English words are made of 26 letters, and palindromes and anagrams are two kinds of word games about spelling. A palindrome is a word or a sentence that reads the same from left to right or from right to left, （ 本題 ）, "eye," "Bob," "my gym," and "Was it a car or a cat I saw?" An anagram of a word or words is made by putting the letters of the word or words in a different way. Look at the words and their anagrams below. Can you think of other possible anagrams of these words?

Anagrams are often longer words that don't really mean anything but are fun to say. Sometimes they can even mean something （ 42 ）, like when a common word, "restaurant," becomes "Eat rats, run!"
Actually, palindromes and anagrams are （ 43 ）. Palindromes can be used to learn mathematics and make music. Anagrams are also a good way to hide something. In history, people often hid their important studies in anagrams. Can you think of any other way to use them?
克漏字考轉承語時，解法永遠是同一招：看空格前面是什麼、後面是什麼，判斷兩者的關係。空格前是一個定義句，「回文就是正讀反讀都相同的字或句子」。空格後呢？"eye," "Bob," "my gym"，一整排具體的字排隊站好。定義後面接一串實例，這個關係只有一個名字，叫做「舉例」，所以填 for example。做這種題不需要翻譯整篇文章，前後各抓一句、判斷關係，十秒內可以收工。
誘答分析
•
(A) in fact：意思是「事實上」，用來加強或翻轉前一句的說法。它是四個選項裡最有「文章感」的詞，很多人覺得放哪裡都通順就選了它。但定義接例子，不是定義接反轉。
•
(B) at first：意思是「起初」，暗示後面會有一個「後來」。這篇文章此處完全沒有時間先後的對比，選它的人是憑「這個片語我認識」在硬套。
•
(C) of course：意思是「當然」，用來確認一件大家都同意的事。eye 和 Bob 是新登場的例子，不是眾所皆知的舊資訊，語氣接不上。它靠的是「常見、順口」來騙票。
