be divided in purpose
❍ 他们首先要援助那直接参战的部队和作战有效的地方，若作战迟疑、～的部队，必然会成为他们慎重考虑的对象。(《周恩来选集》上—135) They will first send help to those troops that are actually fighting in the war and to those places where fighting is effective,and they will surely think twice before helping troops that arehesitant in battle and divided in purpose.
