Popeye the Sailor first became a popular cartoon in the 1930s.The sailor in that cartoon ate lots of spinach to make him strong. People watched him, and they began to buy and eat a lot more spinach. Popeye helped sell 33 percent more spinach than before! Spinach became a necessary part of many people’s diets. Even some children who hated the taste began to eat the vegetable.
Many people thought that the iron in spinach made Popeye strong, but this is not true. Spinach does not have any more iron than any other green vegetable.
People only thought spinach had a lot of iron because the people who studied the food made a mistake. In the 1890s, a group of people studied what was inside vegetables. This group said that spinach had ten times more iron than it did. The group wrote the number wrong, and everyone accepted it.
Today, we know that the little iron that is in spinach cannot make a difference in how strong a person is. However, spinach does have something else which the body needs—folic acid.
It is interesting to point out that folic acid can help make a person strong. Maybe it was really the folic acid that made Popeye strong all along.

解析试题分析：从二十世纪三十年代动画片《大力水手》的播映以来，菠菜成了人们餐桌上必不可少的一道菜，人们都认为菠菜所含的铁会赋予人力量。事实上，菠菜里含的铁并不比别的蔬菜多，只是菠菜中的叶酸才能够使人身体强壮，在本文中作者揭示了这一事实。
【小题1】B主旨大意题。文章开头提出《大力水手》的播映使得人们一致认为菠菜会给人神奇的力量，然后下文指出this is not true.，接下来作者讲述了有关菠菜的事实，由此可知文章中心内容是纠正人们对于菠菜错误的认识，故答案选B。
【小题2】A推理判断题。动画片中的大力水手吃了菠菜后会力大无穷，看过这个动画片的人们也把菠菜当成了他们餐桌上一道必不可少的菜，由此推断人们认为菠菜真的会让他们身体强壮，所以选A。
【小题3】D细节理解题。根据文章第三段This group said that spinach had ten times more iron than it did. The group wrote the number wrong, and everyone accepted it.可知研究人员提出了菠菜比其他绿色蔬菜含铁更多的观点，答案选D。
【小题4】B细节理解题。根据文章末段It is interesting to point out that folic acid can help make a person strong. Maybe it was really the folic acid that made Popeye strong all along. 可知叶酸会给人提供能量，或许大力水手的力量就是由此而来的，故答案选B。
【小题5】A推理判断题。根据文章第四段spinach does have something else which the body needs—folic acid.可知folic acid（叶酸）是存在于菠菜中的，由此推断答案选A。

(2013·高考新课标全国卷Ⅱ，C)Given that many people’s moods (情绪)are regulated by the chemical action of chocolate，it was probably only a matter of time before somebody made the chocolate shop similar to a drugstore of Chinese medicine.Looking like a setting from the film Charlie&the Chocolate Factory，Singapore’s Chocolate Research Facility (CRF) has over 100 varieties of chocolates.Its founder is Chris Lee who grew up at his parents’ corner store with one hand almost always in the jar of sweets.
If the CRF seems to be a smart idea，that’s because Lee is not merely a seasoned salesperson but also head of a marketing department that has business relations with big names such as Levi’s and Sony.That idea surely results in the imagination at work when it comes to making different flavored (味道) chocolates.
The CRF’s produce is “green ”，made within the country and divided into 10 lines，with the Alcohol Series being the most popular.The Exotic Series－with Sichuan pepper，red bean (豆)，cheese and other flavors－also does well and is fun to taste.And for chocolate_snobs，who think that they have a better knowledge of chocolate than others，the Connoisseur Series uses cocoa beans from Togo，Cuba，Venezuela，and Ghana，among others.
【小题1】What is good about chocolate?
| A．It serves as a suitable gift. |
| B．It works as an effective medicine. |
| C．It helps improve the state of mind. |
| D．It strengthens business relations. |

