【分析】
解决本题的关键是先通过句子中的时间状语判断时态为一般过去时，再将对应内容调整为过去式形式：1-4小题需根据时间状语把括号内动词变为过去式，第5小题是汉译英，需对应“做某事很开心”的固定短语并调整为过去式。
【解析】
1. 时间状语“two weeks ago（两周前）”是一般过去时标志，join的过去式为joined；
2. 时间状语“last year（去年）”的“every day”表示过去经常性动作，用一般过去时，practise的过去式为practised；
3. “This morning（今天早上）”是过去时间，use的过去式为used；
4. 后半句“didn't help”为过去式，try的过去式为tried；
5. “两天前”对应一般过去时，“做某事很开心”的固定表达为be happy to do，主语Sandy是单数，过去式be动词用was，“收到”用get，故填was happy to get。
【答案】
1. joined
2. practised
3. used
4. tried
5. was happy to get
