Unfortunately, I don't think a drug test would be helpful at this point.

What additional diagnostic tests would be helpful at this time, and why?

It might be helpful at this point to consider how the opera as a whole works along comparable lines.

It is helpful at this point to introduce some examples of real speech.

It would be helpful to state this clearly at the highest level and work out a strategy to match the vision.

My training as a surgeon was very helpful at that point.

Medical equipment such as a wheelchair, walker, and hospital bed can be very helpful at this time.

I talked to my doctor, of course, but he wasn't very helpful at all.

There has been talk of forming a support group that might be helpful at the present stage.

It might be helpful at these times to have more staff available and less at others.
