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。

Smart Exercise

Doctors are starting to find more and more information that suggests a connection
between exercise and brain development.Judy Cameron,a scientist at Oregon Health and
Science University,studies brain development.According to her research,it seems that
exercise can make blood vessels,including those in the brain,stronger and more fully
developed.Dr. Cameron claims this allows people who exercise to concentrate better. As
she says:"While we already know that exercise is good for the heart,exercise can literally
cause physical changes in the brain."
The effects of exercise on brain development can even be seen in babies.Babies who
do activities that require a lot of movement and physical activity show greater brain
development than babies who are less physically active.With babies,even a{ittle
movement can show big results. Margaret Barnes , a pediatrician（儿科医师）,believes in
the importance of exercise.She thinks that many learning disabilities that children have in
elementary school or high school can be traced back to a lack of movement as babies.
"Babies need movement that stimulates their five senses.They need to establish a
connection between motion and memory.In this way,as they get older,children will begin
to associate physical activity with higher learning,"says Margaret.
Older people can beef up their brains as well.Cornell University studied a group of
seniors ranging in age from seventy to seventy-nine. Their study showed a short-term
memory increase of up to 40 percent after exercising just three hours a week.The exercise
does not have to be very difficult,but it does have to increase the heart rate.Also,just like
the motion for infants,exercise for older people should involve some complexity.Learning
some new skills or motions helps to open up memory paths in the brain that may not have
been used for a long time.
For most people,any type of physical activity that increases the heart rate is helpful.
The main goal is to increase the brain's flow of blood.And your brain can benefit from as
little as two to three hours of exercise a week.

The expression"beef up"in paragraph 3 means
A:control.
B: strengthen.
C:operate.
D: encourage.

答案：B

Napping to a Healthier Heart?
1 Researchers say they have developed a simple test that can tell if a person with heart disease is likely to suffer a heart attack.The test measures levels of a protein in the blood.The researchers say people with high levels of this protein are at high risk of heart attack,heart failure or stroke.
2 Kirsten Bibbins-Domingo of the University of California in San Francisco led the team.For about four years,they studied almost one thousand patients with heart disease.The researchers tested the heart disease patients for a protein called NT-proBNP.Patients with the highest levels were nearly eight times more likely than those with the lowest levels to have a heart attack,heart failure or stroke.
3 The researchers say the presence of high levels of the protein in the blood shows that the heart muscle is under pressure in some way.The study involved mostly men,so the researchers could not say for sure that the results are also true for women.They say the patients with the highest levels of NT-proBNP were older and had other problems like diabetes or high blood pressure.
4 Other researchers say more studies are needed to confirm if knowing the protein levels of a heart disease patient should affect that person's treatment.They also would like to know if more aggressive treatment could reduce the patient's chance of a heart attack or stroke.The study appeared in the Journal of the American Medical Association.
5 Could a little sleep during the middle of the day reduce the risk of a heart attack?An unrelated study earlier this month in the Archives of Internal Medicine suggests that the answer may be yes.In countries like the United States,afternoon naps are mostly for children.But they are common for adults in Mediterranean countries.And these countries generally have lower rates of heart disease.So scientists in the United States and Greece wondered if naps could play a part.Twenty-three thousand healthy adults took part in the study by Harvard University and the University of Athens.Those who took thirty-minute naps three times a week had a thirty-seven percent lower risk of death from heart problems than people who did not take naps.
6 The researchers say napping may improve heart health by reducing stress.They say the research suggests that naps are especially good for working men.But they say not enough female subjects died during the study to judge the benefits for women.

People who take regular afternoon naps______.
A:where fewer people die from heart problem
B:whether they have the risk of heart attack,heart failure or stroke
C:would probably have lower rates of heart disease
D:how to test a person's NT-proBNP level in the blood by himself
E:his heart muscle would be under pressure in some way
F:that napping is of great benefit to women too

