3 One special feature of Crystal Ear is that
A you can control its volume．來源：考試大
B you needn’t take it off everyday．
C it is solar-powered．
D it saves power．來源：考試大
D．分析：問題問及水晶耳的一個(gè)特性，利用題干中出現(xiàn)的修飾詞special作為答案線索，但是在文章中沒有發(fā)現(xiàn)該詞以及該詞的近義詞所以對(duì)照被選項(xiàng)中的核心詞/結(jié)構(gòu)在文章中進(jìn)行查找確認(rèn)，而被選項(xiàng)C和D在含義上有關(guān)系，猜測(cè)答案來自這兩個(gè)選項(xiàng)中。
Almost 90 percent of people with mild hearing loss，and millions more with just a little‘hearing drop-off(下降)，can be dramatically helped with Crystal Ear．Moreover, its superior design is energy-efficient，so batteries can last months．（該句句意直接揭示D是答案）Crystal Ear is now available to help these people treat their hearing loss with a small hearing amplifier(放大器)．
