不懂英语作文的要求
Your composition will be graded according to clarity,accuracy and meaningfulness怎么才算做到?
Your writing ought to contain three parts,your viewpoint,the supporting ideas,and the conclusion.其中viewpoint和supporting 有什么联系或区别?
Therefore,what is your attitude toward the natural disasters?What shall we do to prevent us from being simply destroyed?What kind of role did we play in the causes of those dreadful disasters?Your writing ought to contain three parts,your viewpoint,the supporting ideas,and the conclusion.
这段要求告诉我们本身有三个方面要写，又说“包含三部分”，应该怎么写？是分三段回答三个问题？那最后一句话又有什么限制要求？
不过我想等会再看看。
