一、完形填空
Do you like to travel? How do you usually travel? Most people like to travel by plane because it's the 1 way to get to a place far away. But do you know air travel is bad for the 2? Flying can make about 2.5 per cent of CO₂ emissions(排放) around the world. What's more, it may go up to 5 per cent by 2050. A report says air travel can cause more 3 than other travelling ways. That's why some people start to stop flying or 4 less now.
Katherine Leswing is one of them. When she first started to think about it, she was waiting to catch a flight home in a(n) 5. "I was reading a news story about a woman sailing across the ocean to get to New York. I had 6 thought flying could be so harmful to the environment. She made me think about it 7 for the first time. Then I 8 for information on the internet and was 9 to find out how much CO₂ I made by flying," Katherine said. She 10 it was time for her to make a decision—give up flying.
That gives Katherine a new 11 in travelling. She has relatives in Michigan. She and her husband used to take a short plane ride to visit them. 12 they drive there now. The flight has 13 a family adventure. They go to the beaches in Maine, watch dolphins and fish in Boston and climb the mountains nearby. Their 14 are always full of surprises and they enjoy themselves.
So when you plan to travel next time, 15 a new way instead of taking a plane. You may get unexpected joy!
