第1篇 英語(yǔ)三分鐘演講稿：我與祖國(guó)
a young idler,an old beggar almost everyone knows the famous chinese saying：a young idler，an old beggar.
throughout history，we have seen many cases in which this saying has again and again proved to be true.
it goes without saying that the youth is the best time of life，during which ones mental and physical states are at their peaks.
it takes relatively less time and pains to learn or accept new things in a world full of changes and rapid developments.
in addition，one is less likely to be under great pressure from career，family and health problems when young.
therefore，a fresh mind plus enormous energy will ensure success in different aspects of life.
of course，we all know：no pains，no gains.
if we dont make every effort to make good use of the advantages youth brings us，it is impossible to achieve any goals.
as students，we should now try our best to learn all the subjects well so that we can be well prepared for the challenges that we will face in the future.

第3篇 ted英語(yǔ)演講：我與蚊子的愛(ài)恨情仇
why i study the most dangerous animal on earth — mosquitoe
演講者：fredros okumu
| 中英對(duì)照演講稿 |
i guess because i'm from tanzania i have a responsibility to welcome all of you once again. thank you for coming.
我猜，由于我來(lái)自坦桑尼亞我有責(zé)任再次歡迎你們，謝謝你們的到來(lái)。
so, first of all, before we start, how many of you in the audience have been in the past a victim of this bug here? we apologize on behalf of all the mosquito catchers.
在演講開(kāi)始前，首先我想問(wèn)一下各位在座的朋友是否都受過(guò)蚊蟲叮咬之苦?我代表所有捕蚊者向大家道歉。
ladies and gentlemen, imagine getting seven infectious mosquito bites every day. that's 2,555 infectious bites every year.when i was in college, i moved to the kilombero river valley in the southeastern part of tanzania. this is historically one of the most malariouszones in the world at that time. life here was difficult. in its later stages malaria manifested with e_treme seizures locally known as degedege. it's killed both women and men, adults and children, without mercy.
女士們，先生們想象一下，如果每天被攜帶傳染源的蚊子叮咬7次那一年就是2555次。我上大學(xué)的時(shí)候，搬到了坐落于坦桑尼亞南部的基隆貝羅河谷村。在當(dāng)時(shí)，那里是有史以來(lái)全世界瘧疾的高發(fā)區(qū)。那兒的生活很艱辛在瘧疾晚期它主要表現(xiàn)為極嚴(yán)重的抽搐，當(dāng)?shù)胤Q為“degedege'無(wú)論男女老少都難以幸免。
my home institution, ifakara healthinstitute, began in this valley in the 1950s to address priority health needsfor the local communities. in fact, the name ifakara refers to a place you go to die, which is a reflection of what life used to be here in the days before organized public health care. when i first moved here, my primary role was toestimate how much malaria transmission was going on across the villages and which mosquitoes were transmitting the disease.
我家鄉(xiāng)的研究機(jī)構(gòu)，‘ifakara研究所‘于上世紀(jì)50年代在這個(gè)村莊成立為當(dāng)?shù)厣鐓^(qū)提供重要的健康保障。實(shí)際上，ifakara的意思是人死時(shí)會(huì)去的地方它反映了沒(méi)有公共醫(yī)療保障之前當(dāng)?shù)氐纳顮顩r。當(dāng)我第一次搬到這里來(lái)的時(shí)候我主要的工作就是去估計(jì)在這個(gè)村子里有多少瘧疾傳播的案例并找出是哪種蚊子在傳播疾病。
so my colleague and myself came 30 kilometers south of ifakara town across the river. every evening we went into the villages with flashlights and siphons. we rolled up our trousers, and waited for mosquitoes that were coming to bite us so we could collect them to check if they were carrying malaria.
