For example, one study found various differences 27 boys and girls in sensory learning styles.
答案：(C) between
【句型】differences between 字詞搭配「……之間的差異」；for／within／into 都不是 differences 常見的搭配介系詞。
difference 的中文是「差異」，你大概不會特別去想它後面該接哪一個介系詞，反正「在……方面的差異」聽起來 for 或 within 好像也不是不行。這一格其實有一個一眼就看得到的訊號。
四個選項都是介系詞，可見這一格考的是 differences 跟誰搭配。訊號在空格後面：boys and girls 是用 and 連起來的「兩方」，而 between 的本義就是「在兩者之間」，difference between A and B（A 與 B 之間的差異）是國中就背過的組合，掛鉤直接用 What’s the difference between A and B?（A 和 B 有什麼不同？）。看到 and 把兩個對象並排在空格後面，between 幾乎是自動的。順便把範圍分清楚：兩者用 between，三者以上用 among（among the three countries 在這三個國家之中）。
within（在……內部）：講的是一個範圍之內的情況（differences within a group 一個群體內部的差異），這裡要比的是男孩與女孩兩邊，不是某一群人的內部。for：differences 不搭 for，for 帶出的是對象或目的。into：go into、turn into 那一類「進入、轉變成」的動作才用 into，與差異無關。
the difference between A and B（A 與 B 之間的差異）、tell the difference（分辨出差別）、make a difference（造成影響、帶來改變）、make no difference（沒有差別、無關緊要）、among the three（在三者之中）、a difference in style（風格上的差異）。
Learning style means a person's natural, habitual, and preferred way(s) of learning. Research about learning styles has identified 26 differences.
For example, one study found various differences 27 boys and girls in sensory learning styles. Girls were 28 more sensitive to sounds and more skillful at fine motor performance than boys. Boys, 29, showed an early visual superiority to girls. They were, however, clumsier than girls. They performed poorly at a detailed activity 30 arranging a row of beads. But boys excelled at other activities that required total body coordination.
