(1) _________ the road round to the right, she found his house. A. Follow????????????????? B. Following????????????? C. To follow??????????? D. Followed此題應(yīng)選B，現(xiàn)在分詞短語表時(shí)間。(2) _________ the road round to the right, the blind man asked a boy to guide him.A. Follow????????????????? B. Following????????????? C. To follow???????????
