初中生英语励志演讲稿精选范文 篇1

here's one of the culprits. this is the letter sheen, and it makes the sound we think of as sh -- “sh.“ it's also the very first letter of the word shalan, which means “something“ just like the the english word “something“ -- some undefined, unknown thing.

now in arabic, we can make this definite by adding the definite article “al.“ so this is al-shalan -- the unknown thing. and this is a word that appears throughout early mathematics, such as this 10th century derivation of proofs.

the problem for the medieval spanish scholars who were tasked with translating this material is that the letter sheen and the word shalan can't be rendered into spanish because spanish doesn't have that sh, that “sh“ sound. so by convention, they created a rule in which they borrowed the ck sound, “ck“ sound, from the classical greek in the form of the letter kai.

later when this material was translated into a common european language, which is to say latin, they simply replaced the greek kai with the latin x. and once that happened, once this material was in latin, it formed the basis for mathematics textbooks for almost 600 years.

but now we have the answer to our question. why is it that x is the unknown? x is the unknown because you can't say “sh“ in spanish. (laughter) and i thought that was worth sharing.

Nature has provided us with many kinds of resources. All most everything we use in our everyday life comes from Nature. The food we eat, the water we drink, the clothes we wear, the concrete and bricks to build our houses, the materials to make bikes we ride, etc, all come originally from Nature.

People have been making use of these natural supplies for thousands of years. With the development of technology and the increase of the population, the amount and range of mate rials taken has increased. It is estimated that this tread will continue in the years to come.

However, natural resouces are not in exhaustible. Some resources are already nearly used up. For example, the end of the world's fuel is already within sight. Such an essential daily item as water is in short supply in many parts of the world. We can no longer thoughtlessly use the many resources provided by. Nature. We must learn to conserve what remains.

honorable judges and dear friends, my name is maer dongyan, i’m very happy today to stand here to share my speech, my imagination, and my story as an air traffic controller with all of you.

i, as a 35-year-old air traffic controller, have been working on the tower for nearly ten years. through these years’ working, i really come to love this . besides, as the husband of my beloved, the father of my 8-year-old daughter, and the son of my old parents, i also love my family, a happy family.

however, it has been really hard to coordinate my work and my family.

it’s generally considered great to be an air traffic controller by the public, for the is believed to be well-paid and quite easy. i was also one of them before i started the work. but things have been entirely different from what i used to think. as an air traffic controller of the new century, we’re facing tasks and barriers greater and harder than ever, that is, we have to ensure the safety and order of the fast-developing civil aviation. we’re burdened with pressure, responsibilities, the trust of hundreds of pilots, the lives of tens of thousands of passengers, and the hopes of millions of families. every step we take, every word we say is connected to the safety of passengers. and disasters may occur if we’re even a little bit careless. then, how can that be easy?

as a man who owns a family, i also have to take care of my family. still, it isn’t that easy. since i took the 10 years ago, i haven’t had enough time to be with my family. so many festivals have i spend with microphones, but not my family and friends, just because my needs me. so many times have my wifecomplained about my returning home late and having meals outside often, just because my needs me. and so many times, my mom or dad is sick in bed, but i cannot be there with them in time, just because my needs me. i cannot fully devote myself to my family because my needs me, a lot of people need me. and again, as a man with a family, how can that be easy?

even though i’m not competent as a father, a husband, and a son, i still love my family. my daughter once said that it was her happiest time to see me back from work. and it’s the same with me. i’m pleased and grateful to see that my family can support and understand my work and my little devotion to them.

i have made many sacrifices as an air traffic controller. i really feel sorry for my family. but as i help pilots find their destinations under terrible weather conditions, and then hear “thanks” from them, i’m satisfied. and as i see planes taking off and landing safely, and make sure that hundreds more families can get together, i’m comforted. i even seem to be able to see the happy smiles on their faces.

such is my , though i cannot enjoy much of the happiness my family brings to me, i can experience the sense of responsibility through my work. i’ll never regret this, regret choosing my . it is through these years that i know what responsibility and devotion really mean. and it is through these years that i realize what family really means to me---supporting and understanding. i really appreciate them.

with my family as an anchor for me, i firmly believe that i can overcome all the difficulties on my way, and make a contribution to the cause of air traffic control. and i believe, i am, and always will be a member of civil aviation, and my family as well.

that’s all for my speech today, thank you very much for your listening.
