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.
答案：(A) survived
survive 是及物動詞，直接接所經歷的災難，survive the mass killing 意為「從大屠殺中存活下來」；recover 需要接 from，transformed（轉變）、endangered（危及）語意也不合。
答對率 27%。
survive 你大概認定它是不及物動詞，要說「從災難中活下來」就寫成 survive from——這是最常見的錯誤。它是及物動詞，後面直接接那場災難，不加介系詞：The front passengers were lucky to survive the accident.（前座乘客能在車禍中生還算是幸運）。
真正需要 from 的是 recover：recover from an illness（從疾病中康復）。兩個字都在講「劫後」，一個及物、一個接 from。
句首 Though it was once known… for the 1994 tribal conflict（雖然曾以一九九四年的部族衝突聞名）是讓步；下一句 Now it is healing and prospering（如今正在復原、繁榮）是最直接的印證——挺過來了才談得上復原。
survive the war／accident（在戰爭／車禍中生還，及物不加介系詞）、survive on（靠…維生）、recover from（從…康復）、be survived by（遺有…在世）。
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.
