参考答案和解析
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。

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.You'll find it hard to move the way you want to__________.
A:what affects muscles all through your body
B:if there isn't enough dopamine in your body
C:which cannot be cured yet
D:which may be the first symptom you notice
E:if you have a fixed or blank expression
F: what causes Parkinson's disease答案：B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。 -

The Best Way to Reduce Your Weight
You hear this:"No wonder you are fat.All you ever do is eat."You feel sad:"I skip my breakfast and
supper. I run every morning and evening. What else can I do?"Basically you can do nothing. Your genes,not
your life habits,determine your weight and your body constantly tries to maintain it.
Albert Stunkard of the University of Pennsylvania found from experiments that"80 percent of the chil-
dren of two obese（肥胖的）parents become obese , as compared with no more than 14 percent of the offspring
of two parents of normal weight."
How can obese people become normal or even thin through dieting? Well,dieting can be effective,but
the health costs are tremendous.Jules Hirsch,a research physician at Rockefeller University,did a study of
eight fat people.They were given a liquid formula providing 600 calories a day.After more than 10 weeks,the
subjects lost 45kg on average.But after leaving the hospital,they all regained weight. The results were sur-
prising : by metabolic（新陈代谢的）measurement , fat people who lost large amounts of weight seemed like
they were starving. They had psychiatric problems.They dreamed of food or breaking their diet. They were
anxious and depressed;some were suicidal.They hid food in their rooms.Researchers warn that it is possible
that weight reduction doesn't result in normal weight,but in an abnormal state resembling that of starved
nonobese people.
Thin people,however,suffer from the opposite:They have to make a great effort to gain weight.Ethan
Sims,of the University of Vermont,got prisoners to volunteer to gain weight. In four to six months,they ate as
much as they could. They succeeded in increasing their weight by 20 to 25 percent.But months after the
study ended,they were back to normal weight and stayed there.
This does not mean that people are completely without hope in controlling their weight.It means that
those who tend to be fat will have to constantly battle their genetic inheritance if they want to significantly
lower their weight. The findings also provide evidence for something scientists thought was true一each person
has a comfortable weight range.The range might be as much as 9kg. Someone might weigh 60～69kg without
too much effort. But going above or below the natural weight range is difficult. The body resists by feeling
hungry or full and changing the metabolism to push the weight back to the range it seeks.In Ethan Sims'study,the subjects were asked to________.
A:stay in prison
B:eat as much as they could
C:battle their genetic inheritance
D:lower their weight答案：B解析：短文第一段的后面一句话提到，是你的基因而不是你的生活习惯决定了你的体重，而 且你的身体其实一直在努力维持着你的体重，由此可知是你的基因决定你的体重。
短文第三段中说到，研究人员给参加实验的八位肥胖人士每天提供只含600卡路里的流质食物。
短文第三段中说到，“但是在他们离开医院以后，他们的体重又恢复了”，可以看出他们的体重最终又恢复到了原来的状态，所以选B。
短文第四段讲研究人员如何让瘦人增加体重。Ethan Sims从犯人中招募志愿者，让他 们增加体重的办法就是让他们吃尽可能多的食物。
短文最后一段说到，科学家们的发现证明了他们的想法，即每个人都有一个适合自己 的体重范围，这个幅度可能是9公斤，但并非每个人都是同样的幅度，所以可以否定干扰项B。 -

It is natural for young people to be critical of their parents at times and to blame them for most of the misunderstandings between them.They have always complained,more or less justly,that their parents are out of touch with modern ways;that they are possessive and dominant;that they do not trust their children to deal with crisis;that they talk too much about certain problems;and that they have no sense of humor,at least in parent-hild relationships.
I think it is true that parents often underestimate their teenage children and also forget how they themselves felt when young.
Young people often irritate their parents with their choices in clothes and hairstyles,in entertainments and music.This is not their motive.They feel cut off from the adult world into which they have not yet been accepted.So they create a culture and society of their own.Then,if it turns out that their music or entertainments or vocabulary or clothes or hairstyles irritate their parents,this gives them additional enjoyment. They feel they are superior,at least in a small way,and that they are leaders in style and taste.
Sometimes you are resistant and proud because you do not want your parents to approve of what you do.If they did approve,it looks as if you are betraying your own age group.But in that case, you are assuming that you are the underdog:you can't win but at least you can keep your honor. This is a passive way of looking at things.It is natural enough after long years of childhood,when you were completely under your parents' control. But it ig而res the fact that you are now beginning to be responsible for yourself.
If you plan to control your life,cooperation can be part of that plan.You can charm others,especially your parents,into doing things the way you want.You can impress others with your sense of responsibility and initiative,so that they will give you the authority to do what you want to do.Teenagers tend to have strange clothes and hairstyles because they__________.
A:have strong desire to be leaders in style and taste
B:want to show their existence by creating a culture of their own
C:have no other way to enjoy themselves in a better way
D:want to be annoyed with parents答案：A解析：推断题。本文前三段作者站在青少年的角度对于青少年和父母之间存在的一些问题表示深深的理解，后两段则是用直接对青少年说话的口气，文中出现很多以青少年为主语的you，例如：Sometimes you are resistant and proud because you do not want your parents to approve of what you do…you are betraying your own age group…，you are assuming that you are the underdog : you can't win but at least you can keep your honor．因此本文的目标读者就是十几岁的青少年。
推断题。第一段中提及：It is natural for young people to be critical of their parents at times and to blame them for most of the misunderstandings between them.They have always complained，其中be critical of , blame , complain这些都是关键词，由此可知第一段主要是讲青少年对父母的批评。
推断题。第三段最后一句：They feel they are superior , at least in a small way , and that they are leaders in style and taste．他们感觉自己高人一等，至少在一些次要的方面，而且感觉自己引领时尚和品位。由此可知，青少年之所以奇装异服，就是因为想引领时尚。
推断题。第四段中提到：Sometimes you are resistant and proud because you do not want your parents to approve of what you do…It is natural enough after long years of childhood , when you were completely under your parents' control．有时候你很叛逆和骄傲就是因为你不想让父母对你的行为表示赞成。······经过漫长的完全处于父母控制之下的童年时代之后，这么想也很自然。孩子们想要做些父母不赞成的事情的原因就是他们受够了漫长的童年时期受父母摆布的生活，想更加独立。因此正确答案选D。
最后一段提到：If you plan to control your life,cooperation can be part of that plan．如果你计划控制自己的生活，合作将会是这个计划的一部分。由此可知作者建议青少年要学会合作。因此正确答案选C。 -

