canal, branch, brook, creek, river, stream, torrent: 这组词的共同意思是“流水的通道”。其区别是：
1.除canal指人工开挖的河流或渠道外，其余各词均指自然形成的水道。
2.river和torrent均指流量较大的河流，river可泛指(自然形成的)江河；torrent则特指急流、湍流。这两个词还常用于比喻。
3.stream可指大河，也可指小河或小溪，指小溪时与brook,creek同义。creek侧重其狭长蜿蜒，缓缓流动，且多流入大河或湖泊。brook侧重发源于山泉。creek和stream都比brook大。stream还可引申表示事物连绵不断。
4.branch指江河的支流。
