Dreams are notoriously difficult to recall. In fact, if a dream ends before we wake up, we will not remember it.(19)The processes that allow us to create long-term memories largely lie inactive while we sleep, which is why most dreams are forgotten shortly after waking. As the brain awakens, it starts to turn on processes needed for long-term storage. Thus, if we wake straight out of a dream, we have a greater chance of remembering it. A study showed that people who have more brain-wave activity in their brain after waking from rapid-eye-movement sleep have better dream recall. The emotional content and logical consistency of a dream also affect how much of our dreams we remember.(20)One study found that less coherent dreams were harder to recall than the ones with strongly-felt content and organized plot lines. The dreams we are likeliest to retain—nightmares and other vivid, emotional dreams—are accompanied by greater arousal of brain and body and are therefore more likely to wake us up. Certain techniques can help increase dream recall. Anything that captures our attention immediately after waking interferes with dream recall. So just as you are falling asleep, keep reminding yourself that you want to remember your dreams. Let it be your last thought as you are drifting off. Keep a notepad and pen by the bed. When you first wake up, do not jump up or turn your attention to anything.(21)Even if you do not think you can remember a dream, take just a minute to see if there is any feeling or image you can describe. Following these simple steps may cause an entire dream to come flooding back.
19. Why do people forget most dreams soon after waking?
20. What dreams are harder to recall?
21. What should we do after waking up to recall dreams?
选项
A、Most dreams are too complicated for people to remember.
B、The brain cannot hold long-term memories during sleep.
C、Most people nowadays are suffering from memory loss.
D、Human brain cannot hold too many dreams at a time.
答案
B
解析
原因目的题。本题问的是为什么人们醒来后会忘记大多数的梦。短文开头提到,当我们睡觉的时候,能够帮我们创造长期记忆的过程大多都处于不活跃的状态,这就解释了为什么我们醒后会很快忘掉大多数的梦。由此可知,人们之所以会在醒来后忘记大多数的梦是因为人在睡觉时,大脑无法储存长期记忆。
