学习前建议

心态转变：从七年级的“是什么”转变为“为什么”，理解语法背后的逻辑。

系统梳理：八年级语法呈体系化出现（如时态、句子成分），需要定期归纳总结。

重在应用：将所学语法和句型尝试用于造句、写作中，实现从输入到输出的转化。

Unit 1 Where did you go on vacation?

：主语 + 动词的过去式 + 其他。

did not (didn't) + 动词原形 + 其他。 (be动词除外：was/were + not

一般疑问句Did + 主语 + 动词原形 + 其他？ (Was/Were + 主语 + 其他？)

关键：熟记规则动词（+ed）和不规则动词的过去式（如 go→went, see→saw, do→did, have→had）。

用括号内动词的过去式填空：
