We can 30 the spirit going by communicating often and consciously.
答案：(B) keep
【句型】keep...going 字詞搭配「讓……持續下去」；push（推）、bring（帶來）、make（使，不太符合這種持續性的表達）都不合。
We can ______ the spirit going 這一格，四個動詞代進去都像有那麼一回事，make 尤其誘人，因為「使這股精神繼續下去」中文唸起來很順。問題是 make 後面接的是原形動詞，不是 -ing。
盯住空格後面的形狀：受詞 the spirit 加上現在分詞 going。能用「受詞加現在分詞」表示「讓某件事持續進行」的動詞是 keep：keep something going（讓某事一直進行下去）（劍橋詞典）。還原成白話就是「讓這股精神持續下去」。句子後半 by communicating often and consciously（經常且有意識地與人溝通）說明維持的方法，也支持「持續」這個語意。這一題其實是在考「動詞後面該接什麼形式」這個大分類，值得一次整理起來：make、let、have 後面接原形動詞（My mother made me clean my room.）；keep 後面接現在分詞（keep somebody waiting）；want、ask 後面要加 to（ask somebody to do）。102 年第 27 題考的正是 have somebody do 的原形，本題考的是 keep something doing 的現在分詞，兩題可以擺在一起看。
push：推、催促，push somebody to do something 後面要加 to，不接現在分詞。bring：帶來，不能用「受詞加現在分詞」這種結構。make：使，後面必須接原形動詞（make the spirit go），加 -ing 不合文法。
keep something going（讓某事持續下去）、keep in touch（保持聯絡）、keep somebody waiting（讓某人等）、push somebody to do something（催促某人做某事）、bring about（帶來、造成）、be more effective than（比…更有效）。
In the fall of 1973, in an effort to bring attention to the conflict between Egypt and Israel, World Hello Day was born. The objective is to promote peace all over the world, and to 26 barriers between every nationality. Since then, World Hello Day—November 21st of every year— 27 observed by people in 180 countries. Taking part couldn't be 28 . All one has to do is say hello to 10 people on the day.
However, in response to the 29 of this event, the concepts of fostering peace and harmony do not have to be confined to one day a year. We can 30 the spirit going by communicating often and consciously. It is a simple act that anyone can do and it reminds us that communication is more effective than conflict.
