1. 主语We为复数，be动词用were，“看电视”用watch TV的现在分词形式watching；具体时刻前用介词at。
2. 主语I对应的be动词是was，“做家庭作业”是do one's homework，do的现在分词为doing。
3. 主语they为复数，be动词用were，“步行穿过森林”是walk through the forest，walk的现在分词为walking。
4. “听音乐”是固定短语listen to music，主语I对应的be动词是was，listen的现在分词为listening。
5. 主语he对应的be动词是was，“打篮球”是play basketball，play的现在分词为playing。
