The little boy is dirty from head to foot because he ___ in the mud all morning.        
A．has playedB．is playingC．has been playingD．was playing
C
考查時(shí)態(tài)。根據(jù)時(shí)間狀語(yǔ)all morning說(shuō)明是指在過(guò)去一段時(shí)間里一直發(fā)生的事情，故使用現(xiàn)在完成進(jìn)行時(shí)，表示動(dòng)作的持續(xù)性和反復(fù)性。句意：這個(gè)小男孩從頭到腳都是臟的，因?yàn)檎麄�(gè)早晨他都在淤泥里玩耍。故C正確。
