creates jobs and supports industries like tourism, business, and leisure.
Water is not only essential for life, but is also important for human society. Let's explore the role water plays in the development of cities.
If you look at a population map of any country in the world, you will see that most people live close to water. The world's biggest cities are next to rivers, lakes or the sea. This isn't an accident. We use water for all kinds of things in everyday life, and we also need it for agriculture and for trade.
In fact, water creates jobs and helps different industries to develop. At the end of the 18th century, water played a big role in the Industrial Revolution. Water powered the first machines in the clothes industry, such as Richard Arkwright's spinning machines.
1 Read the article and find out why water is important for cities.
It also provided the first steam engines with steam. Thanks to rivers and oceans, businessmen could ship their goods overseas. The growing global trade created more jobs and provided more income for people. As a result, the cities that were close to water grew much larger.
By 2008, over half of the world's population lived in cities. Nearly all of these cities are on the coast or by rivers or lakes. This is because cities need water for people's homes, industry, business, tourism and leisure activities. Throughout history, water helped create and develop cities. It is now our duty to make sure we don't waste water or pollute it.
Notes
Before people invented farming, they made a living by fishing or hunting. Around 12,000 years ago, people began growing crops, so it became very important to have good sources of water. Eventually, people started using water power to make flour. They also built pipes to transport water.
Notes
在发明农耕前，人们通过捕鱼或狩猎谋生。 大约1.2万年前，人们开始种植庄稼，因此拥有好的水源变得非常重要。 最终，人们开始使用水力来磨面，还建造了管道来运输水。

Cross-curricular connection I Biological science
Water is important to life. About 55%–60% of the adult human body is water. Let’s find out more facts about water in the human body.
The water in our bodies
All living things need water. In fact, water is an important part of all plants and animals. For example, about 95% of the weight of a cucumber is water. For animals, that figure is usually around 60%.
When we are born, about 70%–80% of our body weight is water. This number goes down as we grow up. For an adult man, water makes up about 60% of the body weight. The amount of water is a bit lower for women: around 55%. This is because women usually have more body fat than men.
A lot of water leaves our bodies every day, so we need to replace it. Adults need to drink about 2–3 litres per day to stay healthy. Every time we go to the bathroom, we lose water. Every day, there is around 1.5 litres of water in our urine. If your urine is very yellow, you need to drink more water. The body also loses water to help it cool down. This is called sweat. We lose about 500 ml of water as sweat per day.
It is normal to sweat a lot when we do sport or go out in hot weather. However, if we lose more than 5% of our body weight in water, we will get tired. It is dangerous to lose more than 10%. If that happens, we will feel ill. Remember to bring a water bottle every time you play sport!
What is the main idea of the passage
It mainly introduces the significance of water for living things and water in the human body.
1. What percentage of a cucumber's weight is water

3.Why is the amount of water in women's bodies a bit lower than that in men's
This is because women usually have more body fat than men.
4. How much water do adults need to drink per day to stay healthy
Adults need to drink about 2 - 3 litres per day to stay healthy.
5. What will happen if we lose more than 10% of our body weight in water
If we lose more than 10% of our body weight in water, we will feel ill.

What else does the body use water for
作为溶剂：
水是一种良好的溶剂，许多营养物质如葡萄糖、氨基酸、维生素等都需要溶解在水中才能被人体吸收和运输到各个组织器官。同时，代谢废物如尿素、尿酸等也需要通过水的溶解才能随尿液等排出体外。
参与化学反应：
水直接参与人体的许多生化反应，如水解反应、氧化还原反应等。例如，在食物的消化过程中，水参与淀粉、蛋白质、脂肪等大分子物质的水解，将其分解为小分子物质，以便人体吸收利用。
调节体温：
水的比热较大，能够吸收和释放大量的热量而自身温度变化相对较小。当人体产生热量过多时，水分通过皮肤表面的汗液蒸发带走热量，从而维持体温的相对稳定。在寒冷环境中，水又能减缓体温的散失，起到保暖作用。
