Anyone caring about their health will be able to speak out a few of the major vitamins, and possibly take an educated guess at what they do. Vitamin C, found in oranges and other fruit and vegetables, is important for wound repair. And the much-talked-about “sunshine” vitamin D, produced by the skin in response to UV light, is essential for strong bones.
But what about vitamin P? It might well have you scratching your head. And that's not surprising: the term was first coined in the 1930s to describe a small group of compounds that provide pigment (天然色素) to plants, and were believed to have health benefits. A century later, these compounds are now better known as flavonoids (类黄酮).
Today, scientists have identified between 4,000 and 6,000 different kinds and we now know they are responsible for many of the flavors and smells of fruit and vegetables and also that they protect them from invaders such as pests and bacteria.
They are equally important nutrients for the body, helping maintain bones and teeth, and for the production of the protein collagen (胶原), which provides structure to blood vessels, muscles and skin.
They are also said to help the body deal with some of the key drivers of illness, including oxidation (氧化), a natural process by which the body's cells age and can become damaged and defective. That means they could help to protect against chronic diseases including cancer and heart disease.
1.What do we know about vitamin P?
A.We would scratch our head if we took it.
B.It refers to the compounds also called flavonoids.
C.It was made into a coin in the 1930s.
D.People didn't think it beneficial in the past.
2.Which is NOT the function of vitamin P for humans according to the passage?
A.Helping maintain bones and teeth.
B.Assisting in producing protein collagen.
C.Accelerating the circulation of the blood.
D.Aiding the body to handle the main factors of illness.
3.Which of the following best explains “defective” underlined in the last paragraph?
A.Harmful. B.Discouraged.
C.Vague. D.Deficient.
4.How does vitamin P help slow the aging process?
A.By fighting against oxidation. B.By maintaining bones.
C.By strengthening muscles. D.By protecting against chronic diseases.

高三英语阅读理解中等难度题查看答案及解析
They may be small and not able to speak, but babies are proving their amazing cleverness. Scientists began finding infants’ skills are more than they are supposed to be.
_________
Speaking of music, babies can’t seem to resist it. Not only are their ears turned to the beats, babies can actually dance to the music.
To test babies’ dancing ability, the researchers played recordings of classical music, rhythmic beats and speech to infants, and recorded the results. They also invited professional dancers to analyze how well the babies matched their movements to the music. The babies moved their arms, hands, legs feet and heads in response to the music, much more than to the speech. The finding suggests this dancing ability is innate(与生俱来的) in humans, though the researchers aren’t sure why it becomes weaker later in their life.
Learning Quickly while Sleeping
Babies can learn even while asleep, according to a 2011 study. In experiments with 26 sleeping infants, each just 1 to 2 days old, scientists played a musical tone followed by a puff of air to their eyes 200 times over the course of a half-hour. 124 electrodes(电极) stuck on the head and face of each baby recorded brain activity during the experiments. The babies rapidly learned to foretell a puff of air upon hearing the tone, showing a four-time increase on average in the chances of tightening their eyelids in response to the sound by the end of the experiments.
As newborns spend most of their time asleep, this newfound ability might be crucial to rapidly adapting to the world around them and help to ensure their survival, researchers said.
Judging Characters Well
Judging another person helpful or harmful is crucial when choosing friends. And that ability starts early. Kiley Hamlin of Yale University showed both 6-and 10-month-olds a puppet(木偶) show, in which one character helped another climb a hill. In another scene a third character pushed the climber down. The little ones then got to choose which character they preferred. For both age groups, most babies chose the helper character. This character-judging ability could be baby’s first step in the formation of morals, Hamlin thought.
1.Which of the following subtitles can fill in the underlined blank?
A.Dancing to Music |
B.Babies’ Amazing Abilities |
C.Learning to Dance Quickly |
D.Born to Dance |
2.The underlined word “it” in the third paragraph refers to______.
A.the finding |
B.the dancing ability |
C.the response |
D.the baby |
3.The experiment with 26 sleeping infants prove that_______.
A.babies can learn even while asleep |
B.babies can respond to the world around them |
C.babies can tighten their eyelids in response to the sound |
D.babies can communicate with others while asleep |
4.In the last experiment, most babies chose the helper character, showing that________.
A.babies can judge a person helpful or harmful |
B.babies love to see a puppet show |
C.babies were born to help others |
D.babes have learned to help others |
