          試題分析:英語中表示一段時(shí)間的時(shí)間狀語不能和瞬間動(dòng)詞一起使用,反之表示瞬間的時(shí)間狀語不能是持續(xù)性動(dòng)詞一起使用。本題中all day和ever since都是表示一段時(shí)間的時(shí)間狀語,即可排除AB選項(xiàng)。結(jié)合句意可知上下文都是完成時(shí)態(tài),故選C。
          點(diǎn)評(píng):英語完成時(shí)態(tài)中有瞬間動(dòng)詞與持續(xù)性動(dòng)詞之分,瞬間動(dòng)詞只表示瞬間動(dòng)作,不能和表示一段時(shí)間的時(shí)間狀語連用,反之持續(xù)性動(dòng)詞也是一樣。再?zèng)]有時(shí)間狀語的情況下,就要結(jié)合語境具體分析。
