四、阅读理解（共20小题，满分20分）
阅读下列短文，从各题所给的A、B、C、D四个选项中，选出最佳选项。
（A）
The water cycle is nature's way of recycling water. It has four main stages.
First, the sun heats water in oceans, lakes, and rivers. This turns the water into steam, which rises into the air. This stage is called evaporation (蒸发).
Next, the steam cools down high in the sky and forms clouds. This is called condensation (凝结).
Then, when the clouds get heavy, water falls back to the Earth as rain, snow, or hail (冰雹). This is precipitation (降水).
Finally, the water flows back into oceans, lakes, and rivers. Some water also goes underground. Then the cycle starts again.
The water cycle is important because it provides fresh water for plants, animals, and humans. Without it, we would not have enough clean water to use.
How many main stages does the water cycle have
A. Two. B. Three. C. Four. D. Five.
What causes water to turn into steam
A. The moon. B. The sun. C. Wind. D. Rain.
What happens during condensation
A. Water turns into steam. B. Steam forms clouds.
C. Water falls as rain or snow. D. Water flows back to oceans.
What is precipitation

Digital technology has changed how we live. Here are some popular digital tools and their uses.
Smartphones are the most common. We use them to call, text, and access the Internet. Many apps on smartphones help with daily tasks. For example, weather apps tell us the forecast, and map apps show us directions.
Tablets are larger than smartphones but smaller than computers. People often use them to read e-books, watch videos, or study online. Students can take notes on tablets and share them with classmates easily.
Smartwatches are worn on the wrist. They can track steps, heart rate, and sleep. They also connect to smartphones, so users can get calls or messages without taking out their phones.
These digital tools make life more convenient. They help us work, study, and stay connected with others.
What can we NOT do with smartphones
Make calls. B. Read e-books.
C. Access the Internet. D. Get weather forecasts.

Water pollution is a serious problem. It happens when harmful substances (物质) get into water. These substances can be chemicals from factories, rubbish from cities, or oil from ships.
Polluted water is dangerous. It can make people sick if they drink it. It also harms fish and other water animals. Some plants that grow in water may die, too.
There are ways to stop water pollution. Factories should clean their waste before pouring it into rivers or oceans. People should not throw rubbish into water. We can also use fewer chemicals in farming, as they often flow into water.
Everyone can help. By not wasting water and keeping it clean, we can protect this important resource.

Digital life has many benefits, but it also has problems.
One benefit is easy communication. With apps like video call, we can talk to people far away anytime. This helps families and friends stay connected, even if they live in different countries.
Another benefit is convenient learning. Online courses allow students to study at home. They can watch lessons again if they don't understand, which helps them learn better.
However, digital life can be bad for health. Staring at screens for too long hurts eyes. Sitting still while using computers or phones can lead to weight gain.
Also, too much digital time may stop people from doing outdoor activities. This can make them feel lonely or sad.
Like many things, digital life is good if we use it wisely. We should balance screen time with other activities.

六、任务型阅读（共10小题，满分20分）
Water and digital technology are closely related. Digital tools can help us manage water better.
Smart meters (智能水表) are one example. They track how much water a home uses every day. The data is sent to a phone app, so people can see their water use and find ways to save. For example, if the meter shows high use in the morning, users may try to take shorter showers.
Another tool is water sensors (传感器). They are placed in rivers or lakes to monitor water quality. If the water is polluted, the sensors send alerts (警报) to scientists quickly. This helps fix the problem faster.
Some apps even teach people about water. They have games and quizzes to help children learn how the water cycle works and why water conservation is important.
By using these digital tools, we can use water more wisely and protect it for the future.
Task 1: 判断对错，True (T) or False (F)。
( )1、Digital tools can help manage water better.
( )2、Smart meters track how much electricity a home uses.
( )3、Water sensors monitor water quality in rivers or lakes.
( )4、Apps can teach children about water through games and quizzes.
( )5、Digital tools are not useful for water conservation.
Task 2: 回答以下问题。
What do smart meters track

One benefit is easy communication. With apps like video call, we can talk to people far away anytime. This helps families and friends stay connected, even if they live in different countries.
Another benefit is convenient learning. Online courses allow students to study at home. They can watch lessons again if they don't understand, which helps them learn better.
However, digital life can be bad for health. Staring at screens for too long hurts eyes. Sitting still while using computers or phones can lead to weight gain.
Also, too much digital time may stop people from doing outdoor activities. This can make them feel lonely or sad.
Like many things, digital life is good if we use it wisely. We should balance screen time with other activities.

六、任务型阅读（共10小题，满分20分）
Water and digital technology are closely related. Digital tools can help us manage water better.
Smart meters (智能水表) are one example. They track how much water a home uses every day. The data is sent to a phone app, so people can see their water use and find ways to save. For example, if the meter shows high use in the morning, users may try to take shorter showers.
Another tool is water sensors (传感器). They are placed in rivers or lakes to monitor water quality. If the water is polluted, the sensors send alerts (警报) to scientists quickly. This helps fix the problem faster.
Some apps even teach people about water. They have games and quizzes to help children learn how the water cycle works and why water conservation is important.
By using these digital tools, we can use water more wisely and protect it for the future.
