The most familiar aspect of Tai Chi Chuan is the hand form, which is a series of slow-flowing movements with poetic names 17 “dragons stirring up the wind” and “wave hands like clouds.”
答案：(B) like
介系詞 like 在此表示「例如/像……一樣」，相當於such as，引導後面兩個具體招式名稱（「白鶴亮翅」「雲手」）作為 poetic names（詩意名稱）的舉例說明；from（來自）在這裡文法語意都不通，會變成「名稱來自於這些名稱」，邏輯矛盾；between（在……之間）、regarding（關於）都不合。
like 在你腦中排第一的是動詞「喜歡」，排第二的是「像……一樣」的比較。比較少人注意到 like 當介系詞時可以直接拿來「舉例」，等於 such as。更麻煩的是這一句後面剛好又出現一個 like（wave hands like clouds，雲手），前後兩個 like 意思不同，很容易讀亂。柯林斯詞典在 like 條下就明講：like 可用來引出你剛提到的那一類人事物當中的一個例子，例句是 large cities like New York（像紐約這樣的大城市）。
看空格前後各是什麼。空格前是 poetic names（富有詩意的名稱），是一個上位的統稱；空格後是兩個用引號括起來的實際名稱。「先給一個統稱，再舉底下的具體例子」，中間要填的就是「例如」。驗算方式：把 like 換成 such as 讀一次，意思完全不變 —— poetic names such as “dragons stirring up the wind” and “wave hands like clouds.” 換得動，就對了。這裡可以掛回你早就會的句子：I like sports like basketball and baseball.（我喜歡籃球、棒球這類運動。）同一句裡兩個 like，前面是動詞「喜歡」，後面是介系詞「例如」。本題考的就是後面那個。
from（來自）會變成「這些名稱來自這些名稱」，邏輯打結。between（在……之間）雖然後面確實接了兩個東西，但語意會變成「介於兩個名稱之間的名稱」，講不通；between 要用在真的有「兩端」的情境，例 between Taipei and Kaohsiung（在台北和高雄之間）。regarding（關於）等於 about，多用在公文書信，例 regarding your application（關於你的申請），填進去是「關於這兩個名稱的名稱」，也不合。
like（像；例如）、such as（例如）、for example（舉例來說）、a series of（一連串的）、be familiar with sth（熟悉某事物）、be familiar to sb（為某人所熟悉）、stir up（激起、攪動）。
