复习一（第1–5课）
标注的核心时长。核心模块中有两项未标注时长，因此实际课时比总和更长。
不规则动词
4 分钟新学十个，每个都有三种形式：
| burn — burnt — burnt（烧，燃烧） | dig — dug — dug（挖） | fight — fought — fought（打架，斗争） |
| choose — chose — chosen（选择） | fall — fell — fallen（落下，摔倒） | forget — forgot — forgotten（忘记） |
| lead — led — led（带领） | spread — spread — spread（传播，涂抹） | stick — stuck — stuck（粘贴，卡住） |
| wear — wore — worn（穿，戴） |
难点
3 分钟ago 和 for：都和时间有关，回答的却是不同的问题。
| I came here five years ago. | 什么时候？——五年前。一般过去时。 |
| I've lived here for five years. | 多长时间？——五年。现在完成时。 |
ago 总是放在一段时间的后面，而且总是和一般过去时连用。for 放在一段时间的前面，动作还在继续时和完成时连用。
同一件事，两种说法：I started this job two years ago = I've worked here for two years。

小结
本课已学：第1–5课全部内容，到目前为止共五十个不规则动词。下一课——第7课：比较两样东西。
核心内容结束
完成练习后即视为课程结束。此后的内容均为可选。
可选
小型产出
口头讲一讲，再写下来——八个句子：上个周末做了什么，昨天晚上当时正在发生什么，今天已经做完了什么，你去过哪里，以及你在自己的城市住了多久。
学第7课之前的检查清单：
- did 和 didn't 后面的动词用的是原形吗？
- have 和 has 后面用的是第三种形式吗？
- 完成时的句子里没有说出具体时间吧？
- for 后面是一段时间，since 后面是起点，ago 放在一段时间后面、和过去时连用吗？
- 背景用 was/were + -ing，事件用一般过去时了吗？
