核心问题
（A）The mercury column measured the height predicted. (A Course in Basic Scientific English, p.13)
(B) He has had the length of the wings increased so that they now measure 93 feet—almost as long as those of a Dakota. (New Concept English, Book 2, L.66)
我认为句(A)中的 measured 应改为 was measured, 句(B)中的 measure 应改为 are measured。请比较：
-
We measured the distance. 我们测量了距离。
-
We measured the room. 我们测量了房间。
