【1】句意：也許這意味著你需要更多的睡眠。

根據(jù)前一句說(shuō)感覺(jué)疲倦或難以集中精力在課堂上，后一句說(shuō)沒(méi)有充足的睡眠會(huì)導(dǎo)致各種各樣的問(wèn)題可知，中間缺需要更多的睡眠，故選B。

【2】句意：一些美國(guó)小學(xué)生很累，有時(shí)他們甚至在課堂上睡著了。

根據(jù)美國(guó)學(xué)生也有同樣的問(wèn)題，后面是為什么他們這么疲倦，可知中間說(shuō)的是美國(guó)學(xué)生，根據(jù)所給選項(xiàng)，故選A。

【3】句意：許多孩子花很多時(shí)間上網(wǎng)。

根據(jù)前面71%的8到18歲的美國(guó)孩子房間里有電視，大約36%的孩子房間里有電腦。后面是玩電子游戲、給朋友發(fā)短信和看電視，可知中間是孩子花很多時(shí)間上網(wǎng)，故選D。

【4】句意：改變不良的睡眠習(xí)慣永遠(yuǎn)不會(huì)太遲。

根據(jù)前面是如何解決這個(gè)問(wèn)題，后面是花更多的時(shí)間在睡眠可以幫助學(xué)生保持健康，在學(xué)校表現(xiàn)良好，可知是方法去改變不好的習(xí)慣，故選C。

【5】句意：在學(xué)校表現(xiàn)很好。

根據(jù)前面說(shuō)改變不好的睡眠習(xí)慣，所以后面應(yīng)該是影響，可以幫助學(xué)生保持健康，在學(xué)校表現(xiàn)良好。故選E。
