Part 1 (Para. 1)This is the introductory part in which the author raises the theme that people live in two worlds.Para. 11. What are the two worlds that people live in?The two worlds refer to the natural world and the world of human creation.2. What is the common, unthinking attitude towards the two worlds?The attitude is-we are responsible for events of our own world, but not for what occurs in the natural world.Part II (Paras. 2-5)In this part, the author explains why the two worlds are at war.Para. 23. Now, on a planetary scale, this division has been breached.Why does the author say so?Globally, the two worlds are no longer separated, having nothing to do with each other. What humans do in the techno sphere will have effect on the ecosphere. This is a transitional sentence, linking up the following part with the first paragraph. It also leads to further explanation of the interaction between the two worlds.4. …even droughts, floods, and heat waves may become unwitting acts of man.(1) What people do may unintentionally cause droughts, floods and heat waves.(2) Do you think this is a correct statement?Yes. For example, in order to reclaim land, or to gather firewood, people would cut down trees and bushes, thus causing deforestation. Without the protection of forests, there will be floods, droughts and mudslides.Para. 35. Like the Creation, the portending global events are cosmic…Like the Creation of the universe, events that happen in this world may have vast effects, especially on the relationship between the planet Earth and the sun.6. Solar radiation--largely visible and ultraviolet light---is a vast stream of energy that bathes the Earth‟s surface太阳能, 主要是可见光和紫外线, 是沐浴着大地表层且取之不尽、用之不竭的能量……7. Solar energy fuels the energy-requiring processes of life；it creates the planet‟s climate and governs the gradual evolution and the current behavior 0f its huge and varied population of living things.(1) …solar energy fuels the energy-requiring processes of life…The photosynthesis of plants is a case in point.(2) The current behavior of many animals and plants is the result of climate change overmillions of years.8. We have been tampering with this powerful force, unaware, like the Sorcerer‟s Apprentice ofthe potentially disastrous consequences of our actions.(1) tamper with：to interfere or meddle with, esp. to damage or corrupt(2) Why does the author say that we have be en behaving like the Sorcerer‟s Apprentice?That is because we have been doing things without knowing that they may have serious effects on the planet Earth.(3) 我们一直在滥用这股强大的力量, 就像传说中魔术师的徒弟一样, 我们并没有意识到我们的这种行为很可能会导致灾难性的后果。
