stop

1.stop后面接不定式作“停下来而…”解，就是“停止了其他动作而从事于…”，stop是不及物动词。stop后面接动名词作“停止…”解，stop是及物动词。如He stopped to consider it是“他停下来而考虑它”。He stopped considering it是“他停止考虑它。”参见cease

2.下面三句意思相同，但第三句不算正当：

• We cannot stop him from coming.
• We cannot stop his coming.
• We cannot stop him coming.

3.Where are you stopping? He stopped with a friend last night等句子里的stopping和stopped多少有些口语性质，在文字里该改作staying和stayed。

4.stop off（中途下车）或stop over是美国英语，相当于英国英语break his（或your等）journey。stop by（访问）或stop in也是美国英语。
