如果您要张贴作业，请至少尝试进行看起来您尝试自己做某事！

我们不做您的作业:这是有原因的.在这里，您可以考虑自己被告知的内容，并尝试理解它.也可以在那里帮助您的导师识别您的弱点，并将更多的注意力放在补救措施上.

自己尝试一下，或者学一下神奇的话:您要用它炸薯条吗?"

If you are going to post your homework, at least try to make it look like you have attempted to do something yourself!

We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.

Try it yourself, or learn the Magic Words: "Do you want fries with that?"
