Warming up & ReadingTASK1
Make another list of as many sources of energy as you can .
Which energy sources on your list are renewable and which are non-renewable?Discussion:Windmills(风车), renewable sources of energy: a coal power station, non-renewablean oil refinery(精炼厂), non-renewablea nuclear power plant, non-renewableSolar panels(太阳电池板), renewablea hydro-electric dam, renewableTASK2
1. Have you ever seen a greenhouse?used for growing plants, especially during cold weather.2. How does the greenhouse work?The air inside was warm because the
glass traps (挡住, 吸收) the heat from the
sun and keeps it from escaping (逃跑).
This makes the greenhouse heat up (热量
上升) and so the plants can grow
throughout(在…期间) the cold period.2. Greenhouse Effect Global warmingGreenhouse gases trapped the heat from the sun, which causes the temperature of earth goes up. glaciers melt
冰川融化 species extinction
物种灭绝sea level rises
海平面上升Global Warming lead in
Can you think of some natural disasters
(自然灾害) because of the extreme weather? What is the weather like today?smogextreme weather eventsdroughtfirefloodsandstormtyphoonTsunamihigh temperatureWhat has caused the extreme climate?
