问题     Three blind men were exploring an elephant. The first of them, who
happened to reach the leg, described the elephant like something like a tree (1)______
trunk—high and of cylindrical shape.
    The second one grasped the ear and described the elephant as something
like a blanket—flexible, thin, and cover a large surface. The third grasped (2)______
the trunk and therefore shaped an image of a long and flexible pipe-shaped (3)______
object like a hose.
    For a long time they are arguing about the right conception of the elephant. (4)______
    We cognitive scientists are often in the role of those blind re
searchers trying to understand human cognition. Since it is a huge and
complex object of study, each of us approaches to it from a certain (5)______
perspective and studies only a tiny bit of it. Although we do not mis
represent the whole of cognition as the particular object of study, we (6)______
tend to think of mechanisms that could explain the tiny fraction we
have focused. To continue the elephant story, when "trunk specialists" (7)______
observe the fluid that comes out when the trunk is cut, they tend to hy
pothesize it is an olfactory secretion. "Leg specialists" also observe a
fluid coming out when the leg is cut but have a very different hypoth
esis about it—it must be some filling of the leg. The fact this fluid is (8)______
one and the same in all cases (blood) and has the same function can be
discovered only when these scientists come together and consider the
elephant as the whole. They need to explore the interactions between (9)______
varied parts and to postulate general principles and systems. (10)______
(4)

答案are — were
解析 孤立地看这个句子没有任何问题，然而结合前文，发现时态产生了突然的变化，而这个变化是不合理的。这个句子仍然是“盲人摸象”这个故事的一部分，仍然在过去时间。从此题可以看出做改错题时不能忘记把整篇文章作为一个整体来考虑。
