二零二三年 优质公开课Unit2Makingfriends（Grammar）.ppt

Unit 2 Grammar 一般现在时通常可以用于： ? 表示目前阶段经常发生的动作或存在的状态。如： She keeps a diary every day. I enjoy learning about different places in the world. ? 表示客观真理。如： The Sun rises in the east. The Earth goes around the Sun. 一般现在时谓语动词的构成方法如下： ? be 动词的第一人称单数为am，第三人称单数为 is，其余人称为are。 ? 实义动词除主语是第三人称单数外，都用动词原 形；主语是第三人称单数时，在动词词尾加-s 或 -es。have 的第三人称单数形式为has。 ? 在肯定句中，直接用谓语动词的一般现在时形 式。 ? 在否定句中，谓语动词若为be 动词，要变成am/is/are ＋ not ；谓语动词若为实义动词，则要用助动词do/does＋ not ＋实义动词原形。 ? 在一般疑问句中，谓语动词若为be动词，要将is 或are 放在句首；谓语动词若为实义动词，要用 助动词do提问，如主语为第三人称单数，则用 does，同时还要还原实义动词。 动词一般现在时第三人称单数变化规则： ? 通常在动词词尾加-s。如： play→ plays，clean → cleans，visit→ visits。 ? 动词末尾字母以-s、-x、-o、-ch、-sh 结尾的，在 动词后加-es。如： go → goes，mix → mixes，watch→ watches。 ? 以辅音字母加y 结尾的词，先变y为i，再加-es 如：study → studies，carry → carries，hurry → hurries。 We use the simple present tense to talk about regular actions.
