5.How the world will be without Lenovo?

Answer:

1. It's a bit hard to translate the Chinese slogan into English because there are some English words which can't show the pun or the deeper meaning of Chinese words. For example, the last Chinese slogan for Lenovo. It uses a pun of the Chinese word 聯想 which can mean Lenovo as well as imgination. I try my best to translate it into a similar meaning without changing the words so much. What's more, Chinese slogans use more complicated but beautiful words, meanwhile, English slogans prefer simpler and vivider words. So Chinese slogans focus on the whole meaning, I have to change it into a complete sentence with injunctions in English.

2. I did some research on Google and Bing about the background information of those companies because it can help me know more about the products in the advertisements.
