Their relaxing bath will be 17 a full fluff dry and brush-out.
答案：(B) followed by
be followed by 是「接著是、隨後是」，本句指洗完澡之後接著是全套吹乾與梳理；be counted on（被依賴）、be turned into（被變成）、be started with（說法不自然）都不合。
follow 你大概只記得「跟隨、追蹤」（follow me、follow the rules），沒把 be followed by 當成一個表示先後的固定用法記住。A is followed by B 的意思是「A 之後接著就是 B」——主詞是先發生的那一件事，被動語態容易讓人前後顛倒。
先看選項：四個都是「動詞 + 介系詞」的被動形，在文法上均可成立，可見這一題考的是片語的意思。作答線索在同段前後兩句：前面是 all the dogs are given a bath using professional shampoo and conditioners in a massaging tub（先在按摩浴缸裡以專業洗劑與潤絲精洗澡），後面是 When you arrive for pick-up, your dog will be well-exercised and beautiful（飼主前來接回時，狗已整理得乾淨漂亮）。本段描述的是寵物美容的服務流程，洗、吹、梳依序進行，空格前的 Their relaxing bath 與空格後的 a full fluff dry and brush-out 之間是先後關係，故應填 followed by。凡是描述流程、步驟或行程的文章，空格多半考先後關係，判斷步驟相同：先確認空格前後各是一件什麼事，再判斷兩者的關係。as follows（如下）、the following day（隔天）與本題同屬一組，核心均為「在後面接著出現」。
be counted on 意為「被依賴、被指望」（You can count on me.）；be turned into 意為「被變成」，沐浴與吹毛之間並非變化關係；be started with 非英文的自然說法，正確用法為 start with sth（以…開始）。
A be followed by B（A 之後接著 B）、as follows（如下）、the following day（隔天）、count on sb（指望某人）、start with（以…開始）。
