資源簡介 2025 秋人教英語八上 單元語法Unit 4 Amazing Plants and Animals形容詞和副詞最高級一、定義:形容詞和副詞的最高級用于比較三個或三個以上的人或事物,表明在某方面“最……”的性質、特征或動作程度。通過最高級,我們能夠明確指出在多個對象中處于最突出地位的那一個,使信息表達更加精確和具體 。比如,“The blue whale is the largest and theheaviest animal in the world.”(藍鯨是世界上最大且最重的動物。)這句話中,“the largest”(最大的)和 “the heaviest”(最重的)就是最高級形式,清晰地表明了藍鯨在動物中體型方面的最突出特點。二、形容詞、副詞最高級的構成:規則變化:(一)一般情況下,直接在形容詞或副詞后 + est。如:“tall”(高的)變為 “tallest”(最高的) ;“fast”(快地)變為 “fastest”(最快地)。(二)以不發音的 -e 結尾的單詞,直接 + st。如:“nice”(好的)變為 “nicest”(最好的);“late”(晚的)變為 “latest”(最晚的)。(三)以 “輔音字母 + y” 結尾的單詞,變 y 為 i,再 + est。如:“happy”(開心的)變為 “happiest”(最開心的);“early”(早地)變為 “earliest”(最早地)。(四)末尾只有一個輔音字母的重讀閉音節單詞,雙寫該輔音字母,再 + est。如:“big”(大的)變為 “biggest”(最大的);“hot”(熱的)變為 “hottest”(最熱的)。(五)部分雙音節和多音節單詞,在單詞前 + most。如:“beautiful”(美麗的)變為 “most beautiful”(最美麗的);“carefully”(仔細地)變為 “most carefully”(最仔細地)。第 1頁共 3頁2025 秋人教英語八上 單元語法不規則變化:有一些形容詞和副詞的最高級變化是不規則的,需要特殊記憶。如:“good /well”(好的 / 好地)的最高級是 “best”(最好的 / 最好地)。“bad /badly”(壞的 / 壞地)的最高級是 “worst”(最壞的 / 最壞地)。“many /much”(許多)的最高級是 “most”(最多的)。“little”(少的)的最高級是 “least”(最少的)。“far”(遠的)的最高級有 “farthest”(最遠的,側重于距離)和 “furthest”(最遠的,可指距離、程度等)。“old” 的最高級有 “oldest”(最年長的,指年齡大小)和 “eldest”(最年長的,常用于表示家庭成員間的長幼順序)。三、形容詞、副詞最高級的用法:(一)三者或三者以上之間的比較基本結構為:主語 + be 動詞 + the + 形容詞最高級 + 表示范圍的短語或從句;主語 + 實義動詞 + (the) + 副詞最高級 + 表示范圍的短語或從句。如:“The cheetah runs the fastest among all land animals.”(獵豹在所有陸地動物中跑得最快。);“I think the most useful plant in the world is bamboo.”(我認為世界上最有用的植物是竹子。)(二)在三者或三者以上中選擇結構為:which/who is + the + 最高級,A, B or C 如:“Which is the most beautiful, the rose, the peony, or the lotus flower ”(玫瑰、牡丹和蓮花,哪一種最美麗?)(三)最…… 之一結構為:one of the +形容詞最高級 +可數名詞復數。如:“Ginkgo trees are one of the oldest living trees on earth.”(銀杏樹是地第 2頁共 3頁2025 秋人教英語八上 單元語法球上現存最古老的樹木之一。)(四)修飾最高級為了更準確地表達最高程度,可以用一些詞或短語來修飾最高級。常見的有 “byfar”(最……;顯然) ,“nearly”(幾乎),“almost”(幾乎)等。如:“This is by far the best movie I've ever seen.”(這顯然是我看過的最好的電影。)(五)同級比較(與最高級相關的特殊情況)在表達 “第二、第三…… 最……” 時,結構為:the + 序數詞 + 最高級。如:“The Amazon River is the second longest river in the world.”(亞馬遜河是世界上第二長的河流。)四、使用最高級時的注意事項:(一)使用最高級時,一定要有表示比較范圍的短語或從句,如 “in...”(在…… 范圍內),“among...”(在…… 之中)等 。如:“He is the tallest in his class.”(他在他的班級里是最高的。)這里 “in his class” 明確了比較的范圍。(二)形容詞最高級前一般要加定冠詞 “the”,但當最高級前有物主代詞、指示代詞、名詞所有格等限定詞時,不加 “the” 。如:“This is my best friend.”(這是我最好的朋友。)(三)副詞最高級前的 “the” 可以省略 。如:“He runs (the) fastest in our school.”(他在我們學校跑得最快。)第 3頁共 3頁2025 秋人教英語八上 單元語法Unit 4 Amazing Plants and Animals形容詞和副詞最高級鞏固練習一、單項選擇1.
