All year, Terrific Kids celebrated their special days in special ways, but Tiffany hoped her turn would never come.
When Benjamin was the Terrific Kid, his aunt Sarah taught the class how to draw funny cartoon faces. When Kewin was the Terrific Kid, his twin baby sisters came to school. Tiffany didn’t have an aunt who draw cartoons, and she didn’t have any friends at all.
After school, Tiffany walked to the school library for Story Hour. Mrs. Kaplan, a librarian, greeted Tiffany with a bright smile.
After Story Hour, Tiffany’s mother came to the school to pick her up. “We’ll stop at Tico Tony’s tonight,” her mother said.
“Great!” Tiffany replied. Tico Tony’s tacos were Tiffany’s favorite. Tiffany and her mother ate their tacos at a window table.
After dinner, as Tiffany and her mother arrived at their building, Mrs. Washington waved from the apartment next door. Sometimes Tiffany pretended that Mrs. Washington was her real grandmother.
Finally, Tiffany’s turn came. That day, Tiffany went to school with her mother. When they got to her classroom,

In your school, are you allowed to choose the subjects you want to learn? Of course, the answer is “No” here in China. In America there is a school trying something new. At a high school in Florida, students will be able to choose their own classes. We all know that some students are better at some subjects than others, Some students plan to go on to college, while others will not. At this school students are able to find subjects they are interested in,
and possibly even find the field (领域) they would like to go into after school. They are allowed to choose a subject
like biology, math, a foreign language, or study skills like computer or car repair. Some people think this is a good idea, because it helps students think about what they want to do in the future, and the school helps to give them the knowledge and skills needed to get there. They say that giving the students the chance to choose their own classes makes high school more interesting. Others disagree. They think it will make it difficult for students to discover
different possibilities (潜力). They point out that fourteen-year-old teenagers are too young to know what they will
want to do in the future. What do you think? Would you like to be able to choose your own classes? Many useful changes have been made in education, but seeing the differences in each student is also important. How can we help each student become a better student?
