Sleep
Sleep is part of a person's daily activity cycle .There are several different stages of sleep,and they too occur in cycles.______(46)
When you first drift off into slumber,your eyes will roll about a bit,your temperature will drop slightly,your muscles will relax,and your breathing will slow and become quite regular. Your brain waves slow down a bit too,with the alpha rhythm of rather fast waves predominating for the first few minutes.______(47)
For the next half hour or so,as you relax more and more,you will drift down through stage 2 and stage 3 sleep.______(48)
Then about 40 to 60 minutes after you lose consciousness you will have reached the deepest sleep of all.Your brain waves will show the large slow waves that are known as the delta rhythm.
This is stage 4 sleep.You do not remain at this deep fourth stage all night long,but instead about 80 minutes after you fall into slumber,your brain activity level will increase again slightly. ______(49)
Your eyes will begin to dart around under your closed eyelids as if you were loo-king at something occurring in front of you.______(50)
It is during REM sleep period,your body will soon relax again,your breathing will grow slow and regular once more,and you will slip gently back from stage 1 to stage 4 sleep-only to rise once again to the surface of near consciousness some 80 minutes later.

______(46)
A: The delta rhythm will disappear,to be replaced by the activity pattern of brain waves.
B: If you are an average sleeper,your sleep cycle is as follows.
C: In stage 4 sleep people tend to dream.
D: The lower your stage of sleep,the slower your brain waves will be.
E: This period of rapid eye movement lasts for some 8 to 15 minutes and is called REM sleep.
F: This is called stage 1 sleep.

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'5right for them.It's true一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)

__________(46)
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 areoverweight.
D:However,many overweight people have difficulty reaching their healthy body weight.
E:On the other hand,if you eat less and exercise more,you may lose weight.
F:If both your parents are tall,there is a good chance you'11 be tall.

答案：F

解析：

从文章内容我们注意到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。而且空格前句中的your size and weight呼应F中的tall，而空格后句中的smaller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。也是讲述身高和体重的关系。
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，即不良的饮食习惯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。
我们注意到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,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所表达的意思。第6部分：完形填空

Energy Cycle

Do you find getting up in the morning so difficult that it's painful?This might be called laziness, but Dr. Kleitman has a new explanation.He has proved that everyone has a daily energy cycle.
During the hours when you labor through your work you may say that you are"hot".That's true.The time of day when you feel most energetic is when your cycle of body temperature is at this peak.For some people the peak comes during the morning. For others it comes in the afternoon or evening. No one has discovered why this is so,but it leads to such familiar words as:"Get up, John!You'll be late for work again!"The possible explanation to the trouble is he is at his tempera-ture-and-energy peak in the evening. Much family quarrelling ends when husbands and wives realize what these energy cycles mean,and which cycle each member of the family has.
You can't change your energy cycle,but you can learn to make your life fit it better. Habit can help,Dr. Kleitman believes.Maybe you're sleepy in the evening but feel you must stay up late anyway.Counteract your cycle to some extent by habitually staying up later than you want to.If your energy is low in the morning but you have an important job to do early in the day,rise before your usual hour. This won't change your cycle,but you'll get up steam and work better at your low point.
Get off to a slow start,which saves your energy.Get up with a leisurely yawn and stretch.Sit on the edge of the bed a minute before putting your feet on the floor. Avoid the troublesome search for clean clothes by laying them out the night before.Whenever possible,do routine work in the afternoon and save tasks requiring more energy for your sharper hours.

Energy cycle may be inherited from your parents.
A:Right
B:Wrong
C:Not mentioned

答案：C

解析：

虽然文章第一段提到早上起不来床会被称为懒，但是本文强调的是Kleitman博士所提出的新观点，就是这可能是由于每个人不同的能量周期决定的。因此不是所有早上起不来的人都是懒，所以这句话是错误的。
根据文章第二段和第三段我们知道能量峰值在晚上的人早上精神会不好，能量峰值在早上的人则相反，因此本句是正确的。
文章第二段最后一句讲到如果夫妻双方都能意识到能量周期的不同，那么“much family quarrelling ends”，即少了许多争吵，也就是说很多争吵是因为没有意识到能量周期的问题，因此本句表述是错误的。
第二段三句讲“The time of day when you feel most energetic is when your cycle of body temperature is at this peak"，即精力最充沛的时候体温最高，但这并不意味着精力和体温是一码事，例如人生病的时候会发烧但精神会很差。本句的表述是错误的。
文章第二段告诉我们“No one has discovered why this is so”，即没人知道为什么每个人的能量周期不同，因此我们也不知道是不是有遗传因素，所以选择选项C。
第三段第一句告诉我们虽然可以让自己的生活适应能量周期，但是“you can't change your energy cycle"，因此本句表述是错误的，应当选择选项B。
文章第三段最后两句建议早上处于低潮的人们要比平时起得早，这样才能工作得更好。因此本句的陈述是正确的。

