阅读理解。 It's only $79.99! How many times have you heard those words on TV or read them in a newspaper ad? The word "'only" is supposed to make you think that this is a great price for the product. But think about this. How long does it take you to earn $79.99? What do you have to do to get that money? The little thing that's only $79.99 is worth (价值) almost 12 hours of your work! And if you are less than this, how long will it take to earn that much money? So as you stand in a store, telling yourself that you have to buy something, think about how long you must work to earn the money to pay for it. Is that $85 T-shirt really worth the time to earn $85? You could probably find a similar shirt at another store for under $35, right? Even if your parents are still buying your clothes, someone has to work for the money. If you spend money on one thing, you don't have money to spend on anything else.So if you spend $85 on those jeans, you cannot put it in the bank, and you cannot go snowboarding(单板滑雪)or to the movies with friends because you don't have the money to go. 1.
