1、2011年职称英语等级考试真题（理工类A级）学派网职称英语团队原创翻译0 第2部分：阅读判断（第1622题，每题1分，共7分）下面的短文后列出了7个句子，请根据短文的内容对每个句子做出判断；如果该句提供的是正确信息，请选择A；如果该句提供的是错误信息，请选择B；如果该句的信息文中没有提及，请选择C。Earth Rocks onMost of the time, the ground feels solid beneath our feet. Thats comforting. But its also misleading because theres actually a lot going
2、 on underground. Masses of land (called plates) slip, slide, and bump against each other, slowly changing the shape of continents and oceans over millions and billions of years.Scientists know that Earth formed about 4.5 billion years ago. They also know that our planet was hot at first. As it coole
3、d, its outermost layer, called the crust（地壳）, eventually formed moving plates. Exactly when this shift happened, however, is an open question.Now, an international group of researchers has an answer. Theyve found new evidence suggesting that Earths crust started shifting at least 3. 8 billion years
4、ago. The new estimate is 1.3 billion years earlier than previous ones.Not long before 3. 8 billion years ago, lots of asteroids（小行星）were hitting Earth, keeping its crust in a hot, melted state. After the hard crust formed, much of it sank at various times into the planets hot insides. There, it melt
5、ed before returning to the surface.In some places, however, the crust never sank. One of the oldest such places is in Greenland, in an area called the Isua supracrustal（上地壳）belt. The rocky crust there is between 3.7 and 3.8 billion years old. The belt was once part of the seafloor, but now it is exp
6、osed to air.The researchers recently took a close look at the Isua supracrustal belt. They noticed long, parallel cracks in the rock that have been filled in with a type of volcanic rock.To explain this structure, the scientists propose that tension in the crust caused the seafloor to crack open lon
7、g ago. Hot, liquid rock, called magma（岩浆）flowed up slowly from deep inside Earth to fill the cracks. Finally, the whole area cooled, forming what we see today.That explanation, plus chemical clues inside the rock, suggests that the Isua supracrustal belt was once part of a plate under the ocean, beg
8、inning around 3.8 billion years ago.16The ground beneath our feet is indeed still.地球在摇晃绝大多数时候，我们感觉脚下的土地很坚实。这让人感到很安慰。但是这也让人产生误解，因为实际上地底下正在发生着很多事情。大块的地面（称为板块）滑动并互相撞击，在几百年到数十亿年间慢慢改变陆地以及海洋的面貌。科学家知道地球是在大约45亿年前形成的。他们也知道我们的地球起初是很热的。随着地球慢慢冷却，它最外面的一层，称作地壳，最终演变成运动的板块。然而这一转变确切是在什么时候发生的还不得而知。现在，一个国际研究小组有了答案。他们发
9、现新的证据，证据表明地球的地壳是在至少38亿年前开始改变的。这个新的预计比之前的预计早了13亿年。在38亿年的不久之前，很多小行星撞击地球，地球的地壳温度极高，处于溶解状态。在硬地壳形成之后，大部分都沉入了地球滚烫的内部。沉入地球内部后，还没来得及返回地表就被融化了。然而在有些地方，地壳从来不下沉。其中最悠久的一个地方就是格陵兰，它位于叫做Isua上地壳带。那里的岩石地壳有着37亿年到38亿年的历史。这一地带以前是海底，现在浮出水面。研究人员最近仔细研究了Isua上地壳地带。他们注意到了岩石里一条很长的平行裂口现在已经被一种火山石填满。为了解释这种结构，科学家提出是地壳的张力导致了地表很久之前
10、裂开。滚烫的液体岩石，称为岩浆，慢慢的从地球的内部流动，填充了裂缝。最终，整个区域都冷却下来，形成了今天我们看到的场景。这一解释，加上岩石内部的化学线索，表明Isua上地壳地带曾经是位于海洋下面的板块，开始于大约38亿年前。1 第3部分：概括大意和完成句子（第2330题，每题1分，共8分）下面的短文后有2项测试任务：（1）第23 26题要求从所给的6个选项中为指定段落每段选择1个小标题；（2）第27 30题要求从所给的6个选项中为每个句子确定一个最佳选项。The iPad1The iPad is a tablet computer（平板电脑）designed and developed by
