新西兰野生鲸鱼在海滩搁浅
A wildlife keeper puts water on a beached (浅的) pilot whale to keep it alive (活着的). On March 18, 34 pilot whales were beached on New Zealand's South Island. Only five stayed alive. Wildlife keepers said they had been out of the water for a while.
Beached whales are nothing new on the South Island. The beach is known as a death trap (死亡陷阱) for whales, with more than 10 whale stranding events (搁浅事件) in the last 15 years. The largest was in February 2017 when about 700 whales beached. Nearly 250 died reported Yahoo News..

Whales are huge animals. They live in the sea and eat small fish and other sea life .One interesting fact is whales can jump high out of the water. Another interesting fact is that they can sing beautifully.
Some kinds of whales are in danger because humans catch them for meat, fat and oil, and use whale parts to make things like candles and soap .Whales are also in danger because of water pollution.
In my view, all governments should make rules on whale protection and stop people putting rubbish into the sea. Meanwhile, we should learn more about whales and protect their environment.
By doing this, whales are certainly able to live a happy life. Therefore
let's do it now!

T：OK class is over ，Look forward to meeting you next time, Goodbye.
教学反思
本节课是写作课，八年级学生已经积累了一定的英语词汇，有一定的词汇基础，但初二学生两级分化严重，对写作课的学习稍微有些畏难情绪。因此，此课采用了大量图片、视频吸引学生注意和兴趣，小步子循序渐进以降低难度。
在问候环节就告诉学生认识一位朋友，引起学生好奇心，在导入环节出示句子，让学生猜猜看，激发学生学习兴趣，使学生快速进入学习状态。
先从了解鲸鱼为起始点，然后让学生了解鲸鱼所处的危险处境，让学生知道造成鲸鱼处境的原因，利用报道和大量图片，引发学生保护鲸鱼的责任心，层层递进，符合学生认知，引导学生思考该怎样保护鲸鱼，最后引导学生进行写作。让学生意识到爱护环境，保护镜宇刻不容缓。在作业的设置中以制作海报的形式回顾所学知识。
