punishment是不可数名字吗？如果写了很多句子，不想用句号，应该用什么符号隔开？英语中没哪些标点符号？

下面的句子有没有错误或不地道的地方？

punishment是不可数名字吗？
是
如果写了很多句子，不想用句号，应该用什么符号隔开？
分号
英语中没哪些标点符号？
好像除了顿号以外都有

下面的句子有没有错误或不地道的地方？
There are fiece dabate about this topic nowadays,some people think ........but other people claim......
用THERE BE有点别扭,不如改成FIERCE DEBATES WERE CARRIED OUT...(其他不变).

Weighing pros and cons both of sides,i incline that ........
By weighing both the pros and the cons, I incline that...(PROS AND CONS本来就有"两面"的意思.)

The explanations to this phenomenon are very complex including very many factors.
......complex -- they include many factors/aspects. (如果一句话说不清楚,宁愿分两句话.)

Maybe the best policy is to regulate it so as to maximize its advantages and minimize its disadvantages.
这句话暂时没意见,因为我不知道IT指什么,照现在看来,一旦把IT所指代的事情代入,可能会造成指代不清.

One thing is for sure that those people must be punished who violate some certain regulations
One thing is for sure -- those people who violate certain regulations must be punished. OR One sure thing/One thing for sure is that those people who...
SOME 和 CERTAIN 不要放在一起用,作用重叠了.
