A house is the most expensive thing most people will ever buy. Very few people have enough money of their own to buy a home, so they have to borrow money from a bank. Borrowing money from a bank to buy a house is called “take a mortgage（抵押）”. The bank usually lends money or gives a mortgage for twenty-five years. Houses are so expensive that many people nowadays have to borrow as much as $50 000. In other words they will have a $50 000 mortgage.
How can you get a mortgage? When you find a house you like, you go to a bank. The bank will research you financial（金融的）history and decide if they think you are a good risk. They will want to know what kind of job you have, what kind of salary you make, and how long you have had the job. They will also want to know how much money you have. In addition, the banks will require a down payment. Depending on which state you live in, the bank may require as much as 30% of the price of the house as a down payment, The bank will then lend you the rest of the money to buy the house. Many people are never able to buy a house because they cannot save enough money for the down payment.

单项选择题After working long hours on her feet everyday in the operating room, Taryn Rose knew a lot about foot pain. But unlike most of her colleagues（同事）, she turned her pain into money. Today she is the boss of Taryn Rose International, a $528 million company that makes nice and comfortable shoes.
At the beginning, Rose realized the only thing that could stop her was fear of failure. “I could hear my friends and family saying, ‘Why did you leave a good job?’ If I failed, would I be okay facing them? And I thought, ‘So what? I can go back for further study in medicine.’ I started to accept that it would be okay to say, ‘I failed, but I tried.’ Once I was comfortable with that thought, the fear came to an end. I realized I feared regret more than failure. And after you turn to the path you choose, there is nothing acceptable but Success. ”
Now, Rose has no regrets about leaving medicine. “What I’m doing is not all that different from what I was doing as a doctor. The goal is the same to relieve pain. A former professor told me, ‘You’re helping hundreds of thousands of women with your shoes. As a doctor, you would have helped only the few who went to your office. You’re having a much greater effect.’”
Looking back, Rose admits she caught a couple of lucky breaks. “To me, luck is about being prepared for those opportunities（机会）that come knocking. You have to have an open mind, the right skills and all your senses working to see what opportunities present themselves. Luck can open the door, but you still have to walk through it.”
