Question

【題目】 In your dreams, you may clearly see something or hear someone talking. But what about smells? Can you ever remember smells from your dreams?

A study published in 1896 looked at different sensory (感官的) experiences in dreams. It found visual (視覺的) experience ______ controls one’s dreams. It takes up about 85%, while auditory (聽覺的) makes up 69%, and smell only 7%.

But why? Now scientists have possible reasons based on what is known about the brain.

In our brain, there is a special part called the cerebral cortex (大腦皮層). It is linked to our feelings. As much as two-thirds of the cerebral cortex works in vision (視力). So vision

______ often in dreams. Auditory is closely tied to language, and language is processed entirely in the cerebral cortex. Smell, ______, has little to do with the cerebral cortex. It connects directly into the memory and emotional systems. That’s why a smell can bring back a memory.

Another ______ is that perhaps smell is not easily affected (影響) by our imagination. For example, close your eyes and imagine your favorite dish. What do you get? It is easy to think about what it looks like. But it is not as easy to imagine its smell.

Vision and auditory is a complex (復(fù)雜的) process inside the brain. But smell is a direct measurement (衡量) of the chemicals in the air. There is ______ imagination involved in smell. Therefore, smell might not be much affected by the brain activity during dreaming.

It is ______ to taste and touch. That is why you don’t often have the experience of taste and touch in your dreams.

【1】C

【2】B

【3】D

【4】A

【5】B

【6】D

【解析】

本文是說明文。分析了人們夢中很少出現(xiàn)嗅覺的原因。

【1】

句意：它發(fā)現(xiàn)視覺體驗(yàn)主要控制著人的夢境。
hardly 幾乎不；firstly 首先；mainly 主要地；completely 完全地；根據(jù)“It takes up about 85%, while auditory (聽覺的) makes up 69%, and smell only 7%.”可知視覺是占百分之八十五，是占主要作用，用mainly。故選C。

【2】

句意：所以視覺經(jīng)常出現(xiàn)在夢中。
fails 失��；appears 出現(xiàn)；呈現(xiàn)；changes 改變；enters 通過；根據(jù)“As much as two-thirds of the cerebral cortex works in vision”可知大腦皮層主要是視覺，因此它經(jīng)常出現(xiàn)在夢中，用appears。故選B

【3】

句意：另一方面，嗅覺與大腦皮層幾乎沒有關(guān)系。
of course 當(dāng)然；for the first time 第一次；after all 畢竟；on the other hand 另一方面；根據(jù)“But why？”和“Auditory is closely tied to language, and language is processed entirely in the cerebral cortex.”可知這一段是解釋夢里各種情況的原因，解釋到和視覺聽覺有關(guān)，而和嗅覺關(guān)系不大，因此是講到兩個不同的方面，故用on the other hand。故選D。

【4】

句意：另一種可能是氣味不容易受到我們想象的影響。
possibility 可能性；advantage 優(yōu)點(diǎn)；fact 事實(shí)；challenge 挑戰(zhàn)；根據(jù)“In our brain, there is a special part called the cerebral cortex (大腦皮層).”和“Another…”可知第四段是解釋夢境的原因，因此第五段是解釋夢境原因的另一種可能，用possibility。故選A。

【5】

句意：很少有想象力參與氣味。
better 更好；less 更少；more 更多；worse 更糟；根據(jù)“smell is not easily affected (影響) by our imagination.”可知視覺和聽覺能和想象力有密切聯(lián)系，而氣味卻沒什么影響，故用less。故選B。

【6】

句意：它與味覺和觸覺相似。
kind 仁慈的；used 可用的；thankful 感激的；similar 相似的；根據(jù)“That is why you don’t often have the experience of taste and touch in your dreams.”可知味覺和觸覺也不怎么影響夢，因?yàn)樗麄兒托嵊X相似，用similar。故選D。