Today, the biggest killers stem as much from our lifestyles as from bacteria and viruses. One of the worst of these is heart disease, and specifically high blood pressure. It’s a slow, but efficient killer that robs many people of what should be the last 10, 20 or 30 years of their lives.
Scientists are claiming that they have now separated unusual ingredients in a rare seaweed discovered by fishermen off the coast of Korea that offer incredible health benefits—including the ability to restore blood pressure to normal levels.
Dr. Haengwoo Lee, a famous biochemist conducted a clinical study on these two ingredients. The first is Seanol, an extremely rare seaweed extract(浓缩物) from Ecklonia Cava that's proven to be 100 times more powerful than any land-based antioxidant(抗氧化剂). That's because it stays working in your body for 12 hours, compared to land-based antioxidants that work for 30 minutes. "Its secret is its make-up of special chemicals that are a huge 40% fat soluble( 可溶的)," Dr. Lee explains. "Unlike nearly all land-based antioxidants that are water soluble, Seanol's protective compounds can get into things like the fatty tissues of your brain and penetrate（渗透） all three layers of your cells, including the outside, the oil-based cell membranes（细胞膜）, and your DNA." Indeed, Seanol is so powerful, it's the only FDA-approved Ecklonia Cava marine-algae (海藻) extract in existence.
The second ingredient is Calamarine, a deep-sea omega-3 discovery that delivers 85% more DHA omega-3s to your heart, brain, joints, and eyes. It's known to reduce the problems from tiredness and poor memory, joint pain, mood swings and depression.
With that research in mind, Dr. Lee combined Seanol and Calamarine with a high dose of vitamin D to form Marine-D3, the newest supplement in the fight against age-related illnesses and high blood pressure.
Dr. Lee found that Calamarine delivers some of the greatest concentration of omega-3s known to science. Combined with Seanol's ability to reduce body inflammation(炎症), as well as help cells get the nutrients they need to thrive, stay healthy and protected, Marine-D3 is able to boost a body's entire well being.
The makers of Marine-D3 are so confident that you'll see fast dramatic results from this product, that if you aren't happy after two full months, simply return the unused portion and they'll buy it back. They'll even give you ten dollars extra just for giving it an honest try! That kind of faith, combined with Dr. Lee's exhaustive research, shows that Marine-D3 really is a one-of-a-kind product.
【小题1】From the first paragraph we can infer that ________.
| A．Our lifestyles result from the biggest killers |
| B．our lifestyles do less harm to our bodies than bacteria and viruses do. |
| C．High blood pressure left untreated may cause shorter life. |
| D．Heart disease is incurable. |
| A．Fishermen off the coast of Korea have isolated unusual ingredients. |
| B．Scientists have purified ingredients that can lower blood pressure to normal standard. |
| C．Scientists discovered a rare seaweed. |
| D．Scientists have imagined a medicine that treat blood pressure. |
| A．According to FDA , Seanol reaches the agreed standard. |
| B．Seanol can be fat soluble entirely. |
| C．Seanol is a common seaweed extract fromEcklonia Cava. |
| D．Seanol's protective compounds can get into all things like the fatty tissues of your brain. |
| A．pessimistic | B．indifferent | C．doubtful | D．Optimistic |

Life on Mars could become a reality and it could happen in your lifetime.
A welcoming planet
Scientists say Earth’s neighbor Mars, a bright red planet about half Earth’s size, is the most likely to support human life. Mars even has frozen water on its surface.
Since the late 1990s, NASA has been exploring Mars using remote-controlled vehicles（装置）. Most recently Curiosity, a car-size vehicle, traveled through space on an unpiloted spacecraft(航天器) and landed on Mars in August 2012. Directed by NASA scientists , the vehicles move on the surface, taking pictures , collecting and analyzing soil, and looking for signs of life.
But what about human explorers? Plans are already in the works to send astronauts to Mars as soon as the mid-2030s.
_____________________________________
But before you start packing your bags, let’s consider the challenges. For starters, Mars is far away. Just getting there could take up to 10 months.
Scientists already know that time away from Earth’s gravity harms the human body. Bones and muscles get weaker. The body produces less blood. What damage would months and months of living in space do?
And then there is the matter of water, oxygen, food and fuel. Scientists will have to find solutions to these problems, or the first humans on Mars won’t survive very long in their new home.
Tiny Dangers
There’s another tinier risk. It’s so tiny that you can’t even see it: germs.
Some scientists believe that our germs could pollute the whole planet of Mars. Potentially killing Martian life before we have the chance to discover it. Worse, there is a small but terrifying chance that any microscopic life already there might be harmful to us .
Worse still, if any of those Martian germs(火星细菌) were brought back to Earth, the result could be disastrous. Animals, plants, and people could be wiped out.
Worth the $$$?
A more practical concern is the cost. The price could approach $ 1 trillion(万亿). How can we justify spending that much when so many problems—poverty, disease—could use the cash here on Earth?
【小题1】Which of the following is TRUE according to the “A welcoming planet” part?
| A．Mars is a little bigger than Earth. |
| B．There are flowing rivers on Mars. |
| C．People haven’t been to Mars so far. |
| D．Scientists have discovered signs of life on Mars. |
| A．Living in space. | B．Limited resources. |
| C．Extreme conditions. | D．Interesting challenges. |
| A．there is no serious danger |
| B．people won’t be in any danger |
| C．it’s difficult for people to realize the danger |
| D．the danger may be caused by very small things |
| A．Martian germs may be different from those on Earth. |
| B．Martian germs may be brought back to Earth. |
| C．People may carry germs to Mars. |
| D．There may be germs on Mars. |
| A．People | B．History | C．Science | D．Business |

