The pineapple, long a symbol of Hawaii, was not a native plant. 21 , pineapples did not appear there until 1813.
答案：(B) In fact
前一句說鳳梨不是夏威夷原生植物，這句「事實上」鳳梨直到1813年才出現在那裡，In fact 承接強調前述事實；For example（舉例）、As a result（因此）、Little by little（逐漸地）都不合。
In fact 你背的是「事實上」，用來補充事實。但四個選項代進去好像都讀得通，這時要看的不是中文翻譯，而是前後兩句的關係。前一句說鳳梨並不是夏威夷的原生植物，空格句說鳳梨直到 1813 年才出現在那裡——後句沒有換話題，而是把前句講得更具體、把話說得更重，這正是 in fact 的功能：承接前句，再給出更強的說法。
這一格必須回頭讀前一句，屬於跨句題。判斷的步驟是先問「後句和前句是什麼關係」：舉例、因果、加強，還是逐步變化的過程？答案是加強，所以填 In fact。同一篇稍後的 From there（從那裡起）也是同一類銜接詞，都在替讀者標示下一句要往哪個方向走，可以一起記。
For example 要求後句是前句的其中一個例子，但這一段從頭到尾只講鳳梨一種植物，沒有「其中一例」可言。As a result 要求前因後果，可是「不是原生種」與「1813 年才出現」是同一件事的兩種說法，不是誰造成誰。Little by little（漸漸地）講的是一個持續變化的過程，本句給的卻是一個確切年份。
in fact（事實上）、as a matter of fact（事實上，與 in fact 同義）、not…until（直到……才）、a symbol of（……的象徵）、a native plant（原生植物）、little by little（漸漸地）
