4、动来保护我们的环境。但是，我们现在面临的主要问题是什么？The greenhouse effect温室效应The atmosphere around the Earth is necessary for all living things. It is like the glass of a greenhouse, letting sunlight in and keeping heat from getting out. Without it, the Earth would be the same as the Moon - cold and lifeless.地球上空的大气层对地球上的所

5、有生物都至关重要。它就像温室的玻璃，让阳光射入温室，防止室内热量流失。如果没有大气层，我们的地球会变得和月球一样寒冷而毫无生机。When we burn fuels such as petrol and coal, we produce a gas called carbon dioxide (CO2). Too much of this gas pollutes the atmosphere, and causes it to keep in too much heat. As a result of the greenhouse effect, the Earths temperature

6、 is increasing. This causes sea level to rise, and in the future may cause cities to disappear.当我们燃烧汽油和煤炭等燃料的时候，燃料燃烧就会产生二氧化碳的气体。大量的二氧化碳会污染大气层，使热量得不到释放。由于温室效应，地球的温度正在上升。这使得海平面也跟着上升，在未来，许多沿海城市可能会消失。Cutting down forests大量砍伐森林Every year, we destroy nature by cutting down huge areas of forests. This make

7、s the greenhouse effect worse because trees take in CO2 and produce oxygen. Cutting down trees also destroys the homes of the animals that live in our forests, and causes the surface of the soil to be easily destroyed by rain. This can result in floods and even more damage to the environment.每年，我们砍伐

8、大量的森林，破坏了大自然的环境。由于树木能够吸收二氧化碳，释放氧气，树木遭到砍伐使得温室效应变得更加严重。砍伐树木同时也破坏了生活在森林里动物的家园，也使得裸露在地表的土壤更容易随雨水流失。水土流失会造成洪水泛滥以及更严重的生态灾难。Bad habits不良习惯Many of our habits cause pollution. People often use things once and then throw them away, or leave them on the ground as litter. This creates mountains of rubbish and p

9、ollutes our land and seas.我们的许多习惯会污染环境。人们通常喜欢用一次性的物品，用完之后就把它们扔掉，或者扔在地上成为垃圾。这使得垃圾成山，污染了我们的土地和海洋。In order to protect the environment, we need to take proper action. We should be different from many consumers and become green consumers. This means that we should only buy and use products friendly to th

10、e environment. We should also recycle as many things as we can. We can reuse things for the same purpose as before, or we can use them for new purposes. If we just learn to live in new and different ways, we can make a difference.为了保护环境，我们需要采取合适的行动。我们需要和不良消费者区别开来，成为“绿色的”消费者。这意味着我们需要购买和使用对环境有益的商品。我们也

11、应该尽可能地重复利用资源。我们可以像以前一样重复使用某种东西，也可以换一种方式来使用。如果我们学会以一种新的方式生活，我们一定能够有所作为。More PracticeThe journey of a plastic bottle塑料瓶之旅I am a plastic bottle. A week ago, I was on a supermarket shelf.
