It’s very important that we all recycle. In nature, everything 1 again. For example, when an animal dies, it becomes 2 animal’s food. Nothing is wasted. But humans have created things like plastic bags 3 can’t be broken down by nature. Our rubbish kills animals and 4 water and soil. ___5 we continue making too much rubbish, the problem will only get worse. If nature can’t reuse the rubbish, we must recycle 6 .
We should clean up the rubbish we’ve made because nature can’t. Recycling is also the right thing to do for another reason. The earth is rich in natural materials like water and trees, 7 these materials are not endless. We use up our natural materials much 8 than the earth is able to reproduce them. For example, each year we cut 9 more than 6, 000 square miles of forest. But it takes an average of 25 years for a new tree 10 .
Recycling can help us save the earth, so let’s take action right now.

(A)
Millvina Dean, Titanic’s last survivor(幸存者), died on May 31, 2009 in Southampton. She was 97 and had been in poor health for several weeks.
The youngest of the ship’s 705 survivors, Ms. Dean was only 9 weeks old when the Titanic hit an iceberg(冰山) on the night of April 14, 1912. She survived with her mother and her 2-year-old brother. Mr. Dean, 29, was taking his family to a new life in Kansas City. He planned to run a tobacconist’s (烟草商) shop there. He was among more than 1,500 passengers and crew members who died in the sinking.
Ms. Dean never married and spent her working life in Southampton. For many years after the sinking, she never spoke of it to people she met or worked with, partly because she remembered nothing about it and partly because she did not want to be seen as drawing attention to herself.
But that changed after September 1, 1985 when the wreck(残骸) of the Titanic was discovered. That set off a wave of interest in the ship, especially after the movie Titanic. “They found the wreck and after they found the wreck, they found me,” she said.
In the last 20 years of her life, she went to gatherings(聚会) in the USA, Canada and a number of European countries to take part in events related to the sinking. She said she had learned from her mother about what happened during the sinking.
Ms. Dean had never seen Titanic. She explained she was unwilling to be reminded of what had happened to her father.

Let’s go green!
It’s everyone’s duty to make the earth a green home. We can do something to go green in our daily lives.
Firstly, make sure that appliances are turned off when they are not used, which can help us save energy. Secondly, it is also important to save water. We should form the habit of turning off the tap after it is used. What’s more, we should save paper by using both sides of it. Remember not to use disposables. And try to avoid using plastic bags which are harmful to the environment.
In a word, going green is very important. Let’s work together to create a greener world from now on.

经典范文
Water is very important to humans. We can’t live without water. The problem is that water pollution is becoming worse and worse. What’s more, the amount of water suitable to drink is falling now. What should we do?
First, we shouldn’t pour dirty water into rivers, and we shouldn’t throw rubbish into them, either. These can help to protect water. Then, we must do something to stop other pollution to water, and try our best to reuse waste water. Finally, we had better plant more trees. It’s also useful for protecting water.
If we don’t protect water, the last drip of it will be a teardrop. I hope that everyone plays a role in saving water.

参考范文
There has been frequent haze in the last few years in many cities. It’s high time people started paying attention to air pollution.
What are the reasons behind the terrible weather? First, the number of cars has been increasing in the last few years, and they produce too much poisonous gas. Second, a lot of rubbish is burnt without following the rules. Besides, smoke and flying dust from chemical plants add to the problem.
It is time for us to fight against air pollution. We should use buses more often instead of driving cars. Planting more trees can also help to improve the air quality.
