解析：文章讲述Ken的后背疼，住院了，医生向他妻子介绍他的病情。
【小题1】肯的后背疼，所以他住院了，be in hospital“生病住院”。去掉the
【小题2】医生和肯的妻子谈论他的状况，这里的他指“Ken”，her改成his
【小题3】当她问到她丈夫的背疼有多严重的时候。修饰形容词serious，用how
【小题4】医生说Ken要完全卧床休息。Completely是副词，修饰形容词或动词，而修饰bed rest 用plete
【小题5】这意味着他回家前要躺两到三个星期。这篇文章是叙述过去的事情，用一般过去式：has改成had
【小题6】从后面的句子：He then had to stay bed for about 10 days.可知他是回家前在医院要一直躺着。after改成before
【小题7】回家后，他要卧床10天。stay改成in
【小题8】他只能一天起来两次活动10分钟。Could后面接动词原形：got改成get
【小题9】10分钟，用10 minutes
