英语六级真题，既是检测语言能力的标准尺，也是拓宽知识领域、视野的窗口。每一次的模拟练习，都是对自我能力的一次挑战与提升。以下，我们将以一篇关于“联觉的科学”的文章为例，进行英语六级真题模拟练习。

英文原文

Synesthesia, a neurological phenomenon where stimulation of one sensory modality automatically triggers an involuntary experience in another modality, has fascinated scientists for centuries. Individuals with synesthesia, known as synesthetes, may experience colors when hearing music, or taste flavors when seeing certain shapes.

联觉是一种神经现象，其中一个感官的刺激会自动触发另一个感官的不自主体验，几个世纪以来一直吸引着科学家们的注意。具有联觉的人被称为联觉者，他们可能在听到音乐时看到颜色，或在看到某些形状时尝到味道。

Recent research has shed light on the neurological basis of synesthesia, suggesting that it may arise from increased connectivity or cross-talk between different regions of the brain. For instance, in grapheme-color synesthesia, where letters and numbers evoke specific colors, neuroimaging studies have revealed heightened activity in the color-processing areas of the brain when synesthetes view written symbols.

最近的研究揭示了联觉的神经基础，表明它可能源于大脑不同区域之间增加的连通性或交叉对话。例如，在字形-颜色联觉中，字母和数字会引发特定的颜色，神经成像研究表明，当联觉者看到书写符号时，大脑的颜色处理区域活动增强。

问题

1.What is synesthesia, according to the passage?

A. A disorder that affects all senses simultaneously.

B. A voluntary experience triggered by sensory stimulation.

C. A neurological phenomenon where one sensory experience triggers another involuntarily.

D. An ability to control sensory perceptions at will.

2.Which of the following is a characteristic of grapheme-color synesthesia?

A. Letters and numbers evoke specific smells.

B. Synesthetes see shapes when tasting food.

C. Synesthetes hear sounds when looking at colors.

D. Letters and numbers evoke specific colors.

3.What does neuroimaging research suggest about the neurological basis of synesthesia?

A. It arises from decreased connectivity between brain regions.

B. It is caused by a malfunction in the sensory organs.

C. It is a learned behavior rather than an innate trait.

D. It may result from increased connectivity or cross-talk between different brain regions.

答案解析

1.答案：C

解析：文章将联觉定义为一种神经现象，其中一个感官的刺激会自动触发另一个感官的不自主体验。这与选项C“一种神经现象，其中一个感官体验不由自主地触发另一个感官体验”相吻合。

2.答案：D

解析：文章中提到字形-颜色联觉是字母和数字会引发特定的颜色。这与选项D“字母和数字引发特定的颜色”相符。其他选项（A、B、C）均未在文章中提及为字形-颜色联觉的特点。

3.答案：D

解析：文章指出，最近的研究揭示了联觉的神经基础，表明它可能源于大脑不同区域之间增加的连通性或交叉对话，这得到了神经成像研究的支持。因此，选项D“它可能源于大脑不同区域之间增加的连通性或交叉对话”是正确的。其他选项（A、B、C）均未在文章中提及为神经成像研究所支持的联觉神经基础的观点。

以上就是英语六级真题题型：联觉的科学文章示例，在英语六级备考中，需要保持持续的学习和练习，不断提高自己的英语能力。
