還有一個是講鳥 什么hummingbirds蜂鳥。在GERMANY的西南發(fā)現(xiàn)了 以前一直以為只有在非洲和南美有。
二、考古【感謝 元蜀黍】
【版本一】
P1.從化石里發(fā)現(xiàn)很久以前old world(非洲歐洲)有蜂鳥,但現(xiàn)在滅絕了。
P2.出現(xiàn)了2個new finding 不停的question 或者是evaluate 蜂鳥化石。
Q1.主題題
Q2.下面哪個能夠strength old world有蜂鳥。
【版本二】710 V37
有一段說有古蜂鳥吃一種植物,后來被現(xiàn)代的昆蟲傳播,所以現(xiàn)代的蜂鳥也可以食用(大概是這個意思吧,有考題)
最后一段說到一個尚未解決的問題,就是為什么蜂鳥沒有居住在更廣闊的地方,而他們的食物鏈明顯可以擴展到比現(xiàn)在更廣闊的領(lǐng)域。(有考題)
Q1.怎么證明蜂鳥化石與現(xiàn)代蜂鳥是同宗。我選的與一種植物有關(guān)(好像是哦)
Q2.為什么沒有擴展到比現(xiàn)在更廣闊的地方
【版本三】
P1.科學(xué)家發(fā)現(xiàn)了蜂鳥化石,闡述了這種蜂鳥與現(xiàn)代蜂鳥的相似性,以及相關(guān)特征。
P2.發(fā)現(xiàn)很久以前有一種花兒,開始時由蜂鳥來傳媒接種的,但是后來發(fā)現(xiàn)又另外一種昆蟲,代替了蜂鳥化石,傳媒接種。
整篇文章討論了蜂鳥化石的發(fā)現(xiàn)以及一些有關(guān)的推斷。
Q1.主旨題。
三、背景資料
The birds were discovered near the village of Frauenweiler in southern Germany. Germany and all of Europe is part of the "Old World" – a region that also includes Africa, Asia and Australia. Finding modern-looking hummingbird fossils in the Old World might help to explain the existence of certain flowers in Asia and Africa that seem to scream, "I'm trying to attract a hummingbird!" Why do plants with flowers that seem to be designed to feed a hummingbird grow in parts of the world with no hummingbirds? Mayr has one possible explanation. He imagines a time when the ancestors of these hummingbird-friendly flowers and hummingbirds lived together in the Old World. They may have each changed the appearance of the other through a process of back-and-forth interaction called "coevolution." At some point the hummingbirds disappeared but the plants lived on, according to Mayr. Insects like long-tongued bees could have taken over the hummingbirds' pollination duties. Pollination is necessary for plants to produce seeds. This "case of the disappearing hummingbird" is a good example of how discovery of a very old fossil can change the way we look at the plants and animals that are alive today. Mayr named the new hummingbird species Eurotrochilus inexpectatus, which means an "unexpected European version of Trochilus." Trochilus is the name of a group of today's hummingbirds.
