"You'll think twice about plucking your eyebrows (拔眉毛) {#blank#}1{#/blank#} you find their important role," says Greg Foot. They are one of {#blank#}2{#/blank#} most expressive(有表现力的) parts of our bodies. {#blank#}3{#/blank#} your eyebrows, you can tell your feelings to other people. {#blank#}4{#/blank#} is that their only purpose (目的)?

    Over several thousand {#blank#}5{#/blank#} (year), we have lost lots of body hair, so it's strange that hair still {#blank#}6{#/blank#} (remain) on our brows. Some scientists say that eyebrows mainly work as {#blank#}7{#/blank#} special form of protection for the eyes. In fact, their job is so {#blank#}8{#/blank#} (importance) that some researchers are sure that if we didn't have {#blank#}9{#/blank#} (they), we'd have evolved (进化) some other facial features to {#blank#}10{#/blank#} (do) the same task.

    Let me tell you something about Mr Lu. He lives n{#blank#}1{#/blank#} to us. He is a Maths teacher. He is about forty years old and looks very strict (严格的) . In fact, after class he is very k{#blank#}2{#/blank#}.

    He always gets up very e{#blank#}3{#/blank#} and he always goes to w{#blank#}4{#/blank#} very early too. In class, he is very strict. If a student makes a noise, he will be very a{#blank#}5{#/blank#}. He always tells his students ,“We're h{#blank#}6{#/blank#}a Maths class now,aren't we? Don't make any noise, OK?”

    But when class is o{#blank#}7{#/blank#},Mr Lu is very kind and f{#blank#}8{#/blank#} He always tells jokes to his students. His students are always very h{#blank#}9{#/blank#} because the jokes are very i{#blank#}10{#/blank#}.

    It was a long day. David felt {#blank#}1{#/blank#} (happy) as he walked home slowly. He couldn't help thinking about his stupid mistake on the school soccer field. He missed scoring that goal. It made the school team {#blank#}2{#/blank#} (lose) in the game.

    As soon as he arrived home, his mother found his sadness, for it {#blank#}3{#/blank#} (show) on his face. After {#blank#}4{#/blank#} (hear) the whole story, she told {#blank#}5{#/blank#} (he) that it was not necessary to be too hard on himself and winning or losing was only half the game. She asked David {#blank#}6{#/blank#} (communicate) with his teammates. She added that the most important thing was to support each other in a team. What his mother said made him think a lot.

    The next day, David went to soccer practice {#blank#}7{#/blank#} courage instead of fear in his heart. He apologized to his teammates for his mistake. He said they should continue to work together as {#blank#}8{#/blank#} whole team. It was a relief that his {#blank#}9{#/blank#} (teammate) all agreed with him. They promised to encourage each other and work much {#blank#}10{#/blank#} (hard) the next time.

    Pets are wonderful friends and they can always be around. They provide their owners {#blank#}1{#/blank#} love and comfort. Some animals do even more {#blank#}2{#/blank#} that. Service animals can help disabled (残疾的) people. Over 12,000 disabled people use service animals to{#blank#}3{#/blank#} them to live an easier life.

    Service animals are not pets. They have an important {#blank#}4{#/blank#} to do. We know pets can't get into business and public places, {#blank#}5{#/blank#} service animals can. They can visit restaurants, hotels and hospitals.

    The most well-known service animals are {#blank#}6{#/blank#} . They are Seeing Eye Dogs. A person, if there is something wrong with his eyes, needs this kind of dogs. These dogs must {#blank#}7{#/blank#} clever and kind. There are other kinds of service animals, too. If there is something wrong with his {#blank#}8{#/blank#} , he could keep a hearing cat to make him know noises around him. Service monkeys can get something for their owners, if their owners can't move.

    Animals {#blank#}9{#/blank#} our lives wonderful in many ways. Some animals help disabled people live an independent(独立的)life. Others give their owners comfort in a sad moment, or protect the owner when they are in danger. No matter what they do, animals are special friends. We should regard them {#blank#}10{#/blank#} a real friend.
