    睡眠在我們的生活中起著非常重要的作用。傳統(tǒng)觀念認為睡眠是人們養(yǎng)精蓄銳的階段,人們在睡眠期間不會有任何思想動態(tài)。然而,一項新的研究表明人們在睡眠期間照樣可以進行語言學(xué)習(xí)。

    Sleeping hours are generally considered unproductive time. But several studies have suggested some learning activity can happen. They found that simple learning through sounds may be possible during sleep.

    Much of the earlier research found that memories developed when people were awake were strengthened during sleep. This supported the idea that information learned while awake is replayed and deeply embedded in the sleeping brain. Therefore, if replay during sleep improves the storage of information that is learned while awake, the storage of new information can also be possible during sleep.

    In order to prove their theory, researchers carried out experiments on a group of young German?speaking men and women. They observed individuals in a controlled environment during brief periods of sleep. They recorded brain activity as pairs of words were played for the study subjects. One word in the pair was a real German word. The other was a made?up foreign word. Each word pair was played four times, with the order of the words changed each time. The word pairs were played at a rhythm that is similar to actual brain activities during deep sleep.

    The goal was to create a lasting memory link between the false word and the German word that individuals could identify when awake. When the subjects woke, they were presented with the false language words—both by sight and sound. They were then asked to guess whether the false word played during sleep represented an object smaller or larger than a shoebox.

    This brain structure is very important for building relational memory during non?sleep periods. Memory was best for word pairs presented during slow?wave peaks during sleep. The study suggests that memory formation in sleep appears to be caused by the same brain structures that support vocabulary learning while awake.

    Difficult Sentence

    The study suggests that memory formation in sleep appears to be caused by the same brain structures that support vocabulary learning while awake.這項研究表明,睡眠期間記憶的形成似乎是由在醒著的時候支持詞匯學(xué)習(xí)的相同的大腦結(jié)構(gòu)引起的。

    【點石成金】appear to do為固定結(jié)構(gòu),意為“似乎要做某事”。that support vocabulary learning while awake為定語從句,修飾先行詞brain structures。本句中的suggest意為“表明”,故后面的賓語從句不用“(should)+動詞原形”的虛擬語氣形式。
