How to Care for Your Ears?

        Ears not only let us hear, but they alsoplay a role in maintaining our balance, which is vital to our ability to function in daily life. Yet, we ignore them. We can't even see our ears, exceptin a mirror. We take for granted what they do for us day in and day out－untilwe notice something's wrong, such as when an earache strikes or when we starthaving to ask people to repeat what they say.{#blank#}1{#/blank#}

◆ Clean your ear with a washcloth－coveredfinger only.

      Never put anything inside your earcanal, including cotton swabs (药签).{#blank#}2{#/blank#}．

◆ Leave earwax(耳垢)alone.

      Wax is your ear's way of eliminating(消除)anything foreign that gets into the ear canal.{#blank#}3{#/blank#}If you find you have too much earwax,use a few drops of earwax remover(去除剂) in the canal. After a few minutes,wash the ear with warm water.

◆ Avoid noisy places.

      Rock concerts and construction sites are just a few places that frequently have noise levels that can damage hearing.Any place where you have to shout to be heard should be avoided.

      Be careful not to play MP3 too loud, especiallyif using earphone.

◆Be careful with illness andmedications.

      Respiratory (呼吸的) illnesses should be treated to avoid their spread to the ears. Certainmedications can damage hearing, so follow the directions carefully beforetaking them.

      See your doctor if you suffer fromsudden hearing loss or hear noises in your head.

    Scientists are debating how to limit their newly-discovered power to change genetic structure (结构). Scientists already modify the genes (基因) of farm animals and agricultural plants to make them more productive or stronger. But now they can also change genes in wild animals and plants. These genes would continue into later generations. For example, it may be possible for scientists to remove from existence the kind of mosquitoes, small flying insects, that carry the Zika virus. They might also be able to permanently remove species (物种) of plants and animals that are damaging to other species.

    In a report published last week, the U. S. National Academies of Sciences, Engineering and Medicine (NAS) said it supports continued research on this kind of gene control. But it warned that it is not possible to know what will happen when these changed plants and animals are released (释放) into the wild.

    Sixteen biologists, ethicists (伦理学家) and policymakers are on an NAS committee that is examining the issue. They say that there is value to the new technology. But, they say, there is not enough evidence to support the release of modified organisms (生物体) from the laboratory into nature.

    Many people would support stopping mosquitoes and rats from carrying diseases. But scientists say we must understand the possible scientific, ethical, legal and social results of such action before we decide whether to take it. Gene modification is spread through reproduction (繁殖).

    Changed genes will continue to spread as long as an animal or plant continues to reproduce. They cannot be limited to a farm or kept within a country's borders. Scientists are wondering what may happen if a modified organism mates with another species. They are not yet sure how the modified genes would affect the other species. It is possible that those genes could harm those creatures or even lead to their disappearance from our planet.

    Everybody sleeps, but what people stay up late to catch or wake up early in order not to miss varies by culture？

    From data collected, it seems the things that cause us to lose the most sleep, on average, are sporting events, time changes, and holidays.

    Around the world, people changed sleep patterns thanks to the start or end of daylight savings time. Russians, for example, began to wake up about a half-hour later each day after President Vladimir Putin shifted the country permanently to "winter time" starting on October 26.

    Russia's other late nights and early mornings generally correspond to public holidays. On New Year's Eve, Russians have the world's latest bedtime, hitting the hay at around 3:30 a. m.

    Russians also get up an hour later on International Women's Day, the day for treating and celebrating female relatives.

    Similarly, Americans' late nights, late mornings, and longest sleeps fall on three-day weekends.

    Canada got the least sleep of the year the night it beat Sweden in the Olympic hockey (冰球) final.

    The World Cup is also chiefly responsible for sleep deprivation. The worst night for sleep in the U. K. was the night of the England-Italy match on June 14. Brits stayed up a half-hour later to watch it, and then they woke up earlier than usual the next morning. Thanks to summer nights, the phenomenon in which the sun barely sets in northern countries in the summertime. That was nothing, though, compared to Germans, Italians, and the French, who stayed up around an hour and a half later on various days throughout the summer to watch the Cup.

    It should be made clear that not everyone has a device to record their sleep patterns; in some of these nations, it's likely that only the richest people do. And people who elect to track their sleep may try to get more sleep than the average person. Even if that's the case, though, the above findings are still striking. If the most health-conscious among us have such deep swings in our shut-eye levels throughout the year, how much sleep are the rest of us losing?

