One Day in 2016. At Home.
Possible version ne：
The box-office income of Chinese movies witnessed a constant increase from about 17 billion yuan in 2012 to over 40 billion in 2015. However, that increase slowed down in 2016.
The reasons behind this are various. The fast economic development before 2016 was probably the most powerful engine driving the constant growth in the box-office income. The application of new technologies and the wide appeal of movie stars could also account for the increase. However, China saw a decline in its economic growth rate last year. And the Internet increased options for movie lovers. Consequently, some viewers began to turn away from cinemas, leading to a slower growth.
China’s economy is expected to grow at a medium speed in the coming years, so an increase is possible in the investment in the movie industry and the number of quality movies. Therefore, its box-office income will probably enjoy a slight increase. (150 words)

As is indicated in the graph, the box-office income of Chinese films increased constantly from 2012 to 2015, but its growth, for one reason or another, slowed down in 2016.
The increase in the box-office income can be attributed to a number of factors. The quality of life has improved and watching films is regarded as a good means of entertainment. Besides, filming technology has advanced and more quality films are on offer. Moreover, the Internet plays an important part. On the Internet, people can seek information about their favorite stars and buy tickets at a discount as well, which is both time-saving and economical.
However, the film market may witness a slowdown in the near future. Cinemas have gradually given way to the rise of the Internet and cellphones, and the ticket price is on the increase. Therefore, the film industry should make greater efforts to attract more viewers. (150 words)
