Simple past tense
Present perfect tense
Tday we are ging t learn hw t cmpare “simple past tense" and “present perfect tense“.
Learning t understand
Simple Past（过去时，带明确过去时间标志）标志词：ag, used t + 动词原形（描述过去常态，现在不再）
Present Perfect（现在完成时，无明确过去时间，关联现在）标志词：yet, just, ever, fr, since
Yes, he did./N,he didn’t.
She used t have curly hair.
表示过去习惯性的动作或经常性的状态，现在已经不存在。
She is used t getting up early.
be/get used t ding
习惯于做某事（可用于现在、过去、将来等多种时态）
The knife is used t cut fruit.
be used t d
被用来做某事（是被动语态, 用于多种时态）
一般过去时和现在完成时的区别
一般过去时：was/were 或 动词的过去式现在完成时：have/has + 动词的过去分词
一般过去时：陈述过去发生的事情或 存在的状态现在完成时：强调造成的结果或对现在 产生的影响
一般过去时：具体的表示过去的时间状语现在完成时：表示频度或一段时间的状语
句式结构不同(行为动词)
句式结构不同(be动词)
一般过去时：表示过去某个时间发生的事情或存在的状态， 说话的侧重点在陈述过去发生的事情或存在的状态。e.g. I went t the library yesterday. 动作: 去图书馆 时间: 昨天（明确过去时间） 结果: 现在是否在图书馆？不知道，不关心。
现在完成时：表示到说话时为止已经发生(不一定结束)或完成的 动作或状态，强调造成的结果或对现在产生的影响。e.g. He has lived here fr 10 years. 动作开始: 10年前搬到这里 持续状态: 一直住在这里（从过去到现在） 现在情况: 现在仍住在这里（●） 未来可能: 还可能继续住下去（►）
一般过去时：通常与yesterday, last week, tw years ag, just nw, in 2022等具体的表示过去的时间状语连用。现在完成时：通常与already, never, many times, s far, till nw, recently, these days等表示频度或一段时间的状语连用。e.g. I ________ t the z last week. 上周我去了动物园。 My father ________ that watch ten years ag. 我爸爸10年前买了那块手表。 He ______ already _________ his hmewrk. 他已经完成了家庭作业。 I ______ never ________ the film befre. 我以前从没看过这部影片。
has finished
have seen
拓展：延续性动词/非延续性动词
一般过去时既可以用延续性动词, 也可以用短暂性动词(瞬间动词/非延续 性动词)，没有任何限制！限制只存在于现在完成时中（特别是与 fr / since 连用时）。e.g. He died tw years ag. He has died fr tw years. ❌ 应改为：He has been dead fr tw years. ✅ 常见的短暂性动词 → 延续性动词转换: die → be dead leave → be away brrw → keep buy → have pen → be pen clse → be clsed jin → be in / be a member f begin/start → be n arrive/reach/get t → be in/at marry → be married
