阅读下面短文,回答下 * * 道题。
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——大自然。
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出新的化学药品,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,杀虫剂便逐步升级。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切生物生长吗

下列分析符合原文意思的一项是______。

A.动植物的形体和习性是由环境造成的

B.经过足够长的时间,人们可以适应所有的化学药品

C.即使人和动物能适应那些化学药品,我们也不知道他们的身体会出现什么变化

D.每年有超过200种化学药品研制出来用于杀死老鼠等啮齿动物以及害虫、杂草

答案

参考答案:C

解析: A项与原文“很大程度上”不符。B项与原文意思不符,见第三段内容。C项正确。D项原文是“40年代中期以来”,而不是“每年”。

Time was running out, and Mark Dickinson wasn't sure whether he'd get to see his dying 2-year-old grandson one last time. A long line at Los Angeles International Airport's security checkpoint had kept him from getting to his gate on time.

His grandson Caden would be taken off life support in a matter of hours in Denver, Colorado, with or without his grandfather's presence, according to CNN affiliate KABC.

“I was kind of panicking because I was running late, and I really thought I wasn't going to make the flight,” Dickinson told KABC.

That's when a pilot from Southwest Airlines stepped up and held the flight at the gate until Dickinson arrived. The pilot was standing by the air bridge waiting for him when Dickinson arrived in socks, so rushed that he just grabbed his shoes at security and ran through the terminal.

“I told him, ‘Thank you so much. I can't tell you how much I appreciated that.’ And he said, ‘No problem. They can't leave without me anyway,’”Dickinson told KABC.

Authorities say Dickinson's grandson, Caden Rodgers, suffered a head injury after his mother's boyfriend threw him across the room. The boyfriend reportedly told police he was drunk and high on marijuana(大麻) at the time. The child later died and the boyfriend has been charged with first-degree murder, according to the Aurora Sentinel.

Thanks to the pilot, Dickinson made it to Colorado in time to say goodbye to his grandson. Most airlines would punish any staff member who holds up a flight, according to consumer advocate Christopher Elliott, who broke the story of the sympathetic pilot on his blog. However, a Southwest spokeswoman said the pilot's actions were praiseworthy.

“You can't hold a plane for every late customer, but I think we would all agree that these were extenuating(可以原谅的) circumstances and the pilot absolutely made the right decision,” Southwest spokeswoman Marilee McInnis said. “I don't think you could ask for a better example of great service for our customers.”
