失去顏色變成白色，這是珊瑚面臨威脅的一種表現(xiàn)，所以正確答案是珊瑚失去顏色變成白色。4.D)Alloftheabove.解析：文章第三段提到了減少碳排放、實施更嚴格的規(guī)定、開展研究和開發(fā)社區(qū)保護計劃，這些都是為了保護大堡礁而采取的舉措，所以正確答案是所有以上選項。5.B)Theriseinsealevels解析：文章最后一段提到了海平面上升對大堡礁的長期威脅，這是大堡礁面臨的一個重大挑戰(zhàn)，所以正確答案是海平面上升。三、句子匹配題1.E.Inconclusion,thebrainisaremarkableorganthatcontrolsourthoughts,actions,andfeelings.Itscomplexstructureandfunctionsal
