【答案解析】[听力原文]17-20
Jada and Jessie are twins. They were born on August 5, 1992. They are ten now and in the fourth grade. Jada and Jessie do everything together. They are in the same class. They dress alike. They look the same. People always get them confused. This really makes Jada and Jessie laugh. Teachers always get them mixed up at school. Even their father has trouble telling them apart. Their mother doesn't, though. She always knows which twin is which. Jada and Jessie often try to confuse her, but it has never happened.
Their older brother, Jared, is fifteen. He never knows which one is which. He doesn't even try. Jada and Jessie have the same friends. Their friends always mix them up. It doesn't matter to Jada and Jessie.
One day, their father told their mother to get one of them a different haircut, so that he could tell them apart. Jada and Jessie were horrified. They didn't want to look different. They liked looking the same. Their mother came to the rescue, and refused to make them cut their hair. The girls were happy just the way they were and didn't want to change. Their dad just shook his head. He would have to stay confused. Jada and Jessie didn't care. They knew which one was which, and that was all that mattered.
