( ) 9. --- I often chat with my friends on the Internet.
--- You are so smart. Will you please tell me ________? (2011青岛)
A. how to do B. how to do it
C. how to use D. when can I use it
为什么选B不选其他的

Answer 1

答案：B 解析：tell me后接宾语从句，宾语从句要用陈述句语序，由此排除D（此项是疑问句语圆盯序）。又do和use是及灶尘物动词，后应橘辩和接宾语，才能与how(副词）连用，因此排除A和C；只有B项中的do有宾语it，故可与how连用。故选B项。

Answer 2

你好~ 因为A C都缺乏谓语， 也就是缺少it D的意思不对。。。。
