考点1.    表伴随还是表目的
The secretary worked all night long,____ along speech for the president.
A.to prepare    B.preparing  
C.prepared     D.was preparing
许多同学会选择A,认为目的是“为了准备演讲稿”.这说明概念还不清.
现在分词表伴随时,其动作和谓语动作是同时进行的.而动词不定式作目的状语时,通常译作“为了”,为了达到不定式所表达的目的,先做句子谓语的动作.也就是说,两个动作有先后,先有谓语动作,后有动词不定式的动作.
She got up early that morning to get thereon time.(先早起,后按时到达)
He works very hard to catch up with others.(先努力学习,后赶上别人)
而在上题中,整夜工作和准备演讲稿是同时进行的,因此选择B,现在分词.如果选择A的话,便容易误解为“先工作了一整夜,然后才准备演讲稿
