1 . Hundreds of years ago, life was harder than it is today. People didn't have modern machines.
Life today has brought new problems. One of the biggest problems 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 over a city. This kind of quilt is called smog.
Many countries are making rules to fight against 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 do 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 against pollution.

2 . At 8,844.43 meters high, Mount Qomolangma (珠穆朗玛峰) is the tallest mountain on Earth. While it is famous for its beautiful views, parts of the mountain are facing a problem: rubbish (垃圾). Every year, thousands of visitors throw away tons of rubbish, such as bottles and plastic bags.
According to the UN, over 140 tons of rubbish has been left on the mountain. To reduce rubbish, China is limiting (限制) the number of people who are allowed to climb up the north side of the mountain. Only 300 people will be allowed to climb it, and only during spring.
Local people cleaned the mountain last year, removing rubbish at a height of 5,200 meters. They collected about8.4 metric tons (公吨) of rubbish.
This year, the local government plans to spend 4 million yuan on a new clean-up activity. The local government is also setting up stations to sort (分类), recycle and break down rubbish collected from the mountain. A group of artists will also try to turn the rubbish into art works. They will show these works of art to remind people not to leave rubbish when climbing the mountain.
