Wei Hua had a busy day yesterday. She got up before 7 o'clock in the morning, and quickly washed her hands and face. She got to school early. She had a little rest after lunch, but worked hard in class all day. She played basketball after school, and then she walked home. Wei Hua's pen was broken, so she needed a new one. On her way home she bought a new pen at a shop. When she reached home, she had a short rest and a glass of water. After that she helped her parents. She quickly cooked the supper, and cleaned the house. She watched TV for half an hour after supper. Then she started her homework. She finished it at half past nine. She went to bed before a quarter to ten. What did she buy on her way home?
A book. Some food. Some drinks. A pen
