推荐答案

我们不做你的作业:这是有原因的。它就是为了让你思考你被告知的事情,并试着理解它。它也在那里,以便您的导师可以识别您身体虚弱的区域,并将更多的注意力集中在补救措施上。



亲自尝试,你可能会发现它不是和你想的一样困难!
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, you may find it is not as difficult as you think!
