解析
试题分析:考察错综条件句。本题的条件句中是与过去的事实相反,故使用过去完成时,主句是与现在的事实相反,故使用“情态动词+动词原形”;句意:如果在你摔倒的时候,我不在梯子后面扶着你,你现在就不会这样笑了。故A正确。 点评:条件句的虚拟语气是考查的重点。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。另外还要注意条件句和主句不同的时间所形成的挫折条件句。 |