為此，我和同事來(lái)到跨過(guò)河30公里以外的ifakara鎮(zhèn)以南。每晚我們都帶著手電筒和虹吸管去村子里我們卷起褲管等著蚊子來(lái)叮咬我們因此，我們可以收集它們檢查它們是否攜帶瘧疾病毒。
my colleague and myself selected ahousehold, and we started inside and outside, swapping positions every half hour. and we did this for 12 hours every night for 24 consecutive nights. we slept for four hours every morning and worked the rest of the day, sorting mosquitoes, identifying them and chopping off their heads so they could be analyzed in the lab to check if they were carrying malaria parasites in their blood mouthparts. this way we were able to not only know how much malaria was going on here but also which mosquitoes were carrying this malaria. we were also able to know whether malaria was mostly inside houses or outside houses.
我和同事選了一戶人家然后我們開(kāi)始屋里屋外站崗，每隔半小時(shí)換一班，每晚值班12個(gè)小時(shí)，連續(xù)干了24個(gè)晚上。我們每天早上睡4個(gè)小時(shí)其余時(shí)間都一直工作我們將收集到的蚊子分類，辨認(rèn)它們并切下它們的頭這樣它們就可以被送到實(shí)驗(yàn)室里去分析了看它們帶血的口器里是否攜帶瘧原蟲。這樣，我們不僅知道有多少例瘧疾發(fā)生也知道是哪種蚊子攜帶瘧疾源我們還可以知道瘧疾是常在屋內(nèi)感染還是在屋外。
today, ladies and gentlemen, i still catch mosquitoes for a living. but i do this mostly to improve people's lives and well-being. this has been called by some people the most dangerous animal on earth -- which unfortunately is true. but what do we really know about mosquitoes? it turns out we actually know very little.
女士們，先生們，如今我還是靠捕蚊為生但主要是為了延長(zhǎng)人們的壽命，改善他們的生活。有些人說(shuō)，這是世界上最危險(xiǎn)的動(dòng)物不幸的事，事實(shí)確實(shí)如此但是我們又對(duì)蚊子了解多少呢?結(jié)果表明，我們對(duì)蚊子了解甚微。
consider the fact that at the moment our best practice against malaria are bednets -- insecticide treated bednets. we know now that across africa you have widespread resistance to insecticides. and these are the same insecticides, the pyrethroid class,that are put on these bednets. we know now that these bednets protect you from bites but only minimally kill the mosquitoes that they should. what it means is that we've got to do more to be able to get to zero. and that's part of our duty.
事實(shí)是我們現(xiàn)在對(duì)抗蚊子最實(shí)際的做法是蚊帳-涂有驅(qū)蚊劑的蚊帳我們得知，在整個(gè)非洲普遍存在殺蟲劑抵抗現(xiàn)象蚊帳用的就是這種殺蟲劑除蟲菊素類殺蟲劑，它們被用在蚊帳上我們現(xiàn)在知道，蚊帳能保護(hù)我們不受叮咬，但是殺蚊效果很差，不盡人意。這意味著，我們還要采取更多措施才能把蚊蟲消滅干凈。而這也是我們的職責(zé)。
at ifakara health institute we focus verymuch on the biology of the mosquito, and we try to do this so we can identify new opportunities. a new approach. new ways to try and get new options that we can use together with things such as bednets to be able to get to zero. and i'm going to share with you a few e_amples of the things that my colleagues and myself do.
在ifakara健康研究機(jī)構(gòu)我們主要研究蚊子的生物學(xué)特性以便尋找新的機(jī)會(huì)發(fā)現(xiàn)新的途徑新的方法，來(lái)尋找其他滅蚊方式與蚊帳等傳統(tǒng)手段結(jié)合一同將蚊子消滅干凈。我要給你看我和我同事做的新的東西。
take this, for e_ample. mosquitoes breed in small pools of water. not all of them are easy to find -- they can be scattered across villages, they can be as small as hoofprints. they can be behind yourhouse or far from your house. and so, if you wanted to control mosquito larvae,it can actually be quite difficult to get them. what my colleagues and i have decided to do is to think about what if we used mosquitoes themselves to carry the insecticides from a place of our choice to their own breeding habitats so that whichever eggs they lay there shall not survive.
