George Bernard Shaw was interested in the way people spoke. He argued that he was never{#blank#}1{#/blank#} (mistake) about a person's status. However, Professor Higgins thought a superior social position was more dependent on grammar and pronunciation. Actually, his view was only accepted by a {#blank#}2{#/blank#} (hand) of his followers. Eliza, a flower girl, was ambitious to improve herself. {#blank#}3{#/blank#} (force)to earn money herself because her family was poor, she dreamed of working in a proper flower shop. George Bernard Shaw teamed {#blank#}4{#/blank#} with Professor Higgins to help her. An English teacher {#blank#}5{#/blank#}  (hire) to give her lessons. But after her first lesson, she was {#blank#}6{#/blank#} (apparent) disappointed because the teacher was so impatient with her. Actually, Eliza didn't give it up easily. {#blank#}7{#/blank#} (look) ahead, she decided to work hard. Knowing it was impossible {#blank#}8{#/blank#} (accept) in that profession if she did not speak correct English, she asked Professor Higgins to give her lessons. Trained for several months, she set out to speak in {#blank#}9{#/blank#} more attractive accent. Shortly, she became known as “the London songbird” {#blank#}10{#/blank#} her spoken English became so pleasant.

    When was the last time that you dialed a phone number from memory? It probably depends on how long you've been using {#blank#}1{#/blank#} like a cellphone. While some generations can recall the days of memorizing phone numbers, it's possible that members of Generation Z have never had to remember a single {#blank#}2{#/blank#}. Why is this? Because smartphones offer quick and convenient ways for storing and {#blank#}3{#/blank#} information. There is no need to memorize anything. But this isn't without consequence. As digital devices develop, more and more users' heavy reliance on them may be having disabling effects." Digital dementia（失智）"is the term being used by medical professionals to identify some of these effects.

    Some professionals like Jim Kwik, an expert in memory improvement and optimal brain performance, are taking a closer look at this effect. Kwik describes digital dementia like this:"...we're {#blank#}4{#/blank#} our brains to our smart devices. We're so reliant on our smartphones that our smartphones are making us stupid. As medical studies chart the decline in memory and cognitive skills among smartphone users, a connection is made between symptoms {#blank#}5{#/blank#} with dementia."

    The seriousness of overuse becomes {#blank#}6{#/blank#} when you consider just how young smartphone users are becoming. Author and speaker Simon Sinek points out that young minds" Are not ready for it! Their minds cannot cope with the dopamine（多巴胺）."Consequently, the overstimulation of screens and sounds lead to {#blank#}7{#/blank#} more often than not. So now parents, teachers and managers are asking how to handle the influx（汇集）of young people with this kind of addiction.

    First, monitor your cellphone use. Keep downloading applications like Forest or Checky. Then cut back on any {#blank#}8{#/blank#} usage. Set a specific goal of how much you think you should use your phone.

    Determine {#blank#}9{#/blank#} areas for cellphone use. For example, while you're at home, only allow yourself to check your phone somewhere like a home office. This way, the time in between tasks isn't {#blank#}10{#/blank#} filled with staring at your screen.

    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.

What Is a Paragraph Break?

It is one of the most important punctuation marks. A paragraph break is an indentation (缩造) or a single line space{#blank#}1{#/blank#}the division between one paragraph and the next in a body of text.

Generally, paragraph breaks serve to{#blank#}2{#/blank#}the transition from one idea to another in a stretch of text, and from one speaker to another in an exchange of dialogue.

Few readers would think of the paragraph break as a punctuation mark, but it certainly is. In ancient times there were no paragraphs. Sentences simply flowed into one another without{#blank#}3{#/blank#}.During medieval (中世纪) times, the mark evolved into the paragraph symbol and eventually became the modern-day paragraph break, which is{#blank#}4{#/blank#}now only by a line break or indentation.

Today, the paragraph break is used to give readers a break. The art of creating paragraphs is called paragraphing, the{#blank#}5{#/blank#}of dividing a text into paragraphs. Paragraphing is a kindness to your reader because it divides your thinking into manageable bites. Paragraphs that are too long{#blank#}6{#/blank#}readers with dense blocks of text to read through, while more frequent paragraphing provides readers with convenient{#blank#}7{#/blank#}points at which to take a break and relaunch themselves into thinking.

To fully understand when to insert a paragraph break, it's helpful to know that a paragraph is a group of closely related sentences that develop a central idea. Therefore, each paragraph discusses one{#blank#}8{#/blank#}topic. Also, a paragraph break is cmploycd before each new topic is introduced. In this way, the writing will flow, and readers will be able to proceed through the writing in a logical fashion instead of{#blank#}9{#/blank#}all the way to get to the last line.

Paragraphs used to be longer, but with the development of the Internet, which gives readers access to literally millions of sources of information, paragraphs have become increasingly{#blank#}10{#/blank#}. The style for many websites, for example, uses paragraphs no more than two to three sentences.
