General Discussion - 把 （介）need examples, please!?

Hello everybody,

i bought a new exercise book yesterday, with several sentance build, use vocab, find mistakes in chinese sentances, write character...exercises.

In one of these sentances 把 ba3 was used as a measure word, and then there was a note that there is another use for 把:

"used when the object goes before the verb, which must be reduplicated or accompanied by some other word or expression"

I never had this before, i think, and i dont really understand the explanation... 

Can anybody help me with examples and explanations or link me to a cPod lesson where it is used like this? i couldnt find one by now.. 

thanks, 格桑
