如果否则英文

否则的英文单词otherwiseor elseif not

1.当if…not…引导非真实条件分句时，一般不可改用unless。 例如：If she had not had an alarm clock,she would have missedthe train.（事实：她有闹钟。）如果把上述例句中的if…not…换成unless，意义就相反了。（误）Unless she had had an alarm clock, she would havemissed the train.（事实：她没有闹钟）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。例如：She won't lose weight if she doesn't keep a diet and ifshe does not take exercise every day.3.unless引导的分句可用否定结构，而if…not …引导的分句不可再否定。例如：Don't ask me to explain unless you really don't understand.The directors have a meeting every Friday,unless there is nothing to discuss.以上两例句中的unless不可换成if…not…。
