Psychologically defined， concentration is the process of centering one‘ s attention over a period of time. In practical application， however， concentration is not as simple to deal successfully with as the definition may imply. For this reason， it is helpful to keep the following points in mind.⑴
1.For this reason， it is helpful to keep the following points in mind.
be helpful to …。 对… 很有益；
keep …。 in mind 把… 记在心里；
译文：因此，记住下列几点是很有帮助的。
Your attention span varies
Even with the greatest effort， our span of attention fluctuates. You can demonstrate for yourself this fluctuation of attention. In a quiet room， place a watch so that it can just scarcely be heard. ⑵Listen carefully and notice how the ticking increases in apparent intensity， fades to a point where it cannot be heard， and then increases again.⑶ This phenomenon reveals how our span of attention fluctuates， for the intensity of the ticking is actually constant.

You pay attention to one thing at a time
Evidence to date indicates that you attend to one idea at a time. It is possible for your attention to shift so rapidly that it seems that you attend to several concepts at once.⑷ But apparently this is only anxxx. In high concentration the shift from the focus of attention is of short duration and relatively infrequent.
4.It is possible for your attention to shift so rapidly that it seems that you attend to several concepts at once.

全句意为：你的注意有可能转移得十分迅速，以至于好像你同时能够专心于几个想法。
An illustration of periods of high， moderate， and low attention
High attention has long periods of attending and short distraction periods. In low attention the periods of attending are short and the distraction periods long. In moderate attention there is a mixture of the extremes. Thus it is easy to see that it is highly unlikely that the student who has most of his attention centered on fancying at large will be able to recall even the major points of a lecture.⑸

see 之后是一个由that引导的宾语从句，在 that 引导的宾语从句中， 含有一个who引导的定语从句
Lack of concentration is a symptom， not the cause， of difficulty. When a student says “I can‘t concentrate”， what he is really saying is， “I can’t attend to the task at hand because my distractors are too strong.”
DISTARCTORS ARE OF TWO SORTS -PSYCHOLOGICAL AND PHYSICAL
A distractor is anything which causes attention to vary from a central focal point. In the study situation distractors may be thought of as either psychological or physical in nature. ⑹Both types of distractors must be understood before the student can attempt to remedy his lack of concentration.
In the study situation distractors may be thought of as either psychological or physical in nature.
thought of as 把…看作，认为…
译文：在学习的情况下，干扰物实际上可以被认为是心理的或者是物质的。
Emotions are the most powerful distractors
The angry man forgets the pain of injury， the fearful man finds it difficult to enjoy pleasure and the tense or anxious person may react violently to the smallest of matters.⑺ In the student‘s life there are many psychological pressures and tensions which block effective productivity. The fears about making the grade， the doubts of the friendliness of a friend’s behaviour and the pressures of limited friendliness of a friend‘s behaviour and the pressures of limited finances - these are only a few of the emotional forces which affect the student.
7.The angry man forgets the pain of injury， the fearful man finds it difficult to enjoy pleasure and the tense of anxious person may react violently to the smallest of matters.
Emotional reaction varies greatly from person to person.⑻ Some person gain goal and direction from their tensions and actually do better because of them . Others fall apart under pressure ，while a few people do well despite the pressure.
