帮我看看我的英语作文有哪些问题?请指出并修改!
when professor entered the classroom,The words "welcome resume professor"on the blackboard draw professo's attention.
professor had been injured in a car accident,and had had several times operations in the nearby hospital.the doctor calculated the possible of his survival would no more than 10% .now,not only had he recovered but also he could resume teaching.every students was exited when they saw the professor,about many minutes later the class cool down.
这是对一段中文的翻译,其中instant,cool down,draw sb's attentation,injure,resume,calculate,nearby必须要用!
