By the end f the century, if nt sner, the wrld's ceans will be bluer and greener thanks t a warming climate, accrding t a new study.
At the heart f the phenmenn lie tiny marine micrrganisms (海洋微生物) called phytplanktn. Because f the way light reflects ff the rganisms, these phytplanktn create clurful patterns at the cean surface. Ocean clur varies frm green t blue, depending n the type and cncentratin f phytplanktn. Climate change will fuel the grwth f phytplanktn in sme areas, while reducing it in ther spts, leading t changes in the cean's appearance.
Phytplanktn live at the cean surface, where they pull carbn dixide (二氧化碳) int the cean while giving ff xygen. When these rganisms die, they bury carbn in the deep cean, an imprtant prcess that helps t regulate the glbal climate. But phytplanktn are vulnerable t the cean's warming trend. Warming changes key characteristics f the cean and can affect phytplanktn grwth, since they need nt nly sunlight and carbn dixide t grw, but als nutrients.
Stephanie Dutkiewicz, a scientist in MIT's Center fr Glbal Change Science, built a climate mdel that prjects changes t the ceans thrughut the century. In a wrld that warms up by 3℃, it fund that multiple changes t the clur f the ceans wuld ccur. The mdel prjects that currently blue areas with little phytplanktn culd becme even bluer. But in sme waters, such as thse f the Arctic, a warming will make cnditins riper fr phytplanktn, and these areas will turn greener. "Nt nly are the quantities f phytplanktn in the cean changing," she said, "but the type f phytplanktn is changing."
And why des that matter? Phytplanktn are the base f the fd web. If certain kinds begin t disappear frm the cean, Dutkiewicz said, "it will change the type f fish that will be able t survive." Thse kinds f changes culd affect the fd chain.
Whatever clur changes the cean experiences in the cining decades will prbably be t gradual and unnticeable, but they culd mean significant changes. "It'll be a while befre we can statistically shw that the changes are happening because f climate change," Dutkiewicz said, "but the change in the clur f the cean will be ne f the early warning signals that we really have changed ur planet."
（1） What are the first tw paragraphs mainly abut?
A . The varius patterns at the cean surface.
B . The cause f the changes in cean clur.
C . The way light reflects ff marine rganisms.
D . The effrts t fuel the grwth f phytplanktn.
（2） What des the underlined wrd "vulnerable" in Paragraph 3 prbably mean?
A . Sensitive. B . Beneficial. C . Significant. D . Unnticeable.
（3） What can we learn frm the passage?
A . Phytplanktn play a declining rle in the marine ecsystem.
B . Dutkiewicz's mdel aims t prject phytplanktn changes.
C . Phytplanktn have been used t cntrl glbal climate.
D . Oceans with mre phytplanktn may appear greener.
（4） What is the main purpse f the passage?
A . T assess the cnsequences f cean clur changes.
B . T analyse the cmpsitin f the cean fd chain.
C . T explain the effects f climate change n ceans.
D . T intrduce a new methd t study phytplanktn.
