演讲论题：同性恋婚姻homosexual marriage should be banned according to the international investigation, by 2004, the proportion of gay isaround two to five percent of the whole population. and this ratio has been on therise ever since, especially in the last few years. we know, many countries, such asthe us, china, russia, india and so on, are now confronted with the problem of agingpopulation caused by low birth rates. once it’s allowed to get married with someoneof the same sex, they don’t have their own kids, and then the birth rates may evenbe lower. and what’s more, once homosexual marriage is legalized, many potentialgays will join the rank without scruple. then the situation will be more serious thannow. if this is the case, a series of social problems may be created following theaging-population problem, such as heaver social burdens, greater demand for expenditure for social security and so forth…. life will be more difficult forour son.some may say there are ways to solve the problem of children. by adopting, goingto a sperm bank or borrowing uterine, or doing whatever can be done with science andtechnology. but not to mention moral problems or traditional conceptions, thetechnology is far from mature. and it increases the risk of variation. even if theyhave a healthy baby ultimately, will the kids turn out to be well? will the kids acceptthe fact that both his parents are men or women? will they feel it abnormal to growup in a strange family and be able to endure the pressure of public opinion? or willthey turn out to be homosexuals, either, because their growing environment tells themit is normal. the truth is it is not decent, not right, not normal. the presenthomosexual population is already plagued by the sick disease; how can we risk ournext generation?some may also say true love should not be repressed. everyone is entitled to truelove regardless of gender. true love is not guilty: this may be the reason why somepeople are in favor of homosexual marriage. but are you sure you really know thiskind of love? the american sexologist junky said that many homosexuals resulted fromthe mental distortion. homosexuality，more often than not, is a result ofpsychological problems, which may have stemmed from the unfortunate experience in childhood, having been hurt in aheterosexual love, wrongly pursuing the sexual pleasure or some other psychologicalproblems. legalization of homosexual marriage will mean our tolerant attitude to amental disease like depression. we will be leaving this sickness to luck. then itis inhumanity and brutality. could we just stand by and watch it die its own course?of course not. for all of these reasons, how could we ignore the mental illness of homosexuals to legalize homosexual marriages? how could we disregard thehappiness and health of our next generation to legalize homosexual marriages? howcould we leave the development of our society to legalize homosexual marriages? aslong as we have sense of responsibility, the answer should be definitely not.篇二：persuade speech 劝说性英语演讲范文stop the rumor with wisdomdear classmates, i believe most of us have heared about at least 3 internet rumors.such as: the world would end in 2012, the iodine in salt can protect people from nuclearradiation. in fact, we may have seen more rumors than we thought, that is becauseon the one hand, with the help of internet, rumors are increasing sincemaking andspreading them is getting more and more convenient. on the other hand, some of themwere disguised withauthority or science or even friendly reminder, which make it moredifficult to see through.firstly, we should never be the source of rumors. i know most of us won’t makerumors on purpose, but we can’t ensure what we said won’t be used by other individualsintentionally, or our original meaningswon’t be misinterpreted.although the internetis open and free, that doesn’t mean we can say whatever we want without a secondthought.secondly, we shouldn’t help the spread of internet rumors. because the wilderthe rumor spreaded, the more damage it will cause. we all know thatthree peoplespreading reports of a tiger make you believe there is one around. thanks to theinternet, now we can spread the rumor with only one share button. even though we didn’t take the rumor for real when we push the button, it is possible for others to believethese rumors because they trust us. in the worst situation, our reputation may bedestoried by this reckless behavior. last but not least, we should try our best to terminate the rumor. and that dependson our wisdom.in most cases, the rumors always pretend to be the truth, (有图有真相)for that most of us would rather believe than not. but in fact, that doesn’t benefitanyone. the right way is keepingsuspicious about what we seeand hear, especiallyofthose shocking or illogical. and using our professnial knowledge to make the rightchoice.as the old saying goes, the wise men ended rumours. i believe as graduate students,we have enough wisdom to be the terminators of rumor. so, let’s stop the rumor withwisdom.篇三：说服型演讲稿116721019 劝服型演讲谢婧妤沟通大纲中国民歌是中国人民唱歌走调的重要因素一、听众是：同龄人二、成果：让大家相信中国民歌是中国人民唱歌走调的重要因素1、结束后，听众了解/认同??：由于从小就学习高难度的中国民歌才导致了中国人民唱歌走调2、为实现这一结果，听众需知：1）唱歌的音准是与一个人找音距的能力有关的，音距就是一个音到另一个音的距离；2）从小学开始我们的音乐课本就充斥着各种高难度的中国民歌，而中国民歌的音域跨度都比较大，让还处于学习阶段的我们难以找到准确的音距，导致了后来的音准问题；3）外国的民歌大部分为比较简单的音调，难度较小，容易找到音距，比如像在国内很红的《送别》的曲子也是从国外传进来的，简单易学朗朗上口。
