摘要：易错陷阱：“早中晚”前有修饰词（如cold morning）时，用on不用in；“在学校”是at school（固定搭配），不用in。

沈阳沈阳六年级英语“介代情动词四用法”详解、辨析及易错陷阱填空专练阳（40道附解析）

一、“四用法”核心详解与辨析（六年级高频考点）

1. 介词in/on/at（时间/地点用法）

- 核心区别：范围从大到小——in（年/月/季节/大地点）、on（具体日期/星期/具体某天的早中晚）、at（具体时刻/小地点）。

- 易错陷阱：“早中晚”前有修饰词（如cold morning）时，用on不用in；“在学校”是at school（固定搭配），不用in。

2. 代词it/this/that/these/those（指代用法）

- 核心区别：it指代单数名词/不可数名词（同名同物）；this/that指代单数（近指/远指）；these/those指代复数（近指/远指）。

- 易错陷阱：回答“What's this/that?”时，统一用it代替，不用this/that（如It's a pen，而非This is a pen）。

3. 情态动词can/may/must/should（语气用法）

- 核心区别：can（能力“能”）、may（许可“可以”/请求）、must（义务“必须”，语气最强）、should（建议“应该”，语气较弱）。

- 易错陷阱：must的否定是needn't（“不必”），不是mustn't（“禁止”）；can表能力时，否定用can't（“不能”）。

4. 动词have/has/there be（“有”的用法）

- 核心区别：have/has表“某人拥有”（主语是人/物），has用于第三人称单数；there be表“某地有某物”（就近原则）。

- 易错陷阱：“某地有某人”也用there be（如There is a boy in the room），不用have；have/has的否定是don't/doesn't have，不是haven't/hasn't（六年级阶段）。
