Sentence A: "What you drink can make just as much impact on weight as what you eat." Sentence B: "What you drink can make just as much OF AN impact on weight as what you eat." Is there any subtle difference in the meaning between the two? I've read some discussions on another phrase with similar construction "much difference vs. much of a difference," but the replies are more about the countability of the following noun. Except the noun is countable or uncountable, when would you prefer using one over the other? Or they are always interchangeable?

Omitted articles after the preposition "without"? I searched on COCA(corpus of Contemporary American English) and found that when saying "reasonable explanation," people tend to add in the article "a", which thus makes the phrase become "a reasonable explanation." However, when saying "without reasonable explanation", there is usually no article seen. So, I'm wondering if there is a grammatical rule accounting for this omission. Any explanation?

How do these sentences sound to your native ears? We are trying to improve our command of English by translation exercises. One of us wrote such a sentence and I'm not sure whether it sounds natural: 1. For many people in Chinese world, “The Dream of The Red Chamber” is not only favorable but also seen as an outstanding masterpiece of Chinese literature－even it’s not the only outstanding masterpiece. First, does it sounds natural to use the word "favorable" to describe a literature work and its popularity? Second, how about changing "even" to "even though"? Do both of them sound okay? Does either of them make more sense? Besides, is there any problem with the two sentences below: 2.For many in the Chinese world, Dream of the Red Chamber is not just loved, but deemed as a masterpiece of Chinese literature, though not the only masterpiece. 3.For many Chinese people, Dream of the Red Chamber is not only adored by people, but also regarded as a masterpiece of Chinese literature－despite not being the only masterpiece. Thanks a lot.

Is there any natural or more concise way of saying the following sentences? Is there any natural or more concise way of saying the following sentences? I heard you use present continuous tense as in "one thing about number three is depending on who your grammar teacher is," from 3:37 to 4:46 of the video, and I'm wondering which situation it is for? And it is somehow related to a question that I've been having for so long: I heard a bunch of English native speakers seemingly use present continuous tense in daily conversations for none of the situations mentioned in the video, is it grammatical?
