Question

They thought __________ important to look right and left when ________ the road.

A．it’s; cross

B．it; to cross

C．it; crossing

D．it was; to cross

Answer 1

C

試題分析: 句意：他們認(rèn)為過(guò)馬路時(shí)向左右看非常重要。cross 橫穿；they主語(yǔ)，thought謂語(yǔ)，it形式賓語(yǔ)，真正的賓語(yǔ)為to look right and left;when crossing the road當(dāng)過(guò)馬路時(shí)，疑問(wèn)詞+現(xiàn)在分詞做伴隨狀語(yǔ)；故選C。
