On their way back, Henry saw some flowers. He liked flowers very much and ran into the green field to look at them. Now Allan was walking by himself.

Then he heard Henry calling out, “A snake! Help!…”

“What’s wrong with you?” asked Allan.

“A snake bit（咬）me in the leg. Come here!”

Allan ran over and saw a small red wound on Henry’s leg.

“The snake was in the grass. I didn’t see it.”

“Sit down quickly!” Allan told Henry.
