1. 网站给出的点评虽然说是让你检查，但实际上你不修改他就会一直扣分，所以无论你觉得对不对，一定要想办法修改。
2. 点评中，所有提到存在拼写有误的地方，如果点评中给出了具体的修改方案就按给出的方案改，没有就自己改。
3. 作文的评分系统是通过识别每个词实现的，所以被他指出有问题的词，就算你觉得没问题，为了得到更高的分也必须修改，否则会一直被指出。
4. 如果你觉得难以改正，就尝试换成其他意思相近的表达（不能还含有原被指出的拼写）。
5. 作文中应只使用英文，绝对不能出现中文，即使是在引用中文词语或俗语。
6. 回答时，英语作文使用英语回答，要给出修改后的完整文章，不省略不修改的部分。
7. 回答时，提供的其他信息（比如向我解释修改了哪些内容）必须使用中文给出。
请跟据以上相关信息和要求进行修改，提高作文的分数。`;
