Grammar: the Present Perfect Tense.2. To know that they should protect the environment and make our world more beautiful.II. 问题导入话题如：What do you think of our environment now?III. 听录音1.听第一遍录音，让学生试图了解文章大意。2.看书听第二遍录音，找出与以前学过的一般现在时不同的句子。如：Hu Lan has just been toIV阐述主要词汇和短语1. Businessmen are afraid of newspapers and TV stations. 生意人害怕报纸和电台。be afraid of 意思是"害怕"。后跟名词或动词的-ing形式（指自己不能决定而突然发生的事）。be afraid后也可跟动词不定式表示"害怕做某事"即：be afraid to do sth.。另外，afraid后还可跟that引导的宾语从句，意思是"担心，恐怕"。如：（1）I am afraid of mice. 我害怕老鼠。（2）Don't be afraid of making mistakes. 不要怕犯错误。（3）I'm afraid to tell her the truth. 我不敢告诉她真相。（4）I am afraid (that) you are ill. 恐怕你是病了。2. As soon as other people hear it, they go out with their rubbish and throw it in. 当人们一听到它，他们就出来把垃圾扔进去。as soon as -就，引导时间状语从句，表示主句的动作紧跟从句的动作发生。必须注意 as soon as possible（one can），它表示"尽可能快地"。如：He'll write to me as soon as he gets to Beijing 他一到北京就会给我写信。3. taking care of our environment is very important. 保护好我们的环境是非常重要的。take care of保护，照顾，保管。如：Please take good care of your books. 请保管好你们的书。4If everyone makes a contribution to protecting the environment, the world will become much more beautiful. 如果每人都对保护环境做出贡献，那么世界将变得更加美丽。make a contribution to意思是"对做贡献，捐赠"。to是介词后跟名词或动词的-ing形式。例如：（l）Thomas made a great contribution to the world托马斯·爱迪生对世界做出了很大的贡献。（2）It is our duty to make a contribution to protecting the environment为环境保护做贡献是我们的责任。5. The more trees, the better的结构这里是"the more，the more"句型表述结构，它的意思是"越多越好；越，越"。例如：The more I think of it, the happier I am.我越想越高兴：The harder you work, the greater progress you will make.你越用功，进步就越大。V语法讲解1现在完成时态： have been(to)与have gone(to)都表示现在完成时态，表明动作已经发生了，但它们之间的含义是有不同的。1）"have been in + 地点名词"或者"have been + 表位置的副词"含义是"在某地呆得过多久"。例如：I have been here since I began to workIt's just like my home.我工作以来一直呆在这里。2）"have been to +地点名词"表示"曾经到某地去过（多少次）"。例如：Have you ever been here before?你以前到过这儿吗？3）"have gone to +地点名词"或"have gone + 表位置的副词"其含义是"到某地去了"（人已不在此地），注意：这种结构不用于第一人称，也不用于第二人称，它仅用于第三人称。2延续性动词与非延续性动词(1) 延续性动词表示动作能够持续发生一段时间的动词。如：be, have, live, teach, speak, talk, wait, wear, walk, sleep等。如：Miss Gao has been here since 7:00. 高小姐七点起就到这儿了。(2) 非延续性动词表示一个动作刚刚发生即告结束。如：come, reach, see, hear, leave, start, fall, join, die, get up等。它们只可以用于完成时态的第一种，说明某个动作的结果还存在。如： The film has begun电影已经开映。（现正放映）这类动词不能和表示一段时间的状语连用。如：要表达"王大爷已经去世两年了"应这样写：Grandpa Wang has been dead for two years. 而不能写成：Grandpa Wang has died for two years.注：在for+时间段或 since+时间点的词组或句子上进行画线部分提问要用how long。同时用how long开始的句子中的谓语要用延续性的动词（时态不限）。 VI. 课堂活动在黑板上展示一张纸厂的图片，讨论五分钟关于纸厂带来的环境污染问题（四人一组）。如：This is a paper factory, it makes paper, but it also makes smoke and waste water. I found the waste water was put into the river near it. The river has become very dirty. Lots of fish have died.然后每组代表与大家一起分享组员观点，尽量用现在完成时来表达。VII. 布置作业1. Do Exercise 3 orally with the class.2. Talk something about the environment.
