Investors wanted to sell their shares before the stock lost value. Over the next 5 days millions of shares flooded the market. Many investors lost all their money.During 1920s many Americans had invested in the stock market (股票市场). Many got rich.In 1928. Herbert Hoover was elected president. He said the future was bright with hope.People were being advised to buy stock before prices climbed even higher. Common sense was in short supply. Stock market rules let investors buy shares even if they did not have enough money. That is still true today but there are stronger controls.During the summer of 1929,some economists warned that there was no real value behind the high prices. President Hoover urged stock market officials to make trading safer and more honest. But he did not think the government should interfere in the market.When the drop in stock prices finally came,it was slow at first. It picked up speed (加速) as investors sold more and more shares. Several bankers bought stocks in an effort to prevent a crash. But the intense activity continued. October 29 is remembered as Black Tuesday. That day alone,stocks lost a tenth of their value.The crash (暴跌) caused a lot of people to lose their jobs,their farms and their homes. Many banks and businesses failed. The crash led to a worldwide depression (萧条) .36. The reason for the Great Crash is .A. that millions of shares flooded the marketB. Herbert Hoover was elected presidentC. the future was bright with hopeD. people kept buying stock before prices climbed even higher37. The government was responsible for the Great Crash of 1929 because .A. it urged stock market officials to make trading safer and more honestB. it did not interfere in the marketC. investors sold shares even if they did not have enough moneyD. fear seized the New York Stock Exchange38.

The passage mainly concentrates on .A. the context of the Great Crash of 1929B. the coming and going of the Great Crash of 1929C. the prosperous period of the AmericaD. the story of a stock marketPassage TwoThere are thousands of different languages in the world. Everyone seems to think that his native (本国) language is the most important one,as it is their first language. For many people it is even their only language all their lives. But English is the world's most widely used language.As a native language,English is spoken by nearly three hundred million people:in the U. S. ,England,Australia and some other countries.For people in India and many other countries,English is often necessary for business,education,information and other activities. So English is the second language there.As a foreign language,no other language is more widely studied or used than English. We use it to listen to the radio,to read books or to travel.

The sound came from the waste basket. Walt looked at it and saw a family of mice eating pieces of bread in it. For many nights,they played there. And Walt began to like them.Walt liked one little mouse better than any of the others. This little animal gave him some new ideas for his drawing. He began to draw it. But in the picture,it did not look like a mouse,but more like a funny man. He showed it to his wife and she liked it very much,too.Walt named this little m ouse “Mickey Mouse”. He hoped his Mickey Mouse would be different from the other pictures of his. He wanted to make Mickey talk. He put his fingers on his nose and made a strange sound. Then he recorded the voice this way. Later he sold his sound pictures to a cinema. When the film was shown,many people went to see it.
