关于however的用法however引导的句子.后面宾语是不是一定要前提的?还是可以前提可以不前提?如however great it is.however late he is.

1、however可以做副词，含义为“但是，可是，不过”。多插在句中，有时放在句首或句尾。
例如：However，they did not seem to have much effect.
不过，他们似乎没有起太大的作用。
He said that it was so; he was mistaken，however.
他说事情就是这样；然而，他错了。
2、however还可以做连词，含义为“不管……如何，多么”，引导让步状语从句。从句的语序为：however+adj./adv.+主语+句子的其他成分。
例如：We shall never succeed，however much we try.
无论我们多么的努力，都不可能成功。
However cold it is，she always goes swimming.
无论天多冷，她总是去游泳。

这是陈述句语序,没有提前不提前的问题.
