考点28：系动词的基本用法
系动词是连接主语和表语（充当表语的词类主要是形容词和名词）的动词，系动词跟情态动词一样本身具有词义，但系动词不能单独用作谓语，后边必须跟表语（简略答语等特殊情况除外）。下表是对高考中有可能出现的系动词及其用法的总结：
［例1］ Some people eat with their eyes. They prefer to order what ____ nice.
A. looks
B. smells
C. feels
D. tastes
［答案］ A
［解析］ 与前面的“eat with their eyes”相对应，下划线处应填入表示“看”的系动词。
［例2］ Please remain ____; the winner of the prize will be announced soon.
A. seating
B. seated
C. to seat
D. to be seated
［答案］ B
［解析］ 题干中的remain为系动词，意为“保持，仍是，尚待”，而这里的seat是表示“让某人坐”的及物动词（常见用法是somebody be seated 或seat somebody/oneself的形式），四个选项中seated最适合填入下划线处充当系动词remain的表语，其在此处也可用sitting代替。
