在英语中,“afternoon”作为时刻名词,其前常搭配的词性及用法如下:


1. 介词(Preposition)

在表示时刻时,通常用in、on、at 等介词引导:

  • in the afternoon(泛指下午):
    例:We usually take a nap in the afternoon.
  • on + 具体某天下午:
    例:See you on Sunday afternoon.
  • at + 时刻点或特定搭配:
    例:The meeting starts at 3 o’clock in the afternoon.

2. 限定词(Determiner)

表示具体时刻范围时,可搭配this、that、every、yesterday、tomorrow 等限定词:

  • this afternoon(今天下午):
    例:Are you free this afternoon?
  • every afternoon(每天下午):
    例:She stu*s art every afternoon.
  • yesterday/tomorrow afternoon(昨天/明天下午):
    例:Where were you yesterday afternoon?

3. 形容词(Adjective)

描述下午的性质或情形时,可加形容词修饰:

  • a sunny afternoon(晴朗的下午):
    例:We had a picnic on a sunny afternoon.
  • a lazy afternoon(慵懒的下午):

4. 所有格代词(Possessive Pronoun)

表示所属关系时,可用my、your、their 等:

    例:My afternoon was busy with meetings.

注意事项

  • 省略介词的情况:
    当时刻词前有this、that、next、last、every 等时,无需加介词。例如:
    ?? Next afternoon we will go shopping.
    ?? On next afternoon

  • 固定搭配:
    如 “Good afternoon!”(下午好)是问候语,直接使用无需额外修饰.


“afternoon”前的常见词性包括:

  • 介词(in/on/at);
  • 限定词(this/every/yesterday);
  • 形容词(sunny/lazy);
  • 所有格代词(my/your)。

具体用法需结合语境,例如是否强调时刻段、具体日期或描述性质.
