In Britain, 12 on a film or trailer means the board has said only people aged 12 or over may see it. You will hear a 12, a 12 certificate, rated 12. The stories at this level can be scarier or ruder than a PG, but they are still meant for younger teenagers, not for adults-only films.

In Britain在英國，on a film or trailer電影或預告片上的 12 12，means the board has said意思是審查委員會說了，only people aged 12 or over只有滿十二歲的人，may see it才可以看。You will hear你會聽到 a 12、a 12 certificate 12 級證明、rated 12被列為 12 級。The stories at this level這個級別的故事，can be scarier or ruder than a PG可以比 PG 級更嚇人或更粗一些，but they are still meant for但它們仍然是給 younger teenagers較年輕的青少年看的，not for adults-only films不屬於成人限定的電影。

Though actually, British boards also use 12A: a child under 12 may go if an adult sits with them; a plain 12 (used more on home video) does not give that extra door.

Though actually不過實際上，British boards also use 12A英國的委員會還用 12A：a child under 12未滿十二歲的孩子，if an adult sits with them如果有大人陪著坐，may go就可以進場；a plain 12單純的 12 (used more on home video多用在家用影片上)，does not give that extra door就沒有這扇多出來的門。

This is not the American system: the US has PG-13, which is a cousin idea, not the same stamp. People say it in everyday talk about what to watch; it is a label, not a lesson in maths.

This is not the American system這不是美國的制度：the US has PG-13美國用的是 PG-13，which is a cousin idea那是表親般的概念，not the same stamp不是同一個章。in everyday talk about what to watch聊要看什麼的日常對話裡，People say it人們就這麼說；it is a label它是一個標籤，not a lesson in maths不是數學課。
