XB3 Unit 3　ENVIRONMENTAL PROTECTION 单元小测 语境记单词 1 One graph shows that carbon dioxide and methane emissions are increasing year by year. As a result，they have destroyed our ecology and caused global warming. People burn fossil fuels to produce waste gases， which are then released into the atmosphere. We should fully realize that global warming is a worldwide problem. We must restrict the emission of carbon dioxide. We also call for a restriction on other waste gas emissions. There is a trend that global warming may cause ice and snow to melt，making polar bears，seals or penguins starve to death，and our planet not habitable. In order to sustain our survival as well as for the sustainable development of human society，we must fight for the protection of our living environment and ecology. We should seize every opportunity to advertise our protection policy through the media，such as TV and radio broadcasts. This is a hard and comprehensive task，and we must frequently warn people about it. 一张图表显示，二氧化碳和甲烷的排放量正在逐年增加。结果，它们破坏了我们的生态，导致了全球变暖。人们燃烧化石燃料产生废气，然后它们被排放到大气中。我们应该充分认识到，全球变暖是一个世界性的问题。我们必须限制二氧化碳的排放。我们还呼吁限制其他废气的排放。有一种趋势是，全球变暖可能导致冰雪融化，使得北极熊、海豹或企鹅 饿死，我们的地球无法居住。为了维持我们的生存，以及为了人类社会的可持续发展，我们必须为保护我们的生存环境和生态而奋斗。我们应该抓住一切机会，通过电视和无线电广播等媒体宣传我们的保护政策。这是一项艰巨而全面的任务，我们必须经常提醒人们注意。 2 Our reform and opening-up policy aims not only to reform the economic system，but also to build a harmonious well-off society.
