二、典型例解
( )1.—Kangkang, can I borrow your bike?
— _______
A. I’d love to. B. Thank you. C. Sure. D. You’re welcome.
分析：C 考查表示同意功能的交际用语。Thank you. 是用来答谢对方的语言, You’re welcome.是答谢的应答语,I’d love to. 是回答邀请的。Sure. 在这里的意思为“中国青年作文当然”,表示同意。故选C。

A. it up B. up it C. up them D. them up
分析：D 考查动副词组与代词的搭配。look ... up in the dictionary 意为“查字典”,look是动词,up是副词,代词应在look与up之间,由于words是可数名词复数,独生子女的故应用them。故选D。
