Among the dead in South Asia’s tsunami were many tourists at Sri Lanka’s national wildlife park at Yala. But very few of the park’s animals — elephants, buffaloes, monkeys and wild cats — appear to have died. There are theories that animals can sense natural disasters and flee to safety.

First, it’s possible that the animals may have heard the quake before the tsunami hit. The underwater rupture likely produced sound waves known as infrasound or infrasonic sound. Humans can’t hear infrasound, but many animals including dogs, elephants, tigers and pigeons can.

A second early warning sign the animals might have sensed is ground vibration. The massive quake would have produced vibrational waves known as Rayleigh waves. These vibrations move through the ground like waves move on the surface of the ocean but faster. They travel at ten times the speed of sound. The Rayleigh waves would have reached SriLanka hours before the water hit. Mammals, birds, insects and spiders can sense Rayleigh waves. So the animals at Yale might have felt the Rayleigh waves and then run to higher ground.

But what about humans? While we can’t hear infrasound, we can feel it, although we don’t necessarily know we’re feeling it. We also experience Rayleigh waves by special sensors in our joints, which exist just for that purpose. Sadly, it seems we don’t pay attention to the information when we get it. Maybe we screen it out because there’s so much going on before our eyes and in our ears. Humans have a lot of things on our minds and usually that works out OK.

Notes:

tsunami  n. 海啸

infrasound  n. 次声

vibration  n. 振动,颤动

Choose the best answers according to the above:

Why did few animals at Yala die when the tsunamis that caused a huge number of human deaths hit?

A. Because the animals were staying at a higher place in the park.

B. Because the animals were able to run much faster than human beings.

C. Because human beings cannot hear the infrasonic sound.

D. Because the animals might have picked up the danger signals and ran away.

Which of the statements about “Ravleigh waves” is true?

A. Rayleigh waves are massive vibrational waves that usually cause quakes or tsunamis.

B. Rayleigh waves move on the ocean surface at a speed ten times that of sound waves.

C. Rayleigh waves can be felt both by animals and human beings.

D. Rayleigh waves, just like infrasonic sound, can only be felt by animals.

When a tsunami hits, it is possible that ____.

A. we can’t feel the infrasound so we can’t be informed of the danger

B. we can feel Rayleigh waves as well as infrasound so we are able to escape the danger like animals

C. we were so busy with things on our minds that we feel neither infrasound nor Rayleigh waves

      D. we think nothing of the information of its coming even though we can also get it

What does the underlined word “that” in the last sentence refer to?

A. Screening out the information.

B. There being so much going on before our eyes and in our ears.

C. Having a lot of things on our minds.

D. Paying attention to the information.

Maybe ten-year-old Elizabeth put it best when she said to her father. “But Dad, you can't be healthy if you're dead.”

    Dad , in a hurry to get home before dark so he could go for a run, had forgotten to wear his safety belt--a mistake 75% of the US population make every day. The big question is why.

    There have been many myths about safety belts ever since their first appearance in cars some forty years ago. The following are three of the most common.

    Myth( 神话)Number One: It's best to be “thrown clear” of a serious accident.

    Truth: Sorry , but any accident serious enough to “throw you clear” is also going to be serious enough to give you a very bad landing. And chances are you'll have traveled through a windshield(挡风玻璃)or door to do it. Studies show that chances of dying after a car accident are twenty-five times greater in cases where people are “thrown clear.”

  Myth Number Two: Safety belts “trap” people in cars that are burning or sinking in water.

  Truth: Sorry again. but studies show that people knocked unconscious(昏迷) due to not wearing safety belts have a greater chance of dying in these accidents. People wearing safety belts are usually protected to the point of having a clear head to free themselves from such dangerous situations, not to be trapped in them.

  Myth Number Three: Safety belts aren't needed at speeds of less than 30 miles per hour

  Truth: when two cars traveling at 30 mph hit each other. An unbelted driver would meet the windshield with a force equal to diving headfirst into the ground from a height of 10 meters.

Why did Elizabeth say to her father, “But. Dad, you can't be healthy if you're dead”?

A. He was driving at great speed.

B. He was running across the street.

C. He didn't have his safety belt on.

D. He didn't take his medicine on time.

The reason Father was in a hurry to get home was that he_____.

A. wasn't feeling very well

B. hated to drive in the dark

C. wanted to take some exercise

D. didn't want to be caught by the police

According to the text, to be “thrown clear” of a serious accident is very dangerous ,because you _____.

A. may be knocked down by other cars

B may get seriously hurt being thrown out of the car

C. may find it impossible to get away from the seat

D. may get caught in the car door

Some people prefer to drive without wearing a safety belt because they believe___.

A. the belt prevents them from escaping in an accident

B. they will be unable to think clearly in an accident

C. they will be caught when help comes

D. cars catch fire easily

What is the advice given in the text?

A.Never drive faster than 30 miles an hour.

B. Try your best to save yourself in a car accident.

C. Never forget to wear the safety belt while driving.

D. Drive slowly while you're not wearing a safety belt.
