In creating the list, the group 17 twenty-five non-medically related technological innovations that have become widely used since 1980.
答案：(C) singles out
single out 意為「從一群當中挑選出來（特別關注）」：評選小組從眾多創新中挑出二十五項非醫療類的技術發明；gives in（讓步）、takes over（接管）、turns down（拒絕）語意都不合。
single 在你腦中是形容詞「單一的、單身的」，很難聯想到它能當動詞。single 的動詞義正是「使成為單獨的一個」，加上 out 就成了 single out——把某一個從群體中挑出來，給予特別的關注。
先抓骨幹。主詞是 the group（那個評選小組），空格是主要動詞，受詞是 twenty-five non-medically related technological innovations，後面的 that 子句是修飾受詞的。句首 In creating the list（在製作這份名單的過程中）是分詞構句，交代動作發生的場合。四個選項都是動詞片語，句法上都放得進去，要靠語意決定——而場合已經把方向給了：既然是在「製作名單」，動作必然是從一堆東西裡挑出一部分。驗算法：把分詞構句與主要子句的因果接起來唸一遍——They were making a list, so they picked twenty-five innovations out of many.（他們要做名單，所以從眾多創新裡挑出二十五項。）接得起來，方向就對。single out 褒貶都能用，關鍵在「被挑出來的那一個受到特別對待」：Jamie was thrilled when the teacher singled out his poem and asked him to read it aloud.（老師特別挑中他的詩請他朗讀，他非常興奮。）換成 be singled out for criticism，就是被挑出來挨罵。
三個都是動詞片語，錯在動作方向。give in 是「讓步、屈服」，要用得寫成 give in to sth，後面接的是壓力或要求，而且它是不及物的，不能像本句這樣直接接一個受詞。take over 是「接管、接手」，接的是公司、職務或地盤，把二十五項發明「接管」過來講不通。turn down 是「拒絕」，方向與「製作名單」正好相反——名單是把東西收進來，不是推出去。
single sb／sth out（挑出）、be singled out for praise／criticism（被特別表揚／批評）、pick out（挑出）、give in to sth（屈服於）、take over（接管）、turn down（拒絕；調低）。
Today, with a couple of clicks, you can go anywhere in the world without leaving your computer. So it should come as little 16 that the Internet has headlined the top 25 innovations of the past quarter century, according to a panel of technology leaders assembled to promote inventiveness.
In creating the list, the group 17 twenty-five non-medically related technological innovations that have become widely used since 1980. These innovations are readily recognizable by most Americans, have had a direct impact on our everyday lives, and may also dramatically affect our lives 18.
The top innovation, the Web, was created by British software consultant Tim Berners-Lee. 19 by the multitude of information systems requiring complicated access, Berners-Lee fashioned a universal one that made information readily 20. He created HTML (hypertext markup language) and its rule of usage (HTTP, hypertext transfer protocol). In 1991 he unveiled the World Wide Web. Today, this No. 1 invention has become so commonplace that it is almost taken for granted.
