ought与should的区别

Question

用法上的区别

Answer 1

1、句中语气不同

ought to表达的语气比should强烈，在表示推测时，意为“按常理说应该……”，暗示有很大的可能性，有时可译为“建议或劝告”。

2、主观语境不同

表示出于法令规则、行为准则、道德责任等客观情况而“应该”做某事，通常用ought to；若用should则含有个人意见，强调主观看法。

3、特殊用法不同

在公告、须知或条例中，出于礼貌，常用should。

ought to的一般疑问句形式是将ought提到句首。

例如：She ought to leave now.

她现在应该离开了。

Ought she to leave now?

她现在应该离开了吗？

解析：ought to的一般疑问句的变法和其他句型的一般疑问句变法类似，但是ought to的一般疑问句只提前ought，不提前to

ought to的反意疑问句常常可以和should的反意疑问句互换，要领悟反意疑问句的法则→反意疑问句口诀:前肯后否；前否后肯。该句中前一句为肯定句，所以在反问部分要用否定句。
