A guy bought a bike at a store, but he didn't take it with him on that day. After few weeks, he said to me " Could you help me to call the store owner again? because I need to go pick up my bike." In this case, I should say A) " Oh my god, you never went back since then ? " or B) "oh my god, you have never gone back there since then? "

A sounds better than B, but I think I should use B since it's a period of time, from the day he bought the bike to the day he asked me to contact the owner again. Please help me to clairify this, thanks.

2) "since" can be used like " because", to bring out a reason. What are the tenses for since-clause ? Are the followings correct?

a) I will go there since you have asked me.
b) I will go there since you asked me yesterday. Do I need to have " yesterday" at the end ?
c) I think we should go tomorrow since it will be fun.
d) I think we will go since it's a good show.
e) This is a must since they didn't give us much (many) choices.

3) What's the difference between " i.e." and " e.g." ?

A) " Oh my god, you never went back since then ? "
B) "oh my god, you have never gone back there since then? " -- Both are fine as spoken exclamations.

2) "since" can be used like " because", to bring out a reason. What are the tenses for since-clause ? Are the followings correct?

a) I will go there since you have asked / are asking / ask / asked me.
b) I will go there since you asked me yesterday. Do I need to have " yesterday" at the end ?-- Only if you wish to identify the day of the offer.
c) I think we should go tomorrow since it will be fun.-- OK
d) I think we will go since it's a good show.-- OK
e) This is a must since they didn't give us much choice / many choices.

3) What's the difference between " i.e." and " e.g." ?

i.e. (id est) = 'that is', a preface for further clarification
e.g. (exempli gratia) = 'for example', 'such as
'

Thank you, Mr. M.

Could you also let me know why we should say "much choice", not " much choices" ? Does this " much" mean "many" as well? When should we use "much" instead of "many" ?

Sarah
May I answer?

You probably know that we use much for things that can't be counted (much water), and many for things which can be counted (many glasses of water). Choice is a funny thing because it can fall into both categories!

In the non-countable usage, choice is a singular noun that can exist in greater or lesser quantities (like the nouns "freedom" and "work"). This usage is more common in the negative: I don't have much choice.

When choices are countable, then many is used. If you study hard and get good grades, you will have many good choices when it is time for college.
