·PG-13级：
(PARENTS STRONGLY CAUTIONED Some material may be inappropriate for children under 1 3. )普通级，但不适于13岁以下儿童.特别辅导级，13岁以下儿童尤其要有父母陪同观看，一些内容对儿童很不适宜——该级别的电影没有粗野的持续暴力镜头，一般没有裸体镜头，有时回游吸毒镜头和脏话；
·R级：(RESTRICTED Under 17 requires accompanying parent or adult guardian.)限制级，17岁以下必须由父母或者监护陪伴才能观看.限制级，17岁以下观众要求有父母或承认陪同观看——该级别的影片包含成人内容，里面有较多的性爱、暴力、吸毒等场面和脏话；

·M，X OR P：这一级中的电影基本上不适合在大院线里公映，都属于限制类的。
The rating system is a guide that helps you determine the movies content prior to viewing it. For a complete details on how it work, see Questions & Answers: Everything You Always Wanted To Know About The Movie Rating System.
What do the ratings symbols mean?
G:General Audience. All ages admitted. This signifies that the film rated contains nothing most parents will consider offensive for even their youngest children to see or hear. Nudity, sex scenes, and scenes of drug use are absent; violence is minimal; snippets of dialogue may go beyond polite conversation but do not go beyond common everyday expressions.
PG:Parental Guidance Suggested. Some material may not be suitable for children. This signifies that the film rated may contain some material parents might not like to expose to their young children - material that will clearly need to be examined or inquired about before children are allowed to attend the film. Explicit sex scenes and scenes of drug use are absent; nudity, if present, is seen only briefly, horror and violence do not exceed moderate levels.
PG-13:Parents Strongly Cautioned. Some material may be inappropriate for children under 13. This signifies that the film rated may be inappropriate for
pre-teens. Parents should be especially careful about letting their younger children attend. Rough or persistent violence is absent; sexually-oriented nudity is generally absent; some scenes of drug use may be seen; one use of the harsher sexually derived words may be heard.
R:Restricted-Under 17 requires accompanying parent or adult guardian (age varies in some locations). This signifies that the rating board has concluded that the film rated contains some adult material. Parents are urged to learn more about the film before taking their children to see it. An R may be assigned due to, among other things, a film's use of language, theme, violence, sex or its portrayal of drug use.
NC-17:No One 17 and Under Admitted. This signifies that the rating board believes that most American parents would feel that the film is patently adult and that children age 17 and under should not be admitted to it. The film may contain explicit sex scenes, an accumulation of sexually-oriented language, or scenes of excessive violence. The NC-17 designation does not, however, signify that the rated film is obscene or pornographic.。
