动词不定式作主语
在正式的书面文体中，如果是不定式作句子的主语，那么 要将不定式后置，而用引导词it 来取代它的主语位置。It 在句中没有任何意义，是句子的形式主语；真正的逻辑主 语还是不定式。 另外，如果要说明不定式短语的逻辑主语是谁，可在不定 式前面加for sb.短语； 在某些形容人的品质的形容词作表语时，则要用以of sb.短 语（这类形容词常见的有：kind , good , nice , wise , unwise , clever , silly , wrong , right , foolish , stupid , careless , considerate , rude , naughty , impolite）
