( )Well,that was a long time ago,but I still hear his word( )in my ears.

为什么要用现在进行时？？

( )Well,that was a long time ago,but I still hear his word( )in my ears.
A ringing Bsaying Cfalling Dcoming

A
我是用排除法做的，say的主语应该是人，或者牌子、告示之类的东西。CD应该不会是。答案是不是A？
至于你问为什么用现在进行时，看下面的就懂了：
hear/see/watch/notice/observe/find/feel/look at/listen to + sb./sth. + do/doing/done

do强调的是（看到/听到……）全过程
doing强调的是（看到/听到……）正在做
done是被动

“see sb. do”的被动是“sb. be seen to do”
“see sb. doing”的被动是“sb. be seen doing”
“see sth. done”的被动是“sth. be seen done”
“make sb. do”的被动是“sb. be made to do”
