    A total of 34 Chinese cities with a combined population of nearly 300 million took park in a pet adoption day at the weekend, promoting the adoption of rescued stray (流浪的)animals.

    The live broadcast of China Pet Adoption Day events in Shanghai, Beijing, Chengdu, Guangzhou, Hangzhou, Nanjin, Qingdao, Tianjin and Xi'an was watched by 562,000 people.

    From Urumqi in the far northwest to Fuzhou on the southeast coast, people gathered to raise awareness of animal care and to help stray find loving homes.

    Sun Quanhui, manager and senior adviser of World Animal Protection, said, “Planet Earth is not only home to humanity but also a home that we share with other animals. It is mankind's duty and important to treat animals kindly in a civilized society.”

    As China's population becomes richer, pet ownership has increased rapidly, but problems, such as pet abandonment and cruelty, are also growing.

    In recent years, more and more adoption events have taken place all over the country, which indicates an awakening of the Chinese public consciousness to animal protection.

    “Adopting a pet instead of buying one has been gaining a wider acceptance.”

    American Edward Dumpe, who has been working on designs for stray animal shelters in Beijing, said, “It surely sounds super sweet and I have no doubt that it must have been the result of great efforts.”

    “I think it is a good step in the right direction, and should be taken as evidence that Chinese society is becoming more aware of stray animals who should be taken care of and treated with respect.”

    In real life, “Rabbit-eating Carrot” is fashion designer who has created clothes embroidered(刺绣)with slogans(口号)such has “Please adopt a pet” and images of her cats, with all earnings going to the Qiming Small Animal Protection Center in Sichuan Province.

    “I didn't know that there were events like this in China. This is fantastic. Impressive.” Said George Philippe, a french living in Beijing and father of two, at an event in the capital.

    Antarctica's ice white environment is going green and facing other unexpected threats. Scientists say that as temperatures go up in the polar area, invading (入侵) plants and insects, including the flies, cause a major threat.

More and more of these invaders, in the form of larvae(幼虫) or seeds, are surviving in coastal areas around the South Pole, where the temperature has risen by more than 3℃ over the past three decades. Glaciers have melted, exposing more land which has been occupied by mosses that have been found to be growing more quickly and thickly than ever before—providing potential green homes for invaders.

    “The common house flies are a perfect example of the problem the Antarctic now faces from invading species,” said Dominic Hodgson of the British Antarctic Survey. “It comes in on ships, where it exists in kitchens and then at bases on the continent. It now has an increasing chance of surviving in the Antarctic as it warms up, and that is a worry. Insects like the house flies carry bacteria that could have a deadly effect on native lifeforms.”

    The Antarctic has several native species of insects. Together with its native mosses these are now coming under increased threat from three major sources: visiting scientists increasing numbers of tourists and global warming. However, it is global warming that is the main driver of the greening of Antarctica.

    In 2015, more than 38, 000 tourists visited Antarctica. “These tourists are often very careful about not leaving waste or having mud. But they could carry seeds or larvae on their boots when they set foot on the Antarctic, “ said Hodgson.

    More and more invasive insects and plants have been found on the Antarctic and have required removal. “The insects and plants that are native to Antarctica have survived there for thousands of years,” said Hodgson, “We have got to act now if we want to save the environment.”

    When we have troubles we turn to our family. But what would we do if we lost our family? I want to share with you a touching film about an Indian child who loses his loved ones.

    The main character in the 2016 Australian film Lion is a child named Saroo. When he is 6 years old, he follows his brother Guddu to a job, but gets lost. Saroo ends up in a new city and is adopted by a kind Australian family.

    However, one day Saroo is reminded of his original family. He knows immediately that he must find out as much about them as he can, so he racks his brains (绞尽脑汁)for all that he can remember.

    Lion is the most moving film that I have ever seen. When I saw the young Saroo trying to help his brother while they worked on a construction site at such a young age, I was amazed.

    In today's society，the poor are always looked down upon. But I saw in the eyes of young Saroo great courage and kindness that made me think differently. He has great qualities that help him survive in the strange city where he finds himself.

