同学有错应不应该指出来辩论赛，正方该怎么提问

你是正方啊！那怎么辩都能赢。现在的论题大体都一样，没有说提问一两个问题就能把反方打败的！

理论是基础，避免对方提问：没有基础还怎么...之类的话题，必须肯定理论与实践是共同存在的，但是实践更重要！比如学校里学的四年,不如工作实践一年收获多

马克思主义理论早有答案:

略举一二

实践是检验真理的唯一标准!

理论重要,但实践更重要.没有实践的理论,那是苍白的理论.理论是从实践中总结而来的,源于实践.

实践的观点是第一的观点.这是马克思主义活的灵魂.

思维是第二性的,实践是第二性的.即思维和物质何为第一,本源,这是唯心论和唯物论的分水岭.

既便没有理论,不是也可以"摸着石头过河"吗!

上面那段是网上找的（可以给一辩做陈述内容）

真要是提问，大致可以说：哪哪的什么专业的学生学习用功，基础知识特别好，书上内容几乎可以倒背如流，但是让他实际操作的时候却总是不行，请问对方辩友怎么解释这一点？

谁有关于公共场合应不应该吸烟的英文辩论啊

Smoking can enhance memory

据《流行科学网》消息，近日科学家发现给人类健康带来巨大危害的尼古丁或许能使老年痴呆症患者多保持长达半年的记忆力，甚至在动物实验中发现，尼古丁还可以提高动物的记忆力和注意力。 According to "popular scientific network" message, scientists recently discovered that a huge human health hazards of nicotine may enable many patients with dementia to maintain the memory for up to six months, or even in animal experiments found that nicotine can also improve memory and animals attention.

But is there is such a highly toxic alkaloid, the Royal Institute of British scientists conducted a study found that tobacco has an addictive and highly toxic chemical nicotine might improve memory, and the treatment of Alzheimer's disease must have role. Studies have shown that animals eat food that contains nicotine, the more precise finish complex tasks, and can contain more than not eating more animal food nicotine concentration. At the same time, scientists found that nicotine can also stimulate the animal epinephrine (adrenaline is a hormone can improve attention) secretion. Although this role for the normal people are minimal, but the researchers believe that nicotine in inducing people to focus and enhance the role of memory for dementia patients is of great significance, perhaps, it will enable many of these patients to maintain as many as half a year memory.

In addition, the researchers also nicotine and the interaction between cells of the concern, hoping to find the role of nicotine happen to generate more than the role of the chemical substances in order to develop a nicotine can play this role but there is no negative effects of drugs, for the majority of patients with Alzheimer's disease is good news.
