2020年，一场突如其来的新冠病毒肺炎让我们再次重新审视了人类与自然的关系。请以”It's Our Duty To Protect Our Environment”为题，写一篇不少于60单词的作文。
It's Our Duty To Protect Our Environment
保护环境是我们的义务
It's our duty to protect our environment. Where do we live? The earth. The earth is the only one place we live in. So you know how important the environment is.
保护环境是我们的义务。我们居住在哪里？地球。地球是我们唯一居住的地方，所以可想而知环境对于我们的重要性。
But now, some people are harming the environment, like cutting down trees, drawing pictures on public walls, littering onto the ground. It's terrible if we still do it.
但是现在，很多人都在破坏环境，比如砍伐树木，在公共墙壁上乱涂乱画，随地扔垃圾。如果我们继续这样下去是非常可怕的。
Now, it's time for all the people in the society to protect the environment. It's our duty. It needs each of us to make a contribution to improving the environment. We should make our environment more and more beautiful.
现在，是人们保护环境的时候了，这是我们的义务，我们都要为改善环境做贡献，我们应该努力让我们
的环境变得更好。
点评：作者多用学过的词语，不但保证了正确，还巩固了所学的知识，并且注意句型的多样化，如长句、短句、疑问句，使用了“if，so，now，but”等词，整篇文章读起来朗朗上口。实际上，写文章就像串珠子，连接词就在于把一个个单词串起来。
议论文常用的句型有：
1、论点：Computer is important.We must learn English well.It's very important for us to...In my opinion...
2、论证过程常用一些衔接词可使文章读起来流畅、紧凑。如：Firstly, ... Secondly, ... Lastly, ... Above all, ... 等。
3、结尾强调观点，最好用不同的句型来表达相同的观点，如：So we must...So it's very important for us to...I believe...We should...