比如說(shuō)這個(gè)，蚊子在小水洼里繁殖并不是所有的蚊子都容易發(fā)現(xiàn)有的散布在村子各處有的像蹄印一樣小有的就在你家后院，有的卻離你房子很遠(yuǎn)。因此要想控制住蚊子卵也是很困難的。我和我的同事決定要做的是想讓蚊子自己將殺蚊劑從我們指定的地點(diǎn)帶到它們繁殖的棲息地消滅那個(gè)地方所有的蚊卵。
this is dickson lwetoijera. this is my colleague who runs this show at ifakara. and he has demonstrated cleverly that you can actually get mosquitoes to come to the place where they normally come to get blood to pick up a dose of sterilants or insecticide, carry this back to their own breeding habitat and kill all their progeny. and we have demonstrated that you can do this and crush populations very, very rapidly. this is beautiful.
這是狄更斯·維托杰亞我的同事，在ifakara展示這一試驗(yàn)他聰明的驗(yàn)證了可以讓蚊子從它常去采血的地方采到帶有殺菌劑或者殺蟲劑的血液然后把它們帶到它們的繁殖地殺掉它們所有的蟲卵。并且，我們可以證實(shí)你可以做到并很快的減少蚊子的數(shù)量這太美了。
this is our mosquito city. it is the largest mosquito farm available in the world for malaria research. here we have large-scale self-sustaining colonies of malaria mosquitoes that we rear in these facilities. of course, they are disease-free. but what these systems allow usto do is to introduce new tools and test them immediately, very quickly, and see if we can crush these populations or control them in some way. and my colleagues have demonstrated that if you just put two or three positions where mosquitoes can go pick up these lethal substances, we can crush these coloniesin just three months. that's auto dissemination, as we call it.
這是我們的蚊子城市。這是全世界最大的蚊子養(yǎng)殖基地用于支持對(duì)瘧疾的研究。在這個(gè)基地里，我們養(yǎng)了一大批自給自足的瘧疾蚊子群體。當(dāng)然，它們是不攜帶任何疾病的這些系統(tǒng)使我們可以引進(jìn)新技術(shù)并立即投入試驗(yàn)非?？觳⒖纯次覀兪欠衲芟麥缥米臃N群或者設(shè)法控制它們我的同事也證明了只需在兩三個(gè)地方投放致命物質(zhì)讓蚊子去采集，我們就可以將蚊群在三個(gè)月內(nèi)消滅干凈。我們稱它為：自動(dòng)化播散。
but what if we could use the mosquitoes'se_ual behavior to also control them? so, first of all i would like to tell you that actually mosquitoes mate in what we call swarms. male mosquitoes usually congregate in clusters around the horizon, usually after sunset. the males go there for a dance, the females fly into that dance and select a male mosquito of their choice, usually the best-looking male in their view.
但是我們是否可以利用蚊子的性行為來(lái)控制它們?首先，我想跟你們說(shuō)的是蚊子其實(shí)是聚眾交配的，公蚊子通常成群結(jié)隊(duì)的聚集在地表面，太陽(yáng)落山后公蚊子去那里跳舞母蚊子也過(guò)去跳舞，并挑選一個(gè)她們看上的公蚊子，——通常是那個(gè)看起來(lái)最英俊的。
they clump together and fall down onto the floor. if you watch this, it's beautiful. it'sa fantastic phenomenon. this is where our mosquito-catching work gets really interesting. what we have seen, when we go swarm hunting in the villages, isthat these swarm locations tend to be at e_actly the same location every day,every week, every month, year in, year out. they start at e_actly the same time of the evening, and they are at e_actly the same locations.
