China's largest search engine Baidu has said it will make its latest artificial intelligence (AI) technology accessible to developers and businesses as part of the company's latest move into AI, big data and cloud computing.

    AI solution "Tianzhi" was launched at a cloud-computing summit held in Beijing Wednesday. It includes services in three fields: sensing technology, such as image and voice processing, machine learning, and deep learning, an advanced form of machine learning, said Zhang Yaqin, CEO of the Nasdaq-listed company, at the summit.

    Developers can access facial or voice recognition, algorithms(演算法) for data analysis and projections, and deep learning applications, Zhang said, adding that the technology could help users innovate in their sectors.

    "With more devices connected to the cloud, enterprises will use cloud computing and AI more frequently," said Wu Hequan, an academician at the Chinese Academy of Engineering, "Open AI technology can play a bigger role."

    The company also revealed a plan to invest 10 billion yuan (1.45 billion U.S. dollars) in cloud computing in the next five years and establish an innovation center, which will serve 10 million enterprises.

How to Win a Debate Competition

    Debating doesn't mean that you can end up arguing with your opponents(对手). {#blank#}1{#/blank#}．The following tips on how to win a debate will further help you out.

    1 ){#blank#}2{#/blank#}

    This is very important. If you already know the debate topic that you are going to debate on, learn as much about it as you can. Research on it and then form opinions about it. Only if you know something in and out, will you be able to talk convincingly on it.

    2 ) Be confident.

    When you are putting your point in front of your opponents as well as the audience, be sure of yourself. Along with the words, your body language, voice modulation (语调) and eye contact, will play a major part in your success in debating. {#blank#}3{#/blank#}

    3 ) Give real life examples.

    While debating, make use of very simple language, which your audience can understand very easily. Give as many real examples as you can when making a point. {#blank#}4{#/blank#}．Thus, the judges and audience will find you much more convincing.

    4 ) Be descriptive.

    To win any debate, there is something about the human mind that you should be aware of. The thing with us humans is that if we see something, we believe and remember it much more than something we merely hear! {#blank#}5{#/blank#}．Tell you point of view in such a way that they can actually "see" what you are saying. If you are somehow able to pull this off, there is no doubt that you will be the winner of the debate competition!

    Follow the tips mentioned above, and with time, you will see yourself winning over your judges and audience.

    Next time you raise an eyebrow at the views of your partner, friend, sibling （兄弟姐妹） or colleague, remember they could be helping to make you smarter. New research shows that intelligence is not fixed but can be improved throughout adulthood by family members, bright mates and intellectually challenging careers. The study challenges the commonly held belief that intelligence is fixed by the age of about 18.

    Scientific consensus suggests that intelligence is controlled by genes, with environmental factors such as schooling and nutrition playing a partial role up to this age. After this point, IQ scores become steady（稳定的）. But James Flynn, professor of political studies and psychology at the University of Otago in New Zealand, argues that people can "upgrade" their own intelligence throughout their lives. He believes intellectual stimulation（刺激）from others is important as the "brain seems to be rather like a muscle - the more you use it, the stronger it gets". However, the opposite is also true - so people sharing a home or workplace with those who are intellectually challenged risk seeing their IQ levels nosedive as a result.

    Professor Flynn analyzed US intelligence tests from the last 65 years and created new IQ "age tables". He found a bright ten-year-old with brothers and sisters of average intelligence will suffer a five to ten point IQ disadvantage compared to a similar child with equally bright brothers and sisters and special educational treatment to help pull them up.

    Professor Flynn also concluded that although genetics and early life experiences determine about 80% of intelligence, the remaining 20% is linked to lifestyle. This means that people can raise their IQ, or allow it to fall, by ten points or more. He suggested the best way to improve IQ levels is to mix with bright friends, find an intellectually challenging job and marry someone cleverer.

    Halloween is a holiday full of tricks and treats and all things frightening and fun. But what happens when you trade your sweets for a scare? The result is always healthier than candy.

    Being frightened can be good for you. Think about your favorite scary books or movies. You are scared but you just can't resist reading or watching them. Being frightened makes your brain flood with healthy chemical substances that excite your mood and release feelings of great excitement.

    When you're frightened, your body also produces a chemical called oxytocin, which helps people bond with one another. So, if you're at a haunted(闹鬼的) house with some pals, that experience can help strengthen your friendship. “Watch people walking out of a haunted house, and you'll see lots of smiles and high fives,” says Dr. Margee Kerr, a sociologist who studies fear.

    There is also some evidence that being scared can help a person manage stressful situations. Things like giving a presentation in front of your class or performing in a school play can make us fearful and anxious. But these experiences help build a sort of endurance to fear that makes us more confident. “You become more comfortable with the physical experience of fear, and so you're better able to work through it during tense situations,” Kerr explains.

    Though some haunting may be healthy, it's important to remember that people experience fear in different ways. What may be fun for one person could be too scary for another. And Kerr notes that kids younger than six and or seven can't separate real and make-believe, so seeing something frightening could have lasting, negative effects.

    It's no secret that your personal characteristics directly affect how you interact with the world-but you might be surprised at just how deep it goes. Experts think that your personality can even affect how you exercise and influence what sports are suitable for you.

    Highly Sensitive

    Highly sensitive people may be more uncomfortable with group exercise classes or team sports where they feel their every move is being observed. Additionally, they may feel more upset over an ineffective or poor workout, says researcher Elaine Aron.

For such people, individual or non-competitive activities like biking, running and hiking are ideal.

    Type A Personality

    Type A individuals often have an "all or nothing approach" to exercise. This personality type is known for sticking closely to their plan, not to mention being super competitive. However, this can cause them to stick too closely to a fitness routine, which means they might try to push past an injury.

    To get better exercise results, Type A people need to be aware that following an exercise plan too strictly may limit their progress. They should be more flexible and listen to their body, especially when they are in pain.

    Type B Personality

    This laid-back group may get too lazy about their exercise plan, which prevents them from seeing results. They are often less willing to devote enough time and energy to their fitness goals, especially if exercise is something that makes them anxious.

    Type B individuals succeed in creative and co-operative environments, so team sports and group gym classes may be perfect.

    Remember, there are plenty of ways you can adapt a fitness plan to suit your needs, regardless of your characteristics. Just keep in mind what you like.

    Do you think the United Kingdom and the United States are alike? Winston Churchill once joked that the people of Britain and the people of America are separated only by their language. Do you think that is true? The British and the Americans both speak English as the official language. However, each uses some different words. We Americans are similar to the British. After all, our country was once owned by the UK,so we have a lot in common. But there are many differences between us.

    The UK has a king or queen, and the leader of the government is the Prime Minister. The US has no kings or queens. Our leader is the President.

    Both the British and Americans use pounds and ounces, pints, quarts, and gallons. Both use miles, yards, and feet. Our money is different, though. The British use pounds and pence. Americans use dollars and cents.

    Driving in a car is very different in the UK. They drive on the left side of the road. We drive on the right. What we call the hood of the car, the British call the "bonnet". British cars run on "petrol", which we call gasoline.

    In our everyday life, we do many of the same things as the British. But we describe them differently.

    A young mother here might push a baby in a baby carriage. A British mum pushes a "pram". The British watch "telly", while we watch TV. We like to eat French fries, but the British call them "chips". Millions of Americans drink coffee, but most British prefer tea.

    So we are different in many ways. But we stay friendly anyway.
