“陈述句改否定句怎么改”的回答:
陈述句改否定句通常有以下几种方法:
1. 有 be 动词(am/is/are/was/were)的句子,在 be 动词后加“not”。例如:“She is a teacher.” 改为否定句为 “She is not a teacher.”
2. 有情态动词(can/could/may/might/must/should/ought to 等)的句子,在情态动词后加“not”。比如:“He can swim.” 改否定句为 “He can not swim.” 或者“He can't swim.”
3. 没有 be 动词和情态动词的句子,要借助助动词(do/does/did),并在助动词后加“not”。同时,原句中的动词要变回原形。例如:“She likes apples.” 改为否定句是 “She does not like apples.” 或者“She doesn't like apples.”
需要注意的是,改否定句时要注意保持句子的原意和语法结构的正确。同时,缩写形式(如 isn't, aren't, don't, doesn't 等)在日常使用中较为常见,但在正式书写中可能更倾向于使用完整形式(is not, are not, do not, does not )。
希望这些方法能帮助您将陈述句成功改为否定句!
