【正文】 連接著韌帶以支持頭部的重量。四肢粗壯有力，前后腳均為3趾。白犀的皮膚并不是白色，而是藍(lán)灰色或棕灰色?！鞍紫钡拿Q來自于荷蘭語“weit”，意思為“wide”(寬平)，針對它們寬平的嘴唇而言，后來被人誤稱為“white” (白色)，故稱“白犀”?？兹笍念伾戏譃樗{(lán)孔雀、綠孔雀和白孔雀，其中藍(lán)孔雀數(shù)量非常多，是印度的國鳥，在國內(nèi)許多地方都有。白孔雀是孔雀的變種，數(shù)量不多。而綠孔雀僅分布于云南，數(shù)量十分稀少，藍(lán)孔雀羽毛主要為藍(lán)色，頭頂?shù)挠鸸诔噬刃斡鸸?，綠孔雀則身披墨綠色外衣，羽冠為集中的一簇。綠孔雀是同類中的“巨人”，體重達(dá)6公斤左右，所以在云南滬水俗稱“六公斤”?？兹搁_屏是雄孔雀向雌孔雀獻(xiàn)媚的一種手段。每年4至5月為孔雀的繁殖期，雄性全身羽毛煥然一新，張開美麗的翅膀和尾屏，不時戰(zhàn)栗著羽毛，追隨在雌鳥的周圍，翩翩起舞，發(fā)出“沙、沙”的聲音，以求得雌鳥的青睞。共有四個亞種。體羽無虹彩，主要為白色，頭頂有黃色冠羽，憤怒時頭冠呈扇狀豎立起來，就像一朵盛開的葵花。亞種中菲茨羅伊河亞種是藍(lán)眼圈，其他三種均是白眼圈。食物包括種子、殼類、漿果、堅果、水果、嫩芽、花朵、昆蟲等。語言能力一般。喙的力量強(qiáng)大，需要養(yǎng)在金屬籠子中。同許多鳳頭鸚鵡一樣，作為寵物飼養(yǎng)需要主人大量時間陪伴。羽粉較多，需要定期沐浴。叫聲嘈雜。野外分布于澳洲的北部、東部與南部，塔斯馬尼亞和印尼的一些島嶼。駱駝是內(nèi)蒙阿拉善雙峰駝毛色基因變異所形成的一個特殊類群。在風(fēng)調(diào)雨順、草原植被長勢良好的年景，雙峰直立、體格健壯、全身雪白的白駱駝，和藍(lán)天、白云、綠草交相輝映，或奔跑、或佇足站立，無不顯現(xiàn)出一種雍容華貴的氣質(zhì)，讓人美不勝收，極具觀賞價值。白駱駝生活力相對較弱，抗逆性能較差，所以在大旱之年死亡率要高于其它雙峰駝。阿拉善雙峰駝久負(fù)盛名，素有“駝鄉(xiāng)”之美譽(yù)。白駱駝數(shù)量在80年代初曾達(dá)7000余峰，以后由于連年干旱，尤其是連續(xù)幾年的大旱，白駱駝數(shù)量急劇下降，主要是自然死亡數(shù)量增多，至20xx年6月末，全盟白駱駝僅存千余峰，下降幅度高達(dá)8596以上，已瀕臨滅絕的危機(jī)。現(xiàn)在到阿拉善草原上己很難見到白駱駝的影跡。根據(jù)權(quán)威機(jī)構(gòu)和專家定論，動物數(shù)量在8000頭(只)以下視同為滅絕。因此保護(hù)白駱駝品種資源，使其優(yōu)良基因不致丟失，已是刻不容緩。黑尾牛羚。它的頭粗大而且肩寬很像水牛，后部纖細(xì)像馬，全身有長長的毛，光滑并有短的斑紋。顏色也因亞種、季節(jié)和性別的不同會有所不同。它們通常在清晨和午后活動，對環(huán)境的適應(yīng)能力很強(qiáng)。主要以草為食，也吃一些多汁的植物。壽命約15至20xx年。天鵝體長80至120厘米，體重6000至8000克。喜歡棲息于海灣、海岸、湖泊等水域。成對或結(jié)群生活，以水生植物或水生小動物為食。捕魚時采取彼此之間相互合作，將魚趕到淺灘后在捕捉，繁殖期為每年6至7月份，營巢筑在水邊隱藏處。它們是代表愛情忠貞的鳥兒，當(dāng)雌雄鳥彼此認(rèn)定對方之后，以后的日子就會形影不離。猩猩也叫人猿、紅猩猩、猩猩，靈長目人科的一屬，與猴子不同的地方就是沒有尾巴，能用手或腳拿東西。馬來語和印尼語叫做orang utan，意思是“森林中的人”。與人類十分相近，%?；顒拥牧?xí)性通常不用聲音溝通，通常有好幾個個體會在同一個區(qū)域活動，但彼此不干擾，平均壽命大概40年，平均身高大概171~180厘米左右。屬猩猩科，是一種非常珍稀的靈長類動物。人們把紅毛猩猩稱作世界上的憨態(tài)可掬的哺乳類動物。紅毛猩猩與大猩猩及黑猩猩一起常常被稱為“人類較為直系的親屬”沈陽森林野生動物園一日游篇九ladies and gentlemen:wele to the great wall. starting out in the east on the banks of the yale river in leaning province, the wall stretches westwards for 12,700 kilometers to jiayuguan in the gobi desert, thus known as the ten thousand li wall in china. the wall climbs up and down, twists and turns along the ridges of the yanshan and yinshan mountain chains through five provinces——liaoning, hebei, shanxi, shaanxi, and gansu and two autonomous regions——ningxia and inner mongolia, binding the northern china together.historical records trace the construction of the origin of the wall to defensive fortification back to the year 656 . during the reign of king cheng of the states of chu. its construction continued throughout the warring states period in the fifth century . walls, then, was built separately by these ducal states to ward off such harassments. later