【推荐2】Hundreds of years ago, life was harder than it is today. People didn't have modern machines. There was no modern medicine, either.
Life today has brought new problems. One of the biggest is pollution. Water pollution has made our rivers and lakes dirty. It kills our fish and pollutes our drinking water. Noise pollution makes us talk louder and become angry more easily. Air pollution is the most serious kind of pollution to all living things in the world.
Cars, planes and factories all pollute our air every day. Sometimes the polluted air is so thick that it is like a quilt (被状物) over a city. This kind of quilt is called smog.
Many countries are making rules to fight pollution. Factories must now clean their water before it is thrown away, and they mustn't let dirty smoke go into the air.
We need to do many other things. We can put waste things in the dustbin and not throw them on the ground. We can go to work by bus or with our friends in the same car. If there are fewer people driving, there will be less pollution.
Rules are not enough. Every person must help to fight pollution.

【推荐3】When he was nine years old, the American boy Milo Cress had a question: How many plastic straws（吸管） do Americans use every day?
He quickly learned there wasn’t a simple answer. The boy tried to work it out himself. Through lots of research（调查）Cress found out that Americans use about 500 million straws every day. In hopes of reducing plastic waste, he founded（建立）the Be Straw Free project in 2011.
Cress started the project in his hometown—Burlington, Vermont. He asked a local restaurant to stop offering straws with every drink order. It was a simple change. However, it would save money. And by doing that, the restaurant would cut down on its straw use by 50 percent.
For the years that followed, Cress tried to spread（传播） his project across the United States. More and more restaurants agreed to join. They stop providing the customer（顾客） with a straw unless he or she asks for one. Last April, Seattle became the first American city to completely ban（禁 止） plastic straws.
Plastic pollution has been one of the most serious problems today. According to scientists, more than eight million tons of plastic end up in the ocean each year. Plastic straws are especially terrible. They make it easy for people to get comfortable with single-use plastics.
After his project became popular, Cress took his findings on the road. He has spoken to tens of thousands of students around the world. He wants to encourage more people to say no to plastic straws.
“Focusing（聚焦） on straws is one simple step we all could take,” Cress says. “And it makes me feel that I, as a kid, could make a difference, too.”
