要是汉老师太想当最后一个发言的，下次先打个招呼，善和就不说了，否则会傻呼呼地跟贴，以为别人和我想的一样，因为欢迎他人是最后一个， 那样可以学到更多 :)) 别见怪啊，喜欢汉老师脾气中的傲气，只是有时冒犯了 :))
Brook， creek 特指溪流， stream 不是的。 也可能是你认为的 "一般", 并不是美国人和字典中的 "一般 "，要看谈话内容， 可指 a large body of running water or small ones, depending on the context,范围比较广，正适合此处画卷的内涵.
A stream is a body of water [1] with a current, confined within a bed and stream banks. Depending on its locale or certain characteristics, a stream may be referred to as a branch, brook, beck, burn, creek, "crick", gill (occasionally ghyll), kill, lick, mill race, rill, river, syke, bayou, rivulet, streamage, wash, run or runnel.
