Have you ever been ill? When you are ill, your body becomes hot, and there are pains all over your body. You must be unhappy because of it. You don't want to work. You stay in bed feeling sad.

    What makes us ill? It's germs. Germs are everywhere. They are very small and you can't find them with your eyes, but you can see them with a microscope (显微镜). They are very, very small and there could be hundreds of them on a very small thing.

    Germs are always found in dirty water. When we look at dirty water under the microscope, we can see them in it. So your father and mother will not let you drink dirty water.

    Germs aren't found only in water. They are found in the air and dust (灰尘). If you cut your finger, and if some of the dust from the floor goes into the cut, some of the germs will go into your finger. Your finger will become big and red, and you will have much pain in it. Sometimes the germs will go into all of your body, and you will have pain everywhere.

It seems that environmental protection is the {#blank#}1{#/blank#}(任务) of adults. Can teenagers do their parts in it? Zheng Huan, a 19-year-old girl from Sichuan gave her answer.

"Today, climate change has{#blank#}2{#/blank#}(造成) great damage to the environment around us," Zheng said. "It's time for us to make a {#blank#}3{#/blank#}(不同之处) by ourselves. She set up an organization. They worked with game {#blank#}4{#/blank#}(公司), artists and programmers and make climate change a thing that could be seen, felt and dealt with.

Zheng has been working on a game called Guardians of Earth. Players take pictures of different things in nature to get points. One teenager said, "I {#blank#}5{#/blank#}(很少) paid attention to plants or animals. But now they have all become {#blank#}6{#/blank#}(生动的) and meaningful to me because now I know them."

{#blank#}7{#/blank#}(另一个) project is digital artworks about climate change. Last year, lots of artists were {#blank#}8{#/blank#}(邀请) to create works based on the book AI 2041. The book talks about how AI will have {#blank#}9{#/blank#}(影响) on the environment in the future. "Paintings are a direct form of art and online paintings can reach more people very {#blank#}10{#/blank#}(迅速地)," Zheng said. "I want to communicate the climate change in beautiful ways to increase people's understanding of nature," she added.

My name's Daming. I have some photos which show some of {#blank#}1{#/blank#} experiences. They were{#blank#}2{#/blank#} with my first camera at the age of 

10. At the age of 14, I got {#blank#}3{#/blank#} camera as a gift. After that, I took many photos of people and buildings with it. Among these photos, you can see my sister Meimei{#blank#}4{#/blank#} in front of the Diwang Building with a big smile on her face. The Diwang Building has a(n){#blank#}5{#/blank#} of 303 meters. It is one of the tallest buildings in Guangxi. 

Later this camera was {#blank#}6{#/blank#} . I was very sad about that {#blank#}7{#/blank#} I didn't give up my hobby. I learned photography through reading and saved money by working as a waiter at weekends. Finally, I had a third camera. It worked well in {#blank#}8{#/blank#} light, and I took a lot of photos with it. In my pictures, you{#blank#}9{#/blank#} saw high buildings as before. Instead, I paid more {#blank#}10{#/blank#} to the color and character of the country. Soon I won the first prize in some photo competitions. My friends told me that I could become an artist. 

A young man went to an expert on gems(宝石)and wanted to learn from him. The expert shook his head He worried that young men wouldn't have the patience to learn. In his opinion, they were always in a hurry. 

The young man asked the expert many times to let him have a try. Finally the expert said, "Be here tomorrow. "

The next morning, the expert put a jade(翡翠)stone in the man's hand and told him to hold it. The expert then went about his work, cutting, weighing and setting gems. The man sat and waited excitedly. The following morning the expert again placed the jade stone in the man's hand and told him to hold it. On the third, fourth, and fifth day the expert repeated the action. 

On the sixth day the young man still had to hold the jade stone, but he could no longer stand the silence. "Sir, "he asked, "when am I going to learn something?"

"You will learn. "the expert replied. 

Several more days went by. The man became more and more impatient. However, when the expert placed a stone in his hand one morning, the young man shouted without looking at it, "This is not the same jade stone!" "You have begun to learn, "the expert said with a smile. 

"Let's go home," Liam said to his little sister, Flora, after their art class one Saturday morning. We' re late for 1 ."

 The night before, it had snowed hard. They had difficulty walking to their cozy home on Adelaide Street, passing through an empty building site. Suddenly, Liam heard a loud thud(砰的一声). He 2 only to see that Flora was gone. His sister had fallen into a deep hole. "Help!" she cried.

 Liam looked around, but no one was in sight.

"Climb up the sides!" Liam 3 . His sister tried climbing up the hole, but failed. Then, he saw a huge tree nearby. He found the 4 tree branch and broke it off. He showed it to Flora."Get hold of the tree branch!" Liam pleaded.

 She 5 the branch, but it wasn't close enough, "I can't reach it!" she responded.

 Liam saw a store in the distance and decided to get 6 . It was far, so he needed7 to mark(标记) his way.

 He went through his backpack and 8 some paint cans from his art class. I could use those paints to mark my way, Liam thought.

 Liam walked difficultly to the store with many red marks behind him. He looked 9 the window. The lights were off, and there was nothing on all the shelves. A Closed sign was on the door. Feeling upset, he walked back to Flora 10 .

 Suddenly, he had a wonderful 11 . He used his scarf, jacket, and hat to make a long rope(绳子). Liam 12 the rope into the hole and leaned down(俯下身), so Flora could catch it.

 Liam leaned down 13 Flora caught the rope. He then 14 pulled her up. Liam smiled.

 They hugged and after walking for what felt like forever, their cozy red 15 was finally in sight..
