動名詞當主詞

一、基本句型 動名詞當主詞 動名詞 : 動詞 + -ing Eating breakfast is important. Playing computer games fun. 1.動名詞作主詞時，受詞即使為複數，仍視為單一動作或事件，須視為單數，其後須接單數動詞。 例一 : Cooking noodles is easy. 例二 : Reading comic books is fun. 2.兩個動名詞當主詞時，其後接複數動詞。 例一 : Playing baseball and going to the movies are fun for me.

虛主詞 It 的用法

一、核心概念 虛主詞 it 不定詞片語當主詞時，可以用虛主詞 it 當句子的主詞代替不定詞片語。 例句 :It is easy to ride a bike. 例句中，真正的主詞是 to ride a bike ，為避免不定詞片語放在主詞位置有頭重腳輕的狀況，以虛主詞代 替不定詞片語。

二、基本句型 虛主詞 it It + be 動詞 + 形容詞 + 不定詞片語. It is terrible to be sick. good take a family trip. 虛主詞 it 的否定句用法，直接在 Be動詞之後加上 not 即可。 例一 : It is not easy to save money. (存錢不容易)。

虛主詞 it 虛主詞 it 當句子主詞也可加「for + 人 (受格)」，表示「對…人而言」。其句型為： It + beV + 形容詞+ for + 人(受格) + 不定詞片語. it 例一 : It is good for him to exercise every day. (每天去運動對他是好的。) 例二 : It is difficult for him to get up early. (對他而言要早起很困難。) 但如果遇到形容詞 kind、nice、sweet、smart時，則用「of + 人(受格)」。 例一 : It is kind of you to help us. (幫助我們，你們真好。)
