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 .
答案：(D) in the future
承接前面「已經對生活產生直接影響」，這句延伸談論這些創新未來持續產生的影響，in the future（在未來）符合語境。for a moment（片刻）、at that time（在那時，指過去某時間點）、from then on（從那時起，需要明確過去時間點）都不符合這裡展望未來的語意。
四個選項都是時間片語，你會憑語感挑一個。
空格前是 may also dramatically affect our lives ______（可能還會大幅影響我們的生活）。關鍵在助動詞 may 與副詞 also：may 講的是還沒發生、只是有可能；而同一句前半用的是 have had a direct impact on our everyday lives（現在完成式，已經造成的影響）。前半講已經發生的，後半用 may 講還會怎樣，時間軸自然往後走，所以填 in the future（在未來）。填進去讀成 may also dramatically affect our lives in the future。鑑別度只有 23，是本批最低的一題，但它本身不難：may 指向未來這一點各種程度的人都判得出來，題目自然分不出高低。
for a moment（一會兒）講的是短暫的時間長度；at that time（在那個時候）要指一個已經提過的過去時間點，但 may 講的不是過去；from then on（從那時起）同樣要有一個過去的起點，這一句沒有。
in the future（在未來）、in the near future（在不久的將來）、for a moment（一會兒）、from then on（從那時起）、have an impact on（對……造成影響）、take something for granted（把某事視為理所當然）。

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.
