用if造十个句子

用If so造10个句子~

1．unless不能与if'"not换用的情况 unless在意义上相当于if...not，因此在有些场合中unless与if...not可互换使用。如： Unless I am mistaken．I’ve seen that man before．=lf I am not mistaken。I’ve seen that man before．如果我没搞错，我以前见过那个人。 Unless the strike has been called off，there will be no trains tomorrow．=lf the strike has not been called off。there will be no trains tomorrow．除非罢工结束了，明天才会有火车。 但在有些情况下，二者不可互换使用。如： (1)当unless引导非真实条件句时，一般不可改用if...not。如： They couldn’t afford to live in such an expensive apartment unless they were rich．除非他们很富有，否则就住不起这么昂贵的公寓。 They couldn’t have arrived at the site instantly unless the police had had a helicopter．除非警方有直升机，不然他们就不会即刻赶到事发地点。 以上两例中，unless从句均表示与事实相反的情况。如果把unless换成if...not(…if they were not rick,…if the police had not had a helicopter)就与原句意义完全相反了。 (2)if...not引导的条件分句可以重叠使用，unless则不可，因为unless表示唯一条件，不能用and连接两个unless引导的从句。如： She won’t lose weight if she does not keep a diet and if she does not take exercise every day．=She won’t lose weight unless she keeps a diet and takes exercise every day．除非她坚持节食、每天锻炼，否则是不能减肥的。 (3)unless引导的条件句可用否定结构，而if...not引导的条件句不可再加以否定，因为两个not不能重叠使用，因此在unless引导的否定条件旬中，不能用if...not替代unless。如： Don't ask me to explain unless you really don’t understand．除非你真不懂，不然别让我解释。 The directors have a meeting every Friday．unless there is nothing to discuss．董事会每周五开会，无事讨论除外。 You will get a good grade in the course unless you don’t do your homework．如果你(不是不)做作业的话，你就会有好的学业成绩。 (4)当if引导名词性从句时，unless不可以代替if...not，因为if=whether(“是否”)。如： It is unimportant if he will not attend the graduation ceremony．他是否参加毕业典礼无关紧要。 I doubts if he has not made a contribution to the environment．我怀疑他是不是没有为环保做过贡献。 (5)当unless作介词(“除……以外”，“除非”)时，if...not不能与其互换使用。如： Nothing will come out of it．unless(=except)disaster．这件事除了引起灾祸之外，不会有什么结果。 Nothing．unless a miracle，can save him．除非出现奇迹，否则他无法得救。 2．unless从句中成分的省略 unless从句的主语与主句的主语相同时，unless从句中的主语和谓语(或一部分)有时可省略。如： Unless(he is)in uniform。he doesn’t look like a policeman．如果不穿上制服，他看起来就不像警察。 Unless(I am)compelled t0 stay in by bad weather，I go for a walk every day．若非天气不好被迫呆在家里，我每天都出去散步。 Don't leave the building unless(you are)instructed to do so．没有得到通知，不要离开大楼。 The virus is capable of destroying an information stored in a computer unless(it is)detected and eradicated．病毒如不查出并清楚掉，会把存储在计算机里的资料全部毁掉。 3．unless从句的时态 主句是一般将来时态、祈使句或谓语中含有情态动词或主句是一般现在时，unless引导的真实条件句用一般现在时；如果强调从句动作发生在主句动作之前，从旬可用现在完成时。 Don't touch the instruments unless the teacher allows you．没有老师的允许，不要乱动仪器。 Unless you know a word，you may consult a dictionary．如果你不认识哪个词，你可以查词典。 但主句是过去将来时或过去时，unless引导的真实条件句常用一般过去时。如： The disease prevented him from remembering things unless he was reminded by another．这种病使他记不住事，只能靠别人提醒。 4．“祈使句(肯定式)+or／otherwise+陈述句”与“unless条件句+主句”间的转换 “祈使旬(肯定式)+or(else)／otherwise+陈述句”与“unless条件句+主句”间有时可以相互转换。如： Put on your raincoat or you’ll get soaked．=Unless you put On your raincoat， you’ll get soaked．If you don’t put on your raincoat，you’ll get soaked．把雨衣穿上，否则你就会全身湿透的。 Store the meat in the fridge，otherwise it will go the fridge，otherwise it will go off．If you don't store the meat in the fridge，it will go off．把肉放在冰箱里，不然就会坏掉。

If it doesn't rain tomorrow,we will have a picnic
