⑴ 點讀筆哪個牌子的好,啟智星的怎麼

買點讀筆要看兩方面,一是筆的質量,包括硬體構造和音質等,通過看和聽就能判斷出來;二是書,沒有書,點讀筆就是塊廢塑料,所以選書也是家長要考慮的內容。啟智星的還不錯,音質,書都還可以。

⑵ 2006年袋鼠金幣澳大利亞為什麼把袋鼠作為金幣徽章

象徵性就和央行發行的熊貓金幣一樣

⑶ 普通袋鼠和紅袋鼠的區別。。。急急急!!!今晚就要。。

袋鼠(kangaroo)原產於澳大利亞大陸和巴布亞紐幾內亞的部分地區。其中,有些種類為澳大利亞獨有。所有澳大利亞袋鼠,動物園和野生動物園里的除外,都在野地里生活。不同種類的袋鼠在澳大利亞各種不同的自然環境中生活,從涼性氣候的雨林和沙漠平原到熱帶地區。
袋鼠是食草動物,吃多種植物,有的還吃真菌類。它們大多在夜間活動,但也有些在清晨或傍晚活動。不同種類的袋鼠在各種不同的自然環境中生活。比如,波多羅伊德袋鼠會給自己做巢而樹袋鼠則生活在樹叢中。大種袋鼠喜歡以樹、洞穴和岩石裂縫作為遮蔽物。
所有袋鼠,不管體積多大,有一個共同點:長著長腳的後腿強鍵而有力。袋鼠以跳代跑,最高可跳到4米,最遠可跳至13米,可以說是跳得最高最遠的哺乳動物。大多數袋鼠在地面生活,從它們強健的後腿跳越的方式很容易便能將其與其他動物區分開來。袋鼠在跳躍過程中用尾巴進行平衡,當它們緩慢走動時,尾巴則可作為第五條腿。
所有雌性袋鼠都長有前開的育兒袋,育兒袋裡有四個乳頭。「幼崽」或小袋鼠就在育兒袋裡被撫養長大,直到它們能在外部世界生存。
袋鼠屬有袋鼠為袋鼠科,結指鼠兒亞目,袋鼠目,有帶類,哺乳動物綱,脊索動物門,動物界,它們是澳大利亞著名的哺乳動物,在澳洲佔有很重要的生態地位。袋鼠前肢短小,後肢特別發達,常常以前肢舉起,後肢坐地,以跳代跑。袋鼠一般身高有2.6米,體重約有80公斤。
袋鼠圖常作為澳大利亞國家的標識,如綠色三角形袋鼠用來代表澳大利亞製造。袋鼠圖還經常出現在澳大利亞公路上,那是表示附近常有袋鼠出現,特別是夜間行車要注意,袋鼠的視力很差,加上對燈光的好奇會跳去「看個究竟」。但因為袋鼠的繁殖率高所以即使不小心撞死了也不需要負責,會有專門的人把袋鼠的屍體收走。
袋鼠通常以群居為主,有時可多達上百隻。但也有些較小品質的袋鼠如wallabies會單獨生活。
袋鼠不會行走,只會跳躍,或在前腳和後腿的幫助下奔跳前行。袋鼠屬夜間生活的動物,通常在太陽下山後幾個小時才出來尋食,而在太陽出來後不久就回巢。
袋鼠每年生殖一至二次,小袋鼠在受精 30-40 天左右既出生,非常微小,無視力,少毛,生下後立即存放在袋鼠媽媽的保育袋內。直到 6-7 個月才開始短時間地離開保育袋學習生活。一年後才能正式斷奶,離開保育袋,但仍活動在媽媽袋鼠附近,隨時獲取幫助和保護。袋鼠媽媽可同時擁有一在袋外的小袋鼠,一在袋內的小袋鼠和一待產的小袋鼠.