答案：C

解析：

第二段主要介绍了加利福尼亚大学一个团队所进行的研究。通过检查心脏病人的NT-proBNP水平，发现水平最高的病人与水平最低的病人之间患心脏病的可能性相差近8倍。
第三段说到，研究涉及的多是男性，并发现年老且患有糖尿病或高血压者NT-proBNP的水平最高。
由第四段的内容可知，其他研究者认为还要确认一些问题，如心脏病病人的蛋白质水平是否影响其治疗；他们还想知道更多的积极治疗能否减少病人得心脏病或中风的机会。
第五段说到，地中海国家的成年人普遍都午睡，而且患心脏病的几率较低。哈佛大学和雅典大学的研究证明，每周午睡三次，每次30分钟的人比完全不午睡的人死于心脏病的几率低37%。
由第一段最后两句可知，研究人员检测血液中蛋白质的水平，他们称血液中这种蛋白质水平高的人得心脏病或中风的几率高，故选B。
由第三段第一句可知，血液中含有高浓度的该种蛋白质证明心肌受到了压迫。
由文章第五段的内容可知，定期午睡的人患心脏病的几率更低。
由第三段第二句和文章的最后一句可知，研究对象多为男性，并且由于在调查期间女性研究对象死亡的并不多，所以无法判断午睡对女性的影响。

第6题：

Science can't explain the power of pets, but many studies have shown that the company of pets can help lower blood pressure (血压) and raise chances of recovering from a heart attack, reduce loneliness and spread all-round good cheer. Any owner will tall you how much joy a pet brings. For some, an animal provides more comfort than a husband/wife. A 2002 study by Karen Allen of the State University of New York measured stress (紧张) levels and blood pressure in people - half of them pet owners –while they performed 5 minutes of mental arithmetic (算术) or held a hand in ice water. Subjects completed the tasks alone, with a husband/wife, a close friend or with a pet. People with pets did it best. Those tested with their ani mal friends had smaller change in blood pressure and returned most quickly to baseline heart rates. With pets in the room, people also made fewer math mistakes than when doing in front of other companions. It seems people feel more relaxed (放松)around pets, says Allen, who thinks it may be because pets don't judge. A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits. Researchers at Northwestern Memorial Hospital spent a year studying 36 fat people and their equally fat dogs on diet-and-exercise programs; a separate group of 56 people without pets were put on a diet program. On average, people lost about I1 pounds, or 5% of their body weight. Their dogs did even better, losing an average of 12 pounds, more than 15% of their body weight. Dog owners didn't lose any more weight than those without dogs but, say researchers, got more exercise overall-mostly with their dogs - and found it worth doing.

67．What does the text mainly discuss?

A．What pets bring to their owners.

B．How pets help people calm down.

C．People's opinions of keeping pets.

Obesity:the Scourge of the Western World
Obesity is rapidly becoming a new scourge of the western world,delegates agreed at the 11th European Conference on the issue in Vienna Wednesday to Saturday. According to state-ments before the opening of the conference一of 2,000 specialists from more than 50 countries一1.2 billion people worldwide are overweight,and 250 million are obese.
Professor Bernhard Ludvik of Vienna General Hospital said:“Obesity is a chronic ill-ness.In Germany,20 percent of the people are already affected,but in Japan only one per-cent.”But he said that there was hope for sufferers thanks to the new scientific discoveries and medication.
Professor Friedrich Hopichler of Salzberg said:“We are living in the new age(but)with the metabolism of a stone-age man.”“I have just been to the United States.It is really terni-ble.A pizza shop is springing up on every corner. We have been overrun by fast food and Co-ca-Cola-ization.”
Many of the experts stressed that obesity was a potential killer. Hopichler said:“Eighty percent of all diabetics are obese,also fifty percent of all patients with high blood pressure and fifty percent with adipose tissue complaints.”“Ten percent more weight means thirteen percent more risk of heart disease.Reducing one's weight by ten percent leads to thirteen percent lower blood pressure.”
Another expert Hermann Toplak said that the state health services should improve their financing of preventive programs.“Though the health insurance pays for surgery( such as re-ducing the size of the stomach)when the body-mass index is more than 40.That is equivalent to a weight of 116 kilograms for a height of 1.70 meters.One should start earlier.”
Ludvik said that prevention should begin in school.“Child obesity(fat deposits)correlates with the time which children spend in front of TV sets.”The consequences were only apparent later on. No more than fifteen percent of obese people lived to the average life ex-pectancy for their population group.

What is the correlation between body weight and heart disease and blood pressure?
A: Ten percent less body weight means ten percent less risk of heart disease and high blood pressure.
B: Thirteen percent more body weight means ten percent more risk of heart disease and high blood pressure.
C: The more body weight one gains,the more risk of heart disease and high blood pressure he has.
D: The less body weight one gains,the more risk of heart disease and the less risk of high blood pressure he has.

