—No. On the contrary, I think it is very necessary.

    What can keep your brain young and active? Marie Pasinski{#blank#}1{#/blank#} doctor from Massachusetts General Hospital, says, “New experiences as well as a good snack.”

    The next time you feel{#blank#}2{#/blank#} (bore) at the pool, play a board game or cards. Exercising your mind with a challenging game that requires brainpower,{#blank#}3{#/blank#} chess or bridge (桥牌), is more than just fun. These types of games are so interesting{#blank#}4{#/blank#} they can build up working memory. Traveling, especially in the places where English isn't spoken, can make you{#blank#}5{#/blank#} (smart) and more intelligent. There is a great deal of recent research proving its benefits.

    {#blank#}6{#/blank#} the other hand, eat more nuts! Not only are nuts the perfect snack for a summer road trip, they also keep your mind sharp. Some nuts are rich in magnesium(镁),{#blank#}7{#/blank#}can improve learning skills and memory of mice. The research{#blank#}8{#/blank#} (publish) in the Journal Neuron last month. Another study at New York State Institute also proved the point{#blank#}9{#/blank#} (show) that mice who ate nuts made improvements in learning, memory, emotional regulation and movements, compared with{#blank#}10{#/blank#} who didn't eat nuts.

    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.

    Just now, I entered the website "Topic for Today". I feel{#blank#}1{#/blank#}(interest) in the report on middle school students' using cell-phones on campus. In fact，more students now come to school{#blank#}2{#/blank#} cell-phones. My schoolmates have different opinions. Some think{#blank#}3{#/blank#}is convenient to get in touch with others with the cell-phone,{#blank#}4{#/blank#}also makes them feel safe especially in time of trouble. Besides，it is nice to enjoy{#blank#}5{#/blank#}(variety) functions of different cell-phones.

    Others think differently. First，the cell-phone is not{#blank#}6{#/blank#}must in school，as there are some IC phones there,{#blank#}7{#/blank#}(make) it easy to call others. Second, many students often play e-games and send{#blank#}8{#/blank#}(message) with their cell-phones, even in class, which will surely have bad effects on their study. What's more, a large amount of time and money will{#blank#}9{#/blank#}(waste).In my opinion, the cell-phone is a useful tool in our daily life. But it doesn't mean we can use it {#blank#}10{#/blank#}(free) in school.

    A few months after returning the US from Germany, I took part in a college course in French. Since I had learned to speak German good in Germany, I thought that it might be interested to begin studying another language.

    On September 11, 2001, Omar Eduardo Rivera, a blind computer technician (技术员), was working on the 71st floor of the World Trade Center with his guide dog {#blank#}1{#/blank#} (name) Dorado. When the hijacked (被劫持的) plane hit the tower, Rivera knew {#blank#}2{#/blank#} would take him a long time to escape from the building, but he wanted his lovely dog to have a chance {#blank#}3{#/blank#} (get) out so he set him free in the crowded stairwell. "I thought I was lost forever—the noise and the heat were {#blank#}4{#/blank#} (terrify) —but I had to give him the chance of escape. So I touched his head, gave him a push and ordered him to go," Rivera said.

    The dog {#blank#}5{#/blank#} (immediate) disappeared into the crowd, but a few {#blank#}6{#/blank#} (minute) later Rivera felt the dog feeling his legs. Dorado came right back to his side and a co-worker {#blank#}7{#/blank#} (bring) by him as well. Then Dorado and the selfless co-worker {#blank#}8{#/blank#} (help) Rivera climb down 70 flights of stairs, {#blank#}9{#/blank#} took nearly an hour. No sooner had they escaped from the building {#blank#}10{#/blank#} it fell down completely, and Rivera says he owes his life to his faithful dog.

    The powerful Hurricane Barry weakened but remained a weather nightmare on Tuesday. It {#blank#}1{#/blank#} (strike) parts of Arkansas with at least six{#blank#}2{#/blank#} (inch) of rain and caused flash flooding that drowned {#blank#}3{#/blank#}animal shelter and killed a puppy.

    Heavy rains were falling. The Humane Society of Clark County issued an SOS after flooding drowned its recently rebuilt shelter. "SOS! We are flooded. It's on the building! "the official said in a Facebook post. "We need help! Can any of you keep a dog {#blank#}4{#/blank#}two at your houses? Help! Help! Help!" Video from the scene showed wet dogs wandering loose in the shelter, the floor covered in water. Many offered their homes and yards {#blank#}5{#/blank#}the animals. A short time {#blank#}6{#/blank#}(late), the official posted an update on Facebook{#blank#}7{#/blank#}(say) foster homes have been found for all 72 dogs. "We are so blessed! People from all over have come to {#blank#}8{#/blank#} (we) rescue. Donations. Cleaning. Fostering. It's really{#blank#}9{#/blank#} (impress)." the post said. After the rainfall, a ray of sunshine shone brightly in the states {#blank#}10{#/blank#}the storm burst last week.
