    A so-called “smart drug” intended to improve people's cognitive (认知的) function to protect the brain from altitude sickness.

    Visiting high-altitude sites for work, spot, religious pilgrimages and military can result in cognitive effects, including memory loss and attention difficulties. There's little you can do to prevent these symptoms except acclimatize -but this takes time and doesn't always work. A drug called oxiracetam might be the answer.

    ShengLi Hu at the Third Military Medical University, Chongqing, China and her colleagues studied the performance of male military personnel at altitude. All lived in towns around 1,800 meters above sea level, During the study, they spent eight days at this altitude and then climbed for three days to reach 4,000 meters, where they stayed for up to a month.

    Twenty participants took oxriacetam three times a day for the first 15 days of the study, while another 20 received no intervention. The man did tests of attention and memory at the start and end of the study and 20 days in, by which time they had been at 4,000 meters for nine days.

    While all the participants experienced a drop in cognitive ability at 4,00 meters, those who took oxiracetam showed a much smaller drop than the control group.

    The team found that at high altitude the brain stem, which plays a critical role in supporting basic living functions, received blood at the expense of areas responsible for more advanced cognitive functions. But in people who took oxiracetam, blood flowing throughout the brain rose, thus offering more oxygen to these areas. This may be how the drug seems to lessen cognitive problems like with low oxygen.

    It isn't yet known whether diverting blood in this way could have negative effects in the long run. "The results are striking and imply that oxiracetam may be beneficial for helping to relieve cognitive ability decline caused by altitude." says Timothy Hales at the University of Dundee, UK.

(1)、The underlined word “acclimatize” in Paragraph 2 is closest in meaning to______.
A、adapt B、ignore C、exist D、relax
(2)、What does the experiment done in China indicate?
A、The higher altitude you are at, the slower your brain will be. B、At 4,000 meters, the two subject groups show little difference. C、Memory tests are beneficial to relieving attention difficulties. D、Smart drug" largely reduces negative effects of altitude sickness.
(3)、According to the passage, the root cause of the cognitive effects lies in______ .
A、physical tiredness B、low oxygen content C、cognitive training D、extreme high altitude
(4)、What is the best title for the passage?
A、Fight High Anxiety B、Oxiacetam - A Magic Drug C、Keep Sharp at Altitude D、Problems on High-altitude Sites
举一反三

    Every evening, 15-year-old Rashida returns home from school,changes out of her uniform, and rushes to a neighboring farm to help her motherharvest vegetables. Her father is disabled, so the modest profit the two ofthem earn must cover food, clothing and other necessities for all sevenchildren and their parents. Despite having precious little time to study,Rashida is one of the top students at her junior secondary school. But with somuch responsibility on her small shoulders, she admits that it is sometimeshard for her to imagine a more promising future.

Last year, Rashida was invited to join 155 other girls at CamfedGhana's first Girls' Career Camp, a program designed to inspire girls growingup in the country's Northern Region to dream big, and to support them to pursuethose dreams. “We organized this camp because we wanted to let girls know thateven if they are struggling with poverty, their lives will not be defined bylimitations,” says Dolores Dickson, Camfed Ghana's Executive Director.

    Over the course of five days, the camp led the junior andsecondary school students through a range of experiences and career opportunities that were entirely new to them. Dr. Agnes Apusiga, a lecturer from the University of DevelopmentStudies, ran the workshop on goal-setting and career choices, describing theuniversities and training colleges in Ghana that could help them achieve theirdreams. Participants then visited the University for Development Studies, wherethey toured the medical school and science labs. Another highlight was aworkshop at the computer lab at Tamale Secondary School. Many of the girls hadstudied information technology from a book but had never before seen acomputer.

   “When the girls arrived at camp, they were not ambitious,because they didn't have any idea what the world held for them,” says EugeniaAyagiba, Project Officer with Camfed Ghana. “Many had scarcely traveled beyondtheir own villages.”

