    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

    English has now achieved global status (position). Whenever we turn on the news to find out what's happening in East Asia, or Africa, or South America, or anywhere, local people are being interviewed and telling us about it in English.

    Indeed, if one looks at the facts about the amazing reach of the English language, he or she would be surprised. English is used in over 90 countries as an official or semi-official language. English is the working language of many international colleges as well as of most international research scientists. It is believed that over one billion people worldwide are learning English now.

    One of the most remarkable sides of the spread of English around the world has been the extent (程度) to which Europeans are accepting it as their language. English is spreading from northern Europe to the south and is now firmly set up as a second language in countries such as Sweden, Norway, Netherlands and Denmark. If one visits any of them, it would seem that almost everyone there can communicate with ease in English.

    Recently, a special survey of Europeans' use of languages has just been published. The report said that English is the most widely known foreign language now, with 43% of Europeans saying they speak it and that Sweden now holds the most of English speakers, with over 89% of the population. What's more, English is the language rated as the most useful language to know, with over 77% of Europeans who do not speak English as their first language considering it useful.

    English has without doubt become the global language.

    You probably know who Marie Curie was, but you may not have heard of Rachel Carson. Of the outstanding ladies listed below, who do you think was the most important woman of the past 100 years?

    Jane Addams (1860-1935)

    Anyone who has ever been helped by a social worker has Jane Addams to thank. Addams helped the poor and worked for peace. She encouraged a sense of community(社区) by creating shelters and promoting education and services for people in need. In 1931, Addams became the first American women to win the Nobel Peace Prize.

    Rachel Carson (1907-1964)

    If it weren't for Rachel Carson, the environmental movement might not exist today. Her popular 1962 book Silent Spring raised awareness of the dangers of pollution and the harmful effects of chemicals on humans and on the world's lakes and oceans.

    Sandra Day O'Connor (1930-present)

    When Sandra Day O'Connor finished third in her class at Stanford Law School in 1952, she could not find work at a law firm because she was a woman. She became an Arizona State Senator(参议员) and in 1981, the first woman to join the US Supreme Court(高等法院). O'Connor gave the deciding vote in many important cases during her 24 years on the top court.

    Rosa Parks (1913-2005)

    On December 1, 1955, in Montgomery, Alabama, Rosa Parks would not give up her seat to a white passenger. Her simple act landed Parks in prison. But it also set off the Montgomery bus boycott. (抵制行动) It lasted for more than a year, and kicked off the civil-rights movements. "the only tired I was, was tired of giving in." said Parks.

    For the past two years I have been travelling and living abroad. Home has become more of a feeling than a place. I feel at home when I am with my family in London, but I also feel at home in Italy with friends I love. Home is no longer a picture of a house with a front door and some windows. It is more complicated than that.

    This is one of the reasons that celebrating the new year has become very important for me. I do not care about "New Year's resolutions (愿望)"—living abroad has made me constantly reconsider what kind of person I want to be and how I will live my life, so I don't feel the need to plan for change: I live for change.

    New Year's Eve has become my time to reconnect with the friends that makes me feel at home. Every year we try to reunite wherever we are and remember the time when we knew each other so well that we felt like a family. It is a moment to reconnect and get to know each other again. Last year, we travelled to a cottage in Ireland where we had no internet and no neighbours. In the middle of the countryside, away from our big and constantly changing lives, we were able to become like a little family again.

    This year, we went to Barcelona. It was a very big change. We were surrounded by culture and life and joy. There were bars and parties. It was different, but one thing stayed very much the same-I felt at home again and we felt like a family again.

    A lot of people feel that New Year's Eve cannot live up to expectations. Ideas such as the "New Year's kiss" and "resolutions" create a lot of pressure for people to have a night to remember, a night that will change their lives and perhaps make the next year one worth living. I think those people are missing the point. If Christmas is about family, why can't New Year be about friends?

I'd say I quarrel with my parents a lot.Throughout high school,I was always jealous(羡慕的) of some of my friends who didn't seem to have those problems at home,but I've come to see over the years that no one's situation is perfect.

Part of the reason I work all week during my break,in addition to the money,of course,is to be out of the house to avoid continuing quarrels.At work,I eat lunch with my friend Krysta every day,but the best days are when our favourite workmate,Lucy,is on her lunch break at the same time as us.Her funny way of storytelling always has us laughing happily,and although she is almost old enough to be our mom,she feels more like a best friend.

A few weeks ago,however,there was a change in our lunch conversation,and the story she told had us in real tears instead of our usual tears of laughter.A more serious topic had come up,and she sat us down to explain the importance of forgiveness(宽恕),especially when it came to our parents.Telling stories of her troubled relationship with her mother,she changed my whole outlook on life and my feelings towards my parents.She reminded(提醒) us that no matter how much resentment(怨恨) we're feeling in a moment of anger,we have to be thankful for the support they provide and learn to forgive everything else.

This week I've spent my break at home,having very small quarrels and lots of quality time together with my parents.Sometimes you need a reminder to make you realize how important it is to let go of past resentment and work to repair broken relationships.My workmate's moving stories not only brought me to tears in the break room at work that day but served as that wake-up call as well.
