Part 1The earth is becoming warm 1. Please find out the reasons why the earth is becoming warm from the lesson.--- Human activity

--- The burning of fossil fuels---

byproducts---greenhouse gases---

the level of carbon dioxideRead and answerTranslate the sentence into Chinese.

There is no doubt that the earth is becoming

warmer and that it is human activity that has

caused this global warming rather than a

random but natural phenomenon.

毫无疑问，地球在变暖，而地球变暖正是人类活动导致而成的，并非是一种无规律的自然现象。 Can you say something about the

greenhouse effect?

-- Is it caused by human activity or is a natural phenomenon?

--Do we need greenhouse gases? Why?

--If there are too much greenhouse gases, what problems can be caused?

1) It is a natural phenomenon.

2) We need those gases. Without the greenhouse

effect, the earth would be about thirty-three

degrees Celsius cooler than it is.

3) It will cause the global temperature to

go up.

1) … a natural phenomenon.

2) …need ... without …., …would be … cooler than ...

3) …cause …to go up.

Can you retell now? 1.Who found out the amount of carbon dioxide in the atmosphere from 1957 to 1977?

but I think…As far as I'm concerned, It is …that…In my opinion,… In my opinion, global warming is not a problem that can be ignored. We should do something to avoid the risks ahead. As students, we should start from leading a low-carbon daily life. For example, at home, we can turn off the running water while brushing our teeth. We can ride a bike to school. And at school, we can recycle the paper. There are many things we can do to help. And please remember, no matter how

small these things may

look, your contribution

counts! United, we can

make a big difference! Draw mind map

Students can draw here. Write a short passage about the effects of global warming and what we should do.

Read the short passage and finish the questions after class.
