1) 由"Yesterday"可知用一般过去时，"watch TV"的过去式是"watched"。
2) "吃冰淇淋"用"eat"，过去式为"ate"。
3) "买新书"用"buy"，过去式为"bought"。
4) 否定回答后接过去式，"listen to music"的过去式是"listened"。
5) "去动物园"原句用"go"，否定回答用过去式"went"（此处结合插图推测为步行，即"walked"，但根据五年级上册Module 1重点，"go"的过去式是"went"，若插图显示步行则填"walked"，此处按常规逻辑及模块重点暂填"went"，实际需结合插图确认，若插图为步行则修正为"walked"）。
6) 否定回答后接过去式，"读书"用"read"（过去式同原形）。
