Road running is unique among athletic events because it 17 all ages and abilities.
答案：(A) caters to
caters to all ages and abilities（適合／滿足各年齡層與能力的需求）表示路跑之所以獨特是因為它能兼顧各種年齡與能力的人參與；depends on／goes after／identifies with 均不符合此處語意。
cater 這個字，你的印象大概只有「外燴、供應餐點」（a catering company 是外燴公司），很難想到它有「迎合、滿足某一群人的需求」這個常用義，所以四個選項看起來好像都沾不上邊。答對率四成七。
四個選項都是動詞加介系詞的組合，形態上刷不掉任何一個，可見這一格考的是語意。線索在同一句的 because：Road running is unique among athletic events because it ______ all ages and abilities.，because 引出的是「為什麼獨特」，所以空格要填的是一個能解釋獨特性的動作。下一句立刻把答案講白了：初次參賽的業餘者可以和路跑社團成員、甚至現役的世界級選手同場，有時還包含輪椅參賽者——不分年齡、不分程度都容納得下。cater to somebody 正是「滿足某一群人的需求、迎合某一群人」（劍橋詞典的 cater 詞條），填進去讀成 it caters to all ages and abilities，主詞 it 指的是 road running，第三人稱單數所以動詞加 -s。這個字的兩個意思其實是同一件事：外燴業者得按客人的口味與人數準備餐點，那就是在滿足需求；把餐點抽掉，剩下「按對方的需要來安排」，就是本題的用法。
depends on（取決於、依賴）填進去會變成「路跑取決於所有年齡與能力」，主詞與受詞的關係整個反過來了。goes after（追求、追捕）帶著主動去爭取的意思，一項運動不會去追誰。identifies with（認同、對……有共鳴）的主詞通常是人，講的是心理上把自己與某人放在一起，賽事本身不會產生認同。這一格的鑑別度高達 57，分開的就是認不認得 cater to 的這個意思——三個誘答選項都是你很熟的片語，熟悉度在這裡幫不上忙。
cater to somebody（迎合、滿足某人的需求）、depend on（取決於、依賴）、go after（追求、追捕）、identify with（認同、對……有共鳴）、be unique among（在……當中獨一無二）、all ages and abilities（各年齡層與各種程度的人）