紅袋鼠
最著名的袋鼠是紅袋鼠,其體型最大,生活在澳大利亞乾燥地帶,其地帶的年平均降雨量在 500毫米以下。由於袋鼠的食物含大量水分,所以他在沒有活水的地區也能生存。紅袋鼠實際上只有公袋鼠是紅色的,母袋鼠為灰藍色。
紅袋鼠又名大赤袋鼠。這類袋鼠是袋鼠科中體型最大的一種,產於澳大利亞及其附近島嶼,是澳大利亞的特產動物之一。紅袋鼠其實只有雄性體色是紅色或紅棕色,其雌性體色都呈藍灰色。袋鼠前肢短小,後腳長而有力,行進時,完全以後腳來跳,大尾巴則保持平衡。它們善於跳躍,能跳7—8米遠,1.5—1.8米高。如果它們去參加奧運會,一定能拿到「雙跳冠軍」。大袋鼠喜歡搞「小團體」,往往是結小群生活於草原地帶,活蹦亂跳地在夜間覓食各種草類、野菜等。它們一般1.5—2歲成熟,壽命20—22年,被列入瀕危野生動植物國際公約附錄上。紅袋鼠全年均可繁殖,經過艱苦的「十月懷胎」—袋鼠的孕期為343天,一般產下一仔。當袋鼠媽媽快生小寶寶時,便忙著口袋,用舌頭把裡面的臟東西舔干凈。
袋鼠家族中「種族歧視」十分嚴重,它們對外族成員進入家族不能容忍,甚至本家族成員在長期外出後再回來也是不受歡迎的。家族即使接受新成員,也要教訓一番,直到新成員學會許多「規矩」後,才能和家族融為一體。
生活於澳大利亞東南部開闊的草原地帶的大赤袋鼠是最大的有袋動物,也是袋鼠類的代表種類,堪稱現代有袋類動物之王。
大赤袋鼠的形體似老鼠,彷彿一隻特大的巨鼠。其實,它與老鼠並沒有什麼親緣關系。它的體毛呈赤褐色,體長130—150厘米,尾長120—130厘米,體重70—90千克。頭小,顏面部較長,鼻孔兩側有黑色須痕。眼大。耳長。相貌奇特,惹人喜愛。它們的頭小,耳大,眼睛也很大。適應於跳躍的生活方式,前肢短小而瘦弱,可以用來摟取食物,後肢強大,趾有合並現象,一步可跳5米遠,時速可達40—65公里。尾長大,為棲息時的支撐器官和跳躍時的平衡器。
大赤袋鼠多在早晨和黃昏活動,白天隱藏在草窩中或淺洞中。喜歡集成20~30隻或50~60隻群體活動,以草類等植物性食物為主。它膽小而機警,視覺、聽覺、嗅覺都很靈敏。稍有聲響,它那對長長的大耳朵就能聽到,於是便溜之大吉了。

⑷ 澳大利亞黃袋鼠和紅袋鼠紅酒的區別

都是同一個瓶塞同一個系列下面不同的釀酒品種區別,黃色是設拉子葡萄釀制,紅袋鼠是赤霞珠葡萄,還有個橙色是梅洛葡萄。前兩者口感比較濃郁,後者比較清淡些。

⑸ 澳洲政府徽章,一個是袋鼠,另一個動物是什麼

鴯鶓
鴯鶓(學名:Dromaius novaehollandia)是鳥綱鴯鶓科唯一的物種,以擅長奔跑而著名,是澳洲地區的特產,是世界上第二大的鳥類,體型僅次於非洲鴕鳥,因此也被稱作澳洲鴕鳥,也被稱作尤加利鳥,翅膀比非洲鴕鳥和美洲鴕鳥的更加退化,足三趾,是世界上最古老的鳥種之一。盛通海外竭誠為您服務

⑺ 關於考拉和紅袋鼠的英語資料

考拉:
What is a koala?

The koala is a small bear-like, tree-dwelling, herbivorous marsupial which averages about 9kg (20lb) in weight. Its fur is thick and usually ash grey with a tinge of brown in places.
The koala gets its name from an ancient Aboriginal word meaning "no drink" because it receives over 90% of its hydration from the Eucalyptus leaves (also known as gum leaves) it eats, and only drinks when ill or times when there is not enough moisture in the leaves. ie ring droughts etc.
The koala is the only mammal, other than the Greater Glider and Ringtail Possum, which can survive on a diet of eucalyptus leaves.

