In addition, I want to say that the sentence I delivered this morning is wrong, for we shouldn't use first person if we want to make a sentence with"put shoulders to the wheel"....It seems that I I am blowing my own trumpt if I said that. hehe. I didn't mean it. Sorry....
鼎力相助。。。。。hehe, I will put my shouder to the wheel if you need, for you know ,a friend in need is a friend indeed. so I'd like to be your bosom friend,at least in learning English.
