易错句子He fell into the bait.
正确表达He fell for the bait.
英语中表示“上钩、中计”的固定搭配是 fall for the bait 或 take the bait，不能说 fall into the bait；fall into 通常与 trap 等搭配，汉语“落入陷阱”容易迁移成 fall into the bait。
bate 与 bait 读音相同，但词性和意思完全不同：bate 是动词，表示“减弱、抑制”，最常见于固定短语 with bated breath（屏息）；bait 是名词，指用来引诱的“诱饵”。写作时别把 bated breath 误拼成 baited breath。
bite 读 /baɪt/，bait 读 /beɪt/，元音不同，中文学习者常听混。bite 指“咬”这个动作或咬下的一口；bait 则是捕猎或设局用的“诱饵”，是具体的东西。
两者都可译作“诱饵”，但 lure 强调事物本身的吸引力或魅力，常用于比喻（如 the lure of the sea 大海的诱惑），语气较中性；bait 指实实在在用来诱捕动物的饵料，并带有“设套让人上当”的算计意味。