Habitat & Diet

'Habitat' refers to the types of bushland that koalas like to live in. They are found in a range of habitats, from coastal islands and tall eucalypt forests to low woodlands inland.
Koalas today are found in Queensland , New South Wales , Victoria and South Australia . Their range extends from the Atherton Tableland west of Cairns in Qld to islands off the coast of Victoria and South Australia in the south, and west to central and western Qld, NSW and Victoria.
Koalas live in societies, just like humans, so they need to be able to come into contact with other koalas. It is because of this they need to have areas of suitable eucalypt forest which are large enough to support a healthy koala population and to allow for expansion by maturing young koalas. Koalas are highly territorial and in stable breeding groups, indivial members of koala society maintain their own "home range" areas.
A 戚ome range� consists of a number of 戚ome range trees� and 慺ood trees� which comprise the long-term territory of the indivial koala. These trees provide the koala with food, shelter and places for social contact which will support it for the term of its natural life (assuming there is no habitat clearing).
A home range varies in size depending on the habitat quality of bushland. Habitat quality can be measured in terms of the density of key food trees. "Home range trees" define the boundaries of the indivial koala抯 home range and can be likened to surveyors pegs marking the extent of a property. They are not always apparent to the human eye, but koalas can tell whether a tree 慴elongs� to another koala or not. Within a socially stable group, the home ranges of indivial koalas overlap with those of their neighbours. It is in the shared, overlapping trees that the majority of social interaction takes place. These are very important trees.
Koala populations only occur if suitable habitat is available and because Koala's are very fussy eaters and have strong preferences for different types of gumleaves, then the most important factor which make habitats suitable are the presence of tree species preferred by koalas (usually eucalypts, but also some non-eucalypts) growing in particular associations on suitable soils with adequate rainfall.
Research has shown that socially stable koala populations occur only when there are favourite tree species present. Even if a selection of tree species known to be used by koalas occurs within an area, the koala population will not use it unless one or two favourite species are available.
In Australia there are over 600 types of eucalypts, but koalas will only eat 40-50 varieties with only about 10 being preferred. Within a particular area, as few as one, and generally no more than two or three species of eucalypt will be regularly browsed while a variety of other species, including some non-eucalypts, appear to be browsed occasionally or used for just sitting or sleeping in.
Different species of eucalypts grow in different parts of Australia, so a koala in Victoria would have a very different diet from one in Queensland. Koalas like a change, too, and sometimes they will eat from other trees such as wattle or tea tree.
Eucalyptus leaves are very fibrous and low in nutrition, and to most animals are extremely poisonous. To cope with such a diet, nature has equipped koalas with specialised adaptations. A very slow metabolic rate allows koalas to retain food within their digestive system for a relatively long period of time, maximising the amount of energy able to be extracted. At the same time, this slow metabolic rate minimises energy requirements and they will sleep for up to 18 hours per day in order to conserve energy.
Each koala eats approximately 200 to 500 grams of leaves per day. The teeth are adapted to deal with for this. The sharp front incisors nip the leaves from the branches and the molars(back teeth) are shaped to allow the koala to cut and shear the leaves rather than just crush them. A gap between the incisors and the molars, called a 'diastema', allows the tongue to move the mass of leaves around the mouth efficiently.

紅袋鼠
The red kangaroo is the world's largest marsupial. Females have one baby at a time, which at birth is smaller than a cherry. The infant immediately climbs into its mother's pouch and does not emerge for two months. Until they reach about eight months of age, threatened young kangaroos, called joeys, will quickly dive for the safety of mom's pouch. As they grow, joeys' heads and feet can often be seen hanging out of the pouch.
Red kangaroos hop along on their powerful hind legs and do so at great speed. A red kangaroo can reach speeds of over 35 miles (56 kilometers) an hour. Their bounding gait allows them to cover 25 feet (8 meters) in a single leap and to jump 6 feet (1.8 meters) high.
Female red kangaroos are smaller, lighter, and faster than males. They also boast a blue-hued coat, so many Australians call them "blue fliers."
Larger male kangaroos are powerfully built. Like many species, male kangaroos sometimes fight over potential mates. They often lean back on their sturdy tail and "box" each other with their strong hind legs. Kangaroos can also bite and wield sharp claws, which they may do in battle with an enemy like a dingo.
Red kangaroos live in Australia's deserts and open grasslands, gathering in groups called mobs. Aboriginal and European Australians have spent centuries clearing open tracts of land and establishing water sources—both of which are boons to kangaroo populations. Many millions of these animals roam Australia, and considerable numbers are killed each year for their skins and meat, which is becoming a more popular human food.

