eat 的12种时态：原型式、进行式、完成式、完成进行式分别对应着——现在、过去、 未来。
形式 现在 过去 未来
eat I eat (she eats) I ate I will eat
ing I am eating I was eating I will be eating
have I have eaten I had eaten I will have eaten
have been I have been eating I had been eating I will have been eating
原型式中的三种时态应用的变化。
现在式时态的三种应用：
1，说明事实的。如：Time is money.
2，说明习惯的。如：She goes to school every day.
3，说明现在代替未来（用于副词子句内）的。如：When you come heer tomorrow ,I will tell you.
过去式时态的四种应用：
1，说明一件事时间清楚的，用过去式。如：I eat rice.
2，说明一件事时间不确定的，用现在完成。如： I have eaten rice.
3，说明两件事同时发生的，用过去进行式。如： I was eating rice.
例如：When you tall me yesterday, I was eating lunch.
4，说明两件事先后发生的，用过去完成式。如： I had eaten rice.
例如：When you tall me yesterday, I had eaten lunch.
未来式时态的三种应用：
1，说明一件事时间清楚的，用未来式。如：I will eat rice.
2，说明两件事同时发生的，用未来进行式。如：I will be eating rice.
例如：When you see me tomorrow, I will be eating lunch.
4，说明两件事先后发生的，用未来完成式。如：I will have been eating rice.
例如：When you see me tomorrow, I will have been eating lunch.
现在进行式时态的两种应用：
1，是说明现在正在做的。如： I am eating rice.
2，是说明这段期间正在做，未来预定之行程。例如：She is reading a novel,this week.
例如：The meeting is taking place, tomorrow.（说明是不可以更改的）
现在完成式时态的三种应用：
1，是说明已经做了的。如： I have eaten dinner.
2，是说明曾经做了的。如： I have called him many time.
3，是说明一直都在做的。如：I haved live here for ten years（只是说明在此刻以前一直住在这里，而没有交代下一刻会怎样）所以就有了下面的：
现在完成进行式：如：I have been eating rice.（说明从前做到现在，也将一直做下去）
例如：I have been working here for 3 years.
过去完成进行式：如：I had been eating rice.（说明从以前做到以前某时段，也将一直做下去）例如：I had been working here for 2years, when you came.
未来完成进行式：如：I will have been eating rice.（说明做到未来某时，还将一直做下去）
例如：I will have been working here for 4years, next year.
主词前，可能有副词即两句合并的结构：
构造——……主词……动词，受词或补语。
例如：I watched the movie again,actually I had watched it five imes already.
例如：By the end of this year,I will have been practicing the piano for five years already.
如两句合并的结构：Having make up my mind,I am living this June.用这样的句式来说明：未来预定之行程。
