英语忙于干某事是busy doing 还是to do?

忙于做——
be busy doing something
忙于——
be busy with something

get ready for 含有一种行为和动作，意思“为……做好准备”
be ready for只是表示状态，意思“准备好……，为……准备好”

1 be busy doing
2 get ready for 后面加的多为sth.(n.)
而be ready for 后面加的多为动名词（doing)

busy doing
感觉get ready for比be ready for更紧迫

busy doing(读出语感就知道了）
\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/
get ready for 意思“为……做好准备”
be ready for着重于状态，意思“准备好……，为……准备好

be busy doing 忙于某事……
区别在于get 和be，get强调动作，be 就是重在状态了

1.busy doing
2.get ready for中的get是动词，前直接加主语．
3.be ready for中的be需要根据主语而判断，变为am ,ia ,are.
