英语有一般疑问句、否定句、肯定句还有什么还有
祈使句、陈述句、
宾语从句、定语从句和表语从句等。
疑问句:含有行为动词的句子(如like,have,play,eat,run,need等)时,要分两步看主语。
①I / We / You / They 时,要借助于
助动词do的帮助来变成一般疑问句。即句型为:
Do + 主语 + 动词原形 + 其他?
②He / She / It 时, 要借助于助动词does的帮助来变成一般疑问句。即句型为:
Does + 主语 + 动词原形 + 其他?
肯定句变否定句的方法
如果肯定句是特殊句型,则要具体问题具体分析:
陈述句中含有had better时,变为否定句时,要把not加在better后。例如:
You had better go with me.
You had better not go with me.
陈述句中含有both (all) of +名词作主语时,改为否定句时,要用neither来代替both,none代替all。并注意
谓语动词数的变化。例如:
Both of them are Americans.
Neither of them is American.
