问题：Ifyoucannotunderstandyourteacher? 
If you cannot understand your teachers or that they are eaking too quickly, don't hesitate to ask them to slow down or speak more clearly. that后面显然只是由or连接的条件状语从句之一。请解释or that中that的作用，我感觉怎么好像是多余的 
回答：这似乎是楼主/书籍/试卷/资料等的印刷遗漏，我估计原句应该在or后面有一个(think)，即“或认为...”，这样可加that领起的宾语从句.
个人意见，仅供参考。
