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?

    Since the beginning of the 21^st century, artificial intelligence (AI) {#blank#}1{#/blank#} (find) its way in different areas in the entertainment industry. Disney, which is one of the world's leading entertainment {#blank#}2{#/blank#} (company), has decided to make use {#blank#}3{#/blank#} the technology in its theme parks, where robot cartoon characters will soon walk among guests. Disney has also its robot Mickey Mouse and Donald Duck to communicate with tourists.

    “I think AI is going to be {#blank#}4{#/blank#} (great) important for what we do," said Jon Snoddy, an official of the entertainment company. "Robot characters that can move around among our guests need to understand where they're going and know {#blank#}5{#/blank#} to behave in a world with humans.”

    However, the company also {#blank#}6{#/blank#} (know)some of the fears surrounding AI. {#blank#}7{#/blank#} (scare) kids won't be part of what we do, said Mr Snoddy. "We will go and do tests in our parks to find out what kids find {#blank#}8{#/blank#} (interest) about these things. We will carry out tests {#blank#}9{#/blank#} (make) sure the robot characters make a positive {#blank#}10{#/blank#} (impress) on kids.”

    For Nigel Portman, a love of travelling began with what's called a "gap year". In common with many other British teenagers, he chose {#blank#}1{#/blank#} (take) a year out before settling down to study for his degree. After doing various {#blank#}2{#/blank#} (job) to raise some money, he left home to gain some experience of life in different cultures, visiting America and Asia. The more adventurous a young person, the {#blank#}3{#/blank#} (great) challenge they are likely to set {#blank#}4{#/blank#} (them) for the gap year, and for some, like Nigel, it can result in a thirst for adventure.

    Now that his university course {#blank#}5{#/blank#} (come) to an end, Nigel is just about to leave on a three—year trip that will take him right around the world. What's more, he plans to make the whole journey {#blank#}6{#/blank#} (use) only means of transport which are powered by natural energy. In other words, he'll be relying {#blank#}7{#/blank#} (main) on bicycles and his own legs; and when there's an ocean to cross, he won't be taking a shortcut (捷径) {#blank#}8{#/blank#} flying aboard—he'll be joining the crew of a sailing ship, instead.

    As well as doing some mountain climbing along {#blank#}9{#/blank#} way, Nigel hopes to pass on to the people he meets the environmental message {#blank#}10{#/blank#} lies behind the whole idea.

    When I was a kid, Mom used to cook food for us. One night after {#blank#}1{#/blank#} (spend) a long hard day at work, Mom placed a plate of bread jam and {#blank#}2{#/blank#} (extreme) burnt toast（烤面包） in front of my dad, I was waiting {#blank#}3{#/blank#} (see) if he noticed it. However, while eating his toast. Dad just asked me {#blank#}4{#/blank#} my day was at school. I don't remember what I told him that night,{#blank#}5{#/blank#} I do remember I heard Mom apologizing to Dad for burning the toast. I'll never forget what Dad said, "Honey, I love burnt toast."

    Later that night, I {#blank#}6{#/blank#} (go) to kiss Daddy good night and asked him if he really liked his toast burned. He gave me {#blank#}7{#/blank#} big hug and said, "Your mamma put in a long hard day at work today, really {#blank#}8{#/blank#} (tire). Besides, a burnt toast never hurts but cold words do!"

    What I've learned over the years {#blank#}9{#/blank#} (be) that learning to accept each other's faults is one of the most important {#blank#}10{#/blank#} (key) to creating a healthy, growing and lasting relationship.

It is widely accepted that optimistic attitudes promote health as well as happiness. The secret of a long life is {#blank#}1{#/blank#} (universe) desired and has long been sought. Today we can reveal it: always look on the bright side. A huge research project {#blank#}2{#/blank#} (lead) by scientists at the Boston University School of Medicine concludes that optimists live {#blank#}3{#/blank#} (long).

Lewina Lee, lead author of the study, said, "A lot of evidence {#blank#}4{#/blank#} (suggest) that exceptional longevity(长寿) is widely accompanied by a longer span of good health and living {#blank#}5{#/blank#} disability. Therefore our findings raise an exciting possibility {#blank#}6{#/blank#} we may be able to promote health and happiness by {#blank#}7{#/blank#} (develop) positive attitudes such as optimism."

However, the study doesn't suggest that we should aim for great pleasure. Sadness is {#blank#}8{#/blank#} important part of the human condition. Any normal person sometimes experience disappointment, ambitions and the {#blank#}9{#/blank#} (lose) of loved ones. But for many people, these matters of human existence {#blank#}10{#/blank#} (transform) into an abnormal state of despair. There is a vital place in public health for providing mental treatment in helping to correct these cognitive errors. It is not weakness to be defeated by setbacks. It is merely a mistake.
