Scientists visiting tiny Henderson Island in the South Pacific recently made an alarming discovery. 1. ____FThey calculated there were 38 million pieces of plastic. "This is not an issue to ignore. We need to do something now to protect the sea," said one scientist.
Plastic waste in the sea has long been known about, but only now are we discovering the true extent (程度) of the problem. Plastic takes hundreds of years to decompose (降解), so all the plastic ever produced still exists somewhere. Around 95% of plastics made are not recycled, and large amounts enter the sea. Currents (洋流) collect this waste in large circular systems called "gyers". 2. ____G
The problem gets worse as plastic breaks down into very small pieces, or "micro plastic". 3. ____BHumans also eat these fish, and micro plastic has even been found in tap water around the world. The plastic on Henderson Island accounts for just 2 seconds' worth of global annual plastic production. That production will be three times by 2050.
4. ____EWhile diving in Greece, young Boyan Slat noticed there was more plastic waste than fish. He decided right then to dedicate his life to solving this problem. Boyan thought, why move through the sea when the sea can move through you? So he started The Ocean Cleanup project, which places very long floating barriers in the Pacific. Currents then concentrate the waste naturally so it can be collected and recycled. He hopes to reduce the patch by 50% in just five years.
"Sea plastic is a symbol of the negative effects of our lifestyle and technology," he says. "5. ____DProtecting the sea from plastic is a good place to start!"
A. It goes unnoticed and finds its way to human bodies.
B. This is eaten by fish and leads to massive species loss.
C. To work with the currents would help collect the waste.
D. Our aim should be to create a new lifestyle for this century.
E. However, there are some young minds working to clean up the sea for future generations.
F. Although remote and previously untouched by humans, the island was covered in plastic waste.
G. One of the largest is in the Pacific Ocean, an area now known as the "Great Pacific Garbage Patch".

答案： 语篇导读 本文是一篇说明文。文章主要介绍科学家们发现了海洋中的塑料垃圾已经非常严重,人们需要做些什么来保护海洋。 1.F 根据上文可知,科学家们到了一个岛上并有了惊人的发现。而下文"They calculated there were 38 million pieces of plastic."则告诉我们塑料的总数。F项承上启下,与上下文内容一致。故选F。 2.G 根据空前一句可知,在海洋中,环流在收集这些废物。G项与上文内容一致。故选G。 3.B 根据空前一句可知,微塑料会更糟糕。而空后"Humans also eat these fish, and micro plastic has even been found in tap water around the world."则暗示空处指的是鱼类会食用微塑料。B项承上启下,与本段内容一致。故选B。 4.E 根据空后两句可知,本段主要讲述的是有人正在清理海洋塑料垃圾。E项与下文内容一致。故选E。 →空处为段首句，为本段主要内容 5.D 根据下文可知,空处指的应该是一个很好的憧憬,而保护海洋免受塑料污染是这一美好未来的良好开端。D项与下文内容一致。故选D。
