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.

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 track 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.

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.

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.

4.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.

5.If the passage goes on, it possibly refers to _________.

A. fish life B. food fish

C. fish industry D. young fish

Hi, everybody. Over the past couple months, most of the political headlines you’ve read have probably been about the government shutdown and the launch of the Affordable Care Act. And I know that many of you have rightly never been more frustrated with Washington.

But if you look beyond those headlines, there are some good things happening in our economy. And that’s been my top priority since the day I walked into the Oval Office.

After decades in which the middle class was working harder and harder just to keep up, and a punishing recession that made it worse, we made the tough choices required not just to recover from crisis, but to rebuild on a new foundation for stronger, more durable economic growth.

Five years later, we have fought our way back. Our businesses have created 7.8 million new jobs in the past 44 months. Another 200,000 Americans went back to work last month.

The American auto industry has come roaring back with more than 350,000 new jobs – jobs churning out and selling the high-tech, fuel-efficient cars the world wants to buy. And they’re leading the charge in a manufacturing sector that has added jobs for the first time since the 1990s – a big reason why our businesses sell more goods and services “Made in America” than ever before.

We decided to reverse our addiction to foreign oil. And today, we generate more renewable energy than ever, more natural gas than anybody, and for the first time in nearly 20 years, America now produces more oil than we buy from other countries.

We decided to fix a broken health care system. And even though the rollout of the marketplace where you can buy affordable plans has been rough, so far, about 500,000 Americans are poised to gain health coverage starting January 1st. And by the way, health care costs are growing at the slowest rate in 50 years.

And one more thing: since I took office, we’ve cut our deficits by more than half. And that makes it easier to invest in the things that create jobs – education, research, and infrastructure.

Imagine how much farther along we could be if both parties were working together. Think about what we could do if a reckless few didn’t hold the economy hostage every few months, or waste time on dozens of votes to repeal the Affordable Care Act rather than try to help us fix it.

In the weeks ahead, I’ll keep talking about my plan to build a better bargain for the middle class. Good jobs. A good education. A chance to buy a home, save, and retire. And yes, the financial security of affordable health care. And I’ll look for any willing partners who want to help.

Because of your hard work and tough sacrifices over the past five years, we’re pointed in the right direction. But we’ve got more work to do to keep moving that way. And as long as I’m President, I’ll keep doing everything I can to create jobs, grow the economy, and make sure that everyone who works hard has a chance to get ahead. Thanks, and have a great weekend.
