we all know tagore.this famous indian poet once said, “life is given to us, and we earn it by giving it.” as the saying goes, nature is given to us, and we earn it by contributing to it. however, most people nowadays just want to ask for more from the nature. in fact, they do very little contribution to the nature. therefore, the environment around us is becoming worse and worse. do you often use batteries? then do you know it takes 50 times more energy to make them than they produce? andjust one simple battery can pollute as much water as a person can drink in his whole life. the facts and figures are amazing. so would you please try to use batteries only when it is necessary? if possible, give the used ones to the recycling companies so that they will be made into new ones and won’t be able to pollute the environment any more. sometimes we become complacent when it comes to recycling, but when you speak in terms of actual facts and figures that everybody can understand, people become much clearer about the problem. we, as school students, can also join in recycling activities to protect the environment. for example, our class set up a recycling center beside the back door, it is very useful. it is used to collect the waste paper and plastic bottles. in the past, our classmates used to throw all of these into the trashcan. at the very beginning of this collecting activity, it was not so warm-welcomed. later, more and more people were influenced by the others and joined this collecting activity. gradually, all the students in our class form a good habit to protect the environment. all of us will now put away the reusable things instead of throwing them into the trashcan.
we should always remember in our mind that protecting the environment is our duty that we can never neglect. finally would you please let me end this speech with a little poem, “be kind to the river. be good to the trees. smile at the sunshine, and bow to the breeze. be friendly to nature, and nature will be friendly to you!”

stepping into the new century environment pollution has become more serious than ever since. there are different kinds of pollution. such as water pollution air pollution and noise pollution and so on. it seems that we live on a planet which is full of pollution. where all these pollution comes from? to a large extend the environmental destruction is the heavy price that we pay for the rapid development of economy and the growing population. in order to have more fuel people cut down trees and dig more corals. but the growing needs for energy are hardly to meet. countless private cars on the street the gas stations are short of gasoline even the government has raise the price so many times in order to control the needs of gasoline but it’s still not working. overusing the natural resources has already affected the ecological balance. however the factories still release the toxic air into the sky and the polluted water into the rivers. people still lack of the conscious of protecting the environment. i think it’s time for all of us to do something. the government should put forward some more strict laws to prevent the environment from being further polluted. and they should let people know more about the importance of environment protection. and we should find the balance between the economic growth and environmental protection. plant more trees in the deserts and stop cutting down the forest. forbid the factories to pour the waste water into the rivers directly. encourage people to use public transportations to work. both government and ordinary people should join hands together to make our home clean and fresh again. only in this way our earth could be a better place to live in.

demand for graduates in the uk with skills related to sustainability is booming. academia is waking up to the need to train specialists in green architecture, chemistry and engineering.
dean millar founded the world’s first ever bsc course in renewable energy at exeter university after working as an industry consultant.
he said： “a lot of companies were complaining that there was a lack of bright young people suitably trained to work in the renewables business.”
now his course has around 90 students learning the ins and outs of biomass, tidal, solar and offshore wind power.
their career prospects are incredibly bright. employment opportunities are not just limited to the energy sector, but segue into the regulatory and, increasingly, investment sectors as well.
“the big boys are moving in. the returns to be had are significant, especially in terms of wind development,” said millar. “financial firms need expertise across the board so they can make sensible investment decisions.”
students on york university’s master’s course in green chemistry are ideally placed to take advantage of the growing demand in industry for graduates with waste minimization skills.
professor james clark is founder of york’s green chemistry centre for excellence and the world’s leading green chemistry journal, green chemistry. he said： “we are now talking to producers of automobiles, electronics, furniture and pharmaceuticals, people who need to use chemistry but don’t think of themselves as chemists.”
as waste production legislation becomes increasingly strict, the traditional emphasis on making as much of a chemical as possible is shifting towards minimizing the waste that process creates. “a lot of chemicals are made from petroleum, but we are developing sustainable ways to make carbon, typically from biomass such as dead plants and trees,” said professor clark.
