虛主詞 it 的句型會因後面接著的是2個動詞(片語)而改將 it 改成 they 嗎?

It is good for you to study.(O)

It is (They are? ) good for you to study and exercise. (?)

Studying and exercising are both good for you. =They are both good for you. (?)

已更新項目:

若是改成~ Studying OR exercising ____ good for you. 是改用 is 嗎?

    虛主詞只能用it(不可用they),它只有文法功能,但同一句裡還有真正的主詞(delayed subject:延遲的主詞):真正的主詞可能是一個單字、一個片語、或一個子句。

    It is good for you to study. = To study is good for you.

    It is good for you to study and exercise. = To study and exercise is good for you.(如果你視不定詞to study and exercise是一體的,不可分割,即缺一不可,則用單數動詞的is); 但如果你將讀書和運動視為兩件事時,則可用are: To study and exercise are good for you.

    用虛主詞的寫法會比直接用不定詞較自然,因為英文有尾重的習慣(end-weight),通常把「比較重要的資訊」或是「比較長的文字」放在句尾。

    Studying and exercising are both good for you.按句意,studying和exercising 是兩個項目,所以用了both:兩者)

    They are both good for you.這裡的they是代名詞,代表前一句裡的兩個動名詞(studying和exercising),是句子真正的主詞,不是虛主詞。

    Studying or exercising is good for you.因為or表示「擇一」,所以這句的動詞跟or後面的名詞在數上取得一致:單數。
