🎯 这节课你会学到

  1. in / on / at 的时间与地点分工(口诀化)
  2. 专升本完形、词汇题最爱考的动词 + 介词搭配

📖 讲解

1. 时间三兄弟:in / on / at(从大到小)

词范围例句
in大块时间:年 / 月 / 季节 / 早晚in 2026 / in May / in spring / in the morning
on具体某一天 / 某天早上on Monday / on May 1st / on Sunday morning
at具体时刻 / 小节点at 7 o’clock / at noon / at night / at that time

口诀:年月季节用 in,具体某天用 on,几点几分用 at。

⚠️ 易混点:in the morning(泛泛的早上)vs on Sunday morning(特指周日早上——一旦「某天」上身,in 就变 on)。

2. 地点三兄弟

词范围例句
in内部(大空间)in the room / in China / in the car
on表面 / 上面接触on the desk / on the wall / on the bus
at一个点(门口、站点、场合)at the door / at the bus stop / at school / at home

3. 高频动词 + 介词搭配(完形词汇题弹药库)

搭配意思搭配意思
look at看listen to听
look for寻找wait for等待
look after照顾belong to属于
look forward to doing期待(to 是介词!)depend on依靠
be good at擅长arrive at(小地)/ in(大地)到达
be interested in对…感兴趣agree with(人)/ to(事)同意
be afraid of害怕be proud of自豪
be full of充满be famous for(因…出名)/ as(作为…出名)出名
spend…on sth / (in) doing花费stop…from doing阻止
thank sb for sth因…感谢help sb with sth帮忙

4. 三个高频易混组

  1. arrive at / in / reach / get to:arrive at 车站(小地点);arrive in 北京(大地点);reach 和 get to 直接加地点(不加介词)
  2. spend / cost / take / pay:人 spend 时间钱 on sth;物 cost 钱;it takes 时间 to do;人 pay 钱 for sth
  3. between(两者之间)vs among(三者及以上)

⚠️ 零基础最容易犯的错

  1. on + 星期几:❌ in Monday → ✅ on Monday
  2. at night / in the night:习惯是 at night
  3. look forward to / be used to 后面的 to 是介词 → 接 doing:❌ look forward to hear → ✅ to hearing

  2. My birthday is ____ October 1st.
  3. The meeting begins ____ 9:00 ____ the morning.
  4. He arrived ____ Shanghai yesterday.(大地点)
  5. 选词:She is interested ____ (in / on) music.
答案(先自己写!)
