本单元主题大观念是：能阐述水的各种事实信息、水的重要性以及水对人类的贡献，树立爱护水源、节约用水的意识，探究人与自然和谐共生的途径，在日常生活中养成节约用水、绿色环保的良好习惯。
本单元在Reading、Listening、Writing及More Practice的语篇里，学生已经获取了一些关于水的特性及重要性的相关信息，但是关于人类对于水的污染及保护措施的输入比较少，对“人类与自然和谐共生”这一主题探究不深。另外，本单元对于水在民生方面的用途也涉及甚少。基于以上语篇分析，我选取了A篇关于水污染现状及对水的保护措施的文章，以及B篇最新研究发现月球上发现了水源，以拓展学生在环保措施和途径方面知识，也为Culture Corner部分关于水的特殊用途进行延伸和补充。
二. 单元主题拓展阅读
A篇
Over two thirds of Earth’s surface is covered by water and less than a third is taken up by land. As there are more and more people on the Earth, people are using more and more water on the planet.
We know that pollution is a human problem: Before the 19th century Industrial Revolution, people live in a better environment. As industrialization spread around the planet, the problem of pollution has spread with it. When the number of people on the Earth was much smaller, no one believed water pollution would ever be a big problem. It was once popularly believed that the oceans were too big to be polluted before the 19th century. Today, with around 7 billion people on the planet, it has clearly showed that there are problems. Water pollution is one the of the most serious ones around the world now. How can we stop water pollution
Studying
Making people get to know the problem is the first step to solve it. It can make a great difference for the water environment if people study the problem. They can know more about the danger of the water pollution.
Having rules
Having rules can make it tough for people to pollute water. People have to think about the pollution more often and cannot pollute the water or oceans easily because of the rules. Most countries also have their water pollution rules. In the United States, for example, there is the 1972 Clean Water Act and the 1974 Safe Drinking Water Act.

Most scientists agree that the best way to stop pollution is through something called “the polluter pays” principle. This means that whoever produces pollution should have to pay to clean it up, one way or another.

B篇
Water is very important to us. We can't live without water. As we all know, there is much water on the Earth. But do you know if there is water on other planets
Scientists found water in little glass balls on the moon. ▲ But now we know there is water on the surface（表面）and inside rocks.
A professor named Mahesh Anand said that when the sun was shining, he saw water molecules moving on the moon. A team of scientists from China studied 117 glass beads（珠子）that the Chang'e-5 spaceship brought back to the Earth in 2020.The beads were made of very small space rocks. The rocks hit the moon＇s surface and melt（融化）the ground. The melted material cooled into round glass beads. The beads were as wide as a strand of hair.
The scientists said that the glass beads are probably the main place where water on the moon comes from. The beads may make up about 3% to 5% of the moon's soil. The scientists there could be about 300 billion tons of water inside all the beads on the moon.
If someone heats the glass beads up just a little, around 100℃,he can get the water out. The European Space Agency's robot drill, PROSPECT, might be the first to try to do this in 2025 .
NASA will go to the moon's South Pole next year to look for ice. It will take people to the moon in the next few years.
