The ocean is full of amazing living things. It’s also full of plastic. That’s bad news for deep-diving (深潜的) whales, as they can 1 the plastic for food and eat it. 2 do whales mix plastic up with prey (猎物) A team at the Duke University Marine (海洋的) Lab in the US has been looking into this question. Recently, the team has provided an answer. It comes down to echolocation (回声定位): a 3 process that allows whales to “hear” objects in the darkest depths of the sea.
Some types of whales hunt in the deepest parts of the ocean, where there’s 4 light. It’s too dark for them to see, but they can hear.
First, the whales make a sound, and then they listen. They hear echoes bouncing off (反射) nearby objects. These echoes 5 the whales to hunt. The echoes bounce off prey like squid (鱿鱼), and they also bounce off objects that are not food, like waste. The 6 found that waste and prey cause similar echoes. To the whales, they “sound” the same. That can cause the whales to eat waste.
However, eating waste is 7 for whales.The plastic can build up in their stomachs, preventing food from 8 through their bodies. This can be deadly.
“Plastic 9 influences animals that are so far away from our daily lives,” says Greg Merrill, the lead author of the study. “This problem is really big. People need to make real changes in their daily lives and then find the solutions we need 10 this problem.”

七、任务型阅读。
Kristen Tapping, a student from London South Bank University, has invented a bike wheel that can help clean pollution in the air. It’s called Rolloe.
The wheel uses fins (翼) to pull in air as it turns. It then uses filters (过滤器) to take in polluted air and give off clean air back into the environment. The wheel can filter more air if it goes faster, although it still works at low speed (速度).
Tapping said users would need to change the filter every week or after about 250 kilometers, to make sure the wheel continues to work well. The wheel f its in the front of a standard (标准的) bike and weighs about one kilogram.
Tapping said she was encouraged to create the wheel when she was biking around London. “In traffic, you always notice the pollution: the heat, the gases and the smell,” she said. She predicts that if 10 percent of the riders in London had a Rolloe on their bike, they could filter about 266,865 m3 of air a day, although this has yet to be tested.
A recent report shows that London’s health costs because of air pollution are the highest among all the European cities. The World Health Organization (WHO) has also said that outdoor air pollution causes about 4.2 million deaths around the world each year.
Tapping wants to use the wheel on shared bike projects at first, with the aim of making the wheels available for all bikes to use. She says she would also like to create a wheel that would fit in the back of a bike, as well as making the wheel available in different sizes.

3. Why did Kristen Tapping decide to invent the wheel Rolloe

________________________________________________________________________________________________________________________________________________________________________________
5. What do you think of the wheel Why do you think so
