1. B
2. A
3. C
4. B

1. 从Elain的短文内容中找到"Her work starts at 10:00 p. m."，可知Elain的妈妈晚上10点开始工作，对应选项B。
2. 文中提到Elain的妈妈在医院工作，结合"looks after each patient"的语境，在医院工作需要照料的对象是病人，所以"patient"的中文意思是病人，对应选项A。
3. 从Bob的短文内容中找到"We know he needs a lot of sleep. So we try to be quiet at night."，可知Bob家人晚上保持安静是因为爸爸需要充足的睡眠，对应选项C。
4. 选项A：Elain的妈妈晚上10点开始工作，次日早上8点停止工作，一共工作10小时，不是9小时，表述错误；选项B：短文标注了"By:Bob Wang on 10th November 7:30 p. m."，说明Bob是在11月10日写的这篇帖子，表述正确；选项C：文中只提到妈妈不忙的时候Elain会和妈妈去公园，并没有说明是每周末，表述错误。所以选B。
