阅读理解。

     Today just as technology changed the face of industry, farmers have undergone an "agricultural

revolution". On the farm of today, machines provide all the power.

     One of the most important benefits will be the farm computer. A few forward-looking farmers

are already using computers to help them run their farms more efficiently. The computers help them

keep more accurate records so they can make better decisions on what crops to plant, how much

livestock to buy, when to sell their products, and how much profit they can expect. Many computer

companies have been developing special computer programs just for farmers. Programs are being

written for hog(猪) producers, grain farmers, potato farmers, and dairy farmers. In the future, farmers

will be able to purchase computer programs made to their needs. Because of the growing importance

of computers on the farm, students at agricultural colleges are required to take computer classes in

addition to their normal agricultural courses. There can be no doubt that farmers will rely on computers

even more in the future. While the old-time farm depended on horse power, and modern farms

depend on machine power, farms of the future will depend on computer power.

     Another technological advance which is still in the experimental stage is the robot, a real "mechanized

hired hand" that will be able to move and, in some ways, think like a human being. Unlike farmers of

the present, farmers of the future will find that many day-to-day tasks will be done for them. Scientists

are now developing robots that will be able to shear(修剪) sheep, drive tractors, and harvest fruit.

Even complex jobs will be done by robots. For example, in order to milk their cows, farmers must

first drive them into the special barn(畜棚), then connect them to the milking machines, watch the

machines, and disconnect them when they are finished. In the future, this will all be done by robots.

In addition, when the milking is completed, the robots will automatically check to make sure that

the milk is pure. The complete mobilization of the farm is far in the future, but engineers expect that

some robots will be used before long.

阅读以下文字，回答下列题。
板块结构理论认为，地球的外壳分为若干部分或称为板块，这些板块始终处于相对运动之中。板块的不断移动，使断层——穿过岩层的地质裂缝——的应力不断增加，造成岩层的略微变形，最终断裂而产生断层地震。这时变形的岩层会弹回来，像一根拉长的橡皮带绷断后一样。其后，断层的各边都移动，岩层的弹性畸变也消失了。
地震前断层周围的应力会增大，这个概念促使人们想到许多检测这种地震警报的方法，科学家可以通过重新测量绘制地图时使用的三角测量点的网络来测出微小的变形。他们也可以在适当的地方安放应变仪或倾斜计这类仪器。由于变形能改变蓄水能力(或者说通过使细小裂缝开启或闭合而改变岩层的孔隙度)，因此孔隙内的水位也可以提供有用的信息。现在卫星已可以用来对地球表面的点进行测量，其精度可达几厘米，所以现在的许多测量点都可以从空间重新测绘。所有这些方法在可能发生地震时都会有所显示。
当一个断层的不同部分活动的方式互不相同时，如果断层的一个部分经常有中度地震，而它的一个邻近地带在历史记载中却没有发生过地震，那么断层的这个平静地带(称作地震空白区)就可能是将发生地震的地方。
但是断层的所有部分不都是照这种方式活动的。有些活断层从来没有产生过引起人们注意的地震。由于许多岩层极其缓慢变形的共同作用的结果，它们在不断地滑动，其速度与板块的移动相一致，这种活动方式所产生的地震很轻微，不借助灵敏的地震仪，是不会觉察到的，这个过程叫做蠕动。正在蠕动的断层不会发生严重的地震灾害，除非蠕动停止。通过对蠕动的断层和地震空白区的多年监视，研究人员能够确定出将来最可能发生地震的地区。

“岩层的弹性畸变”消失的原因是( )。

A．地震消除了积存在板块中的应力
B．断裂的岩层不断向各边移动
C．地震使积存在板块中的应力增加
D．板块的不断移动使岩层断裂
