  环境问题越来越多地出现在高考英语的书面表达题中,比如2010年高考英语福建卷书面表达题的主题即为“水资源短缺”。要写好关于环境的话题作文,在平时的写作训练中,可以注意以下两方面的积累。
  一、了解环境问题的热点话题
  各类媒体都有不少对环境问题的报道,多听多看这些报道,记录热点话题,既能积累写作材料,又能熟悉一些专有名词和固定搭配,比如:world population explosion世界人口爆炸,preserve natural resources保护自然资源,water pollution and air pollution水污染和空气污染,energy-saving society节约型社会,climate change气候变化,environment protection环境保护,global shortage of water全球水资源短缺,等等。
  二、了解环境问题话题作文的体裁,积累写作内容
  一般来说,有关环境的话题作文多为议论文,写作时可采用“三步式”搭建文章结构:首先,提出问题或危害;其次,分析问题产生的原因;最后,阐述个人的观点或解决方法。
  下面就让我们看看在“三步式”的结构中,具体有哪些内容可以写作。
  (1) 环境问题的表现和危害
  气候变暖:The global climate is becoming warmer and warmer. It makes the ice melt, which causes coastal cities to be flooded.
  水资源污染:The waste from chemical factories makes rivers and lakes dirty, and the amount of water that is suitable for us to drink is becoming scarcer.
  酸雨现象:Chemicals in the smoke from power stations travel hundreds of miles in the wind before falling to the ground in the rain. The “chemical rain” gradually destroys trees and buildings.
  绿化减少:In the city, the grassland is replaced by tall buildings. In the wild, the wasteland takes the place of green forests.
  野生动物濒临灭绝:Nowadays, many wild animals have no place to survive, and they are facing the danger of extinction.
  (2) 产生原因
  资源消耗:With the increasing world population,people need more resources and energy such as food, space, water, coal, oil and so on. Some of them are limited or non-renewable.
  乱排乱放:Factories along the river always pour their waste water and rubbish straight into the river, which causes water pollution. Factories, power stations and cars in the city give off huge amounts of waste gas into the air, leading to air pollution.
  滥砍滥伐:People cut down trees freely to increase the output of disposable tableware and paper napkins.
  滥捕滥杀:People kill wild animals just for their fur, meat or teeth.
  (3) 解决方法
  从政府角度看:
  Make stricter laws to protect the environment.
  Close the factories which give off too much pollution or consume too much energy.
  Strengthen efforts to promote the awareness of environmental protection.
  从个人角度看:
  We should live a low-carbon life.
  When we go out, it’s best to ride a bike or take a bus.
  Remember to turn off the lights when we leave the classroom and turn off the tap when we’re not using it.
  Cut use ofdisposable tableware as much as we can.
  Try to use a handkerchief instead ofpaper napkins.
  In our free time, collect empty bottles and waste paper for recycling.
  现在,假设你本月底将前往澳大利亚参加主题为“Water for Life”的高中生交流活动,那么根据下图提示和以上语言积累,写一篇发言稿应该不是太困难的事情了。
  
  写作时,文章格式首先要符合发言稿的形式,开头要向观众作自我介绍并说明演讲主题: Ladies and gentlemen, Good morning. I’m ××× from China. It’s my great honor to be here to say something about global water shortage;结尾要有致谢词:Thank you for listening。然后根据图片提示选择合适的内容进行表达,可以先提出水资源短缺这一问题,并分析原因:The amount of water that is suitable for us to drink is becoming scarcer. As the world population increases,people need more resources, including water, but the waste from chemical factories makes rivers and lakes dirty;然后表达观点:People can’t live without water, we should take measures to reserve water;最后提出解决水资源短缺的办法:Scientists are developing new technology to turn sea water into fresh water. The government should make stricter laws to protect water resources and close the factories which give off too much waste into rivers and lakes. Meanwhile, we should not waste water. For example, turn offthe tap when we’re not using it。用一些恰当的过渡词、过渡句将以上内容连贯起来,发言稿就完成了。

近几年,社会舆论时有批评中学生习作内容空洞无物的声音。这也难怪,高考阅卷时,就经常可见内容单薄的文章,主要表现在:(1) 空泛,没有具体内容,更没有具体细节;(2) 单调,材料少得可怜又不具体,不能充分论证观点或表现人物;(3) 陈旧,材料虽多但全是老面孔;(4) 雷同,材料虽多但在同一层次上或论证角度单一,几个材料只能发挥一个材料的作用。这样的文章往往只能得个及格分,如果文章还涉嫌离题或者书写潦

在导数的定义f′(x)=中,我们第一次接触了这一符号,也是教材中第一次正式提出“limit”,即“极限”的概念.极限是高等数学微积分中最基本、最主要的核心概念之一,而在中学数学中,也有很多重要的概念、方法与极限有关,其“逼近”的思想渗透了数学的每一个角落.  (1) 数集:数集中定义的无限集,如自然数集、整数集等,就体现了极限的思想.  (2) 函数:当自变量x趋向于无穷或者0时,反比例函数、指数

一、定义不清,混淆象限角与区间角  例1若α, β为第一象限角,且α>β,则  (A) sinα>sinβ(B) sinαβ,∴ sinα>sinβ,选A.  错因分析: 象限角的概念不清,误将第一象限角理解成0,上的角. 若取α=2π ,β=,可知A明显不对.  正解:第一象限角的取值范围为2kπ,2kπ (k∈Z), ∴ 当α=2π ,β=时,sinαsinβ,即三种大小关系都有可能. 选D.
