改错题He wrote a letter to his father last night,but I don't know whether he has finished it答案是将wrote改为was wirting.为什么呀 he wrote a letter to me last year.对wrote a letter to me 划线提问 that night he wrote a letter to a newspaper. He wrote a letter last night.改为一般否定句 he wrote a letter to his friend改为否定句 He wrote a letter of ________ (invite) to his friends. wrote he a yesterday letter 连词成句 he wrote a letter in pencil,为什么用in he wrote a letter just now .的同义句. i wrote a letter.passive He wrote a letter to his friend yesterday.(改为一般问句)________ he _____a letter to is friend yesterday? for three years ,But he is a shy boy ,so i wrote hum a letter firstly 高一英语改错题第一题：He rushed to help the man his car was trapped in the mud.第二题：Do you know the man wrote the letter?第三题：This is all the money with that he can buy a Christmas present for his mother.以上三题都有错 Last night he wrote a ( ) letter to his friend.填100-word 还是 100 words 一般将来时和一般过去时He will go swimming tomorrowI wrote a letter to my mother on yesterday Nine years later he wrote in a letter.Nine years later算是什么? 是状语吗?
