词引力

adv. 罕见地；极其，非凡地

unusually、rarely、seldom、exceptionally
1. uncommonly：副词“不寻常地；罕见地；极其”（侧重程度或频率超出常规，搭配“uncommonly cold 异常寒冷；uncommonly clever 极其聪明”，如“It's uncommonly warm for this season. 这个季节天气异常暖和。”）；
2. uncommonly vs. unusually：unusually副词“不寻常地；异常地”（与uncommonly近义，如“unusually quiet 异常安静”），可换用，unusually更口语化；
3. uncommonly vs. rarely：rarely副词“罕见地；很少”（侧重频率低，如“rarely go out 很少出门”），uncommonly可指“程度高”，rarely无此含义；
4. uncommonly vs. exceptionally：exceptionally副词“极其；异常地”（侧重程度突出，如“exceptionally difficult 极其困难”），uncommonly可指“频率或程度”，exceptionally仅指“程度”。