Speaking two languages rather than just one has obvious practical benefits in an increasingly globalized world．But in recent years, scientists have begun to show that the advantages of bilingualism （双语能力） are even more important than being able to converse with a wider range of people．Being bilingual, it turns out, makes you smarter．It can have a deep effect on your brain, improving skills not related to language and even protecting against a serious mental disorder in old age．
This view of bilingualism is different from the understanding of bilingualism through much of the 20th century．Researchers, educators and policy makers long considered a second language to be an interruption that prevented a child's school work and ability to think and understand things．They were not wrong about the interruption: there is ample evidence that in a bilingual \s brain both language systems are active even when he is using only one language, thus creating situations in which one system disturbs the other．But this interruption, researchers are finding out, isn't so much a disturbance．It forces the brain to solve inside conflict, giving the mind a workout that strengthens its thinking muscles．
The key difference between bilinguals and monolinguals may be more basic: a heightened ability to monitor the environment．"Bilinguals have to switch languages quite often—you may talk to your father in one language and to your mother in another language," says Albert Costa, a researcher at the University of Pompea Fabra in Spain．
"It requires keeping track of changes around you in the same way that we monitor our surroundings when driving．" In a study comparing German-Italian bilinguals with Italian monolinguals on monitoring tasks, Mr．Costa and his colleagues found that the bilingual subjects not only performed better, but they also did so with less activity in parts of the brain involved in monitoring, showing that they did better in it．
【小题1】From the passage we can learn that experts used to believe that ______．
| A．interruption forced a bilingual's brain to strengthen its thinking ability |
| B．a second language stopped children's studying as well as mental development |
| C．using two languages annoyed the children who have trouble in learning skills |
| D．language systems were busy in a bilingual's brain when he was using languages |
| A．change | B．use | C．speak | D．study |
| A．Cautious． | B．Doubtful． | C．Concerned． | D．Favourable． |
| A．How Bilinguals Use Languages |
| B．What Bilingualism Is Really about |
| C．Why Bilinguals Are More Intelligent |
| D．When People Learn a Second Language |

About ten men in every hundred suffer from color blindness in some way. Women are luckier; only about one in two hundred is affected in this matter. Perhaps, after all, it is safer to be driven by a woman!
There are different forms of color blindness. In some cases a man may not be able to see deep red. He may think that red, orange and yellow are all shadows of green. Sometimes a person cannot tell the difference between blue and green. In rare cases an unlucky man may see everything in shades of green － a strange world indeed.
Color blindness in human beings is a strange thing to explain. In a single eye there are millions of very small things called “cones”. These help us to see in a bright light and to tell difference between colors. There are also millions of “rods”, but these are used for seeing when it is near dark. They show us shape but no color.
Some insects have favorite colors. Mosquitoes prefer blue to yellow. A red light will not attract insects, but a blue lamp will. In a similar way human beings also have favorite colors. Yet we are lucky. With the aid of the cones in our eyes we can see many beautiful colors by day, and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible colors around us.
【小题1】The passage is mainly about _____________.
| A．color and its surprising effects. |
| B．women being luckier than men |
| C．danger caused by color blindness |
| D．color blindness |
| A．tell different shapes | B．see in a weak light |
| C．kill mosquitoes | D．tell orange from yellow |
| A．Women are more careful. |
| B．There are fewer color-blind women |
| C．Women are fonder of driving than men. |
| D．Women are weaker but quicker in thinking. |
| A．Not all of them have the same problem in recognizing color. |
| B．None of them can see deep red. |
| C．None of them can tell the difference between blue and green. |
| D．All of them see everything in shades of green. |
| A．red light | B．yellow light | C．blue light | D．green light |

