名詞作主語

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

直到河里的魚死了，村民們才意識到污染的嚴重性

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，也稱為系動詞，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)

人稱代詞(主格)，名詞性代詞，指示代詞，不定代詞，such(----樣的人、物)，it(時間，天氣，距離等)

at midnight /in the(泛指)middle of the night

例：It is 9 o'clock when I went home.

我回家的時候已經九點了

一般句：It was nine when I got home.

強調句：It was at nine that I got home.

原形：I got home at nine.

注意：作主語在句首/it作主語構成(常用 v-ing，不常用只有 use，good)
