The World Meat Free Day for 2017 falls on 12, June, but what would actually happen if the whole world suddenly went vegetarian(素食的) permanently?

     If vegetarianism were accepted by everyone by 2050, the world would have about seven million fewer deaths every year. No meat would lower the chances of some diseases or even some cancers and so save the world 2-3% global GDP in medical bills. Food-related emissions would drop by around 60%. This would be due to getting rid of red meat which come from methane (甲烷) producing livestock (家畜) — from people's diets. Turning former pastures (牧场) into native habitats and forests would slow climate change and bring back lost biodiversity, including some animals which were previously pushed out or killed in order to keep cattle.

    However, farmers in the developing world could really suffer. Arid and semi-arid lands can only be used to raise animals as there's no or little water in these places, such as the Sahel land strip in Africa next to the Sahara; nomadic (游牧的) groups that keep livestock there would be forced to settle permanently and lose their cultural identities if there were no more meat. Losing meat also means that we also lose traditions. There's no more Christmas turkey. We would need to replace meat with nutritional substitutes, in particular for the world's estimated two billion-plus unhealthy or weak people for lack of nutrients. Animal products contain more nutrients per calorie than staples like grains and rice.

    Everybody currently engaged in the livestock industry would need to be retrained for a new career. This could be in agriculture, reforestation or producing bioenergy. Failing to provide career alternatives could lead to mass unemployment and social problems, particularly in traditionally rural communities.

    University Room Regulations

    The following items are approved for use in residential (住宿的) rooms: electric blankets, hair dryers, personal computers, radios, televisions and DVD players. Items that are not allowed in student rooms include: candles, ceiling fans, fireworks, waterbeds, sun lamps and wireless routers. Please note that any prohibited items will be taken away by the Office of Residence Life.

    Access to Residential Rooms

    Students are provided with a combination (组合密码) for their room door locks upon check-in. Do not share your room door lock combination with anyone. The Office of Residence Life may change the door lock combination at any time at the expense of the resident if it is found that the student has shared the combination with others. The fee is $25 to change a room combination.

    Cooking Policy

    Students living in buildings that have kitchens are only permitted to cook in the kitchen. Students must clean up after cooking. This is not the responsibility of housekeeping staff. Kitchens that are not kept clean may be closed for use. With the exception of using a small microwave oven (微波炉) to heat food, students are not permitted to cook in their rooms.

    Pet Policy

    No pets except fish are permitted in student rooms. Students who are found with pets, whether visiting or owned by the student, are subject to an initial fine of $100 and a continuing fine of $50 a day per pet. Students receive written notice when the fine goes into effect. If, one week from the date of written notice, the pet is not removed, the student is referred to the Student Court.

    Quiet Hours

    Residential buildings must maintain an atmosphere that supports the academic mission of the University. Minimum quiet hours in all campus residences are 11:00 pm to 8:00 am Sunday through Thursday. Quiet hours on Friday and Saturday nights are 1:00 am to 8:00 am. Students who violate quiet hours are subject to a fine of $25.

    Jack Ma's net worth increased $2.8bn overnight as Alibaba forecast sales growth that topped every analyst's estimate, despite the fact that China's economy is slowing down.

    Mr. Ma, aged 52 this year, is now the richest person in Asia and 14^th wealthiest in the world, according to the Bloomberg Billionaires Index. His net worth has climbed $8.5bn this year to $（4）8bn.

    The latest surge came after China's largest e-commerce company forecast 45 to 49 percent revenue(收入) growth in the year ending March, demonstrating how investments beyond online shopping are paying off. Shares in Alibaba, where Mr. Ma is chairman, rose 13 percent to a record high.

    Alibaba and Tencent, which dominate online shopping and social media, respectively have ventured(冒险) deeper into new areas from cloud computing services to streaming music and video as the country's economy slows. Alibaba is capturing more digital advertising spending by incorporating(合并) social elements such as video in its shopping sites.

    Alibaba is holding meetings with investors this week. On Friday, the former English teacher said he wasn't going to discuss corporate forecasts. He took the stage instead to describe how his company had become effectively the world's 22^nd largest economy—just after Argentina—in terms of transaction(交易) by never fearing to think big. Mr. Ma, who said Alibaba revises 10-year plans annually, foresaw the company becoming the fifth-largest eventually by 2036 by serving a burgeoning Chinese middle classes, taking advantage of global trade and making use of its valuable data.

    Ma's comments about the evolution of data-driven technology echoed Masayoshi Son, Chairman of Japan's SoftBank. SoftBank—Alibaba's largest shareholder—has invested billions in companies such as ARM with the intention of staking out a leading position in the future Internet of Things.

    “The Internet of Things is going to be big because in the past, machines drink electricity,” Mr. Ma told investors. “In the next 20 years, machines will drink data. In the future, no company, no country, no business can survive without data.”

    I look around and can't recognize where I am. It seems familiar but distant. I see my friends gather by a stage where music is playing and I run over. As I begin running towards them, they become further and further away. I keep calling them, but no one hears me. I start hearing a distant alarm-like sound and I am transported away. I woke up in a daze sitting in my bed.

    “Oh, it was only a dream,” I said to myself. I have always had vivid and intense dreams. It feels like I haven't even slept because I have been living out my dreams during my sleep.

    Today, dreaming is being studied even more than ever. Some say that dreams are how your receptors make sense of random thoughts while you sleep. Some say that you can't dream of a face you have never seen before, so everyone you see in your dreams you have at least laid eyes on at one time or another.

