英语 我括号的地方,为什么不用过去式?
Last summer,I went to Italy.I visited museums and sat in public gardens.A friendly watiter taught me a few words of Italian,Then he lent me a book.I read a few lines,but I did (not understand) a word.Every day I thought about my friends.On the last day I made a big decision.I got up early and bought thirty-seven cards.I spent the whole day in my room ,but I did （not write） a single card.

Answer 1

前面助动词do已经用了过去式did 所以后面动词write就不用在变了
