专题与实践活动
全球变暖的直接诱因是温室气体排放量居高不下所造成的，而人们在日常生活中的资源浪费制造了大量不必要的温室气体。其实，普通人只要在生活中稍微加以注意，算上一笔“节能账”，就能节约不少能源，减少温室气体的产生。
为增强节约意识，近日，校学生会在全校发起了一场“个人行动改变世界大气候”活动。请你担任活动的宣传员，帮助完成以下工作。
(1)第一段中有一个病句，请找出并修改。                            。(2分)
(2)仿照例句为活动拟写一条倡导节约环保的宣传用语，要求引用古诗句并说出诗句中蕴含的物候规律。
例句：愿人人节约一度电，让家园“处处闻啼鸟”。
宣传语：                                                 。(2分)
物候规律：_______________________________________________________。(2分)
(3)在活动中，男女生开展了节约竞赛。近期，学生会对住校男生和女生的节约情况作了调查，
请你用简洁的语言概括调查表所反映的基本情况。(3分)

	3月		4月		5月

寝室用电量	650度	280度	631度	252度	613度	220度

阅读下面的短文．并根据短文后的要求答题。
Since 1850．the temperature of Earth’s surface has increased about 0.6°C．Scientists predict it may warm much more by the end of this century．Who’s turning up the heat? Well, it seems that we are! Some of this global warming may be natural．However，nearly all scientists now agree that most of it is due to peoples actions．Over the past 150 years, we've added huge amounts of certain gases, especially carbon dioxide（CO2）to the air．These gases can keep heat near Earth's surface，so more carbon dioxide means more heat is kept near Earth's surface．Global warming may change the weather in ways that lead to more severe storms，floods and droughts．
We add carbon dioxide to the air when we burn things, especially fossil fuels．Fossil fuels are energy sources formed from the remains of plants and animals that lived millions of years ago．Coal，oil，and natural gas are all fossil fuels．People in the United States and other countries started bunting large amounts of fossil fuels more than a century ago．The amount d fossil fuels being burned each year has been increasing worldwide．The more we burn，_____________________．
What can we do to help? Nowadays to live a low-carbon life is quite popular in the world． Low-carbon means to reduce the amount of carbon dioxide．Saving energy and reusing are the key words. In fact, even the simplest everyday activities can make our lives low-carbon．