How can obese people become normal or even thin through dieting?Well,dieting can be effective,but the health costs are tremendous.Jules Hirsch,a research physician at Rockefeller University,did a study of eight fat people.They were given a liquid formula providing 600 calories a day.After more than 10 weeks,the subjects lost 45kg on average.But after leaving the hospital,they all regained weight. The results were surprising:by metabolic measurement,fat people who lost large amounts of weight seemed like they were starving. They had psychiatric problems.They dreamed of food or breaking their diet.They were anxious and depressed;some were suicidal. They hid food in their rooms.Researchers warn that it is possible that weight reduction doesn't result in normal weight,but in an abnormal state resembling that of starved non-obese people.
Thin people,however,suffer from the opposite:They have to make a great effort to gain weight. Ethan Sims,of the University of Vermont,got prisoners to volunteer to gain weight. In four to six months,they ate as much as they could.They succeeded in increasing their weight by 20 to 25 percent. But months after the study ended,they were back to normal weight and stayed there.
This did not mean that people are completely without hope in controlling their weight. It means that those who tend to be fat will have to constantly battle their genetic inheritance if they want to significantly lower their weight.
The findings also provide evidence for something scientists thought was true一each person has a comfortable weight range. The range might be as much as 9kg. Someone might weigh 60-69kg without too much effort.But going above or below the natural weight range is difficult. The body resists by feeling hungry or full and changing the metabolism to push the weight back to the range it seeks.What did scientists think was true?
A:Each person has a fixed weight range.
B:Each person has a weight range of 9 kg.
C:Each person wants to control his weight.
D:Each person wants to eat to his heart's content.答案：A解析：题干意思：什么决定你的体重？第一段中：Your genes , not your life habits, determine your weight and your body constantly tries to maintain it．你的基因而不是你的生活习惯决定了你的体重，而且你的身体总是试图保持原样。所以选择D。
题干意思：Jules Hirsch在他的研究中做了什么？第三段中：They were given a liquid formula providing 600 calories a day．可以得出D选项正确。
题干意思：8个肥胖者出院后怎么了？ 第四段的最后一句：But months after the study ended , they were back to normal weight and stayed there．研究结束几个月后，他们的体重又回到了原来的样子，并保持不变。所以选择C项。
题干意思：Ethan Sims让他的调查对象干什么？ 第四段中：Ethan Sims,of the University of Vermont , got prisoners to volunteer to gain weight．佛蒙特州立大学的Ethan Sims 在罪犯中招募志愿者去增重。可见选项B是正确的答案。

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)__________(48)
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：C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 -

The Best Way to Reduce Your Weight
You hear this:"No wonder you are fat.All you ever do is eat."You feel sad:"I skip my breakfast and
supper. I run every morning and evening. What else can I do?"Basically you can do nothing. Your genes,not
your life habits,determine your weight and your body constantly tries to maintain it.
Albert Stunkard of the University of Pennsylvania found from experiments that"80 percent of the chil-
dren of two obese（肥胖的）parents become obese , as compared with no more than 14 percent of the offspring
of two parents of normal weight."
How can obese people become normal or even thin through dieting? Well,dieting can be effective,but
the health costs are tremendous.Jules Hirsch,a research physician at Rockefeller University,did a study of
eight fat people.They were given a liquid formula providing 600 calories a day.After more than 10 weeks,the
subjects lost 45kg on average.But after leaving the hospital,they all regained weight. The results were sur-
prising : by metabolic（新陈代谢的）measurement , fat people who lost large amounts of weight seemed like
they were starving. They had psychiatric problems.They dreamed of food or breaking their diet. They were
anxious and depressed;some were suicidal.They hid food in their rooms.Researchers warn that it is possible
that weight reduction doesn't result in normal weight,but in an abnormal state resembling that of starved
nonobese people.
Thin people,however,suffer from the opposite:They have to make a great effort to gain weight.Ethan
Sims,of the University of Vermont,got prisoners to volunteer to gain weight. In four to six months,they ate as
much as they could. They succeeded in increasing their weight by 20 to 25 percent.But months after the
study ended,they were back to normal weight and stayed there.
This does not mean that people are completely without hope in controlling their weight.It means that
those who tend to be fat will have to constantly battle their genetic inheritance if they want to significantly
lower their weight. The findings also provide evidence for something scientists thought was true一each person

