        zh: "一般过去时表示已结束、不延续到现在的动作。",
        body: "We use the past simple to talk about actions and situations that finished at a definite time in the past. The action is over. It does not continue into the present. Often a time word tells us when: yesterday, last Friday, in 2019, three years ago. Sometimes the time is simply understood because we are telling a story. The past simple is the main tense for stories and for talking about your day.",

        body: "Many verbs are regular: we add -ed to the base form. The spelling needs a little care. If a short verb ends in one vowel plus one consonant, we double the consonant: stop → stopped, plan → planned. A consonant plus -y changes to -ied: study → studied, carry → carried. Verbs already ending in -e simply add -d: like → liked, dance → danced. Say each new form aloud and you will soon feel the pattern.",
        examples: ["She watched a film after dinner.", "He studied until midnight.", "They stopped at the red light."],

        zh: "最常用的动词往往不规则,只能像生词一样逐个记住。",
        body: "Many of the most common verbs are irregular: their past forms do not end in -ed, and there is no single rule. You learn them one by one, like new words. Grouping helps. Some change their vowel: see → saw, give → gave, write → wrote. Some change completely: go → went, buy → bought, think → thought. A few never change at all: cut → cut, put → put. Learning ten at a time is much easier than fifty.",
