Lizards, 33 can change the color of their skin and 34 the trees and leaves around them. 35 , they cannot be detected by other animals that threaten them.
答案:(A) blend with
【句型】blend with 固定片語「與……融為一體」,表示蜥蜴變色後融入周圍環境;differ from(不同於)、gaze upon(凝視)、migrate to(遷徙到)都不符合「融入環境」的語意。
本題大考中心未公布逐題答對率,以下不談數據,只談觀念。
四個選項都是動詞片語,中文差很遠,照理不難分;但如果只讀空格所在的這半句,會看不出蜥蜴變色到底是為了什麼,四個動作聽起來都像牠可能會做的事。這一格的依據在下一句。
四個選項都是動詞片語,可見這一格考的是語意與搭配。先看結構:Lizards can change the color of their skin and ___ the trees and leaves around them.and 連接兩個動作:改變膚色,以及對周遭的樹木與葉子做某件事。再往後讀一句:they cannot be detected by other animals that threaten them.(牠們沒辦法被威脅牠們的動物發現。)——變色之後之所以不會被發現,是因為牠們與周遭的環境融為一體了,所以填 blend with(與……融為一體)。blend 本來的意思是「混合」,blend with 就是「混進去、融入」,同一組還有 blend in(融入環境、不顯眼)。
differ from(不同於):方向完全相反,與環境不同就更容易被發現了。gaze upon(凝視):蜥蜴變色不是為了盯著樹葉看。migrate to(遷徙到):講的是長距離移動,與「改變膚色」這個動作接不起來,也解釋不了為什麼不會被發現。
blend with(與……融為一體)、blend in(融入環境)、differ from(不同於)、be detected by(被……偵測到、被發現)、threaten sb(威脅某人)、change the color of(改變……的顏色)。
