UNIT 3 SEA EXPLORATION
Ⅰ.阅读理解
The amount of plastic pollution in the oceans is rapidly increasing.This is problematic, as at least 700 species of sea animals may mistake it for a tasty snack.While we know that some species seem to eat plastic because it looks like jellyfish or some other food sources, less research has been carried out into what plastic smells like to marine animals.
But now, a study from the University of North Carolina has found that the coating of algae that naturally builds up on ocean plastics causes the rubbish to give off the scent of food.
The researchers took 15 loggerhead turtles, each around five months old, and placed them in a laboratory tank.They then piped in clean water, clean plastic, turtle food, and plastic that had been immersed in the marine environment for five weeks.
The turtles showed no reaction to the smell of clean water or clean plastic.But when they were exposed to the smell of ocean-soaked plastic or turtle food, they exhibited food-seeking behaviors like reaching their noses out of the water or showing increasing activities.
“This finding is the first demonstration that the smell of ocean plastics causes animals to eat them,” said Dr.Kenneth J.Lohmann, who took part in the study. “It's common to find loggerhead turtles with their digestive systems fully or partially blocked because they've eaten plastic materials.There are also increasing reports of sea turtles that have become ill and stranded on the beach due to their ingestion of plastic.”
According to the researchers, areas of the ocean with dense concentrations of plastic may trick turtles and other animals into thinking that there is an abundant food source. “Once these plastics are in the ocean, we don't have a good way to remove them or prevent them from smelling like food.” said Lohmann.

“Preparation is vital to surviving natural disasters.” says Thomas M.Kostigen, the author of a new book called the Extreme Weather Survival Guide.We asked him about his new book.

The oceans can absorb 93 percent of the heat trapped by the greenhouse gases which humans release into the atmosphere.And the other 7 percent 5. (absorb) by the air, land and ice caps, according to an 6. (analyse).
“If the ocean wasn't absorbing as much heat, the surface of the land would heat up much 7. (fast) than it is right now,” said professor Malin L.Pinsky at Rutgers University in the US.“In fact, the ocean is saving us from rapid warming right now.”
However, the ocean itself, as Discover magazine noted, is heating up 40 percent faster on average than the United Nations 8. (believe) five years ago.That means if the ocean temperatures increase 9. this speed, the high water temperatures “will kill off marine ecosystems, raise sea levels and make 10.

语篇类型:新闻报道 主题语境:人与自然——环境保护
语篇导读:海洋在减缓全球变暖中起着重要作用,但海洋本身过快的平均升温速度将会带来一些破坏性的影响。
1.答案 Seen
解析 考查非谓语动词。句子主语the Earth与see之间是逻辑上的动宾关系,故用过去分词形式。位于句首的单词首字母需大写。
2.答案 slowing
