听力原文： For more than two hundred years people have been using trains. There are trains to carry people, trains to carry animals. There are fast trains, slow trains, trains that go under the ground, trains that go through mountains. In busy cities, trains have been put under the ground. The subway trains run on tracks through huge tunnels under the noise and traffic of the city. The monorail is another kind of train used in busy places. The train hangs from a rail high above the streets and it carries people quickly in and out of the city. Railroad tunnels which are miles long have been built through mountains. Do you think these tunnels are ready to build？ They are not. Workers spend many years on the job. Is it possible for a train to travel over water？ Yes, it is. Great bridges have been built just for trains. And railroad tunnels have been built under the water. Some trains travel great distances. You can travel for 2,461 miles on Australia's trains which go across the continent or you can ride 6,000 miles across Russia. Today's trains have nice little bedrooms and dining rooms for people who travel long distances. Years ago trains were used to carry important people. These trains had beautiful bedrooms, bathrooms, dining roans, and sitting rooms. They were like Hale palaces really fit for a king. You have probably seen freight trains. There are many kinds.

听力原文： It was not until one hundred and fifty years ago that scientists learned about the existence of dinosaurs. Thanks to an English doctor and his wife, the door was opened to this zoological study. Reasoning that these animals' tremendous size must have made them terrible creatures, scientists combined two Greek words, deimos, meaning terrible, and sauros, meaning lizards, to form. the word dinosaur.
After many years of study, they determined that these beasts roamed the earth for millions of years, and ceased to exist some sixty million years ago.
Unbelievable as it may seem, not all dinosaurs were carnivorous, that is, meat eating. Many were herbivorous, or vegetarians.
By reassembling the bones found at digging sites, scientists have been able to reconstruct the skeletons and learn great deal about the dinosaur's living conditions. They have learned that dinosaurs inhabited not only the land, but also the water and sky.

A．Beasts.
B．Herbivorous.

His instruments could reproduce tones as rich as those produced by the human voice. During his career he made over eleven hundred violins by hand. Those still in existence have become treasured possessions.
Unfortunately, the secret of the Stradivarius violin died with its maker. During his lifetime Stradivarius kept his notes safely hidden. Even his two sons, who helped him in his workshop, did not know all the steps involved in each violin's construction.
Through the years, many experts have offered possible explanations for the unique tone of a "Strad". Some say it is the instrument's shape and the harmony of its parts. Others suggest that the secret lies in the special properties of the wood that no longer exist. The most widely accepted supposition is the paint that the old master used to coat his instruments. Still, no violin maker has been able to fully reproduce the tone of Stradivarius's violins.

A．How to Make Violins.
B．Stradivarius's Secret.
C．Expensive Violins.
D．Italian Violin Makers.

听力原文： A computer is a machine designed to perform. work mathematically and to store and select information that has been fed into it. It is run by either mechanical or electronic means. These machines can do a great deal of complicated work in a very short time. A large computer, for example, can add or subtract nine thousand times a second, multiply a thousand times a second, or divide five hundred times a second. Its percentage of error is about one in a billion digits. It has been estimated that human beings making calculations average about one mistake per two hundred digits.
The heart of an electronic computer lies in its vacuum tubes, or transistors. Its electronic circuits work a thousand times faster than the nerve cells in the human brain. A problem that might take a human being two years to solve can be solved by a computer in one minute, but in order to work properly, a computer must be given instructions--it must be programmed.
Computers can be designed for many specialized purposes--they can be used to prepare payrolls, guide airplane flights, direct traffic, even to play chess. Computers play an essential role in modern automation in many plants and factories throughout the world.
