与此同时

• 拼音: yǔ cǐ tóng shí
• 汉字拆解: 与 = with/and; 此 = 止 + 匕 (foot + pointing — this/here); 同 = 口 + 冃 (mouth + cover — together/same); 时 = 日 + 寺 (sun + measure — time)

含义

At the same time; meanwhile; simultaneously. A discourse connective used to introduce a concurrent development, condition, or action.

A standard formal connective in written Chinese, especially in academic writing, news reporting, and policy documents. Links two simultaneous but distinct developments, often in different domains or affecting different parties. More formal and literary than 同时 (at the same time) alone. Commonly appears at the start of a sentence or clause to signal a parallel development.

例句

3. 七年内战摧毁了该国工业基础，也使数百万人陷入贫困；与此同时，大量难民外逃，加重了邻国安置压力。
