Fish Ears Tell Fish Tales

  Fish have ears. Really. They’re quite small and have no opening to the outside world carrying sound through the body. For the past seven years, Simon Thorrold, a university professor, has been examining fish ears, small round ear bones called otoliths (耳石).

  As fish grow, so do their otoliths. Each day, their otoliths gain a ring of calcium carbonate (碳酸钙). By looking through a microscope and counting these rings, Thorrold can determine the exact age of a young fish. As a fish gets older, its otoliths no longer get daily rings. Instead, they get yearly rings, which can also be counted, giving information about the fish’s age, just like the growth rings of a tree.

  Ring counting is nothing new to fish scientists. But Thorrold has turned to a new direction. They’re examining the chemical elements (元素) of each otolith ring.

  The daily ring gives us the time, but chemistry tells us about the environment in which the fish swam on any given day. These elements tell us about the chemistry of the water that the fish was in. It also says something about water temperature, which determines how much of these elements will gather within each otolith ring.

  Thorrold can tell, for example, if a fish spent time in the open ocean before entering the less salty water of coastal areas. He can basically tell where fish are spending their time at any given stage of history.

  In the case of the Atlantic croaker, a popular saltwater food fish, Thorrold and his assistant have successfully followed the travelling of young fish from mid-ocean to the coast, a journey of many hundreds of miles.

  This is important to managers in the fish industry, who know nearly nothing about the whereabouts of the young fish for most food fish in the ocean. Eager to learn about his technology, fish scientists are now lending Thorrold their ears.

What can we learn about fish ears from the text?

 A. They are small soft rings.

 B. They are not seen from the outside.

 C. They are openings only on food fish.

 D. They are not used to receive sound.

Why does the writer compare the fish to trees?

 A. Trees gain a growth ring each day.

 B. Trees also have otoliths.

 C. Their growth rings are very small.

 D. They both have growth rings.

Why is it important to study the chemistry of otolith rings?

 A. The elements of the otoliths can tell the history of the sea.

 B. Chemical contents of otoliths can tell how fast fish can swim.

 C. We can know more about fish and their living environment.

 D. Scientists can know exactly how old a fish is.

How would you understand “fish scientists are now lending their ears”?

 A. They are very interested in Thorrold’s research findings.

 B. They want to know where they can find fish.

 C. They lend their fish for chemical studies.

 D. They wonder if Thorrold can find growth rings from their ears.

One man tells of driving on a long and lonely road, the last 65 miles of it unpaved, in order to watch Indian dances in the state of Arizona. After the dances, he returned to his car only to find that it had a flat tire. He put on the spare and drove to the only service station in that town.
“Do you fix flats?” he inquired of the attendant.
“Yes,” came the answer.
“How much do you charge?” he asked.
With a twinkle in his eye, the man replied, “What difference does it make?”
This is what has been called a “Hobson’s choice”. A Hobson’s choice is a situation that forces a person to accept whatever is offered or go without.
According to Barbara Berliner, the phrase was inspired by sixteenth-century entrepreneur (企业家) Thomas Hobson. There was no choice by the customer — it was strictly Hobson’s choice.
But often we really have a choice, and the choice does make a difference. We may not always believe it. We may feel as if we have no choice, but almost always there is a choice in the matter. And when we realize that we do most things by choice, then we are taking control of our own lives.
Someone challenged me to try an experiment that completely changed my perspective. “For the next seven days,” he said, “eliminate the words ‘I have to’ from your vocabulary and say ‘I choose to’. Don’t say, ‘I have to work late tonight’. Instead, say, ‘I choose to work late’. When you choose to do it, you take control of your life. Instead of saying, ‘I have to stay home’, try ‘I choose to stay home’. The way you spend your time is your choice. You are responsible. You have control.”
In just seven days I was no longer saying “I have to” and I felt better about my decisions. I learned that there is very little in my life I actually have to do. You and I decide to do certain things because we believe that it will be for the best. When we eliminate “I have to” from our vocabularies, we take control.
Try it for a week and you see what happens. I think you’ll see it’s a change for the better.
【小题1】 What did the attendant mean by saying “What difference does it make”?

A.The man didn’t need to pay for the work.
B.It was unnecessary for the man to ask about the price.
C.There was no need for the man to have the tire fixed.
D.The man should keep silent.
【小题2】The author learnt from the experiment that he      .
A.could become more challenging
B.could spend more time relaxing himself
C.should take pleasure in helping others
D.actually changed his attitudes towards life
【小题3】What does the underlined word “eliminate” mean?
A.Remember.B.Repeat.C.Remove.D.Recite.
【小题4】What is the situation where we have a “Hobson’s choice”?
A.We have no choice but to follow.
B.We should often change our choice.
C.We should make preparations before a journey.
D.We should think twice before taking action.
