Channel 4前面用加冠词吗

你的问题是常见的.当专有名词是由名词加数词构成时,分为两种情况：名词+基数词,这种不加定冠词,名词和数词都得大写首字母.序数词+名词,必须在序数词前加定冠词.如 Unit 4 也可说成：the fourth unit；Class Three 也可说 the third class.还有Room 3301等等.
例子：
My family and I attended the 2010 Shanghai World Expo and I thought it was a great experience.
I was watching the news on Channel 4 last night when my cellphone rang
