高考英语考纲词汇用法详解(上)

【注意】1.单数可数名词若泛指,其前需加 a / an,不要从汉语习惯出发,漏掉此不定冠词(高考短文改错中常考查此知识点,许多同学在做书面表达时也常犯此错),如不能说mr. smith is interesting man.(需在 is后 加 an) 2.在序数词之前使用a(an),可以表示数量或序数的增加:do you want to read it a third time? 你还想看第三次吗?
able[5eibl] adj.能…的,有才能的,能干的,能够的:she’s as clever and able as her sister. 她像她姐姐一样聪明能干。
【句型】be able to do sth 能做某事
【说明】比较级和最高级可以是 abler 和 ablest 或 more able, better able 和 most able,但不如前者常见。
【辨析】be able to 与 can的区别,见 can。