Three Feet From Gold

    Darby's uncle was caught by the “gold fever” in the gold-rush days, and went west to dig and grow rich. After months of labor, he was rewarded by the discovery of the shining ore (矿石). He needed machinery to bring the ore to the surface. So, with the “strike”, he returned home. And with the help of Darby, he borrowed a lot of money. After buying the machinery and having it shipped, Uncle and Darby went back to work the mine.

    The first car of ore was mined. And the returns proved they had one of the richest mines in Colorado! Down went the drills! Up went the hopes of Uncle and Darby!

    Then something happened! The vein (矿脉) of gold ore disappeared! They drilled on, but all in vain. Finally, they decided to quit and sold the machinery to a junk man for a few hundred dollars. The junk man called in a mining engineer to look at the mine and do a little calculating. The engineer's calculations showed that the vein would be found just three feet from where the Darbys had stopped drilling! The junk man took millions of dollars in the vein, because he knew enough to seek expert's advice before giving up.

    Most of the money which went into the machinery was borrowed through the efforts of Darby, who was then a very young man. The money came from his relatives because of their faith in him. He paid back every dollar of it, although he was years in doing so.

    Long afterward, Mr. Darby made another discovery that desire can be changed into gold. This discovery came after he went into the business of selling life insurance. Remembering that he lost a huge fortune, for he stopped three feet from gold, Darby profited by the experience in his chosen work, saying to himself, “I stopped three feet from gold, but I will never stop because men say 'no' when I ask them to buy insurance.”

    Darby sold more than a million dollars in life insurance annually. He owes his “stickability” to the lesson he learned from his “quitability” in the gold mining business.

    The most important thing to keep in mind when going into high school is to be yourself. Besides, I don't know what your middle school was like, but high school teachers will not care about things such as how much homework you already have in one night. It's best to just learn to deal with things and manage your time wisely so you can achieve everything you need to

    I think almost every kid feels both nervous and excited before their first day. You will probably love it. I know I did. You should join some sports or activities that will make your high school experience more enjoyable. Good luck!

    Eddie, Aged 20

    When I started high school I was really nervous too, especially since I had been homeschooled all through middle school and didn't really know anyone. I suppose the best advice would be to just relax. The first couple of days can be a little bit hard, but things will become easier before you know it.

    I'm not going to lie. The first day is kind of frightening (令人恐惧的). But you'll get used to it. Don't be afraid of anyone. Upperclassmen will pick on you more if you let them know you're afraid. Just take it easy. Making some friends and staying with them will greatly help you get used to high school quickly. After the first week it's really not bad at all. Don't worry.

    I sat with my friend in a well-known coffee shop in a neighboring town of Venice. As we enjoyed our coffee, a man called the waiter and placed his order, “Two cups of coffee, one on the wall.” We got interested and observed that he was served with one cup of coffee but he paid for two. As soon as he left, the waiter attached a piece of paper to the wall saying “A Cup of Coffee.” Similar occasions took place twice while we were there. It seemed that this gesture was quite normal at this place. However, it was something unique and confusing for us.

    After a few days, when we again enjoyed coffee there, a man entered. The way this man was dressed did not match the standard or the atmosphere of this coffee shop. Poverty was evident from his looks. As he seated himself, he looked at the wall and said, “One cup of coffee from the wall.” The waiter served coffee to this man with respect and dignity. The man had his coffee and left without paying. We were amazed to watch all this when the waiter took off a piece of paper from the wall and threw it in the dustbin.

    Now it was no surprise for us; the matter was very clear. The great respect for the needy shown by people in this town moved us to tears.

    Coffee is not a necessity. However, the point is that when we take pleasure in any blessing, maybe we also need to think about those people who also appreciate that specific blessing but cannot afford.

    Note the waiter, who gets the communication going between the affording and the needy with a smile on his face. Think about the man in need: he enters the coffee shop without having to lower his self-dignity; he has a free cup of coffee without asking or knowing about who has given this cup of coffee to him; he only looked at the wall, placed an order for himself, enjoyed his coffee and left. Besides, we need to remember the role played by the wall that reflects the generosity and care of people in this town.
