1、 你校将举办英语演讲比赛，请你以 Please Protect Our LivingEnvironment 为题写一篇发言稿参赛。内容包括:（1)你身边的环境问题; (2）相应的解决办法。注意:1.词数80左右;2.可适当增加细节,以使行文连贯。Please Protect Our Living Environment With the rapid development of the economy, air pollution in our area has become one of the most serious problems nowadays.Sometimes we have

2、 to wear masks.In order to protect our living environment,we must take necessary measures. First, go to school on foot or by bike instead of taking the car. Second, somefactories which release waste gases should be closed or moved out of the city. Inaddition,we must plant more and more trees. Only i

3、n this way can we breathe fresh air freely and live a happy life. In conclusion, we should advocate and live a low-carbon lifestyle. 请保护我们的生活环境 随着经济的快速发展，我们地区的空气污染已经成为当今最严重的问题之一。 有时我们不得不戴上面具。 为了保护我们的生存环境，我们必须采取必要的措施。 首先，步行或骑自行车上学，而不是坐汽车。 其次,一些排放废气的工厂应该关闭或迁出城市。此外，我们必须种植越来越多的树。 只有这样，我们才能自由呼吸新鲜空气，过上幸福的

4、生活。 总之，我们应该提倡低碳生活方式。 你校英语报刊人物专栏正在征稿,请你用英语介绍一位你所敬佩的在逆境中成长的人物并投稿。 要点如下: 1.对该人物的简单介绍; 2.敬佩该人物的理由; 3.从该人物身上得到的启示。 注意:词数80左右。 Every time I read Three Days to See,I cannot help being moved by its author Helen Keller. l admire Helen because she was optimistic about life.

There is little doubt that Earth is getting warmer and warmer (see the gr

10、aph). A warming ocean and atmosphere along with melting ice and rising sea levels provide evidence of a dramatic change in the global climate. 我们了解气候变化已经有几十年了。毫无疑问，地球是在变得越来越暖(见表)。海洋和气候变暖以及冰的融化和海平面的上升为全球气候的剧烈变化提供了证据。 In 2013, a lot of people were shocked by a news photo of a dead polar bear that was

11、found on Norways Arctic island of Svalbard. According to the scientists who found its dead body, all that remained of the polar bear was skin and bones . An expert who has studied polar bears for many years said that from the position of its dead body, the bear appeared to have starved and died. Exp

12、erts claimed that low sea-ice levels meant that the bear could not hunt seals as before, so it had to travel greater distances in order to find food. This alarming case showed how the increase in temperature had an impact on Earths ecology. 2013年，一张关于那威北极岛的斯瓦尔巴群岛上发现一只北极熊死亡的新闻照片，震惊了很多人。根据发现北极熊尸体的科学家的

13、说法，北极熊只剩下“皮肤和骨头”。一位研究北极熊多年的专家说，从北极熊尸体的位置看，北极熊似乎饿死了。专家声称，由于气候变化导致海冰面积下降，这只熊无法像以前那样捕猎海豹，因此它不得不走很远的距离才能找到食物。这个令人震惊的案例表明，温度升高如何影响地球的生态。分析句子成分have an impact on这会对全球经济和金融市场造成影响。这会对全球经济和金融市场造成影响。 Society begins to have an impact on the developing child. 社会开始对成长中的孩子产生影响。社会开始对成长中的孩子产生影响。 And that would have

15、e surface temperature? Climate scientists often mention a key climate process called the greenhouse effect which has two common meanings: the natural greenhouse effect and the man-made greenhouse effect. The natural greenhouse effect refers to the fact The heat is released back into space at longer

16、wave lengths. Greenhouse gases in the atmosphere, such as methane and carbon dioxide, trap some of the heat, keeping Earths climate warm and habitable. Without this process, Earth could not sustain life. However, the man-made greenhouse effect has now become a big problem. When people produce huge a

17、mounts of extra greenhouse gases by burning fossil fuels, more heat energy is trapped in the atmosphere and causes Earths surface temperature to rise quickly. 那么，是什么导致全球平均表面温度上升?气候科学家经常提到一个称为“温室效应”的重要气候过程，它有两个普遍的含义：“自然”温室效应和“人造”温室效应。“自然”温室效应是指太阳的热量进入大气层，并以短波辐射的形式使地球表面变暖。热量以更长的波长释放回太空。大气层中的温室气体(如甲烷和二

18、氧化碳)吸收了部分热量，使地球的气候温暖宜居。没有这个过程，地球将无法维持生命。然而，“人造”温室效应现在已成为一个大问题。当人们燃烧化石燃料产生大量额外的温室气体时，更多的热量被困在大气层中，从而引起地球表面温度迅速上升。 There is strong and comprehensive evidence that the rise in temperature has led to an increase in extreme weather and natural disasters worldwide, not only causing serious damage, but als

19、o costing human lives. Climate scientists have warned take appropriate actionsa higher price In fact, news reports are frequently broadcast about extreme rainstorms and heatwaves causing deaths and economic losses. 有充分而全面的证据表明，温度升高导致全世界范围内极端天气和自然灾害增加，不仅造成了严重的破坏，而且还造成了人员伤亡。气候科学家警告说，如果我们不采取适当的行动，这种变暖趋

20、势可能会持续下去，并且需要付出更高的代价。事实上，新闻报道经常播出极端暴雨和热浪造成死亡和经济损失。 Continued greenhouse gas emissions will result in further warming and long-lasting changes to the global climate. This requires the attention of people all over the world. Governments need to consider making policies and taking appropriate actions a

21、nd measures to reduce greenhouse gas emissions. We as individuals can also reduce our carbon footprint by restricting the amount of carbon dioxide our lifestyles produce. It is our responsibility to seize every opportunity to educate everyone about global warming, along with its causes and impacts,

22、because this is the most serious issue affecting all of us on this planet. So what will you do to help? 持续的温室气体排放将导致全球气候进一步变暖和持久变化。这需要全世界人民的关注。政府需要考虑制定政策，采取适当的行动和措施以减少温室气体排放。我们个人也可以通过限制生活方式产生的二氧化碳量来减少“碳足迹”。抓住每一个机会，对所有人进行全球变暖及其成因和影响的教育，这是我们的责任，因为这是影响我们地球上所有人最严重的问题。那你会怎么做?1. starve2. ecology3. release

25、dtrendsare starving1 We use a lot of energy in our houses. It is OK to leave an electrical appliance on so long as you are using it - if not, turn it off! Do not be casual about this. So if you are not using the lights, the TV, the computer, and so on, turn them off. If you are cold, put on more clo

26、thes instead of turning up the heat.2 Motor vehicles use a lot of energy- so walk or ride a bike if you can.3 Recycle cans, bottles, plastic bags and newspapers if circumstances allow you to. It takes a lot of energy to make things from new materials, so, if you can, buy things made from recycled ma

27、terials.4 Get your parents to buy things that are economical with energy - this includes cars as well as smaller things like fridges and microwaves.5 Plant trees in your garden or your school yard, as they absorb carbon dioxide from the air and refresh your spirit when you look at them.6 Finally and most importantly, be an educator. Talk with your family and friends about global warming and tell them what you have learned.Remember - your contribution counts!
