大家好!我们都知道,许多伟大的发明给我们的生活带来了巨大的变化。我认为我们学生也可以发明一些东西。
today i'm glad to be here to talk about what i'd like to invent - a chairthat's good for students' health. it will be made of wood. there will be twosensors in it -- one on the seat, and the other on the back of the chair. whenthe student doesn't sit straight, the chair will remind him .if he sits on thechair for over one hour ,it will make a noise. it won't stop until the studentstands up and leaves.
今天我很高兴到这里来谈论我想发明——一把椅子,对学生的健康有好处。这将是用木头做的。将会有两个传感器，一个在椅子上，另一个在椅子后背。当学生不坐直,椅子会提醒他。如果他坐在椅子上超过一个小时,这将发出噪音。它不会停止,直到学生站起来,离开了。
it will be a useful invention, won't it ?
这将是一个有用的发明,不是吗?

what is my favorite invention?
we knew there had been many inventions at the last century, for example,electric light bulb, telephone, phonograph, mimeograph machine, automobile,airplane, atomic weapon, computer and so on. what is my favorite invention?
personally, my favorite invention should be computer. in the old days, manyscientists took much time to calculate and deal with research data, so theeffective time in doing research was relatively shortened. for millions of timesof calculating per second by computer, the researchers may have enough time tostudy more important issues. the processing of experiment results became verysimple and easy. aren’t those all evidences that the computer is one of thegreatest inventions in the last century, are those?

learn how to say no
we've all been taught that we should help people. it is the right thing to do and will make us popular with others. it may even win us favors in return. however, we must be realistic. we can't say yes to every request. if we did, we would fail or go crazy for sure. sometimes we simply don't have the time to help. in this case, we must know how to say no politely.
when we need to say no, here is one method we can try. first, we should tell the truth. if we really can't do something, we should just say so. second, we should remember to refuse requests politely. we must communicate clearly, but must also be sincere and sympathetic. a true friend will understand. finally, we must not feel guilty about saying no. sometimes refusing others is the right thing to do. it can save ourselves, and them, a lot of trouble. in short, we cannot please everyone all the time. refusing favors is a part of life.

i heard a word"don`t give , just be you.because life`s too short tobeanybody else."i think what this word express is so yeah,so i wanna you tomemorize it.
everyone has a beautiful dream and personal life principle.but on the waythat we hunt for the keys of acheving our dreams,there are many difficultiesappearing,thus,several timid men give in to them,one after another,some peaplelost their first dreams and even themselves.so!many characters and pretty orhandsome stars around us,we are obesessed with some of those,and even ad occeanof peaple volunteer to imitate those idols.however,as we turn back,we will findin surprise,the tree is still the old tree,the house is still,......theeverything is still the same.we didn`t change them a little.
the same as our competitions,teachers always say:"you`d better read moreessays and memorize some perfect or wonderful sentenses,it`s helpful for yourwriting level."well!i don`t think so! personally,i feel we must keep on ourstyles and priciple,due to this,when readers read our essays,they might learnabout us better,therefore we will become happier to make the life colorful andmeaningful.so,i support that we read more books,rather than recite moreessays.
being true to yourself implies if you are delighted,then you laugh,if youare sad,then you cry,don`t hide your mood,do not be hypocritical.go on yourdream which is deep in your hear. you can`t become the other like magic,becausethere is no such thing as magic in the wold,ok!let`s stand in front of themirror,carefully look at ourselves.say:calm down.don`t get anything to botheryour heart,just be true to yourself.