Thoughts claim our attention continuously, and waste our time and energy on unimportant and useless matters. They actually rule our life. We have become so used to this slavery, that we take it for granted, and have become unconscious of this habit, except on certain occasions.
While breathing, we do not need to pay attention to each inhalation and exhalation. We become conscious of the process of breathing only when we have some difficulty with breathing, such as when our nose is blocked, due to a cold, or when we are in an unventilated(不通风的) room.
It is the same with thinking. We become conscious of the constant onslaught of our thoughts, and of our inability to calm them down, only when we need to concentrate, solve a problem or study. We are also aware of them when we have worries or fears.
Look at the following familiar situation. You need to study something for an exam. You sit comfortably on the sofa with the book in your hands and start reading. After a while you feel hungry and go to the kitchen to eat something.
You return to read, and then hear your people talking outside. You listen to them for several moments and then bring your attention back to the book.
After a while you feel restless and switch on the radio to listen to some music. You continue to read for a little while, and then remember something that happened yesterday, and you start thinking about it.
When you look at your watch, you are amazed to find out that one complete hour has passed and you have hardly read anything. And at this time, you feel you’re thinking.
This is what happens when one lacks concentration. Imagine what you could have accomplished if you could control your attention and focus your mind!
【小题1】When can you feel you are thinking?
| A．While breathing. | B．While not reading. |
| C．When you need to concentrate. | D．When you waste your time. |
| A．To explain the course of thinking awareness. |
| B．To show how to get ready for an exam. |
| C．To present an example of concentration. |
| D．To emphasize the importance of reading. |
| A．In a guidebook of natural science. |
| B．In the front page of a newspaper. |
| C．In an advertisement part of a magazine. |
| D．In the section of psychology of a magazine. |
| A．the relationship between thoughts and breathing |
| B．how people’s thought and mind work |
| C．what happens when one wants to think |

Dogs wag(摇摆) their tails in different directions depending on whether they are excited and wanting to move forward or threatened and thinking of moving back, a study has found.
Researchers in Italy examined the tail wagging behaviour of 30 dogs, catching their responses to a range of stimuli(刺激物) with video cameras. To conduct the study they chose 15 male dogs and 15 female ones aged between one and six years. The dogs were all family pets whose owners had allowed them to take part in the experiment at Ban University. The dogs were placed in a large wooden box with an opening at the front to allow for them to view various stimuli. They were tested one at a time.
The researchers led by Professor Giorgio Vallortigara of the University of Trieste found that when the dogs were shown their owners—a positive experience—their tails wagged energetically to the right side. When they were shown an unfamiliar human they wagged to the right, but with somewhat less enthusiasm. The appearance of a cat again caused a right-hand side wag, although with less intensity again. The appearance of a large unfamiliar dog, similar to a German shepherd, changed the direction of tail wagging to the left. Researchers supposed the dog was thinking of moving back. When the dogs were not shown any stimuli they tended to wag their tails to the left, suggesting they preferred company. While the changes in the tail wagging were not easily noticed without the aid of video, it was thought that the findings could help people judge the mood of dogs. Computer and video systems, for example, could be used by professional dog trainers to determine the mood of dogs that they were required to approach.
【小题1】.The video cameras were used to catch the dogs’ responses because ___________ .
| A．it was easier to catch the dogs’response changes in the tail wagging |
| B．the dogs were put in the wooden boxes and tested one at a time. |

| A．surprise | B．worry | C．excitement | D．interest |
| A．wag to the left | B．wag to the right |
| C．not wag at all | D．wag to the left and then to the right |
| A．the dogs | B．the trainers | C．the systems | D．the rescarchers |

Many people in the world live in big cities, which are often dirty and difficult places to live. So, some cities will get bigger. They will also get higher, and lower, because people will begin to live under the ground as well as in tall buildings. Scientists also say that men can begin to live in cities under the sea, when there is not enough space on the land. Of course, these new cities will be very expensive, and difficult to build, but they are not impossible. Already, some countries are building places to live under the ground so their people can go there if there is a new war. There are underground cities in Switzerland（瑞士）and China, built by the government（政府）to help some of the people live during a great war.
But will people change if they live under the ground for a long time？For example some fish go blind if they live in the dark sea for a long time. People will not go blind, because there will be light underground, but they may change in some way. Scientists say that people who live in cities today are losing their senses of smell, touch and taste. They can’t smell the dirty air, they can’t taste the chemicals（化学制剂）in their food. These senses are not as strong as before, when people lived in the country and grew their own food. The city has changed that. What will the underground city change in everyone？
【小题1】People will live under the ground because _________．
| A．it’s neither hot nor cold there |
| B．they’ll be afraid of the war |
| C．there’ll be less space on the ground |
| D．they’ll make their life comfortable |
| A．when summer comes |
| B．when a war breaks out |
| C．because they think it’ll be safer for them |
| D．when they’re fed up with the life on the land |
| A．There’ll be enough light under the ground |
| B．It’ll be easy to go upstairs |
| C．Glasses will be sold under the ground |
| D．Medicine will be supplied for free |
| A．the world are polluted |
