• 主语 + 动词第三人称单数形式 + ... (用于 He, She, It 和单数名词)

动词第三人称单数的变化规则 (核心难点！):

规则	原形	第三人称单数	例句
一般情况直接加 -s	work	works	He works in a hospital.
以 s, x, ch, sh, o 加 -es	watch	watches	She watches TV in the evening. go -> goes
以“辅音字母 + y”变 y 为 i 再加 -es	study	studies	He studies English very hard. fly -> flies
以“元音字母 + y”直接加 -s	play	plays	The boy plays the piano. enjoy -> enjoys
特殊变化	have	has	She has a new bike. do -> does

2. 大声朗读课文: 课文是最好的语料库，通过朗读可以培养语感,熟悉句型结构。
3. 运用时间轴: 画一条从早到晚的时间轴，把你的日常活动用英语标注在上面，然后用 I... at... 或 He/She... at... 的句型来描述。
4. 多造句: 针对每个知识点，自己尝试造句，比如用 usually 造句，用 What time 提问等。
5. 错题整理: 把练习和考试中做错的题整理到错题本上，分析错误原因,定期复习。
