尊敬的老师，学生想咨询一下than后面可以直接加if从句吗? 就比如这句话：
These shares may fetch less than if their owners had waited for their employer to go public.
这些股票的价格可能低于其所有者等到其雇主上市时的价格。
在than后面可以直接加if从句。如：
than if ... 比起...... 更 ...... She feels much happier living alone than if she were with her husband. 她觉得单身生活比和丈夫在一起更幸福。（摘自《英汉多功能词典》）
