一整篇文章的例子：剑五P75

To be located in the town centre,S2 is in the town centre, a non-traffic zone. As result, it is only accessibleby the railway whereas the main roads are unavailable. Moreover, it is hemmed out the houses, meaning it’s convenient for the dwellers to do some shopping. In addition, it is closer to the south industry but far away from the north.

Unlike S2, S1 will be set in the countryside, where both the railway and main roads are ready. But the 44000 people from Bransdon and Crandson find it not easy to reach S1, although it is connected by the railway with Crandson. Furthermore, this site is far away from the two industry areas. However, it is convenient for those who live in Hindo.

To sum up, the two sites are different in many aspects/ways.