    When Saroo sees that people are kind he rewards them with the sweetest smiles and loves them with all of his heart. Saroo's goodness, I believe, allows him to live a happy life with his Australian foster (收养)family.

    It is unbelievably hard for Saroo to reunite with his original family. He can't even remember the name of his hometown. It takes him days to find the real one. In fact, he has to go through every alternative (供选择的东西)he can find on Google Maps.

I'm deeply impressed by Saroo's determination. It is why, when I saw the movie, I cried at the moment when he finally found his mother.

    Lion is full of moving and impressive details. There are so many that I can only mention a few of them here. But what stands out most to me is Saroo's commitment (投身)to finding his original family，and the fact that his search doesn't stop him from loving his foster family.

    I want to recommend this film to everyone. See it and you'll come to understand so much about family and love.

    Bullying(霸凌) can take a variety of forms, from the verbal to the physical as well as indirect forms, such as being excluded from social groups. Bullying is clearly unpleasant, and can make the child experiencing it feel unworthy and depressed. In extreme cases it can even lead to suicide, though this is thankfully rare.

    Until recently, not much was known about the topic, and little help was available to teachers to deal with bullying. Perhaps as a consequence, schools would often deny the problem. There is no bullying at this school' has been a common answer if asked, almost certainly untrue. Fortunately more schools are now saying: “There is not much bullying here, but when it occurs we have a clear policy for dealing with it.” Three factors are involved in this change. First is an awareness of the severity of the problem. Second, a number of resources to help tackle bullying have become available in Britain. For example, the Scottish Council for Research in Education produced a package of materials, Action Against Bullying, circulated to all schools in England and Wales as well as in Scotland. In Ireland, Guidelines on Countering Bullying Behaviour in Post-Primary Schools was published, too. Third, there is evidence that these materials work, and that schools can achieve something.

    Evidence suggests that a key step is to develop a policy on bullying, saying clearly what bullying means, and giving explicit guidelines on what will be done if it occurs, what records will be kept, who will be informed and what punishments will be employed. The policy should be developed through consultation over a period of time. Pupils, parents and staff should feel they have been involved in the policy. Other actions can be taken to back up the policy. There are ways of dealing with the topic through the curriculum, using video, drama and literature. But curriculum work alone may only have short-term effects; it should be an addition to policy work. There are also ways of working with individual pupils, or in small groups. Work in the playground is important, too. One helpful step is to train lunchtime supervisors to distinguish bullying from playful fighting, and help them break up conflicts. Another possibility is to improve the playground environment, so that pupils are less likely to be led into bullying from boredom or frustration.

    With these developments, schools can expect that at least the most serious kinds of bullying can largely be prevented. The more effort is put in and the wider the whole school is involved, the more substantial the results are likely to be. The reduction in bullying and the consequent improvement in pupil happiness is surely a worthwhile objective.

    American and British people both speak English of course. But sometimes it does not seem like the same language. In fact, there are some important differences between British English and American English.

    First of all, they sound very different. Often, Americans don't say each word separately. They say several words together. Americans may say "I dunno" instead of "I don't know". Or they may say "Whaddaya say?" instead of "What do you say?" However, the British are more careful in their speech. They usually say all the words and keep them separate.

    Sound is not the only difference between British English and American English. Words sometimes have different meanings too. Some American words are never used in England. The same thing is true of some British words in America. For example, the vocabulary for cars and driving is very different. Americans drive trucks, but in England people drive lorries.

    Many expressions are also different in the two countries. In England，if you are going to telephone your friends, you "phone them up". In America, you "give them a call". When you are saying goodbye in England you might say "Cheerio!" In America you might say "See you later."

    There're also some differences in grammar. For example, Americans usually use the helping verb "do" when they ask a question. They say "Do you have a storybook?" But the British often leave out the helping verb. They say "Have you a storybook?"

    All these differences can be confusing if you are learning English. But most languages are like this. Languages change over time. When people live in separate places, the languages change in different ways. This is what has happened to English. It can also happen to other languages, such as French. Many people in Canada speak French, but their French is very different from the French of France.
