Egypt is a country in Africa. The capital of Egypt is Cairo. That is a really great city. It is the largest city in Africa. If you visit that city, you will find a very modern place with many cars, businesses, schools and homes.

About 82 million people live in Egypt. They have a rich history. Long ago, Egyptians made it the greatest place in the world. They built pyramids. These very smart people invented ways to farm.

Long ago, Egyptians were wonderful leaders who built great buildings and set up schools. They invented a special way of writing that was called hieroglyphics（象形文字）. They looked like pictures instead of alphabet letters. You will still see hieroglyphics in Egypt today. But they are not used to read and write. They are a part of history.

Egypt has a long history. It has been a leader for a long time. If you read Egypt’s history, you will know how great this country has been.

Today most Egyptians live near the banks of the Nile River. This is where the only good land to farm. It’s a great place to live in. There are other parts that are difficult to live—they are deserts. So not many people live there. About half of Egypt’s residents（当地人） live in cities. Those big cities are in the area of the Nile River. If you go to Cairo, the biggest city, you will find millions of people.

Egypt is a great county. It has a wonderful history. It will have a great future because people are working hard. They are working together to get more jobs and homes.

①Jane’s friend Amy often hides her phone. When Jane is busy looking for it, Amy will always say, “You are too careless and forgetful.” Amy always tells Jane that the clothes Jane wears are ugly and not fit for her. When Jane is angry about her words, she will say, “I say that because I am your real friend.” If you have a friend like Amy, be careful! Maybe you’re experiencing the gaslighting (煤气灯效应).

②Gaslighting is a kind of mental abuse (精神虐待) where someone blames (指责) you for something they do, making you think you’re wrong, crazy or making you even question your memory and unable to trust yourself.

③To see if you meet the problem of gaslighting, you need to learn about some signs. The most typical one is that it can make you unsure of yourself. For example, you may find it difficult to make a simple decision.

④At the same time, you may often say sorry to the abuser and find excuses for his mistakes. Even worse, you will become lonely and feel sad, scared and hopeless.

⑤Since gaslighting is bad for mental health, it is important to deal with it at once. Scientists say the best thing you can do is to leave the person who gaslights you although it can be very hard. If you are not sure what to do, please talk to someone you trust, like a parent, a teacher, or a doctor. They can help you know what to do next and how to feel better.

⑥Scientists add that keeping a secret diary and using a cell phone to record the events are also good ways. They can help you remember the things including date, place and other useful information so that you know you’re not imagining.

Have you ever ridden a bike in the sun? It might make you feel a little hot. However, riding on a cycle path（骑行小路）in a sunny area could be fun. In the town of Krommenie, you can find a special cycle path that can create energy by using the sun.

This 70-meter-long cycle path was built with solar panels（太阳能板）into it. These panels take in light from the sun’s rays. Then they use the light to create electricity, which can power street lights. The electricity can also go straight into the electrical grid（电网）to offer electricity for daily use. In the first year, this short path was creating enough energy to power one house for a whole year!

This kind of path hasn’t been widely built because scientists are still doing research to test the safety of it. They must make sure the path is strong enough for cars, buses and even trucks to drive over it. They must also make sure the path isn’t too smooth because being too smooth could be a little dangerous. Bike riders may fall easily while riding on it.

In another town called Eindhoven, you can also find a cycle path which uses solar energy to make art. It’s about 1 kilometer long. The path opened in 2014. It is made up of thousands of tiny lights. The lights take in the sun during the day and shine bright at night like stars. These lights come together like a beautiful picture. Every year, many tourists visit it and take photos there.

It’s fantastic and creative to use the sun.
