【解析】

根據(jù)中國(guó)睡眠研究會(huì)周日發(fā)布的一份報(bào)告顯示，超過(guò)60%的兒童和青少年睡眠不足，這對(duì)他們的健康非常有害。文章中分析，造成這一結(jié)果的主要原因是學(xué)校作業(yè)以及使用電子設(shè)備。

【1】詞義猜測(cè)題。根據(jù)劃線單詞所在的語(yǔ)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(duì)上文的一個(gè)解釋?zhuān)�說(shuō)的是中國(guó)的很多兒童和青少年每天的睡眠不足，少于八個(gè)小時(shí)。由此可推測(cè)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(guò)去的10年里一直是全球的一個(gè)趨勢(shì)，但東亞的問(wèn)題似乎更嚴(yán)重。由此可知，東亞孩子的睡眠時(shí)間比世界上其他地方的孩子更少。故D選項(xiàng)符合文意。

【3】推理判斷題。短文中作者介紹了中國(guó)睡眠研究會(huì)做的報(bào)告，并引用該協(xié)會(huì)副總裁的話，強(qiáng)調(diào)了這一現(xiàn)象的嚴(yán)重性，其寫(xiě)作目的是引起人們對(duì)兒童和青少年缺乏睡眠這一現(xiàn)狀的重視。故D選項(xiàng)符合文意。

這是一篇議論文文，短文介紹了中國(guó)睡眠協(xié)會(huì)的一個(gè)報(bào)告，報(bào)告顯示大多數(shù)的兒童和青少年睡眠不足，這對(duì)他們的健康是非常有害的。文章主題明確，論點(diǎn)清晰，論據(jù)充分，內(nèi)容貼近學(xué)生們的日常生活，比較容易理解。題型是閱讀理解，考查學(xué)生們閱讀短文掌握大意、獲取細(xì)節(jié)信息、猜測(cè)生詞含義以及進(jìn)行合理的推測(cè)和判斷的能力。做題時(shí)，應(yīng)先通讀短文，了解文章大意；然后根據(jù)題目所問(wèn)，用查讀法，并結(jié)合語(yǔ)境和選項(xiàng)做題。如第1小題，這是一個(gè)猜測(cè)詞義的題目，根據(jù)劃線單詞所在的語(yǔ)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(duì)上文的一個(gè)解釋?zhuān)�說(shuō)的是中國(guó)的很多兒童和青少年每天的睡眠不足，少于八個(gè)小時(shí)。由此可推測(cè)adequate意為“足夠的”，故應(yīng)選A。第3小題詢問(wèn)的是作者的寫(xiě)作目的，這樣的題目應(yīng)從文章的大意出發(fā)，結(jié)合選項(xiàng)選擇最佳答案。這篇短文中作者介紹了中國(guó)睡眠研究會(huì)做的報(bào)告，并引用該協(xié)會(huì)副總裁的話，強(qiáng)調(diào)了這一現(xiàn)象的嚴(yán)重性，其寫(xiě)作目的是引起人們對(duì)兒童和青少年缺乏睡眠這一現(xiàn)狀的重視。故D選項(xiàng)符合文意。
