本题考查一般过去时的应用，一般过去时用于描述过去发生的动作或存在的状态，句中常出现过去时间标志，并列谓语的时态需保持一致，谓语动词要使用对应的过去式：
1. 句中出现过去时间状语last week，且and后的并列动词learned为过去式，因此visit要变为过去式visited。
2. 句中and后的并列动词told为过去式，说明动作发生在过去，show要变为过去式showed。
3. 第一空at first表示过去的时间，主语为I，一般过去时的否定结构为“didn't + 动词原形”，因此填didn't like；第二空描述之后过去发生的转变，become的过去式为became。
4. 该句描述过去发生的两个先后动作，两个动词都要变为过去式，get的过去式是got，start的过去式是started。
5. 句中and后的并列动词tasted为过去式，说明动作发生在过去，try的过去式是tried。

B. 请描述你曾经参加的一项活动，完成表格。

Where did you go? I went to the Green Farm with my friends last July.
What did you do/see? We picked vegetables, milked a cow and saw lots of lovely animals on the farm.
How did you feel? I felt quite happy and relaxed that day.
What did you learn? I learned that it is not easy for farmers to grow food, and we should never waste food.

这是一道开放性表达题，考查一般过去时的运用能力，要求学生结合自身经历描述曾经参与的活动，答案不唯一，使用符合七年级难度的简单句式、正确使用动词过去式即可。
