Question

【題目】The secretary worked late into night, ________ a long speech for the president.

A. to prepare B. preparing

C. prepared D. was preparing

Answer 1

【答案】B

【解析】試題分析：考查非謂語動詞。句意：秘書工作到深夜，在為董事長準(zhǔn)備一個(gè)很長的演講稿。前面一句已經(jīng)有謂語動詞worked，且兩句之間沒有連詞，故判斷空格處用非謂語動詞。根據(jù)邏輯主語The secretary與prepare之間是主動關(guān)系，故要用v-ing形式。故選B。
