This might seem crazy, but many students in the United States do jobs 1 being paid! Yes, they volunteer. And they like it, too! Many girls volunteer to work in hospitals. Other kids volunteer to work at zoos or in an old people's home.2 they don't get paid, they get to spend their day 3 animals. There's also a Big Brother Foundation in the US where older kids often train younger kids and 4 them with their homework.
Maybe you don't have the same opportunities (机会) in 5 to volunteer as kids in the US have. But don't worry! If you volunteer to help people, there are many 6. You can volunteer to help at a hospital, you can help elderly people, or you can volunteer to 7 rubbish on the ground.
Why volunteer? Volunteer work gives you experience. It might help you get a dream 8in the future. Doing volunteer work shows that you care for 9 and are generous (慷慨的) with your time. Some bosses like people who do these things. 10 helping others is helping yourself, and volunteering also makes you feel happier. Try it! It could be the best improvement to your summer.
