Question

【题目】 One cool April 22 morning, people started the day as usual. Yet it was not a normal day. What’s so special about April 22? The answer is because it is Earth Day. People all over the world celebrate this important day. The idea of having a special day to celebrate Earth began in the 1960s. Life was very different then.【1】 Most people had no idea how dirty our air and water were.

On April 22, 1970, twenty million Americans joined the first Earth Day activities. This showed that people really want to do something for the environment. Since then laws have been passed to protect the air, water, land, and animals. The vehicles (汽车) such as cars and buses you ride in must pass tests to make sure they don't cause too much pollution. Thanks to it, cars today give out about half as many bad chemicals as they did in the past.

【2】It's a good thing because they have got a lot of help. The Cuyahoga River in Ohio was so polluted that rubbish and oil on the river even caught fire! Today, the river is cleaner. It no longer burns.【3】

Now the celebration has spread to other countries. More than 175 countries take part each year. Every April 22, millions of people get together to clean and protect the Earth. 【4】 Our job is to put this knowledge to work. You can help keep our planet healthy, too!
