行为动词 系动词改成 didn't do be动词改为wasn't/weren't 情态动词 couldn't shouldn't等 加 not no的话 额 比如 We had some fruits yesterday We had no fruits yesterday. no=not any 所以又可以是We didn't had any fruits yesterday 看具体情况
(1)There is no computer on the table. 桌上没有电脑。 (2)There are not many books on the bookshelves. 书架上没有多少书。 (1)中的no可以变成not 吗? (2)中的not可以变成no吗? 选no还是not是不是要看主语的单复形式? 谢谢!
这是过去式么 no=not any 所以1可以改为 There are not any computers on the table 2 There are no books on the bookshelves (no作形容词 把many去掉) 特别地 a lot of 用于肯定句 否定句改为 many或much no后面既可以加单数也可以加复数 主语的单复形式只决定be动词 is am are等 但there be中 be动词后的第一个名词单复数决定be动词的单复数形式
