動詞不定式（短語）作主語時，一般表示具體的、個別的、一次性的或具有將來意味的動作。若動詞不定式（短語）太長，常用it作形式主語而將不定式后置?！咀⒁狻?/p>

當(dāng)動詞不定式（短語）作主語的句子中又有一個動詞不定式（短語）作表語時，不能用it作形式主語。如：Toseeistobelieve.

眼見為實。（不可改為Itistobelievetosee.）動詞不定式（短語）作主語單個動詞不定式（短語）作主語，謂語用單數(shù)。ToimproveEnglishisthemosturgentthingformenow.兩個或兩個以上的動詞不定式（短語）作主語，若語義一致或基本一致，或動詞不定式（短語）作為一個整體，謂語用單數(shù)。Toloveandtobelovedissweettous.兩個或兩個以上的動詞不定式（短語）作主語，若語義不一致，謂語用復(fù)數(shù)。

動詞不定式（短語）和動名詞（短語）都可在句中作主語，動詞不定式（短語）作主語時，在很多情況下都可用動名詞（短語）替代。但是，如果作主語的動詞不定式（短語）是固定說法，或表示較強烈的對比，或表示具體的、特定的情況等，通常不用動名詞（短語）替代。如：

Toerrishuman,andnobodylikesaperfectperson.（不說Erringishuman.)

是人都會犯錯，而且誰也不喜歡完人。

Tofinishthisjobinonedayisimpossible.
