on course和 as such 这2个词组能不能用几个列子解释一下什么意思

on course 在...的过程中
eg.The plane was on /off course , ie following/not following the right course .飞机航向正确[偏离航向].
as such 照比, 本身,就其本身而论
eg. "a name, as such , means nothing."姓名本身并无意义
eg. "The news came as such a surprise, he was at a loss for things to say."消息来得如此突然让他茫然不知该说什么。
