    根据下面资料,回答
    Germs are everywhere. You can′t see them, but they are on your desk, on your computer, and even in the air!
    Like people, germs move around the world. They fly with us on planes. When food, clothes, and other things travel around the world, germs travel, too. Some germs are safe, but some are dangerous. Germs cause illnesses like colds and the flu.
    Warmer Weather Brings Germs
    The world′s weather is changing. Cooler countries are getting warmer, so insects from hot countries can move there. Some of these insects, like mosquitoes, carry dangerous germs. These germs cause headaches, fever, and can even kill people.
    Under Your Skin
    Your skin protects you from germs. It stops some germs, but not all. They can enter your body when you eat, or when you have a cut. Germs are on your hands, too. They enter your body when you touch your eyes, nose, or mouth.
    Your immune system (免疫系统) protects you, too. When germs get inside your body, your immune system finds and kills them. Special cells (细胞) move around your body and fight germs. They help you stay healthy. Other cells make antibodies. Antibodies help your body find and stop germs.
    What can you do to fight germs? You should wash your hands with soap and water. Soap kills many germs, and water washes them away.
    Please fill in the blank with proper phrases to complete the title of the last paragraph.

    Diabetes(糖尿病)and Eye Damage

    Over 2 million Canadians have diabetes.It is the leading cause of blindness in North
    Americans under 65 years of age.Diabetes is a condition where the body either cannot
    produce enough insulin(胰岛素)or cannot respond properly to insulin. Insulin is important
    because it moves glucose(葡萄糖),a simple sugar, into the body's cells from the blood.
    The food people eat provides the body with glucose,which is used by the cells as a source
    of energy.If insulin isn't available or doesn't work correctly to move glucose from the blood
    into the cells,glucose will stay in the blood,leading to high blood sugar levels.
    High blood sugar levels damage the blood vessels,including the tiny blood vessels in
    the eye.This leads to an eye disease known as diabetic retinopathy(糖尿病型视网膜病).
    The retina(视网膜)is an area at the back of the eye that changes light into nerve signals.
    With diabetic retinopathy,some blood vessels in the retina are lost,and some of the other
    blood vessels begin to"leak"blood.This causes the retina to swell,and gradually cuts off
    its supply of oxygen and nutrients(滋养物).Eventually , the retina starts to grow new
    blood vessels to replace the damaged ones.Unfortunately,these new vessels are not as
    strong as the old ones.They are more likely to break,causing bleeding in the eye.
    At first,people with diabetic retinopathy will not notice any symptoms.As the disease
    gets worse , they may notice blurred(模糊的)vision, black spots or flashing lights. As
    time goes on,it can progress to blindness.Everyone with diabetes is at risk for diabetic
    retinopathy,and the risk increases the longer you've had diabetes.
    Fortunately,you can reduce your risk.If you do not have diabetes,but think you may
    be at risk for this condition,visit your doctor to be screened for diabetes.If you do have
    diabetes:
    Have frequent eye check-ups.
    Make sure that you monitor your blood sugar frequently and use your medications as
    recommended by your doctor. There is evidence to show that keeping your blood sugar
    under tight control can slow down eye damage.
    If you have high blood pressure,follow your recommended diet and medications to
    keep it under control.If you are not sure whether you have high blood pressure,or whether
    your blood pressure is under control,discuss this with your doctor.

    With diabetic retinopathy,the damaged blood vessels in the retina
    A:are stronger than what they used to be.
    B: cannot be properly replaced.
    C:are more likely to break than the new ones.
    D: may return to normal again.

    One of the things we all know about sleep is that we are Unconscious in sleep,We do not know what is going on around us.But that do.esn′t mean the body stops all activity.The important organs continue to work during sleep,but most of the body functions are slowed down.
    For example,our breathing becomes slower and deeper.The heart beats more slowly,and the blood pressure is lower.Our arms and legs become limp(柔软的)and muscles are at rest.It would be impossible for our body to relax to such an extent if we were awake.So sleep does for us what the?most quiet rest can not do.

    Bone Marrow Transplantation

    Bone marrow is the spongy tissue inside some of your bones,such as your hip and thigh bones. It contains immature cells,called stem cells.The stem cells can develop into the red blood cells that carry oxygen through your body,the white blood cells that fight infections,and the platelets that help with blood clotting.
    If there is a problem with your bone marrow,a transplant can give you healthy new marrow. You could need a transplant because of a disease,such as bone marrow diseases or cancers like leukemia kemia or lymphoma.Or you might need one if a strong cancer treatment kills your healthy blood cells.
    People with cancer sometimes donate bone marrow before treatment to be transplanted later. But often the new marrow comes from a donor,either a close family member or someone unrelated.
    The healthy cells for a transplant can come from three sources:bone marrow;peripheral (circulating) blood that has an increased number of healthy blood-forming cells(also called peripheral blood stem cells or PBSC);umbilical cord blood that is collected after a baby is born.
    If you need an allogeneic transplant,your doctor will look for a marrow donor or cord blood unit that matches your HLA tissue type.HLA stands for human leukocyte antigen,a markei your immune system uses to recognize which cells belong in your body and which do not.
    Before your body can receive the healthy cells,the diseased cells must be destroyed.This is done using chemotherapy and sometimes radiation. The destruction of diseased cells is called a preparative regimen or a conditioning regimen.
    On the day of transplant,the cells from the marrow donor or cord blood unit are infused intravenously(go into your body through a large vein).These healthy cells move into the spaces inside your bones where they create new marrow. They grow and make healthy new red blood cells,white blood cells,and platelets.

