You s houldn' t worry about that as you【C6】________(probable) get lots of advantages out of your mistakes.

Think again. Leasing can end up being just as expensive as buying. Most people think about leasing because they believe it will cost them less money. They're right-it is cheaper, but only in the short term. For example, if you were to lease a new Subaru Forester, you might pay $300 per month for the car. If you wer e to buy the same car, you would pay about $400 per month. Over a three-year, you would save $3600-a big savings. But after your lease is over, you have to give the car back. Ma ny people want to lease because they can drive a more expensive car than t hey might otherwise be able to afford. For example, if you spend $300 mon thly on a car, you might be able to lease a new Ford Explorer. For the same price, you might have to buy a used Explorer, or buy a new but much less ex pensive model. A lease，therefore，allows you to drive the latest models of more expensive cars. However, wh atever car you can afford to buy you get to keep it, and it will always have a resell or trade-in (以新旧换) value if you want to upgrade to a new car later. Furthermore, people w ho lease cars are often shocked by how much they must pay when the leas e is over. Most leases limit you to a certain number of miles. If you go over t hat, you must pay for each mile. As a result, you may end up paying thousa nds of dollars in mileage (里程) fees. In addition, when you lease, you have to pay for regular maintena nce and repairs to the vehicle. Since you must return the car finally, you are paying to repair someone else’s car. By now, the benefits of buying over le asing should be clear. Remember: whatever model you can afford to buy, itis yours after you make the payments. There’s no giving back, and that mak es all the difference.【正确答案】12.People usually think leasing a car can save money.（A）True（B）False（C）Not Given【正确答案】A13.Leasing a car costs less in the long term.（A）True（B）False（C）Not Given【正确答案】B14.More people like to lease cars than before.（A）True（B）False（C）Not Given【正确答案】C15.People can lease a car they cannot afford.（A）True（B）False（C）Not Given【正确答案】A16.Young people prefer to lease the latest models of cars.（A）True（B）False（C）Not Given【正确答案】C17.Ford Explorer is the most popular model in the leasing market. （A）True（B）False（C）Not Given【正确答案】C18.People often pay more than they expect for a lease.（A）True（B）False（C）Not Given【正确答案】A19.People need to pay for each mile they drive during the lease. （A）True（B）False（C）Not Given【正确答案】B20.Leasing companies pay for repairs to the leased cars.（A）True（B）False（C）Not Given【正确答案】B21.The author advises people to buy an affordable car.（A）True（B）False（C）Not Given【正确答案】A阅读选择Mental Illness Hits Small Business Owners Hard While there is a growing foc us on mental health in the workplace, there are fewer resources and suppo rt available to those running small businesses. There are many reasons peo ple choose to have their own business being their own boss, working on so mething they love, being able to set their own hours, or having some contr ol over whom they work with. Yet the reality many small business owners f ace is far less attractive-financial stress, long working hours and unclear boundaries between work and family life. And all of these factors can have a huge impact on their me ntal health. Leanne Fawkner is a business owner of an award-winning skin-care range(系列产品). She knows very well the impact that a small business can have on, the mental health of its owner. When her successful business struggled due to t he global financial crisis, she suffered a lot mentally. “As business slowed, I was more and more affected, ” she says. “I couldn’t separate myself from m y business. It was the worst experience of my life. I could no longer go to w ork and was crying all day ?” Fawkner was diagnosed with depression. She had to take several months off work. Fortunately, her husband was able tokeep things going while Fawkner was recovering. She saw a counselor (咨询师) for help and took part in a workplace mental health promotion program . This program was designed for small to medium business owners. “ The st ories on the DVD in the program were so helpful. I was crying because I did n't feel so alone.” For Fawkner, small business owners are overlooked. Whil e employees in larger organizations often have access to employee assistan ce programs, small business owners are struggling on their own.【正确答案】23.One reason to have one’s own business is that one can have more_____ ___.（A）flexible working hours（B）support from others（C）available resources（D）life experience【正确答案】A24.A small business owner usually has________.（A）a more colorful life（B）a bigger profit（C）less stress from work（D）longer working time【正确答案】D25.Fawkner’s business ran into trouble because________.（A）it was taken over by her husband（B）she had a serious mental problem（C）it was hit by the financial crisis（D）she started a-mental health program【正确答案】C26.Fawkner didn’t feel so alone because________.（A）she had her family around（B）she could watch DVD at work（C）others had similar experiences（D）the counselor was helpful to her【正确答案】D27.According to Fawkner, small business owners need more________. （A）financial aid（B）technical knowledge（C）management skills（D）mental health assistance【正确答案】D概括段落大意和补全句子Secrets for a Happier You Some people are naturally blessed with a cheerful character.