all of last year’s graduates quickly found employment, some receiving multiple job offers in a variety of different fields.
li li, a 26-year-old chinese postgraduate student, graduated from york in 20xx. she said：
“i hadn’t heard about green chemistry in china. it was a new area and i was curious. now the government back home needs people who know about these principles.”
deep in the heart of wales, 400 students at the centre for alternative technology’s （cat） graduate school of the environment are busy designing and building everything from high insulation wood housing to wind power turbines. with energy costs rising, building firms are increasingly looking to minimize the energy wasted heating and lighting homes, a service cat students are well-equipped to provide.
a new institute is being built to meet the burgeoning demand for places and a distance learning facility will be launched next september so foreign students can complete cat courses from home.
the expertise being taught on these courses is essential to a continually expanding range of companies and government authorities. yet there is a larger goal at stake； the students are at the forefront of the battle against climate change. in the words of dean millar, “if we’re going to save the planet, we need to start turning these people out in big numbers.”

what is nature？ it＇s everything that exists in the world independently of people, such as pants and animals, earth and rocks, and the weather.
now more and more people are focusing on the nature. it is no doubt that the nature is important to every human being. no nature, no life. because of the supplies of the nature, we have lived happily for a long time. and we started to gain every thing available from the nature. and this lasted so long a time. today, people have discovered that the nature around is getting worse and worse.
what is threatening the nature？ air and water pollution, overharvesting of plant and animal species, overpopulation and so on. overpopulation is the biggest source of pollution. let＇s take overpopulation as an example.
what does overpopulation feel like？ when we move slowly through the city in a tazi. when we enter a crowded slum district. when the temperature is high and when the air is thick with dust and smoke. the streets are crowded with people. the streets seem alive with people. people eating. people washing. people talking. people sleeping. people visiting each other, arguing and screaming. people relieving themselves. people pushing their hands through the taxi windows, begging. people leading animals. people, people, people, people. as we drive slowly through the crowd, sounding the taxi＇s horn, the dust, heat, noise and cooking fires made it like a scene from hell! i admit, frightening.
to the nature, overpopulation is a big problem. more people, more pollution. and the big population is threatening the nature every second.
the rapid rise in world population is not creating problems only for the developing countries. the whole world faces the problem that raw materials are being used up at an increasing rate and food production can not keep up with the population increase. people in rich countries make the heaviest demands on the world＇s resources, its food, fuel and land, and cause the most pollution. a baby born in the united states will use in his lifetime 30 times more of the world＇s resources than a baby born in india. unless all the countries of the world take united action to deal with the population explosion there will be more and more people fighting for a share of less and less land, food and fuel, and the future will bring poverty, misery and war to us all.
for most of the developing countries, it is a good idea to control the population growth. for example, china has carried out birth control for years. and this plan has a great effect on the world population.
if the population continues to increase, if the air and water continue to be polluted, if we don＇t do something to protect wild-plant and wildlife species will be declining. species and biological communities have difficulty adapting to change. economic opportunities and the quality of life of future generations are also put at risk. by protecting nature, we protect ourselves.
let＇s unite together, hand in hand we stand all across the land.
we can make this world in which to live. hand in hand. control the population growth. take good care of our nature.
英语主题演讲稿篇5
“dear mr. president:
“i realize that it is difficult to communicate meaningfully across the gulf of four years of war. but precisely because of this gulf i wanted to take this opportunity to reaffirm in all solemnity my desire to work for a just peace. i deeply believe that the war in vietnam has gone on too long and delay in bringing it to an end can benefit no one, least of all the people of vietnam. the time has come to move forward at the conference table toward an early resolution of this tragic war. you will find us forthcoming and open-minded in a common effort to bring the blessings of peace to the brave people of vietnam. let history record that at this critical juncture both sides turned their face towards peace rather than toward conflict and war."
