　　三、阅读理解

　　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 potentially harming sea life.

　　Montana 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 and 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 colleagues 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 colleagues 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 catastrophic.”

　　1．What can be the best title of the passage?

　　A．Sea Life Facing Danger

　　B．Scientist Researching Seawater

　　C．Oceans Becoming More Acidic

　　D．Climate Change Affecting Seawater

　　2．Which of the following shows the process of the impact of atmospheric CO2 on sea life?

　　a．Sea life is endangered.

　　b．CO2 goes into the surface water.

　　c．The ocean chemistry is affected.

　　d．CO2 decreases the pH and makes the seawater more acidic.

　　e．CO2 levels in the atmosphere go up.

　　A.―→―→―→―→

　　B.―→―→―→―→

　　C.―→―→―→―→

　　D.―→―→―→―→

　　3．Scientist Robert Dore came to the conclusion based on ______.

　　A．his research and analysis

　　B．the expectation of other scientists

　　C．some former theory

　　D．a major cause of climate change

　　4．What does the passage want to tell us most?

　　A．It takes time to make a scientific study.

　　B．Atmospheric CO2 is doing harm to sea life.

　　C．Robert Dore is a committed and serious scientist.

　　D．Measures should be taken to prevent the potential catastrophe.

　　解题导语：在母亲的“胁迫”下，作者逐渐迷恋上了迈克尔·杰克逊的歌声和动作。当他逝世这一噩耗传开后，作者感到无比失落。虽然人们对他的非议早已烟消云散，可是作者依然播放着他的歌曲，在音乐声中缅怀心中的偶像。

　　1．解析：此处是对过去的回忆，叙述的是作者“孩童”时代的事情。另外，第三段中的“my childhood”也是提示。

　　答案：B

　　2．解析：本句提到作者的母亲经常购买迈克尔·杰克逊的音乐专辑，由此可知用sale。on sale 表示“出售，折价销售”。

　　答案：D

　　3．解析：下文提到作者对迈克尔·杰克逊在Thriller中像狼一样的外貌感到无比恐惧，由此可知作者当时不敢观看，所以是作者的母亲“强迫”作者和她一起欣赏。

　　答案：B

　　4．解析：前半句叙述的是对他的外貌的恐惧，后半句描写的是对他的声音以及动作的入迷，所以选A项，表示的是让步关系。

　　答案：C

　　6．解析：上文提到作者迷恋他的声音和动作，所以自己开始慢慢收集他的专辑。build表示“创建，建立”。

　　答案：C

　　9．解析：听到迈克尔·杰克逊在6月份突然去世的消息，作者感觉自己童年时代的一个重要的组成部分也随之“消亡”。

　　答案：A

　　10．解析：上文中提到作者痴迷于他的优美的声音和娴熟的动作，由此可知作者一直非常喜欢他的音乐和舞步。

　　答案：A

　　12．解析：结合上下文可知他“曾经”是一个才华横溢精力充沛的表演者，后来成为一个总是戴着防护物以遮蔽阳光的可怜人物。

　　15．解析：迈克尔·杰克逊逝世后，有关他的谣言都被抛在一边，以纪念已故的“流行音乐之王”。throw aside“把……扔在一边”。set aside表示“把……放在一边(以备后用)”，语义不恰当。

　　答案：A

　　16．解析：由下文那些曾经认为他是恋童狂、怪人的人们如今认为他是一个完美的人，是世上最伟大的音乐家，是多么荒谬，可知作者对此感到十分“气愤”。

　　答案：B

　　17．解析：此处是“consider＋宾语＋宾补”的用法。

　　答案：A

　　19．解析：既然是在悼念一个人的死亡，应该是“无声地”进行。尽管有些人前后不一的行为很让人沮丧，“我”还是默默地哀悼杰克逊。此处用silently也与上文众人的前后不一的喧嚣形成对比。后三项分别表示“安静地”“镇静地”“深深地”，语义都不太合适。

　　答案：A

　　答案：A
