Question

【題目】 at the back of the classroom several old professors, listening attentively to the new teacher.

A. Seated; were B. Seating; was

C. Sat; were D. Sitting; was

Answer 1

【答案】A

【解析】考查過(guò)去分詞和主謂一致。句意：坐在教室后面的是幾位老教授，正在認(rèn)真地聽(tīng)新老師講課。several old professors是句子主語(yǔ)，復(fù)數(shù)形式，謂語(yǔ)動(dòng)詞用were；be seated坐下，表示地點(diǎn)的狀語(yǔ)位于句首，句子用全部倒裝，過(guò)去分詞提前，故選A。
