at the beginning和in the beginning的区别，真没人搞得懂
at the beginning 与 in the beginning 的深度解析
at the beginning：
强调具体时间或事件的明确起点，通常后接"of"短语（如：at the beginning of the meeting）。
例：At the beginning of the novel, the author describes the setting.（小说开篇明确描述场景）
in the beginning：
泛指时间或过程的初始阶段，不特指某个具体起点，常独立使用。
例：In the beginning, I didn't understand the concept.（泛指学习过程的初期）
at the beginning：
必须搭配"of"引出具体对象（× at the beginning the class → √ at the beginning of the class）
in the beginning：
通常独立作时间状语，无需接"of"（√ in the beginning, we struggled）
可互换场景：
当泛指"最初阶段"且不强调具体对象时，两者可互换：
At the beginning/In the beginning, the project faced many challenges.
（但"in the beginning"更自然）
不可互换场景：
需接"of"短语时，只能用"at"：
× in the beginning of the 20th century
√ at the beginning of the 20th century
通过对比练习强化记忆：
"______ (at/in) the beginning, I thought it was easy, but ______ (at/in) the beginning of the exam, I realized my mistake."
