Life has a nasty habit of repeating itself. He had a nasty accident while riding in the forest. When you feel you’ve been cheated, it always leaves a nasty taste in the mouth (=makes you feel upset or angry afterwards) . The weather turned nasty towards the evening.
生活总是令人厌烦地重复着。 他在森林中骑马时出了严重的事故。 你发现受骗时,总会有一种懊恼的感觉。 傍晚时分天气变坏了。
