高中英語《在海里 Unit 3 Under the sea (part 4)）》(選修7)
非謂語動詞（V-ing形式）
V-ing 作動名詞時具有名詞的特征，因而在句中用作主語、表語、賓語、定語，有時它可以有自己的邏輯主語，也可以有時態和語態形式。
Laying eggs is the ant queen's full-time job.(主語）
Her job is teaching.(表語）
He is fond of playing football.(賓語）
developing countries     (定語）
working  people    （定語）
1.V-ing形式作主語表示抽象的經常性的意義。

早睡早起是一種好習慣。
Reading aloud is very important for us to learn English.
(1)v-ing 在It is no use/no good/fun/a waste of time/a good pleasure+doing 作主語，it為形式主語。

覆水難收

動名詞可具有時態意義
動名詞可以像動詞那樣表現時態意義。
一般式(doing)
完成式 （having done)
一般式表示動名詞的動作與謂語動詞的動作同時發生或在其后發生，或表示一般性動作，沒有時間概念。
完成式表示動名詞的動作在謂語動詞的動作之前發生。

其否定形式是：
