Here I want to tell you some informationabout water.

    Water covers most of our planet. People canfind it in oceans, lakes and rivers, and under the ground. Water moves in theenvironment by evaporation, condensation, and precipitation. The warm Sun helpswater change into vapour and rise up into the sky. It is evaporation. Thevapour in the air forms clouds in the sky. It is condensation. When the cloudsget heavy enough, the water falls back to the ground as rain or snow. This isprecipitation.

    Ocean water has too much salt in it. Muchof the water travels far over the land. When it travels over the land, thewater picks up salt from the rocks and soil. About 97.5% of the Earth's wateris salty water. It is expensive to take salt out of the water.

    All people need clean water. They need itfor drinking, for cooking, and for bathing. Some people in a village in SouthAmerica did not have clean water. Their water was full of oil and dirty things.People there got sick when they drank the water. Other people heard about theproblem. They sent empty water tanks (储水池) tothe village. Rainwater fell into the tanks. Now the people in that village havethe clean water.

When a fire happens, what should you do? You may be 1 , but you must keep calm(平静的).

Call 119 for help. Tell them2 the fire is. Then try to tell others about the fire. You can3 or use the fire alarm (报警器).

Next, you must get out4 . Don't try to take away things. Go out5 the window if you are on the ground floor.

6 you can't get out of the burning (燃着的) building, just stay with others in one room. 7 the door. Put clothes around it closely. Then open the window and call for 8 . Don't use a lift (电梯). The lift may stop at any time. You have to run 9 the stairs (楼梯).You can take a piece of 10 cloth (布) with you. Put it over your mouth. The water in it can protect you from the smoke and fire.

Drones（无人机）are like planes, but come in many shapes and sizes. They have no pilots and are controlled from outside the drones. During these years, they have been used to attack（进攻）enemies or moved goods（货品）in dangerous areas. 

Now small drones are part of people's lives. For example, people use drones to take photos or make videos. Besides, a drone delivery（n.投递）service has proved（证明）successful. 

Online store JD can use drones to deliver small packages（包裹）. It has built several drone stations so that it can load（装载）and deliver（v. 投递）its packages. 

Drones have made our shopping experience different. We can order a new coat in the early morning and it will be delivered before we finish breakfast. 

Bizzby Sky, a UK company, has created a delivery service for small goods. Open a smart phone app, enter your address, set a time and pay enough money for the delivery service. Then in minutes, a drone will do tasks for you. 

However, any drone company needs government permission（允许）to fly its drones in many countries. We believe we will see more and more drones with goods fly in the sky very soon. 

Drinking a cup of milk tea with friends? That's "city". Visiting the Great Wall of China? Very "city". Riding a bike down Shanghai's Anfu Road? Quite "city".

If you don't get it, let me explain it to you. The popularity of "City bu city?" has risen on the Internet these days. You can use it to describe whether someone, or something is urban (都市的) and modern or not.

"City bu city?" was first used by American blogger Paul Mike Ashton. He has lived in Shanghai with his sister for years. His name on the Internet is "Bao Bao Xiong". He likes sharing travel experiences in China on Douyin and Xiaohongshu. Ashton became popular after he shared a video of him asking his sister "City bu city?" on the Great Wall.

The word "city" itself has now taken on a new meaning as an adjective (形容词). Ashton himself says that it describes something that happens in the city, but it can also be "something that gives you a great love for life".

In recent years, a large number of foreign tourists like Ashton have been sharing their experiences of visiting China online. Topics about travelling in China are becoming more and more popular. Now people around the world can learn more about different places of modern China and Chinese way of life. And all of these are shown in a more emotional (感性的), friendly and natural way.
