It 21 the kind of welcome it has been getting ever since.
答案：(B) was given
被動語態過去式 was given，「它（首演）獲得了從那時起一直持續的熱烈歡迎」（被觀眾「給予」歡迎，被動）；is given（現在式，時態不合，這是講首演那次的過去事件）、has given（現在完成主動，方向不合）、had given（過去完成主動，方向也不合）都不合。
看到後半的 it has been getting ever since（從那時起一直受到），很多人覺得整句要配現在完成式，就挑了 has given。另一個卡點是主動被動：welcome 在這裡是名詞「歡迎」，歡迎是觀眾給的，音樂劇是接受的一方。
先確定時間點。前一句寫得很清楚：On March 23, 1999, the musical MAMMA MIA! made its first public appearance in London.（1999 年 3 月 23 日在倫敦首演）。這一句講的就是首演當晚的事，是一個結束在過去的時間點，所以用過去式。後半的 ever since 反而是線索：既然說「從那時起一直如此」，那個「那時」就是一個過去的點，而本句正是在描述那個點。再判斷語態。give 是「給」，還原成主動就是 The audience gave it the kind of welcome...（觀眾給了它這樣的歡迎）。把受詞 it 提到句首當主詞，就變成 It was given the kind of welcome...。這是課本教過的雙受詞動詞被動：give somebody something 變成 somebody is given something，你國中造過 He gave me a book. → I was given a book. 這一題的鑑別度只有 31，是這一年最低的一題，連高分群考生也大量失手。原因是兩個關卡疊在一起：要同時判斷時態（首演那一刻，過去式）和語態（歡迎是被給予的，被動）。只要其中一個判斷錯就會被帶走，而 has given 對「看到 ever since 就想完成式」的人特別像正確答案。
is given：語態對了，但現在式講的是常態，接不上「1999 年首演那一晚」這個明確的過去時間點。has given：現在完成式而且是主動，方向相反，會變成「音樂劇給了歡迎」。had given：過去完成式而且是主動，方向同樣相反，何況過去完成式需要另一個更早的過去時間點當參照，本文沒有。
