英语翻译As we shall see ,the practice of housing the psychologic

这句句子中的第二个with后面应当有一个解词宾语,由于原句为被动语态,其宾语是句子的主语了"the practice of ...".不妨还原原句（需要加一个主语）："As we shall see,we are experimenting with the practice of housing the psychologically disabled with the willing families in the United States today." 这样,对你理解有所帮助.
...experiment with ...是指：“用XX进行试验/实验”“对XX进行试验/实验”.
