解题思路：购买这些钢笔需要花60元；经过协商，每种钢笔单价下降1元，结果只花了48元，可知钢笔有12支，可设甲种钢笔有x支、乙种钢笔有y支、丙三种钢笔有z支，可列方程，得到整数解即可．

设甲种钢笔有x支、乙种钢笔有y支、丙种钢笔有z支，则


x+y+z＝60−48
4x+5y+6z＝60，
其中x=11，x=9，x=7时都不符合题意；
x=4时，y=4，z=4符合题意．
故选：D．

有只蚊子飞到狮子那里,说：“我不怕你,你也并不比我强多少.你的力量究竟有多大?是用爪子抓,还是用牙齿咬?仅这几招,女人同男人打架时也会用.可我却比你要厉害得多.你若愿意,我们不妨来比试比试.”蚊子吹着喇叭,猛冲上前去,专咬狮子鼻子周围没有毛的地方.狮子气得用爪子把自己的脸都抓破了,最后终于要求停战.蚊子战胜了狮子,吹着喇叭,唱着凯歌,在空中飞来飞去,不料却被蜘蛛网粘住了.蚊子将被吃掉的时候,悲叹道：“我已战胜了最强大的动物,却被这小小的蜘蛛所消灭.”
蚊子被蜘蛛吃掉了,蜘蛛很满足,于是就躺在网上晒起了太阳,自满地说：“最强大的狮子被蚊子打败了,我又打败了蚊子,看来还是我最强大!”
这件事就这样在森林里传开了,现在所有的动物都认为狮子已不是最强大的,都认为蜘蛛是森林之王.
狮子在森林里便再也直不起腰了,没有谁再怕狮子,就连一只小蚂蚁见了狮子也昂首挺胸,没有一丁点儿的畏惧.
但是狮子毕竟是森林之王,它没有就此消沉下去,而是整日加紧训练,变得更加强壮,因为它要夺回“森林之王”的称号!
一个月后,狮子已完成了自己的训练计划,便向蜘蛛下了战书,两天后在空地决战.
两天后,狮子充满信心地来到了空地,但左等又等也不见蜘蛛,只好向蜘蛛“老巢”进军.
蜘蛛呢?原来在收到战书时,的确担心了一阵,但想到自己是森林之王,就仍旧睡大觉,晒太阳,今天,都忘了这事.
狮子来到了蜘蛛的领地,吼了几声,蜘蛛惊醒,想逃,但是这些日子把身体养得太胖,所以还没跑几步,便被跳上来的狮子踩成了肉饼.

解题思路：由于“海拔每上升100米，气温就下降0.6℃”，因此，应先求得峰顶与珠峰大本营的高度差，进而求得两地的温度差，最后依据珠峰大本营的温度计算出峰顶的温度．

由题意知：峰顶的温度=-4-（8844.43-5200）÷100×0.6≈-25.87≈-26℃．
故选A．

...but I don't think I'm quite ready with that.
The fact is that I'm afraid of speaking English during lessons. That's probably because I'm afraid of making stupid mistakes and get laughed at by everyone. And during role plays and parties related to speaking English, again I'm worried about my English level. When I meet foreigners, my fear is at its most. How hard it is to speak a word in English, when I'm so concerned about some mistakes being made fun of by them!
I would say, the crucial point of this whole English phobia is that I'm afraid of making mistakes.
I will appreciate that if I can be pointed to some sort of a direction by you people.
