阅读《瘦西湖公园》，完成小题。
        ①瘦西湖公园位于古城扬州的西北部，总面积103.7公顷，其中水面面积 49.9公顷。瘦西湖原名炮山河，一名保障河。清乾隆时，因其绕长春岭（即小金山），又称长春湖。六朝以来，即为风景胜地。
        ②瘦西湖园林群景色怡人，融南秀北雄为一体，在清代康乾时期即已形成基本格局，有“园林之盛，甲于天下”之誉。其名园胜迹，散布在窈窕曲折的一湖碧水两岸，俨然一幅次第展开的国画长卷。
        ③隋唐时期，瘦西湖沿岸陆续建园。及至清代，由于康熙、乾隆两代帝王六度“南巡”，形成了“两堤花柳全依水，一路楼台直到山”的盛况。瘦西湖风景区是蜀冈---瘦西湖国家重点风景名胜区的核心和精华部分。
        ④“天下西湖，三十有六”，惟扬州的西湖，以其清秀婉丽的风姿独异诸湖。一泓曲水宛如锦带，如飘如拂，时放时收，较之杭州西湖，另有一种清瘦的神韵。清代钱塘诗人汪沆有诗云：“垂杨不断接残芜，雁齿虹桥俨画图。也是销金一锅子，故应唤作瘦西湖。”瘦西湖由此得名，并蜚声中外。一个"瘦"字，可谓是点睛之笔。诗人的妙喻，绝妙地表现了扬州瘦西湖纤秀、苗条、俊俏的风韵，从而同杭州西湖雍容、圆润、丰腴的丰姿有别。
        ⑤瘦西湖清瘦狭长，水面长约4公里，宽不及100米。原是纵横交错的河流，历次经营沟通，运用我国造园艺术的特点，因地制宜地建造了很多风景建筑。瘦西湖从乾隆御码头开始，沿湖过冶春、绿杨村、红园、西园曲水，经大虹桥、长堤春柳，至徐园、小金山、钓鱼台、莲性寺、白塔、凫庄、五亭桥等，再向北至蜀岗平山堂、观音山止。湖长十余里，犹如一幅山水画卷，既有天然景色，又有扬州独特风格的园林。
        ⑥瘦西湖园林以自然风光旖旎多姿著称于世。四时八节，风晨月夕，使瘦西湖幻化出无穷的天然之趣。丰富的历史文化，使瘦西湖如醇厚的佳酿，常看常新，品味其中，回味无穷。瘦西湖为我国著名的湖上园林，窈窕曲折的湖道，串以长堤春柳、荷蒲薰风、四桥烟雨、徐园、小金山、吹台、水云胜概、五亭桥、白塔晴云、二十四桥景区，虹桥等景点，俨然一幅天然而成的国画长卷。虹桥建于明末，是座红栏木桥，现为石砌拱桥。这儿满湖的荷花与夹岸的垂杨，映着两岸的曲栏雕柱。正如清王士桢诗所云：“红桥飞跨水当中，一字栏杆九曲红。日午画船桥下过，花看人影太匆匆。”
        ⑦瘦西湖的景点经多年修建，变得格外妩媚多姿。荡舟湖上，沿岸美景纷至沓来，让人应接不暇，心迷神驰。

     A serious earthquake can be a terrible experience, and it is easy to forget safety measures(措施) in disorder(混乱). Fortunately, most earthquake safety measures are common sense, but if you forget everything else, re­member the following instructions: drop, cover, and hold on. Also, most of earthquake deaths hap­pen after the earthquake, so remember that the danger does not end when the shaking does!

     If you stay indoors during an earthquake, move away from unsupported areas and windows. Try to get under a doorway or another area of the building which is held up by strong beams(梁).  Stay under a table or desk only if it is very strong. Do not rush to lifts, because it is far safer to stay where you are. Cover your head with your arms around it and curl (蜷缩) into a ball, and wait for the shaking to stop.

     If you stay outdoors during an earthquake, move to an area which is as open as possible. Don't move to build­ings, electric poles and other objects which may fall during an earthquake and injure you. Protect your head and stay low to the ground till the shaking ends and it is safe to move.

     After an earthquake, many buildings are less strong, although they appear safe. If you stay indoors, move people from the building quickly and help disabled or injured people. Once outdoors, move well away from the building so that if it falls down, you will not be injured. Wait till public safety officials an­nounce that it is safe to stay indoors.

     By planning ahead and keeping calm during an earthquake, you can greatly increase your chances of survival(生存) without injury.
