As a child, Wang Junyan never dreamed of becoming a famous person on TV. However, she is the presenter for Universe TV news programmes. She told me that{#blank#}1{#/blank#}, working hard and believing in what was true made her success. Her mother was a strong character. She worked extremely hard{#blank#}2{#/blank#}through school. Her attitude towards life will never stop influencing her thoughts and actions. After graduating from university, Junyan chose to be a journalist to help the people and the government{#blank#}3{#/blank#}and catch the guilty people. It wasn't easy but she never gave up. This{#blank#}4{#/blank#}because she won an award for her report. When asked about her secret to success,{#blank#}5{#/blank#}she told us, “Nothing that I learned from my mother has ever left me. Today when I'm looking for stories, I still feel like I am turning over stones to see what might be hiding beneath!”

    Hundreds of years ago, Charles Darwin predicted that facial expressions of emotion are {#blank#}1{#/blank#}. If you've ever seen an episode of the popular US TV drama Lie To Me, you will really understand facial expressions. The leading actor of the show, Dr. Cal Lightman has spent 20 years studying nonverbal communication and facial expressions, which allows him to point out other people's studying nonverbal communication and facial expressions which allows him to point out other people's {#blank#}2{#/blank#} and on many occasions, to be skilled at tricking in order to get the truth.

    Is there really much truth behind this science of {#blank#}3{#/blank#} human emotions through expressions? Paul Ekman, a(n) {#blank#}4{#/blank#} psychologist whose work focuses on mapping facial expressions, is Lie To Me's scientific advisor and the following are some of his explanations.

    Hand-to-face gesture indicates a lie.

    Each micro-expression is unique to {#blank#}5{#/blank#} specific emotions because the person is often unaware of doing it. But it doesn't necessarily mean that they are lying when someone uses a hand to hide part of his face. The person could be holding back information but you may better consider looking at other more important clues rather than just the simple hand-to-face gesture.

    A liar refuses eye contact.

    People look away when they are thinking carefully and considering each word before it is spoken, not just when they are {#blank#}6{#/blank#} an excuse. Oblique eyebrows are a very reliable {#blank#}7{#/blank#} of sadness and few people can make this {#blank#}8{#/blank#} expression, so it is actually never faked.

    Guilty knowledge technique is {#blank#}9{#/blank#}.

    Lightman often uses the guilty knowledge technique, mentioning something that only the guilty person will know about and show a(n) {#blank#}10{#/blank#}. This is often used in polygraph exams: "Was the person strangled, shot or stabbed to death?" Only the killer knows and is likely to respond physiologically when the actual weapon is mentioned.
