tend: suggests the need for constant or recurring attention: a shepherd ~ing his flock.       （tend照看照料to give attention to, take care of，又如please tend the store while I'm away我不在时请照看店铺，如well-tended gardens照料良好的花园，tending his business照料他的生意）    照看羊群的牧羊人


attend: is more likely to stress a taking charge and is, therefore, appropriate when a professional service or skilled activity is involved: the doctor who ~ed his mother.  （take charge of主管负责，如he is in charge of the school work他负责学校工作） 又如each nurse attends 15 patients每位护士照料15位病人  本例doctor和his应是两个人  professional专业的，使用较随意，我们不对professional作辨析

mind: otherwise close to tend, distinctively suggests a guarding or protecting from injury or harm or failure: a neighbor who ~s their children after school.    又如who is minding the children/office谁在照看(照料照顾)小孩/办公室？   guard保安保镖表示时刻警惕的保护implies a protecting with vigilance and force against expected danger，如guard the White House为白宫提供安保，如body guard保镖


watch: often close to mind, may imply a more constant or more professional relationship or suggest an actual need to forestall danger: a guard hired to ~ the store at night.    （forestall预先阻止先发制人to prevent in advance, 如谚语to forestall is better than to amend其补救于已然，不如防患于未然=prevention is better than cure）  如派生词watchful警觉的，如played under the watchful eyes of their mothers在母亲警觉的双眼下玩耍；如美国总统说不会允许某事在自己眼皮底下发生under his watch


tend照看照料: 表示持续关注照料，attend也是照看照料: 但强调负责，具有专业技术，mind也是照看照料: 表示看守保护，防止意外伤害，watch看守: 同上，更警惕，也更专业
