The parrot was 21 , there was no other bird like him in the whole world.
答案：(B) unique
語意「這隻鸚鵡是獨一無二的」，unique（獨特的）呼應後半句「世界上沒有像他一樣的鳥」；lonely（孤獨的）、sorrowful（悲傷的）、personal（個人的）都不符合這個「獨一無二」的語意脈絡。
本題大考中心未公布逐題答對率，以下不談數據，只談觀念。
四個選項都是形容詞，中文差很遠（孤獨、獨特、悲傷、個人的），照理不難分；難的是如果只讀空格所在的半句，會覺得「這隻鸚鵡很孤獨」也講得通。這一格的依據就在同一句的後半段。
四個選項是四個不同的形容詞，可見這一格考的是語意，那就往後讀。空格後面緊接著就是 there was no other bird like him in the whole world（全世界沒有第二隻鳥像他一樣）——這句話等於把答案直接寫出來了：獨一無二，填 unique（獨特的、獨一無二的）。這一招在敘事類的文章裡特別好用：作者常常先給一個評價，緊接著再用一句話解釋那個評價，所以填不出來時先往後讀一句。
lonely（孤獨的）：整篇講的是鸚鵡學不學得會說話，沒有任何一句提到牠寂寞或沒有同伴。sorrowful（悲傷的）：同樣沒有依據，而且與後半句的「世上沒有第二隻」對不起來。personal（個人的、私人的）：用來講屬於某個人的事物，形容一隻鳥不通。

There was once a man in Puerto Rico who had a wonderful parrot. The parrot was 21, there was no other bird like him in the whole world. He could learn to say any word-- 22 one. He could not say the name of his native town, Catano.
The man 23 everything he could to teach the parrot to say "Catano," but he never 24. At first he was very gentle with the bird, but gradually he lost his 25. "You stupid bird! 26 can't you learn to say that one word? Say 'Catano' or I'll kill you!" But the parrot would not say it. Many times the man screamed, "Say 'Catano' or I'll kill you!" But the bird would not 27 the name. Finally the man gave up. He picked up the parrot and threw the bird into the chicken house.
In the chicken house, there were four old chickens, waiting to be killed 28 Sunday's dinner. "You are even more stupid than the chickens," the man said as he was leaving. The next morning, the man went out to the chicken house. When he opened the door, he was 29 by what he saw. He could not believe his eyes and ears! On the floor 30 three dead chickens. The parrot was screaming at the fourth, "Say 'Catano' or I'll kill you!"
