For example,
"去" (pronounced "Qú") is "going to the". "超市" (prounced "Chao Shi") is "supermarket" "去超市" (pronounced "Qú Chao Shi") is "going to the supermarket".

The size of a word does not correlate with it's concept - I still posit that some languages can transfer concepts faster than others, minus our baud rate.

For example, the characters comprising your example text starts like:
collect (收) [from] [all] soldiers (兵) under the sky (天下), gather (聚) at(?) (之) Xianyang (咸陽), melt (銷) and (以) become(?) (為) bell-stand (鍾鐻) metal (金) person (人) twelve (十二) ...
As you can see, the English "translation" is more like an annotated translation. E.g., the original doesn't say who did it, or what he collected from soldiers: we just inferred "weapon" because what else could be melted into statues?
Similarly, "standardized the axle width of carriages" is just: cart (車) same (同) axle width (軌). We're supposed to infer "standardized" because we are talking about the Emperor's deeds.

The old grammar and vocabulary coupled with the Chinese style of writing metaphorically with an abundant application of allusions and with the same Chinese characters having multiple unrelated meanings, makes Ancient Chinese texts very terse and notoriously difficult to understand even for the educated Chinese people.
