译林英语七上Unit4语法讲解及习题:时间介词+频率副词
一、语法核心精讲
(一)时间介词(Prepositions of time)
用于描述动作发生的时间,需根据时间的“范围大小”选择对应介词。
介词
适用时间类型
具体示例
例句
in
①一天中的部分时段(早/中/晚)
②月份
③季节
④年份
in the morning/in July/in autumn/in 2025
We have art class in the afternoon.
on
①具体某一天
②具体日期
③带修饰的某天时段(如“星期X的上午”)
④特殊节日
on Monday/on 5th March/on Sunday evening/on National Day
They will have a party on Children’s Day.
at
①具体时刻(几点几分) ②年龄
③固定搭配(如at noon/at night)
at 3:45/at 12 years old/at noon
She usually goes to bed at 9:30.
(二)频率副词(Adverbs of frequency)
用于描述动作发生的“频率高低”,位置需根据动词类型调整。
1. 频率等级(从低到高)
never(0%)→ seldom(20%)→ sometimes(40%)→ often(60%)→ usually(80%)→ always(100%)
2. 位置规则
句中含实义动词:频率副词放“实义动词前”
例:He often plays basketball after school.
句中含be动词:频率副词放“be动词后”
例:She is always late for class.
