19 being hailed as one of the crucial figures in defeating the Nazis, Turing was convicted of "gross indecency."
答案：(B) Instead of
【轉折語】句意為「他非但沒有因擊敗納粹的重大貢獻而受到推崇，反而被判有罪」，故用 Instead of（而非）表示強烈對比。Because of（因為）、In addition to（此外）、With respect to（關於）皆不符合此處的反差語境。
空格後面是 being hailed as one of the crucial figures in defeating the Nazis（被譽為擊敗納粹的關鍵人物之一），這是好事，後半句卻是被判罪。很容易先抓到「被譽為英雄」這幾個字，覺得這一句在講他的功績，於是選 Because of，把整句讀成「因為被譽為英雄，所以……」。答對率四成四。
四個選項都是幾個字合起來當一個介系詞用，後面接名詞或動名詞（劍橋 English Grammar Today 的 Prepositions 條目），所以 being hailed 這個動名詞誰都接得住，文法上刷不掉任何一個，可見這一格考的是空格兩邊的邏輯關係，屬於邏輯勾環。把兩邊的方向各標一次：前半是「被讚譽為擊敗納粹的關鍵人物」（正面），後半是「被以嚴重猥褻罪定罪」（負面）。一正一負，而且不只是轉折，是「該發生的沒有發生，發生的是相反的事」。Instead of 正是這個意思，不是 A 而是 B，國中的掛鉤是 Let's walk instead of taking a bus.（不搭公車，改用走的）；注意它整組當一個介系詞用，後面接動詞時一定要用動名詞，題幹裡的 being hailed 正好呼應這一點。填進去讀成「非但沒有被當成英雄看待，反而被定罪」，落差才出得來。同一篇的第 17 題在做同一件事，先給一個很正面的事實再整個翻過來，只是那一格用的是轉承語 Nevertheless，這一格用的是介系詞，兩題可以擺在一起看。
Because of（因為）會變成「因為被譽為英雄所以被定罪」，因果講不通，而且真正的原因前一句已經寫了：他是同性戀者，在當時的英國是罪行。In addition to（除了……之外，還）要求前後同方向、可以累加，但這裡一好一壞，加不起來。With respect to（關於、就……而言）用來帶出討論的主題，放在句首會變成「就被譽為英雄這件事而言，他被定罪」，兩半接不上。
instead of 加 V-ing（不做 A，而是 B）、be hailed as（被譽為）、be convicted of（被判……罪成立）、in addition to 加名詞（除了……之外，還）、with respect to（關於、就……而言）、crucial（關鍵的、至關重要的）
Alan Turing was one of the leading scientific geniuses of the 20th century. Many scholars consider him the father of modern computer science. He was also the man who cracked the 16 uncrackable Enigma code used by Nazi Germany. His code-breaking turned the tide of World War II and helped save two million lives. Nevertheless, 17 people have even heard his name. Turing displayed signs of high intelligence in math and science at a young age. By the time he was 23, he had already come up with the idea of what 18 the modern computer—the Turing machine. Today, Turing machines are still used in theoretical computation. He also proposed the now famous Turing test, used to determine whether a computer exhibits intelligent behavior equivalent to that of a human.
The postwar era, however, was a disaster for Turing. He was gay, which was then a crime in Britain. 19 being hailed as one of the crucial figures in defeating the Nazis, Turing was convicted of "gross indecency." This 20 drove him to commit suicide in 1954, at the age of 41.
Nearly 60 years after his death, Queen Elizabeth II granted Turing a formal pardon for his conviction, upon an online petition signed by prominent scientists and technology leaders around the world.
