填空题.After the year 1600, the British Empire began to spread English around the world. That process was given a huge boost in the 20th century through the business, technology and post-war reconstruction effects 21 of the US. Beyond this, there were a number of quite extraordinary ends in culture, science and the arts that were reinforced these developments. 22 Many of these were spontaneous, but others were high deliberate—the 23 work of the British Council, for example. Either way, English now stands challenged as the world's international language. 24 But the English language also has some inherent qualities that enabled this process even far. English is a "mongrel language" 25 that has always borrowed heavily from the other languages. This has allowed to grow quickly, flexibly, and efficiently. It has developed 26 spontaneously without an Academic Francaise to restrict it, for example, so 27 it has intended towards a simplification—from a more highly inflected 28 language towards becoming a less highly inflected one. Therefore, almost every educated person in the entire world knows 29 some English. Very few people anywhere would not consider it essential 30 part of an education in science, art, business, etc. There's a pretty clear dynamic at work here.
