美防长称计划摧毁伊朗全部军事能力

Use “称” after a noun (usually a person or organization) to report what that person/organization said. It’s similar to “say” or “claim” in English.

Use “计划” before a verb to express a planned action or intention, often followed by the object of the action.

When talking about quantities, use “数量+（减少/下降）+了+amount/percentage” to show a decrease in numbers or amounts.

“已经” before a verb, often followed by “了”, indicates that an action has already been completed.

This structure uses double negatives to express that something is not allowed without a certain condition, e.g., “未经授权不得转载” means “you may not reprint without authorization.”
