2 . Over the last few weeks, I have been back and forth to the hospital and working with my doctors and medical technicians. I feel very ________ and appreciative of all the great minds and efforts involved in ________ my illness. I’m very grateful to those human beings who invented the many medical ________ that have saved so many lives.

With everything I ________, I couldn’t help thinking about many life-changing ________ that we humans have come up with, from the fairly simple stethoscope to more ________ inventions like X-rays, and other great devices. Of course, one of the biggest, most basic inventions was the ________. It changed the world in all kinds of ways. Without wheels, we’d have no bikes, cars, trains, or airplanes.

________ many inventions human beings have invented through the ages, I found it ________ to imagine what if we live without some very popular inventions.

Some inventions were accidental ________ but many were matter of simply trying to solve a problem. If we pay attention to what we experience and really put our ________ to it, there is no reason why we couldn’t come up with some new inventions ourselves. Maybe make a list of ________ items, systems, and habits we all have, and then go up and down the list and see if we can put two or three items together in a way to come up with a new ________ or better way to handle life and the ________ in it. Give it a try and see what we can come up with. We could ________ ourselves, and others as well!
