Passage 6

The U.S. dollar was supposed to be at the end of its rope. Kicking the bucket. A dying symbol of a dying empire. Well, maybe not. The dollar continues to _1_ gloom-and-doom predictions. After a swoon (低迷）last year, the dollar is again enjoying a major _2_. The U.S. dollar index, which measures the dollar’s value against other major currencies, is just off an eight-month high. The main reason behind the dollar’s recovery is actually no real surprise at all. There is no _3_ able to replace the dollar as the world’s No.l currency. What makes currencies so fascinating is that their perceived value is always relative to other currencies. Sure, the U.S. budget deficit is _4_, the government’s debt is increasing, and Wall Street is still repairing itself. But the dollar remains the prettiest of a flock of ugly ducklings. Is any other major industrialized economy _5_ better off than the U.S.？ Not really. Just about the _6_ developed world is suffering with the same problems. That’s why when investors get nervous, they still rush to the good old dollar. The dollar wins because no one else is really in the game. The euro has been exposed as a _7_. Only a few months ago, economists truly believed the euro could _8_ the dollar as the top reserve currency. Now experts are questioning if the euro has a future at all. The Greek debt crisis has _9_ that the euro is only as strong as its weakest link. Maybe over the next 20 or 30 years，the dollar will slowly lose the _10_ status it holds today. That process, however, could well be driven by the appearance of new rivals.

he specialists in an embarrassing position because he is often unable to give a direct answer to this simple question.

But actually this question is not as simple as it seems. There are thousands of different kinds of fishes, and they vary a great deal in size and life span. Moreover, it is not easy to find out just how long a fish lives in its natural state. We can find out how old a fish is by studying its scales, but we cannot say how much more time it would live if we had not caught it.

We may rear fishes and record their life span but we cannot be sure that this is the length of time they would have lived, had they been left alone.

We may make marking to show how fast the fishes grow so that we can calculate the age of the largest on record, but unless this large fish dies of old age we are still not in a position to know its natural life span.

Unlike human beings, fishes do not stop growing when they reach maturity. They continue to grow as long as they live, although the rate of growth slows down in mature fishes.

People often ask the specialist on fishes regarding its _______.

A.size

B.life span

C.age
