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?

    The Silk Road was a route that connected people from the East to West for hundreds of years and allowed {#blank#}1{#/blank#} (they) to trade valuable goods with each other. But there's more to the story. The Silk Road should {#blank#}2{#/blank#} (real) be called the Silk Roads. The Silk Road, {#blank#}3{#/blank#} started in China, went west and branched out into many routes.

    The Silk Road has been around for nearly 3,000 years. Most people know that valuable goods traveled along the route: silk and spices from China; jewels and wood from India; gold and animals from East Africa. These goods {#blank#}4{#/blank#} (trade) in cities along the route or ended up as far west {#blank#}5{#/blank#} Europe.

    But the people {#blank#}6{#/blank#} (travel) along the Silk Road were carrying something far {#blank#}7{#/blank#} (valuable) than their goods. They were carrying ideas and technology. European travelers returned home with stories of huge Chinese ships they had seen. The compass is an example of a(n) {#blank#}8{#/blank#} (invent) that came west from China. Europeans learned from Korean maps, which were advanced for the 1400s.

    {#blank#}9{#/blank#} was the 11, 000 km Silk Road that shaped the world we know today. The many routes were a way for different people {#blank#}10{#/blank#} (meet) each other and talk about the developing world.
