小学四年级演讲稿小学四年级演讲稿大家好!在这个阳光明媚的下午，我走上了讲台，竞选班长这个光荣的职位! 这是我第一次竞选班长，我可能没有老班长遇事时那么沉着冷静;没有那些自信心强的同学处事落落大方，但这是班级给我的一次锻炼机会，我非常地珍惜。我相信，世上无难事，只怕有心人，只要我用心去做，一定会带领我们四、一班干出成绩。我竞选班长的优势是热情开朗、热爱集体、团团结同学、拥有爱心和责任任心。我认为，班长这一职职位需要一个有能力有爱心心的人来担当，我相信我有有这个能力。 假如我当上上了班长，我一定会严格要要求自己，为同学树立榜样样;还会想同学之所想，急急同学之所急，时刻准备为为同学们服务。相信在我们们的共同努力下，充分发挥挥每个人的聪明才智，我们们的班级一定会成为一个团团结向上、积极进取的集体体。 假如我当上了班长，我会把班级活动作为展示示我们特长、爱好的场所，使同学们把学习当作一种种乐趣，在集体里互帮互助助。 假如我当上了班长，我会每周推荐几本好书，帮助大家买好书，读好书书。当然竞选班长也非易易事，因此失败了也没关系系，只要我努力奋斗过，我我就是最棒的!再说了，“是金子总会发光”，只要要我不放弃，努力拼搏，一一定会让自己竞选成功。请大家支持我，相信我!投我一票吧! 谢谢!-general inntroductioni am a thirdd year masteer major in automation at shanghaii jiao tong university, p. r. chinna. with treemendous intterest in inndustrial enngineering, i am writinng to apply for acceptaance into yoour ph.d. grraduate cattion backgrooundin 19955, i enteredd the nanjinng universitty of sciencce & technollogy (nust) - widely cconsidered oone of the cchinas bestt engineerinng schools. during the following uundergraduatte study, myy academic rrecords keptt distinguisshed among tthe whole deepartment. ii was granteed first claaprize everyy semester,iin 1999, i ggot the privvilege to ennter the graaduate progrram waived oof the admisssion test.at the periood of my graaduate studyy, my overalll gpa(3.77/4.0) rankedd top 5% in the departmment. in thee second semmester, i beecame teacheer assistantt that is giiven to taleented and maatured studeents only. tthis year, ii won the accer scholarsship as the one and onlly candidatee in my depaartment, whiich is the uultimate acccolade for ddistinguisheed students endowed by my universiity. presenttly, i am prreparing my graduation thesis and trying for the honor oof excellentt graduationn thesis.reesearch expeerience and academic acctivitywhenn a sophomorre, i joinedd the associiation of aii enthusiastt and began to narrow ddown my inteerest for myy future ressearch. withh the tool oof opengl annd matlab, ii designed aa simulationn program foor transporttation schedduling systeem. it is noow widely ussed by diffeerent researrch groups iin nust. i aassumed and fulfilled aa sewage anaalysis & disspose projecct for nanjiing sewage ttreatment pllant. this wwas my firstt practice tto convert aa laboratoryy idea to a commercial product.inn retrospectt, i find myyself standiing on a sollid basis inn both theorry and experrience, whicch has prepaared me for the ph.d. pprogram. my future reseearch intereests includee: network sscheduling pproblem, heuuristic algoorithm reseaarch (especiially
