问题补充:
On our arrival, we found Tom at the desk and a letter.
A. seated, wrote
B. sitting, written
C. seating, writing
D. seated, writing
答案:
A. seated, wrote
B. sitting, written
C. seating, writing
(答案→)D. seated, writing
解析:考查宾语补足语用法。Seat是及物动词(使…就坐);sit是不及物动词(就坐);seated是形容词,在句子中做宾语补足语,说明Tom的情况。第一空也可以使用sitting.Tom和write构成主动关系,所以使用现在分词的形式。句意:我们一到达,就发现Tom在桌子旁边在写信。
