Sorry, I thought you were going to ask us for mathematical issues (it seems strange, but "ask" is followed by "for": ex.: "
ask for permission". Sometimes it has an object:
ask him for permission).
Well, let's examine the sentence you wrote.
If you go by train you can have quite a comfortable journey, but make sure yet get an express, not a train that stops at all the station.First of all, you should recognize the green text: that are all the expressions regarding the ways you can move:
by train,
by car,
by bus,
on foot.... so it needn't put an article.
I would want to highlight some English constructions. For example, what I stressed in blue is something you must know. The word
quite (there are others with the same rule, but now I don't remember) is always put before the adjective (and the noun) when expressing a considerable number of someone or something (
quite a bit=a considerable length of time or amount;
quite a few=a considerable number of;
quite a sight=something impressive to see;
quite a lot, ...etcetera). Instead, when it's used in a different way, it has different roles inside the sentence, for example: "
be quite!" or "
this restaurant is quite good or
this is quite a good restaurant" or "
I'm not quite sure of what you want".
The last two are the same. I guess you haven't understood the meaning. Read it again, it's easy. He has to get an express, not a train that stops...bla bla bla. Translate it in italian, it's the same.
Please if you have any other question just ask for clarification, I(we're)'m here twentyfour hours a day...
