1.（Were） you at home yesterday evening?（at home是副词短语,需要与be动词连用）
2.We （wrote） an article yesterday morning.（write的过去式为wrote）
3.He was hungry ,so he (stopped) to have dinner.（stop的过去式为stopped）
4.(Did) you go to school yesterday?（因为go是实意动词,要借助助动词do/does/did提问）
5.---Were you at school yesterday morning?
---Yes,I （was）.(am的过去式为was)
6.（Are）you afraid of strange animals?（afraid“害怕的”为形容词,所以要be动词作谓语）
