阅读下列四篇短文，从每小题后所给的A,B,C或D四个选项中，选出最佳选项。
Below is a selection from a popular science book.
If blood is red，why are veins(静脉) blue?
Actually，veins are not blue at all.They are more of a clear，yellowish colour.Although blood looks red when it's outside the body，when it's sitting in a vein near the surface of the skin，it's more of a dark reddish purple colour.At the right depth，these bloodfilled veins reflect less red light than the surrounding skin，making them look blue by comparison.
Which works harder，your heart or your brain?
That kind of depends on whether you're busy thinking or busy exercising.Your heart works up to three times harder during exercise，and shifts enough blood over a lifetime to fill a supertanker.But，in the long run，your brain probably tips it，because even when you're sitting still your brain is using twice as much energy as your heart，and it takes four to five times as much blood to feed it.
Why do teeth fall out，and why don't they grow back in grownups?
Baby (or “milk”) teeth do not last long；they fall out to make room for bigger，stronger adult teeth later on.Adult teeth fall out when they become damaged，decayed and infected by bacteria.Once this second set of teeth has grown in，you're done.When they're gone，they're gone.This is because nature figures you're set for life，and what controls regrowth of your teeth switches off.
Do old people shrink as they age?
Yes and no.Many people do get shorter as they age.But，when they do，it isn't because they're shrinking all over.They simply lose height as their spine(脊柱) becomes shorter and more curved due to disuse and the effects of gravity(重力)．Many (but not all) men and women do lose height as they get older.Men lose an average of 34 cm in height as they age，while women may lose 5 cm or more.If you live to be 200 years old，would you keep shrinking till you were，like 60 cm tall，like a little boy again？No，because old people don't really shrink！It is not that they are growing backwards—their legs，arms and backbones getting shorter.When they do get shorter，it's because the spine has shortened a little.Or，more often，become more bent and curved.
Why does spinning make you dizzy(眩晕的)?
Because your brain gets confused between what you're seeing and what you're feeling.The brain senses that you're spinning using special gravityandmotionsensing organs in your inner ear，which work together with your eyes to keep your vision and balance stable.But，when you suddenly stop spinning the system goes out of control，and your brain thinks you're moving while you're not!
Where do feelings and emotions come from?
Mostly from an ancient part of the brain called the limbic system.All mammals have this brain area—from mice to dogs，cats，and humans.So all mammals feel basic emotions like fear，pain and pleasure.But since human feelings also involve other，newer bits of the brain，we feel more complex emotions than any other animal on the planet.
If exercise wears you out，how can it be good for you?
Because our bodies adapt to everything we do to them.And as far as your body is concerned，it's “use it，or lose it”！It's not that exercise makes you healthy；it's more that a lack of exercise leaves your body weak and easily affected by disease.
1．What is the colour of blood in a vein near the surface of the skin?A．Blue.
B．Light yellow.
C．Red.
D．Dark reddish purple.
解析 细节理解题。根据第一个标题下的“...it's more of a dark reddish purple colour.”可知答案。
答案 D2．Why do some old people look a little shrunken as they age?
A．Because their spine is in active use.
B．Because they are more easily affected by gravity.
C．Because they keep growing backwards.
D．Because their spine becomes more bent.
解析 细节理解题。根据第四个标题下的“They simply lose height as their spine(脊柱) becomes shorter and more curved due to disuse and the effects of gravity(重力)．”可知，老年人变矮是因为脊柱收缩和弯曲造成的。
答案 D3．Which of the following statements about our brain is true?
A．In the long run，our brain probably works harder than our heart.
B．When our brain senses the spinning，we will feel dizzy.
C．The brains of the other mammals are as complex as those of humans.
D．Our feelings and emotions come from the most developed area in our brain.
解析 细节理解题。根据第二个标题下的第三句“But，in the long run，your brain...”可知答案为A项。此题最易误选B项，根据第五个标题下的最后一句可知，眩晕是由于 “你已经不动了，而你的大脑认为你还在动”的错觉引起的。
答案 A4．What is the main purpose of the selection?