too much effort. But going above or below the natural weight range is difficult. The body resists by feeling
hungry or full and changing the metabolism to push the weight back to the range it seeks.Which of the following statements is true?
A:Each person wants to eat to his heart's content.
B:Each person has a weight range of 9kg.
C:Each person has a natural weight range.
D:Each person wants to control his weight.答案：C解析：短文第一段的后面一句话提到，是你的基因而不是你的生活习惯决定了你的体重，而 且你的身体其实一直在努力维持着你的体重，由此可知是你的基因决定你的体重。
短文第三段中说到，研究人员给参加实验的八位肥胖人士每天提供只含600卡路里的流质食物。
短文第三段中说到，“但是在他们离开医院以后，他们的体重又恢复了”，可以看出他们的体重最终又恢复到了原来的状态，所以选B。
短文第四段讲研究人员如何让瘦人增加体重。Ethan Sims从犯人中招募志愿者，让他 们增加体重的办法就是让他们吃尽可能多的食物。
短文最后一段说到，科学家们的发现证明了他们的想法，即每个人都有一个适合自己 的体重范围，这个幅度可能是9公斤，但并非每个人都是同样的幅度，所以可以否定干扰项B。 -

It is natural for young people to be critical of their parents at times and to blame them for most of the misunderstandings between them.They have always complained,more or less justly,that their parents are out of touch with modern ways;that they are possessive and dominant;that they do not trust their children to deal with crisis;that they talk too much about certain problems;and that they have no sense of humor,at least in parent-hild relationships.
I think it is true that parents often underestimate their teenage children and also forget how they themselves felt when young.
Young people often irritate their parents with their choices in clothes and hairstyles,in entertainments and music.This is not their motive.They feel cut off from the adult world into which they have not yet been accepted.So they create a culture and society of their own.Then,if it turns out that their music or entertainments or vocabulary or clothes or hairstyles irritate their parents,this gives them additional enjoyment. They feel they are superior,at least in a small way,and that they are leaders in style and taste.
Sometimes you are resistant and proud because you do not want your parents to approve of what you do.If they did approve,it looks as if you are betraying your own age group.But in that case, you are assuming that you are the underdog:you can't win but at least you can keep your honor. This is a passive way of looking at things.It is natural enough after long years of childhood,when you were completely under your parents' control. But it ig而res the fact that you are now beginning to be responsible for yourself.
If you plan to control your life,cooperation can be part of that plan.You can charm others,especially your parents,into doing things the way you want.You can impress others with your sense of responsibility and initiative,so that they will give you the authority to do what you want to do.In order to improve parent-hild relationship teenagers are advised to be_________.
A:responsible
B:independent
C:cooperative
D:obedient答案：C解析：推断题。本文前三段作者站在青少年的角度对于青少年和父母之间存在的一些问题表示深深的理解，后两段则是用直接对青少年说话的口气，文中出现很多以青少年为主语的you，例如：Sometimes you are resistant and proud because you do not want your parents to approve of what you do…you are betraying your own age group…，you are assuming that you are the underdog : you can't win but at least you can keep your honor．因此本文的目标读者就是十几岁的青少年。
推断题。第一段中提及：It is natural for young people to be critical of their parents at times and to blame them for most of the misunderstandings between them.They have always complained，其中be critical of , blame , complain这些都是关键词，由此可知第一段主要是讲青少年对父母的批评。
推断题。第三段最后一句：They feel they are superior , at least in a small way , and that they are leaders in style and taste．他们感觉自己高人一等，至少在一些次要的方面，而且感觉自己引领时尚和品位。由此可知，青少年之所以奇装异服，就是因为想引领时尚。
推断题。第四段中提到：Sometimes you are resistant and proud because you do not want your parents to approve of what you do…It is natural enough after long years of childhood , when you were completely under your parents' control．有时候你很叛逆和骄傲就是因为你不想让父母对你的行为表示赞成。······经过漫长的完全处于父母控制之下的童年时代之后，这么想也很自然。孩子们想要做些父母不赞成的事情的原因就是他们受够了漫长的童年时期受父母摆布的生活，想更加独立。因此正确答案选D。
最后一段提到：If you plan to control your life,cooperation can be part of that plan．如果你计划控制自己的生活，合作将会是这个计划的一部分。由此可知作者建议青少年要学会合作。因此正确答案选C。 -