    Before receiving healthy cells,diseased cells must_________.
    A:undergo chemotherapy
    B:go through radiation
    C:be prepared
    D:be wrecked

    答案:D
    解析:

    What Makes Me the Weight I Am?
    There's no easy answer to this question.Your genetic makeup,the physical traits that get passed down to you from your parents,plays a big part in determining your size and weight. ______(46)But if your parents are smaller than average,you may want to rethink that professional basketball career!
    The same goes for your body type.Have you ever heard someone say a person is"big boned"?It's a way of saying the person has a large frame,or skeleton.Big bones usually weigh more than small bones. ______(47) Like your height or body type,your genes have a lot to say about what your weight will be.But that's only part of the story.Being overweight can run in someone 's family , but it may not be because of their genes._______ (48 ) And even though some kids gain weight more easily than others , when they eat right and exercise , most kids can be a healthy and happy weight that's right for them.It's true the way you live can change the way you look.
    How much you weigh is a balance between the calories you eat and the calories you use. ______(49)If you spend your free time watching TV, your body won' t use as many calories as it would if you played basketball,skated,or went for a walk.If you are in balance,your weight will stay right for you as you grow.But if you eat more and exercise less,you may become overweight.______(50)

    ______(50)
    A:That's why it's possible for two kids with the same height but different weight,to both be the right weight.
    B:If you eat more calories than your body needs to use,you will gain too much weight.
    C:Poor eating and exercise habits also run in families and this may be the reason the members.of a family are overweight.
    D:However , many overweight people have difficulty reaching their healthy body weight.
    E:On the other hand, "you eat less and exercise more, you, may lose weight.
    F:If both your parents are tall,there is a good chance you'II be tall.

    答案:E
    解析:
    空格前后句中都出现了parents,因此判断空格处也谈及parents的可能性很大,因此首先注意F项。而且空格前句中的your size and weight呼应F项中的tall,而空格后句中的smal-ler也是在说身高的问题,因此判断F是答案。
    由此空前文内容可知,人的骨骼有大小之分,而大骨架通常比小骨架要重,因此才有可能出现这种现象,即身高相同、体重不同的两个孩子体重均正常。
    前一句讲,身体超重有可能在家族中代代相传,但又不一定是基因遗传所致,接下来的句子就应说明其原因,即不良的饮食与运动习惯也代代相传,而这可能正是家族成员普遍超重的原因。
    空格前后句中都出现了“calories(热量)”,因此判断空格处出现该词的可能性较大,因此首先重点注意B项。空格后面的句子结构是“if you… , your body…”,该结构也正好与B呼应,形成排比结构,因此判断B是答案。
    前一句表明,如果一个人吃得多而运动得少,就有可能超重。“反之亦然”,即“吃得少而运动得多,体重就会减轻”,这显然应该是下一句要表达的意思。

    There is no creature that does not need sleep or complete rest every day.
    If you want to know why,just try going without sleep for a long period of time.You will discover that your mind and body would become too tired to work properly.You would become irritable and find it hard to think clearly or concentrate on your work.So sleep is quite simply the time when the ceils of?your body recover from the work of the day and build up supplies of energy for the next period of activity.
    One of the things we all know about sleep is that we are Unconscious in sleep,We do not know what is going on around us.But that do.esn′t mean the body stops all activity.The important organs continue to work during sleep,but most of the body functions are slowed down.
    For example,our breathing becomes slower and deeper.The heart beats more slowly,and the blood pressure is lower.Our arms and legs become limp(柔软的)and muscles are at rest.It would be impossible for our body to relax to such an extent if we were awake.So sleep does for us what the?most quiet rest can not do.
    Your body temperature becomes lower when you are asleep,which is the reason people go to sleep under some kind of covers.And even though you are unconscious,many of your reflexes(反射动作)still work.For instance,if someone tickles(使觉得痒)your foot,you will put it away in your sleep,or even brush a fly from your forehead.You do these things without knowing it.

