补充下,我实在对外国人的思维猜测不透,不知道他会怎么给我推荐,是坑我一下,还是救我一把。。邮件恢复如下
I worry that my recommendation may not help you at all. I will have to recommend based on your performance.So my recommendation is very unlikely to be useful. In fact, my worry is that your performance will instead weaken your case. Did you take any other CS course in which you did better? If so, it will be much wiser you can get recommendations from the instructors of those courses.
Please let me know if you still like me to write a letter for you.