⑼ 袋鼠的種類分幾種分別是

分5種,分別為紅袋鼠、大赤袋鼠、東部灰大袋鼠、西部灰大袋鼠、麝香袋鼠

1、紅袋鼠

紅袋鼠,廣泛分布在澳洲大陸,棲息在澳洲中部的乾旱內陸,以及較少樹生長的遼闊平原。

2、大赤袋鼠

生活於澳大利亞東南部開闊的草原地帶的大赤袋鼠是最大的有袋動物,也是袋鼠類的代表種類,堪稱現代有袋類動物之王。

3、東部灰大袋鼠

是澳大利亞南部及東部的袋鼠,東部灰大袋鼠可以移動得很快,最高紀錄達每小時64公里。

4、西部灰袋鼠

西部灰袋鼠,生活在開闊的林地、荒原和草場,黃昏至清晨活動覓食,以草、樹葉、樹皮和灌木為食,對於某些植物毒素它具有較高的耐受性。

5、麝袋鼠

麝袋鼠,是哺乳綱下雙門齒目下的單科種,僅在近年才將其置放在目前的一個科內,麝袋鼠科,並與遠古時代的其他麝袋鼠共用此科。

⑽ 和紅袋鼠體型相似的動物

是袋鼠科、大袋鼠屬動物。紅袋鼠是世界上最大的有袋類動物。紅袋鼠體長100-160厘米,尾長75-120厘米,體重23-70千克。雄性體長130-160厘米,體重70-90千克,雌性則小得多。紅袋鼠體色呈紅色或紅棕色,因而得名。但雌性體色呈藍灰色,鼻孔兩側有黑色須痕,這是紅袋鼠獨具的特徵。
紅袋鼠棲息在熱帶的稀樹草原、荒漠和溫帶的森林中。非常善於跳躍,在緩慢行進時,每一跳約1.2-1.9米,但在奔跑時每一眺可達9米以上。短期的逃跑速度可達每小時50-64千米。生性膽小,機警,常於夜間或清晨活動,日間多睡覺或以其他方式休息。廣泛分布於澳大利亞(除了北部、東海岸和西海岸)。
紅袋鼠棲息在熱帶的稀樹草原、荒漠和溫帶的森林中。紅袋鼠和羚袋鼠一樣,喜歡群棲,常以2-10隻為一個社群單元,有時也結成上百隻的大群;在草原地帶集成小群一起生活。非常善於跳躍,在緩慢行進時,每一跳約1.2-1.9米,但在奔跑時每一眺可達9米以上。短期的逃跑速度可達每小時50-64千米。生性膽小,機警,常於夜間或清晨活動,日間多睡覺或以其他方式休息。一般在清晨和傍晚天氣涼爽時外出覓食飲水,白天炎熱時成群在樹陰下休息。休息、時總有一隻袋鼠放哨,一發現稍有危險徵兆,立即發出警報。受驚時會發出大聲的咳嗽聲,並用後足猛擊地發出聲來,而後會一下子跑出幾公里才停下。主要在夜間覓食,食物為各種草類、野菜、樹葉等。[5][7][8][6][9]
紅袋鼠平時比較安靜,也比較溫順,但在無退路時也會用後足猛踢人,它的後足強有力,一下子就可以使人致命。雄性在爭勝打架時動作如同人在拳擊。[9]紅袋鼠的尾部在其跳躍時起平衡作用;當遇到敵害走投無路時,尾巴的抽擊能造成致命傷;在慢行和休息時尾巴又可作為第三肢,與後胺形成天然的椅子。
