Ⅰ.阅读理解
(2019·重庆市第一中学高二上学期期中)As you bite down a delicious piece of fish, you probably don't think about what the fish itself ate－but perhaps you should.More than 50 species of fish have been found to eat plastic trash at sea.This is bad news, not only for fish but also for humans who rely on fish for food.
Fish don't usually die as a direct result of feeding on the large quantities of plastic trash floating in the oceans.But that doesn't mean it's not harmful for them.Some negative effects that scientists have discovered when fish eat plastic include reduced activity rates and weakened schooling behavior, as well as compromised liver function.This is troubling because people eat fish that have eaten plastic.Numerous species have been sold for human consumption, including mackerel, striped bass and sturgeon in their stomachs.
It is well known that plastic trash causes a serious threat to sea animals, but we are still trying to understand why animals eat it.Typically, research has concluded that sea animals visually mistake plastic for food.While this may be true, the full story is probably more complex.For example, in a recent study, we showed that plastic trash may smell attractive to sea organisms.That study focused on seabirds, but now my co-authors and I have found that plastic trash has a similar effect on anchovies (凤尾鱼)．
When we started the experiment, we did not know whether adult anchovies used their sense of smell to find food at all, let alone whether smell might lead them to eat plastic.To test our hypothesis that it would, we put krill (磷虾) or plastic trash and clean plastic in seawater for several hours.We then filtered our krill and plastic “tea”， presented it to the anchovy schools, and observed their behavior.When we put seawater scented with krill into the tank, the anchovies responded as if they were searching for food.When we presented them with seawater scented with smells of plastic trash, the schools responded in nearly the same way, moving as if they were searching for food.
This research confirms two things.First, we showed that northern anchovies use smells to locate food.This study also suggests that our consume-and-dispose culture is coming back to upset us via the fish we eat.
In fact, everyone can do something right now about ocean-plastic pollution by avoiding single-use plastic items and recycling plastic upon disposal.There is more work to be done.
