答案解析部分
1．Dear Jim,
I am writing to tell you something about water.
Everyone knows that water is important to all living things. However, much water is wasted every day. What's worse, there are many people in the world that can't have clean water to drink.
As for how to save water, here is some advice from my classmates. First, we should do something small in our daily life. Fox example, we should turn off the tap as soon as we finish using it. Second, we can recycle water. Third, everyone should know the importance of water. Only when all the people work together can more water be saved.
Let's work together to save water!
Best wishes!
Yours
Li Hua

2．Hi, everyone. Today I would like to tell you how the water forms. First, the Sun heats the water in the sea. The water becomes vapour and rises from the sea. Then, more and more vapour forms in the air and makes clouds. When the vapour cools, it becomes small drops of water. Then the small drops of water becomes too heavy to stay in the air. Finally, rain falls.

Today I would like to tell you how the water forms."直接引入主题，告诉听众将要讲解的内容是关于水的形成。其次描述过程：答案中详细描述了水形成的整个过程，从海水受热开始，到水蒸气形成、云层形成、水蒸气冷却变成水滴，最后雨水落下。逻辑连贯：答案中的各个步骤之间逻辑清晰，层层递进，使得整个讲解过程易于理解。使用的句型短语引入主题：Hi, everyone.
