Ⅳ.阅读理解
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 (教授), has been examining fish ears, small round ear bones (骨头) called otoliths.

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 (显微镜) 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 were 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 mid­ocean 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.
1．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.
答案与解析　B　由第一段可知，由于鱼的耳朵对外没有开口，所以在外边看不到。
2．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.
答案与解析　D　作者之所以把鱼和树进行比较，是由于两者都有年轮。
3．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.
答案与解析　C　由第四段第一句话可知，争辩鱼中的化学物质可以知道它们的居住环境。
4．How would you understand “fish scientists are now lending Thorrold 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.
答案与解析　A　由于Thorrold对鱼的耳朵进行了深化的争辩，使人们对鱼的生长环境有了比较多的了解，“科学家们对Thorrold的争辩产生了很大的爱好”。
