The small portions were designed to merely “touch the heart,” as the name literally means, and 19 were first enjoyed as snacks.
答案：(B) as such
as such 在此意為「正因為如此、基於這樣的性質」，承接前面「分量小、只為 touch the heart」的說明，帶出「因此最早是當點心吃的」；if so（如果是這樣）、by then（到那時）、in that（在於…這一點）語意都不合。
答對率 31%，鑑別度 -7：高分群考生答對的比例反而低於低分群。這在難題上並不少見，不代表題目有毛病：對某個用法愈熟的人，愈容易被它帶走。
as such ＝ as + 前面剛提過的那個身分。99 年學測文意選填那篇談足球與團隊精神，講到退役球員時寫道：He (the former player) knows he is a member of society and must behave himself as such.（打過球的人知道自己是社會的一員，就必須以這樣的身分行事。）這裡的 as such ＝ as a member of society——such 是代名詞，代替的是前面剛講過的那個身分，免得整串再講一次。本題同理。你多半把 as such 拆成「像這樣」，讀不通就換條路走；底子好的人反而容易改挑 in that（因為，比 because 正式）。卡住的地方不是字義，是沒察覺話被縮短過。
and 後面直接就是 were，主詞不見了——它跟前半句共用 The small portions（那些小分量的點心）；such 代替的則是 small portions designed to merely touch the heart（只為「點到心意」而設計的小分量）。還原成完整版：and, [being small portions meant only to touch the heart], they were first enjoyed as snacks。話一還原，as such ＝「正因為具備這樣的性質」就出來了。再用結構確認一次：in that 後面一定要接完整子句——It is a good plan in that it saves money.（這計畫很好，因為能省錢）；本句空格後直接是 were，沒有主詞，in that 進不來。這種「話被縮短過」你背過：When in Rome, do as the Romans do.（入境隨俗）——When 後面省掉了 you are，第二個 do 也不是真的在做什麼，它代替前面那個 do。同一個用法另見文意選填站 99 年第 37 題。
if so（如果是這樣）用於假設，本句是既成事實；by then（到那時）需要兩個能比先後的時間點，本句沒有；in that 敗在結構。
as such（正因為如此、以這樣的身分）、behave oneself（行為得體）、such as（例如）、in that + 子句（因為，比 because 正式）。
The history of dim sum stretches back to the early days of the Silk Road, an ancient network of trade routes connecting the East and the West. Those who traveled along the routes through China needed places to rest. Teahouses thus sprang up to 16 the weary travelers, offering them a cup of tea to help them regain energy. But the culinary art of dim sum 17 , for it was considered inappropriate to pair tea with food.
Centuries later, the ability of tea to aid in digestion finally became known. Teahouse owners therefore began providing bite-sized snacks as an accompaniment, and the tradition of these Cantonese delicacies was born.
Dim sum is more than just an example of Chinese cuisine. It is 18 an enjoyable dining experience that can span hours. The small portions were designed to merely "touch the heart," as the name literally means, and 19 were first enjoyed as snacks. The small size allows the customer to order a great variety of dishes, creating a banquet of different tastes and flavors. It is customary for big groups to enjoy simple dishes together as 20 . Ultimately, dim sum—the food—is only a small part of the dim sum experience.
