In the following cases, beer/wine/cruide oil are not countable nouns. Therefore, in order to count them, I added extra information and changed them as follows:
1. Two bottles of beer
2. Two bottles of wine
3. 1,000 gallons of cruide oil
Now my question is this: Do the examples above 1 to 3 take a singular verb form (e.g., "is," "consists of") or a plural verb form(e.g., "are," "consist of")? I checked some websites, and it seems that some people take singular and some people take plural...so, I want to know which is grammatically correct.
I see, nothing is wrong to use the plural form in these cases, right?
As usual, it depends on the context:
Two bottles of beer are better than one! (are refers to two, so it is plural).
Drinking two bottles of beer is more fun than drinking one. (is refers to the act of drinking, not the number of bottles, so it needs to be singular)
The same applies to 2 bottles of wine.
As for 1000 gallons of crude oil, this might be singular or plural too, depending on whether you wished to treat 1000 gallons as being a single unit, like in a tankful, or whether you wished to express 1000 gallons as being a multiple.
Pumping 1000 gallons of crude oil is completed in just 2 minutes. (ie. the whole tank is treated as a single unit where the action is pumping out, therefore singular).
Almost 1000 gallons of crude oil are used during each voyage. (each gallon is measured separately, so we have more than one of them, therefore plural)
Thank you for your additional information and help.
I think I got your points clearly on this matter.
