摘要：He'd better find it quickly, or else (= or I will punish him in some way)! (他最好快点找到，否则!)[剑桥高级学者辞典]【例句4】Hand over the money, or els
1. 用作警告或威胁
or else可以用来警告或威胁，效果是“否则的话，哼哼！”如
【例句1】Just shut up, or else! （闭嘴，否则！ ） [牛津高级学者辞典]
【例句2】Behave, or else! (规矩点，否则！)[柯林斯高级学者辞典]
【例句3】He'd better find it quickly, or else (= or I will punish him in some way)! (他最好快点找到，否则!)[剑桥高级学者辞典]【例句4】Hand over the money, or else! （把钱交出来，否则！）[朗文当代英语词典]
【例句5】He told us to put it right, or else. (他告诉我们要改正，否则。) [柯林斯高级学者辞典]
这是口语用法(else的语气也很重，所以多加！)，不用特别讲究主谓宾要全乎。
2. 正式表达“不想看到不希望的结果”
对正式的用语，句子还是要全乎的，如
【例句6】Hurry up or else we'll miss the train. （快点，否则我们会错过火车的。）[朗文当代英语词典]
【例句7】Hurry up or else you'll be late. （快点，否则你会迟到的。）[牛津高级学者辞典]
【例句8】We must be there by six, or else we'll miss the beginning. （我们必须在六点前到那里，否则我们会错过开始的。）[剑桥高级学者辞典]
【例句9】This time we really need to succeed or else people will start giving us funny looks. (这次我们真的需要成功，否则人们会开始给我们滑稽的眼神。) [柯林斯高级学者辞典]
【例句10】Make sure you are strapped in very well, or else you will fall out. （确保你系好安全带，否则你会掉下来的。） [柯林斯高级学者辞典]
因为说话人的认知是不喜欢的结果确实会出现，所以用将来时，即助动词will。
3. 排除不可能情形
or else也用于排除别的情形，此时被排除的用虚拟式，显表达说话人不认可。如，
【例句11】He must be a good plumber, or else he wouldn't be so busy. （他一定是个好水管工，否则他就不会这么忙了。）[柯林斯高级学者辞典]
【例句12】Clearly no lessons have been learnt or else the problem would have been solved.（显然，没有吸取任何教训，否则问题就会得到解决。） [柯林斯高级学者辞典]
【例句13】They can't be coming or else they'd have called. （他们不可能来，否则他们会打电话的。）[牛津高级学者辞典]
4. 表达平行选项
or else也可表达“与前者平行的其它选项，两者都有可能”(在1,2,3情形中，后句是对前句的推演)，如
【例句14】The salesman will reduce the price or else include free insurance. （推销员要么降价，要么提供免费保险。）[朗文当代英语词典]
【例句15】You are either a total genius or else you must be absolutely raving mad. （你要么是个天才，要么一定是疯了。）[柯林斯高级学者辞典]
【例句16】It's likely someone gave her a lift, or else that she took a taxi. （很可能有人载她一程，或者她坐了出租车。） [柯林斯高级学者辞典]
【例句17】He either forgot or else decided not to come. （他要么忘了，要么决定不来。）[牛津高级学者辞典]
【例句18】She's either really talkative and you can't shut her up or else she's silent.（她要么非常健谈，你不能让她闭嘴，要么她很沉默。）[剑桥高级学者辞典]
