1.where is bob?---he ___the violin in his bedroom now.2.sometimes i ___some newspapers in the evening.3.jim,let's___the room now.---but i ___my homework.4.is kate doing her homework?---no.she ___a letter to her pen pal.5.she isn't reading.she ___ a song.

答案

1.is playing （now表明是现在进行时）
2.read （sometimes是一般现在时的时间状语）
3.clean am doing（let's后接动词原形,now表示现在,but表示转折,现在不能做说明正在做别的事,所以后一个空填现在进行时）
4.is writing（is kate doing her homework?是现在进行时,所以用现在进行时回答）
5.is singing（前一句为现在进行时,根据句意,后一句与前一句时态相同,也用现在进行时）
