Last Sat Last Sun Mon / Yesterday Tue / Today We use the simple past tense to talk about actions in the past. e.g. I painted a picture yesterday. I studied for the English test last night. I chatted with my friends at the weekend. Simple past tense: regular verbs We usually add ed to the action words. e.g. listen look paint play listened looked painted played Simple past tense: regular verbs We double the last letter when the action words are one syllable and end in 1 vowel + 1 consonant. e.g. chat clap skip chatted clapped skipped We change the letter y into ied when the action words end in 1 consonant + y. e.g. dry tidy study dried tidied studied 一般过去时的谓语动词要用动词的过去式.动词过去式的构成分规则变化和不规则变化两种形式,不规则变化通常需要逐个记忆,规则变化则遵循以下原则： (1)?一般在动词后加-ed. 如：play—played, destroy—?destroyed(2)?在以字母e结尾的动词后,只加-d. 如：like—liked, provide—provided(3)?在以“辅音字母+y”结尾的动词后,则改y为i,再加—ed. 如：supply—supplied,fly—flied,study—?studied.(4)?在以单短元音的重读闭音节结尾且末尾只有一个辅音字母的动词后,双写最后一个辅音字母,再加-ed.如：plan—planned,refer—referred, ban—banned. Key structure yesterday? What did you do at the weekend? last night? I played games with my parents. Don’t change the action words in did questions. This means last weekend.
