Mahatma Gandhi once said, “The greatness of a nation can be judged by the way its animals are treated.”

    There is no doubt that China is a country with high moral values. It has never attacked another country, has one of the lowest rates of violent crimes and is deeply concerned with the social and economic welfare of its people.

    But when it comes to animal rights, China may well fail Gandhi test. There are no laws against the killing of dogs and the sale of dog meat in China. In fact the serving of dog meat in Chinese restaurants has increased in recent years.

    People who eat dog meat argue that dogs have been eaten in China for thousand of years and dog meat has “health benefits”.

    There is, however, a strong argument against waiting dogs .Recently, some Chinese animal rights activists stopped a truck carrying about 500 dogs and saved the poor animals from being sold and served as food in restaurants. These people that dogs are not meant to be eaten but loved.

    Jack threw the papers on my desk. “Next time you want to change anything, ask me first,” he said. I had changed a long sentence and corrected its grammar — something I thought I was paid to do.

    Several days later, he made me angry again. I went to his office, prepared to lose my job if need be, but not before I let the man know how I felt. “What?” he said nervously. Suddenly I knew what I had to do. “Jack, the way you've been treating me is wrong. And it's wrong for me to allow it to continue,” I said. “I want to make you a promise. I will be a friend.” The next day I brought some cakes to Jack's office. Every time I saw Jack in the hall, I smiled at him. After all, that's what friends do.

    One year after our talk, I was told that I had breast cancer (乳腺癌). When I was in hospital, my friends tried to find the right words to say, but no one could. The last day of my hospital stay, the door opened and Jack walked over to my bed. “Tulips (郁金香),” he placed some bulbs (球茎) beside me and said, “If you plant them when you get home, you'll be there to see them when they come up.” Tears filled my eyes. In a moment when I prayed for just the right words, a man with few words said the right thing. After all, that's what friends do. Now, I have seen those tulips push through the soil every spring for over ten years.

Do you like spicy food?

    What's your opinion on spicy food? Some people cannot handle even the smallest amount of chili-red pepper-in their dinner while others can't get enough of it.

    Scientists have long been puzzled by why some people love chili while others loathe it. Plenty of research has been done on the subject, dating as far back as the 1970s. Previous results showed that a love of chili is related to childhood experiences, and cultural influences affect our taste buds too. But the latest study has found that a person's love of spicy food may be linked to his or her personality more than anything else, CBC News reported.

    'We have always assumed that liking drives intake-we eat what we like and we like what we eat. But no one has actually directly bothered to connect these personality traits with intake of chili peppers,' said Professor John Hayes from Pennsylvania State University, who led the study.

    But before you look at the study, you should first know that “spicy” is not a taste, unlike sour, sweet, bitter and salty. It is, in fact, a burning sensation that you feel on the surface of your tongue. This got scientists thinking that maybe a love of spicy food is brought about by people's longing for thrill, something they usually get from watching action movies or riding a roller coaster.

    In the study, 97 participants, both male and female, were asked to fill out questionnaires about certain traits of their personality, for example, whether they like new experiences or tend to avoid risks. They were then given a glass of water with capsaicin, the plant chemical that makes a chili burn, mixed into it.

    By comparing the answers to the questionnaire and what participants said they felt about the spicy water, researchers found that those who tended to enjoy action movies or take risks were about six times more likely to enjoy the spicy water.

    Interestingly, we used to believe that the reason some people can withstand spicy food is that their tongues have become less sensitive to it. However, this latest study has found otherwise. “It's not that it doesn't burn as badly, it's that you actually learn to like the burn,” Hayes explained.

    In many big cities, a lot of old people keep birds, cats, dogs and other animals in their houses. These animals are friendly to the old people and never leave them. So the old people love them and see them as their good friends or families.

    It's not difficult to keep these lovely animals at home. But you have to take them to animal hospitals to give them needles (注射), so they won't get ill or they will make people ill. Now there are lots of animal food stores here and there. People can buy good animal food for their animals there. Old people can buy animal food on the phone or on the Internet. But it's a little more expensive.

    Sometimes it's kind of dirty and dangerous to keep animals. They sometimes look dirty and smell terrible and can be dangerous. For example, an old woman in Shanghai lost her life on the street for her pet dog.

    Maybe old people in big cities have many reasons to keep these nice and clever animals. They may feel lonely when their children leave. And these pets can be their great helpers. They are their good friends and help them in many things.

    In England, some food companies across the whole country have been told to carry out urgent (紧急的) tests on all beef products. Do you know why? That's because some food companies used horse meat to make beef products.

    There are some examples about the horse meat matter. In January, 2013, in a number of UK supermarkets, frozen hamburgers were found to have traces of horse meat in them. Some frozen beef products made by food company FINDUS were found to contain horse meat. All of the beef products made by this company have been removed from sale.

    The government said that there's nothing to suggest any health risk from the products. Food minister David Heath said people should not throw away frozen meat products and carry on eating meat. The government will tell people not to eat meat if the meat is not safe.

    Food safety has been an important matter all over the world. More and more countries plan to take some useful measures to ensure the safety of food.

    British chemist David Evans has become an overnight celebrity on Chinese social media. His chemistry experiments have attracted over 2 million followers in just a few months. Evans is a chemistry professor at the Beijing University of Chemical Technology. The 60-year-old always wears a white lab coat, a pair of safety goggles (护目镜), and smiles often. Some web users say he looks just like the “grandpa of KFC”.

    Evans has posted videos of various experiments. His most popular experiments have attracted millions of hits on video-sharing apps. Excited children's cheers and shouts can be heard in his videos. “I hope my experiments can arouse people's interest in science,” he says.

    Evans has been interested in China since childhood. In the early 1970s, before the reform and opening-up, he viewed it as a “country full of mysteries”. He first visited the Chinese mainland in 1987 to attend a chemistry conference in Nanjing, Jiangsu Province. He quit his job in the United Kingdom and moved to Beijing in 1996. Many of his friends thought he was crazy. But Evans says they just saw China's challenges but not its potential.

    Since 2011, Evans has turned to the Internet to popularize science. He learned short-video apps are also popular in small cities and rural areas. And he realized this enables him to reach more students, who lack opportunities to perform fun experiments. But even a one-minute video requires a considerable amount of work. Still, he thinks it's worth it to fulfill his responsibility to popularize science.

    His experiments always fill schools' lecture halls with laughter. Some viewers call him “a Harry Potter-like magician”, but he disagrees. “A magician never tells the secrets behind his tricks, but a scientist always gives an explanation.” He sees himself as a teacher. He performs experiments to spread knowledge, inspire thinking, remove misunderstandings and show that science can create change. Evans says he looks forward to more “chemical reactions” with China.
