英語的主語有哪些10個

名詞作主語
例：The villagers didn't realize how serious the pollution was until the fish in the river died.

S（subject主語）+ V（verb謂語動詞） +O（object賓語）. 主系表結構 :S（subject主語）+V（verb謂語動詞，也稱爲系動詞，就是所說的“系”）
倒裝：Not until the fish in the river died did the villagers realize how serious the pollution was.
注意：倒裝在主句，從句不倒裝 /did 和not 提前，只剩動詞原形
強調：It was not until the fish died in the river that the villagers realized how serious the pollution was.
如果強調的是主語或賓語且指人用who，其他一律用that。是that，而非其他/主句的順序（倒裝不強調，強調就不倒裝）
