談?wù)勚鷦釉~(AUXILIARY VERBS)
助動詞也是動詞的一種，它用以表示：可能、應(yīng)該、愿望、必須……通常放在動詞（verb)或形容詞（adjective)之前。它也時常令初學(xué)者感到混淆。
一、shall 和 will
1.1 助動詞shall/will 的最常用法，就是表示后面的動詞屬于未來式(future tense):
第一人稱(I、we)用shall:
I shall go tomorrow.
We shall go tomorrow.
第二人稱(thou、you)及第三人稱(he、she、it、they)都用will:
He will go tomorrow.
She will go tomorrow.
They will go tomorrow.
1.2 如果shall或will并不是用來表示后面的動詞是未來式的，那么shall將用在第二及三人稱，這時就有"決定、命令、答應(yīng)"等意思：
You shall obey me.(你要服從我。）
He shall leave the house instantly.（他決定馬上離開家。）
You shall have my book.（說這話的人答應(yīng)把書給對方。）
同樣的，will用在第一人稱時，就有"決定、答應(yīng)、情愿"等意思：
I will speak, in spite of you.(不管你怎樣，我決定說。）
I will never forsake you.(我永遠(yuǎn)不會舍棄你。）
這回就談到這里。下回談should和would。

1、表示"必須"：
You must listen to him. 你必須聽他的話。
(注意：如果要說"你不必聽他的話。" 可不能說 "You must not liston to him。"而要說：

七、need和dare
1、need：
當(dāng)用作助動詞時，它的特征是：第三人稱、現(xiàn)在式（Present tense)、在疑問句或否定句里指過去、后面的infinitive沒有"to":
Need he go yesterday? (注意：句子指過去，但need為現(xiàn)在式，he go 不作 hegoes)
He need not go yesterday.
He need not have any help from us yesterday.
2、dare：
和need一樣，dare 和 need 除了用作普通的動詞外，也可用作助動詞。它的句子特征是：否定或有否定意味、dare后面的infinitive沒有"to"、用dare不用dares、有時指過去的事：
He dare not go.
He dare not do anything.
He dare not take such a step.
No-one dare go.
Dare he go?
"I dare say" 這種說法有"我以為"、"大概"、"在我看來"、"或者"的意思：
