【題目】Make Your Own Money

It's holiday time, while it's the great time to make some money. Some US teenagers use their imagination and skills to get more money.

New York tennis player Antonio Rivera, 15, serves as a hitter or practice partner for players who want to improve their skills. "You might think, 'why would a parent want to hire (雇傭) me when there are more professional tennis teachers'?" Rivera said. "But as a teen, I can offer my lessons for less money and give a more personal experience."

Many teens turn their extracurricular (課外的) activities into money-making businesses. "If you're good at something—sports, arts, math, science, English, computer software or languages, you can trade that for money," Rivera said.

Harlan Feet, 17, of New York, is a good example. He makes money by getting rid of (消除) computer viruses (病毒) and maintaining (維護(hù)) social media accounts on sites like Facebook, Twitter, or Instagram. He also takes photos of products and posts them online for people who sell goods through online stores.

"Today's kids have grown up with skills that many adults don't like to spend time learning," said Feet, laughing. "That just means money for me." For example, he's found a way to make money by helping families scan (掃描) old photos and save digital versions (數(shù)字版本) of the pictures.

If you have artistic skills, there's a market for you, too. Texan Shyla Boehm, 17, makes and sells handmade things such as small bags and greeting cards. Boehm has set up a shop online and offers her skills online.

1How does Rivera make money?

A.By being a tennis teacher.B.By posting photos online.

C.By selling handmade items.D.By cleaning people's computers.

2From the story, we know Feet is good at ________.

A.sportsB.scienceC.computersD.languages

3What is the story about?

A.What US teenagers usually do on vacation.B.How US teenagers make money on holidays.

C.How US teenagers make plans for their future.D.Why US teenagers should make their own money.
