特别广播英语第 165 课：Controlling Your Concentration 控制你的注意力-2

This phenomenon reveals how our span of attention fluctuates, for the intensity of the ticking is actually constant. 这种现象揭示了我们注意力范围是如何波动的，因为嘀哒声的强度实际上并无变化。

You pay attention to one thing at a time 你在同一时刻注意一件事情

Evidence to date indicates that you attend to one idea at a time. 至今为止的资料表明，在同一时刻你只能注意到一个念头。

It is possible for your attention to shift so rapidly that it seems that you attend to several concepts at once. 你的注意力可能转移得很快，似乎能立刻注意到几个概念。

But apparently this is only an illusion. In high concentration the shift from the focus of attention is of short duration and relatively infrequent. 但显然这只是一个错觉。在注意力集中时，注意力的焦点转移是在很短时间内，而且比较而言是很少发生的。

An illustration of periods of high, moderate, and low attention 高度、适度、低注意力的说明

High attention has long periods of attending and short distraction periods. 高度注意有较强的注意期和很短的注意力分散期。

In low attention the periods of attending are short and the distraction periods long. 在低注意力下，注意到短期而注意力分散期长。

In moderate attention there is a mixture of the extremes. 适度注意力融合了两种极端。
