----Little Daniel is watering the flowers! Why?
-----Well, I’m not feeling very well today—otherwise I           it myself.
A.didB.would doC.have doneD.will have done
B

试题分析:考查虚拟语气。本题是与现在事实相反的虚拟语气,主句中使用“情态动词+动词原形”;本句的条件是通过副词otherwise必须出来的。句意:—小Daniel正在浇花!为什么?—我今天身体不好。要不然,我会自己做的。根据句意说明是与现在事实相反,故B正确。
点评:要注意条件句以及含蓄条件句的虚拟语气的使用,如果过去事实相反,条件句中使用过去完成时,主句使用“情态动词+have done”;
如果主句与现在事实相反,条件句中使用过去时,be动词使用were,主句中使用“情态动词+动词原形”;如果与将来事实相反,条件句中有三种:过去时;were to do ;should+动词原形,主句使用“情态动词+动词原形”;要特别注意如果省略了if,句子要使用部分倒装的形式,把助动词,be动词,情态动词提之主语前。
