補上一篇的：本書把不定式也歸於‘語氣（mood）’類了

There are four simple moods, the Infinitive, the Indicative, the Imperative and the Subjunctive.

語氣（Mood）是動詞的一種變化形式。它用來表示說話人對某一行為和事物所持的態度和看法。英語中有三種語氣：陳述語氣（Indicative Mood）、祈使語氣（Imperative Mood）和虛擬語氣（Subjunctive Mood）。          陳述語氣：用以敘述存在的動作和狀態或詢問某件事情。        --Education is the best way for a nation to invest in the future.        --What wonderful weather it is!         --Have you finished reading the book?        祈使語氣：用以表達請求、希望、命令、勸告、禁止等意思。        --Let’s not waste time.        --Don’t forget to close the window.        --Please tighten your safety belt.          虛擬語氣：用於表示動作或狀態不是客觀存在的事實，而是說話人的主觀願望、請求、建議、假設     或推測。        --If there were no gravity, we should not be able to walk.        --It is important that the plan (should) be worked out today.        --If only you would listen to reason!（你如聽從勸告就好了!）

 

Infinitive mood  就是 不定式
