问题     The phenomena known as deja vu has been one of keen interest for scientists, religious and the common man for ages. The idea that one may be experiencing a repeated vision of some sort from the distant past or future is an intriguing concept, although not one easily agreed upon. Indeed, numerous theories exist on the meaning behind those feelings that one has "seen this before," some more scientific than others, of course.
    One common explanation for the phenomena is based on certain religious beliefs. For those that believe in the theory of reincarnation, that our souls are reborn into new bodies on earth after death, it is not a far stretch to believe that some of our memories may remain with our soul during this transition. To proponents of this theory, the feeling of "having seen it before" is simply a leftover memory from one’s past life, coaxed out of hiding by some stimulus in the current one. To them, the feeling of having seen it before means just that: that they have indeed seen it before, although not in the present lifetime.
    Some, however, believe that the phenomena of deja vu is explained most adequately by the concept that humans have extrasensory perception(ESP), the power to be aware of things beyond the grasp of our normal five senses of sight, hearing, touch, smell and taste. To those who believe in ESP, one who has "seen it before" has indeed seen it before, not in a past life, but rather through ESP in the form of a premonition. The phenomena of deja vu, thus, to those who believe in ESP, is proof that humans are capable of seeing the future in some limited ways.
    The theory that has its basis most firmly rooted in science, however, is a much more mundane one. Those who attribute deja vu to entirely natural sources(other than ESP)claim that the experience of feeling that one has "seen it before" is actually the experience of seeing it twice: once with the senses and again with the mind. Proponents of this theory believe that an individual’s senses may at times register stimulus from the outside world such as a sight, smell or taste faster than their brains can process the information. Thus, when the brain finally finishes evaluating the data that the senses have sent, it has two "records" of it—one by the senses and one by the brains, but both equally real, thus the feeling of deja vu.
The main purpose of this text is to______.
选项 A、inform the reader as to what causes the phenomena of deja vu
B、weigh the validity of various theories regarding the basis of deja vu
C、present different theories that explain deja vu for the reader’s consideration
D、argue that deja vu is a contentious issue through the listing of various opposing viewpoints
答案C
解析 属主旨思想题。文章第一段最后一句就是本文的中心：在这些“似曾经历”的感觉所代表的意义背后，存在着众多的理论……；下文都是这些理论的介绍。此外，了解一下本文的结构也有助于找出文章的主题思想：第一段总起全文，说明关于这一问题有无数的理论来解释，接下来的三段各自介绍了一种理论，而且还分析了正反观点，每段最后有总结。看英文结构更明显：1)Indeed，numerous theories exist on…2)One common explanation…For those that believe in the theory…To proponents of this theory…To them…3)Some，however,believe that…To those who believe in ESP…thus…4)The theory that…Those who attribute…Proponents of this theory believethat…Thus…。由此可知，选项C正确。其他选项都与原文意思不符，选项D中的contentious意为“有异议的”。
