赤子之心是助人实现理想的正能量。______ ______ _____ ______ 。而赤子之心则能赋予我们追求理想的执着。
①孟子说：“大人者，不失其赤子之心者也。”即有大成就的人都有一颗婴儿般的心。
②他们选择职业时，仅看到行业的光鲜和收入的可观，却看不到背后的辛苦和压力。
③这样的人一旦遇到困难就会灰心丧气，停步不前，何谈实现理想?
④但是，许多年轻人是从功利的角度确立目标的。
文本阐述的是“赤子之心是助人实现理想的正能量”，首先用①句孟子说的“大人者，不失其赤子之心者也”从正面阐述观点；接着用④句从反面列举许多年轻人从功利的角度确立目标；②句则紧承④句作具体解说许多年轻人选择职业时的“功利”；③句承接②指出这类人最终表现。据此，正确的句序是：①④②③。故选B。
