(Note, some but not all, English teachers, including the ones I had, advocate not mixing numeric representation 50,000 with character representation: fifty thousand. In the following, I am using only character representation.)
During the last decade, there is an increasing number of people choosing to travel abroad. From the table we can see that only ten thousand people travel abroad in 1995, and, at the turn of the century, the number just climbed to forty thousand. However, lat year, 2005, over one hundred and twenty thousand people had an oversea trip.
In my opinion, this trend exists thanks to three reasons. First, with our national economy growing, the living standard for all Chinese has gained a huge improvemnt. Chinese citizens now have enough money to pursue their dreams, and travelling abroad is one of them. Second, people in the Middle Kingdom have much more spare time than before. They have two long special vacations, for instance, National Day and Labor Day, each of which is one week’s long. Last but not least, folks are eager to broaden their views by going to a foreign country and exchanging (going...exchanging) different cultures.
The effect of this phenomenon is positive. Our economy can be spurred on by this way. People can communicate with others of different cultures and make full use of the advantage of those cultures.
