The oceans have always served as a sink for carbon dioxide, but the burning of fossil fuels since the beginning of the industrial revolution, especially over the last 40 years, has given them more than they can【S1】______absorb. The result is that the oceans are becoming acid—a change in the【S2】______balance that threatens the oceans’ web of life.
In earth’s history, there have been many【S3】______of acidification, mainly from volcanic eruptions (火山喷发). According to a new research review by pale oceanographers at Columbia University, published in Science, the oceans may be【S4】______acid far faster than at any time in the past 300 million years.
Changing something as【S5】______as the PH of seawater has profound effects. Increased acidity attacks the shells of shellfish and the skeletal foundation of corals (珊瑚), dissolving the calcium carbonate (碳酸钙) they’re made of. Coral reefs are among the most diverse ecosystems on the planet. Ocean acidification【S6】______the corals and every other【S7】______that makes its living on the reefs.
The authors tried to determine which past acidification events【S8】______the best comparison to what is happening now. The closest analogies are disastrous events, often associated with intense volcanic ac tivity resulting in major extinctions. The difference is that those events【S9】______thousands of years. We have acidified the oceans in a matter of decades, with no signs that we have the political will to slow, much less halt, the【S10】______.
A) absolutely I) process
B) animals J) safely
C) changing K) species
D) chemical L) transmitted
E) covered M) threatens
F) episodes N) turning
G) fundamental O) urgent
H) offer [br] 【S4】
选项
答案
N
解析
空格位于系动词之后,由此推断应填入名词或形容词作表语,或者填入动词现在分词表示现在进行时。空格后有形容词acid.由此可判断此处只能填入动词现在分词形式。根据文意,海洋酸化的速度比之前的3亿年间的任何一个时候都快,因此选择turning“变化”。changing也意为“变化”,但该词后面不能接形容词,故排除。
