关于全球气候变暖英语作文【一】
什么是“温室效应”呢？这是“温室气体”进入大气层，因为它具有隔热和吸热的功能。它在大气层中增多的结果是形成一种无形的玻璃罩，使太阳辐射在地球上的热量无法向外层空间发射，结果是让地球表面变热起来。
为什么会产生“温室效应”？由于人口急剧增长，工业迅速发展，呼吸产生的.二氧化碳，石油等燃烧时产生的二氧化碳越来越多，又由于对森林的砍伐，大量的农田被建成工厂，破坏了植被，减少了将二氧化碳转化为有机物的条件。再加上地表水域的逐渐减少，降水量大大降低，减少了吸收溶解二氧化碳的条件，破坏了生成与转化动态的平衡，就使大气中的二氧化碳含量逐年增加。
“温室效应”的后果又是什么？它可以使海平面上升。这样低地被淹；地表水和地下水盐分增加，影响供水：生态平衡遭到破坏，许多生物物种加速灭绝。
我们怎么样去减少“温室效应”给我们带来的危害？我们在日常生活中，随手关灯，节约用电。出门可以坐公交车或骑自行车，能步行更好，以节约汽油的消耗量，减少二氧化碳的排放量。
从我做起，阻止全球变暖。

记得在我上二年级的时候，发生过这样一件事。
那天中午，我正在房间里抱着爸爸给我新买的那本《十万个为什么》，翻来覆去地看个不停。妈妈正在厨房里为了做菜忙得火热朝天。
忽然，听到妈妈喊一句：“儿子啊，没有味精了！你帮我到公园门口的小超市买一包味精回来好不？”我在看书，正看的起劲，想也没想就脱口而出：“好。妈妈塞了20元钱到我手里。我还沉浸在书里，一手拿住书，另一手拿住钱，穿好鞋子就边看书边走到了小卖部门口。”
我照妈妈的话，用极高的童音对着小卖部里面的阿姨说：“阿姨，要一条围巾。”
里面的那位阿姨很是奇怪：“现在大热天的买什么围巾啊？”
我说：“我也不知道，我妈妈要我买的。”
那位阿姨就拿了一条便宜的17元的围巾给我，找回我3元钱后，我看着书回到了家里。
刚进家门，妈妈就高兴地欢呼：“噢，味精来了，味精来了。”
我说：“妈啊，你大热天的买围巾干什么？”
妈妈说：“做菜要用啊！做菜不给味精味道就差很多！”
我心里暗暗默念：以后如果我会做菜了，一定每次都要给一条围巾。就把那条围巾递给了妈妈。
妈妈拿到围巾，顿时傻了眼：“我要你买的味精，你买围巾回来干什么？”
我大惑不解：“就是你要我买围巾回来的啊！”
这时我忽然想起妈妈吩咐我的时候我的脑袋里全是书，当然会听错。便说：“。不好意思。我看书太认真。听错了。”脸涨得通红。
妈妈开心地笑了，把我搂进怀里。
这件事再回想起来，还能让我开怀大笑。

Sometimes I dream about life in the future. What will it be?
Perhaps some people will go to the moon for a holiday or even live on the moon,and some scientists will build cities under the sea to make people live there. We can have a medical examination or do some shopping without leaving our homes,which makes the life more convenient. Maybe we will also do some shopping and work at home.
And I'm sure there'll be more educational programmes on the radio or TV or by the Intemet or videophones,so perhaps some children won't need to go to school every day. They'll study at home.
In the future,all electric equipment at home is under the con-trol of computers. People can learn about the situation of the house by working on the computer at the office. No people like doing housework. Maybe each family will have a robot. Every day we can tell the robot what to do-shopping,housework and so on. believe the dream will come true some day.
