参考答案及解析
1.B 考查数字。分数的表达是：分子用基数词，分母用序数词，分子大于一时，分母用复数形式，故“五分之三”是threefifths, “20世纪90年代”用1990s或1990’s表示。
2. D 考查介词。over在...上面；under在...下面；across穿过，指的是从物体表面穿过；through穿过，指的是从立体空间穿过。jungle意为“丛林”，故用介词through。trekthrough the jungle 指“穿越丛林”。
3. B 考查动词remember的用法。该句意为“当你离开教室时，记住把灯关上”。表示“记住做某事(事情并没有做)”用rememberto do sth.。
4.C 考查副词。根据句意可知“水龙头开着”，表示“使用中”用副词on。
5. A 考查should的用法。should为情态动词，后接动词原形。