in 221 . the most extensive reinforcements and renovations were carried out in the ming dynasty (1368——1644) when altogether 18 lengthy stretches were reinforced with bricks and rocks. it is mostly the ming dynasty wall that visitors see today.the great wall is spanided into two sections, the east and west, with shanxi province as the spaniding line. the west part is a rammed earth construction, about meters high on average. in the eastern part, the core of the wall is rammed earth as well, but the outer shell is reinforced with bricks and rocks. the most imposing and best preserved sections of the great wall are at badaling and mutianyu, not far from beijing and both are open to visitors.the wall of those sections is meters high and meters wide at its base, narrowing to meters on the ramparts, wide enough for five horses to gallop abreast. twostoried watchtowers are built at approximately 400meters internals. the top stories of the watchtower were designed for observing enemy movements, while the first was used for storing grain, fodder, military equipment and gunpowder as well as for quartering garrison soldiers. the highest watchtower at badaling standing on a hilltop, is reached only after a steep climb, like climbing a ladder to heaven.there stand 14 major passes (guan, in chinese) at places of strategic importance along the great wall, the most important being shanghaiguan and jiayuguan. yet the most impressive one is juyongguan, about 50 kilometers northwest of beijing.known as tian xia di yi guan (the first paunder heaven), shanghaiguan pais situated between two sheer cliffs forming a neck connecting north china with the northeast. it had been, therefore, a key junction contested by all strategists and many famous battles were fought here. it was the gate of shanghaiguan that the ming general wu sangui opened to the manchu army to supprethe peasant rebellion led by li zicheng and so surrendered the whole ming empire to the manchus, leading to the foundation of the qing dynasty. (16441911)as a cultural heritage, the wall belongs not only to china but to the world. the venice charter says: historical and cultural architecture not only includes the inspanidual architectural works, but also the urban or rural environment that witnessed certain civilizations, significant social developments or historical events. the great wall is the largest of such historical and cultural architecture, and that is why it continues to be so attractive to people all over the world. in 1987, the wall was listed by unesco as a world cultural heritage site.
