Does Chinese have an equivalent to Arabic-style praising grammar (translates to 褒贬句)?
There isn't a certain structure of praising or disparaging something in Chinese actually. The meaning of a Chinese sentence is all about the words it uses. 

If simply expressing approving/disapproving attitude, we may just use 很好/不好（很壞）as below:

-XXX很好
誠信很好

-XXX不好
說謊不好

More naturally, we should append a category noun and use 是 structure:

-誠信是好品質

-說謊是壞行為

Apart from basic 好/壞, in daily life we use various words to show approval/disapproval:

-誠信乃万善之始

-說謊應遭人唾棄

However, words having similar meanings can be distinguished according to their 褒貶色彩. E.g. 深謀遠慮（褒） 老謀深算（中） 深奸巨滑（貶）. And when we use it, the attitude is conveyed by choosing the word itself. I try to write a paragraph and use these kind of words as many as possible:

-以上十年，左右佞臣，肆奸植黨，掠脂斡肉，上下交征！今幸天易明主，國舉良相，深謀遠慮，雷厲風行，斬惡剷奸，還朝堂以清明，社稷以昇平。自此尸位素餐之徒，紛丟權柄，蠹國害民之輩，立撒頭顱。人心大快，莫過於此。
