1. 以后缀 –ed结尾的形容词(如ashamed, delighted, excited, frightened, interested, moved, pleased, surprised, worried等)通常用于说明人,不用于说明事物,即使它们所修饰的名词是事物,那它们指的也是与该事物相关的人。如:He had a pleased smile on his face. 他脸上露出了满意的微笑。He told me the news in a very excited voice. 他声音很激动地告诉了我这个消息。第一句中的a pleased smile 意为“满意的微笑”,它指的是某人因感到满意发出的微笑;第二句中的 a very excited voice 指的是“很激动的声音”,即指的是某人因很激动而发生那样的声音。原则上,-ed 形容词通常直接用于说明人,若修饰事物,则多为 air(神态), appearance(外貌), cry(哭声), face(表情), voice(声音), mood(情绪)<'Times New Roman'">), mood(等显示某人的情感状况的名词。2. 以后缀 -ing 结尾的形容词(如delighting, exciting, frightening, interesting, moving, surprising, worrying 等)主要用于说明事物,表示事物的性质或特征,若用它们说明人,则表示此人具有此性质或特征。如:The story is very interesting. 这个故事很有趣。The man is very interesting. 这个人很有趣。请再比较并体会以下句子:He is frightened. 他很害怕。He is frightening. 他很吓人。He has a frightened look on his face. 他脸上带有惊恐的神情。He has a frightening look on his face. 他脸上带有吓人的神情。I read an interested expression on his face. 我看到他脸上露出一种感兴趣的表情。
