发帖数: 1 | 1 上来请教一个问题。。。。
因为种种原因，我很怕跟同事关系搞不好，尤其忌讳被学生扯进去其它同事的纠纷。。
。。最近却偏偏遇到这么一件事情，请教下大家觉得该怎么办？
我一直有一个很能干的grader （T），她跟我做了好几个学期了，我们互相都很适应。
。这学期教的课有一百个人，所以需要2个grader, 就又新找了D。。grader 涉及到5项
任务：
1）每人判50个人的作业；
2）负责解答学生发到邮箱里的问题，因为我一个人忙不过来；
3）跟作业相关的recitation，这个需要准备而且需要去教室讲课;
4）把作业的答案及时上传到网上（solution不用新作，因为题目跟以前的一样）。。。
因为T跟我做了好几个学期了，所以经过大家三人商量后，T自动承担了1-4，D只做1。
。。开始相安无事，直到10月初，T因为找到了工作就辞掉了grader工作，她临走前帮
我找到了N来接替她，她们自己商量好是由D来接管T原来的那些活儿（因为N是新手）。。
没几天功夫，D不愿意回答学生的问题了（2），她没有直接跟我讲，而是在学生问她问

Education, and 80 percent are not grade-level proficient in math.
Chicago public school teachers went on strike on Monday and one of the major

“你不用回答学生的问题了，但其实我是一个很好相处的人跟以前的graders都相处地
不错，如果你直接来跟我说的话，我从来不强人所难，你饶过我去抱怨到复系主任那里
就太严重了”
这段话尺度掌握不是很好。学生想要质疑你对grader职责的理解，系副主任一般管教学
或者研究生事务，她去问，谈不上“太严重”。而且本来就是工作上的事，你不应该说
自己跟以前graders相处如何、从来不强人所难这些话，就按规定来，公事公办就好了。
这个学生显然不是善茬。系副主任有可能对你有意见，也有可能是要息事宁人，和和稀
泥对付过去。
这事儿没什么大不了的，系副主任也不是啥VIP，就算他听信了学生一面之词误会你了
，你也没必要刻意去洗刷自己。放松点儿，接下来该干啥干啥，别纠结。 |

要grader看出你确实明白了，而且没有漏题，就会让你过的。outpost上有一个survey

如果没过，说明两位不同grader都觉得你没过。因为过程是，第一个grader说你过你就
过；如果第一个grader不过，会有第二个再看你的卷子，如果第二个不过你就fail了；
如果第二个过，会有第三个grader再阅一遍，最后这个有最终决定权。
所以所有不过的都是两位grader觉得你不过，我觉得基本上就是你没有真正理解题。

这个适用于打针，做手术，旅行，生妹妹等等重大事件。
胖小第一次看牙医，头一天被老妈告知明天看医生，第二天就上了牙医的椅子。等胖小妈跟其他妈妈聊天，才发现原来小朋友看牙医前可以花几个月讲故事做心理准备……
胖小倒是有一种处乱不惊的态度，从来不为这些应该紧张的事情紧张。
（当然，为了其他本该属于鸡毛蒜皮的小事freak out，是另外一回事。）
八月底的一个星期四，老妈对胖小说：“下个礼拜上学，明天去学校看看。”
这时候离kindergarten开学还有三天。
于是第二天，胖小和老妈orientation去了。
对胖小妈这种不善于适应新事物的人来说，娃娃头一遭上学其实是件很让人紧张的事。疫苗打没打够，表填没填完，after school 怎么去，小朋友在学校怎么吃午饭，老师布置作业娃忘了怎么办？学校寄来的packet才四页纸，老妈觉得四十页也不够。

七月四日，是美国国庆日。在美国居住二十多年，每年看美国的国庆日庆祝活动，都相
当感慨，它至少有两个特色：
首先，美国各地的庆祝活动，不是官方为了宣传国家强大、执政党伟大光荣正确而组织
的，而主要是由民间团体或私人公司举办的。像纽约每年的国庆焰火，都是由梅西（
Macys）百货公司举办的。焰火相当绚丽多彩，据说要几百万美元。而首都华盛顿的焰
火，以及各地的庆祝游行活动等等，几乎都是私人团体举办的。而不像共产国家那样，
从来都是倾国家之力，做政府一手操纵的宣传。
美国国庆纪念活动的第二个特色是，它虽然是纪念国家的建立，但主要是赞美这个国家
保障了每个人的自由，给个人提供了发展的机会，也就是这个国家刚刚建立时发表的《
独立宣言》所确立的那些原则。美国人不说国庆日，而是把七月四日称为“独立日”，
不仅是纪念美国当年从英国统治下争取到独立，建立了一个新的国家，更是传递《独立
宣言》所确立的美国立国精神。这个精神，就是强调人的权利。《独立宣言》译成中文
才二千三百字，其中最重要的内容，是强调人有自由的权利、生命的权利和追求幸福的

随着中国经济的快速增长，能让这个国家一直在动也成了政府的首要任务。在过去几十
