Answer 1

【答案】1. were 2. listened 3. am doing 4. touch 5. goes

【解析】

1. 根据时间标志词a moment ago可知句子用一般过去时，主语是they，所以be动词用were.

2. 根据时间标志词last week可知句子用一般过去时，所以listen用过去式listened.

3. 根据时间标志词now可知句子用现在进行时，主语是I，所以空处应填am doing.

4. 祈使句中动词用原形，所以空处填touch.

5. 根据时间标志词often, on Sundays可知句子用一般现在时，主语是my father，所以go用单三形式，即goes.