它們聚集在一起，然后落到地上你要看到這景象，你也會(huì)認(rèn)為很美。這真是一個(gè)太棒的現(xiàn)象了這就是我們捕蚊工作的好玩之處當(dāng)我們到村里的沼澤去捕蚊子的時(shí)候會(huì)發(fā)現(xiàn)，這些沼澤地總是固定不動(dòng)的每天，每周，每個(gè)月年復(fù)一年。它們每晚都在相同的時(shí)間開(kāi)始交配，它們也去相同的地點(diǎn)。
what does this tell us? it means that if we can map all these locations across villages, we could actually crush these populations by just a single blow. kind of, you know,bomb-spray them or nuke them out. and that is what we try to do with young menand women across the villages. we organize these crews, teach them how to identify the swarms, and spray them out. my colleagues and i believe we have a new window to get mosquitoes out of the valley.
這給我們有什么啟發(fā)呢?這就意味著，如果我們可以在村子里找到這些地點(diǎn)我們就能把這些蚊子一網(wǎng)打盡。就像，用炸彈覆蓋或者核武器一樣消滅它們那就是我們和青年男女在村子里嘗試做的事我們把這幫人組織起來(lái)，教他們?nèi)绾稳ケ嬲J(rèn)蚊群并噴灑藥物殺死它們。我和我的同事相信我們有新的機(jī)會(huì)將蚊子趕出村子。
but perhaps the fact that mosquitoes eat blood, human blood, is the reason they are the most dangerous animal on earth.but think about it this way -- mosquitoes actually smell you. and they have developed incredible sensory organs. they can smell from as far sometimes as100 meters away. and when they get closer, they can even tell the difference between two family members.
但是事實(shí)是，這些蚊子吸血，吸人類的血這就是為什么他們是世上最危險(xiǎn)的動(dòng)物但是，請(qǐng)這樣想-蚊子實(shí)際上是聞到了你的氣味而它們進(jìn)化出了不可思議的感覺(jué)器官它們可以聞到100米開(kāi)外的氣味它們離你很近的時(shí)候連一家的兩個(gè)不同成員都能區(qū)分出來(lái)。
they know who you are based on what you produce from your breath, skin, sweat and body odor. what we have done at ifakara is to identify what it is in your skin, your body, your sweat or your breath that these mosquitoes like. once we identified these substances, we created aconcoction, kind of a mi_ture, a blend of synthetic substances that are reminiscent of what you produce from your body. and we made a synthetic blend that was attracting three to five times more mosquitoes than a human being.
它們通過(guò)你呼出的氣體，皮膚分泌物，汗液，體味就能知道你是誰(shuí)。我們?cè)趇fakara做的是去鑒別來(lái)自你皮膚，你身體，汗液和呼吸中那些蚊子喜歡的東西。一旦我們找到這種物質(zhì)，我們就可以做一種混合劑一種合成物質(zhì)接近人類的體味。我們做了一個(gè)合成的混合物它吸引蚊子數(shù)量是人類能夠吸引的3-5倍。
what can you do with this? you put in a trap, lure a lot of mosquitoes and you kill them, right? and of course, you can also use it for surveillance. atifakara we wish to e_pand our knowledge on the biology of the mosquito; to control many other diseases, including, of course, the malaria, but also those other diseases that mosquitoes transmit like dengue, chikungunya and zikavirus.
你可以用這個(gè)做什么?你埋下陷阱，吸引大批的蚊子，然后再殺死它們，對(duì)吧?當(dāng)然，它還可以起到監(jiān)視作用在ifakara我們希望可以拓展我們?cè)谖米拥纳飳W(xué)方面的知識(shí)去控制其它的疾病，當(dāng)然包括瘧疾在內(nèi)還有通過(guò)蚊子傳播的其他疾病諸如登革熱，奇昆古尼亞熱病和寨卡病毒。
and this is why my colleagues, for e_ample -- we have looked at the fact that some mosquitoes like to bite you on the leg region. and we've now created these mosquito repellent sandals that tourists and locals can wear when they'recoming. and you don't get bitten -- this gives you 'round the clock protection until the time you go under your bednet.
