乳癌患者，发现同侧腋下及胸骨旁有淋巴结转移，但一般情况尚可，宜行 A．乳癌扩大根治术

Dear friends,

As we can see, the environment around us is getting worse other than better. Our life and health have affected greatly. The earth is our home, but we have a duty to take care of it, not only for ourselves but for future generations. Fortunate, more and more people have become aware of this problem. Many effectively measures have been taken by the government to deal with them.

As a student, I think we should do what we can improve the environment. First, go to school on feet or by bike as often as possible. Second, turn on the lights and other electrical appliances before leaving the room. Third, never throw rubbish here and there.

It’s time that we do something to protect our environment.
