1. "这么无耻地为土共说话"，其中"无耻地"是状语，形容说话的方式。这句表达的意思和你说的"为土共说话就是无耻"还是有些不同的。虽然我还没有想出很好的为土共说话但并不无耻的例子，但是就表达的意思来说，你的理解错了。

2. 科学，在不加任何修饰的情况下，指的是对自然规律的研究及其成果。你所谓"你这个科学，应该指的是自然科学"，显然是把科学和打着科学旗号的其它东西搞混了。下面是Academic Press Dictionary of Science and Technology对science的定义：
1. the systematic observation of natural events and conditions in order to discover facts about them and to formulate laws and principles based on these facts. 2. the organized body of knowledge that is derived from such observations and that can be verified or tested by further investigation. 3. any specific branch of this general body of knowledge, such as biology, physics, geology, or astronomy.
