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 since2005.

    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.”

    Zoos are places {#blank#}1{#/blank#} animals are kept. There are some reasons {#blank#}2{#/blank#} keeping animals in zoos.

    Firstly, zoos are entertaining and interesting places of children. Most children like to see animals in zoos. Zoos also offer people {#blank#}3{#/blank#} (live) in big cities a chance of getting close to nature.

    Secondly, it is easier for scientists to research animals' lives when they are kept in zoos than they are in forests. Scientists can study animals' {#blank#}4{#/blank#} (relate), their life cycles, or their habits to learn how to breed animals, {#blank#}5{#/blank#} can reduce animal {#blank#}6{#/blank#} (extinct).

    Furthermore, the risk of dying out of some {#blank#}7{#/blank#} (endanger) animals is reduced because they are kept in safety.

    {#blank#}8{#/blank#}, zoos also cause some problems for animals, such as restrictions on their freedom. They also lose their “wild” character. For example, tigers might lose their {#blank#}9{#/blank#} (hunt) skills. Besides, zoos cost a lot of money for land, animals' food and labors. This may charge {#blank#}10{#/blank#} (expense) for people who want to visit zoos.

    Crossword puzzles and exercise are just a few of the habits that improve memory best. But to {#blank#}1{#/blank#}(true) give your brain a push, you might want to take a simple tip to heart-and it's nothing you learned in school.

    So far, researchers from Waterloo University in Canada {#blank#}2{#/blank#}(discover) what may be the easiest way to improve your memory ever. Their research, recently {#blank#}3{#/blank#}( publish) in the journal Memory, suggests that reading out loud to yourself can increase your recall skills {#blank#}4{#/blank#}up to 15%.

    In the study, scientists asked 95 participants to test four {#blank#}5{#/blank#}(method): reading, silently, hearing someone else read, reading aloud and listening to a recording of oneself reading. Their result? The people{#blank#}6{#/blank#}read the information out loud showed the best retention(保持)rates—about 15%{#blank#}7{#/blank#}(high) in learning speed, in fact. You may want to add these brain-boosting foods that can improve memory to your diet, too.

    “Read{#blank#}8{#/blank#} needs to be remember out loud, and you'll remember it better. Yes, it's shat simple!” psychologist and study co-author Colin Macleod said.

    So next time when you're preparing for a big exam, spend some time{#blank#}9{#/blank#} (read) loud. Trust us. It might make you{#blank#}10{#/blank#}genius.

    Fu Xuewei, a 25-year-old girl from Chengdu, China {#blank#}1{#/blank#}（recent）shared a beautiful set of wedding photos on the Internet. However, there's a debate on the photographs {#blank#}2{#/blank#} no groom（新郎）seems to be found in the photos. In fact, the only people {#blank#}3{#/blank#}（feature）in the photos are Ms. Fu and her 87-year-old grandfather.

    Despite having no plans of getting married anytime soon, Fu decided {#blank#}4{#/blank#}（wear）the wedding dress for her grandfather. The man fell seriously ill last September, with doctors warning that he could pass away{#blank#}5{#/blank#} any time. Fearing he might never get to fulfill the dream of walking her down to the Mr. Right, Fu arranged the surprise photoshoot. Keeping her plans a secret, she took {#blank#}6{#/blank#}（she）grandfather for a regular hospital check-up, only to reveal that they were going to take pictures later and he agreed.

    Ms. Fu {#blank#}7{#/blank#}（raise）by her grandparents from the age of ten,{#blank#}8{#/blank#} makes them mean a lot to her. She insists on taking care of them in return. The young woman even {#blank#}9{#/blank#}（have）a tattoo（纹身）of her grandfather. “I had my grandfather's appearance tattooed on my arm because I want all my new {#blank#}10{#/blank#}（friend）to know what he looks like in the future,” she said.
