（A）Hidden Mistakes in Home Electricity Use
Many families think they are using electricity properly, but there are some unnoticed（被忽视的） errors that lead to extra power consumption（消耗量）every day. These small mistakes are easy to fix, but few people pay attention to them in daily life.
One common mistake is that people often keep the fridge door open for a long time when picking food. The cold air inside will flow out quickly, and the fridge has to work extra hard to keep the temperature low. Another error is using old-style electrical devices, which need more energy to run than new models.
Some people also charge electronic devices all night, and the chargers（充电器）keep consuming power even after the devices are fully charged. Besides, many families use multiple（多样的）small electrical tools at the same time, which unknowingly（无意地）increases the total power waste.
Knowing these hidden mistakes is the first step to change. If we can correct these small errors in daily life, we can cut down a lot of unnecessary power use without affecting our normal life.
21. What is the main idea of the passage
A. New electrical devices are too expensive for ordinary families.
B. Charging devices all night is the only way to keep them working.

Power engineers play an important role in keeping electricity supply（供应）steady for our homes and cities. Their daily work is not easy, as they need to ensure everyone can use electricity safely and smoothly.
Every morning, power engineers check the power lines and stations first. They look for any broken parts or hidden dangers to stop accidents before they happen. In the daytime, they answer calls from communities and fix electrical problems in time, such as damaged wires or socket failures.
When there is a storm or heavy wind, they still have to work outdoors. They climb up the poles to repair power lines quickly, so that people won’t be left without power for too long.
They also teach people about electrical safety and energy-saving tips in communities. They believe that everyone’s effort can make the power use more reasonable and the city safer. Their hard work keeps the lights on for every family.
25. What is the writer’s purpose of writing this passage
A. To tell people how to become a good power engineer

C. They only work during the daytime and rest at night.
D. Their work has nothing to do with people’s daily life.
（C）From Ancient Wonder to Modern Necessity
In ancient times, people only knew electricity as a natural wonder. It was just lightning in the sky. They were afraid of it and never thought it could be used in daily life. It took hundreds of years for humans to turn this natural magic into a necessary tool for modern life.
In the 17th century, scientists began to do research on electricity seriously. They found small ways to produce static（静电的）electricity and studied its basic rules. By the 19th century, people built the first real power stations and started to supply electricity to cities.
At first, electricity was only used for lighting. Later, more electrical appliances were invented, and electricity became necessary for cooking, working and studying. Today, we depend on electricity for nearly everything, from smartphones to high-speed trains.
The development of electricity has completely changed human life. It has turned a natural wonder that people once feared into a key power supporting our modern society.
29. What does the underlined word “steady” probably mean

C. Safe and continuous D. Expensive and rare
30. When did people start to build the first real power stations
A. In the 1600s B. In the 2000s
C. In the 1900s D. In the 1800s
31. Why did ancient people feel afraid of electricity
A. Because they only saw it as lightning in the sky.
B. Because they used it to light their houses every day.
C. Because it could help them cook food and keep warm.
D. Because they knew how to make it in large amounts.
32. What can we learn from the development of electricity
A. Electricity has become a useless tool in modern times.
B. People still fear electricity and never use it widely.
C. Human wisdom turns natural electricity into daily necessity.
D. The first use of electricity was for cooking and working.
（D）Community Low-Carbon Electricity Plan
Our community started a low-carbon electricity plan last month to make everyone use energy in a greener way. All the residents（住户）joined in the activity and tried their best to cut down power waste.
The community gave out leaflets（传单）to tell people about energy-saving skills. Volunteers also went door to door to help old people check their electrical appliances and replace the old ones with energy-saving ones.
We held a sharing meeting to let residents talk about their energy-saving stories. Many people shared useful tips, like using solar-powered lamps in the yard and turning off all appliances before sleeping.
After one month, the community’s total power use dropped a lot. The plan not only saves electricity but also makes residents know the importance of protecting the environment. It was such a successful activity that we plan to continue it.
33. What did the community do to help old residents

A Renewable Energy Popularization Activity
Our school held a renewable energy popularization（普及）activity last Friday to help students learn about clean power and wise electricity use. All Grade 7 students joined in this educational event and had a deep understanding of green energy.
In the morning, a science expert gave a speech to introduce three main kinds of renewable energy. He explained that hydropower uses water flow, wind power relies on natural wind, and solar power collects sunlight. All of them produce no pollution and can be reused continuously（持续不断地）.
In the afternoon, we visited the energy exhibition in the school hall. There were models of wind turbines and solar panels, and we could watch videos to learn how these energy forms are turned into electricity. Some groups also designed creative posters to call on everyone to save power.
After the activity, we realized that using renewable energy is key to protecting the earth. We decided to take small actions in daily life, such as turning off appliances in time and telling others about the importance of green power.
46. Why did the school hold the renewable energy popularization activity

My Special Day Without Electricity
Last weekend, our science teacher asked us to spend a whole day without electricity. I thought it would be easy at first.
However, life became really hard without power. I couldn’t use any electrical appliances. I had to read books by natural light and hand-wash my clothes, which took me a long time. In the evening, we sat in the dark with candles. I could neither watch TV nor chat online.
The quiet night made me think a lot. This special day taught me how important electricity is to our life. From now on, I will save electricity in daily life and encourage others to develop a low-carbon habit.
