This is the example of explanation text about how roman roads were built. Although the road was built formerly, in the past time. Explaining on how to make it can be written in present tense mode. It still gives the logical reasons.
Explanation text is simple giving information on one of two questions. First is how the is is formed. This type of question produce a lot of short essay samples. The second question is why the thing happens. Now we have an example of explanation text about how.
How Roman Roads were Built
The system of roads for mobility has been begun early decades. It was started since the Roman Empire conquered the world. The roads in Roman era were known as the best construction.
The Romans built roads are for the purpose of mobility, especially for the army. Having the best road, the army could march from one place to another. They built the roads as straight as possible, so that the army could take the shortest route.
It is interesting to know how the roads were built, which some of them are still in use today. First, the Romans builders would clear the ground of rocks and trees. Then they dug a trench where the road was to go and filled it with big stones. Next, they put in big stones, pebbles, cement and sand which they packed down to make a firm base. After that, they added another layer of cement mixed with broken tiles. On top of that rough construction, then they put paving stones to make the flat surface. These stones were cut so that they fitted together tightly. As the finishing touch, kerb stones were put at each sides of the road to hold in the paving stones. It was also used to make a channel for the water to run away.

Note on Generic Structure
Now we are going to see the generic structure of the explanation sample above.
Every explanation text will be started with General Statement of the text. It is purposely to introduce the topic of the text. From the example above, we point that the Roman road architect is the main discussion, just seeing from the first sentences.
After stating the introduction, text in explanation type will be followed with a Sequenced Explanation. It is the blueprint of the general statement which needs to be explained in detail on how or why something is formed. In the last paragraph, we clearly get the explanation on how formerly the Roman Empire Roads were built step by step.
