I ___________ to phone her all day, but whenver I phone her, the line is engaged.
A．triedB．had been tryingC．have triedD．have been trying
D

試題分析：從the line is engaged可得知與現(xiàn)在有關(guān)，排除AB，再從時間狀語all day可知動作從過去開始一直持續(xù)到現(xiàn)在還很有可能持續(xù)下去，故使用現(xiàn)在完成進行時。句意：我一整天都在打她的電話，但是無論我什么時候打，電話都占線。
點評：要善于確定句子時態(tài)，可以通過時間狀語確定,還可以根據(jù)上下文來確定.但不能斷章取義，要認真看清題意。
