We often hear people say "You've a greater chance {#blank#}1{#/blank#} (hit) by lightning." It is used to describe something {#blank#}2{#/blank#} (likely) to happen. However, {#blank#}3{#/blank#} truth is that lightning strikes are the second most common cause of deaths among natural disasters in the US. The first is floods. Around 400 Americans are struck by lightning each year, of {#blank#}4{#/blank#} about 70 people die. In fact, there are more deaths {#blank#}5{#/blank#} (cause) by lightning than by tornadoes and hurricanes. And in India, at least 2,000 people {#blank#}6{#/blank#} (kill) in lightning strikes since 2005.

    Because lightning kills only one or two people at a time, its danger does not receive as much attention {#blank#}7{#/blank#} other disasters. The US has made June 22-28 National Lightning Safety Week, aiming to deepen the public's {#blank#}8{#/blank#} (understand) of the dangers of lightning and provide safety tips during thunderstorms.

    "If you hear thunder, you are in danger of lightning," said Rocky Lopes, a disaster educator at the American Red Cross. "The most important thing is to seek a {#blank#}9{#/blank#} (hide) place. If you are near wide, open places, move indoors as {#blank#}10{#/blank#} (quick) as possible and stay there until after the storm has ended."

    {#blank#}1{#/blank#}we all know, cultural relics belong {#blank#}2{#/blank#}the people all over the world. Nowadays, more and more people are interested in the topic about {#blank#}3{#/blank#} to protect cultural relics such as places of interest, old city{#blank#}4{#/blank#} (wall), folk arts and so on. Some even advise {#blank#}5{#/blank#}(devote) to new culture exhibitions in order to educate the public. As {#blank#}6{#/blank#} matter of fact, the Chinese government has been {#blank#}7{#/blank#} (concern) about the topic and {#blank#}8{#/blank#}(take) measures. At the same time, more and more foreigners are coining to enjoy Chinese culture{#blank#}9{#/blank#} we are sure the interest in Chinese relics abroad will be {#blank#}10{#/blank#}(great).

    When Joe was about to start school, all signs pointed to success. Yet things turned out  {#blank#}1{#/blank#}(be) quite disappointing. The fourth grade even found him at the bottom of the class. Joe struggled day and night, but  {#blank#}2{#/blank#}made him upset was that it did not work—until one stormy afternoon.

    On that afternoon, the math teacher was introducing difficult concepts  {#blank#}3{#/blank#}dark clouds covered the sky, and the storm set in. Although she tried to make the kids concentrate, the thunder won the battle for their attention. No one grasped the concepts. Except for Joe. He understood{#blank#}4{#/blank#} and answered all the questions correctly. The teacher patted him on the back and told him to go around to the others and explain how he had managed it. {#blank#}5{#/blank#}(encourage) by his newfound success, Joe moved quickly throughout the room. Soon math time  {#blank#}6{#/blank#}(follow) by the time for art. All children  {#blank#}7{#/blank#}(natural) drew dark pictures on such a day. Except for Joe.

    Since then, Joe started to work even  {#blank#}8{#/blank#}(hard) than before. His math teacher was always curious about the  {#blank#}9{#/blank#}(amaze) change: Why had that stormy day changed Joe?

    At the graduation ceremony, Joe presented the teacher with his most familiar  {#blank#}10{#/blank#}(possess) — the picture of bright yellow sun. On the picture Joe had written: This is the day I woke up to my brightness.

    One of the biggest challenges {#blank#}1{#/blank#} (face) students today is how to concentrate on studies. Almost all of them are struggling for their concentration power. In an age {#blank#}2{#/blank#} mobile phones and Internet are eating up most of our time and energy, one can understand how different it is to focus attention and energy on studies.

    One of the most important {#blank#}3{#/blank#} (factor) for developing concentration on a task, whether it is study or anything else, {#blank#}4{#/blank#} (be) to develop an interest in that task. We are able to focus {#blank#}5{#/blank#} (easy) and more long periods of time on tasks that we find more interesting. If you ever want to concentrate on anything and studies are no {#blank#}6{#/blank#} (except), you need {#blank#}7{#/blank#}(ensure) that the environmental around you is distraction (注意力分散) free. So the question is not how to concentrate on studies {#blank#}8{#/blank#} how to avoid distractions that have swallowed up mankind today. The only way to guarantee {#blank#}9{#/blank#} distraction free environment is by getting rid of all the unnecessary things around you, including the electronic gadgets (小器具) {#blank#}10{#/blank#} mobile phones.
