现代英语中出现了许多不用if,unless,as long as等连接词语表示条件的特殊情况。本文就其他表示条件的特殊表达方式归纳如下，希望对同学们有所帮助。
一、并列结构
1.祈使句+and简单句。祈使句具有条件的意味。这个句型表示肯定条件，and表示自然的结果。例：
Push the door hard,and it will open.(=If you push the door hard,it will open.)
使劲推门，门就会打开。
Finish your work and I’ll give you some ice cream.(=If you finish your work,I’ll give you some ice cream.)
你干完活，我就给你些冰琪淋。
Work hard and (=If you work hard) you will pass your examination.
如果你努力学习，就会考试及格。
Go and I won’t call the police.
走开，否则我就报警了。
2.祈使句+or简单句。此句型中的祈使句表示否定条件，or表示结果。例：
Write it down,or you’ll forget it.(=If you don’t write it down,you’ll forget it.)
写下来，否则你会忘记的。
Work hard,or you won’t be able to pass your examination.
努力学习，否则你无法通过考试。
Go,or I’ll call the police.
走开，否则我就报警了。
Don’t eat so much,or you’ll be sorry.
不要吃那么多，否则你会后悔的。
3.名词词组+and简单句。这种句型不但简洁，而且条件意味十分突出。例：
One more effort and you’ll succeed.(=If you make one more offort,you’ll succeed.)
再努力一把，你就会成功。
Another half hour and all doors would be locked.(=If another half hour should pass,all doors would be locked.)
再过半个钟头，所有的门都要上锁了。
二、动词say,suppose引导从句
这类句型多用于疑问句中，同引导条件状语从句的用法一样。
1.Let’s say that...
Let’s say that your plan fails,then what do we do.
假使你的计划失败，那我们怎么办？
2.say(=If,Let’s say)
Say you have had an accident,who would look after you?
如果你遭受意外，谁会来照料你？
3.suppose（=supposing)
Suppose (that) the news is true,what then?
假定这消息是真的，又该怎么办？
Suppose you had a million pounds,how would you spend it?
假定你有一百万英镑，你会怎么花？
Suppose it rains,what shall we do?
万一下雨，我们该怎么办？
三、非谓语形式表示条件
1.不定式表示条件包括两种：表示真实条件和虚拟条件（含蓄条件）。
It would be a mistake not to help him.(=It would be a mistake if we didn’t help him.)
不帮助他将是一个错误。
To hear him speak English you would take him for an Englishman.
如果听他说英语，你就会把他当成英国人。
To listen to him,you should think that no problem whatever existed.
如果听他说话，你就会认为什么问题也没有。
2.分词短语（或含分词短语的独立主格结构）表示条件。
Working hard,you will succeed.
努力拼搏，你就会成功。
Turning to the left,you will find the path leading to the site.
如果你朝左拐，你会发现这条路通往工地。
I’ll come tomorrow,weather permitting.
如果天气许可的话，我明天就来。
United,we stand;divided,we fall.(=If we are united,we stand ;if we are divided,we fall.)
团结则存，分裂则亡。
Heated,water changes into steam.(=If water is heated,it changes into steam.)
如果加热，水就会变成蒸汽。
All things considered,his paper is of greater value than yours.
如果考虑到各方面，他的论文比你的更有价值。
四、seeing(that),provided/providing(that),saving(that),considering(that),supposing(that),granting/granted that,given(that)等用作连词，引导条件状语从句。
Supposing (that) it rains,can we play the match indoors?
如果下雨，我们能在室内比赛吗？
You can borrow my bike provided/providing you bring it back.
你可以借我的自行车，只要你送回来。
I’ll give you the day off on condition that you work on Saturday morning.
