Chapter19 Grammar Focus不定詞練習

P233

不定詞依其在句中的功能，具有名詞形容詞及副詞的性質。例如：

To get up early is good for the health. (早起對健康有益)

To get up early在主詞位置，故有名詞的性質。

I want to go. (我得走了)

to go在受詞位置，故有名詞的性質。

I don’t know what to do.(我不知道該怎麼辦)

what to do處受詞位置，故有名詞的性質。（不定詞前when, where, how, what等疑問字。）

His dream is to travel around the world. (環遊世界是他的夢想)

to travel around the world處於補語的位置，故有名詞的性質。

I have nothing to do.我無事可做--閒著無事

to do修飾nothing， 因此有形容詞的性質。

I was glad to get a letter from you. (我很高興收到你的一封信)

to get a letter from you說明glad的原因，故有副詞的性質。

We left early to get there on time. (為了準時到達那裡我們提早離開)

to get there on time說明left early的目的，故有副詞的性質。

Q&A回覆內容

A1:sh3025

謝謝你幫我把不定詞（）起來

3. They are preparing 【to return （to their home country）】.

= > （副詞）修飾 return

◎第二個to是介係詞。

6. They are discussing how （to show their feelings of gratitude）.

= > 名詞

◎how也要放進（）裡

9. Chinese people sometimes give a hongbao （to show thanks）.

= > 形容詞修飾hongbao

◎（to show thanks）說明give a hongbao的原因，故為副詞。

10. Our problem is 【how to say thanks （to our teachers）】.

= > （名詞）

◎第二個to是介係詞。

Q2:

有關 to 有不定詞和介係詞的二種用法可以再說明嗎？

A2:

sh3025

to當不定詞：to＋原形v

to當介係詞：to＋名詞（動名詞）

以3. They are preparing 【to return （to their home country）】.為例

to return＝ to＋原形v，就是不定詞

to their home country＝to＋（形容詞＋）名詞，就是介係詞
