阅读理解。

     Recently I paid a visit to Harvard University, where there are top class scientists and professors and

the best academic(学术的)system in the world.

     I was pretty shocked when I first stepped onto the campus(校园). Well, it's not even really a campus.

It's more like a district in a small town.

     Harvard's main buildings are from the 18th century. They look very old and simple. You might even

say they're a little old. They don't fit the modern idea of university at all. The buildings are surrounded by

grass and trees, so I felt as if I had walked into a medieval castle(中世纪的城堡). But when I looked

across the street, busy shops and in-fashion students made me feel like I was in the 21st century again.

It creates a strong contrast(对比)and brings a special atmosphere to the school.

     Our tour guide Gary took us around and told us: "You see this grass field in the center of the school?

Here is where they host their graduation ceremony(毕业典礼). They just set up tents and benches and

have a very simple ceremony." Unbelievable! Who would think the most talented students just graduate

on the lawn?

     I saw some students put a blanket on the grass and lie down to read a book. When I listened to the

soft sound of pages turning, along with singing of the birds, I felt very calm. There was no competitive

feeling at all.

     Harvard has the world's first computer in its science center and there are hundreds of high-end

computers too. Its religion and the literature departments are also among the best. It is the perfect mix of

tradition and new technology. It makes Harvard a very attractive place to study in.

     I hope one day I'll attend my dream school - Harvard.

地球上生命的历史也就是生物与它们的环境相互作用的历史。动植物的形体和习性在很大程度上是由环境造成的,而反向作用,即生物对其所在环境的实际影响则相对较小。只有到了20世纪,作为物种之一的人类才获得了足够的力量,有效地改变他所在的世界——人自然。

在过去的四分之一世纪里,这种力量不仅增大到令人不安的程度,而且性质也发生了变化。人类对环境最可怕的破坏,是那些有害甚至致命的物质对空气、土地、河流、海洋造成的污染。在当今对环境的普遍污染中,化学药品和辐射线共同改变着生物的根本性质。喷洒在农田、森林或花园里的化学药品长期留在土壤中,进入活的生物体内,在一种毒害和死亡的连锁反应中从一个生物体传到另一个生物体。有时候,这些化学药品会随着地下溪流神秘地流淌,直到冒出地表,通过空气和阳光的化合作用构成新形式。植物毒死了,牲畜得病了,曾经一度纯净的井水,也给饮用它的人群造成了危害。

适应这些化学药品所需要的时间应该用大自然的尺度来衡量——人的一生太短暂,而它所要求的是若干个世纪。但即使经过漫长的时间,人们能够奇迹般地适应了它们,也无济于事,因为各个实验室还在源源不断地冒㈩新的化学药品,并投入使用。这些药品的数字实在令人震惊:每年有500种新的化学药品需要人和动物的身体以某种方式与之适应。其后果还不容易被我们所预料,因为它完全超出了我们对生物学的理解和经验。

20世纪40年代中期以来,为了杀死老鼠等啮齿动物以及害虫、杂草而研制出来的基本化学药品就超过200种。这些粉末、喷雾液、烟雾剂在农场、花园、森林和家庭中都普遍使用。它们不加选择地杀死任何昆虫,不管它是“好”是“坏”。这种剧毒物质覆盖在叶片表面上,或者滞留在土壤中,能使鸟儿不再歌唱,鱼儿不再遨游。可是,人们使用这些药品,其目的仅仅是消灭屈指可数的几种害虫、杂草或老鼠等。

药物喷洒的发展过程似乎卷入了一个永无终点的螺旋。自从“滴滴涕”被允许民用以后,杀虫剂便______升级。因为有的昆虫已演化出对某一杀虫药具有抗药性的新品种,于是,人们又发明一种更毒的药剂,接着,再发明一种比这种药剂还要毒的药剂。然而,难道有人会相信,可以向地球表面倾泻这么多毒物而又适宜于一些生物生长吗

根据文意,下列对文中的“足够的力量”的理解,正确的一项是()。

A.人类所获得的空前的改变社会环境的力量

B.地球上的生物施加给自然环境的反向作用力

C.环境对地球上生物的作用和地球上生物对环境的反作用

D.人类在20世纪所取得的足以改变自然环境的力量
