求简易英语演讲稿 三分钟左右.What dose stress mean?when are you under stress and what makes you feel stressed?

ladies and gentleman:
Now,let's share my opinion about stress.
Well,about stress,I think every one here have experiments and the memory about it.
In my humble opinion,things that make us feel stressed are the ones we care most,such as ,a job interview ,or even today's report here.Because we paid much attention,we care it.And then ,it can make us nervous.Or else,maybe you have a high request about yourself or you have set a goal for yourself.To achieve the goal ,we paid much attention and energy .Though,it's uncertain for ourselves to realize it or achieve it.
For me,nowadays,what make me feel under stressed is the final exam.Maybe it 's just because that my parents expect much of me.I think a keen expectation from my parents is also some kind of stress.But I don't think some kind of stress is harmful.On the contrary,I think stress is some kind of force that makes us progress if only you have a correct attitude on it.
Well,my topic is ended.Thank you .
