stream 和 flow 在做动词时有什么区别.
做完形填空的时候做到的.不知道怎么去区分.

pour,flow,run,stream
这组词的共同意思是“流”“流动”.其区别是：
1.flow,run,stream和pour都可指液体流动; flow还可指气体流动; pour还可指光线、微粒等倾泻.
2.时间上:flow一般指源源不断地、长时间地流动; run既可以是源源不断地、长时间地流动,也可以是流动一段时间; stream和pour多指短时间地流动.
3.方向上:指液体流动时,flow是水平流动; run和stream既可水平流动,也可垂直流动; pour是垂直流动.
4.流速上:从快到慢依次为pour,stream,run,flow.具体说就是flow是平平稳稳地流动; run比较湍急; stream比run更有力; pour则是“倾泻”.
5.flow,stream和pour常用于比喻,run很少用于比喻.例如:
The river was flowing quietly.河水静静流着.
She let her hair down so that it flew darkly over her shoulders.她让乌黑的头发披散下来,飘垂到肩上.
The river runs through hills and fields.河水流经山冈和田野.
The water runs out of the pipe into the bucket.水自管内注入水桶中.
Tears were streaming down her face.她脸上热泪滚滚而下.
The students streamed into the auditorium.学生们络绎不绝地进入礼堂.
下面三句话的意思相同:
She poured me a cup of tea.
She poured a cup of tea for me.
She poured me out a cup of tea.
她给我倒了一杯茶.