A．To give advice on how to stay healthy.
B．To provide information about our body.
C．To challenge new findings in medical research.

解析 写作意图题。考生易误选D项，但是在医学领域，概括失误。文章主要涉及我们身体的问题，包括身体的、情绪的等等。故选择B项较全面。
答案 B阅读理解阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。Parents should ban electronic media during mealtimes and after bedtime as part of a comprehensive “family media use plan”, according to new recommendations from the American Academy of Pediatrics. “Excessive media use is associated with obesity, poor school performance, aggression and lack of sleep”, said Marjorie Hogan, co-author of the new policy.
Families should have a no-device rule during meals and after bedtime, the guidelines say. Parents should also set family rules covering the use of the Internet, cellphones, including, perhaps, which sites can be visited, and who can be called. The policy also restated the existing recommendations: Kids should limit the amount of screen time for entertainment to less than two hours per day; children younger than 2 shouldn’t have any TV or Internet exposure. Also, televisions and Internet-accessible devices should be kept out of kids’ bedrooms.
Doctors say parents need to obey the family rules, too, to model healthy behavior. That, some say, may be the toughest part. “If you go to any restaurant, Family 3.0 is Mom and Dad on their devices and the kids on theirs”, says Donald, a pediatrician(小儿科医师) and an AAP spokesman. 揥ho is talking to each other??rn
Children aged from 8 to 18 spent an average of 7 hours and 38 minutes a day consuming media for fun, including TV, music, video games and other content in 2009, according to a 2010 report from the Kaiser Family Foundation. The report was based on a survey of 2002 third through twelfth graders, 702 of whom completed a seven-day media use diary. That was up about an hour and 17 minutes a day from five years earlier. About two-thirds of 8 to 18-year-olds said they had no rules on the amount of time they spent watching TV, playing video games or using the computer, the Kaiser report found.
Use of mobile devices by young kids has soared. A new report from Common Sense Media, a child-advocacy group based in San Francisco, found that 17% of children 8 and younger use mobile devices daily, up from 8% in 2011.

A. It’s beneficial to their health.
B. It’s essential to parenting their kids.
C. It’s beneficial to their work.
D. It’s essential to develop good relationship with their kids.
3. What can be inferred according to the report from the Kaiser Family Foundation?
A. The majority of the surveyed kids can use electronic devices as they like in their homes.
B. The report was based on the statistics in 2002.
C. 702 of the surveyed kids completed a seven-day media use diary.
D. Kids are spending less and less time using media for fun.
4. What can be the best title of the passage?

阅读下列四篇短文，从每小题后所给的A,B,C或D四个选项中，选出最佳选项。
A new argument has been put forward as to whether penguins are disturbed by the presence of tourists in Antarctica.
Previous research by scientists from Keil University in Germany monitored Adelie penguins and noted that the birds’ heart rates increased dramatically at the sight of a human as far as 30 meters away. But new research using an artificial egg, which is equipped to measure heart rates, disputes this. Scientists from the Scott Polar Research Institute at Cambridge say that a slow moving human who does not approach the nest too closely, is not viewed as a threat by penguins.
The earlier findings have been used to partly explain the 20 per cent drop in populations of certain types of penguins near tourist sites. However, tour operators have continued to insist that their activities do not adversely affect wildlife in Antarctica, saying they encourage non-disruptive behavior in tourists, and that the decline in penguin numbers is caused by other factors.
Amanda Nimon of the Scott Polar Research Institute spent three southern hemisphere summers at Cuverville Island in Antarctica studying penguin behavior towards humans. “A nesting penguin will react very differently to a person rapidly and closely approaching the nest,” says Nimon. “First they exhibit large and prolonged heart rate changes and then they often flee the nest leaving it open for predators (掠夺者) to fly in and remove eggs or chicks.” The artificial egg, specially for the project, monitored both the parent who had been ‘disturbed’ when the egg was placed in the nest and the other parent as they both took it in turns to guard the nest.
