不是的。英语的主语不仅仅局限于I、you、she、he、it、we、you、they这些词。英语中的主语可以是名词、代词、数词、不定式、动名词、名词化的形容词、名词性从句等。以下是一些例子:
1. 名词:The cat is sleeping.
2. 代词:You are right.
3. 数词:Three students are absent today.
4. 不定式:To learn English is my dream.
5. 动名词:Swimming is a good exercise.
6. 名词化的形容词:The beautiful garden is full of flowers.
7. 名词性从句:What he said was interesting.
英语的主语非常多样,可以根据句子结构、语境等因素进行选择。