答案：C

解析：

题干意为“据估计，全世界有……人患有肥胖病”。备选项很特殊，全是数字，因此利用备选项中的数字作为定位线索，在第一段找到相关句：Obesity is rapidly becoming a new scourge of the western world,delegates agreed at the 11th European Conference on the issue in Vienna Wednesday to Saturday. According to statements before the opening of the conference一of 2,000 specialists from more than 50 countries一1.2 billion people worldwide are overweight , and 250 million are obese．相关句（定位线索词集中出现的句子）提到“全世界有12亿人体重超重，而2.5亿人肥胖”。由此判断答案为A。
题干意为“短文中提到在发达国家中……的居民可能受到肥胖的影响最小”。利用题干及备选项中的细节信息词/短语developed countries and areas , European, German,American, Japanese作为定位线索，同时关注题干中的修饰词least affected（受到影响最小的），在第二段中找到相关句：Professor Bernhard Ludvik of Vienna General Hospital said: “Obesity is a chronic illness. In Germany（与Germany呼应）,20 percent of the people are already affected , but in Japan（与Japanese呼应）only one percent. ”But he said that there was hope for sufferers thanks to the new scientific discoveries and medication．相关句提到“德国20%的人已经患有肥胖病，而日本只有1%”。在第三段中作者说他去过美国，那里到处是比萨店，快餐食品，可口可乐，可见美国的胖人也不少。至于全欧洲，因为这次关于肥胖问题的会议是在维也纳召开的，而且短文第一句提到肥胖症正迅速成为西方世界的祸害，由此可推断出欧洲胖人也不少，因此发达国家中受到肥胖症影响的最小的可能就是日本了。所以答案为D。
题干意为“下面哪种疾病最常伴随肥胖病出现？”关注题干中的修饰词most often，利用备选项中的细节信息词/短语high blood pressure, fatty tissue complaints, diabetes, stomach-ache作为定位线索，在第四段中找到相关句：Many of the experts stressed that obesity was a potential killer. Hopichier said:“Eighty percent of all diabetics（与diabetes呼应）are obese,also fifty percent of all patients with high blood pressure and fifty percent with adipose tissue complaints.”“Ten percent more weight means thirteen percent more risk of heart disease. Reducing one's weight by ten percent leads to thirteen percent lower blood pressure.”相关句提到“80%的糖尿病患者肥胖，而高血压和脂肪组织疾病患者伴有肥胖症的都各为50%”，由此可见糖尿病并发肥胖病是最多的，所以答案为C。
题干意为“体重，心脏病和血压之间有什么关系？”利用题干中的细节信息词/短语correlation, body weight , heart disease, blood pressure作为定位线索，在第四段找到相关句：Many of the experts stressed that obesity was a potential killer. Hopichier said:“Eighty percent of all diabetics are obese,also fifty percent of all patients with high blood pressure and fifty percent with adipose tissue complaints.”“Ten percent more weight means thirteen percent more risk of heart disease. Reducing one's weight by ten percent leads to thirteen percent lower blood pressure.”相关句提到“体重增加10%意味着患心脏病的危险性增加13%，体重减少10%可导致血压降低13%”，由此可判断答案为C项“体重越重，患心脏病和高血压的风险越大”。

Passage Four

After a busy day of work and play, the body needs to rest. Sleep is necessary for good health. During this time, the body recovers from the activities of the previous day. The rest that you get while sleeping enables your body to prepare itself for the next day.

There are four levels of sleep, each being a little deeper than the one before. As you sleep, your muscles relax little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts back and forth from one level of sleep to the other.

Although your mind slows down, from time to time you will dream. Scientists who study sleep state that when dreaming occurs, your eyeballs begin to move more quickly (although your eyelids are closed). This stage of sleep is called REM, which stands for rapid eye movement.

If you have trouble falling asleep, some people recommend breathing very slowly and very deeply. Other people believe that drinking warm milk will help make you drowsy. There is also an old suggestion that counting sheep will put you to sleep!

46. A good title for this passage is ______.

A. Sleep

B. Good Health

C. Dreams

D. Work and Rest

正确答案：A
