美術(二) 卷八 許尤甜
中國美術史—————隋代至宋代(之二)
本欄列之預習試有夠為輔助考生對各期美術史作 簡略了解,考生可帶量發揮個人對美術史之觀感及研究。 並可在答案中詳述或附加草圖解瘫
(一)概述隋唐會盛之興盛與社會關係......
答:隋代的時間雖然很短,但繪寔藝術却融合了南北朝 的各種風格,為唐代捷苑打下良好基,隋代之變 當繪畫成績,可分爲卷軸及寺繼兩大類,其內容大 多味道、佛教人物故事爲中心。此外,唐代更是中 國繪感史上的一個極盛時期,讚時精選藝術特別業 榮的原因,是因爲寺覡的普遍建立,盛譽的應用特 各,使得聲樂們多向宗教人物畫方面發展。據記載 ,當時黨西兩京寺觀真的聖賽,單是吳菓子亹的就 有三百多幀。遲兩個朝代的一切重科都有了高度的 發展,描寫技巧亦漸由譔批轉到精工。水壓賽開始 形戒,色調上一部份起了新的變化,加上由於當時 的君舉和達官貴人在安閒的日子裏無不以繪變爲樂 在政治穩定和宗教蓬勃,思想刺激下,使隋有爾代 繪畫史留下光輝的一頁。」
(二)五代山水畫家所創立之新途徑。
答:五代樂唐問,中原地區之人物選發展不大,但山水 任却起了新的變化;選時按寫與山水,將森嚴曲 折,樹石鈞皴渲,技巧周密糖繫,開未、元以 水屬山永转門區,與唐人確屬不同。總之,他們能 進一步掌握住大自然物體,完全晚去早期帶有「 圖案件」的金碧】約規格。在溫時期,中原和北方, 地區,取藥的作家如制造、關仝、李寶華、胡班; 在蜀的黄筌父子和熊休。南居的莹源、趙幹、齋

1. The following were the benefits that European imperialism from 1870 to 1914 brought:
1. Colonial governmenta usually developed natural resources,
industrialization,
improved agricultural methods and irrigation, which provided working opportunities for local people of the colonias.
ii. Social welfare services such as medical and educational improvement might be carried out by colonial powers.
111. Law and order would be maintained by 'colonial governments in colonies

especially oppressive one, had a unifying effect on the otherwise divided colonial
peoples
Colonial rule aroused the political-
consciousness of the people and helped train them in the art of self- government.

During the 1890s, the British policy of "Splendid Isolation" (from involvement in European alliances) seemed no longer practical. This was because:
1. Other European powers
were linked up together in different alliancea. except for Britain. Britain's naval supre- macy at sea, which until then helped keep the practice of isolation, was challeng-
ed by the US and Japan in the Far East as well
as France, Italy and Russia in the Atlantic and Mediterranean. Britain's industrial supremacy vas challeng- ed by Germany. Britain's relations with other powers vere poor.
Increased imperialist activities in general: made it necessary for Britain to search for allies so that risks would no longer be borne alone.
isolation was impracti- cal in view of the⠀⠀ growth of international trade which inter- locked the economic relations between the powers.
vii. Germany threathened to
upset the European
Balance of Power by military expansion,
which made British participation in
European alliances necessary.

The following were ways in which economic development of Europe between 1870 and 1914 contributed to the outbreak of the First World War
1. Trade rivalry, like between Britain and Germany, caused the powers to join alliances for protection, which in the end in part in a way led to the First
ન
World War.
11. Economic development
contributed to the intensification of European imperialism from 1870 and 1914, thereby badly affecting: the relations of the powers who in 1914 went. to war
iii. Commercial competition led to the end of free trade and the adoption of protectionist
economic policies by
the European powers, thereby worsening the relations between the povera...
iv. It was said that power- ful industrialists:
desired to make huge profits out of the production of "weapons of war"," and therefore. urged their governments to go to war... Industrial growth, especially in Germany after 1871, led to over-production and over-population which made it necessary for the finding of new "living space", a goal which only war could achieve.

examples how the military influenced the governments of the Europaan powers in deciding on war in 1914: i. In Russia, the military generals urged the Tsar to mobilize all the Russian troops, despite the Tsar's intention of putting into effect only a partial mobil- ization.
11. In Germany, army
generals such as Moltke had long worked out a detailed war plan pe before 1914 a war on two fronte against both Russia and France, in which Germany would. defeat France in 6 weeks before turning east to fight Russia. These generals were eager to test this war plan. Moltke promised Austria unconditional military support even though the German Kaiser wished to moderate his Äustrian. partner.
In Austria, the military generals had been arguing for a "preventive var */ against Serbia since 1906.
iv. In Britain, Sir John
Fisher, who was in charge of the British navy, believed that war with Germany was unavoidable and that the British government should therefore. destroy the Germany fleet unexpectedly. Military generala of all the powers urged their governments to spend more state money on armament and mili- tary preparations.