“I think the most important thing that happened at the camp isthat we opened a window of hope for a group of girls coming from backgrounds ofpoverty,” says Eugenia. For Rashida, who has been laughed at in the past by herschoolmates because of her father's disability, the experience was important.“She told one of the camp mentors(辅导员) that whenshe is at school, she often feels like a misfit, and she prefers to keep toherself,” says Eugenia. “But at the camp, it was different. She made friendswith girls who have similar struggles. She took part in every single activity,every single game. On the last day, she said to her mentor, ‘The camp haschallenged me to study hard. Now I see that there is light at the end of thetunnel.'

Dear Reader,

    Today I am going to ask you to support Wikipedia with a donation.

    Wikipedia is built differently from almost every other top 50 websites. We have a small number of paid staff,just twenty­three. Wikipedia content is free to use by anyone for any purpose. Our annual expenses are less than six million dollars. Wikipedia is run by the non­profit Wikimedia Foundation, which I founded in 2003.

    Wikipedia is driven by a global community of more than 150,000 volunteers — all devoted to sharing knowledge freely. Over almost eight years, these volunteers have contributed more than 11 million articles in 265 languages. More than 275 million people come to our website every month to access information,free of charge and free of advertising.

    But Wikipedia is more than a website. We share a common cause: Imagine a world in which every single person on the planet is given free access to the sum of all human knowledge. That's our commitment.

    Your donation helps us in several ways. Most importantly, you will help us cover the increasing cost of managing global traffic to one of the most popular websites on the Internet. Funds also help us improve the software that runs Wikipedia — making it easier to search, easier to read, and easier to write for. We are committed to increasing the free knowledge movement worldwide, by taking on new volunteers, and building strategic partnerships with institutions of culture and learning.

    Wikipedia is different. It's the largest encyclopedia (百科全书) in history, written by volunteers. Like a national park or a school, we don't believe advertising should have a place in Wikipedia. We want to keep it free and strong, but we need the support of thousands of people like you.

    Thank you,

Jimmy Wales

    One of the biggest problems when we are talking is the awkward silence. Encountering this situation is so uncomfortable that you would avoid meeting new people in the first place. In the past, I struggled with this and I even thought it had to do with my DNA or something… But later I learned that once you know how to keep those words flowing, you can meet and talk to anyone you like, which helps create great possibilities for friendship, fun and shared activities that you would otherwise have missed out on.

    After studying this in depth, I had different opinions and found that one of these common behaviors is the habit of filtering (过滤)--holding back from saying something until you've "checked" to make sure that what you're about to say is cool, impressive and interesting. Another problem is not learning to get in the mood for conversation. If you don't know how to change from subjects, then it can take a lot of time to warm up.

    It is the reflex (习惯性思维) that allows you to say whatever goes on in your mind. It's fun to realize that you're allowed to say whatever is on your mind. As long as you don't say anything that could land you in jail (监狱).

    All of the "Oh! That's interesting…" "Hmm, I've never heard of that" "Hmm, cool!" expressions are reactionary (保守的) bits of conversation that prove to the other person that you're really listening. This works 99% of the time. So, if you show some interest, they'll hang around and want to talk to you even more.

    Everyone knows that stories juice-up conversations, but most people only talk about stories of their own lives. When someone mentions something related to any of them, just tell the story, even if it's not from your life. The more interesting, stranger or more frightening they are, the harder they are to forget.

    The phone ID flashed,“Emergency Vet”.“ Oh no” I whispered. I could not lose Merlin now.

    Ron and I had tried to have children for a long time with depressing results. I threw myself into my work. Any maternal feelings I had were spent on Merlin.

    I couldn't wait to get home from work each night. I wanted to pick up that warm bundle of loving fur and nestle him. I wanted to sing “Rock-a-bye Merlin”,as I did every night as he would put his paws around my neck.

    Merlin was my comfort especially at times when I wondered if God was listening. But last night something had changed. Not only did I sing “Rock-a-Bye M1erlin”,but I asked, you 're gone?”

