Ⅲ.阅读理解
阅读下面的文章，从题中所给的A、B、C、D四个选项中选出最佳答案。
(2010年3月济南市高考模拟考试)
Rising levels of carbon dioxide in the atmosphere are a major cause of climate change, and now a new study has confirmed that atmospheric CO2 is also affecting the ocean chemistry and potenitally harming sea life.
Montans State University scientist Robert Dore has been researching the water in the Pacific Ocean for almost two decades.
“We've been going to the same spot in the Pacific Ocean, and we try to characterize long­term change in the open ocean environment. And one of the key things that we measure is CO2 levels. And we've been able to record this increasing quantity of atmospheric CO2 into the ocean.”
Scientists expected that as atmospheric CO2 increased, more and more of the carbon dioxide would be absorbed into the ocean, affecting the chemical balance of the sea water with a potentially harmful impact on shellfish and coral in particular.
“As carbon dioxide dissolves(溶解)in the water or seawater in this case, it forms a weak acid, carbonic acid，”“Dore explains.”And therefore, as the concentration of CO2 in the atmosphere goes up and that exchanges with the surface seawater, it drives the pH down, and makes it more acidic.”
The seawater Dore and his collegues have analyzed confirms what the theory predicts.
The effect was particularly striking at about 250 meters down, and again at 500 meters. Dore and his collegues came up with two possible explanations. It could be that surface water picked up CO2 and then moved to those depths. Or there could be a biological explanation.
“It's important to realize that the oceans are really becoming acidic. And it could have negative impacts on a whole variety of sea life from fish to coral. It's potentially catastrohpic.”
文章大意：空气中二氧化碳含量增加是气候变化的主要原因，也影响到海水的化学构成，伤害到海洋生物。

沁园春·雪 <毛泽东>
北国风光，千里冰封，万里雪飘。
望长城内外，惟余莽莽；
大河上下，顿失滔滔。
山舞银蛇，原驰蜡象，
欲与天公试比高。
须晴日，看红装素裹，分外妖娆。
江山如此多娇，引无数英雄竞折腰。
惜秦皇汉武，略输文采；
唐宗宋祖，稍逊风骚。
一代天骄，成吉思汗，
只识弯弓射大雕。
俱往矣，数风流人物，还看今朝。
