Doctors in hospital emergency rooms often see accidental poisonings. A frightened parent arrives with a child who swallowed a cleaning liquid. Or perhaps the harmful substance is a medicine. Or it might be a chemical product meant to kill insects. These are common causes of accidental poisoning.

    In cases like this, seek medical help as soon as possible. Save the container of whatever caused the poisoning. And look on the container for information about anything that stops the effects of the poison. Save anything expelled from the mouth of the victim. That way, doctors can examine it.

    Millions of people know a way to save a person who is choking on something trapped in the throat. The method is commonly known as the Heimlich Maneuver or abdominal thrusts(腹部按压), which you can do by getting directly behind a sitting or standing person. Put your arms around the victim's waist. Close one hand to form a ball. Place it over the upper part of the stomach, below the ribs. Place the other hand on top. Then push forcefully inward and upward. Repeat the abdominal thrusts until the object is expelled from the mouth. For someone who is pregnant or very fat, place your hands a little higher than with normal abdominal thrusts.

    Red Cross experts say taking these steps can save many lives. But they also warn that abdominal thrusts are not for people who have almost drowned. They say use of the method could delay other ways to re-start breathing in the victim. Abdominal thrusts should be used only in cases where a near-drowning victim is choking on an object.

    To learn more about first aid, ask a hospital or organization like a Red Cross or Red Crescent Society for information. There may be training classes offered in your area.

阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。

    Are you sometimes a little tired and sleepy in the early afternoon? Many people feel this way after lunch. They may think that eating lunch is the cause of the sleepiness. Or, in summer, they may think it is the heat. However, the real reason lies inside their bodies. At that time—about eight hours after you wake up—your body temperature goes down. This is what makes you slow down and feel sleepy. Scientists have tested sleep habits in experiments where there was no night or day. The people in these experiments almost always followed a similar sleeping pattern. They slept for one long period and then for one short period about eight hours later.

    In many parts of the world, people take naps (小睡) in the middle of the day. This is especially true in warmer climates, where the heat makes work difficult in the early afternoon. Researchers are now saying that naps are good for everyone in any climate. A daily nap gives one a more rested body and mind and therefore is good for health in general. In countries where naps are traditional, people often suffer less from problems such as heart disease. Many working people, unfortunately, have no time to take naps. Though doctors may advise taking naps, employers do not allow it! If you do have the chance, however, here are a few tips about making the most of your nap. Remember that the best time to take a nap is about eight hours after you get up. A short sleep too late in the day may only make you feel more tired and sleepy afterward. This can also happen if you sleep for too long. If you do not have enough time, try a short nap—even ten minutes of sleep can be helpful.

    How similar are language and music

    Language is part of our daily lives, no matter where we live m the world.{#blank#}1{#/blank#}Both language and music play a huge role in our culture and here are some of their similarities.

    ·Both language and music have a writing system.

    In English we record language using the alphabet, which is a collection of letters. Similarly, we use notes to keep a record of music. Musicians read notes and create meaning in the form of music{#blank#}2{#/blank#} By writing pieces of text or music, we are able to share experiences through time. We can read the ideas or hear the composition of someone who lived hundreds of years ago.

    {#blank#}3{#/blank#}

    You can make a good guess at where someone is from by listening to the language they use. In the same way, we know that styles of music are different around the world, giving us the opportunity to explore many different cultures through their music and providing us with music for every situation.

    In America, the number of people killed in car crashes in 2016 was above 40, 000 for the first time in a decade, data released on Wednesday shows.

    "Americans believe there is nothing we can do to stop crashes from happening, but that isn't true. We are behind the rest of the developed world in addressing highway fatalities(死亡). We just haven't been willing to do what needs to be done, "said Deborah A. P. Hersman, president of the National Safety Council.

    The National Safety Council data shows a 6 percent increase in deaths in 2018 when compared with 2015 and a 3 percent increase in the number of miles Americana drove in 2016.

    "Motor vehicle fatality numbers have been ringing the alarm for two years, "Hersman said." Unfortunately, we have been blind to the data and the killings on our roadways. If we fail to take action, the death tell will continue to rise. "

    "The trend is clear：After years of progress, highway deaths are heading in the wrong direction, "said Jonathan Adkins, a state safety official.

    The number of people killed reached a record low of 32, 675 in 2014, according to NHTSA statistics. That record followed a fairly steady downward track for the past six years that experts attributed it primarily to safety features that have been built into cars and trucks.

    Safety advances including increased seat-belt use, air bags, anti-lock braking, stability controls and electronic warnings and cameras.

    The bad economy and high gas prices also influenced the reduction in deaths. Now, with unemployment and gas prices both low, more people are driving for work and pleasure trips.

    "It's not just that Americans drive more miles when the economy improves; it's the kind of miles they drive,"said Adrian Lund, president of the Insurance Institute for Highway Safety.

The Tokyo Olympics have been postponed until 2021. That delay offers a chance for reflection. The International Olympic Committee wants to make the games more popular with young people. To that end, it is introducing new events, such as skateboarding, surfing and climbing. Why not go further and let national teams compete at video games? Electronic sports such as "Fortnite", are vastly more popular than strange Olympic sports like curling (冰壶). In fact, they are more appealing than most mainstream sports. Only 28% of British boys aged 16-19 watch any traditional live sports; 57% play video games.

Some may complain that e-sports are not proper sports. Many parents, observing their teenagers sitting on the sofa all day shouting "Quick, pass me the shotgun!" at a screen, would agree. Yet video games are highly competitive, with professional teams that play to packed stadiums. There are perhaps only 200 tennis stars in the world who can make a living from playing in major competitions. By contrast, "League of Legends", a fantasy game played by teams of five, supports over 1,000 on good wages. Its World Championship final last year was watched by 44 million people.

Those against e-sports offer moral objections, too. They are addictive. Prince Harry has called for "Fortnite" to be banned for this reason. They are violent. At a time of global disharmony, it is bad idea to make virtual (虚拟的) killing an Olympic sport. The Olympics aim to promote peace.

Neither of these arguments is convincing. The idea that an activity, rather than material, can be addictive is controversial among doctors, as is the existence of a causal (因果的) link between gaming and violence. And the belief that warlike sports have no place in the Olympics is hard to agree with history. Wrestling was introduced in 708 BC. It is still there.
