（A）

It was the first day of rehearsal (排练). Mary was nervous. The first student read the lines (台词) like a movie star. This made Mary more nervous. Her voice was shaking when she read her lines.

Coming back home, Mary told dad that the rehearsal didn't go well. “Don't worry. Relax and you'll do fine,” dad said. At that time, Mary's dog Snoopy was looking up at them. “You can read to your dog,” advised dad. “Ruff, Ruff,” barked Snoopy.

Since then, Mary read to her dog to practice the lines every day after school. In the following rehearsals, she felt much better.

Finally, the night of the school play arrived. The curtain (幕布) opened, and Mary saw dad in the audience. She didn't feel nervous at all. Her lines came out easily, just as if she were reading to Snoopy. The play was a great success.
