🎯 这节课你会学到

把前六课装进一张表，然后用 12 道混练题检验——这 12 题的水平，就是你现在做专升本语法题的水平。

📖 六大时态总表（保存这一页，考前就背它）

时态结构标志词例句
一般现在时动词原形（三单 + s）always / usually / every dayHe goes to school every day.
一般过去时动词过去式yesterday / last / …ago / in 2020He went to school yesterday.
一般将来时will + 原形 / be going totomorrow / next / soon / in 2030He will go to school tomorrow.
现在进行时be + doingnow / Look! / Listen!He is going to school now.
现在完成时have / has + 分词since / for / already / just / yet / everHe has gone to school already.
一般过去(be)was / were同一般过去时He was at school yesterday.

做题流程（四步，每题都走一遍）

  1. 找标志词（now？yesterday？since？tomorrow？）
  2. 没有标志词 → 看上下文时间（前一句是昨天的事？）
  3. 定时态 → 按结构表写动词
  4. 最后检查：三单？分词形式对不对？

📝 混练 12 题（先盖住答案）

  2. My father ____ (read) newspapers every morning.
  3. They ____ (visit) the Great Wall last summer.
  4. I ____ (not / see) him since last month.

  10. 改错：She have studied English for three years.
  11. 改错：Did you saw the movie last night?
  12. 改错：Look! It rains outside.
答案与解析（对照四步流程检查）

  2. reads（every day 类标志 → 一般现在；father 三单 → +s）
  3. visited（last summer → 过去；规则动词 + ed）
  4. haven’t seen（since → 完成时否定；see 的分词是 seen）
  5. Have you finished…?（yet → 完成时疑问；have 提前）
  6. has been（for + 时间段 → 完成时；she → has；be 的分词 been）
  7. will have / are going to have（tomorrow → 将来）
  8. is knocking（Listen! → 进行时；someone 三单 → is）
  9. bought（two days ago → 过去；buy 不规则 → bought）
  10. have ❌ → has studied（she 三单用 has）
  11. saw ❌ → see（Did 后面用原形）
  12. rains ❌ → is raining（Look! → 进行时）

错 3 题以内：合格，继续往下学。错 4 题以上：把第 4、5、8 课重读一遍再做混练，别硬闯。
