Unit 4 Global warming 話題誦讀 日積月累 [導(dǎo)語(yǔ)]　你知道全球變暖會(huì)給人類(lèi)的生活和環(huán)境帶來(lái)哪些變化嗎？ Short and Long Term Effects of Global Warming Climate change Global warming is causing the temperature of the earth to rise slowly，causing massive global changes to our natural environment. Rising sea level Global warming is rapidly melting glaciers around the globe，causing a rising sea level and possibly coastal flooding and other weather problems in the future. Ecosystem changes Global warming is changing certain ecosystems throughout due to temperature fluctuations.Animals and plants are being forced to adapt to this，and，as a result，are dying off. Breakdown of the ozone layer Global warming is creating holes in the ozone layer，primarily from human use of products that emit poisonous chemicals.The ozone layer absorbs UV radiation from the sun.The holes are causing amounts of poisonous chemicals present in our breathing air to increase at a rapid rate.

這對(duì)你我來(lái)說(shuō)很可能是無(wú)所謂的，但是跟其他自然變化相比而言，這卻是一種快速的增長(zhǎng)。 [句式分析] when pared to...是時(shí)間狀語(yǔ)從句的省略，其完整形式為：when it is pared
