一、一般现在时（经常性动作 / 事实）
时间状语：
· 频率副词：always, usually, often, sometimes, seldom, never
· 周期性时间：every day/week/month/year, on weekends, twice a week
· 客观真理：无特定时间词（如 The earth moves around the sun.）
例句：
She always reads books after dinner. ��
My parents go to work by bus every day. ��
易错点：
“every + 时间” 不一定全用现在时！
→ 若描述过去的习惯（如 “去年每天”），需用一般过去时：
Last year, I walked to school every day.
⏳ 二、一般过去时（过去某时的动作 / 状态）
时间状语：
· 具体过去时间：yesterday, last week/month/year, the day before yesterday
· 时间段 + ago：three days ago, five years ago
· 其他：just now, in 2020, at the age of 10
例句：
They visited the museum last Sunday. ��
I met my friend ten minutes ago. ��
易错点：
“ago” 必须搭配过去时，而 “before” 可用于完成时！
→ 错：I have seen the movie three days ago.
→ 对：I saw the movie three days ago. / I have seen the movie before.
�� 三、一般将来时（未来发生的动作）
时间状语：
· 未来时间：tomorrow, next week/month/year, the day after tomorrow
· 介词短语：in + 时间段（in two hours, in a few days）
· 其他：soon, later, in the future, right away
例句：
We will have a picnic next Saturday. ��
She is going to visit Beijing in three days. ✈️
易错点：
“in + 时间段” 表 “多久之后”，用于将来时；“after + 时间点” 可用于过去 / 将来！
→ He will come back in a week.（一周后，将来）
→ He came back after a week.（一周后，过去）
�� 四、现在进行时（此刻正在进行的动作）
时间状语：
· 此刻时间：now, right now, at the moment, at present
· 提示词：look!, listen!, “It’s + 具体时间”（如 It’s 8:00 p.m.）
例句：
Look! The kids are playing basketball now. ��
My mother is cooking dinner at the moment. ��
易错点：
“瞬间动词”（如 come, go, leave）的进行时可表将来！
→ She is leaving for Shanghai tomorrow.（表将来计划）
�� 五、过去进行时（过去某时正在进行的动作）
时间状语：
· 过去具体时间：at 9:00 last night, this time yesterday, at that moment
· 背景动作：while/when 引导的时间状语从句（从句用一般过去时）
例句：
I was doing homework when my dad came back. ��
They were watching TV at 8 p.m. yesterday. ��
易错点：
“while” 后接延续性动词（用进行时），“when” 后可接瞬间 / 延续性动词！
→ While she was reading, the phone rang.（延续性动作）
→ When she read the letter, she cried.（瞬间动作）
六、现在完成时（过去动作对现在的影响）
时间状语：
· since + 时间点：since 2020, since three years ago, since he left
· for + 时间段：for five days, for a long time
· 不确定时间：already, yet, just, ever, never, recently
例句：
I have lived here since I was born.
She hasn’t finished her work yet.
· 易错点：
“have been to”（去过已回）vs. “have gone to”（去了未回）！
→ He has been to Beijing three times.（去过）
→ He has gone to Beijing.（还没回来）
七、过去完成时（过去的过去）
时间状语：
· by + 过去时间：by the end of last year, by the time sb. did sth.
· before + 过去动作：before 2020, before she came
例句：
By the time I arrived, the party had already started. ��
She had left the city before 2019. ��♀️
易错点：
必须有 “过去的时间” 作为参照，否则用一般过去时！
→ 错：I had finished my homework last night.
→ 对：I finished my homework last night.（无 “过去的过去”）
�� 八、过去将来时（从过去看将来的动作）
时间状语：
· 常用于宾语从句（主句为过去时）：the next day, the following week, soon
例句：
He said he would visit us the next day.
They thought it was going to rain soon.
⚠️ 易错点：
结构为 “would + 动词原形” 或 “was/were going to + 动词原形”，不可遗漏 be 动词！
→ 错：He said he is going to visit us.
→ 对：He said he was going to visit us.
�� 核心技巧总结
时间状语 “三看” 原则：
· 看 “时间词”（yesterday/tomorrow 等）直接判断时态
· 看 “介词”（in/after/since/for）锁定时态范围
· 看 “上下文”（无时间词时，通过动词时态推断）
易混时态对比表：
时态 | 时间状语关键词 | 例句对比 |
一般过去时 | ago, last, yesterday | I saw the movie yesterday. |
现在完成时 | since, for, already, yet | I have seen the movie before. |
过去完成时 | by + 过去时间，before + 过去动作 | I had seen the movie by 2020. |
错题急救包：
· 分不清 “in” 和 “after”？→ “in” 用于将来（in 2 days），“after” 可用于过去 / 将来（after 2 days then）
· 忘记 “have been to” 和 “have gone to”？→ 记 “been”=“去过已回”（有人在现场），“gone”=“去了未回”（人不在）
现在用 “since” 和 “by the end of last year” 各造一个句子，评论区打卡吧！正确率 + 20% ✅