    Although Merlin was 19 years old, a senior in the· age of a cat, he didn't look or act that way. I didn't want to accept the fact that he was nearing the end of his lifetime. My job at the law firm was so demanding and stressful that I couldn't imagine getting through the day without Merlin waiting to greet me at home.

    I dialed the vet's number. I asked for my husband but he already left. Then I took a breath and asked the question that no one wants to ask,“Is my Merlin still alive?”The nurse said“ yes.”

    Ron came home and said that Merlin had almost no red blood cells left. White blood cells were replacing them. Merlin would need expensive transfusions most likely on a monthly basis. We both knew Merlin was running out of time. I asked Ron to drive me to the vet so I could say goodbye to my little boy cat but he was beat tired and it was late. Ron said if Merlin was still alive he next morning then he would take me to the vet.

    The next morning I called the vet. Merlin had survived the night. After driving to the vet, I went into the examining room. The nurse brought Merlin and placed him on an examining table on his side. His eyes were tightly shut. I thought he died already. I carefully edged my hand to reach his body. His body felt warm, but when I spoke his name there was no response. No response to his name or that I was there and that I loved him. I was extremely sad. In that examining room I felt helpless. I wondered how many people in an examining room felt as helpless as I did. Feeling driven to prayer I yelled, “God this isn't good enough. I need to see my Merlin the way I remember him, I need a miracle and I need it now!”

    At that moment, God granted a miracle. Merlin's favorite compliment entered my mind. I said, “Merlin, you are beautiful and you are gorgeous, do you hear me?”

One eye opened.

    I said “Gotcha”. I kept repeating those words.

    Merlin opened the other eye and, one limb at a time, got up. He was waiting for that phrase. He wanted to hear that he was beautiful and gorgeous again.

    Then I experienced another miracle.

    There was no sound in that examining room until Merlin started walking to me. From out of nowhere, or maybe from heaven, I clearly heard a song we sung in church often: “It Is Well With My Soul.” I remember叫thinking,“Yes, it is well with my soul. I got to see my little boy cat one more time.”

    Merlin walked to me. He put his face in mine, which he had never done before. He rubbed a circle around my face twice. Merlin said goodbye with his face and marked me for life.

    Ron appeared shocked that Merlin was up and had walked to me. I said to Merlin,“Tell God you are a good boy and how much we love you”and then handed him back to the nurse.

    Tears of gratitude poured forth in memory of a miracle. You see for nineteen years God spoke to me through a special cat named granted a miracle. That miracle gave me time to say goodbye.

    Charles Darwin lived an unusually quiet life. In 1842, Darwin and his wife Emma moved from London to Kent in southern England to have as little disturbance (烦扰) as possible. They already had two children then, and would go on to have eight more in the country.

    Darwin had very regular (有规律的) habits. He rose early and went for a walk. After breakfast he worked in his study until 9:30 am, his most productive time of the day, and then read his letters lying on the sofa before returning to work.

    At midday he would go for another walk with his dog, stopping at his greenhouse to inspect (查看) his experiments. Then he would go for another walk around an area of woodland. While walking on his "thinking path", Darwin would consider his unsolved scientific problems.

    After lunch he read the newspaper and wrote letters. His network of friends provided information from all corners of the world.

    The Darwins were not very strict parents and the children were always seen running wild. Their father worked patiently to a background of playful shouts and little footsteps walking past his study door.

After dinner Darwin played backgammon (a game for two people to play) with his wife. He once wrote, "Now the result with my wife in backgammon stands like this: she... has won only 2,490 games, while I have won, hurrah (a cheer of joy or victory), hurrah, 2,795 games!"

    Although he had poor health, Darwin continued to publish (出版)a lot of creative works until his final book in 1881. He died the following year, aged 73.

    Rather than a quiet space in the local churchyard, which he called "the sweetest place on Earth", Darwin was given a state funeral (国葬) in London's Westminster Abbey.
