The natural wonders which have been hidden by pollution for years appear again. Cleaner air and water allow them to show all their beauty once again. But there aren't any people to admire such an amazing world. What a sad thing to think about! Throughout history, humans have left so many marks on the earth.

What changes can you make to "permit nature to have her way"? Think and share we should let nature follow its own rules and natural course. We ought not disturb or control nature. Humans need to respect nature and live in harmony with it instead of damaging it. We can stop polluting the environment, protect wild animals and plants, and avoid destroying forests. We should respect natural rules and live in harmony with nature. Post-reading 1.What's ourrelationship with nature? 2.What is "nature's way"? 3. How is it different from ours? Learning to think for question We should live in harmony with nature. We are part of nature and need to respect it instead of damaging it. It means nature’s own rules. Nature can develop and change by itself without human disturbance. Nature’s way lets all living things develop freely and keep balance naturally. But our human way often disturbs nature and pollutes the earth for development. Post-reading 4.What's the meaning of "permit"? 5.Why did Montaigne use this word? Learning to think for question It means we should allow nature to follow its own rules instead of stopping or changing it. Montaigne chose the word permit on purpose. The word "permit" means "to allow". It tells us that nature has its own way and power. Humans are not the masters of nature. We should not try to change or rule nature.