這也是為什么我的同事，比方說(shuō)我們發(fā)現(xiàn)某些蚊子喜歡叮你的大腿。我們?yōu)榇艘舶l(fā)明了驅(qū)蚊涼鞋保護(hù)游人和當(dāng)?shù)厝嗣庠馕孟x叮咬因?yàn)檫@會(huì)給你隨時(shí)隨地的保護(hù)直到你回到你的蚊帳里去。
my love-hate relationship with mosquitoes continues.
我與蚊子的愛(ài)恨情仇還在繼續(xù)。
and it's going to go a long way, i can see.but that's ok. who has set a goal of 2030 to eliminate malaria from 35countries. the african union has set a goal of 2030 to eliminate malaria from the continent. at ifakara we are firmly behind these goals. and we've put together a cohort of young scientists, male and female, who are champions, who are interested in coming together to make this vision come true. they do what they can to make it work. and we are supporting them. we are here to make sure that these dreams come true.
我也知道滅蚊之路仍然任重道遠(yuǎn)。但是，這也不錯(cuò)。世衛(wèi)組織定了一個(gè)目標(biāo)，在2030年消滅35個(gè)國(guó)家的瘧疾。非洲聯(lián)合國(guó)家也定了個(gè)目標(biāo)在2030年將消滅非洲大陸的瘧疾。在ifakara,我們緊隨目標(biāo)我們集合了一大批青年科學(xué)家男女都有他們是勝利者愿意聚集在一起實(shí)現(xiàn)目標(biāo)。他們盡其所能去實(shí)現(xiàn)目標(biāo)。而我們?cè)谥С炙麄?。我們?lái)到這就是為了使這個(gè)夢(mèng)想成真。
ladies and gentlemen, even if it doesn't happen in our lifetime, even if it doesn't happen before you and me go away, i believe that your child and my child shall inherit a world free of malaria transmitting mosquitoes and free of malaria. thank you very much, ladies and gentlemen.thank you.
女士們，先生們即便這一夢(mèng)想沒(méi)有在我們有生之年起作用我相信你的孩子，我的孩子、也會(huì)享受一個(gè)沒(méi)有傳播瘧疾的蚊子也沒(méi)有瘧疾的世界。女士們，先生們。非常感謝。
kelo kubu: ok, fredros. let's talk about crispr for a bit.
凱勒·庫(kù)巴：好的，費(fèi)蘭德我們來(lái)聊點(diǎn)兒crispr吧
it's taken the world by storm, it promises to do amazing things. what do you think of scientists using crispr to kill off mosquitoes?
這讓整個(gè)世界很是震撼它預(yù)示著能夠做很多不可思議的事情，你怎么看科學(xué)家用crispr消滅蚊子。
fredros okumu: to answer this question,let's start from what the problem is. first of all, we're talking about a disease that still kills -- according to the latest figures we have from who -- 429,000 people. most of these are african children. of course, we've made progress,there are countries that have achieved up to 50-60 percent reduction in malaria burden. but we still have to do more to get to zero. there is already proof of principle that gene-editing techniques, such as crispr, can be used effectively to transform mosquitoes so that either they do not transmit malaria -- we call this population alteration -- or that they no longer e_ist, population suppression. this is already proven in the lab.
費(fèi)蘭德：要回答這個(gè)問(wèn)題，我們就得先說(shuō)一下問(wèn)題的實(shí)質(zhì)首先，我們講的是一個(gè)可以致人死亡的疾病據(jù)世貿(mào)衛(wèi)生組織最新數(shù)字表明已有429,000人因此而死亡多數(shù)是非洲兒童當(dāng)然，我們還是有成效的有些國(guó)家已經(jīng)減少了50-60%的瘧疾死亡率但是要達(dá)到零死亡，還需要時(shí)間已經(jīng)有證據(jù)表明基因編輯技術(shù)，比如crispr可以有效的用來(lái)改造蚊子，是他們不再傳播瘧疾我們稱它為人口替換抑或是他們根本就不復(fù)存在了蚊子數(shù)量驟減這些已經(jīng)通過(guò)實(shí)驗(yàn)證實(shí)了。
there is also modeling work that has demonstrated that even if you were to release just a small number of these genetically modified mosquitoes, that you can actually achieve eliminationvery, very quickly. so, crispr and tools like this offer us some real opportunities -- real-life opportunities to have high-impact interventions that we can use in addition to what we have now to eventually go to zero. this is important.now, of course people always ask us -- which is a common question, i guess you're going to ask this as well -- 'what happens if you eliminate mosquitoes?'
