（18分）阅读材料，回答问题。

材料一 中国首艘航空母舰“辽宁号”于2013年11月26日从军岛某军港起航开赴南中国海。航母这次远航的目的，一方面是通过长时间跨海区的航行，对有关设备的性能进行连续工作情况的检验，对部队整体训练水平进行考验和锻炼。另一更高层面的目的是编队协同、指挥试验与训练。辽宁舰自交付海军来，先后完成了航载战斗机阻拦着舰和滑跃起飞以及复杂气象连续起降条件下等试验与训练。而此次的编队远航训练则是中国航母发展史上的一个新的里程碑。此次演练选在南海海域是因为南海的气象、水文环境相对复杂，便于在训练中发现问题，及早形成预案，为未来中国航母到更远的海域执行任务积累经验。

材料二 西方军事学者认为，在现代战争中，被喻为“海上巨无霸”的航空母舰虽然仍将是海上作战兵器中首屈一指的“大哥大”，然而，产生于丘牛大车时代的《孙子兵法》揭示的战争普遍规律和基本的战略战术原则，在航母和核生化时代的战争中，仍然有很强的指导和借鉴作用。它是一种具有超越时代的思想体系。

（2）运用哲学相关知识分析在航母和核生化时代的战争中为什么仍然要重视《孙子兵法》。（6分）

                                                          Fix it on your own

     Did you know that a bowl of rice could save your iPod if you drop it in a swimming pool by accident?

Or that the camera on your phone could tell you what's wrong with your TV remote control? The experts

at Geek Squad (geelsquad.co.uk) have made a gadget (小机件) rescue guide. So, let's take a look at some

of their useful advice. 

     ● How to get more juice out of your phone battery (电池)

     If your battery goes dead but you need to get a number or send one last text, try warming it up. That

may give you a tiny bit of power. Take the battery from the phone and rub it between your hands. Or warm

it under your arm for a few minutes. Then try to start the phone-but use it quickly. 

     ● What to do if your gadget gets wet

     First, try drying it out with a vacuum cleaner. If a vacuum cleaner isn't at hand, fill a pot or bowl with

uncooked rice and put your wet gadget inside. The dry, uncooked rice will absorb all the water and, after

a few hours, you should be able to use the gadget: Don't forget to remove the battery and SIM card before

you dry it. 

     ● What to do if your TV remote control stops working

     If replacing the batteries doesn't work, get the camera function up on your phone and point the remote

at the lens (镜头). When you press a button on the remote, if it is working, the glass bobble (小球) at the

front of the remote will light up when you look at it on the screen of your phone. This is because the screen

on a phone or digital camera picks up infrared rays (红外线), even though your eyes don't. If the glass bobble

doesn't light up, the remote is broken. If it does, the receiving device is broken.
