London is such a wonderful city. It is very large. The Thames River runs 1the city from west to east. So the city has 2 parts: the South and the North. In the North, there are important buildings, shops, big parks and interesting places. The3in London is good. In winter it is not very cold and in summer it is not very hot 4 the city is near the sea. People say London is a foggy city and it often rains. It is true. Last year, when I 5 in London, I met one of the thickest fogs in years. You could hardly see your hand in front of your face. Cars and buses moved 6 with their lights on. When evening fell, the weather got even 7. The fog was as thick as milk.8 the buses and cars stopped. I happened 9 an important meeting on the other side of the town, but it was impossible to find a car. I had to get there 10.

    Alice had an argument with her best friend Judy last Sunday. She thought 1 was really difficult and wanted to copy Judy's homework. But Judy refused. They didn't talk to each other for a few days. Alice didn't know 2 to face her math problem and she wondered if she could get on well with her friend again.

    Yesterday afternoon, she saw a cool boy 3 the violin happily by the road when she was walking home from school. The violin sounded so nice. 4 Alice didn't know what music he was playing, it made her feel better. After he finished the music, Alice walked over to him and said, "Thank you 5 your beautiful music. It gets me out of the really bad mood(心情)." Then she took out some 6 and gave it to him. To her surprise, the boy asked her to take the money back. He explained that he wasn't making money by playing the violin. He just wanted to 7 others. He hoped that the wonderful music could make people relaxed and happy. What a 8 boy he was. Then Alice told him about her trouble.

    He said, "You should learn to smile even if you are in difficulty. Listening to music is helpful. So why not listen to music as 9 as possible? Never lose heart! Believe in your friend! She has her reason. Believe in 10! Everything will go well!

    Hearing these words, Alice went home with a smile. She believed she could make it.

A short video series called Escape from the British Museum(《逃出大英博物馆》) was quite a hit(成功). It tells a story of how a Chinese cultural relic(文物) ran away from the British Museum and found its way back to China.

In the short video series, a girl played the role of an ancient Chinese jade teapot(玉壶). She escaped from the British Museum and ended up in the street in London. She came across a young man there. He was a Chinese news reporter. She thought that the young man was her family, so she asked him to take her back to China.

Why did the two main characters decide to make the short video series? They saw someone's comment(评论) online and drew their inspiration(获得灵感) from the comment. Then, they went to the UK and spent months researching and preparing. It took them around three months to finish the video series. Although the video series is less than 30 minutes, it touched millions of Chinese people's hearts.

The short video series is not only fun but also educational. It tells us Chinese that it's time to bring the long-lost Chinese cultural relics home. China lost a lot of cultural relics overseas. There are more than 23,000 pieces of Chinese cultural relics in the British Museum. There is a long way to go to bring them home.

"Boys and girls，are you ready for the test？" Our teacher Ms. Kelly asks. 

"Yeah!" We answer happily. A test is 1 to us. 

I answer quickly until I read the last one， "Do you know the 2 in our school？What is her first name？" 

Of course，I 3 the cleaner. She is thin and wears an orange jacket every day. We always see her clean the restroom （厕所），4 how can I know her name？I 5 talk to her. 

After class，I give my paper to Ms. Kelly，leaving the 6 question empty （空白的）. I feel sad because I never （从不） say hi to her. 

On my way to the restroom，I see her 7 jacket. I run to her. 

"Hello!Hmm. . . Thank you for giving 8 a clean school. " 

In our life，we meet many people. All are 9 and all you do is to smile and say hello. I can never forget this 10 . I will never forget her name-Dora. 

During the Mid-Autumn Festival, do you eat mooncakes? Do you know that the history of mooncakes is related to two wars?

In the Tang Dynasty, there was an emperor (皇帝) named Li Shimin. Once, his army won a war and returned {#blank#}1{#/blank#} the Mid-Autumn Day. While Li was celebrating with his army, a Tibetan trader (吐蕃商人) gave him some round{#blank#}2{#/blank#} (cake) as a gift. Li was happy and{#blank#}3{#/blank#} (send) these cakes to his soldiers. {#blank#}4{#/blank#} that, these round cakes became popular. Many people ate {#blank#}5{#/blank#}(they) during the Mid-Autumn Festival. Later, the cakes were named as "mooncakes". 

Zhu Yuanzhang was the first emperor of the Ming Dynasty. He ended the Yuan Dynasty through an uprising (起义). When he organized the uprising, it was difficult to send messages {#blank#}6{#/blank#}(secret). One of his friends came up with{#blank#}7{#/blank#}idea. He gave mooncakes with a note hidden inside of them to other people. The note read, "Uprising on the fifteenth night of the {#blank#}8{#/blank#}(eight) lunar (农历的) month." After the {#blank#}9{#/blank#} (success) uprising, Zhu gave mooncakes as gifts to his people. Since then, it {#blank#}10{#/blank#} (be) a custom to eat mooncakes during the Mid-Autumn Festival.

How tall is a tree? Usually trees in parks are over a few metres tall. But in Xizang, a fir(冷杉) is about 83. 4m tall! It is the tallest tree in China until 2022. The tree is about 380 years old. It is still growing well. 

Chinese scientists measured it in August. How did they measure such a tall tree? Scientists climbed up to the top of the tree. It took them about seven to eight hours to get to the top. They put down a 100-metre-long metal tape(金属卷尺) to the ground. Scientists measured this tree with a drone(无人机) in May. They said it was 83. 2m at that time. This time, they measured the tree more carefully and found it was 83. 4m. 

Scientists used a drone to take photos of the tree. The drone took three to six photos every few metres. It got over 160 photos. Putting them together, scientists got a full-size photo of the tree!
