Mobile phones are becoming more and more popular not only with{#blank#}1{#/blank#}(grown-up) but also with students. Meanwhile,they also{#blank#}2{#/blank#}(become) a problem for middle schools in the past few years.Some children have got mobile phones{#blank#}3{#/blank#}Christmas or birthday gifts,and more will still want them.

    Many like SMS because it is{#blank#}4{#/blank#}(ease) and quick.Some parents felt happy because they could communicate with their children.Some teachers said mobile phone use{#blank#}5{#/blank#}(be) a distraction（分心的事）to students during school hours and{#blank#}6{#/blank#}also gave them much trouble in their classrooms.Sometimes students might use phone messages{#blank#}7{#/blank#}(cheat) during exams.A new study found that some teenagers sending messages in class even hurt their fingers because they can't stop{#blank#}8{#/blank#}(send) SMS.

    Many teachers suggested that students should not have phones at school,but if there was a good reason,they could leave their phones at school office.And even they can use the telephone in the teachers' office instead.Many people think they understand the reason{#blank#}9{#/blank#}parents would want their children to have them,but they agree schools should tell the students{#blank#}10{#/blank#}(use) their mobile phones at proper times.

{#blank#}1{#/blank#}scold by the teacher, Tom invented a story to explain why he was late.(scare)

    One night last February, a seventeen-year-old Duffy drove home along a winding road, he saw a strange light thrown against the tree. “I knew it wasn't the moon”, he said. “I drive this road all {#blank#}1{#/blank#}time and I notice little things out of place.”

    Duffy stopped his car and got out {#blank#}2{#/blank#}(examine). Below him far down in the deep valley lay a broken car with its headlights on. Thirty minutes earlier, a man had driven off the edge of the road, which has no guardrail(护栏). His car fell and rolled end over end, {#blank#}3{#/blank#}(land) on its top more than two hundred feet below.

    Duffy rushed to call for help, then returned and got down to reach the driver {#blank#}4{#/blank#}was badly injured. Snow covered the valley {#blank#}5{#/blank#}the temperature was below freezing. After struggling back up the cliff, Duffy took off his jacket and shirt and wrapped the man in time, along {#blank#}6{#/blank#} the blankets from his car.

    Life-saving {#blank#}7{#/blank#}(deed) are starting to become usual action for Duffy, the oldest of seven children. When he was 12, he saved his ten-year-old brother from drowning. Two years ago, his three-year-old sister {#blank#}8{#/blank#}(eat) rat poison, and Duffy {#blank#}9{#/blank#}(instant) cleaned out her mouth, make her drink milk to protect her stomach and called doctors.

    “We personal belief is that it is{#blank#}10{#/blank#}(meaning) for us to teach the children good values, and it looks like we have got some reward for it.” his father says.

    Johann Strauss was{#blank#}1{#/blank#}Austrian composer of light music，particularly dance music and operettas (轻歌剧). He was born in Vienna in 1825. Although his father didn't want him{#blank#}2{#/blank#}(become) a musician, Strauss studied the violin{#blank#}3{#/blank#}(secret) when he was a child. When his father discovered his son was practicing on a violin one day, he gave him a beating,{#blank#}4{#/blank#} (say) that he was going to beat the music out of the boy. But that didn't prevent the boy from becoming one of the greatest{#blank#}5{#/blank#}(composer) of all time. He wrote his first waltz at six. At the age of 19, he decided to devote himself to{#blank#}6{#/blank#}(write) music. He formed his own orchestra and made a successful tour to Europe and soon became famous. The emperor of Austria was so{#blank#}7{#/blank#}(please) with his music that he appointed him the conductor at the court balls of Vienna. It was for these occasions that he wrote some of his most popular waltzes, among{#blank#}8{#/blank#}was the well­known favorite TheBlueDanube. In all，the talented Johann Strauss wrote more than 500 masterpieces. In his lifetime, he was known{#blank#}9{#/blank#}the Waltz King, and was largely responsible for the{#blank#}10{#/blank#}(popular) of the waltz in Vienna during the 19th century.

    A few people have lucid (清醒的) dreams, in {#blank#}1{#/blank#} the dreamer is aware they're dreaming and can control the experience. Some others can learn {#blank#}2{#/blank#} (have) lucid dreams. The practice can be used to deal with frightening dreams. However, its potential has been limited by it often {#blank#}3{#/blank#} (be) so hard to achieve. Now, researchers have developed the most effective method yet for promoting lucid dreams.

    The researchers let 121 adults aged 19 to 75 pick something {#blank#}4{#/blank#} (see)in a previous dream. It was called a "dreamsign" that can serve {#blank#}5{#/blank#} a reminder to become lucid when met again. The {#blank#}6{#/blank#} (volunteer) were then handed capsules. Each person got a high-dose (大剂量的) capsule, a low-dose capsule and a placebo (无效对照剂) capsule, but they couldn't tell which was which. On three occasions, they woke in {#blank#}7{#/blank#} middle of the night, took a capsule, imagined their dreamsign and went back to sleep. The high dose was most effective, causing lucid dreams in 42 per cent of participants. About 27 per cent {#blank#}8{#/blank#} (report) lucid dreams with the low dose and 14 per cent after taking the placebo capsule.

    The potential applications are {#blank#}9{#/blank#} (excite). "This new method has the success rate we need to be able to {#blank#}10{#/blank#} (proper) do research on lucid dreaming," says Denholm Aspy at the University of Adelaide in Australia.
