    The Drink Your Body Needs Most

    I Our bodies are estimated to be about 60% to 70% water. Blood is mostly water,and
    our muscles,lungs,and brain all contain a lot of water. Water is needed to regulate body
    temperature and to provide the means for nutrients(滋养物)to travel to all our organs.
    Water also transports oxygen to our cells,removes waste,and protects our joints and
    organs.
    2 We lose water through urination(排尿),respiration(呼吸),and by sweating. If you
    are very active,you lose more water than if you do not take much exercise.Symptoms of
    mild dehydration(脱水)include chronic pains in joints and muscles, lower back pain,
    headaches, and constipation(便秘).A strong smell to your urine, along with a yellow
    color indicates that you are not getting enough water. Thirst is an obvious sign of
    dehydration and in fact,you need water long before you feel thirsty.
    3 A good rule of thumb(好的做法)is to take your bod犷weight in pounds and divide that
    number in half. That gives you the number of ounces(盎司)of water per day that you
    need.For example,if you weigh 160 pounds,you should drink at least 80 ounces of water
    per day.If you exercise you should drink another 8-ounce glass of water for every 20
    minutes you are active.If you drink coffee or alcohol,you should add at least an equal
    amount of water. When you are traveling on an airplane,it is good to have 8 ounces of
    water for every hour you are on board the plane.
    4 It may be difficult to drink enough water on a busy day.Be sure you have water handy at
    all times by keeping a bottle for water with you when you are working,traveling,or
    exercising.If you get bored with plain water,add a bit of lemon for a touch of flavor.There
    are some brands of flavored water available,but some of them have sugar or artificial
    sweeteners that you don't need.

    The amount of water your body needs per day is closely related________.
    A:in your body
    B:without water
    C:before long
    D:for a change
    E:on a busy day

    Some doctors think that you should drink a glass of water each morning. You should drink water before doing anything else.The temperature of the water should be similar to body temperature:not hot,not cold.Why should you drink this water?______(46).It helps clean out your kidneys.It prepares your stomach for digestion.______(47).After drinking water,the intestines can more easily take out nutrients from our food. And water helps us go to the bathroom more easily.
    Scientists suggest that people take in 1,600 milliliters of water each day.______(48).If you do,your kidneys will have to work much harder to eliminate it. It's better to drink some in morning and some in afternoon.______(49).And during meals,they think water dilutes the juices produced in our stomachs.This can interfere with normal digestion.
    Are you drinking enough water every day?Check the color of your urine.______(50).if your urine is very dark yellow,your probably need to drink more water. A little water each day could make you much healthier.

    _________(47)
    A:If it is light yellow,you are probably drinking enough
    B:Water can also help your intestines work better
    C:Some people think it's better to drink between meals
    D:Water helps your body in many ways

    本题考查的是对上下文之间意义关系的理解和对文章细节的把握。空格上一句问:“为什么要喝水呢?”而空格的下一句具体说明了喝水对人体有各种益处。因此这里应该是概括提出喝水有益健康,D与上下文联系最好。
    本题考查的是对上下文之间意义关系的理解和对文章细节的把握。空格的下一句是“饮水后,肠道能够更容易地从食物中吸取营养物质,也能让排泄更容易”,因此这里表述的应该是有关饮水与肠道的影响。
    本题考查的是对上下文之间意义关系的理解和对文章细节的把握。上一句说到“科学家建议每人一天应喝1 600毫升的水”,而空格后内容是“否则你的肾脏在处理这些水的时候会比较困难”,因此选项E与前后内容最符合。