Did you sleep well last night? Maybe many people will answer No.In fact, in the world about one in three people do not have good sleep.(1) you say you do not have good sleep, it means waking early and not getting back to sleep, of ten interrupted short period of sleep, or hours or wakefulness.You (2) get tired, worried, and anxious.Your menory and ability to remember things will be affected

Parkinson's Disease

1 Parkinson's disease affects the way you move.It happens when there is a problem with certain nerve
cells in the brain. Normally , these nerve cells make an important chemical called dopamine（多巴胺）. Dopa-
mine sends signals to the part of your brain that controls movement.It lets your muscles move smoothly and
do what you want them to do.When you have Parkinson's,these nerve cells break down.Then you no longer
have enough dopamine,and you have trouble moving the way you want to.
2 No one knows for sure what makes these nerve cells break down.But scientists are doing a lot of re-
search to look for the answer. They are studying many possible causes,including aging and poisons in the en-
vironment.Abnormal genes seem to lead to Parkinson's disease in some people.But so far,there is not enough
proof to show that it is always inherited.
3 Tremor（颤抖）may be the first symptom you notice.It is one of the most common signs of the
disease,although not everyone has it.Tremor often starts in just one arm or leg or only on one side of the
body.It may be worse when you are awake but not moving the affected arm or leg. It may get better when you
move the limb or when you are asleep.In time,Parkinson's affects muscles all through your body,so it can
lead to problems like trouble swallowing or constipation（便秘）.In the later stages of the disease , a person
with Parkinson's may have a fixed or blank expression,trouble speaking,and other problems.Some people
also have a decrease in mental skills.
4 At this time,there is no cure for Parkinson's disease.But there are several types of medicines that
can control the symptoms and make the disease easier to live with.You may not even need treatment if your
symptoms are mild.Your doctor may wait to prescribe medicines until your symptoms start to get in the way of
your daily life.Your doctor will adjust your medicines as your symptoms get worse.You may need to take
several medicines to get the best results.

Paragraph 1__________
A:Means of Diagnosis of the Disease
B:Tips for Patients With the Disease
C:Common Treatment for the Disease
D:Definition of Parkinson's Disease
E:Possible Causes of the Disease
F: Typical Symptoms of the Disease

答案：D

解析：

即帕金森综合征的定义。本段的中心意思是什么是帕金森综合征。
即导致疾病产生的可能的原因。本段主要探讨的是这种疾病发生的原因。
即疾病的典型症状。本段讲的是帕金森综合征的一些典型的病症，如颤抖、吞咽困难和便秘等等。
即通常的治疗方法。从本段可知，虽然帕金森综合征还不能治愈，但是可以通过几种药物控制患者的病症。
即如果没有足够的多巴胺你会发现自己难以随心所欲地行动。根据第一段最后一句 "Then you no longer have enough dopamine,and you have trouble moving the way you want to.”可知，本题应选B。
即科学家做了很多研究试图发现导致帕金森综合征的原因。从第二段第一句“No one knows for sure what makes these nerve cells break down.”可知，本题应选F。
即帕金森病最常见的病症是颤抖，它可能是你发现的第一个症状。从第三段第一句 " Tremor (颤抖）may be the first symptom you notice.”可知，本题应选D。
患帕金森综合征的人必须学会带着这种病生活，因为现在人们还无法治愈它，从最后一段第一句“At this time , there is no cure for Parkinson's disease.”可知，本题应选C。

第6题：

______(48)
A: The delta rhythm will disappear,to be replaced by the activity pattern of brain waves.
B: If you are an average sleeper,your sleep cycle is as follows.
C: In stage 4 sleep people tend to dream.
D: The lower your stage of sleep,the slower your brain waves will be.
E: This period of rapid eye movement lasts for some 8 to 15 minutes and is called REM sleep.
F: This is called stage 1 sleep.

答案：D

解析：

如果你是一个正常的睡眠者，你的睡眠循环会这样进行。本文以一个人的睡眠过程为例，说明睡眠的不同阶段和周期。从接下来的文章中看出以下就是描述睡眠的四个阶段和周期，因此这里选择B导入这个叙述。

这被称为第一阶段睡眠。根据接下来一句话：在随后约半小时内，你进一步放松，进入第二和第三阶段睡眠，可以推断该句之前描述的就是睡眠的第一阶段。

睡眠越深入，脑电波就越缓慢。接下来两句话说：大约在开始睡眠后的40～6O分钟，你将进入沉睡状态。这时脑电波表现为巨大的缓波，被称为δ节律。可以看出沉睡和脑电波的缓波为正比发生的，因此选D。

δ节律消失，并被脑电波的运动图形取代。该句前一句说：入睡后约80分钟左右，你的大脑运动水平会再度略有提高。δ节律被再次运动的脑电波图形取代，因此选A。

这种迅速的眼球运动持续约8～15分钟，这一阶段睡眠被称之为快速眼动（REM)睡眠。接下来一句说：在REM睡眠阶段，你的肢体会很快再度放松，呼吸也再次放慢并变得有节奏，你会轻松地从第一阶段滑入第四阶段睡眠——直到大约80分钟后重新接近清醒状态。这里的REM和前一句相衔接。

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：F

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。
