Suddenly
“Suddenly” 用于描述变化发生得很快、几乎没有预告。它常出现在叙事句中，用来制造转折和即时感。
- “Suddenly, the lights went out.” (突然，灯灭了。)
- “She suddenly realized she had left her keys at home.” (她突然意识到自己把钥匙落在家里了。)
- “The weather changed suddenly in the afternoon.” (下午天气突然变化了。)
该词源自 sudden（突然的），语义核心是“无预兆的快速变化”。
“Suddenly” = sudden + -ly，将形容词转为副词，表示“突然地发生”。
在英语故事写作中，suddenly 是常见的节奏词，用于增强戏剧感和读者注意力。
- 固定搭配: “suddenly realize” (突然意识到), “suddenly appear” (突然出现)
- 相关词: “sudden” (突然的), “suddenness” (突然性)
记住 sudden（突然）后，加 -ly 就是“突然地”。
“Everything was quiet, and then suddenly a puppy ran into the room and made everyone laugh.” (一切都很安静，突然一只小狗冲进房间，把大家都逗笑了。)
