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?

Humans have long been interested greatly in the idea of being able to walk on water. Sadly, biological facts prevent us ever realizing this dream without artificial aid—we simply weigh too much, and all our weight 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 reach a speed of 20 steps per second to keep moving forward. For humans, we would need huge feet that we could bring up to our ears in order to create enough “hitting”.
But fortunately there is an alternative: cornflour(玉米淀粉). By adding enough of this common thickening agent to water (and it does take a lot), you can create a special mixture that doesn't behave like normal water. Now, if the surface of the water is hit hard enough, particles(微粒) in the water get 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 this 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(救生圈) ready in case you start to sink—and take a bath afterward!

In the future your automobile will run on water instead of gas! You will be able to buy a supercomputer that fits in your pocket! You might even drive a flying car!
For each prediction that has come true today, several others have missed by a mile. Many of these predictions didn’t consider how people would want to use the technology, or if people really needed it in their lives or not. Let’s look at some predictions from the not-too-distant past.
Robot Helpers
Where’s the robot in my kitchen? Nowhere, of course. And he’s probably not coming anytime soon. Robots do exist today, but mostly in factories and other manufacturing environments.
Back in the 1950s, however, people said that by now personal robots would be in most people’s homes.
So why hasn’t it happened? Probably because robots are still too expensive and clumsy. And maybe the idea of robots cooking our dinners and washing our clothes is just too weird. At home we seem to be doing fine without them.
Telephones of Tomorrow
In 1964 an American company introduced the video telephone. They said by the year 2000 most people would have a video phone in their homes. But of course the idea hasn’t caught on yet.
Why? The technology worked fine, but it over—looked something obvious: people’s desire for privacy. Would you want to have a video phone conversation with someone after you just step out of the shower? Probably not---it could be embarrassing! Just because a technology available doesn’t always mean people will want to use it.
And finally, how about that crazy prediction of the flying car? It’s not so crazy anymore! But a flying car remains one of the most fascinating technology ideas to capture our imagination. Keep watching the news, or perhaps the sky outside your window, to see what the future will bring.
64. The whole passage is mainly about ________________.
A. predictions that have come true. B. predictions that haven’t come true.
C. why predictions don’t come true easily. D. what technology will bring about.
65. The author of this passage won’t believe that _________________.
A. predictions needn’t consider people’s practical use of technology.
B. the future isn’t always easy to guess.
C. not all past predictions have come true.
D. many of the high—tech things our parents thought we’d be using by now simply never appeared.
66. The underlined word “weird” probably means __________.
A. wonderful B. stupid C. practical D. strange
67. What does the author think of the flying car?
A. It is too difficult to imagine. B. It is too crazy an idea.
C. It is likely to be made. D. It is often reported in the news.

Not all past predictions have been proven wrong. A few of them have been surprisingly accurate. Some great thinkers predicted the arrival of the credit card, the fax machine and even the internet years before they happened.
