Recently a Beijing father sent in a question at an Internet forum (论坛) asking what "PK" meant.

"My family has been watching the 'Super Girl' singing competition TV programme. My little daughter asked me what 'PK' meant, but I had no idea," explained the puzzled father.

To a lot of Chinese young people who have been playing games online, it is impossible not to know this term. In such Internet games, "PK" is short for "Player Kill", in which two players fight until one ends the life of the other.

In the case of the "Super Girl" singing competition, "PK" was used to refer to the stage where two singers have to compete with each other for only one chance to go up in competition ranking.

Like this father, Chinese teachers at high schools have also been finding their students' compositions using Internet jargons which are difficult to understand. A high school teacher from Tianjin asked her students to write compositions with simple language, but they came up with a lot of Internet jargons that she didn't understand.

"My 'GG' came back this summer from college. He told me I've grown up to be a 'PLMM'. I loved to 'FB' with him together; he always took me to the 'KPM'," went one composition.

"GG" means Ge Ge (Chinese pinyin for brother). "PLMM" refers to Piao Liang Mei Mei (beautiful girl). "FB" means Fu Bai (corruption). "KPM" is short for KFC, Pizza Hut and McDonald's.

Some specialists welcome Internet jargons as a new development in language.

If you do not even know what a Kong Long (dinosaur, referring to an ugly looking female) or a Qing Wa (frog, referring to an ugly looking male) is, you will possibly be regarded as a Cai Niao!

A.explain some Internet language

D.draw our attention to Internet language小题2:What does the writer think about the term "PK"?

A.are used not only online

B.can be understood very well

阅读材料,回答问题。(16分)

材料一  1937年7月22日,国民政府资源委员会提出了东部工业西迁的构想。……8月11日,上海工厂迁移监督委员会成立。……9月下旬,新成立的军事委员会工厂调整委员会取代上海迁移监督委员会,全面负责沿海工矿业的内迁工作。27日,工矿调整委员会讨论确定了通过工厂迁移原则,将迁移工厂分为军需工厂和普通工厂两类,规定:“军需工厂系指国防上必需该厂之助,由政府令其迁移,……此等工厂之迁移得由政府按其个别情形酌予补助”, “普通工厂为指定军需工厂以外之工厂。凡愿迁移,呈经政府核准者,得予以免税、免验、减免运费、便利运输或征收地亩等之援助。惟因财政所限,不补助迁移费。”

由于战局发展,工矿内迁工作到1940年底基本完成。据行政院报告,经国民政府协助而内迁的厂矿共达448家,技术人员有12080人,机器材料70900吨。其中属于国防工业范围的厂家达60%以上。

——张海鹏《中国近代通史》

材料二  1937年后方只有工厂63家,1938年增至219家,1940年为571家,1941年达到1138家。……后方工业中属于重工业的工厂占工厂总数35%左右,以资本计约占50%左右,改变了战前轻工业优势的状况。在工业布局上,重庆是最大的工业中心,加之四川其他地区,占厂数的45%以上、资金的53%。其余工业分布于湘、桂、陕、甘、黔、滇等省的主要城市。这样就使战前工业布局严重不合理的状况有所改变。

——王桧林《中国现代史》

请回答:

(1)据上述材料并结合所学知识,指出工矿调整委员会通过工厂迁移原则的历史背景。(4分)
