"stimulated by" 是动词短语 "stimulate"(刺激;激发;促使) 的被动形式,字面意为 "被……刺激/激发/促使",强调主语(人或物)受到某个外部因素的"触发",从而产生行动、反应或变化。
"stimulated by" 通常用于被动语态(be + stimulated + by + 刺激源),其中:
be动词:根据时态/主语人称变化(如is/was/has been等);
by:引出刺激源(即"导致激发的原因"),后接名词、代词或动名词(因为by是介词)。
"stimulated by" 可用于描述生理、心理、学术、创作等多种情境,核心是"外部因素引发内在反应":
强调身体或感官被外界因素激活:
The patient's nerve responses were stimulated by the electric current.(病人的神经反应被电流刺激。)

需注意"stimulated by"与其他"激发"类短语的差异:
inspired by(受……启发):更强调"灵感、创意的来源"(偏精神层面);
例:She wrote the poem inspired by her mother's love.(她写这首诗是受母亲爱的启发。)
motivated by(受……激励):更强调"行动的动机、目的"(偏目标导向);
例:He works hard motivated by the desire to support his family.(他努力工作是受养家的愿望激励。)
stimulated by:更侧重"外部因素引发的即时反应或生理/心理激活"(偏"触发");
例:The brain is stimulated by complex tasks.(大脑被复杂任务激活。)
"stimulated by" 是被动结构,核心是"主语被某因素刺激/激发",后接刺激源(名词/代词/动名词)。使用时需结合场景,区分与"inspired by""motivated by"的侧重,确保表达准确。