However, Boris Culik, who monitored the Adelie penguins, believes that Nimon’s findings do not invalidate his own research. He points out that species behave differently – and Nimon’s work was with Gentoo penguins. Nimon and her colleagues believe that Culik’s research was methodologically flawed because the monitoring of penguins’ responses needed capturing and restraining the birds and fitting them with beart-rate transmitters. Therefore, argues Nimon, it would not be surprising if they became stressed on seeing a human subsequently.
1. According to the passage, what overall message is presented?
A. No firm conclusions are drawn.
B. Neither Culik’s nor Nimon’s findings are of much value.
C. Penguin reduction is closed related to tourist behavior.
D. Tourists are not responsible for the fall in penguin numbers.
2. Which ONE argument of the following is stated in the passage?
A. Penguins are harder to research when they have young.
B. Tour operators should encourage tourists to avoid Antarctica.
C. Not all penguins behave in the same way.
D. Penguins need better protection from tourists.
3. What do you notice about the views presented in the passage?
A. They are groundless.
B. They are factual.
C. They are descriptive.
D. They are conflicting.
69. What does the underlined word (final line) probably mean?
A. later on
B. carmly
C. separately
D. in the same place

A German study suggests that people who were too optimistic about their future actually faced greater risk of disability or death within 10 years than those pessimists who expected their future to be worse.
The paper, published this March in Psychology and Aging, examined health and welfare surveys from roughly 40,000 Germans between ages 18 and 96.The surveys were conducted every year from 1993 to 2003.
Survey respondents (受访者) were asked to estimate their present and future life satisfaction on a scale of 0 to 10, among other questions.
The researchers found that young adults (age 18 to 39) routinely overestimated their future life satisfaction, while middleaged adults (age 40 to 64) more accurately predicted how they would feel in the future.Adults of 65 and older, however, were far more likely to underestimate their future life satisfaction.Not only did they feel more satisfied than they thought they would, the older pessimists seemed to suffer a lower ratio (比率) of disability and death for the study period.
“We observed that being too optimistic in predicting a better future than actually observed was associated with a greater risk of disability and a greater risk of death within the following decade，” wrote Frieder R．Lang, a professor at the University of ErlangenNuremberg.
Lang and his colleagues believed that people who were pessimistic about their future may be more careful about their actions than people who expected a rosy future.
“Seeing a dark future may encourage positive evaluations of the actual self and may contribute to taking improved precautions(预防措施)，”the authors wrote.
Surprisingly, compared with those in poor health or who had low incomes, respondents who enjoyed good health or income were associated with expecting a greater decline.Also, the researchers said that higher income was related to a greater risk of disability.
The authors of the study noted that there were limitations to their conclusions.Illness, medical treatment and personal loss could also have driven health outcomes.
However, the researchers said a pattern was clear.“We found that from early to late adulthood, individuals adapt their expectations of future life satisfaction from optimistic, to accurate, to pessimistic，” the authors concluded.
1．According to the study, who made the most accurate prediction of their future life satisfaction?
A．Optimistic adults.
B．Middleaged adults.
C．Adults in poor health.
D．Adults of lower income.
解析 细节理解题。由文章第四段第一句话“The researchers found that young adults (age 18 to 39) routinely overestimated their future life satisfaction, while middleaged adults (age 40 to 64) more accurately predicted how they would feel in the future.”可知中年人可以更加精确地预测他们的未来。故选B项。
答案 B．Pessimism may be positive in some way because it causes people________.
A．to fully enjoy their present life
B．to estimate their contribution accurately
C．to take measures against potential risks
D．to value health more highly than wealth
解析 细节理解题。由第六、七段中的关键信息“...people who were pessimistic about their future may be more careful about their actions...”及“...contribute to taking improved precautions(预防措施)．..”可知对未来持悲观态度的人会对他们的行动更加小心并且采取一些预防措施，故选C项。
