Let Your Mind Wander
Until recently daydreaming was generally considered either a waste of time or a symptom of neurotic tendencies， and habitual daydreaming was regarded as evidence of maladjustment or an escape from life‘s realities and responsibilities. It was believed that habitual daydreaming would eventually distance people from society and reduce their effectiveness in coping with real problems. At its best， daydreaming was considered a compensatory substitute for the real things in life.①
1.句中as its best 是一個詞組，意思是“好也不過”；daydreaming 是動名詞，在句中作主語；a compensatory… in life 作was considered 的主語補(bǔ)足語。
本句意思是：白日做夢好也不過被認(rèn)為是對生活中實(shí)際事物的一種補(bǔ)償性的替代。
As with anything carried to excess， daydreaming can be harmful. There are always those who would substitute fantasy lives for the rewards of real activity. But such extremes are relatively rare， and there is a growing body of evidence to support the fact that most people suffer from a lack of daydreaming rather than an excess of it. ②
2.本句中由and連接的兩個并列句；該句中to 引起的不定式結(jié)構(gòu)一直到句尾，作evidence 的后置定語；在這一結(jié)構(gòu)中，the fact 后又接由that 引起的同位語從句。本句意思：“但是這類極端的情況較為罕見，愈來愈多的證據(jù)卻支持這樣一種現(xiàn)象，即大部分人受白日做夢過少而不是過多之苦?！?BR> We are now beginning to learn how valuable it really is and that when individuals are completely prevented from daydreaming， their emotional balance can be disturbed.③
3.該句中的how 和that 引起一個名詞性從句作動詞learn 的賓語。在that 引起的從句中，when 又引導(dǎo)一個從句作狀語。本句意思：“現(xiàn)在我們開始了解，白日做夢如何真有價值。并且人如果白日完全不做夢，他們的情緒平衡會被打亂?！?BR> Not only are they less able to deal with the pressures of day-to-day existence， but also their self-control and self-direction become endangered.④
4.本句是由not only 和but also 連接的兩個并列分句?！皀ot only ”否定詞放在句首，因此句子要倒裝。本句意思：“不僅他們應(yīng)付每日生活的壓力的能力會變差，他們的自我控制和自我導(dǎo)向能力也會受到損害。”
Recent research indicates that daydreaming is part of daily life and that a certain amount each day is essential for maintaining equilibrium.⑤
