. These 30-day outlooks are based upon an analysis of the upper air levels which often set the stage for the development of air masses, fronts, and storms.
Considerable effort is being exerted today to achieve more accurate weather predictions. With the use of electronic instruments and earth satellites, enormous gains have taken place recently in identifying and tracking storms over regions which have but few meteorological stations. Extensive experiments are also in progress for weather modification studies. But the limitations of modification have prevented meteorological results except in the seeding of super-cooled, upslope mountainous winds which have produced ad ditional orographic (山岳形态的) precipitation (山岳雨) on the windward side of mountain ranges. Nevertheless, they have provided a clearer under standing of the fundamentals of weather elements.
All the following characteristics of weather maps are mentioned in this passage EXCEPT ______.
A.barometric pressure
B.fronts
C.thermal changes
D.wind speed
