一、教材分析
本课从课型上来讲是一堂语法课，根据课标要求，通过本课学习，重点培养学生的正确使用现在进行时这一时态的能力。由于学生已经学习了一般现在时，学生对时态有了初步的了解，对于学习现在进行时有很大帮助，但由于学生理解能力较差，进行这一语法教学还是有一定的难度的，因此我在教学的先采用图片呈现引导学生理解这一时态，然后再采用以“自主、合作、探究”为主的任务型教学法来展开教学。

广州深圳新牛津版教材七年级下册Unit4知识点小结
Unit 4 Save the trees 知识点小结1. Discuss the importance of trees. 讨论树木的重要性。
1）discuss及物动词，意为“讨论，谈论”。
We should discuss the problem face to face.我们应该面对面地讨论这个问题。
I have something important to discuss with you.我有要事与你商谈。
2）importance不可数名词，意为“重要性”，其前面加定冠词the。
the importance of意为“……的重要性”。
Do you know the importance of salt? 你知道盐的重要性吗？2. If I plant this seed in the ground, will it become a pear tree, Hi? 如果我把这粒种子种在地里，它会长成一棵梨树吗，Hi？If引导条件状语从句时，意为“如果”。
条件状语从句表示主句动作发生的条件，有从句的动作发生就会有主句的动作发生。
复合句一般都要遵循主、从句时态呼应规律。
1）主句（包括祈使句和情态动词can, may, must等的句子）用一般现在时，从句也用一般现在时。
You must see a doctor if you are ill.如果你生病了，你必须去看医生。
2）如果主句是一般将来时，从句要用一般现在时表将来。
即“主将从现”。
We will go out if it is fine tomorrow.如果明天天气好，我们就出去。
助记：if条件句不一般，几个要点记心间。
条件句放在前，逗号要放句中间。
条件句表事实，主句常用现在时；条件句表可能，主将从现要牢记。
The children will climb the hill if it __________tomorrow.A. won’t rainB.didn’t rainC.isn’t rainingD.doesn’t rain解析：在含有if引导的条件状语从句的主从复合句中，主句是一般将来时，从句用一般现在时表将来。

Tosontsagaan, are villagers in Inner Mongolia's Ejin Horo Banner(内蒙古伊金霍洛旗) ,where there is the Badain Jaran Desert (巴丹吉林沙漠) ,one of China's four biggest deserts. They have spent 16 years fighting against the desert.They plant trees in the desert area to keep the sand and protect the environment.Tubbat has planted more than 50,000 trees covering about the size of 133 football fields. "When I was a child,there were lakes, forests and animals. And it rained a lot," said Tubbat. "But sandstorms turned the green land into a desert."Tubbat started to plant trees in 2002 after he finished his job as a government official(政府官员).His wife supported his decision. They did all this for free and even spent most of their own money. " Many people do not understand why I do this.They don't know the happiness I feel when I see the land turn green again, " said Tubbat. " My wife's support gives me energy. Our children want us to live in a city. But this is not the right time. I want to grow more trees , " he said.Tubbat is happy that more people have begun to plant trees after hearing his story. Some have even visited him to learn how to plant trees in the desert. "Trees can bring rain and animals,"he said. "I want to be a tree, to grow up in the desert and hold the sand until I die."根据短文内容 .判断下列各句正(T)误(F)1.Tubbat and his wife have spent 16 years fighting against the desert.2.Planting trees in the desert area can keep the sand and protect the environment.3.The couple planted more trees to get more money.4.More people stopped planting trees after hearing Tubbat's story.5.According to the passage, Tubbat wants to spend his whole life planting trees. Ⅱ.任务型阅读Save the world's trees"When it comes to the earth, there is no time to waste," says the Earth Day Network. And that is right. Protecting our environment is very important, and world Earth Day was created in 1970 to ask more people to protect our environment. On April 22, people around the world celebrate Earth Day.Every year there is a special topic, and this year it is"Trees for the Earth", so Earth Day this year will be all about planting trees. They are planning to plant 7.8 billion trees within the next five years.That's a big goal, and you might wonder why trees are so important. It is because they can take in carbon dioxide (CO₂) and protect the air quality(质量) . CO₂ is a chemical in our atmosphere, but humans make too much of it. Each person makes about 2.3 tons a year, which is bad for the environment.Well guess what !Planting new trees is important because people cut down a huge number of trees. Last year, there were 3 trillion trees in the world, about 139 billion in China. But according to China Daily, the world’s total number has been almost cut in half since human civilization(文明) began. That's because 15 billiontrees are cut down every year.So we need to plant more to make up for(弥补) the ones we lost. One tree can take in 21.8 kilograms of CO₂ per year. And it's still one of the cheapest and best ways to get rid of CO₂.But don't forget that we can also help the environment by cutting down on how much energy(能源) and water we use every day. Every little thing helps.根据短文内容 ,回答问题 (1-4) ,英译汉 (5) 。
