    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

    I was just in France to visit my grandmother who is very dear to me. I don't get to cross the Atlantic very often, and she's now 96 years old, so every time I visit her, the two of us are very aware that it might be the last time we see each other.

    Last year, I did a series of short video interviews about her life. I asked her what it was like growing up with her father in the 1910s, and living alone with two young children. I asked her about her greatest memories, and her favorite books, foods, etc. I learned a lot of amazing new things about her I had never known before. These were very intimate conversations, which made me know her better.

    This year, I did not really have questions and I only had a great desire to make her know how much I loved her. I cooked for her and read her stories. I gave her a foot massage (按摩), which was her first ever! Before leaving, I was looking for a way to leave something meaningful behind besides the memory of our time together. Therefore, I wrote her five different love notes, and hid them in different places where I knew she would eventually find them.

    I left really joyously knowing that these cards would surely cheer her up after I left. She called me as I was travelling back to Paris to catch my plane back to the US and said, “I found your cards! By the time I discovered the last one, I was laughing out loud! Thank you so much, my sweetheart!” I smiled to myself, knowing she still had two more to go! It was Sunday, so my guess was that she had not checked her mailbox and had not yet driven her car!

    The Mokoko tribe (部落) lived on the wrong side of the island of two faces. The two sides, separated by a great cliff (悬崖), were like night and day. The good side was watered by rivers and was filled with trees and abundant food, while on the wrong side there was hardly any water or plants, and wild beasts crowded together. The Mokoko had the misfortune of having always lived there, with no way to cross to the other side. Their life was hard and they lived in permanent terror of the beasts.

    Along the edge of the cliff separating the two sides, a skinny but strong tree grew, with which they could build two poles. There was no doubt that the tribe would choose the great chief and doctor to use the poles. But when the two of them were given their chance to make the jump, they didn't dare to. They thought that the pole could break or it would not be long enough. They put so much energy into these thoughts that they gave in.

    But into that tribe were born Nam and Ariki, a pair of young hearts. One day, they decided to take up the poles. Nobody stopped them, but everyone did try to discourage them, trying to present how dangerous the jumping was, using a thousand explanations.

    "And what if what they say is true?" wondered the young Naru.

    "Don't worry. I am a bit scared too, but it doesn't look so difficult," replied Ariki, ever determined.

    "But if it goes wrong, it will be a terrible end," continued Naru, undecided.

    "Perhaps the jump will go badly. But staying forever on this side of the island surely won't work out well either."

    "You're right. Let's do it tomorrow."

    And on the next day, Naru and Ariki jumped to the good side of the island. When taking up the poles, while feeling their desire, the fear hardly allowed them to breathe. And while flying through the air, helpless and without support, they felt that something must have gone wrong and death awaited them. But when they landed on the other side, they thought the jump really hadn't been so bad after all.

    Recently whenever I turned on my computer or my mobile phone, news about the great effect of Hurricane Harvey on thousands of people caught my eyes. We saw many unfortunate events. However, there were also the bright news that confirmed the goodness of mankind. As a journalist, I wrote many human interesting stories during my career. That's why the story about the guys in the bakery caught my eyes.

    When the staff at a Mexican bakery chain in Houston were trapped inside the building for two days, they didn't sit there feeling sorry for themselves. They used their time wisely after flooding caused by Hurricane Harvey. While they were waiting for the eventual rescue that came on Monday morning, four decided to make as many loaves of bread as possible for their community.

    The flood water rose in the street outside. They took advantage of their emergency power supply to bake bread. They used more than 4,200 pounds of flour to create hundreds of loaves and sheets of sweet bread. Although the water kept rising, they continued baking to help more people. By the time the owner managed to get to them, they had made so much bread that we took the loaves to loads of emergency centers across the city for people affected by the floods.

    The store manager, Brian Alvarado, told The Independent, "Whenever a disaster occurs, nobody should just feel forlorn. Instead,we should take positive action to save ourselves and help others. Our acts of kindness will make a big difference."

    Guide dogs are going to be available for the children who are unable to see normally in the UK for the first time, as the age limit is to be removed. The Guide Dogs for the Blind Association is to begin training dogs to help blind people under the age of 16.

    The association says too many youngsters with impaired eyesight are lacking in independence. They have only a limited social life because of their disability. Giving some of them guide dogs at a younger age is intended to help them to widen their range of activities and to improve their sense of self-confidence and independence. Guide dogs for these teenagers will begin to be provided from next year. There has been an experimental project to test the use of guide dogs with younger people.

    Charlotte, aged 14, was among the youngest guide dog owners. She had been gradually losing her eyesight since the age of eight, and lost her eyesight completely this year. She has been assisted by a two-year-old guide dog. Charlotte used to have a long stick to help her move around, but having a guide dog allows her much more freedom and makes her feel safer.

    However, the association says there is a worryingly patchy supply of services for the young blind people across the UK, and it calls for a sharp increase in the number of guide dogs all over the country. As with adult blind people, only a small number of them are likely to be considered suitable for a guide dog. Most will continue to rely on extra help and training from education and social services.

    Scientists have found evidence of a link between social and economic status and childhood attention deficit disorder(ADHD)(注意力缺陷多动障碍)in the UK. A team led by the University of Exeter Medical School analysed data from the Millennium Cohort Study, a database of more than 19, 500 UK children born between 2000 and 2002 .The study was published in the Journal of Child Psychology and Psychiatry.

    Findings showed that more children with ADHD came from families below the poverty line than the UK population as a whole, with average family incomes for households whose study child was affected by ADHD at £324 per week, compared to £391 for those whose child was not. The study found the odds (机会)of parents in social housing having a child with ADHD was roughly three times greater than for those who owned their own homes.

    The team also found that the odds of younger mothers having a child with ADHD were significantly higher than for other mothers. Mothers with no qualifications were more than twice as likely to have a child with ADHD than those with degrees, and lone (孤独的)parents were more likely to have a child with ADHD diagnosis than households with two live-in parents.

    Information was gathered from surveys when the cohort children were nine months old, and at the ages of three, five, seven and eleven.

    Dr Ginny, of the University of Exeter Medical School, who led the study, said, "There is a genetic element to ADHD, but this study provides strong evidence that ADHD is also associated with a disadvantaged social and economic background. Some people believe that ADHD in children causes disadvantage to the economic situation of their family, but we found no evidence to support that theory. It's important to discover more about the causes of this disorder so that we can look towards prevention, and so that we can target treatment and support effectively. "
