People lie all the time, but depending on how skilled they are, it can be difficult to determine when someone is lying to you. Do you know how to recognize the signs that someone is lying to you? Some of the signs are obvious while others are more subliminal(难以察觉的), but there are ways to catch someone in a lie, you just need to know what they are. {#blank#}1{#/blank#}

1） Liars make false eye contact.

    A person who is lying to you won't make eye contact with you or they make too much eye contact. If a person is lying they may feel you are watching him and he will look down at the floor or away from your eyes. Some people try to stare you in the face deliberately. {#blank#}2{#/blank#}

2）Liars avoid using contractions(缩略形式)

    The liar will say “I did NOT notice that.” instead of “I didn't notice that.”{#blank#}3{#/blank#} Usually it ends up making the story a lot less believable.

3）Unnatural Body Language.

    Liars often feel uneasy, turn away from the person to whom they are speaking, blink(眨眼) rapidly, smile less and have pitch changes in their tone of voice. They may cross their arms which is a sign of being “closed” or trying not to reveal too much information. {#blank#}4{#/blank#} They could touch parts of their face, an ear or a nose or play with keys or another item that they have in their hand.

4）Liars provide additional information without being asked for it

    {#blank#}5{#/blank#}The result is the more complicated the story is, the less believable it will be. You will have the feeling that nothing could be further from the truth.

A. This is an attempt by the liar to be absolutely clear what they mean.

B. Here are some easy ways to recognize liars and catch lies.

C. Sometimes people look unnatural when they are lying

    How did people in ancient China change their luck? Most of them would take the exam, Keju, which began during the Sui Dynasty and lasted for 1,300 years before it was ended in the Qing Dynasty.

    Keju, the early “gaokao”, played a very important role in choosing qualified persons to work for the king.

    The Keju exams were mainly based on classical literature(文学) and philo- sophy. Poetry was very important in earlier Keju exams, and later Keju focused more on writing.

    All candidates had to write an article explaining ideas from those books, which was called Eight Part Essay. Two sentences were required at the start of the article, about the main idea of the title, which was called “to clear the topic”. The exams also focused on more practical matters.  

    Most candidates in ancient China had to go a long way to the capital city for the exam. As transportation in ancient times was not developed, they usually went to the capital on foot, and some took several months to reach the capital.

    The exam was held once every three years and it was made up of four levels: the county examination, provincial examination, academy examination and palace examination. Candidates had to first pass one level in order to take part in the next level. Each examination would take from one to three days to finish, and they were locked in a small room and received cold meals.

    On the exam day, candidates had to first go through safety check. They had to let their hair loose so that it could be checked and their trouser legs, shoes and socks, even bottoms were also checked.

    Are you interested in hi-tech products? Here are some that you might find at the market pretty soon.

    CX-1

    Tired of dragging your bag through busy airports? Then you might want to consider CX-1. The smart suitcase uses facial recognizing software to follow its owner as he / she is checking in or heading to the gate. Though CX-1 can only move at a speed of up to seven miles per hour, a tiny tool enables owners to keep track of the suitcase's location. It is expected to be sold on the market by late 2018.

    Aibo

    Sony's latest version of the Aibo robotic dog is almost as fun as the real thing—but much less work. The pet dog can recognize its owner, obey several commands, and even recall the behavior that pleases its master the most. Aibo can also learn new tricks, take photographs, and over time, develop its own unique personality.

    Forpheus

    Forpheus, an “athletic” robot developed by Japanese technology company Omron. It teaches users how to play ping-pong. The 10-feet-tall machine uses a camera and artificial intelligence to track the ball's speed and can predict the ball's direction correctly. The smart Forpheus can also quickly test its player's abilities and adjust the playing level, making the game fun.

    Black Box VR

    Though many people determine to go to the gym once a week, few reach their goal. Black Box VR wants to change that by turning hard exercise into fun video games. Using it, gym users will find themselves fighting enemies, including big creatures—all while getting exercise.

    In an unmanned supermarket, a customer waits to pay. With the use of advanced digital payment technology, including biological recognition and in-depth learning, the man leaves in a minute. There's no cashier in the store. At a large university, students use a hand-scanning machine that authorizes their entry into the gym. Those people are using "smart machines" which identify people by their physical characteristics. These new devices use fingers, hands, faces, eyes and voices. Some machines may even use smells. This new technology, called biometrics, gets information from parts of the body.

    In the past, biometric machines were used mainly in government agencies or in prisons. But now that the cost of the technology is lower, these machines are starting to be used everywhere, from border services to schools.

    Some people, however, are concerned that these machines will mean the destruction of personal privacy. They worry that the machines will get personal information about them, know it seems like these machines are invading our privacy, but actually, biometric machines help to protect it," says Jay Tarkett, who works at a company that develops the machines, "They can be used instead of passwords on a computer, for example. They can also identify criminals at airports. So, really, they help to promote public safety, and all the information stored is kept confidential by the machine itself."

    Some people don't like the idea of using fingerprints because they associate them with criminals, and feel like they are being accused of something, In addition, they don't work for some people, such as bricklayers, who wear down their fingerprints. Yet, face recognition does work well because the subject doesn't really have to do anything, To cash a check at a bank, for example, the customer has to do nothing more than look at a machine similar to an automatic teller. If the face matches the picture kept on file, the customer gets the money with no problems, The need to carry identification with you from place to place, then, would all but cease. It has been found that the hand scan works well ill the college gym. Before this machine was used, students at the college entered the gym using cards similar to credit cards. The problem was that students often lost or forgot their cards. With the hand-scanning machine, however, the problem was solved right away.

    But the machines are still new, and there can be problems. For example, voice recognition works on the phone, but it is not precise, and can be tricked. Another constraint(限制)we notice；, with machines that use face recognition in particular, is that they can be fooled if people color their hair or gain a lot of weight. However, this particular problem may be solved by a new type of technology that scans a person's iris, the colored part of the eye. It can even identify the person from a few feet away, recognizing a customer as he or she approaches the ATM.

    The pupils of Grangetown High have been busy getting to know their newest and tallest classmate — a 7-meter-tall giraffe outside their school.

    The giraffe is a huge sculpture (雕像). The school's headmaster noticed it in an artist's garden as he drove past one day, and thought it would be perfect for his school. “I knew everyone would love it," he said, "because our basketball team is known as the Grangetown Giraffes, and they wear giraffes on their shirts. So I asked them to write to the artist, asking how much it would cost to buy the giraffe. He was very kind and got it ready to deliver (递送) in six weeks — all for nothing! It was expected to arrive one Sunday morning, so that the pupils would see it when they got to school on Monday — at that time they had no idea that we were getting it."

    The artist, Tom Bennett was a university professor of chemistry before he retired in 2012 and only took up metalwork a couple of years ago. "I've always drawn pictures," he said. I can even remember doing it on my first day at school — I drew a horse. I wanted it to be the best horse picture ever, but I don't think I succeeded."Tom's first metalwork was a bicycle on which he and his wife could go cycling together, “It was the most uncomfortable bike ever created," he said, "so I gave up making bicycles and went into sculpture instead."

    Meanwhile the pupils at Grangetown High are very happy with their new classmate. "We're going to hold a competition to give it a proper name," said one girl. "Everyone likes the expression on its face, so perhaps that will give us some ideas."
