不愉快的事情用英语怎么说

"Unpleasant" 是不愉快的事情的常用译词。

举例：

"The experience was unpleasant." (这次经历不愉快。)
"She has an unpleasant habit of interrupting others." (她有一个不良习惯就是打断别人。)
"The weather was unpleasant, with heavy rain and strong winds." (天气不好,有大雨和强风。)

"unpleasant" 是由英语单词 "pleasant" 和 "un-" 前缀组成。 "pleasant" 意为 "令人愉快的"，而 "un-" 前缀表示 "相反的"，所以 "unpleasant" 就表示 "不令人愉快的"。
