初中生英语课前的演讲稿（精选3篇）
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.
Hello! Every one. My name is XuJiaWei, from Class 3 Grade 7.
Please think a minute! I heard a funny true story about this guy who goes to the gym to exercise and work out each week. He takes 20 minutes to change his clothes. Then he walks around the gym talking with different people.
After that, he reads the newspaper. Finally, he does a few stretches and 5 minutes of exercises. Then he takes a hot steam bath before going home. So in the whole 2 hours he’s at the gym, he only spends 5 minutes exercising! One day, someone heard this man saying:“I don’t understand it. I go the the gym almost everyday, but I never seem to lose weight.” But every body at the gym knows why, because they see this guy there doing everything except the main thing exercise!
You see, it’s important that we keep the main thing. And if you want to be successful. In your job, business, or managing your family, or your studies, whatever we do, we must get the main thing done. Instead of wasting our time and energy doing things that aren’t important. Because it is easy to get side-tracked doing other things that might be easier or more fun to do.
Just think a minute…
That’s all for my today’s speech, thanks.
What success means to me?
Honorable judges, distinguished guests, ladies and gentlemen:
It is a great honor and pleasure to be here on this beautiful and wonderful Sunday evening to share with you my sentiments about life and passion about my homeland.
As we known, our ancestors have made great miracles on this fertile land, and we are still making miracles. Who can ignore the facts, that we have established ourselves as a great nation in the world, that we have devised our own nuclear weapons, that we have successfully sent our satellite into space, that our GNP ranks NO. 7 in the world, that the 29th Olympic games will be held in 20xx? It is true that we have experienced plunders by other nations, we have experienced wars. But based on such ruins, there still stand our nation China, unyielding and unconquerable.
An American tourist said:“ China has a long history of 5,000 years, but the US just has a history of 200 years. 5,000 years ago, China took the first lead in the world, but now it is the US that is leading. ”My heart was deeply touched by these words. Yes it is true that we are still a developing nation, but it does not mean we can despise ourselves. We have such a long standing history, we have such abundant resources, we have such intelligent and diligent people, we have enough to be proud of. I think we have enough reasons to say proudly: we are sure to take the first lead in the world in the future again, for the problem is big, but our ambition is even bigger; our challenge is great, but our will is even greater.
About personality, especially the youth, I think it is not a time of life, it is a state of mind. It is not a matter of rosy cheeks, red lips and supple knee, it is a matter of will, a quality of imagination, a vigor of emotions. Youth means a temperamental predominance of the courage. At the same time, I remember an old Chinese proverb: one minute does farm work, one minute harvest. I think we should make good use of everyday, so that we can achieve great success and our country will gain the prosperity.
Everyone here, let us find the confidence to conquer our limitation and embrace the new challenges. Let us contribute our efforts and create a glorious future for our homeland.
