Now we are going to do some reading exercise. The passages we are going to read are GREAT INVENTIONS and THE HIGH COST OF LIVING. Let’s do them. Please remember you must finish doing each of them within 4 minutes and a half.
15. Great Inventions
Chinese translation
  There have been many great inventions, things that changed the way we live. The first great invention was one that is still very important today---- the wheel. This made it easer 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 1800's the world started to change. There was little unknown land left in the world. People didn’t have to explore much anymore. 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 become a big part of our life today.

 The first part of the 20th century saw more great inventions. The helicopter in 1909. Sound movies in 1926. The computer in 1928. And jet planes in l930. This was also a time when a new material was first made. Nylon came out in l935. It changed the kind of clothes people wear.

 The middle part of the 20th century brought new ways to help people get over diseases. They worked very well. They made people healthier and let them live long lives. By the 1960's 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 is known to man but the stars are not yet. 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.

 In 1969 man took his biggest step away from earth. Americans first walked on the moon. This is certainly just a beginning though. New inventions will someday allow us to do things we have never yet dreamed of.

16. The High Cost of Living
Chinese translation
  Many families in the United States have a large income now than ever before, but people are finding it difficult to make ends meet anyway. Almost everyone is wondering, "What happens to all my money? I never seem to have anything left to put away."

Why isn't a dollar worth as much as it used to be? One dollar is always worth the same amount, that is, 100 cents. But the value of a dollar is how much it can buy. The value of money depends on the cost of living. Economists say that the cost of living is the money that a family must pay for the necessities of life such as food, housing or rent, clothes, and medical expenses. For many years now, the cost of living has increased greatly, so the value of the dollar has decreased. When a dollar has a low value, you cannot buy as many things with it.

No one fully understands why the cost of living keeps increasing, but economists believe that workers and producers can make prices go up. As workers earn more money, they have more money to spend, so they demand more goods. If there is a great demand for certain goods, the prices of these goods go up. At the same time, if there's a shortage of goods, the prices also go up. For example, if everyone wants to buy more and more gas, the price of gas goes up. When companies withhold gas from buyers, they can also make the price of gas go up.

Families need to know what happens to their money. They need to make their income meet the cost of living, so many people plan a family budget. A budget is a list of monthly expenses. If your expenses add up to more than your income, you must find ways to save money. Maybe you're spending too much on entertainment. Or if you're spending too much on clothes, you may want to sew your own clothes. Budgeting helps you spend your money wisely as the cost of living increases.
