The unless-clause can cme first r after the main clause.Unless yu try yur best, yu will nt realize yur dream.Yu will be late unless yu leave right nw.

if、unless 引导的条件状语从句
e.g. Please call me if he is at hme.假如他在家的话, 请给我打电话。
考题1：_______ we always wait fr anther day, fruitlessly ur life will pass away.A. Until B. If C. Althugh D. Whether
【分析】分析句意可知, 逗号前“我们总是等待另一天”是逗号后“我们的生命将徒劳地逝去”发生的条件, 故空格处用if 引导条件状语从句。
[重点] 时态如果主句是一般将来时, 从句一般用一般现在时。e.g. I wn’t g there with yu if it rains tmrrw.如果明天下雨的话, 我就不和你一起去那儿了。
如果主句谓语含有must、may、can 等情态动词或主句是祈使句, 从句也用一般现在时。e.g. If it is fine tmrrw, we can g and fly the kite.如果明天天气好, 我们可以去放风筝。Put yur hand up if yu need mre paper.若有人还要纸, 请举手。
考题2：[北京] Dn’t lse heart. If yu keep wrking hard, yu _______ sme day.A. will succeed B. succeedC. succeeded D. have succeeded
e.g. Please tell me if he cmes back.= If he cmes back, please tell me.如果他回来了, 请告诉我一声。
请比较:(1) We will g ut if it is fine tmrrw.(2) I dn’t knw if the train has arrived.句(1) 中if 引导的是状语从句。这个从句表示“条件”, 整个句子的意思是“如果明天天气好, 我们就出去”。句(2) 中if 引导的是宾语从句, 充当谓语动词knw 的宾语, 整个句子的意思是“我不知道火车是否到了”。
考题3：[百色] I dn’t knw if it ______ tmrrw, but if it ______, I’ll stay at hme.A. will rain; rains B. will rain; will rainC. rains; will rain D. rains; rains
【分析】本题用语法判定法。考查动词时态。由句意“我不知道明天是否会下雨, 但如果下雨, 我会待在家里。”可知, 第一个空格处所在句中if 意为“是否”, 引导宾语从句, 主句为一般现在时, 由tmrrw 可知, 从句应用一般将来时, 结构为will+ 动词原形；第二个空格所在句中if 意为“如果”, 引导条件状语从句, 主句为一般将来时, 从句用一般现在时, 故选A。
拓展：条件状语从句和主句还有一个共同的伙伴, 有时它可以替代从句和主句, 它就是“祈使句+and/r+ 陈述句 ”。其中and 表示句意顺承； r 则表示转折, 意为“否则”。e.g. If yu wrk harder, yu’ll pass the exam.= Wrk harder, and yu’ll pass the exam. 如果你再努力些, 你就会通过考试。
考题4：[上海] Keep wrking hard, and yu will achieve success. (保持句意不变) _______ _______ keep wrking hard, yu will achieve success.
If yu
e.g. Yu’ll fail in French unless yu wrk harder.=If yu dn’t wrk harder, yu’ll fail in French. 你要是不再加把劲儿, 法语就考不及格了。
e.g. He cannt see clearly unless he wears glasses.他不戴眼镜就看不清楚。注意: 在含unless 或if 引导的条件状语从句的复合句中, 主句用一般将来时, 从句用一般现在时代替一般将来时。即所谓的“主将从现”。
考题5：[盘锦] The little by wn’t g t sleep unless his mm _____ him a stry.A. tells B. tldC. is telling D. will tell
【分析】unless 引导的条件状语从句遵循“主将从现”的原则。故选A。
拓展：(1) “祈使句( 肯定式) +r+ 陈述句”与“unless 条件状语从句+ 主句”有时可以相互转换。e.g. Put n yur raincat, r yu’ll get wet.=Unless yu put n yur raincat, yu’ll get wet.=If yu dn’t put n yur raincat, yu’ll get wet.穿上你的雨衣, 否则你会淋湿的。
考题6：[启东二模] If he desn’t study hard, he wn’t make prgress. (保持句意基本不变) He wn’t make prgress _________ he _________ hard.
unless studies
(2) unless 引导出补充前言的句子, 即对刚说过的话进行补充。e.g. Let’s play chess—unless yu really have smething urgent t d.咱们下国际象棋吧—除非你真有急事要办。
(3) unless 在以下情况不能与替换。①当某种条件所引起的结果是一种情绪或想法时, 不能使用unless, 只能用。e.g. I will be angry if I am nt invited t the party.如果我不被邀请参加这个聚会的话, 我将会生气。② 可以引导一个虚拟条件句, unless 一般不引导虚拟条件句。e.g. If she weren’t s silly, she wuld understand it.如果她不那么傻, 她就会明白它的。
