选择A

　　原因：这句话是宾语从句,选项所需是做从句结构的句子,而从句必须是用陈述语气的,所以选择A

　　附加宾语从句语序说明：1)一般情况下,即使是有疑问词,从句仍然是陈述句式,如;

　　ThisbookwillshowyouwhatthebestCEOsknow.

　　Canyoufigureoutwhatthepoetreallymeansinthispoem.

　　2)但个别宾语从句本应用陈述语序,可由于习惯而保持原疑问语序不变,如;

　　Idon'tknowwhatisthematterwithhim.

　　Ihavenoideawhatwasthematterwithhim.

　　关于matter的从句都是疑问语序

　　基本上说Idon'tknowwhatiswrong也是对的,可一般来说都是分成两句讲,如;

　　Idon'tknow.Isanythingwrong?或what'swrongwithyou.

　　3)当主句中的谓语动词表示认为,建议,猜测时,如think,say,guess,suppose,suggest,say,believe,feel,consider等.这时宾语从句的引导词是who,which,what,when,where,how,why,就不能按照正常语序安排,经常会将这类词放在句首.如

　　WhatcoursedoyousayIshouldtakeupthissemester?

　　Whodoyouthinkthepublicmightchooseastheirfavoritesingerthisyear?
