You arrive at the mall anxious to buy your favorite CD or the coolest computer game. Nothing will stop you, not even the price — even if you don't have enough money, Mom or Dad will use a credit card(信用卡) to pay. But wait! Is using a credit card really that simple? There are some things you should know about using credit cards before you go shopping.

1.Credit card companies lend you money, which you are expected to pay back. They don’t lend you money just to be nice, however. In fact, they make billions of dollars this way.

You spend 45 dollars buying a pair of jeans on a credit card, then about a month later, the credit company sends you a bill for 45 dollars.2.But what if you can’t pay the whole bill? Usually, you are allowed to pay part of it. Let’s say you pay $10 the first month. Now the credit card company begins to get money from you. They charge extra money, called interest(利息), on whatever part of the money you didn't pay.

Now the $35 you still have on your bill begins to grow. Even if you don’t buy anything more, by the time you get your bill the following month, you will have more than $35 to need paying back. And every day, interest keeps adding up.3.

But the good news is that a credit card is convenient. 4.Besides, the credit card companies also offer extra services. For example, if something you bought online with your card stops working in a short time, the company may give your money back.

5.They spend more money than they can afford to pay back. Knowing how to use credit wisely will be necessary and help you to be a smart shopper.

 

A. It is sometimes the only way to pay when you shop over the Internet.

B. You'd better borrow money from friends instead of using a credit card.

C. Using a credit card is a way of borrowing money to buy things.

D. Some people get themselves in trouble with credit cards.

E. If you pay the whole 45 dollars back right away, it won't cost you anything.

F. So actually those jeans will end up costing you more than $ 45.

G. I always believe money is not everything.
