Her cap fell off in the street and blew away .
When she said she was engaged I nearly fell off my chair.
动副组合,当一个原的动词来看;动介词的组合是按动词与介词的关密组合新的动词吗,如果关系不密切,就是动状结构?
判断方法:
fall off + 无宾语:off 为副词
fall off + 有宾语:off 为介词
【注意】以上fall 为不及物动词。第一个例句是“动副组合”,你的第二个例句,是“动介组合”。差别就是:off 是否接宾语。
如果是及物动词,小品词off 就是副词,而不是介词,无论宾语在什么位置。例如:
cut off the branch (切下枝条)
这时,还可说:cut the branch off

fall off=为一个不及物短语动词用法 意思为 ”脱落,掉落“
When she said she was engaged I nearly fell off my chair
fall off +名词,属于 及物短语动词用法,

动词+虚词(副词/介词)构成的“短语动词有以下几种:
(1)动词+副词
A:短语及物动词 后面能接宾语,其宾语为名词,可以放在后面,也可以放在中间,如宾语为代词,只能放在中间。
put on=动词+副词构成及物短语动词,后可以接宾语。
He put on his coat and went out.
=He put his coat on and went out.
他穿上大衣出去了。
Can I try them on?(宾语为代词,只能放在动词和副词中间)
我可以试穿它们吗?
B:短语不及物动词:后面不能接宾语/没有宾语。
break out =动词+副词 构成不及物短语动词,后不能接宾语。
He was 29 when war broke out.
战争爆发时他才29岁。
I was in a nightclub in Brixton and a fight broke out.
当时我在布里克斯顿的一家夜总会里,那里发生了一场斗殴。
(2)动词+介词:其宾语只能放在后面。

Her cap fell off in the street and blew away . 此句中的fall off属于“动词+副词”型短语,后面不接宾语,意思是“掉落”。
When she said she was engaged I nearly fell off my chair. 此句中的fall off属于“动词+介词”型短语,后面接宾语,意思是“从......掉落;从......落下来”。
但是,有些“动词+副词”型短语必须带宾语。例如:put on his coat = put his coat on ,这里的 put on 是“动词+副词”型短语,his coat 是宾语。