    The cells of your body develop supplies of energy__________

    A.when you are asleep
    B.when you recover from your work of the day
    C.in the next period of activity
    D.when you are quiet

    答案:A
    解析:
    【考情点拨】事实细节题。【应试指导】文章第二段最后一句指出,睡眠时是身体的细胞从整天的忙碌中恢复并为下一个阶段的活动增加能量供应的时间。故选A。

    How the Body Keeps the Same Temperature

    The temperature of your body should always be the same if you are fine,no matter whether the weather
    is hot or cold.That is why the doctor tests your temperature with a thermometer when you are sick.Normally,
    your body teniperature is ninety-eight point six degrees Fahrenheit.If it is_______(51)than that,it is a
    stire sign that something is wrong with your body.
    Your body keeps the same temperature all the time,because it balances the heat it produces and the

    this works.
    The heat of your body is given off chiefly through the skin.When you feel_______(54),your skin
    is tight and shows"goose flesh".When you feel chilly,you must_______(55)around to keep warm.
    _______(56)your muscles begin to work,bum up fuel and produce more heat.It is not_______(57)to

    _________(61)
    A:weather
    B:climate
    C:circumstance
    D:environment

    答案:A
    解析:
    前面的内容讲的是,体温要保持一定的稳定性,人的身体才会健康。由此可推断,体温过高或过低都说明人的身体出现了问题。结合选项可知选D。
    give off意为“发出,放出(气味、热等)";put off意为“推迟”;show off意为“炫耀”;keep off意为“使……远离”。结合句意应选A。
    前面简单提到我们的身体需要热量的时候就能产生热量,我们的身体变得太暖和的时 候就会很快地释放热量。根据上下文可知,这里是一个过渡的句子,意为“让我们看看这是怎 么工作的”。故选A。
    结合常识可知,当你感到冷的时候,会起鸡皮疙瘩。因此选D。
    make做;eat吃;work工作;jump跳。这里说的是如果你感到很冷,你必须要跳来跳去 来取暖。故选D。
    前面提到跳来跳去来取暖,那么接着肌肉就开始工作了。then表示“接着”,符合句意。
    结合常识可知,颤抖是不令人愉快的,且后面的句子中有prefer,因此应选B。
    put on意为“穿上”,符合句意。
    supply with意为“提供……”,为固定搭配,符合句意。
    more更多的;enough足够的;many很多little很少。此句意为:更多的身体热量用来蒸 发身体里的水分。因此选A。
    weather天气;climate气候;circumstance条件,状况;environment环境。结合句意应 选A。
    or否则;so that以便;but但是;and和。结合句意应选B。
    本句的意思是:你喜欢少运动是因为你的身体足够的暖和。因此选C。
    根据后面讲的夏天和冬天的感受可知,这里应选feel,
    结合上下文的意思可知,夏天人们喜欢躺在床上什么也不做,而在冬天人们通过运动 来取暖。由此可知,在冬天人们显得生机勃勃。

    第二篇

    Bone Marrow Transplantation

    Bone marrow is the spongy tissue inside some of your bones,such as your hip and thigh bones. It contains immature cells,called stem cells.The stem cells can develop into the red blood cells that carry oxygen through your body,the white blood cells that fight infections,and the platelets that help with blood clotting.
    If there is a problem with your bone marrow,a transplant can give you healthy new marrow. You could need a transplant because of a disease,such as bone marrow diseases or cancers like leukemia kemia or lymphoma.Or you might need one if a strong cancer treatment kills your healthy blood cells.
    People with cancer sometimes donate bone marrow before treatment to be transplanted later. But often the new marrow comes from a donor,either a close family member or someone unrelated.
    The healthy cells for a transplant can come from three sources:bone marrow;peripheral (circulating) blood that has an increased number of healthy blood-forming cells(also called peripheral blood stem cells or PBSC);umbilical cord blood that is collected after a baby is born.
    If you need an allogeneic transplant,your doctor will look for a marrow donor or cord blood unit that matches your HLA tissue type.HLA stands for human leukocyte antigen,a markei your immune system uses to recognize which cells belong in your body and which do not.
    Before your body can receive the healthy cells,the diseased cells must be destroyed.This is done using chemotherapy and sometimes radiation. The destruction of diseased cells is called a preparative regimen or a conditioning regimen.
    On the day of transplant,the cells from the marrow donor or cord blood unit are infused intravenously(go into your body through a large vein).These healthy cells move into the spaces inside your bones where they create new marrow. They grow and make healthy new red blood cells,white blood cells,and platelets.

    Healthy stem cells may come from the following sources EXCEPT__________.
    A:peripheral blood stem cells
    B:baby blood
    C:bone marrow
    D:cord blood

    答案:B
    解析:
    细节题。第三段最后一句:通常新骨髓来源于一个捐献者,或者是血缘亲近的家人,或者是无血缘关系的陌生人。B不全面,C“器官捐献者”,也不正确。
    词义推断题。第一段第二句:它包括不成熟的细胞,被称作干细胞。A是 “主要的”,B是“杰出的”,D是“重要的”,只有C是“发育不完全的”。
    细节题。由第四段可以看出,A、C、D都是文章提到的,只有B"婴儿的血液”除外。
    细节题。倒数第二段提到了生病的细胞一定要被破坏掉,A和B都是破坏的方式,都不全面。C意思不明,且与文义不符。D的意思是被彻底破坏掉。
    推断题。A选项文章没有提及。C选项语气过于绝对,文章中没有如此说明。第三段第一句说癌症患者有时会在治疗前捐出骨髓用于日后的移植,D选项说必须,则是不正确的。从文章中可以看出,骨髓移植是很复杂的,因此B选项是可以推断出来的。
