112年的篇章組合跟113年值得對照；值得特別挑出來的重點分別是31題跟33題：
31題：第三段的主題句(Topic sentence)
33題：後面接”For example”
因此，可以先從這兩題下手，從而排除32和34的選項。
31
___31___ In the early 1990s [. . .] scientists noticed that synesthetic colors do not change over time.
這兩句話顯然圍繞著「時間」這個主題；或說，跟「過去歷史」相關。從這個面向去回推，可以發現只有選項(C)符合：
(C) People with synesthesia used to be accused of making their experiences up.
另外，也能從句意推敲：
making their experiences up← →however, [. . .] do not change over time.
However 連接兩個句子「相反」的情況。
因此，31題選(C)
33
33 For example, the flavors [. . .] are [. . .] childhood flavors, such as . . . Also, [. . .] have had early musical training.
從舉例的”childhood (stimuli)”和”early musical training” 的線索，可以推論只有選項(B)有「環境影響」(environmental influences)的內容：
(B) Meanwhile, environmental influences seem to shape a person’s synesthesia
因此，33題選(B)
32
32題相對容易解答，因為有選項(A)”consistency”跟原句”persistently”的線索。
上句：synesthetic people would persistently give the same answer . . .
下句：(A) This consistency serves as a proof that . . .
因此，32題選(A)
34
最後，還沒選擇的選項(D)放入34的空格，線索是：
上句： [ . . .] about one to four percent of the population.
下句：(D) Some studies even show that people may all be synesthetic to some degree.
兩句話都有「程度」、「人口比例」的語意，符合銜接性的原則。
因此選(D)
結論
掌握語句之間的銜接性、通篇文章的連貫性，可以幫助考生答題。
