不多于吗? 原文是
Postcards always spoil my holidays. Last summer, I went to Italy. I visited museums and sat in public gardens. A friendly waiter 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 postcards. My holidays passed quickly, but I did not send cards to 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!
然后他给了我一本书, 我读了几行, 但是我一个字都不懂.
首先,这是叙述过去发生的事情.
时态都用的过去式.
I did not understand a word.
为什么要加did呢, 因为否定的是understand这个词, 而且是发生在过去的,不懂,而不是懂, 所以要用did not.
问: i did understand a word 这样的话,did可以去掉吗?如果不去掉,起什么作用?
答: did可以去掉, understand要变understood. 不去掉的话, did起语气强调作用,
那直接把understand改为understood不就可以吗?
追答I did not understand a word. 因为有助动词 did, 后面要跟动词原形,所以understand 是不能用过去时的。
追问我就是想知道为什么要用助动词,不用助动词不也能表示过去吗?
追答understood 在语法上是正确的,但是在本句中不符合句意,这个句子的意思是否定的,句子变否定时,要加助动词。
追问哦 ,那比如我把这句话改为肯定句, i did understand a word 这样的话,did可以去掉吗?如果不去掉,起什么作用?
追答如果是肯定句的话,就无需加助动词did了,因为是过去时,understand变为 understood, I understood a word.
追问那加did是不是表示肯定?
追答加 did 可以表示强调,加强语气。“我确实理解一个词的意思。”
追问加我,我采纳好吗?
追答O(∩_∩)O可以
