She is a student. 客观真理：The Earth goes around the Sun. 常用时间状语： always, usually, often, sometimes, seldom (频率副词) every day/week/morning... on Sundays, in the morning once a week (一周一次) 二、句型结构详解（重点：第三人称单数） A. 含Be动词的句子 结构：主语 + am/is/are + 其他（表语）。 I → am He/She/It/单数名词 → is You/We/They/复数名词 → are 句式 结构 例句 肯定句 主 + be + ... She is happy. 否定句 主 + be + not + ... She is not (isn’t) happy. 疑问句 Be + 主 + ... Is she happy B. 含实义动词的句子（核心难点） 黄金规则：当主语是第三人称单数（He, She, It, 单个人名如Mike） 时，谓语动词要变成三单形式。 1. 动词三单形式变化规则： 规则 原形 三单形式 例句 一般加 -s like, play, swim likes, plays, swims He likes music. 以 ch, sh, s, x, o 结尾，加 -es watch, wash, guess, fix, do watches, washes, guesses, fixes, does She watches TV. 以 辅音字母+y 结尾，变y为i再加-es study, carry, fly studies, carries, flies Tom studies hard. 特殊变化 have has My father has a car. 2. 句式结构： 句式 主语非三单 (I/You/We/They) 主语是三单 (He/She/It) 肯定句 主 + 动词原形 + ... 主 + 动词三单 + ... We play football. He plays football. 否定句 主 + don‘t + 动词原形 + ... 主 + doesn’t + 动词原形 + ... We don‘t play football. He doesn‘t play football. (动词还原！) 一般疑问句 Do + 主 + 动词原形 + ... Does + 主 + 动词原形 + ... Do you play football Does he play football (动词还原！) 回答 Yes, I/we/they do. No, ... don‘t. Yes, he/she/it does. No, ... doesn‘t. 核心易错点警示： 在否定句（doesn’t）和疑问句（Does...）中，后面的动词必须打回原形！ She doesn’t likes music. Does he goes to school She doesn’t like music.
