In the light of the increasingly serious I/O bottleneck problem, the paper puts forward a method named RAID-M (RAID Matrix) to build high performance mass storage from cheap PC components based on the idea of multi-channel I/O and parallel access. Theoretical analyses prove that different RAID-M configurations vary their performance, space utilization and reliability, meeting various application goals. Experiments show that both the sequential read performance and sequential write performance of a RAID-M prototype machine have broken through the limitation of 32 bit/33 MHz PCI bus.

一老大爷坐火车，买的是慢车车票，却上了快车。乘务员查票时查到了，就对他说：“老人家，你的票要补哦！”可老大爷眼一瞪，说：“上面的洞洞是你们剪的，咋还喊我补哦？”乘务员傻眼了，又解释道：“不是票坏了喊你补，你买的票是慢车票，这趟车是快车，你应该补快车车票！”老人大悟，说：“哦！是这样啊，那你喊司机开慢点吧，反正我又不赶时间的。” 选自《中年读者》

材料点评是在新闻点评的基础上发展而来的一种新题型，纵观近几年的考查情况，“材料点评”类试题呈现以下几个特点。 1.紧扣时政热点。这是由“材料点评”中的“材料”的特点决定的，距离考生较远的材料，一般不会出现在试题中。 2.题型是主观题。材料点评一般是主观简答题，且比短评简短一些。 3.观点鲜明。点评要褒贬分明，观点正确，对症下药，切中要害，不能模棱两可。 预计2014年高考对“材料点评”类试
