五、任务型阅读
Today I will introduce something about footprints to you. Footprints mean the influence that a person's or an organization's activities have on the environment. Let's take the example of Mr Brown's footprints.
Water footprint
Water is the source of life. We use water directly for drinking, cooking and washing, but we also use water indirectly for producing things such as food, paper and cloth. A water footprint tells us how much water is being used. It can help us come up with ways to save water. You can learn about how your daily habits influence your water use through the food you eat,the things you buy and even the energy you use.
Carbon(碳) footprint
A carbon footprint is the total amount of CO2 a person or an organization produces. We can use it to understand the influence of personal behaviour on global warming(全球变暖). Most people are surprised when they see how much CO2 their activities create.Then they begin to think about changing their daily habits to reduce their carbon footprints.For example,they can walk instead of using a car.

2.seat　句意:在公交车上,Lily经常把她的座位让给老年人。
3.divided　句意:我们被分为四组去捡公园里的垃圾。divide…into…是固定搭配,意为"把……分成……",此处用的是被动语态。
