It's true that quite a few most respected scientific authorities have confirmed that the world is becoming hotter and hotter. There^'s also strong evidence that humans are contributing to the warming. Countless recent reports have proved the same thing. For instance, a 2010 summary about the climate science by the Royal Society noted that: The global warming over the last half - century has been caused mainly by human activity.”

    You may not believe that humans could change the planet's climate, but the basic science is well understood. Each year, billions of tons of greenhouse gases are released into the atmosphere because of human activity. As has been known for years, these gases hold heat that would otherwise escape to space, wrapping the planet in an invisible blanket.

    Of course, the earth's climate has always been changing due to “natural” factors such as volcanic eruption or changes in solar, or cycles concerning the Earth's going around the sun. According to the scientific research, however, the warming observed by now matches the pattern of warming we would expect from a build - up of greenhouse gas in the atmosphere - not the warming we would expect from other possible causes.

    Even if scientists did discover another reasonable explanation for the warming recorded so far, that would give birth to a difficult question. As Robert Henson puts it: “If some newly discovered factor is to blame for the climate change, then why aren't carbon dioxide and the other greenhouse gases producing the warming that basic physics tells us they should be?”

    The only way to prove with 100% certainty that humans are responsible for global warming would be to run an experiment with two identical Earths-one with human influence and one without. That obviously isn't possible, and so most scientists are careful not to state human influence as an absolute certainty.

    The annual World Economic Forum (经济论坛) took place in Davos, Switzerland, in Jan 23 -26, 2018. What did Chinese entrepreneurs (企业家) speak in the forum? Are there some quotable quotes for you?

    Jack Ma, founder and executive chairman of Alibaba Group

“I think globalization cannot be stopped — no one can stop globalization, no one can stop trade. If trade stops, the world stops. Trade is the way to dissolve the war not cause the war,”said Ma in Davos, “Google, Facebook, Amazon and Alibaba we are the luckiest companies of this century. But we have the responsibility to have a good heart, and do something good.”

    Richard Liu, founder and chief executive officer of JD

    “Business is not only a way to make money but also a way to contribute yourself, to help people,” Liu said in a speech in Davos.”How can we face the fractured (分化的) world? That's the topics of the Davos this year. I think a very important thing in business is cooperation. If we can unite, work together, (if) we work very closely, I think we can bring more hope to the people and we can build more trust between the people, countries and companies and partners,” he said.

    Jane Sun, CEO of Ctrip

    “Tourism is a sunrise industry. Since I entered Ctrip, every year there are new comers, which, first of all, shows that tourism is booming.” Sun told Sina.com in Davos. “We invested heavily in ABC. A refers to AI, B is big data, and C is cloud computing. As we continue to expand overseas, these three will be very good weapons for us. So we think those mean opportunity,” she said.

    Hu Xiaoming, president of Aliyun

    “In 2018, people will see the development in various countries more closely connected with cloud computing. More manufacturing enterprises and financial institutions will start to use 'cloud', and cloud computing will increase the efficiency of technology and finance,” Hu told Xinhua in Davos.

Pride and Prejudice for the Modern Woman

    Let us imagine how Pride and Prejudice, Jane Austen's most famous work, might be updated, 200 years on. Austen's popularity is rooted in her intelligence. But today she would certainly have had a very different life, as would her characters(角色). Here's my own suggestion…

    It is a truth finally and universally acknowledged that a single woman with brains deserves to have equal opportunities to men, however disadvantaged she may feel by sexism.

    "My dear husband," said his hopeful wife one day," have you heard that the local store, standing empty for so long, is taken over by a bright young businesswoman?"

    Her dull and indifferent (漠不关心的) husband replied that he had not. "But it is, it is," she replied excitedly. Mr. Dull-Husband made no reply.

    "Don't you want to know her plans?" she cried with some impatience.

    "Well, clearly you think it matters to your silly little head, so I'd better listen."

    "Well, my dear, the rumour (传言) is that she has already set up a string of successful businesses in northern England, though how a woman can know anything about that is beyond me". She will move in herself next month." "What is her name?" "Bingley."

    "Is she married or single?"

    "What a question! And none of your business. But her coming will be a fine thing for our five boys." "How so? How can it possibly affect them?"

    "My dear love; those lazy boys need something to wake them up. There are bound to be jobs going."

    "Is that her point in settling here? Surely as a woman she has simply taken a fancy to the place."

    "Nonsense, my love, how little you've noticed the world has changed. She's got a first-rate degree and some sort of business qualification, I'm told. She surely needs one of our boys! Perhaps you might give her a call."

    "Me? No. Perhaps you can take an interest. You still have your looks, after all. She may even offer you a job." "Oh, that's not likely. These new chances belong to the younger generation. But now you mention it, I think I'll go along all the same."

    And Mrs Bennet went along. That was 10 years ago. She is now managing director of a FTSE-listed company.

    It would remain the case, of course, that Mrs Bennet would be one of very few women on the company board, that her salary would be lower than her male colleagues, her bonus of a more "female" dimension(方面) and her lifespan (年限) among the city's business leaders shorter than theirs. Still, she'd no doubt have enjoyed Davos(达沃斯经济论坛)—and might even have hobnobbed (攀谈) with influential figures.

