---Your sister nearly _______ all her spare time to her study during the three years. ----That's right， or she ________ the first place in her school in the College Entrance Examination. 

I insisted that a doctor ________ immediately.

Has it been warned that all the children in this area      stay at their homes until the Flu has been controlled ?

Though it is the first time they have met, they talked as if they _____ friends for many years.

It is difficult, so I suggest that you       __ it to an expert.
