It was Saturday, and Mindy was getting ready for her twelfth birthday party. In just three 1, all of her friends would arrive with presents and excitement. Every year, Mindy and her mom made a fresh cake on the day of her birthday party. 2, she waited for her mom in the kitchen.
Mindy's mother came into the kitchen and took her apron (围裙) from a hook on the wall. 3 putting it on, she lifted it over Mindy's head.
"Mindy, I think you're 4 enough to make the cake yourself this year. Remember what we say?"
"Yes ... I guess..."
"OK. Now, go ahead and start. I'm going to 5 the balloons." With that, Mindy's mom left Mindy alone in the kitchen.
6, Mindy made the cake herself. Then she put the pan into the oven and set the temperature.
When the cake came out, though, 7 seemed wrong. Mindy tried to stick a toothpick (牙签) into it, just as her mother always did. 8 the toothpick wouldn't go through. The cake was almost as hard as a rock!
"9 is that? I was so careful! I measured（测量）the baking soda exactly," Mindy was very upset. "I did exactly what I was 10 to."
"Baking soda? Oh, dear, that's the 11! You were expected to use baking powder."
Mindy began to 12. "I'm sorry, Mom. I tried so hard."
Mindy's mom gave her a big 13. "I'm the one who is really sorry. I was hard on you and I 14 too much. Now, let's try again. This time, we'll do it together."
"Thank you so much, Mom! Today, I have 15 time to try a second time, but I will." A big smile appeared on Mindy's face.
