5、t to do.Does this mean that plants talk to each other? Scientists dont know.

35、钟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 u
36、s 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 waters surface
37、with its feet. The lizard will take as many as 20 steps per second to keep moving forward. For humans to do this, wed need huge feet that we could bring up to our ears in order to create adequate hitting.But fortunately there is an alternative: cornflour. By adding enough of this common thickening a
38、gent to water (and it does take a lot), you can create a non-Newtonian liquid that doesnt 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 eac
39、h step, and you really can walk across the surface of an adequately thick liquid of cornflour.Fun though all this may sound, its 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 sh

41、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.46.What is the function of the cornflour according to the passage? A.To create a thick liquid. B.To turn the water into solid.
