2016年職稱英語衛(wèi)生類考試句型學(xué)習(xí)：
To hear him talk...
結(jié)構(gòu)：To hear him talk，+主要子句
說明：此句型意為“聽某人談話(的口氣)…”。從形式上看，To hear him talk 似為不定式詞組，但實(shí)則為含蓄條件句(即不用 if 直接引導(dǎo))。To hear him talk 相當(dāng)于 If you could hear him talk。
To hear him talk,you'd think he was Prime Minister.
聽他談話(那口氣)，你會(huì)以為他是首相呢。
To hear you talk,I'd think you were Prime Minister.
聽你談話(那口氣)，我還以為你是首相呢。
Without ...S + V ...
結(jié)構(gòu)：Without …，+主要子句
說明：此句型意為“如果沒有…”，是導(dǎo)致主要子句結(jié)果發(fā)生的必要條件。Without ... 為含蓄假設(shè)條件句，此用法在口語表達(dá)中最為常見。without 意為“(如果)沒有…的話”。Without 既可以放在句首，也可以放在句尾，放在句首有強(qiáng)調(diào)作用。此外，如果主要子句用否定式，則和 without 構(gòu)成雙重否定，表示特別強(qiáng)調(diào) without 之后項(xiàng)為主要子句動(dòng)作發(fā)生之必備條件。
Without your help,I couldn't have done it.
(如果)沒有你的幫助，我是不會(huì)做成的。(=If you hadn't helped me)
She can't solve the problem without his help.如果)沒有他的幫助，她不可能解決這道題。
We can't live without air or water.(如果)沒有空氣或水，我們就無法生存。
Fish cannot live without water.(如果)沒有水，魚兒就無法生存。
What if/Say ...
結(jié)構(gòu)：What if/Say+子句，S+V ...
說明：此句型意為“假設(shè)…”。What if 和 Say 用來引導(dǎo)一個(gè)假設(shè)條件句，其義相當(dāng)于 Let us suppose(讓我們假設(shè))。
What if/Say he goes home before us and can't get in?What will he do then?
假設(shè)他在我們之前趕到家而又進(jìn)不去呢?那他怎么辦呢?
What if/Say you were to run out of money? What would you do?
假設(shè)你的錢用完了呢?你將怎么辦呢?
