难点处理：

1）第三人称单数的判断 除去第一人称 I we 第二人称 you 之外，判断它是否是单个的事物或人物 如果是为单三

外加特例：两不 不可数名词 和 不定代词 2）动词如何变单三 动词变单三和名词变复数基本变法一致 不同点是 以o结尾的变单三直接加+es 不规则的有一 have –has

3)单三的运用 只有在第三人称为主语的肯定句中，动词才用三单式 否定句和疑问句中 关注 助动词 do 的变化 4）句子结构的构成

含有be ,情态动词

否定句 在后加 not

一般疑问句 把 be ,情态动词提前 实意动词

否定句 助动词小do 来帮忙一般疑问句 do/does 提前

特殊疑问句 ：疑问词+一般疑问句 do/does + not
