[单项选择]Passage Three
The men who planned and constructed the first American railroads were men of great vision. They predicted that their “iron horses” would open vast expanses of land to farming and industry. They knew that towns would spring up along the new railroads. Yet few of these pioneers could have guessed that American railroads would establish the system of time used throughout most of the world today.
Until the 1880s, all time in the United States was sun time. Farmers set their clocks to noon when the sun appeared to be overhead. In towns, people set their clocks by a courthouse clock or factory whistles. One town’s time was often different from the time in a neighboring town.
As the new railroads expanded, large numbers of people began to travel. But the railroads were unable to print accurate timetables when most towns along their tracks have their clocks set differently. There was need for a change, and the railroads led in planning it.
In 1883, rai
A. Farmers set their clocks according to the factory whistles
B. The correct time was not too important before the 1800s
C. Only people who traveled on trains ever knew time
D. A standard system was set up by the pioneers

[不定项选择题]Among the most popular books being written today are those which are usually classified as science fiction. Hundreds of titles are published every year and are read by all kinds of people.
Furthermore, some of the most successful films in recent years have been based on science fiction stories.
It is often thought that science fiction is a fairly new development in literature, but it can be found in books written hundreds of years ago. These books were often concerned with the presentation of some form of ideal society, a theme which is still often found in modern stories.
Most of the classics of science fiction, however, have been written within the last hundred years. Books by writers such as Jules Verne and
H.
G. Wells, to mention just two well-known
authors, have been translated into many languages. Modern science fiction writers don't write about men from Mars or space adventure stories. They are more interested in predicting the results of technical developments on society and the human mind; or in imagining future world which are a reflection of the world which we live in now. Because of this their writing has obviously political undertones.
In an age where science fact frequently overtakes science fiction, the writers may find it difficult to keep ahead of scientific advances. Those who are sufficiently clear-sighted to see the way we are going, however, may provide a valuable lesson on how to deal with the problems which society will inevitably face as it tries to master its new technology.

B.prediction the results of technical developments on society
C.predicting the human mind

[听力原文] 11-15
Mr. and Mrs. Jones had no car of their own when they first came to the U. S. Therefore they went to work by bus every day. On one weekend, they wanted to go downtown by subway to go shopping. Then they walked to one building named "Subway". The signboard of "Subway" was very noticeable and they could see it when the bus passed it every day. At that time they did not know it was a "store", for they always believed it was a subway stop. When they arrived there they walked around the store for half an hour, but they still could not find the entrance to go down.
Finally through making an inquiry, they came to know that "Subway" is a famous store of sandwiches. "Sub" is a short form of "submarine sandwich", which is a long thin loaf of bread filled with salad and cold meat or cheese.
Since then, whenever they pass by the "Subway", they can’t help laughing.
What did the
