【问】 (a) After Mr Wimpenny had the plane built，it was tested thoroughly.
 (b) Since then，Mr Wimpenny has had it rebuilt.
 (c) He has had the length of the wings increased so that they now measure 93 feet...
 以上三句摘自New Concept English，Book 2。下面是朗文出版公司、世界图书出版公司出版的《新概念英语》(2)(P.278)上的译文：
 (a) 在Wimpenny请人制成这架飞机之后，又对它进行了全面的试验。
 (b) 后来，Wimpenny让人把它重新改制了。
 (c) 他把机翼的长度增加到93英尺……
 据我所知，have sth. done是指“让人做某事”，例如，I had my hair cut yesterday.(昨天我(让人给我)理了发。)不知为什么译文(c)没有把这层意思翻译出来。
 【答】 have sth. done这个句型常常是有歧义的。有时是指叫别人做某事，而有时则是指主语
 (或逻辑主语)本身做某事。当句子本身不能提供判断线索时，只能求助于上下文。根据NewConcept English，Book 2，L. 66的内容，可以看出，Wimpenny既是自行车飞机的设计者，又是它的制造者，所以，他自己动手干的可能性是极大的。因此，把上面三句中的动作(built，rebuilt，increased)看作是主语发出的动作比较合乎情理。此外，NCE的编者提供的改写练习似乎也证明了这一点。
 (a) After Mr Wimpenny built the plane，it’was tested thoroughly.
 温彭尼先生制造这架飞机后，对它进行了全面的试验。
 (b) Since then，Mr Wimpenny has rebuilt it.
 从那以后，温彭尼先生对这架飞机进行了改建。
 (c) He has increased the length of the wings……
 他增加了机翼的长度……
