About a century ago more people would not have appreciated the study of a foreign language
as they do today. Gone are those days when patriotism towards one's own language was a major obstacle to learning foreign languages, a time when most nations were trying to throw their alien rulers out of their countries in their freedom struggles. Gone are those days when people were proud of their mother or father tongues and considered that their languages alone will suffice the need to survive. Language skills today have become as important as other business and career skills like IT, vocational or professional skills. Thus learning a foreign language today has become essential for an individual whether it is for careers, growing a business, or even to make an impression.

All that one needs to possess these days is a drive to learn a foreign language and there are all kinds of institutes and courses that teach various foreign languages like French, German, Spanish, and Japanese. Today's world economy has bridged the barriers of race, sex, color and religion and the world has become a smaller place. Today's businesses also demand language skills to expand and grow in other countries. Tens and hundreds of businesses world wide are expanding and growing their businesses by promoting them in countries other than their countries of origin. The tremendous growth of the Internet has further increased the demand for language skills. In Canada an official rule also says that all commercial establishments must have their websites created both in English and French, the official languages of the country.
Language can also ease race and border barriers. You are more welcome in an alien nation if you know the language of the people there and can converse in their tongue. People in these countries immediately respect you and think you care about their culture as much as they do because in any culture language is the key identity.
One of the reasons for not studying a foreign language in the past is______.
A．it was too difficult
B．it was not allowed
C．it was taught by foreign rulers
D．it was seen as disloyalty
