Question

    Blue Planet II's latest episode(一集) focuses on how plastic is having a disastrous effect on the ocean and slowly poisoning our sea creatures. Researchers recently also found that sea creatures living in the deepest place on Earth, the Mariana Trench，have plastic in their stomachs. Indeed, the oceans are drowning in plastic．

Though it seems now that the world couldn't possibly function without plastics， plastics used by consumers are a remarkably recent invention. The first plastic bags were introduced in the 1950s; the same decade that plastic packaging began gaining in popularity in the United States. This growth has happened so fast that science is still catching up with the change. Plastics pollution research, for instance, is still a very early science．

We put all these plastics into the environment and we still don't really know what the outcomes are going to be. What we do know, though, is disturbing. Ocean plastic is estimated to kill millions of marine animals every year. Nearly 700 species，including endangered ones, are known to have been affected by it. One in three leatherback turtles, which often mistake plastic bags for jellyfish, have been found with plastic in their bellies. Ninety percent of seabirds are now eating plastics on a regular basis. By 2050, that figure is expected to rise to 100 percent．

And it's not just wildlife that is threatened by the plastics in our seas. Humans are consuming plastics through the seafood we eat. I could understand why some people see ocean plastic as a disaster, worth mentioning to the same degree as climate change. But ocean plastic is not as complicated as climate change. There are no ocean trash deniers （否认者）, at least so far. To do something about it, we don't have to remake our planet energy system．

This is not a problem where we don't know what the solution is. We know how to pick up garbage．Anyone can do it．We know how to dispose （处理） of it. We know how to recycle. We can all start by thinking twice before we use plastic products. Things may seem ordinary, like using a reusable bottle or a reusable bag. But when taken collectively, these choices really do make a difference．

【解析】

本文是一篇说明文。短文主要介绍了越来越多的塑料正在污染着海洋。

1.细节理解题。根据第二段中This growth has happened so fast that science is still catching up with the change. Plastics pollution research, for instance, is still a very early science．“这种增长如此之快，以至于科学仍在追赶这种变化。塑料污染的研究,举例来说,仍然是一个非常早期的科学。”可知，塑料污染研究之所以仍然是一门非常早期的科学，是因为塑料流行太快而科学不能赶上来。故选D。

2.推理判断题。根据第三段中Nearly 700 species，including endangered ones, are known to have been affected by it. One in three leatherback turtles, which often mistake plastic bags for jellyfish, have been found with plastic in their bellies. Ninety percent of seabirds are now eating plastics on a regular basis. By 2050, that figure is expected to rise to 100 percent．“近700种,包括濒危的,都受到它的影响。三分之一的棱皮龟腹部都有塑料制品，它们经常把塑料袋误认为水母。现在90%的海鸟定期食用塑料。到2050年,这一数字预计将上升到100%。”可知，在第三段作者通过数据来支持他的建议。故选A。

3.推理判断题。根据第四段中But ocean plastic is not as complicated as climate change.可知，但是海洋塑料污染不像气候变化那么复杂。由此判断出，气候变化并不像海洋污染那么简单。故选B。

4.主旨大意题。通读全文尤其是根据第一段中Researchers recently also found that sea creatures living in the deepest place on Earth, the Mariana Trench，have plastic in their stomachs. Indeed, the oceans are drowning in plastic．可知，研究人员最近还发现，生活在地球最深处---马里亚纳海沟 的海洋生物胃里有塑料。事实上，海洋正在被塑料淹没。所以短文的主旨大意为“海洋里充满了塑料 ”。故选B。
