衔毒草喂子金翅雀爸爸叼着小虫子又来了，它回到自家窝边，窝里静悄悄的。
就在它出去觅食的工夫，小鸟不知让哪个恶棍掏走了。
它哭着叫着寻找失踪的孩子，森林里充满了它的悲衷的啼叫声和呼唤声，可是什么回音也没有。
金翅雀爸爸伤透了心，第二天清晨，苍头燕雀碰见它说，昨天在一个农夫家里看见了它的孩子们。
金翅雀爸爸喜出望外，它奋力向村子飞去，很快飞到苍头燕雀说的那家农舍。
它敛翅歇在房顶马头形的檐角上，举目张望，不见小鸟的动静，它掠翅飞向打谷场，场地上空空荡荡。
可怜的父亲一仰头看见了悬挂在屋檐小窗口的鸟笼，里边蜷伏着成了俘虏的幼儿。
它猛冲过去。
小鸟也认出了父亲，它们隔着笼子，一起吱吱喳喳诉起苦来，小鸟央求父亲快些把它们解救出去。
金翅雀爸爸用它的脚爪，用它的尖喙（huì），狠命地扯啄着鸟笼上的铁丝，泣血挣扎想把铁丝拉开，却是枉然。
极度哀伤的金翅雀爸爸挨过了一个晚上，第二天，它飞回到自己孩子在里边受苦的鸟笼边，它用温柔的目光久久地注视着孩子们，然后在每只小鸟张开的嘴巴里轻轻地啄了一下。

由分析可知，用它煎3张饼最少需要3分钟。
【点睛】
解决本题的关键是能够最大限度提高平底锅的利用率。
11．30
【分析】
找出尽可能可以同时做的事情，以此减少所用时间。
【详解】
洗衣服的同时可以扫地和擦洗家具。
8＋12＝21（分钟）21＜23；23＋7＝30（分钟）。
做完这些事情至少需要花30分钟。
【点睛】
找次品时，把待测物体分成3份，能够平分的就平均分成3份，不能平分的，应让多的或少的一份之差1，这样才能保证称的次数最少找出次品。
14．14
【分析】
考虑3个空瓶换一瓶汽水，为了最优，可以考虑“先借后还”，即先从商店拿部分汽水不付钱，然后空瓶换了汽水之后再还回去；据此思路解答即可。
【详解】
因为3个空瓶换一瓶汽水，先买14瓶汽水，向商店先拿一瓶汽水不付钱，喝完后正好是15个空瓶，可以换：
【点睛】
此题考查乘法和除法的实际应用。特别注意：亿后面是8个0和计算时一定要细心。
10．3
【分析】
要考虑最少的时间，就是充分利用平底锅每次只能烙两块饼进行分析，则可以首先取两张饼烙1分钟，再取出其中－张，将另一张的反面和新放入的第三张饼烙分钟，把烙好的第－张饼取出，最后剩下两张饼烙反面分钟，这样一共需要3分钟。
4＋6＋4＋1
＝10＋4＋1
＝14＋1
＝15（种）
故答案为：B
【点睛】
此题考查学生对排列、组合问题的运用。
4．B
【分析】
从特殊元素着手，C是特殊元素，C不能做中锋，先给C选个位置有4种选择，其余ABDE在剩余的四个位置任意项共有4×3×2×1＝24种，最后4×24＝96种。
【详解】

突然面对这么大的转变，我知道我必须得适应。
好在同事们都很乐意帮助我，这也给我了很大的动力去学习每件事情。
才来的那天最糗的事情就是去复印一点资料。
平时在学校复印东西都是打印店的人复印的，从来没有自己亲手复印过。
以为也没什么难的吧，谁知道我弄了半天都没复印出来，想想这么简单的事情又不好意思问同事，可急死我了。
好在一个同事姐姐看见了，主动教我怎么用，还跟我说以后再有什么不懂的就问她，不用觉得不好意思。
后来我就经常请教同事问题了，不会再觉得有什么好尴尬的了。
由于现在还住校，所以我每天7点不到就得起床去挤公交车，就算再寒冷再差的天气，只要不是周末，都得去上班，有时候公司业务繁忙，晚上或周末得加班，那留给个人支配的时间更少。
我必须克制自己，不能随心所欲地不想上班就不来，这也锻炼了我的自制能力。
常言道：工作一两年胜过十多年的读书。
实习时间虽然才几天，但是我从中学到了很多知识，关于做人，做事，做学问。
每日重复单调繁琐的工作，时间久了容易厌倦。
“在大学里学的不是知识，而是一种叫做自学的能力”。
参加工作后才能深刻体会这句话的含义。
我发现除了英语和计算机操作外，课本上学的理论知识用到的很少很少。
我担任的是文员一职，每天都是整理文档，负责人员考勤，薪资福利，接听电话等工作，虽然工作简单但也不能马虎，一个小小的错误可能会给公司带来巨大的麻烦或损失，还是得认真完成。
1个星期的实习时间看似不长，但是因为刚进公司，也许是最艰难的几天，需要适应的东西太多，我想我能够克服的，在克服的同时也尽量把工作做到最好。
周记二不觉中，来这里实习已十来天了，虽然时间已接近两星期，但是很多工作都还不是那么得心应手。
