Which would you wear to a football game, a sweater or a raincoat? 26 the raincoat if you thought there was a good chance of rain.
答案：(A) Probably
這是省略句修辭，Probably 承接前一句的問句「你會穿什麼？」，省略了主詞和動詞（you would wear），直接以 Probably the raincoat 簡答「大概會穿雨衣」，符合口語化的簡答語氣。Formally（正式地）、Similarly（同樣地）、Consequently（因此）都不符合這種「簡答可能性」的語意。
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 -ly 結尾的副詞，中文擺進去好像都能講，於是憑語感挑；Consequently（因此）特別誘人，因為它看起來最像在承接前面那一句。真正卡住人的其實不是選項，是這一格所在的句子根本不完整——它沒有主詞也沒有動詞，只有一個副詞加一個名詞 the raincoat，會讓人懷疑自己是不是讀漏了什麼。
先回頭看前一句：Which would you wear to a football game, a sweater or a raincoat?（去看美式足球賽，你會穿毛衣還是雨衣？）這是一個問句，而空格所在的這一句正是它的答句。英文的答句可以只留下真正回答問題的部分，與問句重複的主詞和動詞一起省掉；把省掉的補回來就是 You would probably wear the raincoat if you thought there was a good chance of rain.（如果你覺得很可能下雨，你大概會穿雨衣。）這種簡答國中就練過：Do you like it? — Yes, I do. 答句不必把 like it 再說一次。既然這一格是在回答「會穿哪一件」，要填的就是一個表示可能性的副詞，Probably 正好。要注意的是，這一格不看前一句就定不了案——單看 ___ the raincoat if you thought...，四個副詞在形態上都放得進去。
Consequently（因此）要求前面是一個原因，但前面是問句，問句當不了原因；Similarly（同樣地）要求前後兩件事同向並列，前面只問了一個問題，沒有第一件事可以「同樣」；Formally（正式地）講的是方式，回答「穿哪一件」時說「正式地雨衣」不成話。三個選項都接不上「回答可能性」這件事。
probably（大概、很可能）、a good chance of ＋ 名詞（很有可能……）、consequently（因此）、similarly（同樣地）、formally（正式地）、簡答時可以把與問句重複的主詞和動詞一起省略

28 of us can be perfectly sure about how things will turn out in the future. But we can, and often do, think of the possibilities. We can try to guess 29 this or that might happen.
In some cases mathematics can help make these guesses more accurate. The branch of mathematics that helps make our guesses more accurate is called probability. Probability is the science of 30. It is among the fastest growing and most useful parts of today's mathematics.
