用所给单词的适当形式填空。
1. The (woman) are singing happily in the park.
2. Look, they (sing) and (dance).
3. Can Betty (play) the piano?
4. The boys (sing) songs now.
5. He's riding his bike, but it (start) to rain.
6. Tom is writing his homework, but his father (come) back.

1. women 2. are singing; dancing 3. play 4. are singing 5. starts 6. comes

1. 句中be动词为are，说明主语是复数，可数名词woman的复数形式为women。
2. 提示词Look是现在进行时的典型标志，现在进行时结构为"主语+be动词+动词现在分词"，主语是they，be动词用are；and连接并列的谓语动词，形式保持一致，所以sing变为are singing，dance变为dancing。
3. 情态动词can后面必须接动词原形，所以直接填play。
4. 句中now是现在进行时的标志，主语the boys是复数，be动词用are，sing的现在分词为singing，所以填are singing。
5. 前半句用现在进行时描述正在进行的动作，but后描述突然插入的客观动作，主语it是第三人称单数，谓语动词用第三人称单数形式starts。
6. 前半句描述Tom正在做的事，but后描述突然发生的动作，主语his father是第三人称单数，谓语动词用第三人称单数形式comes。
