He often __(help)his mother___(clean )the house. He __(live)in a small city .填空详解谢谢 90

He often 【helps 】(help)his mother【clean / to clean 】(clean )the house.He 【lives 】(live)in a small city .
often 经常,这是个一般现在时的句子,主语是 he第三人称单数,所以动词也用三单：helps,lives,由句型：help sb.( to ) do sth.可知：第2个空填写：( to ) clean.
翻译：他经常帮母亲打扫房子,他住在一个小城市.
不明白的再问哟,请及时采纳,多谢!
