56 D energy bill指消耗電、汽等能源的賬單。其他幾個選項的意思與上下文不符。
57 B 根據(jù)上下文這里指使用最多的是燈泡,因為長時間使用這樣的燈泡耗電量大,所以要把這些燈泡換成節(jié)能型。
58 D 這里要用介詞0ver,表示跨越很長時間。
59 A 從上下文來看,接下來文章進一步說明節(jié)能燈泡的好處,故用表示遞進的詞moreover。
60 c set的意思是“設(shè)定”,其他幾個詞意思與文章不符。
61 B 此句的意思是當你使用電視、收音機等設(shè)備時要關(guān)掉它們,故選using。
62 D 此處的意思是離開房間時忘了關(guān)閉它們,故選forget。
63 A 此旬的意思是,天氣晴朗的時候,要打開百葉窗,讓陽光進來。從上下文判斷,只能選A。
