Part 1 习新知法 —— 介词与频度副词
一、时间介词 at / in / on
时间介词是初一英语的难点和重点，at/in/on的区分:
介词 | 用法 | 举例 |
at | 具体时刻 / 年龄 | at 7 o'clock / at night / at noon / at the age of 12 |
in | 年/月/季节 / 早中晚 | in 2024 / in May / in summer / in the morning |
on | 具体某天 / 星期/日期 | on Monday / on June 1st / on my birthday |
-- I get up at 6:30. / My birthday is in May. / See you on Monday.
-- 注意: in the morning, but on Sunday morning (具体某天的早晚用on)
二、方位介词
方位介词表示位置关系:
介词 | 含义 | 例句 |
in | 在...里面 | The pen is in the pencil case. |
on | 在...上面(接触) | The book is on the desk. |
under | 在...下面 | The cat is under the chair. |
next to | 在...旁边 | The library is next to the gym. |
between...and | 在...之间 | The desk is between the two chairs. |
across from | 在...对面 | The bank is across from the school. |
三、频度副词
频度副词表示动作发生的频率，按频率高低排列:
频度副词 | 频率 | 例句 |
always (总是) | 100% | She always gets up at 6:00. |
usually (通常) | 80% | I usually go to school by bus. |

often (经常) | 60% | He often plays football. |
sometimes (有时) | 40% | Sometimes we go to the library. |
never (从不) | 0% | I never eat junk food. |
频度副词的位置:
* be动词之后: She is always happy. / They are never late.
* 实义动词之前: He often reads books. / I usually get up at 7:00.
* sometimes也可在句首: Sometimes I go swimming.
