{{B}}Happy Earth
Day{{/B}} {{B}}The Good News{{/B}} Here’s the good news: our air is cleaner, our lakes are purer, our forests are healthier, endangered species are recovering, toxic emissions are down, and acid rain has diminished dramatically. And yet, if you’ve looked at a newspaper or watched the evening news lately, you might think our environment is under siege(围攻). Media coverage of the environment is heavy on doomsday, but the truth is not at all break: nearly all environmental trends in the United States are positive and have been for years--if net decades. Eco-legislation, green organizations, corporate cooperation and new inventions have all quietly steered our environment in a positive direction. We can’t afford to be complacent(自满的), though--especially when it comes to A. Global warming. B. Acid min. C. Toxic emission. D. Environment. [单项选择]

Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense. 我来回答: 提交
