Herds of goats and cows 26 enormous horns graze the lush green fields.
答案：(B) with
with 表示「有著……特徵的」（goats and cows with enormous horns＝長著巨大犄角的山羊和牛）；into／for／from 都不合這個修飾用法。
with 這個字，你的印象大概只有兩個意思：「和……一起」和「用……工具」。這兩個意思套進 Herds of goats and cows ___ enormous horns 都不通，於是你反而會去找別的選項，把真正的答案跳過去。落差就在這裡：with 還有一個從國中就學過、但很少被說破的用法 —— 表示「具有某項特徵」，劍橋詞典直接把這個義項解釋成 having。97 年第 26 題也考過 with，不過那一題是 with ＋ 受詞 ＋ 受詞補語（表附帶狀態），句型比較長；本題是最單純的 with ＋ 名詞，兩題可以擺在一起，把 with 的兩種考法一次分清楚。
先數句子成分，這一步就能定案。Herds of goats and cows ___ enormous horns graze the lush green fields. 主詞是 Herds of goats and cows，動詞是 graze，受詞是 the lush green fields —— 主要成分已經齊了。既然齊了，___ enormous horns 這一段就只能是修飾語，而且緊貼在主詞後面，是在後位修飾主詞。能後位修飾名詞、又表示「具有某特徵」的介系詞就是 with。還原成關係子句驗算：cows with enormous horns 等於 cows that have enormous horns（有著巨大犄角的牛）。這個「with 等於 having」的還原做過一次，國中的兩個老例句就全部串起來了 —— the girl with long hair（長頭髮的女孩）、a house with a red roof（有紅屋頂的房子），句型和本題一模一樣，只是換成牛和角。
into（進入）：表示方向或轉變，像 walk into the room（走進房間）、turn into a butterfly（變成蝴蝶）；牛「進入巨大犄角」不成話。for（為了、給）：表示目的或對象，cows for enormous horns 會被讀成「為了取角而養的牛」，可是這一段是在寫眼前的風景（成群的牛羊在青翠草地上吃草），不是在講用途。from（從……來）：表示來源或出處，cows from enormous horns（來自巨大犄角的牛）語意不通。
the girl with long hair（長頭髮的女孩）、herds of cattle（成群的牛）、graze the fields（在田野上吃草）、run into somebody（偶然遇見某人）、be famous for（以……聞名）、lush green（蒼翠繁茂的）
Whenever I set foot on the soil of Rwanda, a country in east-central Africa, I feel as if I have entered paradise: green hills, red earth, sparkling rivers and mountain lakes. Herds of goats and cows 26 enormous horns graze the lush green fields. Although located close to the equator, Rwanda's "thousand hills," 27 from 1,500 m to 2,500 m in height, ensure that the temperature is pleasant all year around. And being a tiny country, everything in Rwanda is 28 in a few hours and the interesting spots can be explored comfortably in a couple of weeks.
But 29, Rwanda is a symbol of the triumph of the human spirit over evil. Though it was once known to the world for the 1994 tribal conflict that resulted in about one million deaths, Rwanda has 30 the mass killing. Now it is healing and prospering and greets visitors with open arms.
