2010
The column chart on mobile-phone subscriptions above shows a striking contrast between those developing countries and developed countries in the past decade. Since 2004, people in growing numbers in developing countries use mobile phone, while those in developed countries far lag behind. By 2008, there are 4 billion mobile-phone users in developing countries, which is 3 times more than that in developed countries.
Two reasons may contribute to the contrast above. On the one hand, with the rapid increase in economy of developing countries, the telecommunication industry there surges to meet the demand of globalization. Therefore, mobile phone users grows at an incredible speed. On the other hand, developed countries had reached a state of prosperity in economy, and created less rooms for further developments in mobile subscriptions. Maybe that is the reason why the number mobile phone users in the developed countries keep even over the last decade.
To sum up, mobile phone is convenient for interpersonal communications, and gradually become the indispensable tools in people's life. When enjoying the convenience of cell phones, we should
also keep an eye on the negative effects it mi ght bring to our environment. Only in this way can people in developing countries see a sustainable grow in telecommunications.
Dear Jack:
I would like to convey my heartfelt thanks to you for your warm reception when I participated in the exchange program in your country.
Your generous help made it possible for me to have a very pleasant stay and a chance to know American culture better. Besides, I think it is a great honor for me to make friends with you and I will cherish the goodwill you showed to me wherever I go. I do hope that you can visit China someday, so that I could have the opportunity to repay your kindness and refresh our friendship.
I feel obliged to thank you again.
Sincerely Yours,
Zhang Wei
