语篇语法填空
Let me start by asking a question: what's the (one) thing you notice about a film？(actual), the film you see on the screen is the product of a huge amount of hard work, most of which takes place behind scenes.(begin) with, I'd like to draw your attention to a film's sound effects, which are often added after a scene (shoot) and might not be made in the way you would expect. Another aspect I attach great importance is visual special effects. As green doesn't match any natural hair or skin colour, actors can be easily separated from the background, scenes (require) CGI are frequently filmed in front of a green screen. Props, contributing to a film's success, require a lot of work. To make a film look much (real), great effort must be made to research, find and build objects. All in all， we see on the cinema screen is just the tip of the huge iceberg of filmmaking. Hopefully, next time you go to the cinema, you'll spare a thought for all those (talent) people.