Don't Drop the Ball

    Drop prevention risk assessment is really important. Everyone knows objects get dropped on work sites – there's nothing radical about that. In Australia, mining has the third highest fatality rate of any industry (4.4 fatalities per 100,000 workers in 2015), and in less well-documented areas like India the fatality rate is even higher. A lot of these fatalities come from dropped objects. It's worth trying to address this and work out just how big the risk is and where it comes from. At the end of the day, safety should be a priority in any industry and it should come as no surprise that addressing safety issues early can actually save money, long-term, for companies. It doesn't look good for a mining company if people are getting injured and equipment damaged from falling objects.

    The risks from dropped objects come from all sorts of areas; it's not just a matter of dropped tools. We're talking about sites characterized by a lot of activities, where all sorts of things can come loose or fall, whether its light fittings or objects like rocks falling off transporting belts. The risks are largely personal but are also financial: if a piece of equipment gets damaged it will need replacing. That's a pretty strong inspiration for companies to address these risks. In terms of frequency, here in Australia we're looking at around 18% of compensation claims coming from workers being hit by moving objects, but those are just the claims – the frequency is likely higher. Around 28% of deaths and injuries come from such incidents, too. As I said earlier, that's just Australia; some industries don't keep statistics, but I wouldn't be surprised to find other countries report comparable rates. That's a lot of accidents that could be prevented with adequate safety measures.

    It's important to take an active approach. It's a lot easier and cheaper to address these risks during the installation or maintenance phases by adding barriers to the inside of guard railings on walkways and transporting systems and adding nets to fixed devices. There are safety mechanisms available, but it's up to the companies to install them. It is a lot more efficient to add barriers right from the start rather than waiting for an accident and then thinking, "Should we be safer?", when they should have reduced these risks from the start.

    Everything about nuclear energy seems terrifically big: the cost, construction and decommissioning—and the fears of something going badly wrong.

    The future, however may well be much smaller. Dozens of companies are working on a new generation of reactors that, they promise, can deliver nuclear power at lower cost and reduced risk.

    These small-scale plants will on average generate between 50MW and 300MW of power compared with the 1,000MW-plus from a conventional reactor. They will draw on modular manufacturing techniques that will reduce construction risk, which has plagued larger-scale projects. Supporters believe these advanced modular reactors (AMRs)—most of which will not be commercial until the 2030s—are critical if atomic power is to compete against the rapidly falling costs of solar and wind.

    "The physics hasn't changed. It's about much cleverer design that offers much-needed flexibility in terms of operation," said Tim Stone, long-term industry adviser and chairman of Nuclear risk Insurers, which insures nuclear sites in the UK.

    Since the Fukushima meltdown in Japan in 2011, safety fears have threatened nuclear power. But the biggest obstacle today is economic. In western Europe, just three plants are under construction: in the UK at Hinkley point in Somerset; at Flamanville in France; and at Olkiluoto in Finland. All involve the European Pressurized Reactor technology of EDF that will be used at Hinkley Point. All are running years late and over budget. In the US, the first two nuclear projects under way for the past 30 years are also blowing through cost estimates.

    The UK, which opened the world's first commercial nuclear reactor in 1956, is one of the few western nations committed to renewing its ageing fleet to ensure energy security and meet tough carbon reduction targets. It is seen as a proving ground, by many in the industry, of nuclear power's ability to restore confidence.

    However, the country's agreement with EDF to build two units at Hinkley Point—which together will generate 3.2GW of electricity—has come under severe criticism over its cost. The government is looking at different funding models but said it still sees nuclear power as vital to the country's future energy mix. Small reactors, it believes, have the potential to generate much-needed power from the 2030s.

    A nuclear sector deal, unveiled last month, promised up to ￡56m in funding for research and development into AMRs and attracted interest of start-ups from around the world. The government hopes the funding will give the UK a lead in the global race to develop these technologies, helping to provide energy security while also creating a multibillion-dollar export market for British engineering companies.

A Lesson Plan from Life Planning Education: A Youth Development Program

    Purpose: To learn about body language and how to use body language.

    Materials (材料): Cards; container

    Time: 25-35 minutes

    Planning Notes:

    ·Write the words below on cards:

    angry disappointed shy afraid sad happy nervous excited bored

    ·Place the cards in the container so volunteers can draw them out one at a time.

    Steps:

    First make sure that all volunteers know what body language means (expressing feelings through body movement and facial expressions). Go over the following instructions:

    ·I'll need at least 9 volunteers to play a game similar to charades (猜词游戏).

    ·The first volunteer will draw a card with a feeling written on it and act out the feeling without using words.

    ·The rest of the group will guess what feeling is being communicated. Once someone correctly guesses the feeling, the next person in line will draw a card and act out what is written on it, again without words.

    ·The game will continue until there are no more cards or until time is up.

    At last, end the activity using the discussion points below:

    ·Can you give examples of when someone's body language communicated a different message from what he/she actually skid?

    ·Sometimes one person is offended (冒犯) by another's body language. How can you work to keep that from happening? Answers may include: be honest and direct; match your nonverbal messages to your verbal ones; be aware of (清楚) cultural attitudes toward different kinds of body language.
