You are twenty-one years old and live a happy and peaceful life. {#blank#}1{#/blank#} one day, your doctor tells you that you have a serious disease and will die soon. What would you do?{#blank#}2{#/blank#} (probable) most of us might feel very sad and give up our dreams and hopes for the future. Here is {#blank#}3{#/blank#} the great scientist, Stephen Hawking, did.

    Hawking wasn't {#blank#}4{#/blank#} (discourage) because of his physical condition.{#blank#}5{#/blank#}, he went on with his study of the universe. In 2002, Hawking was invited to China. He told Chinese students about his theories and thoughts {#blank#}6{#/blank#} some of the greatest questions: what is time, how the universe began, and what are black holes. He impressed the audience with his humor, confidence and of course his {#blank#}7{#/blank#} (wise).

    Hawking became famous in the early 1970s. In 1988, he wrote A Brief History of Time, in {#blank#}8{#/blank#} he explained difficult theories in a simple way. The book {#blank#}9{#/blank#} (sell) well since it came out.

    Stephen Hawking is a man with a strong will and he is regarded as the {#blank#}10{#/blank#} (great) mind in physics since Albert Einstein.

    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?
