The idea of being able to walk on water has long interested humans greatly. Sadly, biological facts prevent us ever accomplishing such a thing without artificial aid---we simply weigh too much, and all our mass pushes down through our relatively small feet, resulting in a lot of pressure that makes us sink.
However, several types of animals can walk on water. One of the most interesting is the common basilisk Basilicus basilicus, a lizard (蜥蜴)native to Central and South America. It can run across water for a distance of several meters, avoiding getting wet by rapidly hitting the water’s surface with its feet. The lizard will take as many as 20 steps per second to keep moving forward. For humans to do this, we，d need huge feet that we could bring up to our ears in order to create adequate w hitting. ’’
But fortunately there is an alternative : cornflour. By adding enough of this common thickening agent to water (and it does take a lot), you can create a “non-Newtonian” liquid that doesn’t behave like normal water. Now, if the surface of the water is hit hard enough, particles(粒子）in the water group together for a moment to make the surface hard. Move quickly enough and put enough force into each step, and you really can walk across the surface of an adequately thick Liquid of cornflour.
Fun though all this may sound, it’s still rather messy and better read about in theory than carried out in practice. If you must do it, then keep the water wings handy in case you start to sink--and take a shower afterward!
1.Walking on water hasn’t become a reality mainly because humans______.
A. are not interested in it
B. have biological limitations
C. have not invented proper tools
D. are afraid to make an attempt
2.What do we know about Basilicus basilicus from the passage?
A. It is light enough to walk on water.
B. Its huge feet enable it to stay above water.
C. It can run across water at a certain speed.
D. Its unique skin keeps it from getting wet in water.
3.What is the function of the cornflour according to the passage?
A. To create a thick liquid.
B. To turn the water into solid.
C. To help the liquid behave normally.
D. To enable the water to move rapidly.
4.What is the author’s attitude toward the idea of humans’ walking on water?
A. It is risky but beneficial.
B. It is interesting and worth trying.
C. It is crazy and cannot become a reality.
D. It is impractical though theoretically possible.

Anyone with a passing interest in their health will be able to rattle__off 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 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. Fast－forward almost a century and these compounds are now better known as flavonoids.
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(有缺陷的). That means they could help to protect against chronic diseases including cancer and heart disease.
1.Which of the following best explains “rattle off” underlined in Paragraph 1?
A.Quickly say. B.Quickly pass.
C.Quickly find. D.Quickly take.
2.What do we know about Vitamin P?
A.We would scratch our head if we took it.
B.It was made into a coin in the 1930s.
C.People didn't think it beneficial in the past.
D.It refers to the compounds also called flavonoids.
3.How many functions of Vitamin P for humans are mentioned?
A.Four. B.Three.
C.Two. D.One.
4.How does Vitamin P help slow the aging process?
A.By dealing with oxidation.
B.By maintaining bones.
C.By strengthening muscle.
D.By protecting against chronic diseases.
