听力原文：Millions of years ago, whales lived on land and walked on four legs. Today, whale

听力原文： Millions of years ago, whales lived on land and walked on four legs. Today, whales still have small bones that are the remains of their hind legs, but these bones can only be seen on the inside of the whale. No one knows why whales left the land to live in the water.

However, scientists can imagine that when the whales changed their environment, their bodies underwent a change—taking on a more fish-like appearance. This new form. offered less resistance to the water, enabling the whales to swim faster.

Despite their fish like form, whales are not fish. A whale will drown, just as a man will, if it stays under water too long. When a whale is under water, it closes its nostrils tightly and holds its breath. The air in its lungs becomes very hot and full of water vapor. When the whale rises to the surface and exhales, its hot breath produces a column of water vapor that rises high in the air. A man produces the same effect when he exhales warm air on a cold morning.

Whales are classified as mammals because they bear their young, rather than laying eggs, and because the mother whales give the babies milk. Like other mammals, whales have warm blood. Their blood stays at the same temperature, even when they move from hot to cold water. They keep warm in cold water because they have a thick layer of fat just under their skins. This fat is called blubber, and it is thicker on whales that spend their lives in cold water. Almost all land mammals, except man, have hair on their bodies to keep them warm, but whales, which have very few hairs, are kept warm by their fat.

How does a whale keep itself warm？

A．By its thick layer of fat under its skin.

B．By moving frequently in the water.

C．By adjusting its blood temperature.

D．By taking in hot air.

听力原文： There have been many great inventions, things that change the way we live. The first great invention was one that is still very important today--the wheel. This made it easier to carry heavy things and to travel long distances.

For hundreds of years after that there were few inventions that had as much effect as the wheel. Then in the early 1800s the world started to change. There was little unknown land left in the world. People did not have to explore much any more. They began to work instead to make life better.

In the second half of the 19th century many great inventions were made. Among them were the camera, the electric light and the radio. These all became a big part of our life today.

The middle part of the 20th century brought new ways to help get over diseases. They worked very well. They made people healthier and let them live longer lives, By the 1960s most people could expect to live to be at least 60.

By this time most people had a very good life. Of course new inventions continued to be made. But man now had a desire to explore again. The world was known to man, but the stars were not. Man began looking for ways to go into space. Russia made the first step. Then the United States took a step. Since then other countries, including China and Japan, have made their steps into space.

(23)

A．In the second half of the 19th century.

B．In the 1960s.

C．In the first half of the 20th century.

D．In the early 1800s.

听力原文：Richard Arkwright was born on December 23, 1732, in Preston, Lancashire, to a poo

听力原文： Richard Arkwright was born on December 23, 1732, in Preston, Lancashire, to a poor family. He was taught to read and write by his cousin, and later became apprenticed to a barber. Arkwright was an ambitious man, however, and soon struck out on his own. He started a wig-making business, in the course of which he travelled widely in Great Britain, collecting hair for his wigs. On his travels he met John Kay, who had invented a new spinning machine for the burgeoning textile industry. Arkwright was so impressed by Kay's machine that he hired the man to build it for him. The new Spinning Frame. produced a thread far stronger than any- thing available at that time, and it was able to spin 128 threads at one time. Equally important, from Arkwright's point of view, the machine did not require a skilled operator to run it. Unfortunately, the size of the Spinning Frame. made hand-operation impossible. Arkwright tried using horsepower, but finally settled on using a waterwheel to power the machine. In 1771 he and his business partners Jedediah Strutt and Samuel Need established a factory on the banks of the River Derwent in Cromford, Derbyshire. Arkwright was the first to successfully create a system of mass-production. His factories and his methods were widely copied throughout Eng- land and around the world.

What was Richard Arkwright well known as？

A．A barber.

B．The founder of mass-production.

C．A traveller.

D．A skilled operator.

听力原文： One day in 1848, a carpenter named Marshall, who worked in a sawmill on the American River in California, made a surprising discovery. He noticed something bright and yellow, bent down to pick it up and took it to his friend, a Mr. Sutter. This was the beginning of the Californian Gold Rush. Sutter was a Swiss who had come to America to try to make a lot of money. The Governor of California had given him permission to make a home in the Sacramento Valley and his determination and energy had made him rich. He had built the mill together with Marshall in order to make use of the rich natural materials of his land.

Sutter realized the importance of the discovery and decided to ask the Governor for the right to the gold. So he sent a man named Bennet to San Francisco to see the Governor. He warned Bennet not to tell anyone because he was afraid that people would come before his right was recognized. Bennet could not keep the secret but people did not believe him at first. Then a newspaperman went to Sutter's mill to make a report. When he came back he ran through the streets shouting, "Gold! Gold!" Within a month almost the entire population had gone to look for the gold.

Then news spread across America to Europe and thousands of people joined in the search. Those who went by ship had to sail round Cape Horn but some preferred to go across America by land, and freight cars were used for travelers. Even then there were some who were prepared to cross the terrible desert of Death Valley.

The Gold Rush proved to be fatal to Sutter himself. For years he tried to get rid of those new-comers so that his family might enjoy the wealth of his land, but his business failed. The new-comers did a great deal of harm, and even killed one of his sons, and at the end of his life he was a poor man who often stopped people in the street to tell them that gold was worse than anything else.

Who was the first to find the gold in California？

A．Sutter.

B．Marshall.

C．Bennet.

D．A newspaperman.

听力原文： This guy goes to a bar that's on the tenth floor of a hotel. He sits down and has a couple of drinks, then stands up, announces loudly that he has had enough, and goes over and jumps out the window. Now, there are two men who are sitting at a window table, and having that natural human curiosity about the strange situation, watch as this man put himself to certain death. However, just as he is about to hit the ground, he rights himself, pulls his feet underneath himself, and lands gracefully. He then turns and comes back into the building. Naturally, the two men are amazed. The guy comes back into the bar, orders a few drinks, then repeats the process. The two men at the window seat are astonished! When the guy returns and repeats the procedure AGAIN, the two men stop him before he jumps and ask him how on earth he does that. He replies "It's simple, really. There'& an air vent down by the ground, and if you catch the updraft, you can right yourself and land on the ground with no problems. ' Then he proceeded to jump out the window again. Well, these two men decided that they just HAD to try this, so they jumped out the window, and SPLAT! -- made a mess hitting all over the ground. Meanwhile, the first guy has made it back up to the bar. When he sits down to order his drinks, the bartender says "You can be a real superman- when you're drunk!"

A．fourth.

B．fifth.

C．tenth.
