There was no umbrella in her hands. She seemed to be afraid of the heavy rain and didn’t know ______ to do at that time. It was very ______ for her to stay under the big tree. I took two umbrellas and rushed out of my house. When I gave her an umbrella, I found she was my neighbor. ______ I didn’t know what her name was.
