31、mories. __2__ We know that, while awake, fresh memories are recorded by reinforcing (加強) connections between brain cells, but the memory processes that take place while we sleep have been unclear. Support is growing for a theory that sleep evolved so that connections between neurons (神經(jīng)元) in the br

33、ons between neurons weaken while sleeping. If Tononi's theory is right, it would explain why, when we miss a night's sleep, we find it harder the next day to concentrate and learn new information—our brains may have smaller room for new experiences.

37、這個論點相呼應的例子是E項，該項中的that指代的就是前面的假設，也就是說，這個假設能夠解釋為什么學生在學習完如果有機會睡一覺，他們會在考試中發(fā)揮更好。 3．F　由下段首句中的代詞he可知，該空中必然包含一個人名，否則he就失去了所指對象，瀏覽各選項，可鎖定F項和G項，但只有F項能與本段的內(nèi)容銜接，也就是說，睡眠會幫助清除記憶，為新記憶騰出空間。按照研究人員Tononi的說法，“睡眠是我們?yōu)閷W習付出的代價”。 4．G　該段首句說“現(xiàn)在我們有最直接的證據(jù)證明他的假設是對的”，那接下來應該是具體描述該證據(jù)。此外，該空后面一句話解釋了實驗的結果和意義。綜合看來，只有G項符合語境，指出了研究團隊、實驗對象及實驗內(nèi)容。 5．B　由最后一段第二句及空格后的“you keep what matters” (你記住要緊的事情)可知B項“這就好像是大腦在保存最重要的記憶”，符合語境。 - 9 -
