【解析】

試題分析：健康對我們的生活質(zhì)量至關(guān)重要。保持充足的睡眠是青少年學(xué)習(xí)成績提高的保證。國家愛睡眠基金會建議青少年要保持9個小時的睡眠時間。調(diào)查顯示，絕大多數(shù)青少年缺少睡眠。研究表明青少年睡眠九個半小時很少有遲到及健康問題。為什么不能采取措施來幫助青少年提高睡眠時間呢？

【1】句意：然而八點之前就開始上課。依據(jù)上下文可知，學(xué)生必須在六點半起床上學(xué)。因為學(xué)校在八點之前就開始上課。故答案為classes。

【2】句意：對于青少年來說，這使得國家愛睡眠基金會所建議的9個小時的睡眠時間幾乎是不可能的。此句真正的賓語是后面的動詞不定式，國家愛睡眠基金會所建議的9個小時的睡眠時間。因此用it作形式賓語。故答案為it。

【3】句意：如果青少年按照所建議的時間去睡眠的話，他們的健康狀況及學(xué)習(xí)成績就會改善。此處缺少謂語，would后跟動詞原形。依據(jù)句意，故答案為improve。

【4】句意：依據(jù)國家愛睡眠基金會的調(diào)查。according to 依據(jù)，根據(jù)的意思。依據(jù)句意，故答案為According。

【5】句意：只有大約15%的青少年在晚上10:45前睡覺。下句提到5%的學(xué)生在10:45上床睡覺，依據(jù)句意，15%的青少年應(yīng)該在晚上10:45前睡覺。故答案為before。

【6】句意：為什么不能采取措施來幫助青少年提高睡眠時間呢？從句子結(jié)構(gòu)可以看出，此句是含有情態(tài)動詞的被動語態(tài)。依據(jù)句意，故答案為done。

【7】句意：研究表明青少年睡眠九個半小時很少有遲到及健康問題。and并列連詞，由前面的less可知，此空應(yīng)該填一個比較級。依據(jù)句意，且problems為可數(shù)名詞，故答案為fewer。

【8】句意：充足的睡眠更加有助于學(xué)生關(guān)注老師所講話的內(nèi)容。此句是一個賓語從句，從句缺少賓語，故用疑問代詞what作為引導(dǎo)詞。
