单选题 Have you ever found your mind a million miles away while someone was making a speech at a meeting? You probably felt sorry and made up your mind to pay attention and never have daydreaming again. Most of us, from earliest school days, have been told that daydreaming is a waste of time.
Early experts in psychology paid no attention to the importance of daydreams or even considered them harmful. At one time daydreaming was thought to be a cause of some mental illness. They did not have a better understanding of daydreams until the late 1980s. Eric Klinger, a professor of psychology, said, "Daydreaming is one of the main ways that we organize our lives, learn from our experience, and plan for our futures ... Daydreams really are a window on the things we fear and the things we long for in life."
Daydreams are usually very simple and direct, quite unlike sleep dreams, which may be hard to understand, it's easier to gain a deep understanding of your life by paying close attention to your daydreams than by examining your sleep dreams carefully. Daydreams help you recognize the difficult situations on your life and find out a possible way of handling them.
Daydreams cannot be predicted; they move off in unexpected directions which may be creative and full of useful ideas. For many famous artists and scientists, daydreams are a main source of creative energy.

单选题 Daydreaming used to be considered ______.

单选题 In what way are daydreams different from sleep dreams?

【正确答案】 A

【答案解析】细节题。见第三段段首Daydreams are usually very simple and direct, quite unlike sleep dreams, which may be hard to understand(白日梦通常简单直接，它们与难以捉摸的睡梦是不同的)。所以，A项“白日梦容易理解”是正确的。

单选题 Professor Eric Klinger believes that ______.

【正确答案】 D

【答案解析】细节题。见第二段第四句Eric Klinger, a professor of psychology, said, "…Daydreams really are a window on the things we fear and the things we long for in life." (心理学教授Eric Klinger说道：白日梦确实是反映我们生活中所恐惧和期待的事物的一扇窗户)。D项最为接近原义，故为正确选择。

单选题 The writer of the passage thinks that ______.

【正确答案】 B

【答案解析】推断题。作者在第三段中指出It's easier to gain a deep understanding of your life by paying close attention to your daydreams than by examining your sleep dreams carefully(密切关注你的白日梦比注意你的睡梦更能使你对自己的生活有深刻的了解)，以此可推断出B项“作者认为白日梦比睡梦更有帮助”是正确答案。

单选题 Which of the following is NOT true according to the passage?

A、 Daydreaming was once regarded as a cause of some mental illness.
B、 Scientists believe that we can know daydreams before having them.
C、 Many well-known artists gained energy of creation from daydreams.
D、 Experts began to have a better understanding of daydreams in the late 1980s.

【正确答案】 B

【答案解析】细节题。A项的“白日梦曾被认为可导致某些精神疾病”在第二段第二句At one time daydreaming…some mental illness 句中有所体现；C选项的“许多知名艺术家从白日梦中获得了创造力”接近于文章最后一句For many…source of creative energy(对许多著名艺术家来说，白日梦是他们创造力的主要源泉)；D项“20世纪80年代晚期起，专家们对白日梦有了更深入的了解”等同于第二段第三句They did not…until the late 1980s。B项“科学家认为我们在做白日梦之前就可了解它们”与文章中提到的“我们可以通过密切关注白日梦更深入地了解生活中的问题”相反，故B项不是文中提到的内容，为本题的正确选择。
