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。

常见活动与地点词汇:go on vacation, visit museumsgo to the beachgo to the mountainsstay at homego shopping

: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)。
