急!帮忙英语作文!.谢谢
题目是climate change!
讲的是“温室效应”(global warming)
有些人说 这样下去 温室效应会越来越严重!有些人说 温室效应会消失的!
你的观点是什么?
要一篇 不少于200字的英语作文.谢谢啦!.
呃,不是这样的! 我要的是 “观点essay”, (你的观点是.?) 不是来解释.
什么是温室效应?有什么危害?
温室有两个特点:温度较室外高,不散热. 生活中我们可以见到的玻璃育花房和蔬菜大棚就是典型的温室.使用玻璃或透明塑料薄膜来做温室,是让太阳光能够直接照射进温室,加热室内空气,而玻璃或透明塑料薄膜又可以不让室内的热空气向外散发,使室内的温度保持高于外界的状态,以提供有利于植物快速生长的条件.
由环境污染引起的温室效应是指地球表面变热的现象.
它会带来以下列几种严重恶果:
1) 地球上的病虫害增加;
2) 海平面上升;
3) 气候反常,海洋风暴增多;
4) 土地干旱,沙漠化面积增大.
科学家预测:如果地球表面温度的升高按现在的速度继续发展,到2050年全球温度将上升2-4摄氏度,南北极地冰山将大幅度融化,导致海平面大大上升,一些岛屿国家和沿海城市将淹于水中,其中包括几个著名的国际大城市:纽约,上海,东京和悉尼.
温室效应是怎么来的?我们能做什么?
温室效应主要是由于现代化工业社会过多燃烧煤炭、石油和天然气,这些燃料燃烧后放出大量的二氧化碳气体进入大气造成的.
二氧化碳气体具有吸热和隔热的功能.它在大气中增多的结果是形成一种无形的玻璃罩,使太阳辐射到地球上的热量无法向外层空间发散,其结果是地球表面变热起来.因此,二氧化碳也被称为温室气体.
人类活动和大自然还排放其他温室气体,它们是:氯氟烃(CFC〕、甲烷、低空臭氧、和氮氧化物气体、地球上可以吸收大量二氧化碳的是海洋中的浮游生物和陆地上的森林,尤其是热带雨林.
为减少大气中过多的二氧化碳,一方面需要人们尽量节约用电(因为发电烧煤〕,少开汽车.另一方面保护好森林和海洋,比如不乱砍滥伐森林,不让海洋受到污染以保护浮游生物的生存.我们还可以通过植树造林,减少使用一次性方便木筷,节约纸张(造纸用木材〕,不践踏草坪等等行动来保护绿色植物,使它们多吸收二氧化碳来帮助减缓温室效应.

What is the greenhouse effect? What harm?
Two characteristics: greenhouse temperature is high, no heat, outdoor. We can meet in life of glass (a greenhouse and vegetable is typical of greenhouse. Use transparent glass or plastic greenhouse, is to allow sunlight to direct illuminate, heating indoor air into the greenhouse, transparent glass or plastic film and can not make indoor air outside sends out, make indoor temperature remains above the state, in order to provide outside for plant growth conditions.
The environmental pollution caused by greenhouse refers to the heat of the earth's surface.
It will bring to the following several serious consequences:
1) on the earth; the pest
2) rising seas,
3) ocean storms abnormal weather, increase,
4) land desertification and drought is increasing.
Scientists predict: if the earth's surface temperature at its present rate, by 2050 to continue the development of global temperatures will rise by 2-4 degrees Celsius, south polar ice melts in rising greatly, will rise greatly, some islands and coastal cities will be flooded in water, including several famous international cities: New York, Shanghai, Tokyo and Sydney.
What is the greenhouse effect? What can we do?
The greenhouse effect is mainly due to the modern industrial society overmuch burning coal, oil and gas, the fuel burning after release large amounts of carbon dioxide into the atmosphere.
Carbon dioxide gas, heat insulation and heat with the function. It is in the atmosphere is formed a kind of aeriform glass, make the sun radiate to heat the earth can spread from outer space, the result is the earth's surface heat up. Therefore, also called the greenhouse gas carbon dioxide.
Human activities and nature also emissions of greenhouse gases and other, they are: LvFuTing (CFC), methane, low nitrogen gas, ozone and on earth can absorb carbon dioxide is a Marine plankton and continental forests, especially tropical rainforest.
To reduce the atmosphere of carbon dioxide, on the one hand, need much people try to save electricity (because power, less coal burning car. On the other hand to protect forests and sea, for instance, don't let not overcutting forest to protect Marine pollution of plankton. We can also through afforestation, reduce the use of disposable wooden chopsticks, convenient save paper, wood pulp (with no trample on the lawn, action to protect the green plant, make them more carbon dioxide to help alleviate the greenhouse effect.
