ladies and gentlemen :good evening 。 i am joy and glad to give you a speech about stress , yes , just the topic you see on the screen.
psychologist tell us that stress is a state of worry caused by the problem of living , such as too much work or study , heavy responsibilities , and quickened pace of life 。
statistics show that stress comes from every detail in our life 。 financial problems , poor health , being laid off may be the stress that most adults now suffering 。 as students in the university , we are also under our special stress 。 while study , having to take various tests and submit a project against a deadline may put a great pressure on us 。 and the things make us felt stressed may be our parents’s greater expectations on us than we could reach 。 later , when we are likely to graduate , some other problems will also annoy us 。 i think we will worry a lot about our ability to compete in the job market and how we can best use what we’ve learned at college in our future job 。
the chief problem we should face to is our atitude towards stress 。people usually say they can not live in the sun except they escape from stress 。 it’s unwelcome ! yes , however , very necessary 。 just image a world where stress does not exist and people lead their life in a very comfortable way 。 but is this kind of living condition as perfect as we hope ? without stress , they may feel very satisfied with the current life but lack of power to discover new things 。 too much result in nothing except a countermarch of the society 。 no stress , no development 。 so a certain amount of stress is good 。 it can stimulate us and increase our level of alertness.
and our answer to stress is another vital problem 。 how to do with ourselves when stress suddenly break into our life ? to wave the white flag and admit our unability , to give up to our ideality , or worstly , just to suicide as to put an end to everything … of cause not 。 the principle is to tackle with stress gentlely and harmoniously. we should try our best to release ourselves 。 such as to do some exercise , to linsen to traditional chinese music or classical music to ease our minds and to learn to view these changes of life as challenges 。it’s no use crying over spilt milk 。 only to accept what has happened can solve the problem 。
ok , i think i was under large stress 3 minutes before , but now i am here and have finished my speech 。 here is the last thing i want to add to my topic ,face to it and overcome it ,stress is also a piece of cake.

Dear teachers,dear students:
hello everyone!
The topic of my speech is"the hardness of life"
The vast desert,a tree stand,the show is a monument to the image.
Towering mountains,thousands of tree stand up,as is a magnificent the Great Wall.
The long river,all the trees stood up into a dragon of glory.
We are a symbol of too much,and too much. But I believe that my image is not"the gentlest hands,skin,such as Diorskin"Lin Daiyu,nor is the (差异网☆)modern"unkempt and shabby","Su Qier"。 We are a symbol of hope and vitality. So we show in front of others should be ed without pleats,face without scale,modest and polite gestures exudes a stream of heroic spirit,the image of the vigor and vitality of the modern new youth,a into the embodiment of the spirit of nature.
Someone once said,life is a kind of hardness,integrity and dignity of life is propped up the hardness of bone."Better life"and"the Kui back in the day,and not ashamed on the ground",which is always the traditional virtue of the China. Li Bai's"the eyebrow nengcui Zheyaoshan powerful thing,so that I may not be happy Yan"this awe inspiring atmosphere of the verse and whether it will make those no self-esteem people to shame?Loss of self-esteem is a worthless person,and we as the vanguard of the times,if drown in the darkness forever,or to do a dauntless hero,a flower in the wind and rain sonorous rose. The answer is self-evident. Desert desolate also has the monument stands,Castle Peak again proud,but also have the great wall around,the river again quiet,also there is a dragon in the recumbent. But the time can be changed,our image,our glory remains the same. Because we pride,because we are confident,because we have a fresh life. And because of this,it is a vast desert riparian long,Qingshan was evergreen,the hardness of life is forever.
