3．　　The Adventures of Tom Sawyer is one of the great works by Mark Twain. The book is so interesting. Even today, it is quite popular among kids. Although I am in my thirties, the book remains one of my favorites. After re-reading the book recently, I have learned an important lesson from Tom Sawyer.
　　In our daily lives, we are often given some boring or tiring tasks. What's in your mind when your mom tells you to clean the floor? Have you ever wanted to complain (抱怨)? I think most people have.
　　Tom Sawyer, however, thought "differently" when he was given a boring task. One Saturday morning, Aunt Polly told Tom to paint the fence (篱笆). Tom's friend Ben Rogers happened to walk past. Instead of complaining, Tom told Ben that he felt "excited" about the task. "Only one in a thousand — maybe even two thousand — boys can do this!" Tom said.
　　Tom's words made Ben interested in the task. He even gave Tom his apple so that he could have a chance to paint the fence. If Tom had thought about nothing but complaining, he would have had a bad day painting the fence.
　　This story teaches me a valuable lesson: complaining is useless. The next time you are given a boring or tiring task, don't complain. Unlike what happens in the story of Tom Sawyer, it is unlikely that someone will come and do the work for you. However, without complaining, you'll feel better and perhaps even do a better job!

4．　　Otters (水獭) are cute water animals. These days, keeping otters as pets is getting popular. In Japan, some "otter cafés (咖啡馆)" are open for business. People can pay to play with the otters there and to take photos with them. In Indonesia, people go swimming with their pet otters and take funny videos. These photos and videos posted online have interested more people to buy otters as pets.
　　However, these enjoyable photos and videos hide the damage (损害) that the online trade is doing to otters. In fact, wild otters are facing many threats — they have long been hunted (猎杀) for their coats; in some places, fishermen have been killing otters in order to stop them from eating fish; and now, the online pet trade has become another big problem for otters.
　　In the wild, baby otters usually stay with their mothers during their first year of life. According to a report, 70% of the otters sold online are under one year old. These baby otters have been stolen from their mothers. When they are kept as pets by humans, they do not live full and natural lives.
　　Otters are very social. They live in family groups of up to 15 in the wild. Keeping an otter as a pet can make it very sad and lonely. These animals also need enough space to swim. Their owners' bathtubs (浴缸) or pools are nowhere near as large as the bodies of water in the wild.
　　On the other hand, otters simply don't make good pets. They have a very special fishy smell. If they are kept indoors, they will leave a lot of waste around the house. This would make the smell even more unpleasant. Besides, when otters are unhappy, they will make loud noises and even attack (攻击) people. If a person is hurt by an otter, he or she needs to go to hospital at once.
　　So, we should stop the otter pet trade and never share photos and videos about them online.

5．　　The human population on Earth grows larger each year. As a result, (1)      . Because of climate change (气候变化), growing more food is becoming even more difficult.
　　When farmers tried to grow more food in the past, they would use farming methods that weren't always healthy for the environment. To solve this problem, (2)      . They spent several years talking to farmers. They wanted to see what problems farmers were having and how these problems could be solved. (3)      . These special robots move around on farms and collect information about crops (庄稼). They can take pictures of plants, track (追踪) each plant's growth and measure (测量) its size.
　　In the past, though farmers did have information about the weather and the earth, they couldn't track each plant. (4)      .
　　By collecting information about plants, the robots can help farmers make predictions (预测) about how their plants will grow. (5)      . For example, if the robots find out which plants get sick, farmers can quickly throw them away before they are about to influence nearby plants. With the help of these robots, farmers can take better care of the plants in need.

7．　　I went to Beijing to study Chinese last year. I was (1)       about all the chances to better my language skills, walk on the Great Wall, and most of all, eat real Chinese food! I (2)       remember my first jianbing, jiaozi and Peking duck. Each of them was amazing in its own way.
　　I knew that real Chinese food would be different from the Chinese food I had eaten in the USA. I couldn't wait to try all the (3)       dishes that came up in my research about Chinese food. One of my favorites turned out to be hotpot (火锅).
　　My first-ever hotpot experience in Old Beijing was (4)      . As a first-timer, I was moved by the waiters' (5)       and their warmth of welcome. They tried their best to introduce all of the oils and spices (调味香料) to me.
　　Looking around, I found that everyone had their own favorite sauce combinations (酱料组合), ingredients and styles (食材和风格). Some would carefully (6)       their ingredients into the hotpot one after another. Others would impatiently put whole plates into the bubbling (冒泡的) oil. You can learn a lot from the (7)       people eat hotpot.
　　When I went back to the USA, I (8)       to prepare a hotpot meal for my family. It allowed me to not only share the culture that I had learned about, but also offer others a chance to (9)       China like I had. It's amazing that (10)       could bring so much to life!

8．　　The Netherlands needs thousands of new houses because the country (1)      (have) a growing population. Anyway, it may not have to build all those houses. Some of (2)      (they) can be printed.
　　(3)      (recent), the government has been working together with a university and some building companies (公司) to build houses that are fully 3D-printed. As volunteers, an old couple has become the first people in Europe to move into such (4)       house.
　　With two (5)      (bedroom) and a big living room, the house was built layer (层) by layer, using a huge 3D printer and special cement (水泥). After being printed out, the house (6)      (carry) by a truck to the building site, and a roof (屋顶) and windows were later added. It took around 120 hours (7)      (finish)this 3D-printed house. Usually, it takes about one or two years to build a house in the (8)      (tradition) way.
　　The couple will live (9)       this house for six months, with a monthly pay of 800 euros (欧元). The cost seems a little bit high, but they think it is much cheaper (10)       living in the hotel.

9．　　When people say Chinese culture, we often think of paper cutting. (1)Paper cutting is an art form with a long history in China. Traditional paper-cuts were first put on windows for decoration (装饰). That is why paper-cuts are also called "window flowers". Most paper-cuts are made of red paper, because red means good luck in Chinese culture. Today, people use paper-cuts to decorate not only windows, but also doors and other furniture (家具). (2)Sometimes, people use them as gifts.
　　Paper-cuts are popular because of their expressions of good wishes and hopes. During the Spring Festival, for example, many people put up paper-cuts of the Chinese character (汉字) "Fu" upside down on the door. (3)他们希望这会给他们带来好运。 At wedding ceremonies (婚礼), you can always see paper-cuts of the character "Xi". It means that the new couple can enjoy happiness together.
　　Paper cutting has developed into different styles in different parts of China. (4)Paper-cuts from the north of China usually have interesting shapes. In southern China, people prefer paper-cuts with the themes (主题) of flowers, fruit, birds and fish.
　　(5)学习剪纸非常容易。 With a piece of paper and a knife or a pair of scissors, you can try to make your own paper-cuts. Although paper cutting is easy to start with, you need a lot of practice and imagination to become really good at it.
