Texting while walking is something that most of us are guilty of．We can't help {#blank#}1{#/blank#}(reply)to that message we just received．However，while it's fun to keep up to what's going on，we may actually put{#blank#}2{#/blank#}(we)in danger．

    A team of researchers from UK recently found people{#blank#}3{#/blank#}use their phones while on the move walk differently．During the research，a group of 21 volunteers{#blank#}4{#/blank#}(ask)to walk around a street with obstacles(障碍物)such as a step.{#blank#}5{#/blank#}volunteers traveled the course a total of 12 times each，either writing or reading a message，making a call，or with no phone at all．It took the volunteers 118 percent {#blank#}6{#/blank#}(long)to complete the course while using a phone．They also paid attention to the travel path 51 percent more when they weren't using a phone．“Although there{#blank#}7{#/blank#}(be)no accidents，we should still be aware{#blank#}8{#/blank#}what's going on around us，”according to Matthew Timmis，co—author of the study．The big risk is suddenly—appearing situations，like someone suddenly walking in front of you．You are not going to be able to respond to that{#blank#}9{#/blank#}(swift)enough，so you may injure yourself or get injured．In a word，these hidden{#blank#}10{#/blank#} (danger)of texting while walking should be recognized to avoid injuries．

    Recently, with the increasing popularity of social websites and personal online blogs, the potentially harmful practice of oversharing {#blank#}1{#/blank#} (become) much more common. Oversharing is the act of sharing too much information, or TMI,{#blank#}2{#/blank#} people who are not necessarily prepared or qualified to receive it. Telling a co-worker you don't want a piece of birthday cake may be acceptable, {#blank#}3{#/blank#} adding the fact that you're on a diet to lose 50 pounds would be oversharing. There are some {#blank#}4{#/blank#} (person) facts others may not need or want to know.

    Some oversharing is the result of a poorly {#blank#}5{#/blank#} (develop) social filter (过滤器) or “shut up button”. Different people may have different ideas over {#blank#}6{#/blank#}constitutes (构成) oversharing or TMI, so they may not realize they are making others feel {#blank#}7{#/blank#} (comfortable).

    Other times the oversharing may be an attempt {#blank#}8{#/blank#} (break) the ice socially. By sharing a few embarrassing {#blank#}9{#/blank#} (moment) with strangers, the oversharer lets others know it's okay to let down their guards and be more open themselves.

    While some oversharing may be OK,{#blank#}10{#/blank#} is generally a good idea to develop a sense of propriety (得体) in order to avoid sharing far too much information.

    Joris Hutchison, 10 years old, of Seattle, has worked hard all year to save cheetahs（猎豹）from the very real threat of extinction. He has raised more than $14,000 to purchase GPS devices, {#blank#}1{#/blank#} follow and protect the animals. He earns money by selling lemonade, flowers and T-shirts, and by {#blank#}2{#/blank#}(organize) skating parties and a garage sale. What moved the public {#blank#}3{#/blank#}(be) that Joris donated all that he raised to a wildlife conservation organization and shelter in Namibia where he and his mother have volunteered for {#blank#}4{#/blank#} past three summers.

    As the group's {#blank#}5{#/blank#}(young) of all the volunteers, Joris prepares food, cleans enclosures（围场）, and creates improvement {#blank#}6{#/blank#}(item) for the cheetahs that live there, all of whom {#blank#}7{#/blank#}(injure) or raised by human beings in the past. The shelter protects cheetahs in the wild by convincing farmers not {#blank#}8{#/blank#}(shoot) the animals and instead, to allow the ones accused {#blank#}9{#/blank#} killing farm animals to be fixed with GPS devices. “I've learned that everyone can make a {#blank#}10{#/blank#}(different), even if you're just a kid!” Joris told Gloria Barron Prize for Young Heroes. “You just have to start somewhere.”

    Last Saturday, my friend and I were walking back home after a nice evening. I {#blank#}1{#/blank#}(ask) my friend if we could walk through the town instead of taking our usual shortcut. So we did. {#blank#}2{#/blank#} (sudden), a few {#blank#}3{#/blank#}(step) ahead, we saw a woman, {#blank#}4{#/blank#}was sitting on the edge of the sidewalk. She looked bad and when we asked her if she felt all right, we realized she was badly injured{#blank#}5{#/blank#} covered with blood. While my friend can back to our closest friend's place to get a thick cover, a young fellow joined {#blank#}6{#/blank#} (we) and called an ambulance. All along I sat next {#blank#}7{#/blank#} her, talking and {#blank#}8{#/blank#} (listen) to keep her awake until the ambulance arrived. She was badly {#blank#}9{#/blank#}(shock) and started to fall asleep. I knew that it was of great {#blank#}10{#/blank#}(dangerous) and she might have lost consciousness（意识）. We hope she is safe and sound now.

    One news story about the modem Olympics is about men {#blank#}1{#/blank#} (pretend) to be women to enter the women's events, People are arguing about how fair {#blank#}2{#/blank#} is to test woman athletes to make sure they are not men. One side argues that men are {#blank#}3{#/blank#} (strong), so they will win any women's event. They say that women should be tested to make sure they are not men. The other side argues that this is {#blank#}4{#/blank#} (fair)to women. They say skill is more important than strength. But has this ever really happened? {#blank#}5{#/blank#} answer is yes, several times! The most famous case is that of Dora in the 1936 Olympic Games.

    The Olympics {#blank#}6{#/blank#} (hold) in Berlin, Germany, three years after the Nazis came {#blank#}7{#/blank#} power. The Nazis wanted to win lots of events, but they had wrong ideas about race. They did not want black or Jewish people in the German team. But many of their best athletes were Jewish. The Nazis did not let these athletes compete. But that meant they might lose events! One event {#blank#}8{#/blank#} the Nazis thought they might lose was the women's high Jump. So the Nazis sent a male athlete, Hermann Ratjen, {#blank#}9{#/blank#} (compete) under the name of “Dora”. Did he win? No. “Dora” came fourth. The {#blank#}10{#/blank#} (win) was a young Jewish woman from Hungary. She jumped 1.60 metres. “Dora” only jumped 1.58 metres. So men do not always win.

The college entrance examination is just around the corner. {#blank#}1{#/blank#} (assign) and tests will keep many of you up late at night, and you may plan to make up for your{#blank#}2{#/blank#} (lose) sleep during the weekends. But is it useful?

A study shows that the habit of sleeping in{#blank#}3{#/blank#} weekends doesn't fix the damage done by a lack of sleep during the week. Even {#blank#}4{#/blank#} (bad), it may damage your health.

In the study, {#blank#}5{#/blank#} was conducted over 10 days, 36 healthy young men and women with different sleep requirements {#blank#}6{#/blank#} (divide) into three groups. The researchers found that people who lacked sleep ate more snacks and gained {#blank#}7{#/blank#} (weigh) quickly. That could be partially due to the shifting of the{#blank#}8{#/blank#} (biology) clock and changes to certain body hormones especially hunger hormones.

And {#blank#}9{#/blank#} they tried to sleep for as long as they wanted to on weekend, it was still insufficient(不够的) to meet standard sleep time because they found it difficult to fall asleep. Moreover, they were more likely{#blank#}10{#/blank#}(show) increased sensitivity (敏感性) to insulin(胰岛素) in both their muscles and their livers.
