---Hi, Tracy, you looked tired. ---I am tired. I______the living room all day. A．painted B．had painted C．having been painting D．have painted

Answer 1

C
试题分析：考查时态。根据关键词all
day说明是在过去一段时间里一直在做的事情，故使用现在完成进行时。故C正确。句意：—Tracy，你好，niiT看上去很累。—我很累，一整天我都在粉刷卧室。故C正确。
点评：时态的考查要放在上下文语境中进行，要根据句子所表达的含义来判断。现在完成进行时强调动作的持续性和反复性，通常与all
the
time之类的词连用。
