The Han people have its own spoken and written language-Chinese. Chinese belongs to the Han-Tibetan language family. It is the {#blank#}1{#/blank#} (common) used language in China and among the largest languages in the world.

    Written Chinese came out in {#blank#}2{#/blank#} (it) earliest form approximately 6,000 years ago. The Chinese characters {#blank#}3{#/blank#} (use) today, also called “Hanzi”, developed from those used in bones and tortoise shells more than 3,000 years ago. There are about 56,000 characters, of which only about 3,000 are in common use.

    Mandarin is a category (种类) of Chinese {#blank#}4{#/blank#} (dialect) spoken across most of northern and {#blank#}5{#/blank#} (southwest) China. The term “Mandarin” can also refer to Standard Mandarin, which {#blank#}6{#/blank#} (base) on the Mandarin dialect spoken in Beijing. It is officially considered to be the standard for the People's Republic of China.

    Why do most non-Chinese speakers choose to learn standard Mandarin Chinese? Mandarin is understood by most Chinese people. As mentioned above, it is China's national language. {#blank#}7{#/blank#} you are interested in basic communication, scholarly research, or {#blank#}8{#/blank#} (pursue) a career in China, standard Mandarin is {#blank#}9{#/blank#} necessary tool for communication. And it often serves {#blank#}10{#/blank#} a bridge for communication.

    In Canada and the United States, people enjoy entertaining(请客) at home. They often invite friends over{#blank#}1{#/blank#}a meal, a party, or just for coffee and conversation.

    Here are the {#blank#}2{#/blank#} (kind) of things people say when they invite someone to their home:

    "Would you like to come over for dinner Saturday night?" "Hey, we {#blank#}3{#/blank#}(have) a party on Friday. Can you come?" {#blank#}4{#/blank#}(reply) to an invitation, either say thank you and accept, or say you're sorry and give an excuse: "Thanks, I'd love to. What time would you like me to come?" {#blank#}5{#/blank#} "Oh, sorry. I've tickets for a movie."

    Sometimes, {#blank#}6{#/blank#}, people use expressions that sound like invitations but which are not real invitations. For example: "Please come over for a drink sometime." "Why not get together for {#blank#}7{#/blank#} party sometime?" "Why don't you come over and see us sometime soon?"

    They are really just polite ways of {#blank#}8{#/blank#} (end) a conversation. They are not real invitations because they don't mention a specific(确定的) time or date. They just show that the person is trying to be {#blank#}9{#/blank#} (friend). To reply to expressions like these, people just say "Sure, that would be great!" or "OK. Yes, thanks."

    So next time when you hear {#blank#}10{#/blank#} sounds like an invitation, listen carefully. Is it a real invitation or is the person just being friendly?

    So why has English changed {#blank#}1{#/blank#} time? Actually all languages change and develop {#blank#}2{#/blank#} cultures meet and communicate with each other. At first the English spoken in England between about AD 450 and 1150 was very different from the English spoken today. It was based more on German {#blank#}3{#/blank#} the English we speak at present. Then gradually between about 800 and 1150, English became {#blank#}4{#/blank#} (little) like German because those {#blank#}5{#/blank#} ruled English spoke first Danish and later French. These new comers {#blank#}6{#/blank#} (rich) the English language and especially {#blank#}7{#/blank#} (it) vocabulary. So by the 1600s Shakespeare was able to make use of a wider vocabulary than ever before. In 1620 some British {#blank#}8{#/blank#} (settle) moved to America. Later in the 18^th century some British people {#blank#}9{#/blank#} (take) to Australia too. English began to be spoken in both countries. Today, {#blank#}10{#/blank#} number of people learning English in the world is increasing rapidly.
