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(邀请) but which are not real invitations. For example: "Please come over for a drink sometime." "Why not get together for a party sometime?" "Why don't you come over and see{#blank#}7{#/blank#}(we) 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 what sounds like an invitation, listen {#blank#}10{#/blank#}(careful). Is it a real invitation or not?

    Born in England in 1944, Ian Wilmut{#blank#}1{#/blank#}(know)as the leader of the research group that first cloned a female lamb {#blank#}2{#/blank#}(call)Dolly in 1996. Dolly became famous and pictures of her appeared on the{#blank#}3{#/blank#}(cover)of magazines all over the world. The{#blank#}4{#/blank#}(possible)of reproduction without a male and female being involved also made her the focus of a moral debate. For scientists, however, the cloning of dolly using the DNA of an adult cell was a breakthrough {#blank#}5{#/blank#}showed the cloning of special animals was possible.

    However,{#blank#}6{#/blank#}Wilmut thinks unlikely is human cloning. He says {#blank#}7{#/blank#}(undertake)the procedure with humans would require 29 surrogate(替代的)mothers and 300 eggs. Of those 29,28 would be bound {#blank#}8{#/blank#}(experience)failure and suffer physically and emotionally. He says he is also concerned about the psychological and{#blank#}9{#/blank#}(society)consequences a cloned might have to go through. For these reasons, he is not {#blank#}10{#/blank#}favor of it.

    Switzerland is famous{#blank#}1{#/blank#}its watches. However, this country didn't invent the watch. It was the British who did it. Here is a story of how the watch{#blank#}2{#/blank#} (bring) to Switzerland.

    Many years ago,{#blank#}3{#/blank#} Englishman traveled to Italy and on his way he stopped in a small town{#blank#}4{#/blank#}(call) Geneva in Switzerland. This Englishman traveled in a carriage(马车) inside which there was a carriage watch. This was the{#blank#}5{#/blank#}(early) kind of watch. A native shop assistant(售货员) happened to see the watch. He wondered what it was{#blank#}6{#/blank#}asked the Englishman about it. “It is a carriage watch.” answered the man. “This machine can tell the time but now {#blank#}7{#/blank#} isn't working.” At once the shop assistant offered to try repairing it. So the {#blank#}8{#/blank#} (travel) handed him the watch. The man was very clever. It was easy for him {#blank#}9{#/blank#} (repair) it. He even remembered{#blank#}10{#/blank#} it was made. And he made a watch of exactly the same type.

    To Be Joyful, To Be Young

    What really works to make sustainable changes in diet and lifestyle? It's probably not what you think. In the past 30 years of conducting clinical research, I {#blank#}1{#/blank#}(learn) that real keys are pleasure, joy and freedom. Joy of living is sustainable; fear of dying is not.

    Why? Because life is to be enjoyed. There's no point {#blank#}2{#/blank#}(abandon) something you enjoy unless you get something back that's even better, and quickly. When people eat more healthfully, {#blank#}3{#/blank#}(quit) smoking, and manage stress better, they find they feel so much better, so quickly. It reconstructs the reason for making these changes from fear of dying to joy of living.

    When you exercise and eat right, your brain receives more blood flow and oxygen, so you become smarter, have more energy, and need less sleep. Two studies showed just walking for three hours per week for only three months caused so many neurons(神经细胞) {#blank#}4{#/blank#}(grow) that it actually increased the size of people's brains!

    Your face receives more blood flow, so your skin glows more and wrinkles less. You look younger and more attractive. In contrast, an unhealthy diet, lasting emotional stress and smoking reduce blood flow to your face {#blank#}5{#/blank#}you age more quickly. Smoking speeds up aging because nicotine contributes to your blood vessel becoming narrower, {#blank#}6{#/blank#}decreases blood flow to your face and makes it wrinkle prematurely. This is why smokers look years older than they really are.

    One of the most interesting findings was that the mothers' awareness of stress was more important than {#blank#}7{#/blank#}was objectively occurring in their lives. {#blank#}8{#/blank#}(give) a questionnaire, the women were asked to rate on a three-point scale how stressed they felt each day. The women who realized they were under heavy stress had significantly shortened and damaged telomeres(染色体端粒) compared with {#blank#}9{#/blank#}who felt more relaxed. Contrarily, some of the women who felt relaxed {#blank#}10{#/blank#}raising a disabled child had more normal-appearing telomeres.

In other words, if you feel stressed, you are stressed.

    The Amber Room, an{#blank#}1{#/blank#} (amaze) treasure, which was decorated with gold and jewels, was made of several tons of{#blank#}2{#/blank#} (select) amber. It first{#blank#}3{#/blank#} (belong) to the King of Prussia and was given to Peter the Great as a gift. The Czar sent Frederick William a troop of his best soldiers{#blank#}4{#/blank#} return. Later it was moved to a palace outside St Petersburg{#blank#}5{#/blank#} Catherine Π spent her summers.

    During the Second World War, when Germany and Russia were at war, The Nazis stole the room{#blank#}6{#/blank#} (secret). In less than two days 100,000peices were put into twenty-seven{#blank#}7{#/blank#}(wood) boxes and put on a train for Künisberg. After that, what happened to the Amber Room{#blank#}8{#/blank#} (remain) a mystery and the room is now missing. Recently, the Russians and Germans have built a new Amber Room,{#blank#}9{#/blank#} looks like the old one,{#blank#}10{#/blank#} (celebrate) the 300^th birthday of the city of St Petersburg.

    When I packed up my life and moved from the comforts of my little hometown to Waco, I remember feeling {#blank#}1{#/blank#} (lose). All my friends were so excited to start their own lives, but I just wasn't sure {#blank#}2{#/blank#} I was ready for that yet. Many things worried me. But I hid my fears and when the time {#blank#}3{#/blank#} (final) came, I hugged my mother goodbye, made the two-hour one-way drive from Coppel to Waco, and set up my new room.

    For the first few weeks, I didn't miss home or really feel any kind of emotion at all except tired. There was so much for me to learn {#blank#}4{#/blank#} I hadn't had time to think about anything. My energy {#blank#}5{#/blank#} (direct) towards figuring out campus, adjusting to college-level classes and remembering the names of every new person I met. I explored every corner, {#blank#}6{#/blank#} (look) for the perfect place to study. I learned to set {#blank#}7{#/blank#} (I) a schedule of getting groceries, cleaning my room and doing my laundry on Sundays.

    Nowadays, in my second semester, I feel like I have almost adapted {#blank#}8{#/blank#} the university life. The transition from high school to college wasn't {#blank#}9{#/blank#} difficult as my mind made me think it would be. One of the best {#blank#}10{#/blank#} (thing) college has taught me is how to be independent.
