Section Ⅱ　GRAMMAR(1) it的用法 [教材示例] 分析下列教材中的句子，写出并体会它们的语法功能 1．Although highly regarded books do not always make good films，it is safe to say that great films may be made from not particularly good books. 2．Since a typical film is only around two hours long，it becomes a question for screenwriters to decide what is appropriate for the screen and what to leave out. 3．CGI(Computer Generated Image) technology has had a huge impact on the film industry. It allowed the previously unfilmable to become a reality. 4．One may think that it is the book writer who is in the best position to do film adaptations. 5．This can actually be a disadvantage because they may be too close to the material and find it difficult to adapt to a new form. 6．In this situation，it is clear that viewers will not be disappointed! 7．For me，anyway，it is always a bad idea to watch a film of a book you love.