    The Drink Your Body Needs Most

    I Our bodies are estimated to be about 60% to 70% water. Blood is mostly water,and
    our muscles,lungs,and brain all contain a lot of water. Water is needed to regulate body
    temperature and to provide the means for nutrients(滋养物)to travel to all our organs.
    Water also transports oxygen to our cells,removes waste,and protects our joints and
    organs.
    2 We lose water through urination(排尿),respiration(呼吸),and by sweating. If you
    are very active,you lose more water than if you do not take much exercise.Symptoms of
    mild dehydration(脱水)include chronic pains in joints and muscles, lower back pain,
    headaches, and constipation(便秘).A strong smell to your urine, along with a yellow
    color indicates that you are not getting enough water. Thirst is an obvious sign of
    dehydration and in fact,you need water long before you feel thirsty.
    3 A good rule of thumb(好的做法)is to take your bod犷weight in pounds and divide that
    number in half. That gives you the number of ounces(盎司)of water per day that you
    need.For example,if you weigh 160 pounds,you should drink at least 80 ounces of water
    per day.If you exercise you should drink another 8-ounce glass of water for every 20
    minutes you are active.If you drink coffee or alcohol,you should add at least an equal
    amount of water. When you are traveling on an airplane,it is good to have 8 ounces of
    water for every hour you are on board the plane.
    4 It may be difficult to drink enough water on a busy day.Be sure you have water handy at
    all times by keeping a bottle for water with you when you are working,traveling,or
    exercising.If you get bored with plain water,add a bit of lemon for a touch of flavor.There
    are some brands of flavored water available,but some of them have sugar or artificial
    sweeteners that you don't need.

    Paragraph 4__________
    A:Ounces of water needed per day
    B:Importance of water
    C:Composition of water
    D:Signs of dehydration
    E:Supply of water
    F:Necessity for bringing a bottle for water with you

    答案:F

    第三篇

    Look After Your Voice

    Often speakers at a meeting experience dry mouths and ask for a glass of water. You can solve the problem
    by activating the saliva in you mouth.First gently bite the edges of your tongue with your teeth.Or press
    your entire tongue to the bottom of your mouth and hold it there until the saliva flow.Or you can imagine that
    you are slicing a big juicy lemon and sucking the juice.
    Before you begin your talk,be kind to your voice.Avoid milk or creamy drinks which coat your throat.
    Keep your throat wet by drinking a little sweetened warm tea or diluted fruit juice.
    If you sense that your are losing your voice,stop talking completely.Save your voice for your speech.
    You may feel foolish using paper to write notes,but the best thing you can do is to rest your voice.If you
    need to see a doctor,perhaps you can get some advice from a professional singer. In the meantime,do not
    even talk in a low voice.
    What about drinking alcohol to wet your throat?I advice you not to touch alcohol before speaking. The
    problem with alcohol is that one drink gives you a little confidence.The second drink gives you even more
    confidence.Finally you will feel all-powerful and you will feel you can do everything,but in fact your brain
    and your mouth do not work together properly.Save the alcohol until after you finish speaking.
    Perhaps you want to accept the advice,but you may wonder if you can ever change the habits of a life-
    time.Of course you can.Goethe,who lived before indoor skating rinks or swimming pools,said,"We learn
    to skate in the summer and swim in the winter."Take this message to heart and give yourself time to develop
    your new habits.If you are willing to change,you will soon be able to say that you will never forget these
    techniques because they became a part of your body.

    What is the writer's advice about alcohol before you give a speech?
    A:Drink a little of it to feel all-powerful.
    B:Don't drink it.
    C:Dilute it with water.
    D: Drink it two hours before you make a speech.

    答案:B
    解析:
    在文章第一段中,作者提到三种解决讲话时口干的方法,分别对应A、B、C选项。故 选D。
    由文章第三段第三句“...but the best thing you can do is to rest your voice.”可知,答案 为A。
    由文章第四段可知,作者忠告演说者在演说之前千万不要饮酒。故选B。
    文章最后一段中歌德的原话是“We learn to skate in the summer and swim in the winter",A项与歌德的说法最接近。
    作者在最后一段引用歌德的话想证明,一个人在一生中养成的习惯如果想改还是可以 改的。故选C。第5部分:补全短文
