A man looking at his smartphone while walking across a railway crossing in Nanjing {#blank#}1{#/blank#} (have) a close knock on Oct 22. He was so {#blank#}2{#/blank#} (absorb) in his smartphone that he didn't see a train approaching until it brushed past him, {#blank#}3{#/blank#} (throw) him to the ground. This should serve {#blank#}4{#/blank#} a warning that people should be aware of their surroundings, especially {#blank#}5{#/blank#} crossing roads.

    {#blank#}6{#/blank#} (lucky), the man survived, but the incident forced the driver {#blank#}7{#/blank#} (stop) the train. An l8-minute delay followed the incident, {#blank#}8{#/blank#} led to a break in the running of other trains on the route.

    The Smartphone {#blank#}9{#/blank#} (addict) has spread like an infectious（传染的）disease. It's evident that it will do great harm to society. What's even {#blank#}10{#/blank#} (bad), some addicts become impatient with relatives and friends.

    Some people blame the smartphone for the sad story, yet in fact people's weakening self-control and self-discipline are to blame.

    The sun at the center of our Solar System is one of the big reasons for{#blank#}1{#/blank#}we're here today, but it can also be a big trouble from time to time. Coronal mass ejections(CMEs) (日冕物质喷发)can seriously damage human{#blank#}2{#/blank#}(communicate) systems.

    For years, researchers{#blank#}3{#/blank#}(attempt) to forecast and predict CMEs in {#blank#}4{#/blank#}hope that warnings could help prevent damage to electronics and the power grid (电网). As it turns{#blank#}5{#/blank#}that a CME is more like a sneeze. Professor Mathew Owens of the University of Reading explains, "The research team and I have found they are more like an{#blank#}6{#/blank#}(expand) dust cloud or sneeze."

    When the solar wind acts on the CME as it moves through space, it causes the shape and behavior of the energy explosion {#blank#}7{#/blank#}(become) unpredictable. "Therefore if we want to protect{#blank#}8{#/blank#} (we) from solar eruptions, we need to understand more about the solar wind, "Owens says.

    The research team suggests that solar wind readings should {#blank#}9{#/blank#} (include) in the forecasting and prediction of future CMEs. This study could help scientists more{#blank#}10{#/blank#}(accurate) assess the risk that the ejections bring to human technology and potentially help reduce the damage they cause.

    The first UN Chinese Language Day at the United Nations {#blank#}1{#/blank#}(observe) on Friday at UN Headquarters in New York in 2010. {#blank#}2{#/blank#}the world's most widely spoken language, it seems appropriate that Mandarin(普通话) has one day every year dedicated(把……专用于) to it. This{#blank#}3{#/blank#}(official)marked day of Mandarin language celebration was set by the United Nations as a way of {#blank#}4{#/blank#}(celebrate) the language's history and contributions to the world.{#blank#}5{#/blank#} is hoped that having one day every year to celebrate Mandarin will encourage more people around the world to take it up. With China likely to become the {#blank#}6{#/blank#}(large) economy in the world, it is important that the wider world becomes interestingly more perfect in this wonderful language. Every year UN Chinese Language Day {#blank#}7{#/blank#}(fall) on April 20. A great way {#blank#}8{#/blank#}(get) involved in the celebration is to join a Mandarin class or attend one of the Confucius Institutes(孔子学院){#blank#}9{#/blank#}are set up by China in countries around the world. The number of people learning Chinese is on {#blank#}10{#/blank#}increase in China's neighboring countries, such as Korea, Japan, and Vietnam.

    One day, there was a blind man sitting at the roadside. There was a sign beside him, on{#blank#}1{#/blank#}was written, “I'm blind. Please help me." Many people walked by him,{#blank#}2{#/blank#}few of them helped him.

    A young man was going to his office. While{#blank#}3{#/blank#}(walk) by the blind man, he stopped and found that there were few coins in the man's hat. He bent down and write a new message on the sign without asking for{#blank#}4{#/blank#}(permit), and then he left, without saying a word.

    {#blank#}5{#/blank#}(late) that afternoon, when the young man walked by the blind man again, he saw the hat{#blank#}6{#/blank#}(fill) with bills and coins. The blind man recognized his footsteps and asked if{#blank#}7{#/blank#}was he that had changed his sign. He also wanted to know {#blank#}8{#/blank#}the young man had done to the sign. Then the young man told the blind man that he {#blank#}9{#/blank#}(write) something like this on the sign. “It is spring now, but I can't see it." The blind man expressed his gratitude to the young man and went home{#blank#}10{#/blank#}(happy).
