--I don’t have a partner to practice English_____.
--Why not join an English language club to practice_____?
A./; speaking
B.with; to speak
C./; to speak
D.with; speaking
答案:D
I (主语) don’t have(谓语) a partner(宾语) to practice English with(句中的不定式作定语修饰a partner),词组是practice sth. with sb.和谁干什么事,故with不可省;practice doing sth 是固定短语。故选D。
