    This past summer I went on a journey to Canada's Arctic with Students On Ice. When I left Calgary I wondered what I would find what I would learn and who I would meet. On the trip to Ottawa I was wrapped in a blanket of uncertainty and excitement. But when I first met the group of students, scientists and leaders, I knew that l didn't have anything to worry about. The group was amazingly receptive and I was soon part of a big family setting out on an amazing adventure—an adventure of a lifetime!

    When we reached the Arctic I saw a vast Land that appeared untouched and original. I was surprised by its great size and beauty and my senses were repeatedly shocked and amazed. I stood on the Kapitan Khlebnikov and saw twelve polar bears. They walked in search of seal holes, and patiently waited for a meal. I learned that polar bears are successful only one out of every twenty hunting attempts.

    However, I learned that the Arctic and its people are being threatened by pollution and global warming. I learned that pollutants are carried by ocean and air and have a bad effect on all Arctic people. I learned that global warming has put polar bears at risk because a warmer climate means that they have a shorter time to hunt seals on the ice.

    The trip was a feast (盛宴) for the senses. I have learned more about our environment, and particularly how alive and interesting the Arctic is and why it is so important to take care of it. I learned pollution, ignorance of individual and global problems need to be solved. The Arctic deserves to be preserved. My trip with Students On Ice has made me more determined to try to ensure that I do not leave harmful footprints on either Earth or its people.

    Scientists have found an unexpected use for virtual reality headsets (耳机). The devices (装置), widely used by computer gamers, show pictures that can be used to test the navigational (导航的) skills of people, who were thought to be at risk of dementia (痴呆). Those who do worse in the tests will be the ones more likely to develop Alzheimer's disease later in life, scientists now believe.

    The discovery that the loss of navigational skills was associated with Alzheimer's was made several years ago by Dennis Chan and his colleagues based at several centers in the UK. These studies used computers to test navigational tasks. But now scientists plan to take their tests to a new level with the use of the virtual reality headsets in which wearers are placed in man-made environments through which they must navigate.

    Around 300 people, aged between 40 and 60, will be arranged to participate in the study. Some will have a gene that puts them at risk of the condition or will come from a family with a history of Alzheimer's. Not all will certainly be affected by the disease, however. Chan's project aims to find out who will. Wearing the headsets, participants will be asked to navigate their way through a series of different environments and then remember the details.

    Researchers recently pointed out the significance of a tiny area of the brain known as the entorhinal cortex (an important memory center in the brain). It acts as a center in a widespread brain network that controls navigation. This now appears to be the first part of the brain that seems to be easily harmed by Alzheimer's.

    The goal of the work is to help people as they develop the disease. "So far, drug trials for Alzheimer's have been applied when people have already got dementia, by which time considerable damage to the brain has already occurred," Chan told the Obsenver. "If we can develop drugs and use them earlier, for example, before the disease has spread beyong the entorhinal cortex, then this would have the potential to prevent the dementia."

    After decades of cat-and-mouse between athletes and the word anti-doping agency (WADA), athletes found what they must have believed to be the ultimate (终极的) doping agent: their own blood. To enhance athletic performance with your own blood, you draw your blood and store it in a freezer. Your body compensates by creating more blood. Then, months later, just before a competition, you can re-inject (注射) the old blood for a boost. As the red-blood-cell count goes up, so does an athlete's ability to absorb oxygen. The more oxygen you get with each breath, the more energy your body is able to bum and the better you are able to perform.

    Although the enhancement is small compared to actual drugs, it can be the difference between a gold medal and a silver medal. Best of all, "extra blood" was never something WADA tested for.

    But WADA wasn't going to sit by and be fooled. What it came up with in response might be a solution to stop doping once and for all: an athlete biological passport (ABP). The idea is to record some biological features of an athlete through testing done at regular intervals. The biological passport's partial implementation (实施)—recording blood and steroid levels—began in January 2014.

    When all necessary biological features are finally combined, WADA will no longer need to worry about finding new methods to detect a drug. It will only have to detect (检测) resulting changes in the body. In the case of blood doping, if the athlete's normal red-blood-cell count is, say, 47%, but then is found to be 51% after a competition, cheating may have been involved.

    WADA is confident that the biological passport could even prevent genetic changes—the ultimate, ever-lasting enhancement—which are surely coming next. If an athlete inserts a performance enhancing gene, it will probably leave detectable changes in the body, that would differ from the athlete's feature in the biological passport.

    Taking care of a sick loved one can put stress on your health. When taking care of other persons, you may ignore your own physical needs. You may find that your health is failing. If you fall ill, you won't be able to help.       .

    Eat well. When things seem out of control, you may have no time to focus on good eating habits. You may not eat much;       . Both of those put stress on you. Try to eat as healthily as you can, even if sometimes you have to rely on simple meals like salads.

    Try to get enough sleep. Sleep can also be difficult when you're caring for a loved one. You may be too worried to sleep at times,       . Not getting enough sleep can make you less effective in the task. Therefore, try to get as much as you can.

    Take time to exercise. Exercising will also help you keep healthy while you're caring for a loved one. Exercise can reduce your stress level.       . So you'll need to find ways to work it into your schedule. You can take a short walk a couple of times or do yoga at home.

          . It can be easy to overlook the health problem in yourself when you're caring for someone else. If you fall ill, that does not do anyone good. So it's best to make sure you're in good health.

A. or you may end up eating junk food

B. or the task may interrupt your sleep

C. Don't ignore signs of illness in yourself

D. It can help you get recovered from illness

E. Therefore, it is important to take care of yourself

F. However, it can be difficult when you're taking care of a loved one

G. The best plan is to visit the doctor regularly to make sure you're in good health

    I'm currently at a unique university, an inclusive one where 46 speech and hearing 1 students graduate each year. I have been working with these students to help them get clear on their career goals.

    Today, an 2 thing happened. One girl came at around 11: 30 am and sat down. I started with what we usually do. She can speak but cannot 3 or lip-read. So she started speaking in Tamil. When I managed to tell her that I couldn't speak Tamil, she spoke English.

    I 4 asking one question, and she went on for 10 minutes 5, and in Tamil. I understood a 6 of words here and there, so I knew she was not saying something 7 to what I asked. I was just looking straight in her eyes and smiling. I kept on 8 her without saying a word. This went on for an hour and a half!

    Then after a long 9, I told her to get back on 10 with another question. And then she shared for another half an hour straight! The 11 time I was just looking in her 12 but never 13 down.

    I had absolutely no 14 what she spoke for these hours, but what I knew was that I was listening to 15 she was sharing and also started understanding a bit in 16. Several times, I would 17 with a simple question: Are you happy? And she would 18 on.

    I was 19 happy because I saw her smiling in the end. And then, I just 20 and hugged her and she was smiling even wider.

    Fewer than one in seven people can        ( correct) identify common washing symbols while a        (three) of people admit they never check instruction labels (标签). Some seven in ten say they ever had machine-washed clothes that should        (go) to the dry cleaners because they failed to look at the labels.

    The ignorance about        clothes should be cleaned can cost families thousands of pounds, according to a sample test of householders by a school uniform supplier.

    Men are the worst offenders with more than three quarters always using the same program on a washing machine regardless of the instructions. Almost half of        (woman) used just three programs.        is said that the lack of understanding over symbols is destroying thousands of pounds worth of clothing        (treat) improperly.

    While almost eight        ten people believe it is important to check the labels on their clothes, less than half look at them when        (buy) new clothes. Some nine out of ten said they were unaware that some clothing should never be put in the drier.

    The labels are there to show how clothes should be treated. This        (help) information can save time and ensure clothes to last longer.
