truism 陈词滥调;不言自明的说法 A truism is a statement that is generally accepted as obviously true and is repeated so often that it has become boring.
例如：Whilst this might sound like a truism, it is nevertheless a crucial problem to address.尽管这可能听起来像是老生常谈，但却是待解决的重要问题。

cliche a phrase or an idea that has been used so often that it no longer has much meaning and is not interesting. 陈词滥调；陈腐的套语
例如：How can it be cliché? It's a fable! It's telling a time-honoured story!
这怎么能是老套呢？这是寓言。是在讲述一个由来已久的故事！

两者基本没有太大区别，truism更强调不言而喻的事实，而cliche更强调老套的说法。

祝同学学习愉快～