death. it simply reiterated the public position north vietnam had taken at paris and flatly rejected my initiative. the full text of both letters is being released to the press.
in addition to the public meetings that i’ve referred to, ambassador lodge has met with vietnam’s chief negotiator in paris in 11 private sessions.
and we have taken other significant initiatives which must remain secret to keep open some channels of communications which may still prove to be productive.
but the effect of all the public, private and secret negotiations which have been undertaken since the bombing halt a year ago, and since this administration came into office on jan. 20, can be summed up in one sentence: no progress whatever has been made except agreement on the shape of the bargaining table.
well, now, who’s at fault? it’s becoming clear that the obstacle in negotiating an end to the war is not the president of the united states. it is not the south vietnamese government. the obstacle is the other side’s absolute refusal to show the least willingness to join us in seeking a just peace.
and it will not do so while it is convinced that all it has to do is to wait for our next concession, and our next concession after that one, until it gets everything it wants.
there can now be no longer any question that progress in negotiation depends only on hanoi ’s deciding to negotiate -- to negotiate seriously.
i realize that this report on our efforts on the diplomatic front is discouraging to the american people, but the american people are entitled to know the truth -- the bad news as well as the good news -- where the lives of our young men are involved.
now let me turn, however, to a more encouraging report on another front. at the time we launched our search for peace, i recognized we might not succeed in bringing an end to the war through negotiations. i therefore put into effect another plan to bring peace -- a plan which will bring the war to an end regardless of what happens on the negotiating front.
it is in line with the major shift in u. s. foreign policy which i described in my press conference at guam on july 25.
let me briefly explain what has been described as the nixon doctrine -- a policy which not only will help end the war in vietnam but which is an essential element of our program to prevent future vietnams.
we americans are a do-it-yourself people -- we’re an impatient people. instead of teaching someone else to do a job, we like to do it ourselves. and this trait has been carried over into our foreign policy.
in korea, and again in vietnam, the united states furnished most of the money, most of the armament and most of the men to help the people of those countries defend their freedom against communist aggressions.
before any american troops were committed to vietnam, a leader of another asian country expressed this opinion to me when i was traveling in asia as a private citizen.
he said: “when you are trying to assist another nation defend its freedom, united states policy should be to help them fight the war, but not to fight the war for them.”
well in accordance with this wise counsel, i laid down in guam three principles of guidelines for future american policy toward asia .
first, the united states will deep all of its treaty commitments.
second, we shall provide a shield if a nuclear power threatens the freedom of a nation allied with us, or of a nation whose survival we consider vital to our security.
third, in cases involving other types of aggression we shall furnish military and economic assistance when requested in accordance with our treaty commitments. but we shall look to the nation directly threatened to assume the primary responsibility of providing the manpower for its defense.
i pledge to you tonight that i shall meet this responsibility with all of the strength and wisdom i can command, in accordance with your hopes, mindful of your concerns, sustained by your prayers.
thank you.

transpositonal considerationgood afternoon, ladies and gentleman. thanks for raising your attention. taday, i’ll give you a speech entitled“transpositonal consideration”.
before starting my speech i would like to ask you a question! have you heard the saying that what we cannot afford to lose is nothing but innovation. yes, i have. i’ve always believed it is a truth.
i have heard that three apples changed the world. the first one seduced eve. the second one awakened newton. the third one was in the hands of steve jobs. we sort of think the innovation of the world began with apple.i imagine lots of people want to become another newton or jobs right now with just one hand to change the world, right? have the innovation to follow your heart. it somehow already reflects what you truly want to become. everything else is secondary.
via question, we can start to innovate. via innovating, we can start to create better life. no innovation, no improvement. no improvement, no success. and no success, no civilization.and the key to succssful innovation is always to be persistant we try to innovate, maybe we would feel helpless, puzzled, and sad.
however, this is what we must experience. don't let yourself down! it is innovation that we cannot afford to lose! that’s all, thank you!
