素養(yǎng)解讀: 我們生活的地球有三分之二的面積被水覆蓋。因此很久以前,人類就開始認(rèn)識海洋、探索海洋。為了尋找海洋航線,我們的祖先不畏艱辛,克服種種困難,為人類征服海洋做出了巨大的貢獻(xiàn)。歷史上,鄭和七下西洋,遠(yuǎn)及非洲沿岸各國。了解這些歷史,有助于培養(yǎng)同學(xué)們的文化意識,了解古代中國的強(qiáng)盛,增強(qiáng)同學(xué)們的民族自豪感,提升我們的民族自信心。此外,閱讀有關(guān)海洋探索類的文章,還有助于同學(xué)們認(rèn)識海洋,并且培養(yǎng)同學(xué)們自覺熱愛海洋、保護(hù)海洋、熱愛祖國的思想意識。
主題: 營救鯨魚學(xué)科素養(yǎng):人與自然難度系數(shù):★★★【語篇導(dǎo)讀】在澳大利亞的塔斯馬尼亞島,大約270頭領(lǐng)航鯨擱淺。這是近年來最大的擱淺事件。本文主要介紹了鯨的現(xiàn)狀及人們?yōu)檎撒L所作的努力。
270 Pilt Whales Stranded in TasmaniaArund 270 pilt whales(領(lǐng)航鯨) were stranded① after swimming int shallw② water ff the island f Tasmania in Australia.This is the largest whale-stranding event in years.Peple are wrking hard t save the whales,but at least 90 have died.Every year,arund 2,000 large sea animals,such as dlphins and whales,die by swimming nt a beach r int water that’s t shallw fr them t escape.
This is knwn as “stranding” r “beaching”.Pilt whales and killer whales are sme f the mst cmmnly stranded whales.The current stranding is the largest in Tasmania since 1935.The whales were discvered n Mnday in three different grups-tw grups f abut 30 and ne grup f ver 200.
Rescue wrkers are trying t “reflat” the whales s they can swim away.The jb is especially challenging because the whales are s large.Pilt whales can grw up t 23 feet (abut seven metres) lng and can weigh up t 5,000 punds (abut 2,300 kilgrams).【1】T reflat the whales,they are mved nt a sling③,which allws the rescuers t drag the whales t deeper water. 【2】Many f the whales stranded in Tasmania are in areas that are hard t reach,s it’s hard t get t them with a sling.
Abut 40 wrkers are handling④ the wrk,alng with rughly 20 experienced vlunteers.S far,arund 25 animals have been rescued.Since the rescued whales are likely t return t the place where thers are in truble,wrkers are trying t make sure that rescued whales dn’t get stranded again.Still,abut 90 whales have died s far.Rescue effrts are likely t cntinue fr the next few days.Scientists dn’t fully understand why beachings happen,but they have sme ideas.
It’s pssible that the animals lse their way when they are swimming quickly and fcusing n smething else,like chasing fish r trying t escape⑤ while being chased⑥.Whales and dlphins travel tgether in grups.They wrk tgether clsely,and the grup members generally fllw the leader.When the leader gets beached,it can lead t ther animals getting stranded as well.It’s knwn that a single animal may beach itself if it’s sick r injured.It’s pssible that when grups f whales get stranded,they may be fllwing,r trying t prtect an animal that’s unwell.
①strand /str?nd/ vt.使擱淺;使陷于困境②shallw /'??l??/ adj.淺的;膚淺的③sling /sl??/ n.吊索④handle /'h?ndl/ vt.處理;對付⑤escape /?'ske?p/ v.逃避;避開;避免⑥chase /t?e?s/ vt.追逐;追捕
【1】T reflat the whales,they are mved nt a sling,which allws the rescuers t drag the whales t deeper water.分析:本句中的“T reflat the whales”是動詞不定式作目的狀語。“they are mved nt a sling”是句子的主句部分。后面的which引導(dǎo)非限定性定語從句,修飾前面的名詞sling。譯文:為了讓鯨魚重新浮起來,它們被轉(zhuǎn)移到一個吊索上,這樣救援人員就可以把鯨魚拖到更深的水里。
【2】 Many f the whales stranded in Tasmania are in areas that are hard t reach,s it’s hard t get t them with a sling.分析:本句是由并列連詞s連接的兩個并列句。在前面的分句中,“stranded in Tasmania”是動詞的-ed形式短語,在句中作定語,修飾前面的復(fù)數(shù)名詞whales。而“that are hard t reach”則是定語從句,修飾前面的復(fù)數(shù)名詞areas。譯文:很多鯨魚在塔斯馬尼亞島擱淺,這個地方很難靠近,所以很難用吊索把它們吊起來。
