麻烦帮审一篇英语演讲稿啊~4分钟的演讲.
Good morning ladies and gentlemen .Thank you for coming ,it`s myhonor to stand here and give you a speech .My topic is learn from yesterday,seize the day and faith in the future.
Since we were born ,we all stand on three points .They are yesterday,today and tomorrow .I learned a lot from yesterday ,I work hard today and Ihave hope in the future .
There is one day in every week about which we should not worried:yesterday with its mistakes and cares ,its faults and blunders ,its aches andpains .Yesterday is gone ,but it wouldn`t gone in vain .It gave us many sweetmemories .And something we can learn from .Yesterday holds many lessons for us,if we neglect to learn it ,we may unnecessarily repeat mistakes that we havealready made .Yesterday might be painful ,but without studying the lessons ofthe past ,how can we obtain a better future .
Yesterday has gone .we should think about today instead of beingobsessed in the past .Today is the very minute and second I have now .What eachof us is doing this minute may be the most important event in history for us.We have decided to invest our resources in this opportunity rather than anyother .It remind me a movie line in DEAD POETS SOCIETY :Carpe diem ,seize theday boys and make your lives extraordinary .Today is the bridge between todayand tomorrow ,don`t let yesterday use up too much of today ,seize the day isthe basis for success in tomorrow.
Yesterday and today will allgone with the wind .From those days ,I learn to believe in tomorrow .But as weall know ,an economic hurricane has swept the world ,creating so many crisisthat opportunity comes to be seen as a zero sum game ,in which your dream comeat my expanse .Many people feel their dreams slipping away and lose their faithin the future little by little .But should we succumb to a race to the bottomand self-abandonment that in the end helps no one No ,we should haveconfidence ,we must believe that we can seize the opportunities ahead and makethe future work for us .This is not blind optimism or synthetic confidence toconsole people .It`s the practical affirmation for our time and our faith inthe future .And it means ,also ,taking full responsibility for our own lives.We must know that we many face challenges and discrimination in our own live,we must always believe that we can write our own destiny .The Greek proverb,what dose it say Why dose anybody plant the seeds of a tree whose shade theywill never see The answer is because they look to the future .
Yesterday is history ,learn from it ;Today is a gift ,seize it;Tomorrow is a mystery ,fight for it .And I believe you ,the people,that havethe vision to work hard every day ,are also the people with the vision to seeka bright future .

1.第四行：Since we were born ,we all stand on three points ,They are（改成that is）yesterday,today and tomorrow
that在文中通常指上文提到的事,这里用that is表示对上文three points 的解释
2.I（改成we） learned a lot from yesterday ,I（省略I）work hard today and I（省略I）have hope in the future .
因为这是一篇演讲稿,所以建议演讲者不要以第一人称单数做主语.通篇应当努力与观众产生共鸣.后面的主语可以省略,这样可以使你的演讲变得有气势
3.Today is the bridge between today（改成yesterday）and tomorrow
因为在今天,人们是在过去的基础上进一步学习努力成长,为了达成未来的目标.（个人建议哈）
其他的都还可以.
