有人在雅思写作中文如泉涌，有人则是无话可说，出现这两种情况除了自己的写作基本之外，备考过程也是不容忽视的。用心准备的人，一定不会出现无话可说的情形，所以考生们平时对雅思写作素材的积累是很有必要的。下面津桥小编就为大家整理了雅思写作素材之能源环保话题，希望考生们有所借鉴。
能源与环保类话题是社会类大作文中的一个常考话题，主要考察环境保护、资源能源利用等内容，比如今年到目前为止考过两道，分别是：
20130907Nuclear energy is the best source of power in meeting ever-increasing energy needs. To what extent do you agree or disagree.
20130928Some people think they have right to use as much fresh water as they want，others otherwise believes governments should strictly control the use of fresh water as it is limited resource. Discuss both views and give your own opinion.
这两道题目分别考察了核能与水资源，历史上雅思作文还考过化石能源(fossil fuels)、保护环境、垃圾处理等问题。对于这类话题，同学总觉得有话可说，但是这话总也说的不够好，所以我们今天就一起来学习一下有哪些地道生动的表达。
1、I will direct my cabinet to come up with executive actions we can take, now and in the future, to reduce pollution, prepare our communities for the consequences of climate change, and speed the transition to more sustainable sources of energy.
Consequence:结果，后果，可以替换大家常用的result等词
speed the transition to more sustainable sources of energy：加速可替代能源的转化速度。Sustainable:可持续的
2、Their selection suggests that Mr Obama is indeed serious about tackling climate change, but not doctrinaire in his approach.
Tackle:处理，解决，相当于address, deal with, cope with,等词。
Doctrinaire: adj.空谈理论的，脱离实际的
3、Ms McCarthy already works at the EPA, where she is in charge of air quality. That has given her a leading role drafting the administration’s most ambitious and controversial environmental rules, including limits on emissions of greenhouse gases for new power plants and strict fuel-efficiency requirements for cars. She is the natural candidate to oversee the most obvious and consequential step Mr Obama could take to stem global warming: a regulation curbing emissions from existing power plants.
Ambitious:1有野心的2 费力的，耗时的，很多同学都知道这个词的第一个意思，但是很少有人知道它的第二个意思，这就是常用单词的不常见用法。
Controversial:争论的
limits on emissions of greenhouse gases：限制温室气体的排放，这几个词都非常常用，一定要学会。
power plants：发电厂
strict fuel-efficiency requirements：严格的能耗效率要求
consequential：1 随之而来的 2 重要的，将产生重大结果的。第二个用法非常好。
Stem: n. 茎;v. 阻止，遏制。动词的用法很好，可以用来替换prevent.
Curb:vt. 一直，限定(不好的事物)，可以跟上面的stem做替换。
4、Republicans do not like that idea at all, and have introduced bills in Congress to strip the EPA of its regulatory authority over greenhouse gases. (They also have no intention of passing any measures of their own to fight climate change.) They often accused Lisa Jackson, the agency’s previous boss, of disregarding the cumulative impact of its many clean-air rules, and suffocating industry as a result.
Strip sb. of sth.剥夺某人某事
disregarding the cumulative impact of：忽视。。。的累积影响。
Suffocating：令人呼吸困难的，压制作用的。
5、He shares the president’s enthusiasm for renewable power and other nascent green technologies, but he has also spoken in favour of building more nuclear reactors and of natural gas as “a bridge” to a low-carbon future.
Renewable:可再生的
in favour of：支持
low-carbon：低碳的
6、 However, the new output will benefit America, both by creating jobs and by bringing down energy bills as cheap gas replaces coal and oil. Lower prices will temper the ambitions of Russia, which lives on its oil and gas revenues. And if the world should fall to pieces, American supplies will be guaranteed.
Temper:n.脾气v.是缓和
最后一句话是虚拟条件句
7、American taxpayers are just subsidising Chinese consumers, they say. But ensuring free navigation has always been an essential feature of American primacy. Abandoning it might encourage China and India to build ocean-going navies to vie with America’s.
Taxpayer:纳税人，政府类话题常用词
Subsidise:给。。。补助
Primacy：首要，至高无上
Vie:激烈竞争 vie with sb. for sth.
