正确答案:

C

答案解析:

【句意】尽管牛顿非常伟大,然而他的许多观点当前正受到怀疑,并且当今的许多科学家正在努力对这些观点进行修正。

【难点】challenge意为“挑战,怀疑”,常用作及物动词。本句中牛顿的观点受到挑战为一个当前已经发生的事实,故采用现在完成时的被动语态。

汉译英;我想不起来哪一个熟人没有手机。今天没有手机的人是奇怪的,这种人才需要解释。我们的所有社会关系都储存在手机的电话本里,可以随时调出使用。古代只有巫师才能拥有这种法宝。

手机刷新了人与人的关系。会议室门口通常贴着一条通告:请与会者关闭手机。可是会议室里的手机铃声仍然响成一片。我们都是普通人,并没有多少重要的事情。尽管如此,我们也不会轻易关掉手机。打开手机象征我们与这个世界的联系。手机反映出我们的"社交饥渴症"。最为常见的是,一个人走着走着突然停下来,眼睛盯着手机屏幕发短信。他不在乎停在马路中央还是厕所旁边。

为什么对于手机来电和短信这么在乎?因为我们迫切渴望与社会保持联系。
