Musk, the richest man in the world, is good at Chinese. When he was at a meeting on global food crisis（危机）, Musk quoted（引述）Cao Zhi's seven-step poem, " Pods burned to cook peas, Peas weep in the pot, Grown from same root, Why boil us so hot? "

Besides Musk, it's amazing to know that an Italian astronaut working on the International Space Station wrote on her social media, "The universe is so big and has so much stuff（事物）to watch, and it's great to see and know and drink."

Before she came to China, she had learned to speak Chinese. She quoted the Preface to the Works of Lanting《兰亭集序》because she had a good friend who was a Sinologist（汉学家）. Before the flight, her Sinologist friend suggested that she quote this line from the Preface to the Lanting Collection.

Chinese belongs to an elite（精英的）culture in European and American countries. Ordinary people in Europe and America have no interest in Chinese. They think Chinese is really too difficult for them to learn. However, in the elite circles of Europe and America, it is different. No matter in business and space, or science research. Not only the European astronauts have to learn Chinese, but also the workers of the Saudi Arabian who work closely with China. Even American astronauts need to learn Chinese ahead of time（提前）.

More and more European and American elites start to learn Chinese because the future of China's global influence will be bigger and bigger. They plan ahead and plan ahead for their children.

Learning Chinese is necessary if astronauts from around the world want to work on China's space station. This is why the Italian astronaut learned Chinese.

The goal of China's plan to land on the moon is to build a permanent base（永久基地） on the moon. Any astronaut needs to learn at least two languages, either in an American or Chinese spaceship. There is no third choice in the future. Chinese is directly connected to the career and future. Therefore, the elite of Europe and America think they really can't fit the situation if they do not learn Chinese.

People in Western countries are eating less meat these days, whether for their health or because they want to protect animals. But now they have another reason that eating less meat can help to prevent climate(气候)change to make a better environment.

Raising livestock(家畜) is bad for the environment. When animals like cows digest(消化) food, their stomachs make greenhouse gases((体),which is a major cause of global(全 球)warming.17percent of greenhouse gas emissions(排放）come from livestock farming, The New York Times reported. To raise these livestock, people have to cut down forests and turn them into farms. Forests play a key role in fighting global warming because they take in greenhouse gas. …

The study found eating less meat could cut global food—related(与食物相关的)emissions by nearly 35 percent by 2050. Eating more vegetables in the long term could cut down emissions by 63percent.

But eating less meat won't be easy. People in Western countries will need to eat 90 percent less meat than they do now, or it will have no influence on our climate.

Some say that eating insects could help. A UN report says that eating insects is healthier and better for the environment. They produce 75 percent less greenhouse gas than livestock. Some experts are creating man—made meat. People in the US might be able to buy this kind of meat in the future.

My father didn't know how to show love. He went to work every day. He often blamed (责备) me when I had made mistakes.

Once I broke my leg, my mother held me in her arms all the way to the hospital. My father pulled the car right up to the doors of the hospital. He looked really anxious (焦急的).

When I learned to ride a bike, I asked him not to leave me alone, but he said it was time. I fell and my mother ran to pick me up, but he stopped her. I was mad and I wanted to show him that I could ride it myself.

When I went to college, my mother wrote letters to me. He just sent money and a little note about how great his garden looked now because I wasn't playing football in it. Whenever I called home, he acted as he wanted to talk but always said, "Wait, Tim. I'll get your mother. "

All my life he said, "Where are you going? What time are you coming home? "Father's love is as great as a mountain, people often say. Didn't I realize his love?
