  8. HOW LIFE BEGAN ON THE EARTH?

  9. Pangu separates the sky from the earth

  10. Nuwa makes human beings

  11. The Big Bang

  12. How many parts can the text be divided into? Two parts: Part 1 (para 1) Part 2 (para2.3.4) Water made it possible for life begin to develop. The development of living things.

  13. Energetic dust A solid ball Explode atmosphere water

  14. Water made it possible ________________________ for life to begin to develop.

  15. 2 1 small plants in water 2 shellfish and all sorts of fish 4 5 4 insects (on land) 3 green plants on land 5 amphibians (on land and in water) 7 8 9 6 forests 7 reptiles (on land) 8 dinosaurs (on land) 9 mammals (on land)

  16. Water ________made it possible for life to begin to develop.

  17. Plants encouraged the development of _____________________________. early shellfish and all sorts of fish

  18. insects Later _____________ appeared. land animals amphibians

  19. When plants grew into forests, ______ appeared for the first time. reptiles

  20. Some huge animals, called _________, developed. dinosaurs

  21. When dinosaurs disappeared, _________ became more important. mammals

  22. small plants grow on the water shellfish & other fish appear plants begin to grow on dry land The development of life A cloud of dust→a solid ball→presence of water→ on the water→shellfish & other fish →plants begin to grow on dry land→insects and amphibians appear→retiles appear→dinosaurs appear→mammals appear insects and amphibians appear retiles appear dinosaurs appear mammals appear

  23. Discussion As a student, what little things can we do for the earth?

  24. Whether life will continue on the earth depends on human beings. Only if we care will we help, only if we help shall all be saved!
