Betty and I are best friends. Our birthdays are on the same day, so every year we have a birthday party together. But this year we had a costume party（化装舞会）______.

While we ______（write）the invitations, my mom came in and asked, “Nancy, what about ______（invite）John?” John came to our class only a few months ago, but he got ______（good）grades in math than anyone else. “Mom, he wears the same pants to school every day. How could he ______（pay）for a costume?” I asked . Mom said nothing.

The ______day, Mom gave me an envelope（信封）with a shopping card in it. “I thought it would be nice of you to give this to John,” Mom said. But how? We didn’t want ______（make）John embarrassed（尴尬的）.We talked about it for a long time. Finally, Betty and I had a good idea.

On the day of our ______, John arrived, still in the same brown pants as usual. Before eating the birthday cake, Betty said, “Now it’s time for the great prize game.”It was a math game. None of us were ______（surprise）when John gave the right answer first and walked off with the envelope.

Everything went just as we planned. John wore a new pair of pants and a new shirt the next week. He ______（feel）happy, and so did we.
