But 29, Rwanda is a symbol of the triumph of the human spirit over evil.
答案：(C) above all
above all 意為「最重要的是」，用來把本句提升到前面所列各項優點之上：盧安達最重要的意義在於它是人類精神戰勝邪惡的象徵；worst of all（最糟的是）語氣負面，for that matter（就此而言）、at most（至多）語意都不合。
答對率 38%。
above 你大概只當它是「在…上方」，所以看到 above all 不知怎麼用。它是一個固定片語，意思是「最重要的是」，用來把最關鍵的那一項從前面列的東西裡挑出來——拆成 above ＋ all 去推反而會卡住。
前面已經列了盧安達的好處：治安、風景、國土小到幾小時就能到處跑。本句用 But ___ 起頭，接著說它是「人類精神戰勝邪惡的象徵」——這是分量最重的一點，所以要用 above all 把它抬到所有優點之上。看到 But 後面跟著空格、前面又列了好幾項，先想 above all 這一類把重點往上推的詞。
above all（最重要的是）、first of all（首先）、after all（畢竟）、all in all（總的來說）、in all（總共）、at all（完全，用於否定）、all of a sudden（突然）。意思彼此無關，只能整組背。
worst of all（最糟的是）語氣負面；for that matter（就此而言）是補充；at most（至多）用於數量。
above all（最重要的是）、first of all（首先）、after all（畢竟）、all in all（總的來說）、at all（完全，用於否定）。
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.
