A．had eatenB．ateC．are eatingD．have eaten

分析 -托尼，餅干在哪里？別告訴我你把它們都吃光了！再回答一次!
-是的，我都吃了．我沒忍住，它們太好吃了．

解答 答案：B
根據(jù)答語"Yes，I did"使用了一般過去時(shí)，可知此處的動(dòng)作"eat"應(yīng)是發(fā)生在過去，所以這里應(yīng)使用一般過去時(shí)；故選B．

點(diǎn)評(píng) 本題考查了一般過去時(shí)的用法；做本題時(shí)，應(yīng)根據(jù)答語所使用的時(shí)態(tài)，確定問句的時(shí)態(tài)；另外，還應(yīng)掌握其它各時(shí)態(tài)的意義及用法區(qū)別．
