IV. Read the passage and then underline the sentences with "time adverbial clause", translating them into Chinese.
The water cycle is a fascinating and never - ending process. It is not boring. It is the key to keep the balance of water on Earth. The cycle begins when the sun shines brightly, heating up water in rivers, lakes, and oceans. As the water heats up, it turns into vapour and rises into the sky. This process is called evaporation. It can be easily observed on a hot summer day when puddles dry up quickly.
Once the water vapour reaches high altitudes, it cools down and condenses into tiny water drops, becoming clouds. When these clouds are fully loaded with water drops, they release the water back to the ground in the form of rain, snow, or hail. Rainwater then pours into rivers, which flow into the ocean, or seeps into the ground through small holes until it becomes groundwater.
Plants absorb this groundwater through their roots, and animals drink from rivers and lakes. Even a small drop of water takes part in this continuous cycle. Understanding the water cycle helps us realize that all water sources are interconnected. This knowledge tells us the importance of protecting every water source and pollution in one area can spread and affect the cycle.

答案：1. The cycle begins when the sun shines brightly, heating up water in rivers, lakes, and oceans.（当太阳明亮地照耀时，水循环开始了，加热了河流、湖泊和海洋中的水。）
2. As the water heats up, it turns into vapour and rises into the sky.（当水受热时，它变成水蒸气并升入天空。）
3. It can be easily observed on a hot summer day when puddles dry up quickly.（在炎热的夏日，当水坑很快干涸时，这一过程很容易被观察到。）
4. When these clouds are fully loaded with water drops, they release the water back to the ground in the form of rain, snow, or hail.（当这些云充满水滴时，它们以雨、雪或冰雹的形式将水释放回地面。）
5. Rainwater then pours into rivers, which flow into the ocean, or seeps into the ground through small holes until it becomes groundwater.（雨水然后流入河流，河流汇入海洋，或者通过小孔渗入地下，直到它变成地下水。）
V. Read the passage and answer the following questions.
Saving water is an important task for everyone. We can do many simple things at home. First, shut the tap while brushing teeth. This immediately saves litres of water. Next, we can use waste water to water plants or clean floors.
Take short showers, not long baths. When using the dishwasher, use the energy - saving mode. In washing clothes, use water - efficient machines and only full loads.
Fix leaks—if a tap does not shut fully, it will drop water every minute. A kilo of water lost each day adds up to hundreds of litres a year. This is why we need to raise awareness.
In public places, signs remind people to save water. People do research on new technology like smart taps and indirect reuse. Saving water is not hard. It takes carefully attention and habit. Everyone can agree saving water is our responsibility.
1. How many ways of saving water are mentioned at home in this passage? What are they?
2. According to the third paragraph, why should we raise awareness of saving water?
3. What's the title of the passage?
答案：1. Six ways. Shut the tap while brushing teeth; use waste water to water plants or clean floors; take short showers instead of long baths; use the energy - saving mode when using the dishwasher; use water - efficient machines and only full loads when washing clothes; fix leaks.（六种方法。刷牙时关上水龙头；用废水浇花或擦地；洗短时间的淋浴而不是长时间的盆浴；使用洗碗机时使用节能模式；洗衣服时使用节水机器并且只洗满载的衣物；修理漏水处。）
2. Because if a tap does not shut fully, it will drop water every minute and a kilo of water lost each day adds up to hundreds of litres a year.（因为如果水龙头没有完全关上，它每分钟都会滴水，每天流失一千克水，一年就会累计成几百升水。）
3. Saving Water（节约用水）
