阅读下面短文，回答下列五道题。 ①“人之患在好为人师”，变为成语就是四个字“好为人师”，用以批评那些不谦虚，喜欢以教育别人姿态出现的人。 ②其实，在不少情况下，“好为人师”并不错。“闻道有先后，术业有专攻”，如果你的知识比某人多，经验比人家丰富，在别人需要的情况下，给别人作些知识传授或经验介绍，不是应当称颂的吗 ③一个人长了嘴巴，不说话就是“失职”，遇到别人在认识上有缺陷或错误时，能抱着同志式的热忱，给以教育和帮助，是应当提倡的。比如，你看见人家写错了字，告诉他一声，这个字应当怎样写，这样“好为人师”，人家是欢迎的。 ④另一种立意，可以把“师”理解成“教师”，教师本是“太阳底下最光辉的事业”，但是，有些人在经济大潮冲击下，加之旧的传统观念影响，多不愿当老师，而那些有志于教育事业的青年人，“好为人师”，则是应当受到鼓励的。全国特级教师魏书生本是一名工人，为了实现自己的愿望，一共向各级政府部门打了二十几份申请报告。近年来，有的地方在高考时，师范院校提前招生，有的地方在高校录取时，师范院校降档录取，无疑都是在鼓励考生“好为人师”。 ⑤还可以将“好”的意思理解为努力、认真的意思。即，要好好地当个人民教师。教师担负着教育下一代的重任，必须全身心地投入，但是，由于种种原因造成了教师待遇低，社会地位不高，使得一部分教师跳槽改行，“下海”经商，另一部分教师人在课堂，心在市场，以本职工作为副，以第二职业为主，使得教育工作受到了不良的影响，这是应当否定的。一方面，有关部门要关心教师，使之“好为人师”；另一方面，当教师的要立足本职，当好教师，不能误人子弟。 本文中作者对“好为人师”的“师”的解释是______。

In the United States the cost of living has been steadily rising for the past few decades. Food prices, clothing costs, housing expenses, and tuition fees are (36) getting higher and higher.

Some (42) are obvious. For example, dinnertime is at a later hour. Mothers leave home early in the morning, feeling (43) because they will not be at home when their children return from school. They suppress their guilt since they believe that their work will benefit everyone in the long run. (44) . The emotional impact on the children can be significant. After all, they are alone for several hours during the daytime, and they feel that their mothers should be there for them. (45) . All too often, however, the mothers arrive home exhausted and face the immediate task of preparing dinner for the family. (46) .
