As a result, about 95 % of Australia's mammals and 94 % of its frogs are found 30 else in the world.
答案：(A) nowhere
nowhere else 意為「世界上別無他處」，承接前一句「牠們各自獨立演化」的結果——澳洲九成以上的哺乳類與蛙類在其他地方都找不到；somewhere／everywhere／anywhere else 都無法表達這個否定語意。
這題很難，但讀懂的人幾乎都對。
nowhere 是一個「自帶否定」的副詞，句子裡看不到 not，你因此讀不出否定的意思，往往改挑看起來比較安全的 anywhere 或 somewhere。要記住：nowhere ＝ not anywhere，否定已經藏在字裡，句中不需要也不能再加 not。
作答線索在前一句 They evolved separately.（牠們各自獨立演化）。本句以 As a result 開頭，承接的就是這個原因：澳洲與其他陸塊分開之後，動物走上不同的演化路線，結果就是這些物種只有澳洲有、世界其他地方都找不到。看到 As a result、Therefore、Thus 這類表結果的連貫標記，先回頭把原因找出來，再判斷結果的語意方向；這一步做完，四個 -where 只剩一個說得通。這一格光看本句是選不出來的，線索不在空格附近，而在上一句——遇到句首帶連貫標記的空格，養成先往回讀一句的習慣。
somewhere else 是「別的某個地方」，會變成「在世界上別的某處被發現」，與獨有性矛盾；everywhere else 是「其他各處都有」，語意完全相反；anywhere else 通常用於否定句或疑問句（not found anywhere else 才成立），本句沒有 not，單獨用 anywhere 語意不完整。
nowhere else（別無他處）、nowhere to be found（遍尋不著）、get nowhere（毫無進展）、out of nowhere（突然冒出）。
Up to about 250 million years ago the world had just one huge super-continent called Pangaea. Animals were able to move and intermix with 26. About 200 million years ago this super-continent broke up into two continents: Laurasia and Gondwana. About 60 million years ago Gondwana broke up into 27 later became South America, Africa, Antarctica, India and Australia.
Since then Australia 28 from the rest of the world by vast oceans. The animals there no longer had 29 with animals from other parts of the world. They evolved separately. As a result, about 95 % of Australia's mammals and 94 % of its frogs are found 30 else in the world. Australia has lots of very unusual animals.
