Any goldfish lover who hopes to strike up a conversation with their pet goldfish is 15.
答案：(A) out of luck
out of luck（沒有希望的／注定失望的）表示想跟金魚聊天的人注定要失望，因為金魚聽力雖好但不會發出聲音；in the dark（不知情）、off the record（非正式的）、on the rise（上升中）均不符合此處語意。
四個選項都是介系詞開頭的片語，中文都能說成「處於某種狀態」，你會覺得每一個好像都放得進去。
答對率四成。四個選項都是介系詞片語、都能接在 be 動詞後面當補語，形態上刷不掉，這一格考的是認不認得這幾個片語各自的意思。be out of luck 是「運氣不好、這下沒指望了」，用來對一個抱著期待的人說「你要失望了」。這一句的主詞正是那種人——any goldfish lover who hopes to strike up a conversation with their pet goldfish（任何一個想跟自己的寵物金魚攀談的人）。填進去讀成 is out of luck（就要失望了）。緊接著的下一句 Goldfish have excellent hearing, but they don't make any sound whatsoever（金魚聽力極好，卻完全不出聲）正是在說明為什麼沒指望，可以拿來驗算。
in the dark（被蒙在鼓裡、不知情）講的是消息沒被告知，但這一句的人並不是不知情，他是想做一件做不到的事；on the rise（正在增加、上升中）的主詞要是數量或趨勢，不會是人；off the record（私下說的、不可公開引述）用在講話的場合上，與想跟魚聊天無關——注意它的冠詞是齊的，形態上挑不出錯，只能靠語意判斷。
be out of luck（運氣不好、沒指望了）、strike up a conversation（攀談、搭話）、in the dark（被蒙在鼓裡、不知情）、on the rise（正在增加）、off the record（私下說的、不可公開引述）、not ... whatsoever（絲毫不、完全沒有）。
The undersea world isn't as quiet as we thought, according to a New Zealand researcher. Fish can "talk" to each other and make a range of 11 by vibrating their swim bladder, an internal gas-filled organ used as a resonating chamber to produce or receive sound.
Fish are believed to speak to each other for a number of reasons, such as to attract mates, scare off predators, or give directions to other fish. Damselfish, for example, have been found to make sounds to scare off 12 fish and even divers. Another discovery about fish sounds is that not all fish are 13 "talkative." Some species talk a lot, while others don't. The gurnard species has a wide vocal repertoire and keeps up a constant chatter. Codfish, 14 , usually keep silent, except when they are laying eggs.
Any goldfish lover who hopes to strike up a conversation with their pet goldfish is 15 . Goldfish have excellent hearing, but they don't make any sound whatsoever. Their excellent hearing isn't associated with vocalization.