    Other people think dreams are ways of expressing stress or internal feelings you may be experiencing. A lot of people say that they have dreams about being chased.

    A common interpretation of the “being chased” dream is that you are feeling threatened. Some dream interpretation websites say you should try to reflect on what or who is chasing you to get a better idea of what is making you feel this way.

    Another dream that is often experienced is flying. This dream has a much more positive interpretation, which is that you are feeling free or have broken out of a bad situation such as a relationship turned sour or a job you hate.

Unfortunately, you may forget half of your dream within five minutes of waking up and within 10 minutes, you usually forget 90 percent of it.

    Dreamologists, people who devote time to the study and interpretation of dreams, suggest if you want to try to remember and study your dreams you should keep a journal beside your bed and write down what you dreamt as soon as you wake up so you can reflect on it later.

    My children are perfect. All four of them. Perfect and beautiful and clever. I bet yours are, too. Except, of course, they are not. In reality, my children and yours are likely to be reasonably average in terms of looks, behavior, intelligence and charm. That's why it is called average. Your belief in your child being special is more probably a biological thing than a fact.

    A loved one, particularly a loved child, is edited as we observe them. Other people's children are spoiled; ours are spirited. Theirs are naughty; ours are confident.

    This is all natural and even touching when not taken too far. However, it is one thing feeding this idea to ourselves but feeding it to our children may be a little less desirable. We have the idea that — unlike my parents' generation — we should build our children's self-respect as high as we can. Therefore, their random scribble (胡写乱画) is up there with Picasso, their C-minus is an unfortunate oversight on the part of the teacher, and the fact that no one wants to be friends with them is because they are particularly clever or sensitive.

    Children see through this kind of thing very quickly and ignore their parents' praises as a matter of course. As they grow up, they sense that the wider world judges them differently. This leads to a – hopefully gentle – cynicism (猜忌) about anything their parents tell them about their achievements. Perhaps that is OK — but I'm not sure if it is good for them to have the parental praise so overlooked.

    If parents were a little harsher sometimes, this could have two positive effects — first, when praise came, it would be more likely to be believed and, second, it would fit in rather more accurately with the picture of reality that the child is forming in their heads.

    A lot of pressure is put on children who are told they are beautiful, special and perfect. Because then, where is there to go? Only downwards. They become too much aware of their status in your eyes, and a danger must be that they fear failing you. To be over-praised by your parents is the counter side of being criticized all the time. Both can have negative consequences.

    It is important to give your children the freedom to be flawed (缺点) — to know that it's OK to be imperfect, and that, in fact, we often love people for their flaws — perfect people (whom we can only imagine, as they do not exist) are easy to respect, but hard to love.

    Now I am nearly 60, my main insight is that I am much less special than I once believed. This knowledge has actually been helpful in leading a more well-balanced life.

    I certainly wouldn't like to go back to attitudes that my parents, particularly my father, held, that to praise the child was to "spoil them" or make them bigheaded. However, the history of families is like the history of everything else — the story of overreactions. We praise our children to the skies, partly because we think it makes them feel good, but also because it makes us feel good. And perhaps it is more the latter than the former.

    Too much love can be as big a burden as a shortage of it. My advice is to limit your praise. Then every piece of praise will count, rather than being just ignored.

The urgency and importance of Covid-19 over (he past year have driven almost everything else from most leaders5 minds. But since the vaccine is kicking in, Britain's government is once again beginning to think about the things that will matter later. Next week, it is expected to publish a 'plan for growth" to boost productivity, with innovation at its centre.

The world may be on the point of a technological boom with life sciences, at which Britain excels. Innovation is crucial to productivity, but on this front Britain's performance has lagged behind its competitors' in recent years. Its low spending on Research and Development (R&D) argues for a boost. Those who attributed the financial failure in the 1970s to the insufficiency of research funds may regard this as a threat to economic growth. Promoting innovation can quickly (um into an exercise in picking winners - or, as is more often the case, losers.

A second danger is that policy agendas get mixed up. The government has promised to "level up" poorer areas of the country, so deprived towns arc campaigning for more money for their universities. But trying to boost innovation by sending money to weak institutions is likely to make our leading universities lose their advantages, thus producing average ideas that could have been remarkable. Britain's research-funding system has always been elitist(精英主义的). It should stay that way.

The government's first move in boosting innovation was the announcement of a plan for an Advanced Research and Invention Agency (ARIA). ARlA's purpose is to fund high-risk, high-reward research. But money is not all that mailers. The successful translation of life science research into treatments during the pandemic suggests some inexpensive measures that can also make a difference.

One is to speed up governmental processes. The rapidity with which Britain's medical regulator moved during the pandemic is one reason why the vaccine rollout is racing through the population. Urgency is not unique lo pandemics. Getting things done quickly can make an investment worthwhile and determine where a businessman chooses as a base.

Another useful measure the government should use is its unique ability to overcome barriers. At the beginning of the pandemic. Covid-19 researchers were unable to gain access to different strands of health service data. The government eased restrictions on existing data and allowed researchers to ask people who had tested positive tor Covid-19 to join trials. Both were crucial to the effort.

A last principle is the value of connections between the government and the private sector. Kate Bingham, a venture capitalist who led the vaccine-purchase effort, understood how to deal with drug companies. Many of the civil servants working with her had commercial experience. The governments closeness to business during the pandemic has been criticized. But without it, the vaccine effort would not have succeeded.

Innovation took human beings from caves to computers. Good education, a welcoming immigration policy and a friendly business environment will do most to tend it. But a new sensible principles can help keep the flame burning.
