1. Geologists believe that the Bering land bridge, over which human beings are thought to have first entered the Americans, disappeared about 14,000 years ago when massive glaciers melted and caused the sea level to rise several hundred feet worldwide.
(A) are thought to have first entered
(B) were thought first to enter
(C) were thought at first to enter
(D) are thought of as first entering（A）
(E) were thought to first enter
为什么human being are thought 是用现在时？并且后面跟着have entered?

首先这里没有明显的过去时的标志,不能用were,那么用一般时可以理解为是多普遍认知的事情进行描述.D有个问题,如果是对的,这里的entering也应该是enterance吧.其次,句意有问题,人类倍认为是第一次进入,逻辑上有问题啊.
