Last Sunday, I adopted the baby dog from an animal shelter. I was impressed by its lovely appearance for the first time I saw it. I brought it home but decided to build a warm home for it. Due to my tight budget, I had to make a cage for it by me. First, I watched various video relevant to making cages. Then I reach the market to buy the materials. After that, I had the materials tying together with strings. About three hours later, the cage set up. I put the dog into the cage. It wagged its tail happy. Although the cage looked strange, I felt satisfying with what I had done.

5 . 72 hours in Beijing

Traveling to China is no longer a luxury for many foreign passport holders. The Chinese government has permitted a 72-hour visa free policy that offers access to visitors from 53 countries including the US, France and Austria. Let’s start with the capital of China, Beijing. Here’s a pick of the best in Beijing.

Your trip to Beijing isn’t really complete without seeing one of the “New Seven Wonders of the World” — the Great Wall of China. The Mutianyu section of the Great Wall is by far the most well-preserved of all. Taking a one-hour bus ride, Mutianyu would be your ideal location for a half-day of hiking away from the large crowds in the city. Also, the authorities have allowed tourists to paint graffiti on a specific section of the Great Wall since 2014. The Great Wall was designated (把……定名为) a UNESCO World Heritage site in 1987.

Located in northwestern Beijing, the Summer Palace is by far the city’s most well-preserved royal park. With its huge lake and hilltop views, the palace offers you a pastoral escape into the landscape of traditional Chinese paintings. The Summer Palace was added to the UNESCO World Heritage List in 1998.

This would be on the top of my list! Named after the 798 factory that was built in the 1950s, the art zone is home to various galleries, design studios, art exhibition spaces, fashionable shops and bars. You could easily spend half your day wandering around the complex, feeling the contrast of the present and the past.

While in Beijing, apart from trying the city’s best-known Peking duck, the Sichuan provincial restaurant is one of places where you can enjoy regional delicious food. It offers one of China’s eight great cuisines, Sichuan Cuisine, which ranges from Mapo tofu to spicy chicken.

6 . Bertie knew there was something in the wind. His mother had been sad in recent days, not sick, just strangely sad. The lion had just lain down beside him, his head warm on Bertie’s feet, when Father cleared his throat and began, “You’ll soon be eight, Bertie. A boy needs a proper education. We’ve found the right place for you, a school near Salisbury in England.”

His heart filled with a terrible fear, all Bertie could think of was his white lion. “But the lion,” he cried, “What about the lion?”

“I’m afraid there’s something else I have to tell you,” his father said. Looking across at Bertie’s mother, he took a deep breath. Then he told Bertie he had met a circus owner from France, who was over in Africa looking for lions to buy. He would come to their farm in a few days.

“No! You can’t send him to a circus!” said Bertie. “He’ll be shut up behind bars. I promised him he never would be. And they will come to see him and laugh at him. He’d rather die. Any animal would!” But as he looked across the table at them, he knew their minds were quite made up.

Bertie felt completely betrayed. He waited until he heard his father’s deep breathing next door. With his white lion at his heels, he crept downstairs in his pyjamas, took down his father’s rifle from the rack and stepped out into the night. He ran and ran till his legs could run no more. As the sun came up over the grassland, he climbed to the top of a hill and sat down, his arms round the lion’s neck. The time had come. “Be wild now,” he whispered. “You’ve got to be wild. Don’t ever come home. All my life I’ll think of you, I promise I will.” He buried his head in the lion’s neck. Then, Bertie clambered down off the hill and walked away.

When he looked back, the lion was still sitting there watching him; but then he stood up, yawned, stretched, and sprang down after him. Bertie shouted at him, but he kept coming. He threw sticks. He threw stones. Nothing worked.

There was only one thing left to do. Tears filling his eyes and his mouth, he lifted the rifle to his shoulder and fired over the lion’s head.

Contrary to     1     some people might assume, evidence     2     (show) that sharks seldom attack humans. There are three types of shark attacks. In the main type, the shark attacks you because it mistakes you     3     a fish,     4     when it tastes human flesh, it decides     5     (give) up and swims away. In the second type, the shark     6     (push) you with     7     nose to find out if you are fit to be eaten, and then bites you     8     it thinks you are. In the third type, the shark waits for you to swim by, and then attacks you all of     9     sudden. The last two types of attack more often result in the     10     (die) of humans.

8 . People have been wondering why elephants do not develop cancer even though they have lifespans(寿命)that are similar to humans, living for around 50 to 70 years.

Now scientists believe they know why. A team at the University of Chicago, US has found that elephants carry a large number of genes that stop tumors(肿瘤)developing. To be precise, they found 20 copies of an anti-tumor gene called TP53 in elephants. Most other species, including humans, only carry one copy.

According to the research, the extra copies of the gene improved the animal’s sensitivity to DNA damage, which lets the cells quickly kill themselves when damaged before they can go on to form deadly tumors.

“An increased risk of developing cancer has stood in the way of the evolution of large body sizes in many animals,” the study author Dr Vincent Lynch told The Guardian. If every living cell has the same chance of becoming cancerous(癌变的),large creatures with a long lifespan like whales and elephants should have a greater risk of developing cancer than humans and mice. But across species, the risk of cancer does not show a connection with body mass.

This phenomenon was found by Oxford University scientist Richard Peto in the 1970s and later named “Peto’s paradox(悖论)”. Biologists believe it results from larger animals using protection that many smaller animals do not. In the elephant’s case, the making of TP53 is nature’s way of keeping this species alive.

The study also found that when the same genes were brought to life in mice, they had the same cancer resistance as elephants. This means researchers could use the discovery to develop new treatments that can help stop cancers spreading or even developing in the first place.

“Nature has already figured out how to prevent cancer,” said Joshua Schiffman, a biologist at the School of Medicine, University of Utah, US. “It’s up to us to learn how different animals deal with the problem so that we can use those strategies to prevent cancer in people.”

9 . The Silk Road is arguably the most famous long-distance trade route of the ancient world. This passage connected Europe in the West with China in the East, and allowed the exchange of goods, technology, and ideas between the two civilizations. Although merchants could make huge profits travelling the road, it was not without risk.

The main Silk Road started in Chang’an (known today as Xi’an), the early Han capital. Travelers commencing their journey from this city could take a northern route that would take them across China’s northwestern provinces. After this, they would face the Gobi Desert, arguably the greatest danger of the Silk Road.

The Gobi Desert, the largest desert in Asia, consists mainly of rocky, hard earth. This feature made it easier for traders to travel across, compared to sandy deserts like the neighboring Taklamakan Desert. Like other deserts, the Gobi Desert is dry and hot, and therefore the biggest challenge travelers faced was obtaining enough water for themselves as well as for their camels.

So, rest stops were created along the route, allowing travelers to rest, eat and drink. These places also promoted the exchange of goods, and even ideas, amongst the travelers who stopped there. Usually, the rest stops were placed within a day’s journey of each other. In this way, travelers could avoid spending too much time in the desert, which would make them targets for robbers, another danger of the Silk Road.

Once through the Gobi Desert, travelers would continue their journey into Iran, Turkey, and finally Europe. While this part of the journey may have been less dangerous, it is not entirely without its perils (风险).
