This is problematic, as at least 700 kinds of ocean animalsincluding sharks, whales, seabirds and turtlescan become caug
12、ht in the stuff or mistake it for a tasty snack.While we know that some ocean animals seem to cat plastic because it looks like jellyfish or some other food sources, less research has been carried out into what plastic smells like to ocean animals. But now, a study from the University of North Carol
13、ina at Chapel Hill has found the coating that naturally builds up on ocean plastics causes the rubbish to give off the smell of food.The researchers took 15 turtles, each around five months old, and placed them in a lab aquarium. They then piped in smells of clean water, clean plastic, turtle food,
14、and plastic that had been soaking in the ocean environment for five weeks. The turtles showed no reaction to the smells of clean water or clean plastic. But when facing ocean soaked plastic or turtle food, they stuck their noses out of the water and showed increased activity.“This finding is importa
15、nt because its the first proof that the smell of ocean plastics causes animals to eat them,” said Dr Kenneth J Lohmann, who took part in the study.“Its common to find a turtle with its stomach full of plastic materials.

17、 them or prevent them from smelling like food,” said Lohmann. “The best thing we can do is to keep plastic from getting into the ocean at all.”8. What is the function of the first paragraph?A.

21、ing into our brains at night could cause problems in getting to sleep and staying asleep.Neuroscientist Michael Scullin from Baylor University and his coworkers used surveys of 199 people, as well as a sleep lab test involving 50 volunteers, to measure the influence of listening to music before bedt
22、ime on sleep.In the survey part of the study, those who regularly listened to music during the day were more likely to report lasting nighttime earworms, which then had a negative effect on sleep quality through the night.

Tests were used to measure the following sleep quality.Earworms were reported throughout the night by the people surveyed, with those taking longer to fall asleep, spending more time in the lig
