【1】詞義猜測題。根據(jù)劃線單詞所在的語境Nearly 63 percent of Chinese youths aged 6 to 17 sleep less than eight hours a day, according to the report.，這句話是對上文的一個解釋，說的是中國的很多兒童和青少年每天的睡眠不足，少于八個小時。由此可推測adequate意為“足夠的”，故應(yīng)選A。

【2】推理判斷題。根據(jù)短文第四段Gao Xuemei, vice-president of the society, said studies have shown that decreasing (減少)sleeping time for children and teenagers has been a global trend in the past 10 years, but the problem appears to be worse in East Asia, including China, largely clue to a heavier load of school homework.可知，研究表明兒童和青少年睡眠減少在過去的10年里一直是全球的一個趨勢，但東亞的問題似乎更嚴重。由此可知，東亞孩子的睡眠時間比世界上其他地方的孩子更少。故D選項符合文意。

【3】推理判斷題。短文中作者介紹了中國睡眠研究會做的報告，并引用該協(xié)會副總裁的話，強調(diào)了這一現(xiàn)象的嚴重性，其寫作目的是引起人們對兒童和青少年缺乏睡眠這一現(xiàn)狀的重視。故D選項符合文意。
