TPO30口语TASK6原文
When we humans walk from place to place. We move on the earth surface, across the earth surface. Many animals, of course, doing the same thing. Horses and dogs and cows and so on. all move on the surface, across the surface of the earth. But there are also quite a few of animals that have ability move from place to place underground, beneath the earth surface. These moving around underground is known as subsurface locomotion.
Subsurface locomotion has number of benefits. One benefit of subsurface locomotion is that enable animals to minimized their exposure to extreme temperatures. This is very helpful for animals that living areas was harsh climates where could be very dangerous to spend large amount of times on the surface. For example, in the Sahara desert in Africa, there is a type of lizard that able to live beneath the surface, through the sand very quickly. Because this lizard can move so easily and so quickly underground, It doesn't have to travel on the surface where would be expose to dangerously high temperatures.
Another benefit of subsurface locomotion is that can help animals capture prey. That's because animals on the surface can't see predators that approaching underground. Our lizard and Sahara desert is again a good example. The way works is when the insect is walking nearby the surface, it produces vary subtle vibrations in the sand. When the lizard sense these vibrations, it moves very quickly underground where can't be seen toward the source of vibrations is. then suddenly pops up right up under the insect and catches completely by surprise.。
