This is not what you want, is it?

Test sites: regular polygons and circles; Coordinate and graphic attributes; The essence of rotation.

Special topic: ordinary type.

Analysis: First, connect A ′ d, intersection point F ′ and E ′ to make F ′ g ⊥ A ′ d and E ′ h ⊥ A ′ d, get the coordinates of A ′ from the properties of regular hexagon, and then draw a conclusion according to that every six unit lengths are exactly equal to the regular hexagon.

Solution: Solution: As shown in the figure:

When a unit length is scrolled, the corresponding points of E, F and A are e', f' and a', respectively, connecting a'd, and the points f' and e' are F'g⊥A'd, E'h⊥A'D, respectively.

Hexagonal ABCD is a regular hexagon,

∴∠a′f′g=30，

∴A'G=A'F'=, similarly, HD=,

∴a′d=2，

∫D(2，0)

∴a′(2,2),od=2，

When a regular hexagon rolls for 6 unit lengths, it only rolls once.

∴ Roll exactly 43 unit lengths from point (2,2) to point (45,2),

∵=7… 1,

Just rolled for more than seven weeks,

Point B will pass through point (45, 2).

So the answer is: B.
