1.不定式(短語)??捎米髦髡Z,如:
To see is to believe.
眼見為實。
To act like that is foolish.
這樣做是愚蠢的。
2.但在很多情況下,我們都把不定式往后移,前面用先行詞it作形式上的主語,這樣句子結構會顯得更平穩(wěn)。這時謂語可以是:
1)be+形容詞:
It isn't right to talk like that.
這樣說是不對的。
It's difficult to master English.
精通英語是不容易的。
2)be+形容詞+for引起的短語:
It's hard for me to answer.
我很難回答。
It isn't right for us to stop half way.
我們半途而廢是不對的。
3)be+形容詞+of引起的短語:
It's kind of you to think so much of us.
難得你為我們這樣著想。(=you are kind to...)
It's good of you to come to meet us.
非常感謝你們來接我們。
4)be+名詞:
It's our duty to do that.
這樣做是我們的職責。
It's a mistake not to help them.
不幫助他們是錯誤的。
5)其他形式的謂語:
How long does it take to get there?
到那里需要多少時間?
How much did it cost you to send the package?
寄這包裹花了多少錢?
