How to Save the North Pole
　　As we all know, our North Pole is ill. She often cries for help recently. How to save our farthest friend of the earth is an important problem for us. I have some good ways to help save her.
　　First of all, we should control the raising temperature. We should live a low carbon life. Besides, we should take steps to protect the environment. We shouldn’t cut down trees freely and we should plant more trees every year. In the end, we need to work together with other countries to give the North Pole a bright future.

用法总结　
“祈使句+or +另一个句子”意为“如果不做某事,某人就会做某事”。 or在此处表示“否则”之意。例如:
Study hard, or you will fall behind others. 你如果不努力学习,就会落后于他人。
知识拓展　
“祈使句+ and+另一个句子”意为“如果你做某事,你就会做某事”,与“If you do sth., you will do sth.”构成同义句。
素养训练　用or或and填空。
1.Try your best, you will pass the exam easily.
2.Run faster, you will fall behind others.
In fact, I’ve got many plants and animals. 事实上,我有许多植物和动物。
用法总结　
in fact=as a matter of fact,意为“ 实际上;事实上”。 I’ve got意为“我有……”,属于英式英语,美式英语中用“ I have...”表示。 例如:
I’ve got a nice bedroom. 我有一个美丽的卧室。

two hundred years 意为“200年”。常见的计量单位: hundred 百; thousand 千; million 百万; billion 十亿。当名词复数前有基数词修饰计量单位时,计量单位不加s,例如:five thousand 五千。
知识拓展　
hundreds of 成百上千的; thousands of 成千上万的; millions of 数以百万计的; billions of 数以十亿计的。如果计量单位前没有具体数字修饰时,计量单位加s,常跟of 连用。
