【解析】

本文是一篇說明文，講述了良好健康睡眠的重要性。

【1】句意：每年都有一天世界各地的人們來慶祝良好健康睡眠的重要性——世界睡眠日。

importance重要性；influence影響；difference不同；habit習(xí)慣。根據(jù)關(guān)鍵詞“good and healthy sleep”和“World Sleep Day”可推測(cè)出是在講好的健康的睡眠的重要性。故選A。

【2】句意：睡眠就像給大腦提供食物。

arm胳膊；brain大腦；leg腿；shoulder肩膀。根據(jù)后句“A good amount of sleep helps the body and brain grow” 充足的睡眠有助于身體和大腦的成長(zhǎng)�？赏茰y(cè)出應(yīng)該是睡眠就像給大腦提供食物。故選B。

【3】句意：充足的睡眠有助于身體和大腦的成長(zhǎng)和發(fā)展。

disappear消失；discover發(fā)現(xiàn)；develop發(fā)展；destroy破壞。根據(jù)and連接兩個(gè)相同的詞，可知其后要跟一個(gè)動(dòng)詞，根據(jù)語境我們會(huì)聯(lián)想到grow and develop“成長(zhǎng)和發(fā)展”，符合題意，故選C。

【4】句意：不同年齡的人需要不同的睡眠時(shí)間。

countries國(guó)家；names名字；ages年齡；jobs工作。結(jié)合“different amounts of sleep”以及選項(xiàng)，這里講的是不同年齡階段的人。故選C。

【5】句意：成年人每晚需要七到九個(gè)小時(shí)的睡眠。

doctors醫(yī)生；parents父母；scientists科學(xué)家；adults成年人。根據(jù)選項(xiàng)，選項(xiàng)A、B、C都屬于成年人，結(jié)合常識(shí)，可推知說的是成年人的睡眠時(shí)間。故選D。

【6】句意：健康的睡眠時(shí)間大約是每晚八到九個(gè)小時(shí)。

impossible不可能的；different不同的；difficult困難的；healthy健康的。結(jié)合常識(shí)和句意，我們可推知健康的睡眠所需要達(dá)到的量為八到九個(gè)小時(shí)。故選D。

【7】句意：然而，許多學(xué)生因?yàn)殚_學(xué)時(shí)間過早和作業(yè)過多而睡眠不足。

Besides除…之外，還有；Otherwise否則；Also也；However然而。很明顯，上一段和本段是存在著轉(zhuǎn)折關(guān)系，故選D。

【8】句意：中國(guó)青少年研究中心報(bào)告說，大約80%的中學(xué)生睡眠不足。

good好的；long長(zhǎng)的；enough足夠的；many很多。根據(jù)前句，可推測(cè)出這里談到的是中學(xué)生得不到足夠的睡眠。故選C。

【9】句意：睡眠不足會(huì)極大地影響一個(gè)人的生活。

closely接近地；greatly極大地；hardly幾乎不；mostly通常。根據(jù)本句大意，說的是睡眠不足影響一個(gè)人的生活的程度。根據(jù)后句大意能影響到學(xué)生的成績(jī)，說明程度很大，故選B。

【10】句意：睡眠不足的學(xué)生可能成績(jī)不好。

who定語從句的引導(dǎo)詞，指代人；which定語從句的引導(dǎo)詞，指代物；whom定語從句的引導(dǎo)詞，作賓語；what引導(dǎo)主語從句。很明顯，這里是一個(gè)定語從句，說明是睡眠不足的學(xué)生。故選A。

【11】句意：他們不能在課堂上專心聽講，也不能在體育運(yùn)動(dòng)中表現(xiàn)出色。

visit拜訪；work工作；money金錢；attention注意。根據(jù)pay attention集中注意力。符合題意，故選D。

【12】句意：科學(xué)家建議學(xué)生應(yīng)該少做作業(yè)，多睡覺。

more更多；much很多；less更少；fewer更少（修飾可數(shù)名詞）。根據(jù)第三段的第一句“however，many students don't get enough sleep because of early school start times and too much homework.”可知，學(xué)生的作業(yè)太多，科學(xué)家建議少做作業(yè)，含有比較級(jí)的意味。homework是不可數(shù)名詞。故選C。

【13】句意：還有其他一些方法可以幫助人們獲得充足的睡眠，比如白天小睡20分鐘。

Making制作；taking帶走；catching抓�。�sleeping睡覺。根據(jù)take a nap“休息一下”固定搭配。故選B。

【14】句意：好的睡眠習(xí)慣也有幫助。

harmful有害的；helpful有幫助的；thankful感激的；wonderful精彩的。前兩句談到了怎樣得到充足的睡眠。可知，這里說到應(yīng)該是，好的睡眠習(xí)慣也有助于得到充足的睡眠。故選B。

【15】句意：試著每天在同一時(shí)間睡覺和起床，即使是在周末和假期。

even即使；always總是；usually通常；never從不。上一句談到了好的睡眠習(xí)慣有助于充足的睡眠。本句要說的是怎樣才算是一個(gè)好的習(xí)慣，就是每天的同一時(shí)間睡覺，即使是在周末和假期。故選A。

抓句子主干而不拘泥于微小的細(xì)節(jié)做題也是我們解決完形填空的一個(gè)辦法。比如：本題的空格10和11，雖然空格9沒有填上單詞，但是我們可以抓住句子主干——缺乏睡眠能影響一個(gè)人的生活。后面是說沒有充足睡眠的影響：學(xué)生沒有充足的睡眠，可能導(dǎo)致成績(jī)不好。在課堂上不專心，在體育課上表現(xiàn)不出色，推出空格11的答案pay attention。再去做10題，從結(jié)構(gòu)上看，屬于定語從句，就容易做了。
