People often think that having a million dollars would make all their dreams come true. There are TV game shows that give contestants the chance to become millionaires. When asked the question "What would you do with a million dollars?", most people tend to give similar answers: “Quit my job.”, "Buy my dream house," or “Go traveling.” Twenty years ago, it was possible to realize these dreams. However, things are not so easy today.

In many developed countries, the cost of living is higher than ever. Over the last twenty years, for example, housing prices in many of the world's cities have soared. In the U. S., luxury homes in the state of Arizona sold for about $ 800, 000 in 1995. These same homes now cost more than $ 1.5 million. Now, because more people live in the area, the cost of property has risen.

Apartments in many city centers are also more expensive now than in the past. Today, people want to be closer to their workplace, and many are now moving back into the city center. As a result, living in or near this area costs more than ever. Apartments in London's Mayfair district or in Manhattan in New York City often sell for over a million dollars.

Inflation is another important reason for the rise in the cost of living. Over the last 150 years, as prices have gone up, the value of money has gone down, so we now need more money to buy things. In 1850, for example, $50,000 had as much buying power as $1 million dollars does today. Of course, people now earn more money than they did 150 years ago, but they also spend more on necessities such as food, medicine, and housing.

In order to live well after you stop working, you should begin saving for retirement early. Experts suggest that after you retire, you will need 75 percent to 80 percent of your salary to live on every month. This calculation assumes that you have no mortgage on a house to continue paying, or any other major expenses.

Due to increased demand for housing, higher inflation, and longer life expectancy, a million may not be enough to live on. To be able to retire early, travel the world, and build your dream home, you may have to appear on that game show and win more than once!

46. What is the main cause of high housing price?

A. People generally make more money today.

B. There are more luxury homes than apartments.

D. things that one must pay for regularly

48. If you make $ 4,000 per month, you will need _______ per month after you retire.

A. $2,250~$2,400 B. $ 3,000~$ 3,200

C. $3,500~$3,750 D. $2,550~ $ 2,700

49. What does the underlined sentence mean in the last paragraph?

A. You will be so lucky that you can win another million dollars.

B. Don't expect too much for just a million dollars that cannot change your life completely.

C. A million dollars is too little to travel around the world.
