We canceled the performance because one of our members ______ sick. 我們取消了演出,因為我們其中的一名成員生病了。 a. be b. was c. are d. were Explanation 本句because引導的副詞子句中,主詞為one of our members,缺少動詞。one of + 複數名詞表示「這些東西的其中一個」,是單數;且此為一件已經發生過的事,故動詞用過去式be動詞was,正確答案為B。 Chinese translation After leaving this page, need to use 1 more coin to play audio Sorry!
