情態(tài)動(dòng)詞will與would的用法

1. 表示意愿

will 表示現(xiàn)在的意愿，would表示過去的意愿。如：

I will pay you at the rate you ask. 我愿意照你要求的價(jià)錢付款。

Go where you will. 你愿到哪里就到哪里。

He wouldn’t help me yesterday. 他昨天不愿幫助我。

She asked if I would go with them. 她問我是否愿同他們一起去。

【注】(1) 表示“意愿”的 will 有時(shí)可用于條件句中。如：

If you will allow me, I will see you home. 如果你同意，我可以送你回家。

(2) would也可表示現(xiàn)在的意愿，語氣較委婉。如：

I’d go there with you. 我愿同你去那兒。

I wouldn’t go. 我不會(huì)去。

2. 表示征求意見或提出請(qǐng)求

主要用于第二人稱的疑問句中，will和would均可用，would此時(shí)并不表過去，而表示委婉語氣。如：

Won’t you take off your coat? 你要不要把大衣脫掉?

Will [would] you please post the letter for me? 請(qǐng)幫我寄了這封信好嗎?

Would Sunday night suit you? 星期天晚上適合你嗎? (from www.網(wǎng)址未加載)

【注】(1) 有時(shí)為使語氣委婉，可用否定式?？偟恼f來，用would比用will委婉，用won’t和wouldn’t比單獨(dú)用will和would要委婉。

(2) would有時(shí)用于提出想法，通常與like, love, hate, prefer, be glad, be happy等連用，若用于第一人稱有時(shí)也可將would換成should。如：

I’d like [love] to have a look at it. 我想看看它。

I would prefer not to go out today. 我今天不想出去。
