M:Hey, Michelle. Look what I just found. Right here in the sand.
W:A piece of wood? Oh. Driftwood. Interesting shape... Almost like some sort of modern sculpture.
M:Yeah. And feel how smooth it is.
W:Hmm, Must’ve been in the water a long time. It could’ve been drifting in the ocean currents for months, or even years.
M:In the currents? Doesn’t the wind just blow things around out there?
W:Well, sure. But the currents are always moving, too. Almost like rivers, but underwater rivers, flowing through the ocean.
M:So how do they find out where these currents go? Stick a message in a bottle and throw it in the water?
W:Don’t laugh. In fact, I was reading in a science magazine that oceanographers have released huge numbers of bottles into the ocean over the years. They wanted to map out where the currents would carry them.
M:Say, I’ll bet-after they found out where all those bottles ended up—they could enter all that data into a computer and make a pretty detailed model to show where the currents go.
W:In fact, they did. And they also found a neat way to test that model. There was a freighter carrying sneakers from a factory in Asia. It was caught in a big storm and thousands of pairs of sneakers got dumped in the Pacific Ocean.
M:Really? What a waste!
W:Yeah. Turns out, though, that hundreds of these shoes started washing up on beaches somewhere near Seattle, just about where the computer models had predicted the currents would carry them.
M: Gee. You mean all that stuff I find on the beaches might be part of some big scientific experiment? I thought it was all just trash!
5. What are the speakers mainly discussing?
6. What did the man find on the beach?
7. According to the magazine article, what did scientists put into the ocean?
8. What can be inferred from the story about the sneakers?
选项
A、A storm can change the direction of an ocean current.
B、Common items can be works or art.
C、Not all useful experiments are planned ahead of time.
D、Computers cannot always predict the effects of pollution.
答案
C
解析
装载着运动鞋(sneakers)的货船是因为遇上暴风雨才会导致这些运动鞋掉进了太平洋,后来又被冲到西雅图的海岸,这是一次意外事故,但却恰巧证实了计算机模型对洋流的预测。这件事说明,并非所有有用的实验都是预先计划好的。正确答案是C。