有一個(gè)樣板課題已經(jīng)證明了即使你去釋放少量這種經(jīng)基因改造后的蚊子就可以讓你快速將蚊子消滅光。因此，crispr和類似的工具提供給我們真正的機(jī)會(huì)-存在于現(xiàn)實(shí)生活中的高效能干擾機(jī)會(huì)可以供我們使用來(lái)增強(qiáng)我們現(xiàn)在所有的直到最后直到完全消滅這很重要現(xiàn)在，當(dāng)然很多人都在問(wèn)我們這也是一個(gè)很普遍的問(wèn)題我猜想你也會(huì)這樣問(wèn)“你們把所有的蚊子都消滅了又怎樣?”
kk: i won't ask then, you answer.
凱：那我就不問(wèn)了，你回答吧
fo: ok. in respect to this, i would just like to remind my colleagues that we have 3,500 mosquito species in this world.maybe more than that. about 400 of these are anophelenes, and only about 70 of them have any capacity to transmit malaria. in africa, we're having to deal with three or four of these as the major guys. they carry most -- like 99 percent of all the malaria we have. if we were to go out with gene editing like crispr, if we were to go out with gene drives to control malaria, we would be going after only one or two.
費(fèi)蘭德：好的，鑒于這問(wèn)題，我需要提醒我的同事告訴他們，在這世上有3500種蚊子或許比這還多。這其中400種是按蚊它們當(dāng)中的70是有能力傳播瘧疾的。在非洲我們要去處理大概3到4個(gè)這種大家伙它們能夠攜帶我們所擁有的99%的瘧疾。如果我們要利用像crispr基因改造系統(tǒng)，如果我們要利用基因去控制瘧疾，我們就只需要控制一兩種。
i don't see a diversity problem with that. but that's personal view. i think it's ok. and remember, by the way, all these years we've been trying to eliminate these mosquitoes effectively by sprayingthem -- our colleagues in america have sprayed with -- really bomb-spraying these insects out of the villages. in africa we do a lot of house hold spraying.all these are aimed solely at killing the mosquitoes. so there's really noproblem if we had a new tool.
我不認(rèn)為這有什么多元化的問(wèn)題。但是那僅是我的觀點(diǎn)我認(rèn)為這很好要記住，還有，在這些年來(lái)我們一直在嘗試去有效率的通過(guò)噴霧來(lái)消滅它們-我在美國(guó)的同事用炸彈噴霧工具來(lái)消滅將整個(gè)村子里的蟲子在非洲，我們用了很多家用噴蚊子的方法所有這些都僅僅只能夠殺滅蚊子因此我們?cè)侔l(fā)明個(gè)新工具也是沒(méi)問(wèn)題的。
but having said that, i have to say we also have to be very, very responsible here. so there's the regulatory side, and we have to partner with our regulators and make sure that everything that we do is done correctly, is done responsibly and that we also have to do independ entrisk assessments, to just make sure that all these processes do not fall into the wrong hands. thank you very much.
雖然我那樣說(shuō)，但是我還是不得不說(shuō)我也該越來(lái)越負(fù)責(zé)的說(shuō)但是，我們也有監(jiān)管的，我們要與我們的監(jiān)管人合作要確保我們做的所有事都正確，都做的很負(fù)責(zé)任我們還要去做獨(dú)立的風(fēng)險(xiǎn)測(cè)定僅僅為了確保整個(gè)過(guò)程萬(wàn)無(wú)一失。十分感謝
kk: thank you.(applause)
謝謝(掌聲)
